Lisa Curry’s emotional plea 5 years after Jaimi's tragic death

Aussie swimming legend Lisa Curry has made a heartfelt appeal in memory of her late daughter, Jaimi Kenny, who tragically passed away in 2020 at the age of 33 following a prolonged and painful battle with alcoholism and an eating disorder. Appearing on Nine News, the 63-year-old former Olympian opened up about her devastating loss and called on Australians to participate in a groundbreaking new genetic study that aims to detect eating disorders from birth. “She just sort of took a breath and then her hands went cold – that was it,” Lisa recalled, her voice heavy with emotion. Jaimi’s struggle with anorexia, bulimia and binge eating left her mother with more questions than answers. “She’d say, ‘Where did it come from? Why am I like this?’” Lisa shared, still haunted by her daughter’s anguish. Now, in the midst of grief, Lisa is channelling her pain into purpose. She is urging Australians to volunteer for a pioneering genetic research project led by Queensland’s QIMR Berghofer Medical Research Institute. The study hopes to enlist 4,000 local participants and 100,000 globally, collecting saliva samples to identify potential genetic markers linked to eating disorders. Professor Nick Martin, who is leading the study, explained that genetic predisposition plays a significant role in the development of such illnesses – a discovery that could change lives and save them. Lisa’s renewed call for awareness and action follows her own harrowing health battles. In recent months, she revealed she’s been in “recovery” from the unrelenting grief of losing Jaimi. After more than three years, she finally returned to the gym – a milestone made even more significant by the physical pain of a hip replacement, the result of a fall while husky sledding in Canada last year. Lisa’s health history also includes myocarditis, a mitral valve prolapse inherited from her mother, and a fractured sternum. "Seventeen years ago, I had 22,000 irregular heartbeats a day,” she wrote. “That was the start of a different life.” Since the loss of Jaimi, Lisa has committed herself to raising awareness about the silent struggles so many face – especially when it comes to eating disorders. Her message is simple but urgent: more research, more understanding and more compassion are desperately needed. If you or someone you know is struggling with an eating disorder, support is available.

Seven things to eat or avoid to lower your blood pressure

<div class="theconversation-article-body"> High blood pressure is called the silent killer. That’s because it has <a href="http://www.heart.org/HEARTORG/Conditions/HighBloodPressure/SymptomsDiagnosisMonitoringofHighBloodPressure/What-are-the-Symptoms-of-High-Blood-Pressure_UCM_301871_Article.jsp#.V7OWWI9OI2w">no symptoms</a>. Having high blood pressure (hypertension) increases your risk of heart disease, stroke, heart failure and kidney disease. Six million Australian adults (34%) have high blood pressure – 140/90 millimetres of mercury (mmHg) or more – or take medications for it. Of those, <a href="https://heartfoundation.org.au/images/uploads/publications/PRO-167_Hypertension-guideline-2016_WEB.pdf">four million have high blood pressure that isn’t treated or under control</a>. No wonder heart disease and stroke directly cost the Australian economy <a href="http://www.aihw.gov.au/WorkArea/DownloadAsset.aspx?id=60129546379">A$7.7 billion a year</a>. There is some good news. High blood pressure can be treated or prevented. Eating oats, fruit and vegetables – and beetroot, in particular – helps. So does avoiding salt, liquorice, caffeine and alcohol. Optimal blood pressure is <a href="https://theconversation.com/blood-pressure-targets-what-does-the-new-guideline-say-and-how-low-should-you-go-62684">120 mmHg or less</a> over 80 mmHg or less. Lowering it by 1-2 mmHg can have a big impact on reducing your risk of heart disease and stroke, and the nation’s health care costs. <h2>What to eat to lower your blood pressure</h2> Rolled oats A <a href="http://www.ncbi.nlm.nih.gov/pubmed/25668347">review with five research trials included</a> tested the impact of oats on systolic blood pressure (the first blood pressure number, which is the pressure at which the heart pumps blood) and diastolic blood pressure (the second number, which is when the heart relaxes) in about 400 healthy adults. The researchers found that systolic blood pressure was 2.7 mmHg lower and diastolic blood pressure was 1.5 mmHg lower when participants ate around 60 grams of rolled oats (a packed half-cup raw oats) or 25 grams of oat bran per day. This quantity of oats or oat bran contains around four grams of a type of fibre called <a href="http://www.healthline.com/health/beta-glucan-heart-healthy">beta-glucan</a>. For each extra one gram of total daily fibre, there was an extra 0.11 mmHg reduction in diastolic blood pressure. <figure class="align-right "><figcaption></figcaption></figure> Recommended <a href="https://www.nrv.gov.au/nutrients/dietary-fibre">minimum daily adult fibre intakes</a> are 30 grams for men and 25 grams for women. While some of fibre’s effect is due to weight loss, soluble fibres produce bioactive products when they’re fermented in the large bowel. These work directly to lower blood pressure. To improve your blood pressure, eat rolled oats or oat bran for breakfast, add to meat patties, or mix with breadcrumbs in recipes that call for crumbing. Beetroot Beetroot is extremely rich in a compound called inorganic nitrate. During digestion, this gets converted into nitric oxide, which causes arteries to dilate. This directly lowers the pressure in them. A <a href="http://www.ncbi.nlm.nih.gov/pubmed/23596162">review of 16 trials</a> of mostly healthy young men found drinking beetroot juice was associated with a 4.4 mmHg reduction in systolic blood pressure. But it found no change in diastolic blood pressure. However a recent <a href="http://www.ncbi.nlm.nih.gov/pubmed/25421976">trial in 68 adults</a> who already had high blood pressure found beetroot juice reduced systolic and diastolic blood pressure. <figure class="align-right "><figcaption></figcaption></figure> The men were randomly assigned to drink 250ml (one cup) of beetroot juice daily for four weeks or a non-active placebo. Blood pressure in the men who drank the beetroot juice reduced over 24 hours, with systolic blood pressure 7.7 mmHg lower and diastolic blood pressure 5.2 mmHg lower. Try wrapping whole fresh beetroot in foil and baking in the oven until soft, or grate beetroot and stir-fry with red onion and curry paste and eat as a relish. Vitamin C Vitamin C, or <a href="https://en.wikipedia.org/wiki/Vitamin_C">ascorbic acid</a>, is found in fresh vegetables and fruit. An average serve contains 10-40mg of vitamin C. In a review of 29 short-term <a href="http://www.ncbi.nlm.nih.gov/pubmed/22492364">trials of vitamin C supplements</a>, people were given 500 mg of vitamin C per day for about eight weeks. Blood pressure significantly improved, with an average reduction in systolic blood pressure of 3.84 mmHg and 1.48 mmHg for diastolic blood pressure. <figure class="align-right "><figcaption></figcaption></figure> When only those with existing high blood pressure were considered, the drop in systolic blood pressure was 4.85 mmHg. However, those <a href="http://www.ncbi.nlm.nih.gov/pubmed/26463139">at risk of kidney stones</a> need to be cautious about taking vitamin C supplements. Excess vitamin C is excreted via the kidneys and can contribute to the formation of kidney stones. One advantage of getting more vitamin C from eating more vegetables and fruit is that you boost your potassium intake, which helps <a href="http://www.bloodpressureuk.org/microsites/salt/Home/Whypotassiumhelps">counter the effects of sodium</a> from salt. <h2>What to avoid to lower your blood pressure</h2> Salt Salt or <a href="https://en.wikipedia.org/wiki/Salt">sodium chloride</a> has been used to preserve foods and as a flavour enhancer for centuries. High salt intakes are <a href="http://www.bmj.com/content/312/7041/1249?ijkey=cd4b7840cc559055a2997d90100361217218f6e8&keytype2=tf_ipsecsha">associated with higher blood pressure</a>. <figure class="align-right "><figcaption></figcaption></figure> Adults <a href="https://www.nrv.gov.au/nutrients/sodium">need between 1.2 to 2.4g of salt each day</a> (one-quarter to a half teaspoon), which is equivalent to 460 to 920mg of sodium. But in Australia seven out of ten men and three in ten women eat way more than that – and much more than the upper recommended limit of 5.9 grams of salt (about one teaspoon) or <a href="http://www.abs.gov.au/ausstats/abs@.nsf/Lookup/by%20Subject/4364.0.55.008%7E2011-12%7EMain%20Features%7ESodium%7E403">2,300 mg of sodium per day</a>. If you add salt to food yourself this pushes your sodium intake even higher. A <a href="http://www.ncbi.nlm.nih.gov/pubmed/23558162">review of studies</a> involving 3,230 people showed that reducing salt intakes by 4.4 grams a day could reduce systolic blood pressure by about 4.2 mmHg and diastolic by 2.1 mmHg. In those who had high blood pressure there were even bigger reductions of 5.4 mmHg (systolic) and 2.8 mmHg (diastolic). Avoid foods high in sodium. Don’t add salt and try to choose lower-salt versions of processed foods. Alcohol Consuming one or more alcoholic drink a day is <a href="http://www.ncbi.nlm.nih.gov/pubmed/15752957">associated with systolic blood pressure</a> that is about 2.7 mmHg and diastolic blood pressure 1.4 mmHg higher than non-drinkers. Interestingly, when you first drink an alcoholic beverage, blood pressure goes down, only to rise later. <figure class="align-right "><figcaption></figcaption></figure> A rise in blood pressure after drinking alcohol is <a href="http://www.ncbi.nlm.nih.gov/pubmed/26123682">more likely to happen when you’re awake</a>, rather during sleep. The bad news is that larger amounts of alcohol increase your risk of high blood pressure, <a href="http://www.ncbi.nlm.nih.gov/pubmed/23126352">especially in men</a>, but also to a lesser extent <a href="http://www.ncbi.nlm.nih.gov/pubmed/19804464">in women</a>. Liquorice High blood pressure due to eating black liquorice is rare, but <a href="http://www.ncbi.nlm.nih.gov/pubmed/26380428">case reports have occurred</a>. Most liquorice candy sold currently contains very little true liquorice root and therefore, little <a href="https://en.wikipedia.org/wiki/Glycyrrhizin">glycyrrhizic acid</a> (GZA), the active ingredient. <figure class="align-right "><figcaption></figcaption></figure> Occasionally, liquorice candy does contain GZA in large amounts. <a href="http://www.ncbi.nlm.nih.gov/pubmed/10944880">GZA causes sodium retention and potassium loss</a>, which contributes to high blood pressure. So check liquorice food labels. Take care if it contains liquorice root. Caffeine Caffeine is most commonly consumed in coffee, tea, cola and energy drinks. High intakes of caffeine from coffee <a href="http://www.ncbi.nlm.nih.gov/pubmed/21880846">increase blood pressure</a> in the short term. <figure class="align-right "><figcaption></figcaption></figure> In a <a href="https://www.ncbi.nlm.nih.gov/pubmed/21880846">review of five trials</a>, people given one to two cups of strong coffee had an increase in their systolic blood pressure of 8.1 mmHg and 5.7 mmHg for diastolic blood pressure, up to about three hours after drinking it. But three studies that lasted two weeks found drinking coffee did not increase blood pressure compared with decaffeinated coffee or avoiding caffeine. So you need to monitor your individual response to caffeine.<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/63940/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> By <a href="https://theconversation.com/profiles/clare-collins-7316">Clare Collins</a>, Professor in Nutrition and Dietetics, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a>; <a href="https://theconversation.com/profiles/tracy-burrows-172931">Tracy Burrows</a>, Senior Lecturer Nutrition and Dietetics, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a>, and <a href="https://theconversation.com/profiles/tracy-schumacher-295602">Tracy Schumacher</a>, Research Associate, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Our ancestors didn’t eat 3 meals a day. So why do we?

<div class="theconversation-article-body"> Pop quiz: name the world’s most famous trio? If you’re a foodie, then your answer might have been breakfast, lunch and dinner. It’s an almost universally accepted trinity – particularly in the Western world. But how did it come about? <h2>The first meals</h2> <a href="https://theconversation.com/when-did-we-become-fully-human-what-fossils-and-dna-tell-us-about-the-evolution-of-modern-intelligence-143717#:%7E:text=Fossils%20and%20DNA%20suggest%20people,%3A%2050%2C000%2D65%2C000%20years%20ago">Early humans</a> were nomadic. Forming small communities, they would travel with the seasons, following local food sources. While we can only guess what daily mealtimes rhythms looked like, evidence dating back <a href="https://global.oup.com/academic/product/feast-9780199209019?cc=nz&lang=en&">30,000 years</a> from the South Moravia region, Czech Republic, shows people visited specific settlements time and again. They gathered around hearths, cooking and sharing food: the first signs of human “commensality”, the practice of eating together. One of the best-preserved hunter-gatherer sites we’ve found is <a href="https://global.oup.com/academic/product/feast-9780199209019?cc=nz&lang=en&">Ohalo II</a> – located on the shores of the modern-day Sea of Galilee (also called Lake Tiberias or Lake Kinneret) in Israel, and dating back some 23,000 years. In addition to several small dwellings with hearths, it provides evidence of diverse food sources, including more than 140 types of seeds and nuts, and various birds, fish and mammals. The development of <a href="https://education.nationalgeographic.org/resource/development-agriculture/">agricultural knowledge</a> some 12,000 years ago gave rise to permanent settlements. The earliest were in the Levant region (across modern-day Iraq, southwestern Iran and eastern Turkey), in an area called the “Fertile Crescent”. Permanent agriculture led to the production of a <a href="https://www.nationalgeographic.com/foodfeatures/evolution-of-diet/">surplus of food</a>. The ability to stay in one place with food on-hand meant the time it took to cook no longer mattered as much. It quickly became common to eat one <a href="https://www.bloomsbury.com/us/history-of-the-world-in-6-glasses-9780802718594/">light meal</a> early in the day, followed by a larger <a href="https://global.oup.com/academic/product/feast-9780199209019?cc=nz&lang=en&">hearth-prepared meal</a> later on. The specific timings would have varied between groups. <h2>Eating together as a rule</h2> The communal nature of foraging and hunting, and later farming, meant humans almost always ate their meals in the <a href="https://doi.org/10.1525/gfc.2009.9.3.42">company of others</a>. In the ancient city-state of Sparta, in the <a href="https://doi.org/10.2307/293895">4th century BCE</a>, these practices were codified as common main meals called <a href="https://doi.org/10.1525/gfc.2017.17.2.51">syssitia</a> (meaning “eating together”). These meals were consumed at the end of the day in communal dining halls. Food was served by young boys to tables of 15 or so men who lived together and fought in the same <a href="https://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0063%3Aalphabetic+letter%3DS%3Aentry+group%3D5%3Aentry%3Dsyssitia-cn">military division</a>. The men gradually shared generational knowledge with the young boys, who themselves would join the tables by age 20. In the 5th century BCE, Greek historian Herodotus <a href="https://www.penguin.co.nz/books/the-histories-9780140455397">wrote about</a> how syssitia evolved from a Spartan military practice to having deep political meaning in society. Similarly, <a href="https://www.penguin.co.nz/books/the-republic-9780140455113">Plato</a> <a href="https://www.penguin.co.nz/books/the-laws-9780140449846">wrote</a> common meals were an integral component of civil society, and that missing a meal without good reason was a civic offence. By dining in <a href="https://doi.org/10.2307/293895">full view</a> of the rest of society, citizens were compelled to maintain self-discipline. Mealtime was also an opportunity for social linkage, and <a href="https://doi.org/10.1525/gfc.2017.17.2.51">important discussions</a> ranging from business deals to politics. The eating habits of Spartan women are missing in the texts, although it is implied they <a href="https://doi.org/10.1525/gfc.2017.17.2.51">ate at home</a>. <h2>Bunches of lunches</h2> Counter to the tough Spartan way of life, the Romans enjoyed their main meal, <a href="https://www.press.jhu.edu/books/title/1550/everyday-life-ancient-rome?srsltid=AfmBOooVPsJL24HR9woTdVNQwEG1uCU7q0k7r2beD-KD13m0KX-l1dSY">cena</a>, earlier in the day, followed by a lighter meal just before bed. The northern European tribes tended towards two larger meals per day, as more <a href="https://doi.org/10.1002/ajpa.23071">sustenance</a> is required in colder climes. To the Vikings, these meals were known as <a href="https://www.historyonthenet.com/what-did-vikings-eat">dagmal and nattmal</a>, or day meal and night meal. Nattmal was the cooked evening meal, while dagmal usually consisted of leftover nattmal with the addition of bread and beer or mead. In Australia, evidence suggests Aboriginal peoples tended toward a <a href="https://www.tandfonline.com/doi/full/10.1080/03122417.2022.2089395">daily single meal</a>, which aligns with the predominant method of cookery: slow-cooking with hot coals or rocks in an <a href="https://doi.org/10.1080/03122417.2022.2089395">earth oven</a>. This underground oven, used by Aboriginal and also Torres Strait Islander communities, was referred to as a <a href="https://www.facebook.com/watch/?v=745326709638881&t=0">kup murri</a> or <a href="https://www.sbs.com.au/food/the-cook-up-with-adam-liaw/recipe/slow-cooker-kap-mauri/lfza7eqs4">kap mauri</a> by some groups. This is similar to other Indigenous preparations throughout the Pacific, such as the New Zealand Māori <a href="https://doi.org/10.1080/15528014.2024.2381305">hāngī</a>, Hawaiian <a href="https://www.jstor.org/stable/20707103?seq=1">imu</a>, Fijian <a href="https://www.proquest.com/docview/1021389307?accountid=8440&parentSessionId=605Pt1iTclBEC77VSlZvrnxxY%2Bdc7e%2Bx9pT4MgRLPqQ%3D&sourcetype=Dissertations%20&%20Theses">lovo</a>, and even the Mayan <a href="https://doi.org/10.1007/s12231-012-9207-2">píib</a>. The once-daily meal would have been supplemented with snacks throughout the day. <h2>Three’s the magic number</h2> The timing of meals was heavily influenced by class structure, local climate and people’s <a href="https://www.wiley.com/en-us/Cuisine+and+Culture%3A+A+History+of+Food+and+People%2C+3rd+Edition-p-9780470403716">daily activities</a>. Practicality also played a part. Without reliable lighting, meals had to be prepared and eaten before dark. In settled parts of Northern Europe, this could be as early as 3pm. So how did we go from one or two main meals, to three? The answer may lie with the British Royal Navy. Since its inception in the 16th century, the navy served <a href="https://www.historyhit.com/what-did-sailors-in-the-georgian-royal-navy-eat/">three regular meals</a> to align with the shipboard routine. This included a simple breakfast of ship’s biscuits, lunch as the main meal, and dinner as more of a light supper. Some sources suggest the term “<a href="https://www.grammar-monster.com/sayings_proverbs/square_meal.htm">square meal</a>” may have come from the square wooden trays meals were served in. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=455&fit=crop&dpr=1 600w, https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=455&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=455&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=572&fit=crop&dpr=1 754w, https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=572&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=572&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>Initially, sailors recieved a daily gallon of beer with meals.

The cadence of breakfast, lunch and dinner matched the routine of the longer, standardised workdays. Workers ate breakfast and dinner at home, before and after work, while lunch was eaten with coworkers at a set time. With minimal breaks, and no time for snacking, three substantial meals became necessary. <h2>The fall of the holy trinity</h2> Today, many factors impact the <a href="https://doi.org/10.1016/j.cmet.2015.09.005">time and frequency</a> of our meals, from long work commutes to juggling hobbies and social obligations. The COVID pandemic also impacted how and what we eat, leading us to eat larger amounts of <a href="https://doi.org/10.1016/j.jhealeco.2022.102641">higher calorie foods</a>. The rapid growth of <a href="https://doi.org/10.1017/S1368980020000701">delivery services</a> also means a meal is no more than a few minutes away from most people. All of this has resulted in mealtimes becoming less rigid, with social meals such as <a href="https://rowman.com/ISBN/9781442229433/Brunch-A-History">brunch</a>, <a href="https://www.harpercollins.co.nz/9780261102354/the-fellowship-of-the-ring/">elevenses</a> and <a href="https://rowman.com/ISBN/9781442271029/Afternoon-Tea-A-History">afternoon teas</a> expanding how we <a href="https://doi.org/10.3390/ijerph18126235">connect over food</a>.

This is an issue because <a href="https://www.aihw.gov.au/reports/risk-factors/risk-factors-to-health/contents/overweight-and-obesity">excess fat</a> <a href="https://pubmed.ncbi.nlm.nih.gov/27423262/">increases the risk</a> of type 2 diabetes, heart disease and certain cancers. <a href="https://pubmed.ncbi.nlm.nih.gov/33393504/">Modifying your diet</a> is important for managing obesity and preventing weight gain. This might include reducing your calorie intake, changing your <a href="https://pubmed.ncbi.nlm.nih.gov/39143663/">eating patterns</a> and prioritising healthy food. But is one formula for weight loss more likely to result in success than another? Our <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11530941/">new research</a> compared three weight-loss methods, to see if one delivered more weight loss than the others: <ul> <li>altering calorie distribution – eating more calories earlier rather than later in the day</li> <li>eating fewer meals</li> <li>intermittent fasting.</li> </ul> We analysed data from 29 clinical trials involving almost 2,500 people. We found that over 12 weeks or more, the three methods resulted in similar weight loss: 1.4–1.8kg. So if you do want to lose weight, choose a method that works best for you and your lifestyle. <h2>Eating earlier in the day</h2> When our metabolism <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/metabolic-syndrome">isn’t functioning properly</a>, our body can’t respond to the hormone insulin properly. This can lead to weight gain, fatigue and can increase the risk of a number of chronic diseases such as diabetes. Eating later in the day – with a <a href="https://pubmed.ncbi.nlm.nih.gov/23512957/">heavy dinner</a> and late-night snacking – seems to lead to <a href="https://pubmed.ncbi.nlm.nih.gov/33172509/">worse metabolic function</a>. This means the body becomes less efficient at converting food into energy, managing blood sugar and regulating fat storage. In contrast, consuming calories <a href="https://pubmed.ncbi.nlm.nih.gov/31151228/">earlier</a> in the day appears to <a href="https://pubmed.ncbi.nlm.nih.gov/29754952/">improve</a> metabolic function. However, this might not be the case for everyone. Some people naturally have an evening “chronotype”, meaning they wake up and stay up later. People with this chronotype appear to have <a href="https://pubmed.ncbi.nlm.nih.gov/36803075/">less success losing weight</a>, no matter the method. This is due to a combination of factors including genes, an increased likelihood to have a poorer diet overall and higher levels of hunger hormones. <h2>Eating fewer meals</h2> <a href="https://pubmed.ncbi.nlm.nih.gov/30700403/">Skipping breakfast</a> is common, but does it hinder weight loss? Or is a <a href="https://pubmed.ncbi.nlm.nih.gov/28967343/">larger breakfast and smaller dinner</a> ideal? While <a href="https://pubmed.ncbi.nlm.nih.gov/28137935/">frequent meals</a> may reduce disease risk, recent studies suggest that compared to eating one to two meals a day, eating six times a day might increase <a href="https://pubmed.ncbi.nlm.nih.gov/32437566/">weight loss success</a>. However, this doesn’t reflect the broader research, which tends to show consuming <a href="https://pubmed.ncbi.nlm.nih.gov/33485709/">fewer meals</a> can lead to greater weight loss. <a href="https://pubmed.ncbi.nlm.nih.gov/39485353/">Our research</a> suggests three meals a day is better than six. The easiest way to do this is by cutting out snacks and keeping breakfast, lunch and dinner. Most studies compare three versus six meals, with limited evidence on whether <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7490164/">two meals is better than three</a>. However, <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11530941/">front-loading your calories</a> (consuming most of your calories between breakfast and lunch) appears to be better for weight loss and may also help <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9605877/">reduce hunger</a> across the day. But more studies with a longer duration are needed. <h2>Fasting, or time-restricted eating</h2> Many of us eat over a period of more than <a href="https://pubmed.ncbi.nlm.nih.gov/26411343/">14 hours a day</a>. Eating late at night <a href="https://pubmed.ncbi.nlm.nih.gov/26411343/">can throw off</a> your body’s natural rhythm and alter how your organs function. Over time, this can increase your risk of type 2 diabetes and other chronic diseases, particularly among <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8617838/">shift workers</a>. <a href="https://pubmed.ncbi.nlm.nih.gov/35194176/">Time-restricted eating</a>, a form of intermittent fasting, means eating all your calories within a <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7262456/">six- to ten-hour window</a> during the day when you’re most active. It’s not about changing what or how much you eat, but <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7262456/">when you eat it</a>. <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7262456/">Animal studies</a> suggest time-restricted eating can lead to weight loss and improved metabolism. But the evidence in humans is still limited, especially about the long-term benefits. It’s also unclear if the benefits of time-restricted eating are due to the timing itself or because people are eating less overall. When we looked at studies where participants ate freely (with no intentional calorie limits) but followed an eight-hour daily eating window, they naturally consumed about 200 fewer calories per day. <h2>What will work for you?</h2> In the past, clinicians have thought about weight loss and avoiding weight gain as a simile equation of calories in and out. But factors such as how we distribute our calories across the day, how often we eat and whether we eat late at night may also impact our metabolism, weight and health. There are no easy ways to lose weight. So choose a method, or combination of methods, that suits you best. You might consider <ul> <li>aiming to eat in an eight-hour window</li> <li>consuming your calories earlier, by focusing on breakfast and lunch</li> <li>opting for three meals a day, instead of six.</li> </ul> The <a href="https://link.springer.com/article/10.1007/s13679-024-00555-2">average adult gains 0.4 to 0.7 kg per year</a>. Improving the quality of your diet is important to prevent this weight gain and the strategies above might also help. Finally, there’s still a lot we don’t know about these eating patterns. Many existing studies are short-term, with small sample sizes and varied methods, making it hard to make direct comparisons. More research is underway, including well-controlled trials with larger samples, diverse populations and consistent methods. So hopefully future research will help us better understand how altering our eating patterns can result in better health.<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/242028/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/hayley-oneill-1458016">Hayley O'Neill</a>, Assistant Professor, Faculty of Health Sciences and Medicine, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/loai-albarqouni-452476">Loai Albarqouni</a>, Assistant Professor | NHMRC Emerging Leadership Fellow, <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.

For type 2 diabetes, focusing on when you eat – not what – can help control blood sugar

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/evelyn-parr-441878">Evelyn Parr</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> and <a href="https://theconversation.com/profiles/brooke-devlin-2237174">Brooke Devlin</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Type 2 diabetes affects <a href="https://www.aihw.gov.au/reports/diabetes/diabetes/contents/how-common-is-diabetes/type-2-diabetes">1.2 million Australians</a> and accounts for <a href="https://www.diabetesaustralia.com.au/about-diabetes/type-2-diabetes/">85-90%</a> of all diabetes cases. This chronic condition is characterised by high blood glucose (sugar) levels, which carry serious <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(17)30058-2/abstract">health</a> risks. <a href="https://www.nature.com/articles/nrendo.2017.151">Complications</a> include heart disease, kidney failure and vision problems. Diet is an important way people living with type 2 diabetes manage blood glucose, alongside exercise and medication. But while we know individualised, professional dietary advice improves blood glucose, it can be <a href="https://linkinghub.elsevier.com/retrieve/pii/S0168822717317588">complex</a> and is not always <a href="https://www.publish.csiro.au/py/PY13021">accessible</a>. <a href="https://www.sciencedirect.com/science/article/pii/S0168822724008039">Our new study</a> looked at the impact of time-restricted eating – focusing on when you eat, rather than what or how much – on blood glucose levels. We found it had similar results to individualised advice from an accredited practising dietitian. But there were added benefits, because it was simple, achievable, easy to stick to – and motivated people to make other positive changes. <h2>What is time-restricted eating?</h2> Time-restricted eating, also known as <a href="https://www.annualreviews.org/content/journals/10.1146/annurev-nutr-082018-124320">the 16:8 diet</a>, became popular for weight loss around 2015. Studies have since shown it is also an <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2811116">effective way</a> for people with type 2 diabetes to manage blood glucose. Time-restricted eating involves limiting when you eat each day, rather than focusing on what you eat. You restrict eating to a window during daylight hours, for example between 11am and 7pm, and then fast for the remaining hours. This can sometimes naturally lead to also eating less. Giving your body a break from constantly digesting food in this way helps align eating with natural <a href="https://doi.org/10.1111/jne.12886">circadian rhythms</a>. This <a href="https://doi.org/10.1111/jnc.15246">can help</a> regulate metabolism and improve overall health. For people with type 2 diabetes, there may be specific benefits. They often have their <a href="https://doi.org/10.2337/dc12-2127">highest blood glucose</a> reading in the morning. Delaying breakfast to mid-morning means there is time for physical activity to occur to help reduce glucose levels and prepare the body for the first meal. <h2>How we got here</h2> We ran an <a href="https://www.mdpi.com/2072-6643/12/11/3228">initial study</a> in 2018 to see whether following time-restricted eating was achievable for people with type 2 diabetes. We found participants could easily stick to this eating pattern over four weeks, for an average of five days a week. Importantly, they also had improvements in blood glucose, spending less time with high levels. <a href="https://www.mdpi.com/2072-6643/12/2/505">Our previous research</a> suggests the reduced time between meals may play a role in how the hormone insulin is able to reduce glucose concentrations. <a href="https://doi.org/10.1001/jamanetworkopen.2023.39337">Other studies</a> have confirmed these findings, which have <a href="https://doi.org/10.1186/s12986-021-00613-9">also shown</a> notable improvements in HbA1c. This is a <a href="https://www.ncbi.nlm.nih.gov/books/NBK304271/">marker</a> in the blood that represents concentrations of blood glucose over an average of three months. It is the <a href="https://journals.sagepub.com/doi/10.4137/BMI.S38440">primary clinical tool</a> used for diabetes. However, these studies provided intensive support to participants through weekly or fortnightly meetings with researchers. While we know this level of support <a href="https://www.nature.com/articles/0802295">increases</a> how likely people are to stick to the plan and improves outcomes, it is not readily available to everyday Australians living with type 2 diabetes. <h2>What we did</h2> In our <a href="https://www.sciencedirect.com/science/article/pii/S0168822724008039">new study</a>, we compared time-restricted eating directly with advice from an <a href="https://dietitiansaustralia.org.au/working-dietetics/standards-and-scope/role-accredited-practising-dietitian">accredited practising dietitian</a>, to test whether results were similar across six months. We recruited 52 people with type 2 diabetes who were currently managing their diabetes with up to two oral medications. There were 22 women and 30 men, aged between 35 and 65. Participants were randomly divided into two groups: diet and time-restricted eating. In both groups, participants received four consultations across the first four months. During the next two months they managed diet alone, without consultation, and we continued to measure the impact on blood glucose. In the diet group, consultations focused on changing their diet to control blood glucose, including improving diet quality (for example, eating more vegetables and limiting alcohol). In the time-restricted eating group, advice focused on how to limit eating to a nine-hour window between 10am and 7pm. Over six months, we measured each participant’s blood glucose levels every two months using the HbA1c test. Each fortnight, we also asked participants about their experience of making dietary changes (to what or when they ate). <h2>What we found</h2> We found time-restricted eating was as effective as the diet intervention. Both groups had reduced blood glucose levels, with the greatest improvements occurring after the first two months. Although it wasn’t an objective of the study, some participants in each group also lost weight (5-10kg). When surveyed, participants in the time-restricted eating group said they had adjusted well and were able to follow the restricted eating window. Many told us they had family support and enjoyed earlier mealtimes together. Some also found they slept better. After two months, people in the time-restricted group were looking for more dietary advice to further improve their health. Those in the diet group were less likely to stick to their plan. Despite similar health outcomes, time-restricted eating seems to be a simpler initial approach than making complex dietary changes. <h2>Is time-restricted eating achievable?</h2> The main barriers to following time-restricted eating are social occasions, caring for others and work schedules. These factors may prevent people eating within the window. However, there are many benefits. The message is simple, focusing on when to eat as the main diet change. This may make time-restricted eating more translatable to people from a wider variety of socio-cultural backgrounds, as the types of foods they eat don’t need to change, just the timing. Many people don’t have access to more individualised support from a dietitian, and receive nutrition advice from their GP. This makes time-restricted eating an alternative – and equally effective – strategy for people with type 2 diabetes. People should still try to stick to <a href="https://www.eatforhealth.gov.au/guidelines/guidelines">dietary guidelines</a> and prioritise vegetables, fruit, wholegrains, lean meat and healthy fats. But our study showed time-restricted eating may also serve as stepping stone for people with type 2 diabetes to take control of their health, as people became more interested in making diet and other positive changes. Time-restricted eating might not be appropriate for everyone, especially people on medications which don’t recommend fasting. Before trying this dietary change, it’s best speak to the healthcare professional who helps you manage diabetes.<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/241472/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/evelyn-parr-441878">Evelyn Parr</a>, Research Fellow in Exercise Metabolism and Nutrition, Mary MacKillop Institute for Health Research, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> and <a href="https://theconversation.com/profiles/brooke-devlin-2237174">Brooke Devlin</a>, Lecturer in Nutrition and Dietetics, School of Human Movement and Nutrition Sciences, <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.

5 items you’re cleaning too much

Cleaning the house is no easy feat. To make life a little easier for you, here are five items you are probably cleaning more than you need to. 1. Clothes worn once For particular items of clothing such as gym gear, shirts and tights it is fine to wash clothes after every wear. However, most other items can be worn up to three times advises Carolyn Forte, the director of the Cleaning Lab at the Good Housekeeping Institute. "Over-washing and over-drying fabrics can cause fading and wear,” she said. Studies have also shown that it is ideal to wash bath towels after three uses. 2. Dinner plates Instead of spending time rinsing your plates before putting them in the dishwasher, just make sure all the food is scrapped off. "Pre-washing dishes is a waste of time and energy,” said Carolyn. "If you aren't running it right away, let the dishwasher rinse them with a 'rinse only' cycle." 3. Light Fixtures It can be tempting to dust your light fixtures every week but Carolyn advises saving your strength from a different household task. She advises that you can get away with cleaning light fixtures once a month. 4. Jackets In the cooler months jackets are worn every day. However, this necessity only needs to be washed every three months. Jackets don’t usually come into contact with skin cells or natural oils, which allows them to go longer between washes than other clothes. 5. Curtains Curtains need to be washed if you get any marks on them but if they are in pristine condition, according to Carolyn they only need to be cleaned once a year. Image credits: Shutterstock

Grave cleaning videos are going viral on TikTok. Are they honouring the dead, or exploiting them?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/edith-jennifer-hill-1018412">Edith Jennifer Hill</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> and <a href="https://theconversation.com/profiles/marina-deller-947925">Marina Deller</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> Cleaning the graves of strangers is the latest content trend taking over TikTok. But as millions tune in to watch the videos, it’s becoming clear not all of them are created equal. Two grave-cleaning creators in particular seem to reside at opposite ends of the trend. One of the first accounts to gain popularity for grave cleaning was <a href="https://www.tiktok.com/@ladytaphos">@ladytaphos</a>. This account is run by Alicia Williams, a Virginia resident who treats the graves with great dignity. Williams will often share the story of the person residing within, and acts with grace and kindness as she restores beauty to the <a href="https://www.tiktok.com/@ladytaphos/video/7197894295641148714">graves</a>. On the other end of the spectrum is Kaeli Mae McEwen, or <a href="https://www.tiktok.com/@_the_clean_girl">@the_clean_girl</a>, who leans into more clickbait-y tactics. McEwen is known for throwing a pink spiky ball through a graveyard and cleaning the grave it lands on. She also uses her videos to promote her own pink foamy cleaner (which at one point could be purchased via a link in her bio). <h2>Cleaning and death</h2> While Williams’ and McEwen’s videos may seem novel to some, death and cleaning have a long and varied relationship that spans time and cultures. Washing a loved one’s body before burial or cremation isn’t just practical – it’s a significant <a href="https://www.theage.com.au/national/victoria/washing-and-dressing-our-dead-the-movement-challenging-how-we-grieve-20230510-p5d794.html">ritual</a> that provides meaning during a period of grief. In certain cultures and religions it’s also a process of purification, or preparation for the afterlife. Much has been written about cleaning and clearing out the homes of deceased people. Family members often won’t agree on how to approach such a task. In his <a href="https://theconversation.com/friday-essay-grief-and-things-of-stone-wood-and-wool-136721">essay on death and objects</a>, author Tony Birch writes about his mother clearing out his grandmother’s house. “My mother decided that our first task after her death was to empty out her Housing Commission flat and scrub it clean,” Birch writes. He first laments the move, but later recognises the value of cleaning together before sorting – and treasuring – the items his grandmother left behind. Margaretta Magnuson’s 2017 book, <a href="https://www.google.com.au/books/edition/The_Gentle_Art_of_Swedish_Death_Cleaning/uW00DwAAQBAJ?hl=en&gbpv=1&pg=PT7&printsec=frontcover">The Gentle Art of Swedish Death Cleaning</a>, is a humorous and thoughtful introduction to the Swedish movement of döstädning. The book (and subsequent <a href="https://www.sbs.com.au/ondemand/tv-series/the-gentle-art-of-swedish-death-cleaning">reality TV series</a>) has sparked various conversations on death and cleaning, and especially on cleaning before you yourself pass away so you don’t leave a mess for your loved ones. Grave cleaning can be seen as another continuation of caring for the deceased. People who decide to clean the graves of strangers may do so out of <a href="https://www.theguardian.com/society/2022/sep/04/how-gravetok-videos-of-cleaning-headstones-went-viral">respect</a>, or in an attempt to <a href="https://www.buzzfeed.com/alexalisitza/tiktok-woman-cleans-old-gravestones">give them “their name back”</a> (as names on graves become visible following the removal of debris). <h2>Two very different approaches</h2> Williams and McEwen are received quite differently by viewers. Anecdotally, viewers respond more positively to the calmer and more respectful cleaning videos by Williams, who takes time to explain the process while ensuring the correct products are used. Meanwhile, many find McEwen’s videos problematic and criticise her for not adhering to proper graveyard decorum. McEwen makes a spectacle of sites of mourning, such as by pretending to vacuum graves, replacing flowers placed by others and making jokes. Viewers also speculate the products she uses may cause damage to the graves. Perceived intent plays a role in how each creator’s content is received. While Williams focuses on respectfully restoring graves to their former glory, McEwen positions herself as the focus and merely uses the graves for content. <h2>A complex emotional object</h2> Similar to other funerary objects such as coffins and urns, graves are associated with both the person who died and the fact of their death. As such, they are emotionally complex objects that bring both strength and sadness to those left behind. But graves are unique also in that they are private objects of grief exposed in a public context. Anyone visiting the graveyard can view and interact with them. Does that make them “fair game” for content creators? Graves don’t just represent deceased loved ones. They can also act as stand-ins in their absence, becoming stone bodies of sorts. As sociologist Margaret Gibson describes in her book <a href="https://www.mup.com.au/books/objects-of-the-dead-paperback-softback">Objects of the Dead: Mourning and Memory in Everyday Life</a>, “death reconstructs our experience of objects”. “There is the strangeness of realising that things have outlived persons, and, in this regard, the materiality of things is shown to be more permanent than the materiality of the body,” she says. Caring for and cleaning graves can therefore be interpreted as caring for the deceased, by extending their existence through the materiality of their resting place. Psychological researcher <a href="https://www.tandfonline.com/doi/abs/10.1080/1600910X.2018.1521339">Svend Brinkmann asserts</a> artefacts such as graves are “culturally sanctioned”, gaining “significance from a collective system of meaning”. In other words, we as a community create and uphold reverence for such items. This is partly why the desecration of graves is viewed as abhorrent. It is societally understood to be a desecration of the person themselves. It’s also why content creators must tread lightly. <h2>A reason for haunting?</h2> There are ways to interact with gravestones (and even create content) which acknowledge their complexity and connection to their owners. TikTok creator Rosie Grant (<a href="https://www.tiktok.com/@ghostlyarchive?lang=en">@ghostlyarchive</a>) bakes recipes found on headstones and records the process. She has even met with the families of the deceased <a href="https://www.independent.co.uk/life-style/food-and-drink/defining-dishes-ghostly-archive-tiktok-b2414122.html">to make the recipes together</a> and learn more about the people behind the engraving-worthy food. However, randomly cleaning the graves of strangers is fraught territory – and rife with potential privacy issues. It isn’t clear whether McEwen seeks permission from loved ones before cleaning graves, but contextually this seems unlikely. <a href="https://www.youtube.com/watch?v=nKkOS2GjCxk">Recent discussions</a> have also uncovered questionable editing in her videos. Some graves in her before-and-after videos have been edited to appear cleaner and to have their structure altered. McEwen’s pink foaming cleaner also appears to be a blue cleaner edited to appear pink, raising even more questions about intent and responsibility. While McEwen claims to be “honouring” lives by cleaning “final resting places”, the consensus from viewers is her actions are dishonourable. As one host <a href="https://www.youtube.com/watch?v=nKkOS2GjCxk">commented on a in podcast</a> discussing McEwen cleaning a baby’s grave while speaking in a kiddish voice: “F**k you, you’re going to get haunted.”<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/240553/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/edith-jennifer-hill-1018412">Edith Jennifer Hill</a>, Associate Lecturer, Learning & Teaching Innovation, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> and <a href="https://theconversation.com/profiles/marina-deller-947925">Marina Deller</a>, Casual Academic, Creative Writing and English Literature, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Caring

Yes, you do need to clean your tongue. Here’s how and why

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/dileep-sharma-1562149">Dileep Sharma</a>, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a> Has your doctor asked you to stick out your tongue and say “aaah”? While the GP assesses your throat, they’re also checking out your tongue, which can reveal a lot about your health. The doctor will look for any changes in the tongue’s surface or how it moves. This can indicate issues in the mouth itself, as well as the state of your overall health and immunity. But there’s no need to wait for a trip to the doctor. Cleaning your tongue <a href="https://pubmed.ncbi.nlm.nih.gov/21797979/">twice a day</a> can help you check how your tongue looks and feels – and improve your breath. <h2>What does a healthy tongue look like?</h2> Our tongue plays a crucial role in eating, talking and other vital functions. It is not a single muscle but rather a muscular organ, made up of eight muscle pairs that help it move. The surface of the tongue is covered by tiny bumps that can be seen and felt, called papillae, giving it a rough surface. These are sometimes mistaken for taste buds – they’re not. Of your 200,000-300,000 papillae, only a small fraction contain taste buds. Adults have up to 10,000 taste buds and they are invisible to the naked eye, concentrated mainly on the tip, sides and back of the tongue. <figure><iframe src="https://www.youtube.com/embed/uYvpUl7li9Y?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> A healthy tongue is pink although the shade may vary from person to person, ranging from dark to light <a href="https://my.clevelandclinic.org/health/symptoms/24600-tongue-color">pink</a>. A small amount of white coating can be normal. But significant changes or discolouration may indicate a disease or <a href="https://www.healthline.com/health/tongue-problems-2">other issues</a>. <h2>How should I clean my tongue?</h2> Cleaning your tongue only takes around 10-15 seconds, but it’s is a good way to check in with your health and can easily be incorporated into your teeth brushing routine. You can clean your tongue by gently scrubbing it with a regular toothbrush. This dislodges any food debris and helps prevent microbes building up on its rough textured surface. Or you can use a special <a href="https://pubmed.ncbi.nlm.nih.gov/26865433/">tongue scraper</a>. These curved instruments are made of metal or plastic, and can be used alone or accompanied by scrubbing with your toothbrush. Your co-workers will thank you as well – cleaning your tongue can help combat <a href="https://pubmed.ncbi.nlm.nih.gov/24165218/">stinky breath</a>. Tongue scrapers are particularly <a href="https://pubmed.ncbi.nlm.nih.gov/15341360/">effective</a> at removing the bacteria that commonly causes bad breath, hidden in the tongue’s surface. <h2>What’s that stuff on my tongue?</h2> So, you’re checking your tongue during your twice-daily clean, and you notice something different. Noting these signs is the first step. If you observe any changes and they worry you, you should talk to your GP. Here’s what your tongue might be telling you. White coating Developing a white coating on the tongue’s surface is one of the <a href="https://pubmed.ncbi.nlm.nih.gov/31309703/">most common changes</a> in healthy people. This can happen if you stop brushing or scraping the tongue, even for a few days. In this case, food debris and microbes have accumulated and caused plaque. Gentle scrubbing or scraping will remove this coating. Removing microbes reduces the risk of chronic infections, which can be transferred to other organs and cause <a href="https://www.nature.com/articles/s41368-022-00163-7">serious illnesses</a>. Yellow coating This may indicate oral thrush, a <a href="https://www.nidirect.gov.uk/conditions/oral-thrush-adults">fungal infection</a> that leaves a raw surface when scrubbed. Oral thrush is <a href="https://www.aafp.org/pubs/afp/issues/2008/1001/p845.html">common</a> in elderly people who take multiple medications or have diabetes. It can also affect children and young adults after an illness, due to the temporary <a href="https://pubmed.ncbi.nlm.nih.gov/7636666/">suppression of the immune system</a> or <a href="https://www.stanfordchildrens.org/en/topic/default?id=candidiasis-in-children-90-P01888">antibiotic</a> use. If you have oral thrush, a doctor will usually prescribe a course of anti-fungal medication for at least a month. Black coating Smoking or consuming a lot of strong-coloured food and drink – such as tea and coffee, or dishes with tumeric – can cause a furry appearance. This is known as a <a href="https://my.clevelandclinic.org/health/diseases/17918-black-hairy-tongue">black hairy tongue</a>. It’s not hair, but an overgrowth of bacteria which may indicate poor oral hygiene. Pink patches Pink patches surrounded by a white border can make your tongue look like a map – this is called “<a href="https://www.mayoclinic.org/diseases-conditions/geographic-tongue/symptoms-causes/syc-20354396">geographic tongue</a>”. It’s <a href="https://www.mayoclinic.org/diseases-conditions/geographic-tongue/diagnosis-treatment/drc-20354401">not known</a> what causes this condition, which usually doesn’t require treatment. Pain and inflammation A red, sore tongue can indicate a <a href="https://medlineplus.gov/ency/article/003047.htm">range of issues</a>, including: <ul> <li>nutritional deficiencies such as folic acid or vitamin B12</li> <li>diseases including <a href="https://my.clevelandclinic.org/health/diseases/22377-pernicious-anemia">pernicious</a> anaemia, <a href="https://www.rch.org.au/kidsinfo/fact_sheets/kawasaki_disease/">Kawasaki disease</a> and <a href="https://www.childrens.health.qld.gov.au/health-a-to-z/scarlet-fever">scarlet fever</a></li> <li>inflammation known as <a href="https://www.ncbi.nlm.nih.gov/books/NBK560627/">glossitis</a></li> <li>injury from hot beverages or food</li> <li>ulcers, including cold sores and canker sores</li> <li><a href="https://www.nidcr.nih.gov/health-info/burning-mouth">burning mouth syndrome</a>.</li> </ul> Dryness Many medications can cause dry mouth, also called xerostomia. These include antidepressants, anti-psychotics, muscle relaxants, pain killers, antihistamines and diuretics. If your mouth is very dry, it may hurt. <h2>What about cancer?</h2> White or red patches on the tongue that can’t be scraped off, are long-standing or growing need to checked out by a dental professional as soon as possible, as do painless ulcers. These are at a <a href="https://oralcancerfoundation.org/cdc/premalignant-lesions/">higher risk</a> of turning into cancer, compared to other parts of the mouth. <a href="https://pubmed.ncbi.nlm.nih.gov/36852511/">Oral cancers</a> have low survival rates due to delayed detection – and they are on the rise. So <a href="https://youtu.be/Y6QkKhEjS5M">checking your tongue</a> for changes in colour, texture, sore spots or ulcers is <a href="https://www.dhsv.org.au/oral-health-programs/oral-cancer-screening-and-prevention">critical</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/237130/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/dileep-sharma-1562149">Dileep Sharma</a>, Professor and Head of Discipline - Oral Health, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Does eating ham, bacon and beef really increase your risk of developing type 2 diabetes?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/duane-mellor-136502">Duane Mellor</a>, <a href="https://theconversation.com/institutions/aston-university-1107">Aston University</a> That lunchtime staple, the humble ham sandwich, has come in for a bashing in the press recently. According to <a href="https://www.theguardian.com/society/article/2024/aug/20/two-slices-of-ham-a-day-can-raise-type-2-diabetes-risk-by-15-research-suggests">many</a> <a href="https://www.dailymail.co.uk/health/article-13761253/Eating-ham-daily-linked-increase-risk-diabetes.html">reports</a>, eating two slices of ham a day can increase your risk of developing type 2 diabetes. But what’s the science behind these headlines? The research offers a more complex picture. <a href="https://www.thelancet.com/journals/landia/article/PIIS2213-8587(24)00179-7/fulltext">A new study</a> from the University of Cambridge highlighted an association between developing type 2 diabetes and eating processed meat like ham and bacon, and red meat such as beef and lamb. This led to headlines suggesting the risk was mainly linked to <a href="https://www.telegraph.co.uk/news/2024/08/21/ham-sandwich-processed-meat-fresh-risk-link-type-2-diabetes/">ham sandwiches</a>. This seems to have come from the <a href="https://www.cam.ac.uk/research/news/red-and-processed-meat-consumption-associated-with-higher-type-2-diabetes-risk">press release</a>, which used ham as the example to quantify the amount of processed meat associated with a 15% increased risk of developing type 2 diabetes over ten years. The research found that this risk was linked to eating an extra 50g of processed meat every day, which happens to equate to two slices of ham. A useful example thus appears to have been taken up by the media as the main cause, perhaps ignoring some of the key messages coming from the study. So, can processed and red meat really increase your risk of developing type 2 diabetes? The <a href="https://www.diabetes.org.uk/diabetes-the-basics/types-of-diabetes/type-2/diabetes-risk-factors">biggest risk factors</a> linked to developing type 2 diabetes are being over 40, having family members with type 2 diabetes, being of South Asian or African descent, or having a higher body weight – and especially a larger waist. <figure><iframe src="https://www.youtube.com/embed/EsOBcx2bJqU?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> The Cambridge study used data from nearly 2 million people from 31 studies. Participants were followed for an average of ten years. During this time, around one in 20 people developed type 2 diabetes. The research suggested that a 10% increase in the probability of developing type 2 diabetes was associated with every 100g of additional red meat eaten daily. Eating half as much extra processed meat every day was linked to an even greater increased risk of developing the disease. This is not the <a href="https://ajcn.nutrition.org/article/S0002-9165(23)66119-2/abstract">first time</a> that both processed and red meats have been linked with an increased risk of developing type 2 diabetes. However, the key strength of the Cambridge study was that it tried to control for many of the other factors linked to the disease, including smoking, having a higher body weight, dietary intake and exercise. However, the size of the increased risk is modest, considering few people included in the study ate 50g or more processed meat per day – meaning moderate ham consumption is likely to have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9908545/">no meaningful effect</a> on your risk. <h2>What’s the link?</h2> Processed meat has been linked to increased risk of type 2 diabetes because of its nitrate and salt content – additives that are used to cure many processed meats. Nitrates and salt in processed meats have also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6893523/">been linked to</a> an increased risk of developing colon cancer. In fact, the World Health Organization classifies the additives as <a href="https://www.who.int/news-room/questions-and-answers/item/cancer-carcinogenicity-of-the-consumption-of-red-meat-and-processed-meat">group 1 carcinogens</a>, which means they can cause a range of cancers. The mechanism linking processed meat to cancer seems to be similar to how it might be linked to type 2 diabetes. During digestion, processed meat produces <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6294997/">N-nitroso chemicals</a>, which can damage cells. This can lead to inflammation and affects how insulin, the hormone that controls blood glucose (sugar), works. This in turn can lead to <a href="https://www.niddk.nih.gov/health-information/diabetes/overview/what-is-diabetes/prediabetes-insulin-resistance">insulin resistance</a>, when cells in your muscles, fat and liver don’t respond well to insulin and can’t easily take up glucose from your blood. Red meat, meanwhile, is <a href="https://www.healthline.com/nutrition/healthy-iron-rich-foods">rich in iron</a>. Research suggests that people with <a href="https://www.diabetes.org.uk/diabetes-the-basics/related-conditions/haemochromatosis-diabetes#:%7E:text=So%20a%20rise%20of%20iron,GP%20as%20soon%20as%20possible.">high levels of iron</a> are more likely to develop type 2 diabetes. However, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8744124/#:%7E:text=The%20WHO%20has%20recognised%20iron,being%20affected%20with%20this%20condition.">low levels of iron</a> are more of a health concern for the general population. Another potential link regarding red meat could be the way it is cooked. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5521980/">Previous studies</a> have suggested that charred meat, cooked over an open flame or at high temperature, is also linked to an increased risk of developing <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5911789/">type 2 diabetes</a>. Charring meat leads to formation of toxic chemicals such as <a href="https://www.sciencedirect.com/topics/pharmacology-toxicology-and-pharmaceutical-science/heterocyclic-amine#:%7E:text=Heterocyclic%20amines%20are%20aromatic%20compounds,of%20reactions%20called%20Maillard%20reactions.">heterocyclic aromatic amines</a> and harmful compounds like <a href="https://www.healthline.com/nutrition/advanced-glycation-end-products">advanced glycation end products</a>, both of which have been linked to <a href="https://pubmed.ncbi.nlm.nih.gov/21709297/">insulin resistance and type 2 diabetes</a>. <h2>Bye-bye barbecues and bacon butties?</h2> The key message is reduction, rather than avoidance. The UK government nutritional recommendations offer sound advice: limit your combined intake of red and processed meat to no more than <a href="https://www.nhs.uk/live-well/eat-well/food-types/meat-nutrition/#:%7E:text=Red%20meat%20and%20processed%20meat&text=If%20you%20currently%20eat%20more,%2C%20veal%2C%20venison%20and%20goat.">an average of 70g per day</a>. But these guidelines also suggest that red meat can be a valuable source of iron. So, if you decide to stop eating red meat, you should eat alternative sources of iron such as beans, lentils, dark green vegetables and fortified cereals. This needs to be done as part of a carefully planned diet. Non-meat sources of iron are more difficult for our bodies to absorb so should be eaten with a source of vitamin C, found in green vegetables and citrus fruit. The best advice to reduce your risk of developing type 2 diabetes is to maintain a healthy weight – consider losing weight if you have a higher body weight – and be as physically active as possible. A healthy diet should be based on plenty of vegetables, fruit, beans, peas, lentils, nuts and seeds, along with some wholegrain foods, some dairy products, fish and white meat (or vegetarian alternatives) – plus moderate amounts of red meat and minimal processed meat. This will help reduce your risk of type 2 diabetes, <a href="https://www.bhf.org.uk/informationsupport/support/healthy-living/healthy-eating">heart disease</a>, and <a href="https://www.cancerresearchuk.org/about-cancer/causes-of-cancer/diet-and-cancer/does-having-a-healthy-diet-reduce-my-risk-of-cancer">many cancers</a> – as well being more <a href="https://www.bda.uk.com/static/539e2268-7991-4d24-b9ee867c1b2808fc/a1283104-a0dd-476b-bda723452ae93870/one%20blue%20dot%20reference%20guide.pdf">environmentally sustainable</a>. But if you have a penchant for ham sandwiches, rest assured you can continue to indulge as an occasional treat. It’s your overall lifestyle and diet that really matter for your health and risk of developing type 2 diabetes.<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/237346/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/duane-mellor-136502">Duane Mellor</a>, Visiting Academic, Aston Medical School, <a href="https://theconversation.com/institutions/aston-university-1107">Aston University</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Jelena Dokic's candid admission on weight loss

Jelena Dokic has opened up on her 20kg weight loss and her previous struggles with depression and an eating disorder. The former tennis player took to Instagram on Sunday to share before and after shots from her weight loss, taken seven years apart, and her past battles with self-worth. She explained to her followers that her current weight loss was a result of her prioritising her mental health. "This is not about body size but feeling that I am not worthy enough to even live!!! On the left 7 years ago," she said. "Even though I have a bit less weight now on the right, this is not about weight. Because even if I was half the size on the left, I would still feel the same. And how is that? Not worthy enough to even live!!" She explained that in the first photo she was afraid to leave the house and was "broken" from her battle with depression and PTSD. "My face, body language and even clothing on the left says it all. This is how low my self worth was. I was afraid to get out of the house," she shared. "I was not able to look people in the eye, I just wanted to wear black or dark grey and cover myself up. I even remember wishing to somehow fully cover my face and head and could I possibly not even need to go out of the house for the rest of my life." "This was anxiety, depression, debilitating effect of trauma that made me feel I was worthless and not even worthy of living. "This was the result of being put down my whole life especially by people close to me." "The person on the left was broken, shattered, battling anxiety, depression, PTSD, BPD and an eating disorder. At times I hoped I wouldn't wake up so that I don't have to feel like this anymore," she continued. She then explained that she wasn't asking for pity as she didn't want to victimise herself. "I wanted to survive and thrive and I got there." She then shared a few motivating words on courage and resilience, saying: "Fight hard. Every single day, don't give up and no matter how scary it is get outside of your comfort zone. It will get easier and more comfortable to do so." "Keep going after it even when it's scary. Be brave and never give up. The way to start feeling good in your own skin and life is to be who you really are and embrace and love yourself." "Don't be afraid of mistakes and failures, they make you learn and as long as you get back up, that's all that matters." "Don't you ever give up on yourself and your goals. Don't ever be defined by someone else's judgement and comments." She encouraged her followers to stay true to themselves and remember their self-worth. "Be yourself. Being authentic, real and vulnerable is the way to being happy and thriving. You are worthy and never allow anyone to tell you otherwise." Images: Instagram

For a century, it’s been illegal to swim in the Seine. Will Paris’s clean-up make the river safe for Olympic swimmers?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/ian-a-wright-5162">Ian A. Wright</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> Five eagerly anticipated events in the Paris Olympics will be the mens and womens 10 kilometre marathon swimming races, as well as the 1,500 metre swimming section of three triathlon events. Why? Because all will be held in the Seine River in the centre of Paris. The swimmers – including <a href="https://www.swimmingworldmagazine.com/news/trio-complete-an-historic-australian-olympic-marathon-swim-team-for-paris-2024">four Australians</a> – will pass famous landmarks such as the Musee d'Orsay as they swim through the historic heart of the city. This will have enormous scenic appeal for spectators. But will it be safe for swimmers? Rivers running through large cities are <a href="https://www.nature.com/articles/s42949-021-00026-w">often polluted</a>, whether from stormwater, chemical pollution or wastewater spills. As the marathon swimmers pass the <a href="https://musee-egouts.paris.fr/en/">Paris Sewer Museum</a>, they may well wonder if they’re in clean water. For more than 100 years, swimming in the Seine has actually been illegal, due to concerns over what the water could do to human health. Authorities <a href="https://www.theguardian.com/sport/article/2024/may/24/olympic-games-clean-up-aims-to-leave-parisians-swimming-in-the-seine">have been working</a> to clean up the water, spending A$2.2 billion (€1.3 billion) on improving water quality. The goal: cut bacterial contamination by 75% before the first swimmer touches the water. These measures are having an impact – but recent heavy rains have seen bacteria levels spike. While officials have put on brave faces, there’s now a <a href="https://www.reuters.com/sports/olympics/paris-2024-sets-up-reserve-site-marathon-swimming-if-seine-unsuitable-2024-07-05/">contingency plan</a> in case the Seine isn’t safe. <h2>Why swim in the Seine at all?</h2> Urban rivers have a questionable reputation. But this isn’t the first time the Seine River has been used for Olympic swimming. In the 1900 Paris Olympics, <a href="https://olympics.com/en/olympic-games/paris-1900/results/swimming">seven swimming events</a> were all held in the river. These games were the first modern Olympics where <a href="https://olympics.com/ioc/faq/history-and-origin-of-the-games/when-did-women-first-compete-in-the-olympic-games">women could compete</a> in some sports, but swimming was not one of those permitted. The Australian swimmer who competed, Frederick Lane, had to swim under the United Kingdom’s flag as Australia did not have a flag until Federation the following year. He won two gold medals. One was for the 200 metre freestyle race, and the other for a bizarre race never held again: the 200m <a href="https://www.olympedia.org/results/4433">swimming obstacle race</a>, where swimmers had to climb over poles and boats. These Olympics also saw the first and last underwater swimming race, which was also in the Seine. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/606823/original/file-20240715-17-kajph6.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/606823/original/file-20240715-17-kajph6.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/606823/original/file-20240715-17-kajph6.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=378&fit=crop&dpr=1 600w, https://images.theconversation.com/files/606823/original/file-20240715-17-kajph6.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=378&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/606823/original/file-20240715-17-kajph6.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=378&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/606823/original/file-20240715-17-kajph6.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=475&fit=crop&dpr=1 754w, https://images.theconversation.com/files/606823/original/file-20240715-17-kajph6.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=475&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/606823/original/file-20240715-17-kajph6.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=475&fit=crop&dpr=3 2262w" alt="historic photo swimming seine river paris" /></a><figcaption>Swimmers took to the Seine’s waters at the 1900 Paris Olympics, when the river ran cleaner. <a class="source" href="https://commons.wikimedia.org/wiki/File:Swimming_1900.jpg">Wikimedia Commons</a>, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></figcaption></figure> Back then, the waters of the Seine were cleaner. That’s because there was a great demand for human waste on farms – and cities were the main source. Back then, “night soil” (human waste) had a <a href="https://hess.copernicus.org/articles/11/1757/2007/hess-11-1757-2007.pdf">real market value</a>. No one would think of dumping it in rivers. But as time went on, sewerage systems developed and other fertilisers such as guano and mineral fertilisers arrived. By the early 20th century, most of the city’s wastewater went into the Seine. In 1923, the swimming ban came into effect. A year later, Paris hosted the Olympics for its second time – and swimmers competed in 50 metre pools. In recent years, many cities around the world have worked to clean up their urban waterways. River swimming is <a href="https://www.timeout.com/news/the-european-cities-cleaning-up-rivers-for-wild-swimmers-101821">now common</a> in cities such as Copenhagen, Berlin and Vienna, where river health has improved dramatically. <h2>How can you clean a river like the Seine?</h2> Cleaning the Seine is a challenge. Paris is home to 11 million people, with plenty of industry. Urban rivers are almost inevitably polluted by waste from the <a href="https://www.nature.com/articles/s42949-021-00026-w%5D">surrounding city</a>. Leaking and overflowing sewage systems are a major source of pollution. In places like the UK, <a href="https://www.bbc.com/news/explainers-62631320">sewage spills</a> into waterways have become a major political issue. When wastewater spills into rivers, it carries pollutants and dangerous loads of <a href="https://www.cdc.gov/mmwr/volumes/67/wr/mm6725a1.htm">disease-causing microorganisms</a>, such as Escherichia coli (commonly known as E. coli). Untreated water can have viruses, bacteria and disease-causing protozoa. In the lead-up to the Paris games, authorities have been working to improve water quality enough to bring some Olympic swimming back to the Seine. Stormwater – often contaminated by dog poo or sewage overflows – is <a href="https://www.theguardian.com/environment/2023/oct/08/can-paris-clean-seine-for-next-year-2024-olympics">being cleaned</a> before it is released into the river. Despite the money and effort, there are still real questions over whether it will be enough to guarantee swimmer safety. Bacterial levels hit risky levels <a href="https://edition.cnn.com/2024/07/11/sport/paris-olympics-seine-triathlon-bacteria-spiking-intl/index.html">most days in June</a> due to unseasonally heavy rains, but the water has <a href="https://www.france24.com/en/france/20240712-seine-clean-enough-to-swim-for-most-of-past-12-days-paris-says-ahead-of-olympics">improved in July</a>. This week, French sports minister Amélie Oudéa-Castéra <a href="https://www.nbclosangeles.com/paris-2024-summer-olympics/french-sports-minister-takes-dip-in-seine-river-2024-paris-olympics/3458469/">swam a few metres</a> in the Seine in an effort to douse concerns. By contrast, the other Olympic swimming events will take place in a recently constructed 50 metre pool, which will have very good water quality. The pool water is filtered and treated with a disinfectant such as chlorine or bromine. It will be regularly tested to ensure optimal water quality. At the Tokyo 2020 Olympics, triathletes had to swim in polluted Tokyo Bay. But similar concerns over sickness proved unfounded. The real challenge was the <a href="https://www.theguardian.com/environment/2021/aug/05/olympic-athletes-and-volunteers-in-tokyo-tortured-by-heat">oppressive heat</a>. <h2>What’s at risk?</h2> The most likely outcome if races are held when bacterial levels are unsafe would be getting a gastrointestinal bug. Officials have some control over this. Contamination is worst after heavy rain. Races could be delayed if need be. Many swimmers – especially those who compete in open-water competitions – are familiar with swimming in water with some level of pollution. Some see it as worth the risk. Italian double world champion swimmer Gregorio Paltrinieri <a href="https://www.france24.com/en/live-news/20240226-paris-holds-its-breath-for-olympic-swimming-events-in-murky-seine">said in January</a>: <blockquote> Even if the water is dirty, I would rather swim in an electric atmosphere in the centre of Paris than in an anonymous stretch of water. </blockquote> Paris 2024 organisers previously warned there was no plan B for the 10 km marathon races in the Seine if water quality testing is unsuitable. But this has now changed. If the river isn’t clean enough, open water swimming <a href="https://www.reuters.com/sports/olympics/paris-2024-sets-up-reserve-site-marathon-swimming-if-seine-unsuitable-2024-07-05/">will be moved</a> to the rowing venue. The Olympic triathlon is planned around a swimming leg in the Seine. But triathletes <a href="https://www.espn.com.au/olympics/story/_/id/39912675/triathlon-leg-cancelled-seine-quality-paris-2024-chief">have been told</a> the swim leg could be skipped if the water is unsafe, which would turn the race into a running and cycling duathlon. As the world’s attention turns to Paris, there will be many anxious officials behind the scenes hoping their hard work on making the Seine swimmable pays off.<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/231705/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/ian-a-wright-5162">Ian A.

Travel Trouble

We know what to eat to stay healthy. So why is it so hard to make the right choices?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/nina-van-dyke-822557">Nina Van Dyke</a>, <a href="https://theconversation.com/institutions/victoria-university-1175">Victoria University</a> A healthy diet <a href="https://www.who.int/initiatives/behealthy/healthy-diet">protects us</a> against a number of chronic diseases, including heart disease, diabetes and cancer. From early childhood, we receive an abundance of <a href="https://cdn.who.int/media/docs/default-source/healthy-diet/healthy-diet-fact-sheet-394.pdf?sfvrsn=69f1f9a1_2&download=true">information</a> about how we <a href="https://www.eatforhealth.gov.au/guidelines/australian-guide-healthy-eating">should eat</a> to be healthy and reduce our risk of disease. And most people have a <a href="https://link.springer.com/content/pdf/10.1186/1479-5868-11-63.pdf">broad understanding</a> of what healthy eating looks like. But this knowledge <a href="https://www.sciencedirect.com/science/article/pii/S0001209216310584?casa_token=6CZgCmT1RMgAAAAA:sSRsj2o6swVfvoBxMIVrMTxqdczSAiFwfTCYzYQ8U3z4ey_WLQ6knpmk8WRH77zugAS3wEAQrA">doesn’t always result</a> in healthier eating. In our new research, we set out to <a href="https://link.springer.com/content/pdf/10.1186/s12889-024-18432-x.pdf">learn more</a> about why people eat the way they do – and what prevents them from eating better. Lack of time was a major <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1111/obr.12472?casa_token=1D1mi-l0TR0AAAAA:dgebTQx-wgw7jbREfdawxZ5AZSDRztvrt8t1tuKyDy1x2mmXlyLDY8z9NbUf0v4hnh80HY_RbAk08Q">barrier</a> to cooking and eating healthier foods. <h2>How do you decide what to eat?</h2> We spoke with <a href="https://link.springer.com/content/pdf/10.1186/s12889-024-18432-x.pdf">17 adults</a> in a regional centre of Victoria. We chose a regional location because less research <a href="https://link.springer.com/content/pdf/10.1186/s40900-020-0179-6.pdf">has been done</a> with people living outside of metropolitan areas and because rates of obesity and other diet-related health issues are <a href="https://www.aihw.gov.au/reports/rural-remote-australians/rural-and-remote-health">higher</a> in such areas in Australia. Participants included a mix of people, including some who said they were over their “most healthy weight” and some who had previously dieted to lose weight. But all participants were either: <ul> <li>young women aged 18–24 with no children</li> <li>women aged 35–45 with primary school aged children</li> <li>men aged 35–50 living with a partner and with pre- or primary-school aged children.</li> </ul> We selected these groups to target <a href="https://www.sciencedirect.com/science/article/pii/S0022318212803669">ages and life-stages</a> in which shifts in eating behaviours may occur. Previous research has found younger women <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1111/j.1470-6431.2007.00642.x?casa_token=33QKWwhc2ogAAAAA:ZvJ6wfXiRC_6eoqvoxD121JOSKSPmIRHcrdiGl2uHzkq5pY6VVPL6WI2DhmxQ2q9i6bBGvLiFl8afQ">tend to</a> be particularly concerned about appearance rather than healthy eating, while women with children often shift their focus to providing for their family. Men <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1111/obr.12472?casa_token=KakMB6hAOQ0AAAAA:fLnpoxZQiiJIdEkg_TOcCq8hBwZef1iZETZKTiG5W6zW2x_PYzK0oLeOg5F9arKThq9RzMWEi4x4Xw">tend to be less interested</a> in what they eat. We asked participants about how they decided what food to eat, when, and how much, and what prevented them from making healthier choices. <h2>It’s not just about taste and healthiness</h2> We found that, although such decisions were determined in part by taste preferences and health considerations, they were heavily influenced by a host of other factors, many of which are outside the person’s control. These included other household members’ food preferences, family activities, workplace and time constraints, convenience and price. <a href="https://jamanetwork.com/journals/jamainternalmedicine/article-abstract/2767106">Healthy eating</a> means consuming a balanced diet rich in nutrients, including a variety of fruits, vegetables, whole grains, lean proteins and healthy fats, while limiting processed foods, added sugars and excessive salt. Healthy eating also includes how we eat and <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0244292">how we think about</a> food and eating, such as having a positive relationship with food. One 35- to 45-year-old woman, for example, said that time constraints and family preferences made it difficult to prepare healthier food: <blockquote> I love the chance when I can actually get a recipe and get all of the ingredients and make it properly, but that doesn’t happen very often. It’s usually what’s there and what’s quick. And what everyone will eat. </blockquote> One of the 35- to 50-year-old men also noted the extent to which family activities and children’s food preferences dictated meal choices: <blockquote> Well, we have our set days where, like Wednesday nights, we have to have mackie cheese and nuggets, because that’s what the boys want after their swimming lesson. </blockquote> <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1111/joss.12649?casa_token=gsnU9O_G2GQAAAAA:mV2vtHlnEd0jqBGJPFkfml_ecLIDqwSlH5xksSwt4eQb_FP_UShyAKm9sLNnKy6Mkf2q9aKAlDEixA">Research shows</a> that children are often more receptive to new foods than their parents think. However, introducing new dishes takes additional time and planning. An 18- to 24-year-old woman discussed the role of time constraints, her partner’s activities, and price in influencing what and when she eats: <blockquote> My partner plays pool on a Monday and Wednesday night, so we always have tea a lot earlier then and cook the simple things that don’t take as long, so he can have dinner before he goes rather than buying pub meals which cost more money. </blockquote> Despite popular perceptions, healthy diets are not more expensive than unhealthy diets. A <a href="https://preventioncentre.org.au/wp-content/uploads/2017/03/1702_FB_LEE_4p_final_lr.pdf">study</a> comparing current (unhealthy) diets with what the <a href="https://www.health.gov.au/resources/publications/the-australian-dietary-guidelines">Australian Dietary Guidelines</a> recommend people should eat found that the healthy diet was 12–15% cheaper than unhealthy diets for a family of two adults and two children. However, learning and planning to prepare new types of meals <a href="https://www.mdpi.com/2072-6643/12/3/877">takes effort and time</a>. Simply educating people about what they should eat won’t necessarily result in healthier eating. People want to eat healthier, or at least know they should eat healthier, but other things <a href="https://link.springer.com/content/pdf/10.1007/s00394-017-1458-3.pdf">get in the way</a>. A key to improving people’s eating behaviours is to make it easy to eat more healthily. Policy changes to make healthy eating easier could include subsidising healthier foods such as fresh produce, providing incentives for retailers to offer healthy options, and ensuring access to nutritious meals in schools and workplaces. <h2>So how can you make healthier food choices easier?</h2> Here are five tips for making healthy choices easier in your household: <ol> <li> If certain days of the week are particularly busy, with little time to prepare fresh food, plan to cook in bulk on days when you have more time. Store the extra food in the fridge or freezer for quick preparation. </li> <li> If you’re often pressed for time during the day and just grab whatever food is handy, have healthy snacks readily available and accessible. This could mean a fruit bowl in the middle of the kitchen counter, or wholegrain crackers and unsalted nuts within easy reach. </li> <li> Discuss food preferences with your family and come up with some healthy meals everyone likes. For younger children, <a href="https://healthykids.nsw.gov.au/downloads/file/campaignsprograms/NewFoodsFussyEaters.pdf">try serving</a> only a small amount of the new food, and serve new foods alongside foods they already like eating and are familiar with. </li> <li> If you rely a lot on take-away meals or meal delivery services, try making a list ahead of time of restaurants and meals you like that are also healthier. You might consider choosing lean meat, chicken, or fish that has been grilled, baked or poached (rather than fried), and looking for meals with plenty of vegetables or salad. </li> <li> Remember, fruit and vegetables taste better and are often cheaper when they are in season. Frozen or canned vegetables are a <a href="https://www.sbs.com.au/news/article/the-cost-of-fresh-fruit-and-veggies-is-rising-is-canned-or-frozen-produce-just-as-healthy/tzuhnfrnr">healthy and quick alternative</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/231489/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> </li> </ol> <a href="https://theconversation.com/profiles/nina-van-dyke-822557">Nina Van Dyke</a>, Associate Professor and Associate Director, Mitchell Institute, <a href="https://theconversation.com/institutions/victoria-university-1175">Victoria University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Will watching the Olympic Games make you eat more?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/birau-mia-1238429">Birau Mia</a>, <a href="https://theconversation.com/institutions/em-lyon-business-school-2363">EM Lyon Business School</a> and <a href="https://theconversation.com/profiles/carolina-o-c-werle-1434243">Carolina O.C. Werle</a>, <a href="https://theconversation.com/institutions/grenoble-ecole-de-management-gem-2181">Grenoble École de Management (GEM)</a> Ever wondered why you reach for a snack after hitting the gym? <a href="https://joe.bioscientifica.com/downloadpdf/view/journals/joe/193/2/1930251.pdf">Research shows</a> that physical exercise often leads to increased food consumption, whether it is treating yourself for a job well done or replenishing the energy you have burned. With countless sports events airing and our screens constantly filled with sports’ competitions, a new question arises: Can watching sports on a screen also influence how much we eat? The answer is yes. <a href="https://www.sciencedirect.com/science/article/pii/S0950329317300915">Our research</a> co-authored with <a href="https://www.linkedin.com/in/jannine-lasaleta-94504987">Jannine Lasaleta</a> reveals that watching sports’ videos can increase candy consumption. But there is more to the story: the difficulty of the sports you are watching plays a crucial role in these effects. <h2>From screens to junk food</h2> We first invited 112 students to the <a href="https://www.grenoble-em.com/campus-gem-labs-grenoble">Grenoble Ecole de Management experimental lab</a> to watch a video and test some candies. Half of the students watched a video with men and women <a href="https://fr.adforum.com/creative-work/ad/player/51706/train-barefoot/nike">playing sports</a>, while the other half watched one <a href="https://www.youtube.com/watch?v=xyqR5yI6boo">without any physical activity</a>. We then gave each student a 70g cup of candy and asked them to judge its quality for three minutes. The students who saw the sports’ video ate more candy than those who saw the one without physical activity. Our initial test thus revealed that watching sports’ videos can boost candy consumption, but here’s the twist: male students indulged in far more candy than female students, so maybe the results were triggered by males’ consumption. Plus, we were still unsure if the type of sport watched affects the candy intake. To learn more, we invited just the female students to watch videos portraying either easy (light running) or difficult-to-perform sports (athletics long jump, gymnastics, baseball, rugby or rock climbing). After, the students were invited to test the same candies as before. Students who watched the <a href="https://www.youtube.com/watch?v=2SMXKGE_u-Y">easy sports video</a> (showing a woman and a man running through different landscapes) ate much more candy (30.1 grams) than those who watched the <a href="https://fr.adforum.com/creative-work/ad/player/51706/train-barefoot/nike">difficult sports video</a> (18 grams). We can thus conclude that the ease or difficulty of the exercise shown significantly impacts candy consumption – watching easy-to-perform sports leads to considerably higher candy intake than watching difficult ones. <h2>Why is this happening?</h2> To explain our findings, we looked at research on <a href="https://academic.oup.com/jcr/article-abstract/32/3/370/1867208">goal motivation</a>. When people feel they are not meeting a goal, they push harder; but once they see progress, they tend to slack off. For example, after a workout, those aiming to stay fit might feel they have made good progress and then ease up on their efforts. This can lead to a drop in motivation to pursue related goals, like healthy eating. <a href="https://psycnet.apa.org/record/2006-09808-003">Research</a> shows that achieving smaller goals (like exercising) can make people feel they have earned a break, which can result in indulging more in food. So completing a workout might make you more likely to reward yourself with extra food than if you had not finished your session. And why are women more susceptible to the phenomenon of eating more candy after watching an easy-to-perform sports video? Simply because it has been long <a href="https://phys.org/news/2005-04-women-weight-men.html">shown</a> that women are more concerned with their weight than men and therefore their dieting goals are more salient. Our research suggests that merely watching sports can lead to a sense of vicarious fulfilment of fitness goals. When people can picture themselves doing the activity they are watching, they feel as though they have already exercised, which can lead to more-indulgent food choices. If they perceive the exercise shown as easy rather than difficult, they can more easily imagine themselves doing it, leading to greater feelings of progress toward their fitness goals. This perceived achievement can make them feel they have earned the right to indulge and influence their search for a reward, often resulting in increased food intake. <h2>So what?</h2> This knowledge can be used by policymakers or marketers who aim to encourage healthful lifestyles. When promoting healthy activities by picturing physical activity that seems too easy, people may feel a greater sense of achievement that could backfire and lead to increased consumption. We suggest showing an easy exercise (like walking or jogging) followed by a tougher one (like sprinting or marathon running) as an alternative solution. This approach can motivate people to start with basic exercises while reminding that there is still a long way to go to reach their fitness goals. This strategy could offer an alternative to promote physical activity without giving a false sense of accomplishment. So what is the takeaway for us? Be mindful of how watching sports can affect our eating habits. If you are aiming to stay on track with your diet, watch more challenging sports – it might just help you resist that extra chocolate bar. Moreover, when setting dieting goals, remind yourself that real progress comes from consistent effort, not just imagining yourself doing a workout. Engage in activities that genuinely challenge you, and pair them with mindful eating habits. This way, you can avoid the trap of feeling the fitness goal to be prematurely accomplished and then overindulging. In conclusion, should you watch the Olympic games if you want to keep up with your diet? Of course, but it might be better to choose the physical activities you find the most difficult to perform – and watch them without moderation.<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/231199/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/birau-mia-1238429">Birau Mia</a>, Associate Professor of Marketing, <a href="https://theconversation.com/institutions/em-lyon-business-school-2363">EM Lyon Business School</a> and <a href="https://theconversation.com/profiles/carolina-o-c-werle-1434243">Carolina O.C.

“Grief eats you away”: Prince Harry's candid interview about losing his mother

Prince Harry has spoken candidly about his ongoing struggles with grief following the death of his mother, the late Princess Diana, when he was just 12 years old. Upon his brief return to the UK, the Duke of Sussex opened up in a new interview as part of his role as global ambassador for Armed Forces charity Scotty’s Little Soldiers, who work to support children who have lost parents in the military, admitting that “grief eats you away”. Harry detailed how difficult it was losing his mother at such a young age, admitting he spent nearly two decades “not thinking” about her death and was forced to eventually get help after years of “total chaos”. He added that learning how to celebrate a late loved one is difficult for a child, as it made them “sad”. “But realising if I do talk about it, and I’m celebrating their life, then things become easier,” he said. Harry went on, “You convince yourself that the person you’ve lost wants you, or you need to be sad for as long as possible to prove to them that they are missed … Especially when every defence mechanism in your mind, nervous system and everything else is saying ‘do not go there.” <iframe title="YouTube video player" src="https://www.youtube.com/embed/YY-W6VEXlZM?si=SBQyGGCKAOhELxlv" width="560" height="315" frameborder="0" allowfullscreen="allowfullscreen"></iframe> "But then there’s this realisation of, no, they must want me to be happy”. The 39-year-old royal shared how, after decades of silent mourning, he learned suppressing grief was “in fact not” the best form of coping with loss. “It can be for a period of time,” he went on to say. “But…if you suppress this for too long, you can’t suppress it forever it’s not sustainable and it will east away at you inside." “Once realising that if I do talk about it and I’m celebrating their life then actually things become easier.” Image credits: YouTube

5 ways to fake a clean bathroom

Got a friend popping around for a catch up, and, your bathroom is less than sparkling? Don’t stress. Follow our foolproof tips to fake it so no one knows you didn’t have time to do a proper clean. 1. Scrub the loo The toilet is often a telltale sign that your bathroom is in need of a clean. If you haven’t already invested in a leave-in cleaner for your bowl, simply get in there with some toilet cleaner and give a good squirt under the rim. Leave it to do its job while you get on with the rest of the bathroom. Then when it’s had a few minutes to soak, give it a once over with the toilet brush. Grab some toilet paper (or an antibacterial wipe) and give the rim and the top of the toilet a once over to remove any dust. 2. Eliminate any obvious mould and grime Find yourself some good-quality mould spray that you can apply and then leave to work its magic while you move on to other areas of the bathroom. After 10 minutes (check your packet for the optimal time) you should be able to spray it with warm water from the shower and then wipe it clean. 3. Do a quick dust bust Grab yourself a clean cloth or antibacterial wipe and go over the shelves and basin to get rid of any dust or dirt you can see. 4.Change your bathmat and hand towel There’s nothing like a fresh and clean bathmat to trick your guests into thinking that you’ve just finished scrubbing the bathroom. Add a clean hand towel to complete the look. 5.Add a sweet scent Give your bathroom a look of freshness by popping a small vase of flowers in there. You can also try a scented candle on top of the toilet to give off a nice scent and hide any odours. Image credits: Shutterstock

5 ways your sleep affects what you eat

We know a good night’s sleep is good for us but logging in those hours of sleep can be a difficult task. Without quality shut-eye, our productivity decreases, immune system weakens and even our dietary health is negatively affected. You eat more when you sleep less A Mayo Clinic study comparing the eating habits of people who slept as much as they needed and those who only slept two-thirds of their required rest time for eight days, found the subject who were sleep-deprived ended up eating an average of 549 extra calories each day. You snack more, especially at night A lack of sleep can lead to decrease in physical activity and an increase in snacking behaviour. Such behaviours typically leads to weight gain. You crave extra carbs and fatty foods The foods we’re snacking on aren’t usually the healthy variety. A 2013 study found that when we’re tired we not only crave unhealthy, -carbohydrate, and high-fat foods but we’re less likely to consider the consequences of such food choices over time. Disrupted sleep cycle equal changing eating patterns Your internal clock guides both your sleep patterns and your eating patterns – aka when you feel hungry during the day. A 2011 study found that people who are “late sleepers” tend to delay their meals throughout the day and end up consuming more calories than the average meal. Those late-eating habits affect sleep and perpetuates the cycle. You don’t eat the right foods A 2013 study found that sleep-deprived subjects ate half the fruit and vegetable servings of a normal sleeper. This meant losing key nutrients from their diet, which can lead to dietary imbalances and effect the regular functioning of the body. Image credits: Shutterstock

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.

Eating some chocolate really might be good for you – here’s what the research says

<a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> Although it always makes me scoff slightly to see Easter eggs making their first appearance in supermarkets at the end of December, there are few people who aren’t delighted to receive a bit of chocolate every year. It makes sense that too much chocolate would be bad for you because of the high fat and sugar content in most products. But what should we make of common claims that eating some chocolate is actually good for you? Happily, there is a fair amount of evidence that shows, in the right circumstances, chocolate may be both beneficial for your heart and good for your mental state. In fact, chocolate – or more specifically cacao, the raw, unrefined bean – is a medicinal wonder. It contains many different active compounds which can evoke pharmacological effects within the body, like medicines or drugs. Compounds that lead to neurological effects in the brain have to be able to cross the <a href="https://link.springer.com/chapter/10.1007/978-3-642-13443-2_7">blood-brain barrier</a>, the protective shield which prevents harmful substances – like toxins and bacteria – entering the delicate nervous tissue. One of these is the compound <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3672386/">theobromine</a>, which is also found in tea and contributes towards its bitter taste. Tea and chocolate also contain caffeine, which theobromine is related to as part of the purine family of chemicals. These chemicals, among others, contribute to chocolate’s addictive nature. They have the ability to cross the blood-brain barrier, where they can influence the nervous system. They are therefore known as <a href="https://pubmed.ncbi.nlm.nih.gov/15549276/">psychoactive</a> chemicals. <figure><iframe src="https://www.youtube.com/embed/HloqayQdR6M?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> What effects can chocolate have on mood? Well, <a href="https://academic.oup.com/nutritionreviews/article/71/10/665/1931144?login=false">a systematic review</a> looked at a group of studies which examined the feelings and emotions associated with consuming chocolate. Most demonstrated improvements in mood, anxiety, energy and states of arousal. Some noted the feeling of guilt, which is perhaps something we’ve all felt after one too many Dairy Milks. <h2>Health benefits of cocoa</h2> There are other organs, aside from the brain, that might benefit from the medicinal effects of cocoa. For centuries, chocolate has been used as a medicine to treat a <a href="https://pubmed.ncbi.nlm.nih.gov/10917925/">long list of diseases</a> including anaemia, tuberculosis, gout and even low libido. These might be spurious claims but there is evidence to suggest that eating cacao has a positive effect on the cardiovascular system. First, it can prevent <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8068178/">endothelial dysfunction</a>. This is the process through which arteries harden and get laden down with fatty plaques, which can in turn lead to heart attacks and strokes. Eating dark chocolate may also reduce <a href="https://www.sciencedirect.com/science/article/pii/S1537189115001135?via%3Dihub">blood pressure</a>, which is another risk factor for developing arterial disease, and prevent formation of clots which block up blood vessels. <figure><iframe src="https://www.youtube.com/embed/8VUcPCbSSCY?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> Some studies have suggested that dark chocolate might be useful in adjusting ratios of <a href="https://pubmed.ncbi.nlm.nih.gov/20968113/">high-density lipoprotein cholesterol</a>, which can help protect the heart. Others have examined insulin resistance, the phenomenon associated with Type 2 diabetes and weight gain. They suggest that the <a href="https://www.sciencedirect.com/science/article/pii/S0963996900000697#:%7E:text=Cocoa%20is%20rich%20in%20polyphenols%20particularly%20in%20catechins,and%20cocoa%20powder%20have%20been%20published%20only%20recently.">polyphenols</a> – chemical compounds present in plants – found in foodstuffs like chocolate may also lead to <a href="https://pubmed.ncbi.nlm.nih.gov/29993262/">improved control of blood sugars</a>. <h2>Chocolate toxicity</h2> As much as chocolate might be considered a medicine for some, it can be a poison for others. It’s well documented that the ingestion of caffeine and theobromine is highly toxic for domestic animals. Dogs are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4801869/">particularly affected</a> because of their often voracious appetites and generally unfussy natures. The culprit is often dark chocolate, which can provoke symptoms of agitation, rigid muscles and even seizures. In certain cases, if ingested in high enough quantities, it can lead to comas and abnormal, even fatal heart rhythms. Some of the compounds found in chocolate have also been found to have potentially negative effects in humans. Chocolate is a source of oxalate which, along with calcium, is one of the main components of <a href="https://pubmed.ncbi.nlm.nih.gov/20301742/">kidney stones</a>. Some clinical groups have advised against consuming oxalate rich foods, such as spinach and rhubarb – and chocolate, for those who suffer from recurrent kidney stones. So, what should all this mean for our chocolate consumption habits? Science points in the direction of chocolate that has as high a cocoa solid content as possible, and the minimum of extras. The potentially harmful effects of chocolate are more related to fat and sugar, and may counteract any possible benefits. A daily dose of 20g-30g of plain or dark chocolate with cocoa solids above 70% – rather than milk chocolate, which contains fewer solids and white chocolate, which contains none – could lead to a greater health benefit, as well as a greater high. But whatever chocolate you go for, please don’t share it with the dog.<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/226759/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/dan-baumgardt-1451396">Dan Baumgardt</a>, Senior Lecturer, School of Physiology, Pharmacology and Neuroscience, <a href="https://theconversation.com/institutions/university-of-bristol-1211">University of Bristol</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Vinegar and baking soda: a cleaning hack or just a bunch of fizz?

<a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> Vinegar and baking soda are staples in the kitchen. Many of us have combined them in childhood scientific experiments: think fizzy volcanoes and geysers. But people also frequently mix vinegar and baking soda to produce a reportedly effective household cleaner. Unfortunately, the chemistry behind the bubbly reaction doesn’t support the cleaning hype. The fizzy action is essentially <a href="https://theconversation.com/six-surprising-things-about-placebos-everyone-should-know-220829">a visual “placebo</a>”, formed by the combination of an acid and a base. So, how does it work, and is it worth using these chemicals for cleaning? To understand all this, it helps to know a little more about chemistry. <h2>What’s an acid?</h2> Foods with a sour taste typically contain acids. These include citric acid in lemon juice, malic acid in apples, lactic acid in yoghurt and <a href="https://theconversation.com/kitchen-science-everything-you-eat-is-made-of-chemicals-56583">phosphoric acids in soft drinks</a>. Most vinegars contain around 4–10% acetic acid, the rest is water and small amounts of flavour chemicals. There are other naturally occurring acids, such as formic acid in ant bites and hydrochloric acid in our stomachs. Industrially, sulfuric acid is used in mineral processing, nitric acid for <a href="https://theconversation.com/what-is-ammonium-nitrate-the-chemical-that-exploded-in-beirut-143979">fertiliser manufacturing</a> and the highly potent hydrofluoric acid is used to etch glass. All of these acids share similar properties. They can all release hydrogen ions (positively charged atoms) into water. Depending on their potency, acids can also dissolve minerals and metals through various chemical reactions. This is why vinegar is an excellent cleaner for showers or kettles – it can react with and dissolve mineral deposits like limescale. Other common acidic cleaning ingredients are oxalic acid, used for revitalising timber decks, hydrochloric acid in concrete and masonry cleaners, and sulfamic acid in potent toilet cleaners. <h2>What’s a base?</h2> In chemistry, bases – the opposite of acids in many ways – can bind, rather than release hydrogen ions. This can help lift and dissolve insoluble grime into water. Bases can also break apart fat molecules. Baking soda (also known as sodium hydrogen carbonate, sodium bicarbonate, or bicarb) is a relatively weak base. Stronger common bases include sodium carbonate (washing soda), sodium hydroxide (lye) and ammonia. <a href="https://theconversation.com/spill-at-a-nuclear-facility-shows-potential-burn-risks-from-a-household-chemical-112763">Sodium hydroxide</a> is a potent drain cleaner – its strong base properties can dissolve fats and hair. This allows blockages to be broken down and easily flushed away. <h2>Mixing a base and an acid</h2> Mixing vinegar and baking soda causes an immediate chemical reaction. This reaction forms water, sodium acetate (a salt) and carbon dioxide – the fizzy part. The amount of carbon dioxide gas that is produced from baking soda is remarkable – one tablespoon (around 18 grams) can release over <a href="https://www.chemedx.org/JCESoft/jcesoftSubscriber/CCA/CCA8/MAIN/8/06/2/4/movie.html">five litres of gas</a>! But only if you add enough acid. Reactions in chemistry often use equal quantities of chemical reagents. A perfect balance of acetic acid and baking soda would give you just water, carbon dioxide and sodium acetate. But the majority of vinegar and bicarb cleaner recipes use a large excess of one or the other components. An example from TikTok for a DIY oven cleaner calls for one and a half cups of baking soda and one quarter cup of vinegar. Crunching the numbers behind the chemical reaction shows that after the fizz subsides, over 99% of the added baking soda remains. So the active cleaning agent here is actually the baking soda (and the “elbow grease” of scrubbing). Ovens can be cleaned much more rigorously with stronger, sodium hydroxide based cleaners (although these are also more caustic). Many modern ovens also have a self-cleaning feature, so read your product manual before reaching for a chemical cleaner of any sort. <h2>What about the sodium acetate?</h2> Devotees of vinegar and baking soda mixtures might be wondering if the product of the fizzy reaction, sodium acetate, is the undercover cleaning agent. Unfortunately, sodium acetate is an even weaker base than baking soda, so it doesn’t do much to clean the surface you’re trying to scrub. Sodium acetate is used in <a href="https://www.youtube.com/watch?v=vABpel-11Nc">crystallisation-based heating packs</a> and as a concrete sealant, but not typically as a cleaner. Fun fact: sodium acetate can be combined with acetic acid to make a crystalline <a href="https://theconversation.com/busting-the-myth-that-all-food-additives-are-bad-a-quick-guide-for-label-readers-82883">food additive</a> called sodium diacetate. These crystals give the vinegar flavour to <a href="https://www.youtube.com/watch?v=N0hEutu_goY">salt and vinegar chips</a> without making them soggy. <h2>Sorry to burst your bubbles</h2> There are a few rare cases where mixing vinegar and baking soda may be useful for cleaning. This is where the bubbling has a mechanical effect, such as in a blocked drain. But in most cases you’ll want to use either vinegar or baking soda by itself, depending on what you’re trying to clean. It will be less <a href="https://theconversation.com/visually-striking-science-experiments-at-school-can-be-fun-inspiring-and-safe-banning-is-not-the-answer-195362">visually exciting</a>, but it should get the job done. Lastly, remember that mixing cleaning chemicals at home can be risky. Always carefully read the product label and directions before engaging in DIY concoctions. And, to be extra sure, you can find out more safety information by reading the product’s <a href="https://theconversation.com/a-new-tiktok-trend-has-people-drinking-toxic-borax-an-expert-explains-the-risks-and-how-to-read-product-labels-210278">safety data sheet</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/225177/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, Senior Lecturer in Chemistry, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Here’s why having chocolate can make you feel great or a bit sick – plus 4 tips for better eating

<a href="https://theconversation.com/profiles/saman-khalesi-366871">Saman Khalesi</a>, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a> Australians are <a href="https://www.retail.org.au/media/sweet-spending-boon-predicted-for-easter-retail">predicted</a> to spend around A$1.7 billion on chocolates, hot cross buns and other special foods this Easter season. Chocolate has a long history of production and consumption. It is made from cacao beans that go through processes including fermentation, drying, roasting and grounding. What is left is a rich and fatty liquor that is pressed to remove the fat (cocoa butter) and the cacao (or “cocoa”) powder which will then be mixed with different ingredients to produce dark, milk, white and other types of chocolates. There are several health benefits and potential problems that come in these sweet chocolatey packages. <h2>The good news</h2> Cacao beans contain <a href="https://foodstruct.com/food/cocoa-bean">minerals</a> like iron, potassium, magnesium, zinc and phosphorus and some vitamins. They are also rich in beneficial chemicals called <a href="https://pubmed.ncbi.nlm.nih.gov/23150750/">polyphenols</a>. These are great antioxidants, with the potential to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5465250/">improve heart health</a>, increase <a href="https://pubmed.ncbi.nlm.nih.gov/25164923/">nitric oxide</a> (which dilates blood vessels) and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3488419/">reduce blood pressure</a>, provide food for gut microbiota and <a href="https://www.mdpi.com/2072-6643/12/7/1908">promote gut health</a>, boost the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5465250/">immune system</a> and reduce inflammation. However, the concentration of polyphenols in the chocolate we eat depends largely on the cocoa solid amounts used in the final product. In general terms, the darker the chocolate, the more cocoa solids, minerals and polyphenols it has. For example, dark chocolates may have around <a href="https://www.tandfonline.com/doi/full/10.1080/10942912.2011.614984">seven times more polyphenols</a> compared to white chocolates and <a href="https://www.tandfonline.com/doi/full/10.1080/10942912.2011.614984">three times more polyphenols</a> compared to milk chocolates. <h2>But also some bad news</h2> Unfortunately, the <a href="https://theconversation.com/treat-or-treatment-chocolate-is-good-but-cocoa-is-better-for-your-heart-3084">health benefits of cocoa solids</a> are easily offset by the high sugar and fat content of modern-day chocolates. For example, milk and white chocolate eggs are on average 50% sugar, 40% fat (mostly saturated fats) – which means a lot of added kilojoules (calories). Also, there may be some side effects that come with ingesting chocolate. Cocoa beans include a compound called theobromine. While it has the anti-inflammatory properties responsible for some of the health benefits of chocolate, it is also a mild brain stimulant that acts in a similar way to caffeine. The mood boost it offers may also be partly responsible for how much we <a href="https://www.frontiersin.org/articles/10.3389/fphar.2015.00030/full?crsi=662496658&cicada_org_src=healthwebmagazine.com&cicada_org_mdm=direct">like chocolate</a>. Dark chocolate has higher theobromine compared to milk and white chocolate. But accordingly, overindulging in chocolate (and therefore theobromine) may lead to feeling restless, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3672386/">headaches</a> and nausea. <h2>What else is in your chocolate?</h2> Milk and dairy-based chocolates may also cause stomach upset, abdominal pain and bloating in people with <a href="https://dietitiansaustralia.org.au/health-advice/lactose-intolerance">lactose intolerance</a>. This happens when we don’t produce enough lactase enzymes to digest milk sugar (lactose). People with lactose intolerance can usually tolerate up to 6 grams of lactose without showing symptoms. Milk chocolate can have around <a href="https://www.ncbi.nlm.nih.gov/books/NBK310258/">3 grams of lactose</a> per 40 grams (the size of a standard chocolate bar). So two chocolate bars (or the equivalent in milk chocolate eggs or bunnies) may be enough to cause symptoms. It’s worth noting that lactase enzyme activity dramatically declines as we age, with the highest activity in newborns and children. So lactose sensitivity or intolerance may not be such an issue for your kids and your symptoms may increase over time. Genetics also plays a major role in how sensitive people are to lactose. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6815241/">Allergic reactions</a> to chocolate are usually due to the added ingredients or cross-contamination with potential allergens such as nuts, milk, soy, and some sweeteners used in the production of chocolate. Symptoms can be mild (acne, rashes and stomach pain) or more severe (swelling of the throat and tongue and shortness of breath). If you or your family members have known allergic reactions, make sure you read the label before indulging – especially in a whole block or basket of the stuff. And if you or your family members do experience symptoms of an allergic reaction after eating chocolate, <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/allergic-reactions-emergency-first-aid">seek medical attention</a> immediately. <h2>4 take home tips</h2> So, if you are like me and have a weakness for chocolate there are a few things you can do to make the experience a good one.<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/202848/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <ol> <li>keep an eye out for the darker chocolate varieties with higher cocoa solids. You may notice a percentage on labelling, which refers to how much of its weight is from cocoa beans. In general, the higher this percentage, the lower the sugar. White chocolate has almost no cocoa solid, and mostly cocoa butter, sugar and other ingredients. Dark chocolate has 50–100% cocoa beans, and less sugar. Aim for at least 70% cocoa</li> <li>read the fine print for additives and possible cross-contamination, especially if allergies might be an issue</li> <li>the ingredients list and nutrition information panel should tell you all about the chocolate you choosing. Go for varieties with lower sugar and less saturated fat. Nuts, seeds and dried fruits are better ingredients to have in your chocolate than sugar, creme, syrup, and caramel</li> <li>finally, treat yourself – but keep the amount you have within sensible limits!</li> </ol> <a href="https://theconversation.com/profiles/saman-khalesi-366871">Saman Khalesi</a>, Postdoctoral Fellow of the National Heart Foundation & Senior Lecturer and Discipline Lead in Nutrition, School of Health, Medical and Applied Sciences, <a href="https://theconversation.com/institutions/cquniversity-australia-2140">CQUniversity Australia</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
