How can I stop using food to cope with negative emotions?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/inge-gnatt-1425767">Inge Gnatt</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> Have you ever noticed changes in your eating habits when you are sad, bored or anxious? Many people report eating either more, or less, as a way of helping them to cope when they experience difficult emotions. Although this is a very normal response, it can take the pleasure out of eating, and can become distressing and bring about other feelings of <a href="https://doi.org/10.1016/j.eatbeh.2018.02.008">shame and self-criticism</a>. Adding to the complexity of it all, we live in a world where <a href="https://butterfly.org.au/diet-culture-101/">diet culture</a> is unavoidable, and our relationship to eating, food and body image can become complicated and confusing. <h2>Emotional eating is common</h2> “Emotional eating” refers to the eating behaviours (typically eating more) that occur in response to difficult emotions. <a href="https://doi.org/10.3390/ijerph18041744">Research shows</a> around 20% of people regularly engage in emotional eating, with a higher prevalence <a href="https://doi.org/10.1371/journal.pone.0285446">among adolescents</a> and women. In a <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0285446#sec012">study</a> of more than 1,500 adolescents, 34% engaged in emotional eating while sad and 40% did so while anxious. Foods consumed are often fast-foods and other energy-dense, nutrient-poor convenience foods. <h2>Stress, strong emotions and depression</h2> For some people, emotional eating was simply a <a href="https://doi.org/10.1038/s41598-017-09519-0">habit formed earlier in life</a> that has persisted over time. But other factors might also contribute to the likelihood of emotional eating. The physiological effects of stress and strong emotions, for example, can influence hormones such as <a href="https://doi.org/10.1016/S0306-4530(00)00035-4">cortisol, insulin and glucose</a>, which can also increase appetite. Increased impulsivity (<a href="https://doi.org/10.1176/appi.ajp.158.11.1783">behaving</a> before thinking things through), vulnerability to depression, a tendency to ruminate and <a href="https://doi.org/10.1080/1047840X.2014.940781">difficulties regulating emotions</a> also <a href="https://doi.org/10.1097/FBP.0b013e328357bd4e">increase the likelihood</a> of emotional eating. <h2>So what do you do?</h2> First, know that fluctuations in eating are normal. However, if you find that the way you eat in response to difficult emotions is not working for you, there are a few things you can do. Starting with small things that are achievable but can have a huge impact, such as prioritising <a href="https://theconversation.com/no-sleep-challenge-the-dangers-of-sleep-deprivation-236608">getting enough sleep</a> and <a href="https://insideoutinstitute.org.au/podcasts/episode-3-the-mindful-dietitian-fiona-sutherland">eating regularly</a>. Then, you can start to think about how you handle your emotions and hunger cues. <h2>Expand your emotional awareness</h2> Often we label emotions as good or bad, and this can result in fear, avoidance, and <a href="https://youtu.be/NDQ1Mi5I4rg?si=lv9d8qjUThSsemXG">unhelpful coping strategies</a> such as emotional eating. But it’s also important to <a href="https://www.pspnet.ca/assets/the-gottman-institute-the-feeling-wheel-v2.pdf">differentiate</a> the exact emotion. This might be feeling isolated, powerless or victimised, rather than something as broad as sad. By <a href="https://headspace.org.au/online-and-phone-support/interactive-tools/activities/understanding-emotions/">noticing</a> what the emotion is, we can bring curiosity to what it means, how we feel in our minds and bodies, and how we think and behave in response. <h2>Tap into your feelings of hunger and fullness</h2> Developing an intuitive way of eating is another helpful strategy to promote <a href="https://insideoutinstitute.org.au/blog/what-is-normal-eating">healthy eating behaviours</a>. Intuitive eating means recognising, understanding and responding to internal signals of hunger and fullness. This might mean tuning in to and acknowledging physical hunger cues, responding by eating food that is nourishing and enjoyable, and identifying sensations of fullness. Intuitive eating <a href="https://doi.org/10.1002/eat.23509">encourages flexibility</a> and thinking about the pleasure we get from food and eating. This style of eating also allows us to enjoy eating out with friends, and sample local delicacies when travelling. It can also reduce the psychological distress from feeling out of control with your <a href="https://doi.org/10.1016/j.jand.2013.12.024">eating</a> habits and the associated negative <a href="https://doi.org/10.1016/j.appet.2015.10.012">body image</a>. <h2>When is it time to seek help?</h2> For some people, the thoughts and behaviours relating to food, eating and body image can negatively impact their life. Having the support of friends and family, accessing <a href="https://nedc.com.au/eating-disorder-resources/interactive-digital-resource-for-eating-disorders">online resources</a> and, in some instances, seeing a trained professional, can be very helpful. There are many <a href="https://doi.org/10.1007/s00787-020-01498-4">therapeutic interventions</a> that work to <a href="https://doi.org/10.1016/j.copsyc.2015.02.010">improve aspects</a> associated with emotional eating. These will depend on your situation, needs, stage of life and other factors, such as whether you are <a href="https://nedc.com.au/eating-disorders/types/neurodivergence">neurodivergent</a>. The best approach is to engage with someone who can bring compassion and understanding to your personal situation, and work with you collaboratively. This work might include: <ul> <li>unpacking some of the patterns that could be underlying these emotions, thoughts and behaviours</li> <li>helping you to discover your emotions</li> <li>supporting you to process other experiences, such as trauma exposure</li> <li>developing a more flexible and intuitive way of eating.</li> </ul> One of the dangers that can occur in response to emotional eating is the temptation to diet, which can lead to disordered eating, and eating disorder behaviours. Indicators of a potential <a href="https://nedc.com.au/eating-disorders/eating-disorders-explained/whats-an-eating-disorder">eating disorder</a> can include: <ul> <li>recent rapid weight loss</li> <li>preoccupation with weight and shape (which is usually in contrast to other people’s perceptions)</li> <li>eating large amounts of food within a short space of time (two hours or less) and feeling a sense of loss of control</li> <li>eating in secret</li> <li>compensating for food eaten (with vomiting, exercise or laxatives).</li> </ul> <a href="https://nedc.com.au/eating-disorders/treatment-and-recovery/treatment-options">Evidence-based approaches</a> can support people experiencing eating disorders.

New research proves travelling can slow down the ageing process

It turns out that going on holiday is good for you in more ways than one. According to new research conducted at Edith Cowan University in Western Australia, travelling can actually slow the ageing process both physically and mentally. The study, published in the <a title="Journal of Travel Research" href="https://journals.sagepub.com/doi/10.1177/00472875241269892#:~:text=The%20principle%20of%20entropy%20increase%20provides%20a%20dynamic%20perspective%20to,Silva%20%26%20Annamalai%2C%202008)." target="_blank" rel="noopener">Journal of Travel Research</a>, is believed to be the first-ever that applied the theory of entropy - the general trend of the universe towards death and disorder – to tourism. "Tourism isn't just about leisure and recreation. It could also contribute to people's physical and mental health," ECU PhD candidate Fangli Hu said. "Ageing, as a process, is irreversible. While it can't be stopped, it can be slowed down." According to the research, travelling, exploring new corners of the world and engaging in unique and relaxing activities can stimulate stress responses and elevate metabolic rates, positively influencing metabolic activities and the body's self-organising capabilities. "Leisurely travel activities might help alleviate chronic stress, dampen over-activation of the immune system, and encourage normal functioning of the self-defence system," Fangli added. While some people prefer relaxing holidays, others prefer to stay on their feet and keep active during their travels, enjoying the many well-known benefits of exercise. It can "enhance the body's immune function and self-defence capabilities, bolstering its hardiness to external risks". In response to their study, the experts suggested that "travel therapy could serve as a groundbreaking health intervention." Despite the positive results of the research, experts also warned that travelling can exposed to infectious diseases, accidents, injuries, violence, water and food safety issues, and concerns related to inappropriate tourism engagement, which in turn will have the opposite effect on our health. "Conversely, tourism can involve negative experiences that potentially lead to health problems, paralleling the process of promoting entropy increase," Fangli said. Image credits: Shutterstock

Travel Tips

MSG is back. Is the idea it’s bad for us just a myth or food science?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> MSG is making a comeback. The internet’s favourite cucumber salad recipe includes fish sauce, cucumber, garlic and – as the video’s creator Logan tells us with a generous sprinkle from the bag – “MSG, obviously”. But for many of us, it’s not obvious. Do you have a vague sense MSG is unhealthy but you’re not sure why? Here is the science behind monosodium glutamate, how it got a bad rap, and whether you should add it to your cooking. <h2>What is MSG?</h2> Monosodium glutamate (MSG) is a sodium salt of glutamic acid, one of the amino acids that make up proteins. It occurs naturally in <a href="https://www.tandfonline.com/doi/full/10.1080/10942912.2017.1295260#d1e167">foods</a> such as mature cheeses, fish, beef, mushrooms, tomatoes, onion and garlic. It provides their savoury and “meaty” flavour, known as <a href="https://www.sciencedirect.com/science/article/pii/S0022316622140186">umami</a>. MSG has been used to season food for <a href="https://wjpsonline.com/index.php/wjps/article/view/effects-monosodium-glutamate-human-health-review">more than 100 years</a>. Traditionally it <a href="https://pubs.acs.org/doi/epdf/10.1021/ed081p347?ref=article_openPDF">was extracted</a> from seaweed broth, but now it’s made by fermenting starch in sugar beets, sugar cane and molasses. Today it’s widely used as a flavour enhancer in many dishes and pre-packaged goods, including soups, condiments and processed meats. There is no chemical difference between the MSG found in food and the additive. <h2>Is it safe?</h2> For most people, yes. MSG is a safe and authorised additive, according to the Australian agency that regulates food. This corresponds with food standards in the <a href="https://www.fda.gov/food/food-additives-petitions/questions-and-answers-monosodium-glutamate-msg">United States</a>, <a href="https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A02008R1333-20201223#tocId3">European Union and United Kingdom</a>. Two major <a href="https://www.foodstandards.gov.au/sites/default/files/consumer/additives/msg/Documents/MSG%20Technical%20Report.pdf">safety reviews</a> have been conducted: one in 1987 by a United Nations expert committee and another 1995 by the Federation of American Societies for Experimental Biology. Both concluded MSG was safe for the general population. In 2017 the <a href="https://www.efsa.europa.eu/en/efsajournal/pub/4910">European Food Safety Authority</a> updated its stance and set a recommended limit based on body weight, aimed to prevent headaches and increased blood pressure. That limit is still higher than most people consume. The authority says an 80kg person should not have more than 2.4g of added MSG per day. <a href="https://www.nature.com/articles/1602526">For reference</a>, Europeans average less than a gram per day (0.3-1 gram), while in Asia intake is somewhere between 1.2-1.7 grams a day. Food Standards Australia New Zealand says the European update does not raise any new safety concerns not already assessed. <h2>Isn’t it bad for me?</h2> Despite the evidence, the idea MSG is dangerous persists. Its notorious reputation can be traced back to a <a href="https://news.colgate.edu/magazine/2019/02/06/the-strange-case-of-dr-ho-man-kwok/">hoax letter</a> published in the <a href="https://www.nejm.org/doi/full/10.1056/NEJM196805162782014">New England Journal of Medicine</a> in 1968. A doctor claiming to have experienced palpitations, numbness and fatigue after eating at a Chinese restaurant suggested MSG could be to blame. With a follow-up article in the <a href="https://www.nytimes.com/1968/05/19/archives/-chinese-restaurant-syndrome-puzzles-doctors.html">New York Times</a>, the idea of “Chinese Restaurant Syndrome” took off. Eating MSG was associated with a range of symptoms, including headache, hives, throat swelling, itching and belly pain. However an <a href="https://www.sciencedirect.com/science/article/pii/027869159390012N?via%3Dihub">early randomised control trial</a> showed no difference in these symptoms between people who were given MSG versus a placebo. This has since been confirmed in a <a href="https://ift.onlinelibrary.wiley.com/doi/full/10.1111/1541-4337.12448">review of many studies</a>. <h2>Can MSG cause reactions?</h2> A very small percentage of people may have hypersensitivities to MSG. The reported reaction is now known as MSG symptom complex, rather than so-called Chinese restaurant syndrome, with its <a href="https://www.jandonline.org/article/S2212-2672(21)00068-X/abstract#:%7E:text=A%20New%20York%20Times%20piece,connecting%20MSG%20to%20health%20outcomes.">problematic</a> racial connotations. Symptoms are usually mild, short-term and don’t need treatment. <a href="https://www.sciencedirect.com/science/article/pii/S0091674999703714">One study</a> looked at 100 people with asthma, 30 of whom believed they had hypersensitivities to MSG. However when participants were blinded to whether they were consuming MSG, not one reported a reaction. If you believe you do react to added MSG, it’s relatively easy to avoid. In Australia, it is <a href="https://www.foodstandards.gov.au/consumer/additives/msg">listed</a> in ingredients as either monosodium glutamate or flavour enhancer 621. <h2>Is it better than table salt?</h2> Using MSG instead of regular salt may help <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6893472/">reduce</a> your overall sodium intake, as MSG <a href="https://www.medicalnewstoday.com/articles/msg-what-the-science-says-about-its-safety#Uses-of-MSG">contains</a> about one third the amount of sodium. <a href="https://pubmed.ncbi.nlm.nih.gov/21372742/">One study</a> found people who ate soup seasoned with MSG rather than salt actually liked it more. They still found it salty to taste, but their sodium intake was reduced by 18%. MSG still contains sodium, so high use is associated with increased <a href="https://pubmed.ncbi.nlm.nih.gov/21372742/">blood pressure</a>. If you’re using MSG as a substitute and you have high blood pressure, you should closely monitor it (just as you would with other salt products). <h2>Should I use MSG in my cooking?</h2> If you want to – yes. Unless you are one of the rare people with hypersensitivities, enhancing the flavour of your dish with a sprinkle of MSG will not cause any health problems. It could even help reduce how much salt you use. If you’re <a href="https://www.tandfonline.com/doi/full/10.1080/25765299.2020.1807084#d1e199">vegetarian or vegan</a>, cooking with MSG could help add the umami flavour you may miss from animal products such as meat, fish sauce and cheese. But buying foods with added MSG? Be aware, many of them will also be <a href="https://www.cambridge.org/core/journals/public-health-nutrition/article/un-decade-of-nutrition-the-nova-food-classification-and-the-trouble-with-ultraprocessing/2A9776922A28F8F757BDA32C3266AC2A">ultra-processed</a> and it’s that – not the MSG – that’s associated with poor physical and mental <a href="https://www.mdpi.com/2072-6643/14/1/174">health outcomes</a>.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/237871/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, Program Director of Nutrition and Food Sciences, Accredited Practising Dietitian, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Food & Wine

What causes food cravings? And what can we do about them?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/gabrielle-weidemann-91497">Gabrielle Weidemann</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> and <a href="https://theconversation.com/profiles/justin-mahlberg-1634725">Justin Mahlberg</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Many of us try to eat more fruits and vegetables and less ultra-processed food. But why is sticking to your goals so hard? High-fat, sugar-rich and salty foods are simply so enjoyable to eat. And it’s not just you – we’ve evolved that way. These foods <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5928395/">activate</a> the brain’s reward system because in the past they were <a href="https://doi.org/10.1037/a0030684">rare</a>. Now, they’re all around us. In wealthy modern societies we are bombarded by <a href="https://theconversation.com/junk-food-is-promoted-online-to-appeal-to-kids-and-target-young-men-our-study-shows-234285">advertising</a> which intentionally reminds us about the sight, smell and taste of calorie-dense foods. And in response to these powerful cues, our brains respond just as they’re designed to, triggering <a href="https://doi.org/10.1111/obr.12354">an intense urge</a> to eat them. Here’s how food cravings work and what you can do if you find yourself hunting for sweet or salty foods. <h2>What causes cravings?</h2> A food craving is an intense desire or urge to eat something, <a href="https://pubmed.ncbi.nlm.nih.gov/15589112/">often focused on a particular food</a>. We are programmed to learn how good a food tastes and smells and where we can find it again, especially if it’s high in fat, sugar or salt. Something that <a href="https://doi.org/10.1111/obr.12354">reminds us</a> of enjoying a certain food, such as an eye-catching ad or delicious smell, can cause us to <a href="https://doi.org/10.1111/obr.12354">crave it</a>. The cue triggers a physical response, increasing saliva production and gastric activity. These responses are relatively automatic and difficult to control. <h2>What else influences our choices?</h2> While the effect of cues on our physical response is relatively automatic, what we do next is influenced by <a href="https://journals.sagepub.com/doi/pdf/10.1177/1090198107303308">complex</a> factors. Whether or not you eat the food might depend on things like cost, whether it’s easily available, and if eating it would align with your health goals. But it’s usually hard to keep healthy eating in mind. This is because we tend to prioritise a more immediate reward, like the <a href="https://doi.org/10.1016/j.physbeh.2010.04.029">pleasure of eating</a>, over one that’s delayed or abstract – including health goals that will make us feel good in the long term. <a href="https://doi.org/10.1016/S0022-3999(00)00076-3">Stress</a> can also make us eat more. When hungry, we <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8656885/">choose larger portions</a>, underestimate calories and find eating more <a href="https://www.sciencedirect.com/science/article/pii/S0195666315000793">rewarding</a>. <h2>Looking for something salty or sweet</h2> So what if a cue prompts us to look for a certain food, but it’s not available? <a href="https://doi.org/10.1016/j.appet.2014.04.005">Previous research</a> suggested you would then look for anything that makes you feel good. So if you saw someone eating a doughnut but there were none around, you might eat chips or even drink alcohol. But our <a href="https://doi.org/10.1016/j.appet.2024.107640">new research</a> has confirmed something you probably knew: it’s more specific than that. If an ad for chips makes you look for food, it’s likely a slice of cake won’t cut it – you’ll be looking for something salty. Cues in our environment don’t just make us crave food generally, they prompt us to look for certain food “categories”, such as salty, sweet or creamy. <h2>Food cues and mindless eating</h2> Your <a href="https://core.ac.uk/download/pdf/161283824.pdf">eating history</a> and <a href="https://doi.org/10.1002/eat.24179">genetics</a> can also make it harder to suppress food cravings. But don’t beat yourself up – relying on willpower alone is <a href="https://doi.org/10.1016/j.appet.2015.01.004">hard</a> for almost everyone. Food cues are so powerful they can prompt us to <a href="https://doi.org/10.1177/0956797613484043">seek</a> out a certain food, even if we’re not overcome by a particularly <a href="https://doi.org/10.1177/0956797613484043">strong urge</a> to eat it. The effect is more intense if the food is easily available. This helps explain why we can eat an entire large bag of chips that’s in front of us, even though our pleasure decreases as we <a href="https://doi.org/10.1016/0031-9384(81)90310-3">eat</a>. Sometimes we use finishing the packet as the signal to stop <a href="https://doi.org/10.1016/j.physbeh.2015.03.025">eating</a> rather than hunger or desire. <h2>Is there anything I can do to resist cravings?</h2> We largely don’t have control over cues in our environment and the cravings they trigger. But there are some ways you can try and control the situations you make food choices in. <ul> <li> Acknowledge your craving and think about a healthier way to satisfy it. For example, if you’re craving chips, could you have lightly-salted nuts instead? If you want something sweet, you could try fruit. </li> <li> Avoid shopping when you’re hungry, and make a list beforehand. Making the most of supermarket “click and collect” or delivery options can also help avoid ads and impulse buys in the aisle. </li> <li> At home, have fruit and vegetables easily available – and easy to see. Also have other nutrient dense, fibre-rich and unprocessed foods on hand such as nuts or plain yoghurt. If you can, remove high-fat, sugar-rich and salty foods from your environment. </li> <li> Make sure your goals for eating are <a href="https://www.aafp.org/pubs/fpm/issues/2018/0300/p31.html">SMART</a>. This means they are specific, measurable, achievable, relevant and time-bound. </li> <li> Be kind to yourself. Don’t beat yourself up if you eat something that doesn’t meet your health goals. Just keep on trying.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/237035/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> </li> </ul> <a href="https://theconversation.com/profiles/gabrielle-weidemann-91497">Gabrielle Weidemann</a>, Associate Professor in Psychological Science, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> and <a href="https://theconversation.com/profiles/justin-mahlberg-1634725">Justin Mahlberg</a>, Research Fellow, Pyschology, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Why do I need to take some medicines with food?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/mary-bushell-919262">Mary Bushell</a>, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> Have you ever been instructed to take your medicine with food and wondered why? Perhaps you’ve wondered if you really need to? There are varied reasons, and sometimes complex science and chemistry, behind why you may be advised to take a medicine with food. To complicate matters, some similar medicines need to be taken differently. The antibiotic amoxicillin with clavulanic acid (sold as Amoxil Duo Forte), for example, is recommended to be taken with food, while amoxicillin alone (sold as Amoxil), can be taken with or without food. Different brands of the same medicine may also have different recommendations when it comes to taking it with food. <h2>Food impacts drug absorption</h2> Food can affect how fast and how much a drug is absorbed into the body in up to <a href="https://academic.oup.com/jpp/article-abstract/71/4/510/6122024?login=false">40% of medicines</a> taken orally. When you have food in your stomach, the makeup of the digestive juices change. This includes things like the fluid volume, thickness, pH (which becomes less acidic with food), surface tension, movement and how much salt is in your bile. These changes can impair or enhance drug absorption. Eating a meal also delays how fast the contents of the stomach move into the small intestine – this is known as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9505616/">gastric emptying</a>. The small intestine has a large surface area and rich blood supply – and this is the primary site of drug absorption. Eating a larger meal, or one with lots of fibre, delays gastric emptying more than a smaller meal. Sometimes, health professionals will advise you to take a medicine with food, to help your body absorb the drug more slowly. But if a drug can be taken with or without food – such as paracetamol – and you want it to work faster, take it on an empty stomach. <h2>Food can make medicines more tolerable</h2> Have you ever taken a medicine on an empty stomach and felt nauseated soon after? Some medicines can cause stomach upsets. Metformin, for example, is a drug that reduces blood glucose and treats type 2 diabetes and polycystic ovary syndrome. It commonly causes gastrointestinal symptoms, with <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4452716/">one in four users affected</a>. To combat these side effects, it is generally recommended to be taken with food. The same <a href="https://amhonline.amh.net.au/auth">advice</a> is given for corticosteroids (such as prednisolone/prednisone) and certain antibiotics (such as doxycycline). Taking some medicines with food makes them more tolerable and improves the chance you’ll take it for the duration it’s prescribed. <h2>Can food make medicines safer?</h2> Ibuprofen is one of the most widely used over-the-counter medicines, with around one in five Australians reporting use <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/medications/latest-release">within a two-week period</a>. While effective for pain and inflammation, ibuprofen can impact the stomach by inhibiting protective prostaglandins, increasing the risk of <a href="https://www.tandfonline.com/doi/full/10.1586/14737175.6.11.1643#d1e212">bleeding, ulceration and perforation</a> with long-term use. But there <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4574824/">isn’t enough research</a> to show taking ibuprofen with food reduces this risk. Prolonged use may also affect kidney function, particularly in those with pre-existing conditions or dehydration. The <a href="https://amhonline.amh.net.au/auth">Australian Medicines Handbook</a>, which guides prescribers about medicine usage and dosage, advises taking ibuprofen (sold as Nurofen and Advil) with a glass of water – or with a meal if it upsets your stomach. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4574824/">A systematic review published in 2015</a> found food delays the transit of ibuprofen to the small intestine and absorption, which delays therapeutic effect and the time before pain relief. It also found taking short courses of ibuprofen without food reduced the need for additional doses. To reduce the risk of ibuprofen causing damage to your stomach or kidneys, use the lowest effective dose for the shortest duration, stay hydrated and avoid taking other <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/medications-non-steroidal-anti-inflammatory-drugs">non-steroidal anti-inflammatory medicines</a> at the same time. For people who use ibuprofen for prolonged periods and are at higher risk of gastrointestinal side effects (such as people with a history of ulcers or older adults), your prescriber may start you on a <a href="https://australianprescriber.tg.org.au/articles/peptic-ulcer-disease-and-non-steroidal-anti-inflammatory-drugs.html">proton pump inhibitor</a>, a medicine that reduces stomach acid and protects the stomach lining. <h2>How much food do you need?</h2> When you need to take a medicine with food, how much is enough? Sometimes a full glass of milk or a couple of crackers may be enough, for medicines such as prednisone/prednisolone. However, most head-to-head studies that compare the effects of a medicine “with food” and without, usually use a heavy meal to define “with food”. So, a cracker may not be enough, particularly for those with a sensitive stomach. A more substantial meal that includes a mix of fat, protein and carbohydrates is generally advised. Your health professional can advise you on which of your medicines need to be taken with food and how they interact with your digestive system.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/235782/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/mary-bushell-919262">Mary Bushell</a>, Clinical Associate Professor in Pharmacy, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

5 foods to add to your shopping list to save money – and they’re good for you too

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/clare-collins-7316">Clare Collins</a>, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a> Food prices are <a href="https://www.abc.net.au/news/2024-06-13/anglicare-cost-living-unemployment-groceries-fuel-rent-prices/103972166?utm_medium=social&utm_content=sf273549397&utm_campaign=abc&utm_source=linkedin.com&sf273549397=1">adding pressure on household budgets</a>, especially for Australians on the lowest incomes. To help save money on the weekly groceries, consider adding these five staples to your shopping trolley: eggs, oats, carrots, UHT milk and apples. These foods rate highly on the <a href="https://pubmed.ncbi.nlm.nih.gov/20181811/">nutrient-rich foods index</a> and on cost, meaning they represent good value for money when it comes to buying nutritious food. Loading up on these items helps push more expensive, less nutritious foods out of your trolley. Keeping a supply at your place will also save extra trips to the shops, which saves petrol and time. <h2>1. Eggs</h2> Eggs are extremely good value at around A$6 a dozen (50 cents an egg). Meat, chicken and fish prices vary from $12 a kilo for mince, $12–$20 a kilo for chicken, to $20–$50 a kilo for steak and fish depending on cut or type. Selecting the cheapest cuts still costs $2–$3 a serve, compared to two eggs at a $1 serve. When you swap a red meat meal for an eggy dish, this can add up to a big saving. Try our egg recipes on the <a href="https://nomoneynotime.com.au/healthy-easy-recipes/filter/meals--dinner,lunch/superfoods--eggs">No Money No Time website</a>, from <a href="https://nomoneynotime.com.au/healthy-easy-recipes/sweetcorn-and-zucchini-fritters">fritters</a>, to <a href="https://nomoneynotime.com.au/healthy-easy-recipes/mushroom-omelette">omelettes</a>, or <a href="https://nomoneynotime.com.au/healthy-easy-recipes/clares-rainbow-rice">fried rice</a>. These recipes also help use up other items you have in the pantry, fridge and veggie crisper. Eggs are a good <a href="https://www.australianeggs.org.au/nutrition/nutrients-and-vitamins">source</a> of protein and also contain choline, lutein and zeaxanthin, vitamins A, B2, B12, D, E and folate, and minerals iron, zinc, iodine and selenium. For people concerned about eggs raising cholesterol, a <a href="https://pubmed.ncbi.nlm.nih.gov/38370115/">recent review of research evidence</a> concluded there wasn’t likely to be any adverse effect on overall disease risk when consuming up to one egg a day. <h2>2. Rolled oats</h2> Rolled oats vary a lot in price from about $2 a kilogram for “own brand”, up to $9 for premium varieties. Oats are really <a href="https://nomoneynotime.com.au/healthy-easy-recipes/filter/keywords--Oats">versatile</a>. For breakfast you can make <a href="https://nomoneynotime.com.au/healthy-easy-recipes/microwave-porridge">porridge</a>, <a href="https://nomoneynotime.com.au/healthy-easy-recipes/easy-overnight-oats">overnight oats,</a> DIY muesli or <a href="https://nomoneynotime.com.au/healthy-easy-recipes/gingerbread-granola">granola</a>. Oats make a pastry substitute for a <a href="https://nomoneynotime.com.au/healthy-easy-recipes/clares-rolled-oats-quiche">quick and easy quiche base</a>. Or blitz them in a food processor and use as a breadcrumb substitute. For dessert, you can use them to top a comforting <a href="https://nomoneynotime.com.au/healthy-easy-recipes/wholegrain-apple-crumble">apple crumble</a>. <a href="https://www.glnc.org.au/resource/oats-2/">Oats are a wholegrain</a>, meaning they retain every part of the original grain – the germ, bran and outer layers – and hence more fibre and nutrients. Oats are a rich in beta-glucan, a soluble fibre that <a href="https://pubmed.ncbi.nlm.nih.gov/34236436/">helps lower blood cholesterol levels</a> by binding with bile acids in the gut, meaning they can’t be converted into LDL (bad) cholesterol. They <a href="https://www.glnc.org.au/resource/oats-2/">also contain</a> B vitamins of thiamin (b1), riboflavin (B2), niacin (B3), pyridoxine (B6), pantothenic acid (B5) and folate (B9), as well as vitamin E and the minerals iron, zinc, magnesium, phosphorus and potassium. <h2>3. Carrots</h2> It’s hard to get better value than a bag of carrots at about $2.50 a kilo. They last for ages in the fridge and can be eaten raw, as carrot sticks or with <a href="https://nomoneynotime.com.au/healthy-easy-recipes/moroccan-carrot-dip">carrot dip</a>, or baked to make carrot veggie “<a href="https://nomoneynotime.com.au/healthy-easy-recipes/vegetable-chips">chips</a>”. Try grating carrot as an extra on a salad roll or <a href="https://nomoneynotime.com.au/healthy-easy-recipes/basic-beef-burgers">burger</a>, or mixed into grated cheese to extend it when topping tacos, pasta or pizza, or even a dish like <a href="https://nomoneynotime.com.au/healthy-easy-recipes/carrot-and-cauliflower-macaroni-cheese">mac and cheese</a>. Other versatile uses include soup, <a href="https://nomoneynotime.com.au/healthy-easy-recipes/carrot-puree">carrot mash</a>, <a href="https://nomoneynotime.com.au/healthy-easy-recipes/baked-carrots-with-honey-thyme">roasted carrots</a> or, for something sweet, carrot muffins or <a href="https://nomoneynotime.com.au/healthy-easy-recipes/easy-carrot-cake-bliss-balls">bliss balls</a>. Carrots are rich in the carotenoids <a href="https://ods.od.nih.gov/factsheets/VitaminA-HealthProfessional/">alpha-carotene and beta-carotene</a>, which get converted into vitamin A in the body and used in antibody production and to maintain <a href="https://ods.od.nih.gov/factsheets/VitaminA-Consumer/">healthy functioning</a> of your eyes, skin, lungs and gut. <h2>4. Longlife skim milk</h2> Longlife skim milk costs about $1.60 a litre. While some fresh varieties are around the same price, the value of longlife milk is that you can keep a store of it in the cupboard, meaning you never run out and it has a long shelf life. Milk makes great <a href="https://nomoneynotime.com.au/healthy-easy-recipes/banana-breakfast-smoothie">smoothies</a> and is an essential ingredient in dishes from quiche to <a href="https://nomoneynotime.com.au/healthy-easy-recipes/cauliflower-cheese-bake">cauliflower cheese</a> to <a href="https://nomoneynotime.com.au/healthy-easy-recipes/clares-lemon-orange-delicious">lemon delicious</a> pudding. <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/milk#nutrients-in-milk">Milk contains</a> protein, calcium, magnesium, zinc, potassium and vitamins A, B2 and B12. Research shows regular milk consumption is <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/milk#milk-and-health-conditions">associated with</a> a lower risk of developing osteoporosis, high blood pressure, type 2 diabetes, heart disease and colon cancer. <h2>5. Apples</h2> A bag of apples costs about $4 or 60 cents an apple and $4–$5 for a large can of stewed apple. Apples make a portable snack. Add <a href="https://nomoneynotime.com.au/healthy-easy-recipes/comforting-apple-porridge">them to porridge</a>, serve <a href="https://nomoneynotime.com.au/healthy-easy-recipes/pork-loin-rolls">with pork</a>, <a href="https://nomoneynotime.com.au/healthy-easy-recipes/carrot-and-apple-coleslaw-with-mustard-vinaigrette">in coleslaw</a> or in <a href="https://nomoneynotime.com.au/healthy-easy-recipes/wholegrain-apple-crumble">apple crumble</a>. Apples <a href="https://pubmed.ncbi.nlm.nih.gov/35502671/">contain</a> dietary fibre and pectin, vitamin B6 and C, and the minerals potassium, calcium, nitrogen, magnesium and traces of zinc, iron and copper. In <a href="https://pubmed.ncbi.nlm.nih.gov/31667463/">observational studies</a>, people who ate more apples had a lower risk of heart disease, stroke, type 2 diabetes and death from any cause.

Food & Wine

Food and exercise can treat depression as well as a psychologist, our study found. And it’s cheaper

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/adrienne-oneil-268324">Adrienne O'Neil</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> and <a href="https://theconversation.com/profiles/sophie-mahoney-1557294">Sophie Mahoney</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Around <a href="https://www.aihw.gov.au/getmedia/6b19e493-0ebe-420f-a9a3-e48b26aace9f/aihw-aus-249-ib.pdf?v=20240628145747&inline=true">3.2 million</a> Australians live with depression. At the same time, <a href="https://www.aihw.gov.au/getmedia/6b19e493-0ebe-420f-a9a3-e48b26aace9f/aihw-aus-249-ib.pdf?v=20240628145747&inline=true">few</a> Australians meet recommended dietary or physical activity guidelines. What has one got to do with the other? Our world-first trial, <a href="https://www.thelancet.com/journals/lanwpc/article/PIIS2666-6065%2824%2900136-6/fulltext">published this week</a>, shows improving diet and doing more physical activity can be as effective as therapy with a psychologist for treating low-grade depression. Previous studies (including <a href="https://link.springer.com/article/10.1186/s12916-017-0791-y">our own</a>) have found “lifestyle” therapies are effective for depression. But they have never been directly compared with psychological therapies – until now. Amid a nation-wide <a href="https://www.health.gov.au/sites/default/files/2023-10/national-mental-health-workforce-strategy-2022-2032.pdf">shortage</a> of mental health professionals, our research points to a potential solution. As we found lifestyle counselling was as effective as psychological therapy, our findings suggest dietitians and exercise physiologists may one day play a role in managing depression. <h2>What did our study measure?</h2> During the prolonged COVID lockdowns, Victorians’ distress levels were <a href="https://onlinelibrary.wiley.com/doi/full/10.5694/mja2.50831">high and widespread</a>. Face-to-face mental health services were limited. Our trial targeted people living in Victoria with elevated distress, meaning at least mild depression but not necessarily a diagnosed mental disorder. Typical symptoms included feeling down, hopeless, irritable or tearful. We partnered with our <a href="https://www.barwonhealth.org.au/mhdas/">local mental health service</a> to recruit 182 adults and provided group-based sessions on Zoom. All participants took part in up to six sessions over eight weeks, facilitated by health professionals. Half were randomly assigned to participate in a program co-facilitated by an accredited practising dietitian and an exercise physiologist. That group – called the lifestyle program – developed nutrition and movement goals: <ul> <li>eating a wide variety of foods</li> <li>choosing high-fibre plant foods</li> <li>including high quality fats</li> <li>limiting discretionary foods, such as those high in saturated fats and added sugars</li> <li>doing enjoyable physical activity.</li> </ul> The second group took part in psychotherapy sessions convened by two psychologists. The psychotherapy program used cognitive behavioural therapy (CBT), the gold standard for treating depression in <a href="https://jamanetwork.com/journals/jamapsychiatry/article-abstract/2730724">groups and when delivered remotely</a>. In both groups, participants could continue existing treatments (such as taking antidepressant medication). We gave both groups <a href="https://link.springer.com/article/10.1186/s12888-022-03840-3">workbooks and hampers</a>. The lifestyle group received a food hamper, while the psychotherapy group received items such as a colouring book, stress ball and head massager. <h2>Lifestyle therapies just as effective</h2> We found similar results in each program. At the trial’s beginning we gave each participant a score based on their self-reported mental health. We measured them again at the end of the program. Over eight weeks, those scores showed symptoms of depression reduced for participants in the lifestyle program (42%) and the psychotherapy program (37%). That difference was not statistically or clinically meaningful so we could conclude both treatments were as good as each other. There were some differences between groups. People in the lifestyle program improved their diet, while those in the psychotherapy program felt they had increased their social support – meaning how connected they felt to other people – compared to at the start of the treatment. Participants in both programs increased their physical activity. While this was expected for those in the lifestyle program, it was less expected for those in the psychotherapy program. It may be because they knew they were enrolled in a research study about lifestyle and subconsciously changed their activity patterns, or it could be a positive by-product of doing psychotherapy. There was also not much difference in cost. The lifestyle program was slightly cheaper to deliver: A$482 per participant, versus $503 for psychotherapy. That’s because hourly rates differ between dietitians and exercise physiologists, and psychologists. <h2>What does this mean for mental health workforce shortages?</h2> Demand for mental health services is increasing in Australia, while at the same time the workforce <a href="https://www.health.gov.au/sites/default/files/2023-10/national-mental-health-workforce-strategy-2022-2032.pdf">faces worsening nation-wide shortages</a>. Psychologists, who provide <a href="https://www.aihw.gov.au/getmedia/6b19e493-0ebe-420f-a9a3-e48b26aace9f/aihw-aus-249-ib.pdf?v=20240628145747&inline=true">about half</a> of all mental health services, can have long wait times. Our results suggest that, with the appropriate training and guidelines, allied health professionals who specialise in diet and exercise could help address this gap. Lifestyle therapies can be combined with psychology sessions for multi-disciplinary care. But diet and exercise therapies could prove particularly effective for those on waitlists to see a psychologists, who may be receiving no other professional support while they wait. Many dietitians and exercise physiologists already have advanced skills and expertise in motivating behaviour change. Most accredited practising dietitians are trained in managing <a href="https://link.springer.com/content/pdf/10.1007/978-3-030-67929-3_38-1.pdf">eating disorders</a> or <a href="https://www.nature.com/articles/s41572-020-0200-2">gastrointestinal conditions</a>, which commonly overlap with depression. There is also a cost argument. It is <a href="https://journals.sagepub.com/doi/full/10.1177/1355819616668202">overall cheaper</a> to train a dietitian ($153,039) than a psychologist ($189,063) – and it takes less time. <h2>Potential barriers</h2> Australians with chronic conditions (such as diabetes) can access subsidised dietitian and exercise physiologist appointments under various Medicare treatment plans. Those with eating disorders can also access subsidised dietitian appointments. But mental health care plans for people with depression do not support subsidised sessions with dietitians or exercise physiologists, despite <a href="https://dietitiansaustralia.org.au/sites/default/files/2024-04/Dietitians%20Australia%20Mental%20Health%20Evidence%20Brief%202024.pdf">peak bodies</a> urging them to do so. Increased training, upskilling and Medicare subsidies would be needed to support dietitians and exercise physiologists to be involved in treating mental health issues. <a href="https://foodandmoodcentre.com.au/academy">Our training</a> and clinical <a href="https://www.tandfonline.com/doi/full/10.1080/15622975.2022.2112074">guidelines</a> are intended to help clinicians practising lifestyle-based mental health care within their scope of practice (activities a health care provider can undertake). <h2>Future directions</h2> Our trial took place during COVID lockdowns and examined people with at least mild symptoms of depression who did not necessarily have a mental disorder. We are seeking to replicate these findings and are now running <a href="https://foodandmoodcentre.com.au/projects/the-harmone-trial/">a study</a> open to Australians with mental health conditions such as major depression or bipolar disorder.

How to help your grandkids avoid the same food mistakes you made

For parents and grandparents, often the biggest challenge is knowing what foods you should provide for your children, particularly if you have a picky eater. I am a father, so I know firsthand how fussy children can be, even more so at the end of the day when they are feeling shattered. Many parents see mealtimes as an opportunity to fill ’em up and get ’em out, which teaches your child that food is all about being ‘fast’ and unintentionally promotes a set of food-related behaviours that research tells us leads to negative health outcomes. I realise that with the endless demands of modern life, mealtimes can feel like yet another repetitive chore to get through, but I’m going give it to you straight: you wouldn’t light up a cigarette in your child’s mouth, and you wouldn’t let your child drink a can of beer, because you know the damage that this does to them. Over time, processed Western food can be just as detrimental to a person’s health as a cigarette or beer. Saving time or placating children by giving them processed food will simply lead to a new generation that struggles with obesity, diabetes, heart disease and other underlying health concerns. Breaking out of these lifelong food habits and ways of thinking is hard to do, which is why so many people don’t. Dealing with fussy eating is one of the most significant – and stressful – challenges many parents face, leaving them frustrated and worried about their child's nutrition, development and health. But fussy eating is normal – in fact, all parents should expect their child to go through a fussy eating phase. The science of why children are fussy eaters The reason why children predominantly go through a period of fussy eating is basic biology – the roots of this behaviour can be traced back to our hunter-gatherer ancestors and their development of a range of physiological responses for survival. This included developing ‘food fussiness’ – a natural aversion to unfamiliar foods and bitter flavours – like vegetables – to avoid ingesting potential toxins. Additionally, as our hunter-gatherer ancestors often experienced extended periods of food scarcity, they learned to seek out and store high-energy, palatable foods found in nature that were also high in natural sugars, fat and protein, such as fruits, honey, meat and nuts, to avoid starvation. As well as offering the best ‘bang for buck’ calorie-wise, these foods also provided a natural high and sense of satisfaction, triggering the release of feel-good chemicals called endorphins and learning chemicals called dopamine, which enabled our ancestors to remember the pleasure associated with eating that food and trigger a response the next time they saw it. So, when your child pushes back on the vegetables, there’s an evolutionary reason why! Seven things you can do to overcome fussy eating Fortunately, there are some simple – but effective – things you can do to support introducing healthy foods to your child or grandchild and overcome fussy eating: 1. Never bribe or force them to eat everything on the plate. You may have been brought up to do this, but it is wrong advice. Forcing them to eat is only disrupting their appetite regulation; let them dictate how much they eat. 2. Involve your child in meal preparation and cooking. Getting your child’s assistance with food shopping and preparation tasks is guaranteed to make them curious about the meal they’ve helped create and more willing to taste it. 3. Eliminate mealtime distractions. Turning off the television and putting the devices away will make sure your child can focus on the important task of tasting and fully experiencing new foods. 4. Wind back the clock and gather everyone around the dinner table. We all know that kids closely observe and mimic their parents so the best way to overcome fussy eating is by showing enthusiasm for trying new foods and a positive attitude toward healthy eating. 5. Offer small portions. Serving new foods in smaller servings will ensure you don’t overwhelm your child with new tastes and allow them to let you know if they’d like more of what they’ve tasted. 6. Resist the urge to make another meal. While it’s tempting to offer an alternative when your child refuses a meal, it creates more problems than it solves, teaching fussy eaters they can get the foods they like by refusing to eat what’s been served. 7. Don’t use food as a reward or punishment. Every parent has been there – trading the promise of a yummy dessert for two more bites of beans – but this practice only creates unhealthy associations with healthy foods. Your children will learn from what you do and eat; this goes for all facets of life, but none more so than what is placed in front of them at the dining table. You hold the keys to your child’s food future. <img src="https://oversixtydev.blob.core.windows.net/media/2024/08/dr-nick-fuller.jpg" alt="" width="1280" height="720" /> Dr Nick Fuller, The University of Sydney and Royal Prince Alfred Hospital, and author of the new book <a href="https://www.penguin.com.au/books/healthy-parents-healthy-kids-9780143791119" target="_blank" rel="noopener">Healthy Parents, Healthy Kids</a>, published by Penguin Books.

Tastes from our past can spark memories, trigger pain or boost wellbeing. Here’s how to embrace food nostalgia

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/megan-lee-490875">Megan Lee</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a>; <a href="https://theconversation.com/profiles/doug-angus-1542552">Doug Angus</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a>, and <a href="https://theconversation.com/profiles/kate-simpson-1542551">Kate Simpson</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Have you ever tried to bring back fond memories by eating or drinking something unique to that time and place? It could be a Pina Colada that recalls an island holiday? Or a steaming bowl of pho just like the one you had in Vietnam? Perhaps eating a favourite dish reminds you of a lost loved one – like the sticky date pudding Nanna used to make? If you have, you have tapped into <a href="https://www.tandfonline.com/doi/full/10.1080/02699931.2022.2142525">food-evoked nostalgia</a>. As researchers, we are exploring how eating and drinking certain things from your past may be important for your mood and mental health. <h2>Bittersweet longing</h2> First named in 1688 by Swiss medical student, <a href="https://www.jstor.org/stable/44437799">Johannes Hoffer</a>, <a href="https://compass.onlinelibrary.wiley.com/doi/10.1111/spc3.12070">nostalgia</a> is that bittersweet, sentimental longing for the past. It is experienced <a href="https://journals.sagepub.com/doi/10.1111/j.1467-8721.2008.00595.x">universally</a> across different cultures and lifespans from childhood into older age. But nostalgia does not just involve positive or happy memories – we can also experience nostalgia for <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2F0022-3514.91.5.975">sad and unhappy moments</a> in our lives. In the <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2Femo0000817">short and long term</a>, nostalgia can positively impact our health by improving <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2Fa0025167">mood</a> and <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2Femo0000817">wellbeing</a>, fostering <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2Fa0017597">social connection</a> and increasing quality of life. It can also trigger feelings of <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2Femo0000817">loneliness or meaninglessness</a>. We can use nostalgia to <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2Fa0025167">turn around a negative mood</a> or enhance our sense of <a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2Femo0000817">self, meaning and positivity</a>. Research suggests nostalgia alters activity in the <a href="https://academic.oup.com/scan/article/17/12/1131/6585517">brain regions associated with reward processing</a> – the same areas involved when we seek and receive things we like. This could explain the <a href="https://www.sciencedirect.com/science/article/abs/pii/S2352250X22002445?via%3Dihub">positive feelings</a> it can bring. Nostalgia can also increase feelings of loneliness and sadness, particularly if the memories highlight dissatisfaction, grieving, loss, or wistful feelings for the past. This is likely due to activation of <a href="https://www.sciencedirect.com/science/article/pii/S2352250X22002445?casa_token=V31ORDWcsx4AAAAA:Vef9hiwUz9506f5PYGsXH-JxCcnsptQnVPNaAGares2xTU5JbKSHakwGpLxSRO2dNckrdFGubA">brain areas</a> such as the amygdala, responsible for processing emotions and the prefrontal cortex that helps us integrate feelings and memories and regulate emotion. <h2>How to get back there</h2> There are several ways we can <a href="https://psycnet.apa.org/fulltext/2006-20034-013.html">trigger</a> or tap into nostalgia. Conversations with family and friends who have shared experiences, unique objects like photos, and smells can <a href="https://www.sciencedirect.com/science/article/abs/pii/S2352250X23000076">transport us back</a> to old times or places. So can a favourite song or old TV show, reunions with former classmates, even social media <a href="https://www.theverge.com/2015/3/24/8284703/facebook-on-this-day-nostalgia-recap">posts and anniversaries</a>. What we eat and drink can trigger <a href="https://www.emerald.com/insight/content/doi/10.1108/QMR-06-2012-0027/full/html">food-evoked nostalgia</a>. For instance, when we think of something as “<a href="https://theconversation.com/health-check-why-do-we-crave-comfort-food-in-winter-118776">comfort food</a>”, there are likely elements of nostalgia at play. Foods you found comforting as a child can evoke memories of being cared for and nurtured by loved ones. The form of these foods and the stories we tell about them may have been handed down through generations. Food-evoked nostalgia can be very powerful because it engages multiple senses: taste, smell, texture, sight and sound. The sense of <a href="https://www.tandfonline.com/doi/full/10.1080/09658211.2013.876048?casa_token=wqShWbRXJaYAAAAA%3AqJabgHtEbPtEQp7qHnl7wOb527bpGxzIJ_JwQX8eAyq1IrM_HQFIng8ELAMyuoFoeZyiX1zeJTPf">smell</a> is closely linked to the limbic system in the brain responsible for emotion and memory making food-related memories particularly vivid and emotionally charged. But, food-evoked nostalgia can also give rise to <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/hpja.873">negative memories</a>, such as of being forced to eat a certain vegetable you disliked as a child, or a food eaten during a sad moment like a loved ones funeral. Understanding why these foods <a href="https://www.tandfonline.com/doi/full/10.1080/02699931.2022.2142525?casa_token=16kAPHUQTukAAAAA%3A9IDvre8yUT8UsuiR_ltsG-3qgE2sdkIFgcrdH3T5EYbVEP9JZwPcsbmsPLT6Kch5EFFs9RPsMTNn">evoke negative memories</a> could help us process and overcome some of our adult food aversions. Encountering these foods in a positive light may help us reframe the memory associated with them. <h2>What people told us about food and nostalgia</h2> Recently <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/hpja.873">we interviewed eight Australians</a> and asked them about their experiences with food-evoked nostalgia and the influence on their mood. We wanted to find out whether they experienced food-evoked nostalgia and if so, what foods triggered pleasant and unpleasant memories and feelings for them. They reported they could use foods that were linked to times in their past to manipulate and influence their mood. Common foods they described as particularly nostalgia triggering were homemade meals, foods from school camp, cultural and ethnic foods, childhood favourites, comfort foods, special treats and snacks they were allowed as children, and holiday or celebration foods. One participant commented: <blockquote> I guess part of this nostalgia is maybe […] The healing qualities that food has in mental wellbeing. I think food heals for us. </blockquote> Another explained <blockquote> I feel really happy, and I guess fortunate to have these kinds of foods that I can turn to, and they have these memories, and I love the feeling of nostalgia and reminiscing and things that remind me of good times. </blockquote> Understanding food-evoked nostalgia is valuable because it provides us with an insight into how our sensory experiences and emotions intertwine with our memories and identity. While we know a lot about how food triggers nostalgic memories, there is still much to learn about the specific brain areas involved and the differences in food-evoked nostalgia in different cultures. In the future we may be able to use the science behind food-evoked nostalgia to help people experiencing dementia to tap into lost memories or in psychological therapy to help people reframe negative experiences. So, if you are ever feeling a little down and want to improve your mood, consider turning to one of your favourite comfort foods that remind you of home, your loved ones or a holiday long ago. Transporting yourself back to those times could help turn things around.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/232826/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/megan-lee-490875">Megan Lee</a>, Senior Teaching Fellow, Psychology, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a>; <a href="https://theconversation.com/profiles/doug-angus-1542552">Doug Angus</a>, Assistant Professor of Psychology, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a>, and <a href="https://theconversation.com/profiles/kate-simpson-1542551">Kate Simpson</a>, Sessional academic, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Mind

Can you drink your fruit and vegetables? How does juice compare to the whole food?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/emma-beckett-22673">Emma Beckett</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Do you struggle to eat your fruits and vegetables? You are not alone. Less than 5% of Australians eat the recommended serves of fresh produce <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/dietary-behaviour/latest-release">each day</a> (with 44% eating enough fruit but only 6% eating the recommended vegetables). Adults <a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups">should aim to eat</a> at least five serves of vegetables (or roughly 375 grams) and two serves of fruit (about 300 grams) each day. Fruits and vegetables help keep us healthy because they have lots of nutrients (vitamins, minerals and fibre) and health-promoting bioactive compounds (substances not technically essential but which have health benefits) without having many calories. So, if you are having trouble <a href="https://theconversation.com/want-your-child-to-eat-more-veggies-talk-to-them-about-eating-the-rainbow-195563">eating the rainbow</a>, you might be wondering – is it OK to drink your fruits and vegetables instead in a juice or smoothie? Like everything in nutrition, the answer is all about context. <h2>It might help overcome barriers</h2> Common reasons for not eating enough fruits and vegetables are <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/1747-0080.12735">preferences, habits, perishability, cost, availability, time and poor cooking skills</a>. Drinking your fruits and vegetables in juices or smoothies can help overcome some of these barriers. <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/j.1467-3010.2009.01760.x">Juicing or blending</a> can help disguise tastes you don’t like, like bitterness in vegetables. And it can blitz imperfections such as bruises or soft spots. Preparation doesn’t take much skill or time, particularly if you just have to pour store-bought juice from the bottle. Treating for food safety and shipping time does change the make up of juices slightly, but unsweetened juices still remain significant sources of <a href="https://pubmed.ncbi.nlm.nih.gov/12403253/">nutrients</a> and <a href="https://www.emerald.com/insight/content/doi/10.1108/00070701111140089/full/html?fullSc=1">beneficial bioactives</a>. Juicing can <a href="https://academic.oup.com/nutritionreviews/advance-article-pdf/doi/10.1093/nutrit/nuz031/30096176/nuz031.pdf">extend shelf life</a> and reduce the cost of nutrients. In fact, when researchers looked at the density of nutrients relative to the costs of common foods, <a href="https://www.mdpi.com/1660-4601/18/11/5771">fruit juice was the top performer</a>. <h2>So, drinking my fruits and veggies counts as a serve, right?</h2> How juice is positioned in healthy eating recommendations is a bit confusing. The <a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups/fruit">Australian Dietary Guidelines</a> include 100% fruit juice with fruit but vegetable juice isn’t mentioned. This is likely because vegetable juices weren’t as common in 2013 when the guidelines were last revised. <a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups/fruit">The guidelines</a> also warn against having juice too often or in too high amounts. This appears to be based on the logic that juice is similar, but not quite as good as, whole fruit. Juice has lower levels of fibre compared to fruits, with fibre important for gut health, heart health and promoting feelings of fullness. Juice and smoothies also release the sugar from the fruit’s other structures, making them “free”. The <a href="https://www.who.int/publications-detail-redirect/9789241549028">World Health Organization recommends</a> we limit free sugars for good health. But fruit and vegetables are more than just the sum of their parts. When we take a “<a href="https://hal.science/hal-01630639/">reductionist</a>” approach to nutrition, foods and drinks are judged based on assumptions made about limited features such as sugar content or specific vitamins. But these features might not have the impact we logically assume because of the complexity of foods and people. When humans eat varied and complex diets, we don’t necessarily need to be concerned that some foods are lower in fibre than others. Juice can retain the nutrients and bioactive compounds of fruit and vegetables and even add more because parts of the fruit we don’t normally eat, like the skin, can be included. <h2>So, it is healthy then?</h2> A recent <a href="https://academic.oup.com/nutritionreviews/advance-article/doi/10.1093/nutrit/nuae036/7659479?login=false">umbrella review of meta-analyses</a> (<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8977198/">a type of research</a> that combines data from multiple studies of multiple outcomes into one paper looked at the relationship between 100% juice and a range of health outcomes. Most of the evidence showed juice had a neutral impact on health (meaning no impact) or a positive one. Pure 100% juice was linked to improved heart health and inflammatory markers and wasn’t clearly linked to weight gain, multiple cancer types or metabolic markers (such as blood sugar levels). Some health risks linked to drinking juice were <a href="https://academic.oup.com/nutritionreviews/advance-article/doi/10.1093/nutrit/nuae036/7659479?login=false">reported</a>: death from heart disease, prostate cancer and diabetes risk. But the risks were all reported in <a href="https://www.cancer.gov/research/participate/what-are-observational-studies#:%7E:text=Observational%20studies%20are%20research%20studies,over%20a%20period%20of%20time.">observational studies</a>, where researchers look at data from groups of people collected over time. These are not controlled and do not record consumption in the moment. So other drinks people think of as 100% fruit juice (such as sugar-sweetened juices or cordials) might accidentally be counted as 100% fruit juice. These types of studies are not good at showing the direct causes of illness or death. <h2>What about my teeth?</h2> The common belief juice damages teeth might not stack up. Studies that show juice damages teeth often <a href="https://www.frontiersin.org/articles/10.3389/fpubh.2019.00190/full">lump 100% juice in with sweetened drinks</a>. Or they use model systems like fake mouths that <a href="https://www.frontiersin.org/articles/10.3389/fpubh.2019.00190/full">don’t match</a> how people drinks juice in real life. Some <a href="https://www.frontiersin.org/journals/public-health/articles/10.3389/fpubh.2019.00190/full">use extreme scenarios</a> like sipping on large volumes of drink frequently over long periods of time. Juice is acidic and does contain sugars, but it is possible proper oral hygiene, including <a href="https://www.sciencedirect.com/science/article/abs/pii/S0300571207000152?via%3Dihub">rinsing, cleaning</a> and using straws can mitigate these risks. Again, reducing juice to its acid level misses the rest of the story, including the nutrients and bioactives contained in juice that are <a href="https://www.sciencedirect.com/science/article/pii/S2352385919300210#:%7E:text=Research%20has%20also%20confirmed%20that,prevention%20of%20oral%20inflammatory%20disorders.">beneficial to oral health</a>. <h2>So, what should I do?</h2> Comparing whole fruit (a food) to juice (a drink) can be problematic. They serve different culinary purposes, so aren’t really interchangeable. The Australian Guide to Healthy Eating recommends <a href="https://www.eatforhealth.gov.au/guidelines/australian-guide-healthy-eating">water as the preferred beverage</a> but this assumes you are getting all your essential nutrients from eating. Where juice fits in your diet depends on what you are eating and what other drinks it is replacing. Juice might replace water in the context of a “perfect” diet. Or juice might replace <a href="https://www.cambridge.org/core/journals/public-health-nutrition/article/substitution-of-pure-fruit-juice-for-fruit-and-sugarsweetened-beverages-and-cardiometabolic-risk-in-epicnl-a-prospective-cohort-study/B7314F1198109712DE0F2E44D919A6A7">alcohol or sugary soft drinks</a> and make the relative benefits look very different. <h2>On balance</h2> Whether you want to eat your fruits and vegetables or drink them comes down to what works for you, how it fits into the context of your diet and your life. Smoothies and juices aren’t a silver bullet, and there is no evidence they work as a “cleanse” or <a href="https://theconversation.com/lemon-water-wont-detox-or-energise-you-but-it-may-affect-your-body-in-other-ways-180035">detox</a>. But, with society’s low levels of fruit and vegetable eating, having the option to access nutrients and bioactives in a cheap, easy and tasty way shouldn’t be discouraged either.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/205222/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/emma-beckett-22673">Emma Beckett</a>, Adjunct Senior Lecturer, Nutrition, Dietetics & Food Innovation - School of Health Sciences, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Food & Wine

Why doesn’t water help with spicy food? What about milk or beer?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/daniel-eldridge-1494633">Daniel Eldridge</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> Spicy foods taste spicy because they contain a family of compounds called capsaicinoids. Capsaicin is the major culprit. It’s found in chillies, jalapeños, cayenne pepper, and is even the active ingredient in <a href="https://pubmed.ncbi.nlm.nih.gov/31334983/">pepper spray</a>. Capsaicin doesn’t actually physically heat up your mouth. The burning sensation comes from receptors in the mouth reacting to capsaicin and sending a signal to the brain that something is very hot. That’s why the “hot” chilli sensation feels so real – we even respond by sweating. To alleviate the heat, you need to remove the capsaicin from your mouth. So why doesn’t drinking water help make that spicy feeling go away? And what would work better instead? <h2>Water-loving and water-hating molecules</h2> To help us choose what might wash the capsaicin away most effectively, it’s helpful to know that capsaicin is a hydrophobic molecule. That means it hates being in contact with water and will not easily mix with it. Look what happens when you try to mix hydrophobic sand with water. <figure><iframe src="https://www.youtube.com/embed/H8cj9CpHW7w?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> On the other hand, hydrophilic molecules love water and are very happy to mix with it. You’ve likely seen this before. You can easily dissolve hydrophilic sugar in water, but it’s hard to wash away hydrophobic oils from your pan using tap water alone. If you try to wash hydrophobic capsaicin away with water, it won’t be very effective, because hydrophilic and hydrophobic substances don’t mix. Going for iced water will be even less effective, as hydrophobic capsaicin is even less soluble in water at lower temperatures. You may get a temporary sense of relief while the cold liquid is in your mouth, but as soon as you swallow it, you’ll be back where you started. Instead, a good choice would be to consume something that is also hydrophobic. This is because of an old-but-true adage in chemistry that “like dissolves like”. The idea is that generally, hydrophobic substances will not dissolve in something hydrophilic – like water – but will dissolve in something that is also hydrophobic, as this video shows: <figure><iframe src="https://www.youtube.com/embed/s5yfs-Pr_y8?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>My mouth is on fire. What should I drink instead of water?</h2> A swig of oil would likely be effective, but is perhaps not so palatable. Milk makes for an ideal choice for two reasons. The first is that milk contains hydrophobic fats, which the capsaicin will more easily dissolve in, allowing it to be washed away. The second is that dairy products contain a protein called casein. Casein is an emulsifier, a substance that helps oils and water mix, as in this video: <figure><iframe src="https://www.youtube.com/embed/S4XeQhZRLDE?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> Casein plays a large role in keeping the fat mixed throughout your glass of milk, and it also has a strong affinity for capsaicin. It will readily wrap up and encapsulate capsaicin molecules and assist in carrying them away from the receptor. This relieves the <a href="https://pubmed.ncbi.nlm.nih.gov/36510373/">burning sensation</a>. <h2>OK but I hate drinking milk. What else can I try?</h2> What about raita? This dish, commonly served with Indian curries, is made primarily from yoghurt. So aside from being its own culinary experience, raita is rich in fats, and therefore contains plenty of hydrophobic material. It also contains casein, which will again help lock up and remove the capsaicin. Ice cream would also work, as it contains both casein and large amounts of hydrophobic substances. Some studies have also shown that consuming <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9328490/">drinks with large amounts of sugar</a> can relieve spiciness. What about reaching for that ice cold beer? This is commonly suggested as a suitable approach to stop the burning. At first glance, this may seem a good idea because capsaicin is highly soluble in alcohol. However, most beers only contain between 4–6% alcohol. The bulk of the liquid in beer is water, which is hydrophilic and cannot wash away capsaicin. The small amount of alcohol in your beer would make it slightly more effective, but not to any great degree. Your curry and beer may taste great together, but that’s likely the only benefit. In truth, an alcoholic beverage is not going to help much unless you go for something with a much, much higher alcohol content, which comes with its own problems.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/226624/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/daniel-eldridge-1494633">Daniel Eldridge</a>, Senior Lecturer in Chemistry, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Food & Wine

The voice in your head may help you recall and process words. But what if you don’t have one?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/derek-arnold-106381">Derek Arnold</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Can you imagine hearing yourself speak? A voice inside your head – perhaps reciting a shopping list or a phone number? What would life be like if you couldn’t? Some people, including me, cannot have imagined visual experiences. We cannot close our eyes and conjure an experience of seeing a loved one’s face, or imagine our lounge room layout – to consider if a new piece of furniture might fit in it. This is called “<a href="https://theconversation.com/a-blind-and-deaf-mind-what-its-like-to-have-no-visual-imagination-or-inner-voice-226134">aphantasia</a>”, from a Greek phrase where the “a” means without, and “phantasia” refers to an image. Colloquially, people like myself are often referred to as having a “blind mind”. While most attention has been given to the inability to have imagined visual sensations, aphantasics can lack other imagined experiences. We might be unable to experience imagined tastes or smells. Some people cannot imagine hearing themselves speak. A <a href="https://www.sciencealert.com/we-used-to-think-everybody-heard-a-voice-inside-their-heads-but-we-were-wrong">recent study</a> has advanced our understanding of people who cannot imagine hearing their own internal monologue. Importantly, the authors have identified some tasks that such people are more likely to find challenging. <h2>What the study found</h2> Researchers at the University of Copenhagen in Denmark and at the University of Wisconsin-Madison in the United States <a href="https://journals.sagepub.com/doi/10.1177/09567976241243004">recruited 93 volunteers</a>. They included 46 adults who reported low levels of inner speech and 47 who reported high levels. Both groups were given challenging tasks: judging if the names of objects they had seen would rhyme and recalling words. The group without an inner monologue performed worse. But differences disappeared when everyone could say words aloud. Importantly, people who reported less inner speech were not worse at all tasks. They could recall similar numbers of words when the words had a different appearance to one another. This negates any suggestion that aphants (people with aphantasia) simply weren’t trying or were less capable. <h2>A welcome validation</h2> The study provides some welcome evidence for the lived experiences of some aphants, who are still often told their experiences are not different, but rather that they cannot describe their imagined experiences. Some people feel anxiety when they realise other people can have imagined experiences that they cannot. These feelings may be deepened when others assert they are merely confused or inarticulate. In my own <a href="https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2024.1374349/full">aphantasia research</a> I have often quizzed crowds of people on their capacity to have imagined experiences. Questions about the capacity to have imagined visual or audio sensations tend to be excitedly endorsed by a vast majority, but questions about imagined experiences of taste or smell seem to cause more confusion. Some people are adamant they can do this, including a colleague who says he can imagine what combinations of ingredients will taste like when cooked together. But other responses suggest subtypes of aphantasia may prove to be more common than we realise. The authors of the recent study suggest the inability to imagine hearing yourself speak should be referred to as “anendophasia”, meaning without inner speech. Other authors had suggested <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8551557/">anauralia</a> (meaning without auditory imagery). Still other researchers have referred to all types of imagined sensation as being different types of “imagery”. Having <a href="https://www.sciencedirect.com/science/article/abs/pii/S0010945222000417">consistent names</a> is important. It can help scientists “talk” to one another to compare findings. If different authors use different names, important evidence can be missed. <h2>We have more than 5 senses</h2> Debate continues about how many senses humans have, but some scientists reasonably argue for a <a href="https://www.sensorytrust.org.uk/blog/how-many-senses-do-we-have#:%7E:text=Because%20there%20is%20some%20overlap,sensation%20of%20hunger%20or%20thirst.">number greater than 20</a>. In addition to the five senses of sight, smell, taste, touch and hearing, lesser known senses include thermoception (our sense of heat) and proprioception (awareness of the positions of our body parts). Thanks to proprioception, most of us can close our eyes and touch the tip of our index finger to our nose. Thanks to our vestibular sense, we typically have a good idea of which way is up and can maintain balance. It may be tempting to give a new name to each inability to have a given type of imagined sensation. But this could lead to confusion. Another approach would be to adapt phrases that are already widely used. People who are unable to have imagined sensations commonly refer to ourselves as “aphants”. This could be adapted with a prefix, such as “audio aphant”. Time will tell which approach is adopted by most researchers. <h2>Why we should keep investigating</h2> Regardless of the names we use, the study of multiple types of inability to have an imagined sensation is important. These investigations could reveal the essential processes in human brains that bring about a conscious experience of an imagined sensation. In time, this will not only lead to a better understanding of the diversity of humans, but may help uncover how human brains can create any conscious sensation. This question – how and where our conscious feelings are generated – remains one of the great mysteries of science.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/230973/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/derek-arnold-106381">Derek Arnold</a>, Professor, School of Psychology, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Want to reduce your dementia risk? Eat these 4 foods, says new study

If you are what you eat, this might make you hungrier for foods that are bright in every sense. Research has shown that living, vibrant foods can slow down aging at a cellular level; while fruit and vegetables in particular have been associated with lower incidence of cognitive decline as individuals age. However, research has been relatively lacking on just how much of these brain-healthy foods you really need and which fruit and vegetables are best for the job. In collaboration with public health experts at Harvard University, medical researchers at China’s Zhejiang University School of Medicine conducted a meta-analysis that’s slated to be published in the June 2024 issue of The Journal of Nutrition, Health, and Aging. They combined data from two large-scale population-representative studies that analysed the diets and cognitive function of more than 10,000 participants ages 55 and older from China and the US. <h2>What daily diets revealed</h2> The data included diet questionnaires that honed in on the average of participants’ total daily intake of several different types of foods, including fruit and vegetables, and also broke them down into sub-types like green leafy vegetables and berries. Over a period of five years, the participants also took part in activities designed to assess their cognitive function and the average rate of cognitive decline. Overall, participants who included the most fruit and vegetables in their daily diets performed best on the brain tests and maintained those results over time. This suggested that both fruit and vegetables had protective elements that slowed cognitive decline. <h2>Vegetables that help protect cognition</h2> Interestingly, certain types of vegetables appeared to be more beneficial than others—say the researchers: “Our findings support the potential beneficial roles of VF, especially cruciferous vegetables, green leafy vegetables, and red and yellow vegetables, in maintaining cognitive function and slowing cognitive decline in middle-aged and older adults.” The researchers pointed to several reasons these particular vegetables might have shown a substantial impact, including anti-inflammatory and antioxidation nutrients like flavonoids and various vitamins or even gut improvements that have been shown to help improve or protect cognition. While beans didn’t figure prominently in both studies, they showed a protective element in the US study, so they are also worth keeping on your plate. (Beans are also thought to be one of the top foods for longevity.) <h2>Fruit that pack a punch</h2> As for fruit, while some didn’t show as much of a protective effect across the board, berries and apples are two examples of fruit that experts have previously said provide major polyphenol and antioxidant effect. Participants whose brains maintained performance were shown to have eaten three or more servings of vegetables and two or more servings of fruit per day. This is on par with the five servings of vegetables and two servings of fruit recommended we eat every day.

Queen Mary’s wedding dressmaker reveals process behind iconic gown

The Danish designer and dressmaker who designed Queen Mary’s wedding gown has recalled the “rather terrifying” process of making the iconic dress. Birgit Hallstein created the custom gown for the Aussie-born royal for her to marry Prince Frederik in 2004, as the designer recalled having to adhere to an unusual royal tradition when creating the dress. Hallstein said that she put the finishing touches on the dress on the wedding day: a decision that was mentioned to her by Mary's new mother-in-law, Queen Margrethe. Hallstein admits the old tradition, which involves doing the final loops and stitches the morning of the wedding, also helped her process in the long run. "[It] was a thing I did because it's a tradition in some families, but honestly I don't remember if Queen Margrethe would have mentioned such a thing," Hallstein told <a href="https://style.nine.com.au/latest/queen-mary-of-denmark-20th-wedding-anniversary-wedding-dressmaker-birgit-hallstein-interview/9f0c57eb-2d7b-44fd-ae0b-487d1b3592a5">9Honey</a>. "Maybe, because she knows a lot of those things... I am sure we talked about it, but anyway it was practical to gather the dress on the day because it's big." The process for Hallstein began in November 2003, as she admitted it was the most important garment she had ever worked on. "It was rather terrifying," she admitted with a laugh. "It's a bit like an exam, just a really big one, because if you fail everyone will see." Hallstein worked in a dedicated space at Amalienborg Palace to deliver the gown as well as the outfits worn by the bridesmaids, page boys and flower girls. "The sewing took hundreds of hours, starting in January 2004 and ending right before the wedding," she recalled. There was also the added pressure of adhering to royal traditions and protocols around the use of the antique veil and the lace attachment to the petticoat, which was from Queen Margrethe's private collection. "There are rules to follow, [you're] not allowed to cut in it and only skilled repairs [are allowed]," Hallstein said. "I had to hide around two or three metres of the antique lace in between layers of organza inside the dress to make sure it was not damaged by high heels, chairs, cars and carriages during the day." In a social media post to mark 20 years since the world got their first look at the classic gown, the dressmaker explained to fans that "the wedding gown consists of three parts". “There's a big tulle petticoat, edged with almost 60 yards of Chantilly lace, on this a big light blue silk bow were placed, to make sure the first born would be a son," she said.

4 foods that ease heartburn

Heartburn, acid reflux, GORD… whatever you want to call it, it’s not a pleasant thing to experience. Yet hundreds of thousands of us around the country suffer from heartburn each year. And while medication may be the solution for some, it’s not always the most effective option. So, you’ll be happy to learn that what you eat may ease your symptoms. Here are four of the best foods for heartburn. 1. Papaya Papain, an enzyme found in papaya, has been proven to aid in digestion. In addition, the fibre content and proteolytic enzymes are a great source of short-chain fatty acids, which <a href="https://www.ideals.illinois.edu/handle/2142/29416" target="_blank" rel="noopener">a recent study</a> described as “the most important product of fermentation”, and an essential part of improving gut health. 2. Aloe vera juice Aloe vera does much more than just ease sunburn or skin irritations – it’s been used to help ease constipation and treat type 2 diabetes and gastrointestinal disorders for centuries. “Its anti-inflammatory properties have been suggested to ease inflammation in the oesophagus caused by reflux,” Maria Bella, author of The Complete Idiot’s Guide to the Acid Reflux Diet, tells <a href="http://www.goodhousekeeping.com/health/diet-nutrition/g4536/best-foods-for-acid-reflux/" target="_blank" rel="noopener">Good Housekeeping</a>. 3. Banana Because of its low acidity, bananas are great for gastrointestinal discomfort, but they’re particularly good for heartburn as they can stick to the irritated oesophageal lining. “It forms a protective film that coats, protects and soothes,” digestive health expert Dr Gerard E. Mullin explains to <a href="http://www.prevention.com/food/foods-soothe-heartburn" target="_blank" rel="noopener">Prevention</a>. 4. Cinnamon gum By producing saliva, gum helps neutralise stomach acid. “It also leads to more frequent swallowing, which can move the irritating acid down the oesophagus more quickly,” Maria Bella says. Mint can make your symptoms worse, however, so stick to cinnamon, which <a href="http://www.ncbi.nlm.nih.gov/pubmed/20924865" target="_blank" rel="noopener">studies show</a> may have anti-inflammatory properties.

Not all ultra-processed foods are bad for your health, whatever you might have heard

But new evidence published <a href="https://www.bmj.com/content/385/bmj-2023-078476">this week</a> found not all “ultra-processed” foods are linked to poor health. That includes the mass-produced wholegrain bread you buy from the supermarket. While this newly published research and associated <a href="https://www.bmj.com/content/385/bmj.q793">editorial</a> are unlikely to end the wrangling about how best to define unhealthy foods and diets, it’s critical those debates don’t delay the implementation of policies that are likely to actually improve our diets. <h2>What are ultra-processed foods?</h2> <a href="https://pubmed.ncbi.nlm.nih.gov/30744710/">Ultra-processed foods</a> are industrially produced using a variety of processing techniques. They typically include ingredients that can’t be found in a home kitchen, such as preservatives, emulsifiers, sweeteners and/or artificial colours. Common examples of ultra-processed foods include packaged chips, flavoured yoghurts, soft drinks, sausages and mass-produced packaged wholegrain bread. In <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7719194/#CR13">many other countries</a>, ultra-processed foods make up a large proportion of what people eat. A <a href="https://pubmed.ncbi.nlm.nih.gov/31676952/">recent study</a> estimated they make up an average of 42% of total energy intake in Australia. <h2>How do ultra-processed foods affect our health?</h2> Previous <a href="https://pubmed.ncbi.nlm.nih.gov/33167080/">studies</a> have linked increased consumption of ultra-processed food with poorer health. High consumption of ultra-processed food, for example, has been associated with a <a href="https://pubmed.ncbi.nlm.nih.gov/38418082/">higher risk</a> of type 2 diabetes, and death from heart disease and stroke. Ultra-processed foods are typically high in energy, added sugars, salt and/or unhealthy fats. These have long been <a href="https://www.who.int/news-room/fact-sheets/detail/healthy-diet">recognised</a> as risk factors for a range of diseases. It has also been suggested that structural changes that happen to ultra-processed foods as part of the manufacturing process <a href="https://pubmed.ncbi.nlm.nih.gov/31105044/">may</a> lead you to eat more than you should. Potential explanations are that, due to the way they’re made, the foods are quicker to eat and more palatable. It’s also <a href="https://pubmed.ncbi.nlm.nih.gov/35952706/">possible</a> certain food additives may impair normal body functions, such as the way our cells reproduce. <h2>Is it harmful? It depends on the food’s nutrients</h2> The <a href="https://www.bmj.com/content/385/bmj-2023-078476">new paper</a> just published used 30 years of data from two large US cohort studies to evaluate the relationship between ultra-processed food consumption and long-term health. The study tried to disentangle the effects of the manufacturing process itself from the nutrient profile of foods. The study found a small increase in the risk of early death with higher ultra-processed food consumption. But importantly, the authors also looked at diet quality. They found that for people who had high quality diets (high in fruit, vegetables, wholegrains, as well as healthy fats, and low in sugary drinks, salt, and red and processed meat), there was no clear association between the amount of ultra-processed food they ate and risk of premature death. This suggests overall diet quality has a stronger influence on long-term health than ultra-processed food consumption. When the researchers analysed ultra-processed foods by sub-category, mass-produced wholegrain products, such as supermarket wholegrain breads and wholegrain breakfast cereals, were not associated with poorer health. This finding matches another recent <a href="https://pubmed.ncbi.nlm.nih.gov/38417577/">study</a> that suggests ultra-processed wholegrain foods are not a driver of poor health. The authors concluded, while there was some support for limiting consumption of certain types of ultra-processed food for long-term health, not all ultra-processed food products should be universally restricted. <h2>Should dietary guidelines advise against ultra-processed foods?</h2> Existing national <a href="https://www.eatforhealth.gov.au/sites/default/files/2022-09/n55_australian_dietary_guidelines.pdf">dietary</a> <a href="https://www.health.govt.nz/system/files/documents/publications/eating-activity-guidelines-new-zealand-adults-updated-2020-oct22.pdf">guidelines</a> have been developed and refined based on decades of nutrition evidence. Much of the recent evidence related to ultra-processed foods tells us what we already knew: that products like soft drinks, alcohol and processed meats are bad for health. Dietary guidelines <a href="https://pubmed.ncbi.nlm.nih.gov/35184508/">generally</a> already advise to eat mostly whole foods and to limit consumption of highly processed foods that are high in refined grains, saturated fat, sugar and salt. But some nutrition researchers have <a href="https://www.bmj.com/content/384/bmj.q439">called</a> for dietary guidelines to be amended to recommend avoiding ultra-processed foods. Based on the available evidence, it would be difficult to justify adding a sweeping statement about avoiding all ultra-processed foods. Advice to avoid all ultra-processed foods would likely unfairly impact people on low-incomes, as many ultra-processed foods, such as supermarket breads, are relatively affordable and convenient. Wholegrain breads also provide important nutrients, such as fibre. In many countries, bread is the <a href="https://www.health.govt.nz/system/files/documents/publications/a-focus-on-nutrition-ch3_0.pdf">biggest contributor</a> to fibre intake. So it would be problematic to recommend avoiding supermarket wholegrain bread just because it’s ultra-processed. <h2>So how can we improve our diets?</h2> There is strong <a href="https://www.foodpolicyindex.org.au/_files/ugd/7ee332_a2fa1694e42f423195caf581044fccf1.pdf">consensus</a> on the need to implement evidence-based policies to improve population diets. This includes legislation to restrict children’s exposure to the marketing of unhealthy foods and brands, mandatory Health Star Rating nutrition labelling and taxes on sugary drinks. These policies are underpinned by <a href="https://pubmed.ncbi.nlm.nih.gov/37659696/">well-established systems</a> for classifying the healthiness of foods. If new evidence unfolds about mechanisms by which ultra-processed foods drive health harms, these classification systems can be updated to reflect such evidence. If specific additives are found to be harmful to health, for example, this evidence can be incorporated into existing nutrient profiling systems, such as the <a href="http://www.healthstarrating.gov.au/internet/healthstarrating/publishing.nsf/content/home">Health Star Rating</a> food labelling scheme. Accordingly, policymakers can confidently progress food policy implementation using the tools for classifying the healthiness of foods that we already have. Unhealthy diets and obesity are among the <a href="https://www.aihw.gov.au/reports/burden-of-disease/burden-of-disease-study-2018-key-findings/contents/key-findings">largest contributors</a> to poor health. We can’t let the hype and academic debate around “ultra-processed” foods delay implementation of globally recommended policies for improving population diets.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/229493/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/gary-sacks-3957">Gary Sacks</a>, Professor of Public Health Policy, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/kathryn-backholer-10739">Kathryn Backholer</a>, Co-Director, Global Centre for Preventive Health and Nutrition, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/kathryn-bradbury-1532662">Kathryn Bradbury</a>, Senior Research Fellow in the School of Population Health, <a href="https://theconversation.com/institutions/university-of-auckland-waipapa-taumata-rau-1305">University of Auckland, Waipapa Taumata Rau</a>, and <a href="https://theconversation.com/profiles/sally-mackay-1532685">Sally Mackay</a>, Senior Lecturer Epidemiology and Biostatistics, <a href="https://theconversation.com/institutions/university-of-auckland-waipapa-taumata-rau-1305">University of Auckland, Waipapa Taumata Rau</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Yes, adults can develop food allergies. Here are 4 types you need to know about

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/clare-collins-7316">Clare Collins</a>, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a> If you didn’t have food allergies as a child, is it possible to develop them as an adult? The short answer is yes. But the reasons why are much more complicated. Preschoolers are about <a href="https://pubmed.ncbi.nlm.nih.gov/25316115/">four times more likely to have a food allergy</a> than adults and are more likely to grow out of it as they get older. It’s hard to get accurate figures on adult food allergy prevalence. The Australian National Allergy Council reports <a href="https://nationalallergycouncil.org.au/about-us/our-strategy">one in 50 adults</a> have food allergies. But a US survey suggested as many as <a href="https://pubmed.ncbi.nlm.nih.gov/30646188/">one in ten adults</a> were allergic to at least one food, with some developing allergies in adulthood. <h2>What is a food allergy</h2> <a href="https://pubmed.ncbi.nlm.nih.gov/36509408/">Food allergies</a> are immune reactions involving <a href="https://www.aaaai.org/tools-for-the-public/allergy,-asthma-immunology-glossary/immunoglobulin-e-(ige)-defined">immunoglobulin E (IgE)</a> – an antibody that’s central to triggering allergic responses. These are known as “IgE-mediated food allergies”. Food allergy symptoms that are not mediated by IgE are usually delayed reactions and called <a href="https://pubmed.ncbi.nlm.nih.gov/25316115/">food intolerances or hypersensitivity</a>. Food allergy symptoms can include hives, swelling, difficulty swallowing, vomiting, throat or chest tightening, trouble breathing, chest pain, rapid heart rate, dizziness, low blood pressure or <a href="https://www.allergy.org.au/hp/papers/acute-management-of-anaphylaxis-guidelines?highlight=WyJhbmFwaHlsYXhpcyJd">anaphylaxis</a>. IgE-mediated food allergies can be life threatening, so all adults need an <a href="https://allergyfacts.org.au/allergy-management/newly-diagnosed/action-plan-essentials">action management plan</a> developed in consultation with their medical team. Here are four IgE-mediated food allergies that can occur in adults – from relatively common ones to rare allergies you’ve probably never heard of. <h2>1. Single food allergies</h2> The most <a href="https://pubmed.ncbi.nlm.nih.gov/30646188/">common IgE-mediated food allergies</a> in adults in a US survey were to: <ul> <li>shellfish (2.9%)</li> <li>cow’s milk (1.9%)</li> <li>peanut (1.8%)</li> <li>tree nuts (1.2%)</li> <li>fin fish (0.9%) like barramundi, snapper, salmon, cod and perch.</li> </ul> In these adults, about 45% reported reacting to multiple foods. This compares to <a href="https://pubmed.ncbi.nlm.nih.gov/25316115/">most common childhood food allergies</a>: cow’s milk, egg, peanut and soy. Overall, adult food allergy prevalence appears to be increasing. Compared to <a href="https://pubmed.ncbi.nlm.nih.gov/14657884/">older surveys published in 2003</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/15241360/">2004</a>, peanut allergy prevalence has increased about three-fold (from 0.6%), while tree nuts and fin fish roughly doubled (from 0.5% each), with shellfish similar (2.5%). While new <a href="https://pubmed.ncbi.nlm.nih.gov/38214821/">adult-onset food allergies are increasing</a>, childhood-onset food allergies are also more likely to be retained into adulthood. Possible reasons for both <a href="https://pubmed.ncbi.nlm.nih.gov/38214821/">include</a> low vitamin D status, lack of immune system challenges due to being overly “clean”, heightened sensitisation due to allergen avoidance, and more frequent antibiotic use. <h2>2. Tick-meat allergy</h2> Tick-meat allergy, also called α-Gal syndrome or mammalian meat allergy, is an allergic reaction to galactose-alpha-1,3-galactose, or α-Gal for short. <a href="https://pubmed.ncbi.nlm.nih.gov/33529984/">Australian immunologists first reported</a> links between α-Gal syndrome and tick bites in 2009, with cases also reported in the United States, Japan, Europe and South Africa. The <a href="https://pubmed.ncbi.nlm.nih.gov/38318181/">US Centers for Disease Control estimates</a> about 450,000 Americans <a href="https://www.cdc.gov/mmwr/volumes/72/wr/mm7230a2.htm">could be affected</a>. The α-Gal contains a carbohydrate molecule that is bound to a <a href="https://pubmed.ncbi.nlm.nih.gov/38318181/">protein</a> molecule in <a href="https://alphagalinformation.org/what-is-a-mammal/">mammals</a>. The IgE-mediated allergy is triggered after repeated bites from ticks or <a href="https://www.insectshield.com/pages/chiggers">chigger mites</a> that have bitten those mammals. When tick saliva crosses into your body through the bite, antibodies to α-Gal are produced. When you subsequently eat foods that contain α-Gal, the allergy is triggered. These triggering foods include meat (lamb, beef, pork, rabbit, kangaroo), dairy products (yoghurt, cheese, ice-cream, cream), <a href="https://en.wikipedia.org/wiki/Gelatin">animal-origin gelatin</a> added to gummy foods (jelly, lollies, marshmallow), prescription medications and over-the counter supplements containing gelatin (<a href="https://www.drugs.com/inactive/gelatin-57.html">some antibiotics, vitamins and other supplements</a>). Tick-meat allergy reactions can be hard to recognise because they’re usually delayed, and they can be severe and include anaphylaxis. Allergy <a href="https://www.allergy.org.au/patients/food-allergy/mammalian-meat-tick-faq">organisations produce management guidelines</a>, so always discuss management with your doctor. <h2>3. Fruit-pollen allergy</h2> Fruit-pollen allergy, called pollen food allergy syndrome, is an <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">IgE-mediated allergic reaction</a>. In susceptible adults, pollen in the air provokes the production of IgE antibodies to antigens in the pollen, but these antigens are similar to ones found in some fruits, vegetables and herbs. The problem is that <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">eating those plants</a> triggers an allergic reaction. The <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">most allergenic tree pollens</a> are from birch, cypress, Japanese cedar, <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/latex-allergy">latex</a>, grass, and ragweed. Their pollen can cross-react with <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">fruit and vegetables</a>, including kiwi, banana, mango, avocado, grapes, celery, carrot and potato, and some herbs such as caraway, coriander, fennel, pepper and paprika. Fruit-pollen allergy is not common. Prevalence <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">estimates are between 0.03% and 8%</a> depending on the country, but it can be life-threatening. Reactions range from itching or tingling of lips, mouth, tongue and throat, called <a href="https://pubmed.ncbi.nlm.nih.gov/20306812/">oral allergy syndrome</a>, to mild <a href="https://www.allergy.org.au/patients/skin-allergy/urticaria-hives">hives</a>, to anaphylaxis. <h2>4. Food-dependent, exercise-induced food allergy</h2> During heavy exercise, the stomach produces less acid than usual and gut permeability increases, meaning that small molecules in your gut are more likely to escape across the membrane into your blood. These include food molecules that trigger an IgE reaction. If the person already has IgE antibodies to the foods eaten before exercise, then the risk of triggering food allergy reactions is increased. This allergy is called <a href="https://pubmed.ncbi.nlm.nih.gov/37893663/">food-dependent exercise-induced allergy</a>, with symptoms ranging from hives and swelling, to difficulty breathing and anaphylaxis. <a href="https://pubmed.ncbi.nlm.nih.gov/30601082/">Common trigger foods include</a> wheat, seafood, meat, poultry, egg, milk, nuts, grapes, celery and other foods, which could have been eaten many hours before exercising. To complicate things even further, allergic <a href="https://pubmed.ncbi.nlm.nih.gov/33181008/">reactions can</a> occur at lower levels of trigger-food exposure, and be more severe if the person is simultaneously taking non-steroidal inflammatory medications like aspirin, drinking alcohol or is sleep-deprived. Food-dependent exercise-induced allergy is extremely rare. Surveys have estimated prevalence as between <a href="https://www.sciencedirect.com/science/article/pii/S1555415517300259">one to 17 cases per 1,000 people worldwide</a> with the highest prevalence between the teenage years to age 35. Those affected often have other allergic conditions such as hay fever, asthma, allergic conjunctivitis and dermatitis. <h2>Allergies are a growing burden</h2> The <a href="https://pubmed.ncbi.nlm.nih.gov/36509408/">burden on physical health, psychological health</a> and health costs due to food allergy is increasing. In the US, this <a href="https://pubmed.ncbi.nlm.nih.gov/38393624/">financial burden was estimated as $24 billion per year</a>. Adult food allergy needs to be taken seriously and those with severe symptoms should wear a medical information bracelet or chain and carry an <a href="https://www.healthdirect.gov.au/how-to-use-an-adrenaline-autoinjector-epipen-anapen">adrenaline auto-injector pen</a>. Concerningly, surveys suggest only <a href="https://pubmed.ncbi.nlm.nih.gov/30646188/">about one in four adults</a> with food allergy have an adrenaline pen. If you have an IgE-mediated food allergy, discuss your management plan with your doctor.

Sydneysiders witnessed horrific scenes on Saturday. How do you process and recover from such an event?

<a href="https://theconversation.com/profiles/kim-felmingham-9075">Kim Felmingham</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Like many, I watched the reports of the violent attack at Bondi Junction yesterday with shock, horror and disbelief. My heart goes out to the people involved, the courageous first responders and to those who have lost loved ones in this tragic event. I also feel for those who witnessed the horror and will be working out how to get through the initial shock and, over time, put it behind them. Distress and strong emotional reactions are <a href="https://kclpure.kcl.ac.uk/portal/en/publications/the-psychological-and-psychiatric-effects-of-terrorism-lessons-fr">common</a> after these types of mass violent events. But different people will have <a href="https://www.ptsd.va.gov/understand/types/mass_violence_help.asp">different emotional reactions</a> – and some may experience a range of shifting emotions. <h2>The first few days and weeks</h2> In the days and weeks after traumatic events like these, people <a href="https://www.ptsd.va.gov/understand/isitptsd/common_reactions.asp#:%7E:text=All%20kinds%20of%20trauma%20create,stop%20thinking%20about%20what%20happened.">often experience</a> a <a href="https://www.sciencedirect.com/science/article/abs/pii/S0306457320308670">range of emotions</a>: from fear and anxiety, anger, sadness and grief, disbelief and numbness, guilt and worry about safety. They may be jittery, more irritable or on edge, or it may affect their sleep. For many, their sense of risk may be heightened, particularly as such random violence occurred during such an ordinary event – shopping on a Saturday afternoon. This <a href="https://www.ptsd.va.gov/understand/types/mass_violence_help.asp">can lead to</a> a heightened awareness of danger and concern for safety. <h2>What’s likely to happen over time?</h2> For most people, as they begin to process and make sense of what happened, these feelings will gradually reduce in intensity and people will begin to recover. <a href="https://pubmed.ncbi.nlm.nih.gov/25311288/">Research shows</a> the majority of people recover from mass violent events within the initial few months. However, for people with more direct exposure to the trauma, these events and reactions may be more difficult to process. Some people <a href="https://pubmed.ncbi.nlm.nih.gov/26084284/">may go on</a> to develop mental health difficulties, most commonly anxiety, depression and post-traumatic stress disorder (PTSD). Understandably, those <a href="https://pubmed.ncbi.nlm.nih.gov/26084284/">more at risk</a> are people who were present during the trauma and experienced a direct threat, as well as those who witnessed the violence or aftermath, first responders (paramedics and police) and those who had loved ones injured or lost during the event. People who had more intense emotional responses during the trauma, or previous psychological difficulties or traumatic experiences, may also be <a href="https://pubmed.ncbi.nlm.nih.gov/26084284/">at greater risk</a>. <h2>What helps – and hinders – your recovery?</h2> To help process these traumatic events and promote recovery, social support is <a href="https://www.ptsd.va.gov/understand/types/mass_violence_help.asp">particularly important</a>. Spending time with trusted family and friends can help people process the events and their emotional reactions. Talking about your feelings with supportive people can help you understand and accept them. But even if you don’t want to talk about your feelings, spending time with loved ones is helpful. It is also fine to need some time to be alone, but try not to isolate yourself or withdraw. If you can’t talk about your feelings, try not to bottle them up or deal with them by using alcohol or drugs. Find <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7957853/">another way to express them</a> – whether through writing, art or music, or exercise. Give yourself permission and time to feel these emotions. Remind yourself you have just been through something extremely traumatic, take things day by day, and don’t expect too much of yourself. Try not to judge yourself for your actions or how you are coping. Keep some structure in your day, setting small goals, and increase your self-care: eat well, rest (even if you can’t sleep well), try yoga or relaxation. When you’re ready, try to get back to your normal routine. Seek out information from <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7957853/">trusted sources</a>, but try to <a href="https://journals.sagepub.com/doi/10.1177/0886260517742915">avoid</a> being saturated by images or stories about the trauma, particularly graphic footage or speculation common on social media. <h2>What if children have witnessed it, too?</h2> If your children have been impacted, reassure them that they are safe and loved. When they are ready, talk to them gently about the trauma, acknowledge it and answer their questions. Encourage them to express their feelings and spend more time together doing family activities. Importantly, try to limit their exposure to graphic footage and images of the events in the media, and on social media. <h2>When to seek mental health care</h2> Reach out for professional mental health support if you experience ongoing difficulty with your emotional reactions, or if you’re having distressing memories of the trauma, difficulty sleeping or nightmares, or you want to avoid things that remind you of the traumatic event. Not everyone requires professional mental health support, but if you are experiencing these types of post-traumatic stress reactions a few weeks after the trauma, it’s important to speak to your GP to seek out professional support from psychologists or counselling services.

How bad is junk food for you, really?

<div> Consuming more junk foods, such as soft drinks, packaged snacks, and sugary cereals, is associated with a higher risk of more than 30 different health problems – both physical and mental – according to researchers. A study, known as an umbrella review, combined the results of 45 previous meta-analyses published in the last three years, representing about 10 million participants. Thirty-two different poor health outcomes were found to be linked to the consumption of ultra-processed foods (UPFs), with varying levels of evidence supporting the findings. The researchers found the most convincing evidence around higher ultra-processed food intake, which was associated with a 50% increased risk of cardiovascular disease-related death, a 48-53% higher risk of anxiety and common mental disorders, and a 12% greater risk of type 2 diabetes. Evidence marked as ‘highly suggestive’ included a 21% increase in death from any cause, a 40-66% increased risk of a heart disease related death, obesity, type 2 diabetes, and sleep problems, as well as a 22% increased risk of depression. The review also found there may be links between ultra-processed food and asthma; gastrointestinal health; some cancers; and other risk factors such as high blood fats and low levels of ‘good’ cholesterol, but the researchers note this evidence is limited. Dr Daisy Coyle from the George Institute for Global Health in Sydney, who was not involved in the research, says the statistics are “staggering.” “Ultra-processed foods, laden with additives and sometimes lacking in essential nutrients, have become ubiquitous in the Australian diet,” she says. “In fact, they make up almost half of what we buy at the supermarket. While not all ultra-processed foods are linked to poor health outcomes, many are, particularly sugary drinks and processed meats.” <div> </div> While the findings are in line with other research that highlights the health risks associated with UPFs, some experts have pointed out that the study is observational, and therefore can’t prove the ultra-processed foods cause these health issues. It can only show an association. “While these associations are interesting and warrant further high-quality research, they do not and cannot provide evidence of causality,” The University of Sydney’s Dr Alan Barclay told the AusSMC. “By their very nature, observational studies are renowned for being confounded by numerous factors – both known and unknown.” Clare Collins, Laureate Professor at the University of Newcastle agreed, but added that it’s difficult to conduct dietary studies like this in a different way. “The studies are observational, which means cause and effect cannot be proven and that the research evidence gets downgraded, compared to intervention studies,” she says. “The problem is that it is not ethical to do an intervention study lasting for many years where you feed people lots of UPF every day and wait for them to get sick and die.” For now, researchers seem to agree that it can’t be a bad thing to minimise UPF intake. The review suggests a need for policies that pull consumers away from ultra-processed foods, such as advertising restrictions, warning labels, bans in schools and hospitals. It also calls for measures that make healthier foods more accessible and affordable. Dr Charlotte Gupta from Central Queensland University suggests that this is issue of accessibility is particularly relevant for shift workers such as doctors, nurses, firefighters, taxi drivers, miners, and hospitality workers. “There is a lack of availability of fresh foods or time to prepare any food, and so ultra-processed foods have to be relied on (e.g. from the vending machine in the hospital),” she said. “This highlights the need for not only individuals to try reducing ultra-processed foods in our diet, but also for public health actions to improve access to healthier foods.” Image credits: Shutterstock <a href="https://cosmosmagazine.com/health/how-bad-is-junk-food-for-you-really/">This article</a> was originally published on <a href="https://cosmosmagazine.com">Cosmos Magazine</a> and was written by <a href="https://cosmosmagazine.com/contributor/olivia-henry/">Olivia Henry</a>. </div>

Why is gluten-free bread so expensive? A food supply chain expert explains

<a href="https://theconversation.com/profiles/flavio-macau-998456">Flavio Macau</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> Before the cost of living hit Australian families hard, a group of consumers were already paying top dollar for their staples. Whether it be gluten free, dairy free or lactose free, people with special dietary requirements are used to spending more at the supermarket checkout. A 2016 study from the University of Wollongong found that Australians were <a href="https://onlinelibrary.wiley.com/doi/10.1111/1747-0080.12171">paying up to 17% more for a gluten-free diet</a>. Current examples are easy to find. A <a href="https://www.coles.com.au/product/coles-white-bread-650g-4901345">white sandwich loaf at Coles</a> costs A$2.40 (or A$0.37 per 100g), whereas <a href="https://www.coles.com.au/product/coles-i'm-free-from-white-loaf-500g-3216673">the cheapest gluten-free option</a> costs $5.70 (or $1.14 per 100g). That’s over three times as much. Prices are closer comparing Coles Full Cream Milk at A$1.50 per litre with Coles Lactose Free Lite Milk at A$1.60, the exception that confirms the rule. So why are allergen-free products more expensive? <h2>Is it the ingredients?</h2> If manufacturers pay more for ingredients, this is usually reflected in the price of the final product. Regular and gluten-free bread share many common ingredients, but there is a substantial change where wheat flour is replaced by gluten-free flour. This ingredient may cost manufacturers around two times as much given the uniqueness of gluten-free grains, seeds, and nuts. These special ingredients are not as abundant or easy to process as wheat, and are also a bit more difficult to buy in very large scale. For a simple reference, compare <a href="https://www.coles.com.au/product/coles-white-plain-flour-1kg-5881232">regular</a> and <a href="https://www.coles.com.au/product/coles-i'm-free-from-plain-flour-gluten-free-500g-2478197">gluten-free flour</a> at Coles. Gluten, <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/jgh.13703">a complex mixture of hundreds of related but distinct proteins</a>, has unique properties. It is a binding agent that improves texture in recipes. Gluten-free bread therefore needs extra help to, literally, hold it together. Additional items such as thickeners, tapioca and maize starches are added to gluten-free recipes to improve viscosity and keep baked items in shape. That means a longer ingredient list and a slightly more complex manufacturing process. So, from an ingredient perspective, gluten-free bread costs more than regular bread. This applies for other allergen-free products as well. But with so many common ingredients, it is reasonable to say that this is not the main explanation. <h2>Is it manufacturing and transporting?</h2> A substantial part of price differences between regular and allergen-free foods comes from <a href="https://www.investopedia.com/terms/e/economiesofscale.asp">economies of scale</a>. Regular products are manufactured in very large quantities, while allergen-free products involve much smaller volumes. Bulk buying from large suppliers gets you bigger discounts. The more machines in a factory, the cheaper it is to run them. Larger outputs coming from the same place mean smaller costs for each individual product. Given that you have fixed costs to pay anyway, size is king. You pay the same amount for a grain mill regardless of whether you grind one kilo or one tonne of grains a day. Sure, you spend more on electricity or gas, but those are <a href="https://corporatefinanceinstitute.com/resources/accounting/fixed-and-variable-costs/">variable costs</a>. Then, there is the need for rigorous quality control. The United Nations Food and Agriculture Organization has a detailed <a href="https://www.fao.org/fao-who-codexalimentarius/sh-proxy/en/?lnk=1&url=https%253A%252F%252Fworkspace.fao.org%252Fsites%252Fcodex%252FStandards%252FCXC%2B80-2020%252FCXC_080e.pdf">code of practice on food allergen management for food business operators</a>, covering harvesting, handling, storage, transportation, packaging, and more. The <a href="https://www.foodstandards.gov.au/food-standards-code">Australia New Zealand Food Standards Code</a> also sets specific standards. Deep cleaning machines, thoroughly checking that standards are met, and scrapping whole batches when they are not makes manufacturing allergen-free products more complex and expensive. The <a href="https://www.health.wa.gov.au/-/media/Files/Corporate/general-documents/food/PDF/DOHComplianceandEnforcementPolicyVersion3.pdf">implications for non-compliance</a> vary in severity, from a simple recall to a costly infringement notice, plus <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10574315/">reputational damage to consumer trust</a>. It is hard to exactly measure the impact of economies of scale and quality costs on the price of allergen-free products. Each manufacturer will have its own challenges and solutions. But it is reasonable to say a considerable chunk of the difference we see when comparing gluten-free bread with its regular counterpart comes from these factors. Transportation costs follow a similar rule. If it is easier and quicker to fill your trucks with regular products, while allergen-free products have a hard time making a full load, there are disadvantages in the latter. <h2>Is it the marketing strategy?</h2> The final consideration on allergen-free food prices has to do with competition and willingness to pay. A quick search on Coles’ website shows 276 results for “bread” once you remove the 42 items that are gluten-free. That means that there are many more brands and products competing for bread consumers than for gluten-free bread consumers. That’s over six to one! This means customers with dietary restrictions are at a disadvantage as they are beholden to the limited options on offer. As noted by the Australian Competition & Consumer Commission, “<a href="https://www.accc.gov.au/business/competition-and-exemptions/competition-and-anti-competitive-behaviour">competition leads to lower prices and more choice for consumers</a>”. Also, fewer allergen-free products make it to the “own brand” list. Australians are <a href="https://www.news.com.au/finance/money/costs/coles-woolworths-ownbrand-products-booming-on-back-of-costofliving-crisis/news-story/d0be8b8d6e98c0a6477959cd83da17ad">relying more on these when facing the cost-of-living crisis</a>. There is also the <a href="https://online.hbs.edu/blog/post/willingness-to-pay">willingness to pay</a>, where consumers pay more for products deemed as having higher value. <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/obr.13525">Research</a> shows that on average consumers are willing to pay 30% more for food products that they perceive to be healthier. Manufacturers and retailers more often than not will capitalise on that, increasing their profit margins for allergen-free products. <h2>4 tips for saving money if you have allergies</h2> People with dietary requirements looking to ease the cost of their weekly grocery shop should use the same strategies as every savvy consumer: <ul> <li>research prices</li> <li>buy larger quantities where possible</li> <li>keep a keen eye on price reduction and items on sale</li> <li>consider replacing products tagged “allergen-free” with alternatives from other categories, such as going for rice instead of gluten-free pasta in a dish.</li> </ul> In the long run, if more customers choose allergen-free products it could lead to more volume and competition, bringing prices down. <img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/223648/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/flavio-macau-998456">Flavio Macau</a>, Associate Dean - School of Business and Law, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
