Will watching the Olympic Games make you eat more?

<div class="theconversation-article-body"><em><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></em></p> <p>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?</p> <p>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.</p> <h2>From screens to junk food</h2> <p>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.</p> <p>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.</p> <p>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).</p> <p>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.</p> <h2>Why is this happening?</h2> <p>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.</p> <p>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.</p> <h2>So what?</h2> <p>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.</p> <p>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.</p> <p>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.<!-- Below is The Conversation's page counter tag.

No croutons, no anchovies, no bacon: the 100-year-old Mexican origins of the Caesar salad

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/garritt-c-van-dyk-1014186">Garritt C. Van Dyk</a>, <a href="https://theconversation.com/institutions/university-of-newcastle-1060"><em>University of Newcastle</em></a></em></p> <p>The most seductive culinary myths have murky origins, with a revolutionary discovery created by accident, or out of necessity.</p> <p>For the Caesar salad, these classic ingredients are spiced up with a family food feud and a spontaneous recipe invention on the Fourth of July, across the border in Mexico, during Prohibition.</p> <p>Our story is set during the era when America banned the production and sale of alcohol from <a href="https://www.atf.gov/our-history/timeline/18th-amendment-1919-national-prohibition-act">1919–1933</a>.</p> <p>Two brothers, Caesar (Cesare) and Alex (Alessandro) Cardini, moved to the United States from Italy. Caesar opened a restaurant in California in 1919. <a href="https://historicalmx.org/items/show/195">In the 1920s</a>, he opened another in the Mexican border town of Tijuana, serving food and liquor to Americans looking to circumvent Prohibition.</p> <p>Tijuana’s Main Street, packed with saloons, became a popular destination for southern Californians looking for drink. It claimed to have the “<a href="https://www.google.com/books/edition/Satan_s_Playground/znhxImXG8e0C">world’s longest bar</a>” at the Ballena, 215 feet (66 metres) long with ten bartenders and 30 waitresses.</p> <p>The story of the Caesar salad, allegedly 100 years old, is one of a cross-border national holiday Prohibition-era myth, a brotherly battle for the claim to fame and celebrity chef endorsements.</p> <h2>Necessity is the mother of invention</h2> <p><a href="https://classicsandiego.com/restaurants/caesars-restaurant-tijuana/">On July 4 1924</a>, so the story goes, Caesar Cardini was hard at work in the kitchen of his restaurant, Caesar’s Place, packed with holiday crowds from across the border looking to celebrate with food and drink.</p> <p>He was confronted with a chef’s worst nightmare: running out of ingredients in the middle of service.</p> <p>As supplies for regular menu items dwindled, Caesar decided to improvise with what he had on hand.</p> <p>He took ingredients in the pantry and cool room and combined the smaller leaves from hearts of cos lettuce with a dressing made from coddled (one-minute boiled) eggs, olive oil, black pepper, lemon juice, a little garlic and Parmesan cheese.</p> <p>The novel combination was a huge success with the customers and became a regular menu item: the Caesar salad.</p> <h2>Et tu, Alex?</h2> <p>There is another version of the origin of the famous salad, made by Caesar’s brother, Alex, at his restaurant in Tijuana.</p> <p>Alex claims Caesar’s “inspiration” was actually a menu item at his place, the “<a href="https://www.bbc.com/travel/article/20190521-the-surprising-truth-about-caesar-salad">aviator’s salad</a>”, named because he made it as a morning-after pick-me-up for American pilots after a long night drinking.</p> <p>His version had many of the same ingredients, but used lime juice, not lemon, and was served with large croutons covered with mashed anchovies.</p> <p>When Caesar’s menu item later became famous, Alex asserted his claim as the true inventor of the salad, now named for his brother.</p> <h2>Enter the celebrity chefs</h2> <p>To add to the intrigue, two celebrity chefs championed the opposing sides of this feud. <a href="https://www.google.com/books/edition/Appetite_for_Life/sEAfuK8lDjkC">Julia Child</a> backed Caesar, and <a href="https://www.google.com/books/edition/The_Essential_Cuisines_of_Mexico/gzsGAwAAQBAJ">Diana Kennedy</a> (not nearly as famous, but known for her authentic Mexican cookbooks) supported Alex’s claim.</p> <p>By entering the fray, each of these culinary heavyweights added credence to different elements of each story and made the variations more popular in the US.</p> <p>While Child reached more viewers in print and on television, Kennedy had local influence, known for promoting regional Mexican cuisine.</p> <p>While they chose different versions, the influence of major media figures contributed to the evolution of the Caesar salad beyond its origins.</p> <p>The original had no croutons and no anchovies. As the recipe was codified into an “official” version, garlic was included in the form of an infused olive oil. Newer versions either mashed anchovies directly into the dressing or added Worcestershire sauce, which has anchovies in the mix.</p> <p>Caesar’s daughter, Rosa, always maintained her father was the original inventor of the salad. She continued to market her father’s <a href="https://classicsandiego.com/restaurants/caesar-cardini-cafe/">trademarked recipe</a> after his death in 1954.</p> <p>Ultimately she won the battle for her father’s claim as the creator of the dish, but elements from Alex’s recipe have become popular inclusions that deviate from the purist version, so his influence is present – even if his contribution is less visible.</p> <h2>No forks required – but a bit of a performance</h2> <p>If this weren’t enough, there is also a tasty morsel that got lost along the way.</p> <p>Caesar salad was originally meant to be eaten as finger food, with your hands, using the baby leaves as scoops for the delicious dressing ingredients.</p> <p>For <a href="https://www.latimes.com/food/story/2024-01-30/original-caesar-salad-tijuana-100-years">presentation</a> in a restaurant, the salad was also created in front of the diners’ table, on a rolling cart, with some recommending a “true” Caesar salad was tossed only seven times, clockwise.</p> <p>This extra level of drama, performance and prescribed ritual was usually limited to alcohol-doused flaming desserts.</p> <p>To have a humble salad, invented in desperation, elevated to this kind of treatment made it a very special dish – even without any bacon.<!-- Below is The Conversation's page counter tag.

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

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/emma-beckett-22673">Emma Beckett</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>Do you struggle to eat your fruits and vegetables? You are not alone. Less than 5% of Australians eat the recommended serves of fresh produce <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/dietary-behaviour/latest-release">each day</a> (with 44% eating enough fruit but only 6% eating the recommended vegetables).</p> <p>Adults <a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups">should aim to eat</a> at least five serves of vegetables (or roughly 375 grams) and two serves of fruit (about 300 grams) each day. Fruits and vegetables help keep us healthy because they have lots of nutrients (vitamins, minerals and fibre) and health-promoting bioactive compounds (substances not technically essential but which have health benefits) without having many calories.</p> <p>So, if you are having trouble <a href="https://theconversation.com/want-your-child-to-eat-more-veggies-talk-to-them-about-eating-the-rainbow-195563">eating the rainbow</a>, you might be wondering – is it OK to drink your fruits and vegetables instead in a juice or smoothie? Like everything in nutrition, the answer is all about context.</p> <h2>It might help overcome barriers</h2> <p>Common reasons for not eating enough fruits and vegetables are <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/1747-0080.12735">preferences, habits, perishability, cost, availability, time and poor cooking skills</a>. Drinking your fruits and vegetables in juices or smoothies can help overcome some of these barriers.</p> <p><a href="https://onlinelibrary.wiley.com/doi/full/10.1111/j.1467-3010.2009.01760.x">Juicing or blending</a> can help disguise tastes you don’t like, like bitterness in vegetables. And it can blitz imperfections such as bruises or soft spots. Preparation doesn’t take much skill or time, particularly if you just have to pour store-bought juice from the bottle. Treating for food safety and shipping time does change the make up of juices slightly, but unsweetened juices still remain significant sources of <a href="https://pubmed.ncbi.nlm.nih.gov/12403253/">nutrients</a> and <a href="https://www.emerald.com/insight/content/doi/10.1108/00070701111140089/full/html?fullSc=1">beneficial bioactives</a>.</p> <p>Juicing can <a href="https://academic.oup.com/nutritionreviews/advance-article-pdf/doi/10.1093/nutrit/nuz031/30096176/nuz031.pdf">extend shelf life</a> and reduce the cost of nutrients. In fact, when researchers looked at the density of nutrients relative to the costs of common foods, <a href="https://www.mdpi.com/1660-4601/18/11/5771">fruit juice was the top performer</a>.</p> <h2>So, drinking my fruits and veggies counts as a serve, right?</h2> <p>How juice is positioned in healthy eating recommendations is a bit confusing. The <a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups/fruit">Australian Dietary Guidelines</a> include 100% fruit juice with fruit but vegetable juice isn’t mentioned. This is likely because vegetable juices weren’t as common in 2013 when the guidelines were last revised.</p> <p><a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups/fruit">The guidelines</a> also warn against having juice too often or in too high amounts. This appears to be based on the logic that juice is similar, but not quite as good as, whole fruit. Juice has lower levels of fibre compared to fruits, with fibre important for gut health, heart health and promoting feelings of fullness. Juice and smoothies also release the sugar from the fruit’s other structures, making them “free”. The <a href="https://www.who.int/publications-detail-redirect/9789241549028">World Health Organization recommends</a> we limit free sugars for good health.</p> <p>But fruit and vegetables are more than just the sum of their parts. When we take a “<a href="https://hal.science/hal-01630639/">reductionist</a>” approach to nutrition, foods and drinks are judged based on assumptions made about limited features such as sugar content or specific vitamins.</p> <p>But these features might not have the impact we logically assume because of the complexity of foods and people. When humans eat varied and complex diets, we don’t necessarily need to be concerned that some foods are lower in fibre than others. Juice can retain the nutrients and bioactive compounds of fruit and vegetables and even add more because parts of the fruit we don’t normally eat, like the skin, can be included.</p> <h2>So, it is healthy then?</h2> <p>A recent <a href="https://academic.oup.com/nutritionreviews/advance-article/doi/10.1093/nutrit/nuae036/7659479?login=false">umbrella review of meta-analyses</a> (<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8977198/">a type of research</a> that combines data from multiple studies of multiple outcomes into one paper looked at the relationship between 100% juice and a range of health outcomes.</p> <p>Most of the evidence showed juice had a neutral impact on health (meaning no impact) or a positive one. Pure 100% juice was linked to improved heart health and inflammatory markers and wasn’t clearly linked to weight gain, multiple cancer types or metabolic markers (such as blood sugar levels).</p> <p>Some health risks linked to drinking juice were <a href="https://academic.oup.com/nutritionreviews/advance-article/doi/10.1093/nutrit/nuae036/7659479?login=false">reported</a>: death from heart disease, prostate cancer and diabetes risk. But the risks were all reported in <a href="https://www.cancer.gov/research/participate/what-are-observational-studies#:%7E:text=Observational%20studies%20are%20research%20studies,over%20a%20period%20of%20time.">observational studies</a>, where researchers look at data from groups of people collected over time. These are not controlled and do not record consumption in the moment. So other drinks people think of as 100% fruit juice (such as sugar-sweetened juices or cordials) might accidentally be counted as 100% fruit juice. These types of studies are not good at showing the direct causes of illness or death.</p> <h2>What about my teeth?</h2> <p>The common belief juice damages teeth might not stack up. Studies that show juice damages teeth often <a href="https://www.frontiersin.org/articles/10.3389/fpubh.2019.00190/full">lump 100% juice in with sweetened drinks</a>. Or they use model systems like fake mouths that <a href="https://www.frontiersin.org/articles/10.3389/fpubh.2019.00190/full">don’t match</a> how people drinks juice in real life. Some <a href="https://www.frontiersin.org/journals/public-health/articles/10.3389/fpubh.2019.00190/full">use extreme scenarios</a> like sipping on large volumes of drink frequently over long periods of time.</p> <p>Juice is acidic and does contain sugars, but it is possible proper oral hygiene, including <a href="https://www.sciencedirect.com/science/article/abs/pii/S0300571207000152?via%3Dihub">rinsing, cleaning</a> and using straws can mitigate these risks.</p> <p>Again, reducing juice to its acid level misses the rest of the story, including the nutrients and bioactives contained in juice that are <a href="https://www.sciencedirect.com/science/article/pii/S2352385919300210#:%7E:text=Research%20has%20also%20confirmed%20that,prevention%20of%20oral%20inflammatory%20disorders.">beneficial to oral health</a>.</p> <h2>So, what should I do?</h2> <p>Comparing whole fruit (a food) to juice (a drink) can be problematic. They serve different culinary purposes, so aren’t really interchangeable.</p> <p>The Australian Guide to Healthy Eating recommends <a href="https://www.eatforhealth.gov.au/guidelines/australian-guide-healthy-eating">water as the preferred beverage</a> but this assumes you are getting all your essential nutrients from eating.</p> <p>Where juice fits in your diet depends on what you are eating and what other drinks it is replacing. Juice might replace water in the context of a “perfect” diet. Or juice might replace <a href="https://www.cambridge.org/core/journals/public-health-nutrition/article/substitution-of-pure-fruit-juice-for-fruit-and-sugarsweetened-beverages-and-cardiometabolic-risk-in-epicnl-a-prospective-cohort-study/B7314F1198109712DE0F2E44D919A6A7">alcohol or sugary soft drinks</a> and make the relative benefits look very different.</p> <h2>On balance</h2> <p>Whether you want to eat your fruits and vegetables or drink them comes down to what works for you, how it fits into the context of your diet and your life.</p> <p>Smoothies and juices aren’t a silver bullet, and there is no evidence they work as a “cleanse” or <a href="https://theconversation.com/lemon-water-wont-detox-or-energise-you-but-it-may-affect-your-body-in-other-ways-180035">detox</a>. But, with society’s low levels of fruit and vegetable eating, having the option to access nutrients and bioactives in a cheap, easy and tasty way shouldn’t be discouraged either.<!-- Below is The Conversation's page counter tag.

Former Home and Away star admits brutal attack on woman

<p>A former <em>Home and Away</em> star has admitted to bashing a woman during a suspected mental health crisis.</p> <p>Orpheus Pledger, 31, faced Melbourne Magistrates’ Court on Monday via a video link from custody at Ravenhall Correctional Centre. </p> <p>Police prosecutor Fionnuala Kennedy said Pledger attacked the victim repeatedly over a three-month period at a home in Northcote, Melbourne, with one of the attacks captured on a motion-capture camera on March 25. </p> <p>Footage from the camera showed Pledger grabbing the woman's hair, pulling her to the ground and stomping on her head. </p> <p>The court was told that the woman called triple zero at 1.35am to raise concerns Pledger was suffering a “mental health episode", before the line disconnected right after she said “he’s coming.” </p> <p>Officers arrived 15 minutes later and found the woman lying on the floor of her home unable to get up, with Pledger nowhere to be seen.</p> <p>The woman was taken to hospital, where doctors noted that she had bruising on her forehead, a laceration to her cheek, bruising to her right hand and marks on her face and ear.</p> <p>The court was told that he was arrested the following day, but he was unable to be interviewed because of his "erratic behaviour". </p> <p>He was released in April for a court-ordered medical assessment due to concerns for his mental health, but he fled from the hospital on April 23 after a six hour wait. </p> <p>He then returned to the woman's home to collect his things and when asked to leave, he told her: “why, I haven’t done anything”. </p> <p>Police issued a public appeal before he was arrested two days later. </p> <p>Defence lawyer Jasper MacCuspie noted that during that time, his client was unable to get the mental health assessment he required, due to limited resources, saying that it was a widespread issue within the health system.</p> <p>The court heard that there is currently a shortage of ambulance and police resources, which Magistrate Justin Foster labelled as “outrageous”.</p> <p>““The only reason I bailed him at the time was because there was nothing available for him to be  … assessed in a prison setting. And there is no money in the hospital to have these important things assessed,” he said. </p> <p>“There’s a shortage of everything at the moment, it’s outrageous.”</p> <p>MacCuspie also said that his client had begun acting at the age of eight or nine but fell into the wrong crowd, and his drug use escalated in his late 20s when he was declined a role on US TV series <em>The 100</em>. </p> <p>“At the very last minute that fell through. It was a destabilising event,” MacCuspie said.</p> <p>“He aspires towards acting in future, but accepts by virtue of matter that’s a somewhat challenging prospect,” he added. </p> <p>Pledger will be assessed for a community corrections order, but has pleaded guilty to four assault-related charges, and will be sentenced on Wednesday. </p> <p><em>Images: news.com.au/ Channel Seven</em></p>

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

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/daniel-eldridge-1494633">Daniel Eldridge</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>Spicy foods taste spicy because they contain a family of compounds called capsaicinoids. Capsaicin is the major culprit. It’s found in chillies, jalapeños, cayenne pepper, and is even the active ingredient in <a href="https://pubmed.ncbi.nlm.nih.gov/31334983/">pepper spray</a>.</p> <p>Capsaicin doesn’t actually physically heat up your mouth. The burning sensation comes from receptors in the mouth reacting to capsaicin and sending a signal to the brain that something is very hot.</p> <p>That’s why the “hot” chilli sensation feels so real – we even respond by sweating. To alleviate the heat, you need to remove the capsaicin from your mouth.</p> <p>So why doesn’t drinking water help make that spicy feeling go away? And what would work better instead?</p> <h2>Water-loving and water-hating molecules</h2> <p>To help us choose what might wash the capsaicin away most effectively, it’s helpful to know that capsaicin is a hydrophobic molecule. That means it hates being in contact with water and will not easily mix with it.</p> <p>Look what happens when you try to mix hydrophobic sand with water.</p> <figure><iframe src="https://www.youtube.com/embed/H8cj9CpHW7w?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>On the other hand, hydrophilic molecules love water and are very happy to mix with it.</p> <p>You’ve likely seen this before. You can easily dissolve hydrophilic sugar in water, but it’s hard to wash away hydrophobic oils from your pan using tap water alone.</p> <p>If you try to wash hydrophobic capsaicin away with water, it won’t be very effective, because hydrophilic and hydrophobic substances don’t mix.</p> <p>Going for iced water will be even less effective, as hydrophobic capsaicin is even less soluble in water at lower temperatures. You may get a temporary sense of relief while the cold liquid is in your mouth, but as soon as you swallow it, you’ll be back where you started.</p> <p>Instead, a good choice would be to consume something that is also hydrophobic. This is because of an old-but-true adage in chemistry that “like dissolves like”.</p> <p>The idea is that generally, hydrophobic substances will not dissolve in something hydrophilic – like water – but will dissolve in something that is also hydrophobic, as this video shows:</p> <figure><iframe src="https://www.youtube.com/embed/s5yfs-Pr_y8?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>My mouth is on fire. What should I drink instead of water?</h2> <p>A swig of oil would likely be effective, but is perhaps not so palatable.</p> <p>Milk makes for an ideal choice for two reasons.</p> <p>The first is that milk contains hydrophobic fats, which the capsaicin will more easily dissolve in, allowing it to be washed away.</p> <p>The second is that dairy products contain a protein called casein. Casein is an emulsifier, a substance that helps oils and water mix, as in this video:</p> <figure><iframe src="https://www.youtube.com/embed/S4XeQhZRLDE?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Casein plays a large role in keeping the fat mixed throughout your glass of milk, and it also has a strong affinity for capsaicin. It will readily wrap up and encapsulate capsaicin molecules and assist in carrying them away from the receptor. This relieves the <a href="https://pubmed.ncbi.nlm.nih.gov/36510373/">burning sensation</a>.</p> <h2>OK but I hate drinking milk. What else can I try?</h2> <p>What about raita? This dish, commonly served with Indian curries, is made primarily from yoghurt. So aside from being its own culinary experience, raita is rich in fats, and therefore contains plenty of hydrophobic material. It also contains casein, which will again help lock up and remove the capsaicin.</p> <p>Ice cream would also work, as it contains both casein and large amounts of hydrophobic substances.</p> <p>Some studies have also shown that consuming <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9328490/">drinks with large amounts of sugar</a> can relieve spiciness.</p> <p>What about reaching for that ice cold beer?</p> <p>This is commonly suggested as a suitable approach to stop the burning. At first glance, this may seem a good idea because capsaicin is highly soluble in alcohol.</p> <p>However, most beers only contain between 4–6% alcohol. The bulk of the liquid in beer is water, which is hydrophilic and cannot wash away capsaicin. The small amount of alcohol in your beer would make it slightly more effective, but not to any great degree.</p> <p>Your curry and beer may taste great together, but that’s likely the only benefit.</p> <p>In truth, an alcoholic beverage is not going to help much unless you go for something with a much, much higher alcohol content, which comes with its own problems.<!-- Below is The Conversation's page counter tag.

"Love harder": Perth brothers farewelled at emotional memorial service

<p>Six weeks after they were <a href="https://www.oversixty.com.au/health/caring/tragic-new-details-emerge-over-aussie-brothers-missing-in-mexico" target="_blank" rel="noopener">shot dead</a> while on a surfing trip to Mexico, Perth brothers Jake and Callum Robinson have been farewelled in a heart-wrenching private memorial on Saturday. </p> <p>The memorial took place in Perth’s Sacred Heart College, where the brothers attended high school, and hundreds gathered at the college to remember the brothers. </p> <p>It was also live-streamed for those who could not fit into the theatre at the college, with Callum's friends also watching on from America, where he spent the last 14 years of his life. </p> <p>In an emotional tribute, their parents, Debra and Martin Robinson,  thanked loved ones abroad and in Australia for their endless support, and talked about how special their sons were. </p> <p>"We're not here to dwell on the where or the how or try to understand the why of their passing but instead to say goodbye to two young men and hopefully start the healing process for everyone," Mr Robinson said. </p> <p>“It’s hard to describe the feeling of when your adult children come and visit you, until it’s gone,” Mrs Robinson added.</p> <p>“They loved life and they followed their dreams.</p> <p>“They were intelligent, respectful men with so much more to offer the world.”</p> <p>The cover of a memorial brochure had the phrase: “LIVE BIGGER, SHINE BRIGHTER, LOVE HARDER”. </p> <p>With shaky voices, the grieving parents described how their two sons exuded “pure love”. </p> <p>"We loved that Jake was curious, kind and happy and never judgemental. Callum always made a conscious decision to wake up and be positive every day. He saw so much fun in life," Mrs Robinson said. </p> <p>"We look around the room today at everyone and it gives us strength, so thank you.</p> <p>"We have cried many tears and we will cry many more … We miss you beyond description, Callum and Jakie boy, please shine on us."</p> <p>Childhood friends Adam Moore and Simon Moore also shared anecdotes about their friendships with the brothers. </p> <p>Adam recalled how the two brothers always excelled "at any sport imaginable" and always had so much energy, and Simon spoke of their surfing adventures through the years. </p> <p>The brothers and their American friend Jack Carter Rhoad were last seen alive on April 27. They were allegedly robbed for their car tyres and murdered while they were camping in the Baja California coastline. </p> <p>Three people have been <a href="https://www.oversixty.com.au/health/caring/arrests-made-over-aussie-surfers-missing-in-mexico" target="_blank" rel="noopener">arrested</a> over their suspected involvement in the robbery. </p> <p><em>Image: 7News</em></p>

With all this bird flu around, how safe are eggs, chicken or milk?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/enzo-palombo-249510">Enzo Palombo</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>Recent outbreaks of bird flu – in <a href="https://www.cdc.gov/flu/avianflu/avian-flu-summary.htm">US dairy herds</a>, <a href="https://www.abc.net.au/news/rural/2024-06-04/third-victorian-poultry-farm-declares-outbreak-avian-influenza/103932694">poultry farms in Australia</a> and elsewhere, and <a href="https://theconversation.com/bird-flu-is-hitting-australian-poultry-farms-and-the-first-human-case-has-been-reported-in-victoria-heres-what-we-know-230691">isolated cases</a> <a href="https://www.statnews.com/2024/05/30/bird-flu-third-case-human-infection-caused-respiratory-symptoms/">in humans</a> – have raised the issue of food safety.</p> <p>So can the virus transfer from infected farm animals to contaminate milk, meat or eggs? How likely is this?</p> <p>And what do we need to think about to minimise our risk when shopping for or preparing food?</p> <h2>How safe is milk?</h2> <p>Bird flu (or avian influenza) is a bird disease caused by specific types of influenza virus. But the virus can also infect cows. <a href="https://www.cdc.gov/flu/avianflu/avian-flu-summary.htm">In the US</a>, for instance, to date more than 80 dairy herds in at least nine states have been infected with the H5N1 version of the virus.</p> <p>Investigations are <a href="https://www.aphis.usda.gov/livestock-poultry-disease/avian/avian-influenza/hpai-detections/livestock">under way</a> to confirm how this happened. But we do know infected birds can shed the virus in their saliva, nasal secretions and faeces. So bird flu can potentially contaminate animal-derived food products during processing and manufacturing.</p> <p>Indeed, fragments of bird flu genetic material (RNA) were found in <a href="https://theconversation.com/how-bird-flu-virus-fragments-get-into-milk-sold-in-stores-and-what-the-spread-of-h5n1-in-cows-means-for-the-dairy-industry-and-milk-drinkers-228689">cow’s milk</a> from the dairy herds associated with <a href="https://www.statnews.com/2024/05/30/bird-flu-third-case-human-infection-caused-respiratory-symptoms/">infected US farmers</a>.</p> <p>However, the spread of bird flu among cattle, and possibly to humans, is likely to have been caused through contact with <a href="https://www.agriculturedive.com/news/contaminated-milk-equipment-potential-source-of-bird-flu-spread-to-cattle/712555/">contaminated milking equipment</a>, not the milk itself.</p> <p>The test used to detect the virus in milk – which uses similar PCR technology to lab-based COVID tests – is also highly sensitive. This means it can detect very low levels of the bird flu RNA. But the test does not distinguish between live or inactivated virus, just that the RNA is present. So from this test alone, we cannot tell if the virus found in milk is infectious (and capable of infecting humans).</p> <p>Does that mean milk is safe to drink and won’t transmit bird flu? Yes and no.</p> <p>In Australia, where bird flu has not been reported in dairy cattle, the answer is yes. It is safe to drink milk and milk products made from Australian milk.</p> <p>In the US, the answer depends on whether the milk is <a href="https://www.sciencedirect.com/science/article/abs/pii/B978184569216250013X?via%3Dihub">pasteurised</a>. We know pasteurisation is a common and reliable method of destroying concerning microbes, including influenza virus. Like most viruses, influenza virus (including bird flu virus) is inactivated by heat.</p> <p>Although there is little direct research on whether pasteurisation inactivates H5N1 in milk, we can extrapolate from what we know about heat inactivation of H5N1 in <a href="https://www.sciencedirect.com/science/article/pii/S0362028X22060732?via%3Dihub">chicken</a> and <a href="https://www.mdpi.com/2036-7481/13/4/60">eggs</a>.</p> <p>So we can be confident there is no risk of bird flu transmission via pasteurised milk or milk products.</p> <p>However, it’s another matter for unpasteurised or “raw” US milk or milk products. A recent <a href="https://www.nejm.org/doi/full/10.1056/NEJMc2405495">study</a> showed mice fed raw milk contaminated with bird flu developed signs of illness. So to be on the safe side, it would be advisable to avoid raw milk products.</p> <h2>How about chicken?</h2> <p>Bird flu has caused sporadic outbreaks in wild birds and domestic poultry worldwide, including <a href="https://theconversation.com/bird-flu-is-hitting-australian-poultry-farms-and-the-first-human-case-has-been-reported-in-victoria-heres-what-we-know-230691">in Australia</a>. In recent weeks, there have been <a href="https://www.abc.net.au/news/rural/2024-06-04/third-victorian-poultry-farm-declares-outbreak-avian-influenza/103932694">three reported outbreaks</a> in <a href="https://agriculture.vic.gov.au/biosecurity/animal-diseases/poultry-diseases/avian-influenza-bird-flu#h2-0">Victorian poultry farms</a> (two with H7N3 bird flu, one with H7N9). There has been <a href="https://www.abc.net.au/news/rural/2024-05-23/bird-flu-detected-western-australia-chicken-farm/103880002">one</a> reported outbreak in <a href="https://www.agric.wa.gov.au/livestock-biosecurity/avian-influenza">Western Australia</a> (H9N2).</p> <p>The strains of bird flu identified in the Victorian and Western Australia outbreaks can cause human infection, although these <a href="https://agriculture.vic.gov.au/biosecurity/animal-diseases/poultry-diseases/avian-influenza-bird-flu#h2-8">are rare</a> and typically result from close contact with infected live birds or <a href="https://www.who.int/emergencies/situations/avian-influenza-a-(h7n9)-virus-outbreak">contaminated environments</a>.</p> <p>Therefore, the chance of bird flu transmission in chicken meat is remote.</p> <p>Nonetheless, it is timely to remind people to handle chicken meat with caution as many dangerous pathogens, such as <em>Salmonella</em> and <em>Campylobacter</em>, can be found on chicken carcasses.</p> <p>Always handle chicken meat carefully when shopping, transporting it home and storing it in the kitchen. For instance, make sure no meat juices cross-contaminate other items, consider using a cool bag when transporting meat, and refrigerate or freeze the meat within two hours.</p> <p><a href="https://theconversation.com/no-you-shouldnt-wash-raw-chicken-before-cooking-it-so-why-do-people-still-do-it-192723">Avoid washing your chicken</a> before cooking to prevent the spread of disease-causing microbes around the kitchen.</p> <p>Finally, cook chicken thoroughly as viruses (including bird flu) <a href="https://www.sciencedirect.com/science/article/pii/S0362028X22060732?via%3Dihub">cannot survive</a> cooking temperatures.</p> <h2>Are eggs safe?</h2> <p>The recent Australian outbreaks have occurred in egg-laying or mixed poultry flocks, so concerns have been raised about bird flu transmission via contaminated chicken eggs.</p> <p>Can flu viruses contaminate chicken eggs and potentially spread bird flu? It appears so. A <a href="https://www.sciencedirect.com/science/article/pii/S0196655306011862?via%3Dihub">report</a> from 2007 said it was feasible for influenza viruses to enter through the eggshell. This is because influenza virus particles are smaller (100 nanometres) than the pores in eggshells (at least 200 nm).</p> <p>So viruses could enter eggs and be protected from cleaning procedures designed to remove microbes from the egg surface.</p> <p>Therefore, like the advice about milk and meat, cooking eggs is best.</p> <p>The <a href="https://www.fda.gov/food/egg-guidance-regulation-and-other-information/questions-and-answers-regarding-safety-eggs-during-highly-pathogenic-avian-influenza-outbreaks">US Food and Drug Administration</a> recommends cooking poultry, eggs and other animal products to the proper temperature and preventing cross-contamination between raw and cooked food.</p> <h2>In a nutshell</h2> <p>If you consume pasteurised milk products and thoroughly cook your chicken and eggs, there is nothing to worry about as bird flu is inactivated by heat.</p> <p>The real fear is that the virus will evolve into highly pathogenic versions that can be transmitted from <a href="https://theconversation.com/bird-flu-is-hitting-australian-poultry-farms-and-the-first-human-case-has-been-reported-in-victoria-heres-what-we-know-230691">human to human</a>.</p> <p>That scenario is much more frightening than any potential spread though food.<!-- Below is The Conversation's page counter tag.

"No fan of mine": Kyle Sandilands shocked on air by brutal John Blackman audio

<p>Kyle Sandilands was paying tribute to his “childhood hero” <em>Hey Hey it's Saturday </em>star John Blackman on-air Thursday morning, when he was interrupted by an audio of the late star trashing him in a recent interview. </p> <p>Speaking on the Kyle and Jackie O Show, the shock jock said he was upset when he learned of <a href="https://www.oversixty.com.au/health/caring/australia-is-a-sadder-place-shock-as-john-blackman-s-death-confirmed" target="_blank" rel="noopener">Blackman's passing</a>, but before he was able to elaborate on how the radio star was his childhood hero, his manager Bruno Bouchet interjected and told him about Blackman's brutal review. </p> <p>In a May interview on the <em>You Cannot Be Serious</em> podcast, Blackman said: “Why are we giving these two publicity hungry, oxygen thieves, waste of oxygen. The man [Sandilands] is a no talent. He doesn’t have a voice for radio, by the way.”</p> <p>Footage of Sandilands listening to the audio for the first time was shared by <em>KIIS FM</em> on their Instagram stories, and both he and Henderson were shocked. </p> <p>“I’m very confused,” Sandilands said, before coming to the conclusion that  Blackman wasn’t a fan of him because he’s not as polished as “old school” media veterans.</p> <p>“What’s happened here is old school media, TV, radio, newspapers. They’re all fake,” he said.</p> <p>“They pretend everything’s wonderful. You never really know the real person." </p> <p>He then elaborated and said that he and Henderson try to keep it real with their listeners. </p> <p>“We don’t pretend it’s a wonderful day. Even though it’s p*ssing with rain and snowing or whatever. We don’t pretend. We say, ‘Oh, what a s**t day.’ We’re just a different breed.</p> <p>“Oh well, that’s one hero of mine that’s dead. No fan of mine.”</p> <p><em>Images: Instagram</em></p>

How do I keep my fruit, veggies and herbs fresh longer? Are there any ‘hacks’?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/senaka-ranadheera-199225">Senaka Ranadheera</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p>We all know <a href="https://theconversation.com/frozen-canned-or-fermented-when-you-cant-shop-often-for-fresh-vegetables-what-are-the-best-alternatives-131678">fresh produce is good for us</a>, but fruit, vegetables and herbs have a tendency to perish quickly if left uneaten.</p> <p>This is because <a href="https://www.sciencedirect.com/science/article/abs/pii/S2212429219305188">even after harvesting</a>, produce from living plants tends to continue its biological processes. This includes respiration: producing energy from stored carbohydrates, proteins and fats while releasing carbon dioxide and water vapour. (Ever found a sprouting potato in your pantry?)</p> <p>On top of that, fresh produce also <a href="https://www.mdpi.com/journal/agriculture/special_issues/quality_safety_fresh_produce">spoils easily thanks to various microbes</a> – both harmless and ones that can cause disease, called pathogens.</p> <p>Simply chucking things in the fridge won’t solve the problem, as different types of plants will react differently to how they’re stored. So, how can you combat food waste and keep produce fresh for longer? Fortunately, there are some helpful tips.</p> <h2>Freshness and quality begin at the farm</h2> <p>Farmers always aim to harvest produce when it’s at an optimal condition, but both pre-harvest and post-harvest factors will affect freshness and quality even before you buy it.</p> <p>Pre-harvest factors are agricultural, such as climatic conditions, soil type and water availability. <a href="https://www.sciencedirect.com/science/article/abs/pii/S2212429219305188">Post-harvest factors</a> include washing and cleaning after harvesting, transportation and distribution, processing and packaging, and storage.</p> <p>As consumers we can’t directly control these factors – sometimes the veggies we buy just won’t be as good. But we can look out for things that will affect the produce once we bring it home.</p> <p>One major thing to look out for is bruised, wounded or damaged produce. This can happen at any stage of post-harvest handling, and can really speed up the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0308814609001411">decay of your veggies and fruit</a>.</p> <p>Moisture loss through damaged skin speeds up deterioration and nutrient loss. The damage also makes it easier for <a href="https://www.sciencedirect.com/science/article/pii/S2468014119301943">spoilage microbes</a> to get in.</p> <h2>To wash or not to wash?</h2> <p>You don’t need to wash your produce before storing it. A lot of what we buy has already been washed commercially. In fact, if you wash your produce and can’t get it completely dry, the added moisture could speed up decay in the fridge.</p> <p>But washing produce <a href="https://theconversation.com/do-we-really-have-to-wash-fruit-and-vegetables-53039">just before you use it</a> is important to remove dirt and pathogenic bugs.</p> <p>Don’t use vinegar in your washing water despite what you see on social media. Studies indicate <a href="https://pubmed.ncbi.nlm.nih.gov/16496573/">vinegar has no effect</a> on lowering microbial loads on fresh produce.</p> <p>Similarly, don’t use baking soda. Even though there’s some evidence baking soda <a href="https://pubs.acs.org/doi/10.1021/acs.jafc.7b03118">can remove pesticide residues</a> from the surface of some produce, it’s not advisable at home. Just use plain tap water.</p> <h2>Location, location, location</h2> <p>The main thing you need is the correct type of packaging and the correct location – you want to manage moisture loss, decay and ripening.</p> <p>The three main storage options are on the counter, in the fridge, or in a “cool, dry and dark place”, such as the pantry. Here are some common examples of produce and where best to put them.</p> <p>Bananas, onion, garlic, potatoes, sweet potato and whole pumpkin will do better in a dark pantry or cupboard. Don’t store potatoes and onions together: onions produce a gas called ethylene that makes potatoes spoil quicker, while the high moisture in potatoes spoils onions.</p> <p>In fact, don’t store fruits such as apples, pears, avocado and bananas together, because these fruits <a href="https://www.tandfonline.com/doi/full/10.1080/15538362.2013.748378#:%7E:text=%27Malindi%27%20had%20higher%20respiration%20rates,retention%20in%20fruit%20during%20ripening">release ethylene gas</a> as they ripen, making nearby fruits ripen (and potentially spoil) much faster. That is, unless you <em>do</em> want to ripen your fruits fast.</p> <p>All leafy greens, carrots, cucumbers, cauliflower and broccoli will do best in the low-humidity drawer (crisper) in the fridge. You can put them in perforated plastic bags to retain moisture but maintain air flow. But don’t put them in completely sealed bags because this can slow down ripening while <a href="https://ucanr.edu/sites/hdnmastergardeners/files/338860.pdf">trapping carbon dioxide</a>, leading to decay and bad smells.</p> <p>Some fruits will also do best in the fridge. For example, apples and citrus fruits such as oranges can keep fresh longer in the fridge (crisper drawer), although they can stay at room temperature for short periods. However, don’t store watermelon in the fridge for too long, as it will lose its flavour and deep red colour if kept refrigerated <a href="https://ucanr.edu/sites/hdnmastergardeners/files/338860.pdf">for longer than three days</a>.</p> <p>Most herbs and some leafy vegetables – like celery, spring onions and asparagus – can be kept with stems in water to keep them crisp. Keep them in a well-ventilated area and away from direct sunlight, so they don’t get too warm and wilt.</p> <figure><iframe src="https://www.youtube.com/embed/cHu10C1DAds?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">Experimenting at home is a good way to find the best ways to store your produce.</span></figcaption></figure> <h2>Fight food waste and experiment</h2> <p><strong>Don’t buy too much.</strong> Whenever possible, buy only small amounts so that you don’t need to worry about keeping them fresh. Never buy bruised, wounded or damaged produce if you plan to keep it around for more than a day.</p> <p><strong>“Process” your veggies for storage.</strong> If you do buy a large quantity – maybe a bulk option was on sale – consider turning the produce into something you can keep for longer. For example, banana puree made from really ripe bananas can be <a href="https://www.sciencedirect.com/science/article/abs/pii/S0023643817300853">stored for up to 14 days at 4°C</a>. You can use <a href="https://theconversation.com/frozen-canned-or-fermented-when-you-cant-shop-often-for-fresh-vegetables-what-are-the-best-alternatives-131678">freezing, blanching, fermentation and canning</a> for most vegetables.</p> <p><strong>Consider vacuum sealing.</strong> Vacuum packaging of vegetables and berries can keep them fresh longer, as well. For example, vacuum-sealed beans can keep up to 16 months in the fridge, but will last only about <a href="https://www.vacpac.com.au/vacuum-sealed-life-expectancy-how-long-will-my-vacuum-sealed-products-last">four weeks in the fridge unsealed</a>.</p> <p><strong>Keep track.</strong> Arrange your fridge so you can see the produce easily and use it all before it loses freshness.</p> <p><strong>Experiment with storage hacks.</strong> Social media is full of tips and hacks on how best to store produce.

What’s the difference between vegan and vegetarian?

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/katherine-livingstone-324808">Katherine Livingstone</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p>Vegan and vegetarian diets are <a href="https://link.springer.com/article/10.1007/s00394-023-03086-z">plant-based diets</a>. Both include plant foods, such as fruits, vegetables, legumes and whole grains.</p> <p>But there are important differences, and knowing what you can and can’t eat when it comes to a vegan and vegetarian diet can be confusing.</p> <p>So, what’s the main difference?</p> <h2>What’s a vegan diet?</h2> <p>A <a href="https://link.springer.com/article/10.1007/s00394-023-03086-z">vegan diet</a> is an entirely plant-based diet. It doesn’t include any meat and animal products. So, no meat, poultry, fish, seafood, eggs, dairy or honey.</p> <h2>What’s a vegetarian diet?</h2> <p>A <a href="https://link.springer.com/article/10.1007/s00394-023-03086-z">vegetarian diet</a> is a plant-based diet that generally excludes meat, poultry, fish and seafood, but can include animal products. So, unlike a vegan diet, a vegetarian diet can include eggs, dairy and honey.</p> <p>But you may be wondering why you’ve heard of vegetarians who eat fish, vegetarians who don’t eat eggs, vegetarians who don’t eat dairy, and even vegetarians who eat some meat. Well, it’s because there are variations on a vegetarian diet:</p> <ul> <li> <p>a <strong>lacto-ovo vegetarian</strong> diet excludes meat, poultry, fish and seafood, but includes eggs, dairy and honey</p> </li> <li> <p>an <strong>ovo-vegetarian</strong> diet excludes meat, poultry, fish, seafood and dairy, but includes eggs and honey</p> </li> <li> <p>a <strong>lacto-vegetarian</strong> diet excludes meat, poultry, fish, seafood and eggs, but includes dairy and honey</p> </li> <li> <p>a <strong>pescatarian</strong> diet excludes meat and poultry, but includes eggs, dairy, honey, fish and seafood</p> </li> <li> <p>a <strong>flexitarian</strong>, or semi-vegetarian diet, includes eggs, dairy and honey and may include small amounts of meat, poultry, fish and seafood.</p> </li> </ul> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/594474/original/file-20240516-16-wjg71m.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/594474/original/file-20240516-16-wjg71m.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/594474/original/file-20240516-16-wjg71m.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=456&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/594474/original/file-20240516-16-wjg71m.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=456&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/594474/original/file-20240516-16-wjg71m.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=456&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/594474/original/file-20240516-16-wjg71m.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=573&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/594474/original/file-20240516-16-wjg71m.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=573&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/594474/original/file-20240516-16-wjg71m.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=573&amp;fit=crop&amp;dpr=3 2262w" alt="" /></a><figcaption></figcaption></figure> <h2>Are these diets healthy?</h2> <p>A <a href="https://academic.oup.com/eurheartj/article/44/36/3423/7224412">2023 review</a> looked at the health effects of vegetarian and vegan diets from two types of study.</p> <p>Observational studies followed people over the years to see how their diets were linked to their health. In these studies, eating a vegetarian diet was associated with a lower risk of developing cardiovascular disease (such as heart disease or a stroke), diabetes, hypertension (high blood pressure), dementia and cancer.</p> <p>For example, in a <a href="https://www.sciencedirect.com/science/article/pii/S0002916523054497?via%3Dihub">study</a> of 44,561 participants, the risk of heart disease was 32% lower in vegetarians than non-vegetarians after an average follow-up of nearly 12 years.</p> <p>Further evidence came from randomised controlled trials. These instruct study participants to eat a specific diet for a specific period of time and monitor their health throughout. These studies showed eating a vegetarian or vegan diet led to reductions in weight, blood pressure, and levels of unhealthy cholesterol.</p> <p>For example, one <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/1832195">analysis</a> combined data from seven randomised controlled trials. This so-called meta-analysis included data from 311 participants. It showed eating a vegetarian diet was associated with a systolic blood pressure (the first number in your blood pressure reading) an average 5 mmHg lower compared with non-vegetarian diets.</p> <p>It seems vegetarian diets are more likely to be healthier, across a number of measures.</p> <p>For example, a 2022 <a href="https://link.springer.com/article/10.1007/s00394-022-02942-8">meta-analysis</a> combined the results of several observational studies. It concluded a vegetarian diet, rather than vegan diet, was recommended to prevent heart disease.</p> <p>There is also <a href="https://link.springer.com/article/10.1007/s13668-024-00533-z">evidence</a> vegans are more likely to have bone fractures than vegetarians. This could be partly due to a lower body-mass index and a lower intake of nutrients such as calcium, vitamin D and protein.</p> <h2>But it can be about more than just food</h2> <p>Many vegans, where possible, do not use products that directly or indirectly involve using animals.</p> <p>So vegans would not wear leather, wool or silk clothing, for example. And they would not use soaps or candles made from beeswax, or use products tested on animals.</p> <p>The motivation for following a vegan or vegetarian diet can vary from person to person. Common motivations <a href="https://www.sciencedirect.com/science/article/pii/S2475299123157957">include</a> health, environmental, ethical, religious or economic reasons.</p> <p>And for many people who follow a vegan or vegetarian diet, this forms a central part of their <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9231820/">identity</a>.</p> <h2>So, should I adopt a vegan or vegetarian diet?</h2> <p>If you are thinking about a vegan or vegetarian diet, here are some things to consider:</p> <ul> <li> <p>eating more plant foods does not automatically mean you are eating a healthier diet. Hot chips, biscuits and soft drinks can all be vegan or vegetarian foods. And many <a href="https://theconversation.com/we-looked-at-700-plant-based-foods-to-see-how-healthy-they-really-are-heres-what-we-found-222991">plant-based alternatives</a>, such as plant-based sausages, can be high in added salt</p> </li> <li> <p>meeting the <a href="https://www.eatforhealth.gov.au/nutrient-reference-values/nutrients">nutrient intake targets</a> for vitamin B12, iron, calcium, and iodine requires more careful planning while on a vegan or vegetarian diet. This is because meat, seafood and animal products are good sources of these vitamins and minerals</p> </li> <li> <p>eating a plant-based diet doesn’t necessarily mean <a href="https://theconversation.com/why-you-should-eat-a-plant-based-diet-but-that-doesnt-mean-being-a-vegetarian-78470">excluding</a> all meat and animal products. A healthy flexitarian diet prioritises eating more whole plant-foods, such as vegetables and beans, and less processed meat, such as bacon and sausages</p> </li> <li> <p>the <a href="https://www.eatforhealth.gov.au/guidelines/australian-dietary-guidelines-1-5">Australian Dietary Guidelines</a> recommend eating a wide variety of foods from the five food groups (fruit, vegetables, cereals, lean meat and/or their alternatives and reduced-fat dairy products and/or their alternatives). So if you are eating animal products, choose lean, reduced-fat meats and dairy products and limit processed meats.<!-- Below is The Conversation's page counter tag.

Cost of living: if you can’t afford as much fresh produce, are canned veggies or frozen fruit just as good?

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/evangeline-mantzioris-153250">Evangeline Mantzioris</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180"><em>University of South Australia</em></a></em></p> <p>The cost of living crisis is affecting how we spend our money. For many people, this means tightening the budget on the weekly supermarket shop.</p> <p>One victim may be fresh fruit and vegetables. Data from the <a href="https://www.abs.gov.au/media-centre/media-releases/australians-consuming-fewer-vegetables-fruit-and-less-milk#:%7E:text=Paul%20Atyeo%2C%20ABS%20health%20statistics,278%20to%20267%20to%20grams.%E2%80%9D">Australian Bureau of Statistics</a> (ABS) suggests Australians were consuming fewer fruit and vegetables in 2022–23 than the year before.</p> <p>The cost of living is likely compounding a problem that exists already – on the whole, Australians don’t eat enough fruit and vegetables. <a href="https://www.eatforhealth.gov.au/guidelines/australian-guide-healthy-eating">Australian dietary guidelines</a> recommend people aged nine and older should consume <a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups/fruit">two</a> serves of fruit and <a href="https://www.eatforhealth.gov.au/food-essentials/five-food-groups/vegetables-and-legumes-beans">five</a> serves of vegetables each day for optimal health. But in 2022 the <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/dietary-behaviour/latest-release">ABS reported</a> only 4% of Australians met the recommendations for both fruit and vegetable consumption.</p> <p>Fruit and vegetables are crucial for a healthy, balanced diet, providing a range of <a href="https://theconversation.com/were-told-to-eat-a-rainbow-of-fruit-and-vegetables-heres-what-each-colour-does-in-our-body-191337">vitamins</a> and minerals as well as fibre.</p> <p>If you can’t afford as much fresh produce at the moment, there are other ways to ensure you still get the benefits of these food groups. You might even be able to increase your intake of fruit and vegetables.</p> <h2>Frozen</h2> <p>Fresh produce is often touted as being the most nutritious (think of the old adage “fresh is best”). But this is not necessarily true.</p> <p>Nutrients can decline in transit from the paddock to your kitchen, and while the produce is stored in your fridge. Frozen vegetables may actually be higher in some nutrients such as <a href="https://pubmed.ncbi.nlm.nih.gov/25526594/">vitamin C and E</a> as they are snap frozen very close to the time of harvest. Variations in transport and storage can affect this slightly.</p> <p><a href="https://pubs.acs.org/doi/10.1021/jf504890k">Minerals</a> such as calcium, iron and magnesium stay at similar levels in frozen produce compared to fresh.</p> <p>Another advantage to frozen vegetables and fruit is the potential to reduce food waste, as you can use only what you need at the time.</p> <p>As well as buying frozen fruit and vegetables from the supermarket, you can freeze produce yourself at home if you have an oversupply from the garden, or when produce may be cheaper.</p> <p>A <a href="https://www.growveg.com.au/guides/freezing-vegetables-and-herbs-the-garden-foodie-version/">quick blanching</a> prior to freezing can improve the safety and quality of the produce. This is when food is briefly submerged in boiling water or steamed for a short time.</p> <p>Frozen vegetables won’t be suitable for salads but can be eaten roasted or steamed and used for soups, stews, casseroles, curries, pies and quiches. Frozen fruits can be added to breakfast dishes (with cereal or youghurt) or used in cooking for fruit pies and cakes, for example.</p> <h2>Canned</h2> <p>Canned vegetables and fruit similarly often offer a cheaper alternative to fresh produce. They’re also very convenient to have on hand. The <a href="https://nchfp.uga.edu/how/can#gsc.tab=0">canning process</a> is the preservation technique, so there’s no need to add any additional preservatives, including salt.</p> <p>Due to the cooking process, levels of heat-sensitive nutrients <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/jsfa.2825">such as vitamin C</a> will decline a little compared to fresh produce. When you’re using canned vegetables in a hot dish, you can add them later in the cooking process to reduce the amount of nutrient loss.</p> <p>To minimise waste, you can freeze the portion you don’t need.</p> <h2>Fermented</h2> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6723656/">Fermentation</a> has recently come into fashion, but it’s actually one of the oldest food processing and preservation techniques.</p> <p>Fermentation largely retains the vitamins and minerals in fresh vegetables. But fermentation may also enhance the food’s nutritional profile by creating new nutrients and allowing existing ones to be <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9352655/">absorbed more easily</a>.</p> <p>Further, fermented foods contain probiotics, which are beneficial for our <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10051273/">gut microbiome</a>.</p> <h2>5 other tips to get your fresh fix</h2> <p>Although alternatives to fresh such as canned or frozen fruit and vegetables are good substitutes, if you’re looking to get more fresh produce into your diet on a tight budget, here are some things you can do.</p> <p><strong>1. Buy in season</strong></p> <p>Based on supply and demand principles, buying local seasonal vegetables and fruit will always be cheaper than those that are imported out of season from other countries.</p> <p><strong>2. Don’t shun the ugly fruit and vegetables</strong></p> <p>Most supermarkets now sell “ugly” fruit and vegetables, that are not physically perfect in some way. This does not affect the levels of nutrients in them at all, or their taste.</p> <p><strong>3. Reduce waste</strong></p> <p>On average, an Australian household throws out <a href="https://www.ozharvest.org/food-waste-facts/">A$2,000–$2,500</a> worth of food every year. Fruit, vegetables and bagged salad are the <a href="https://www.ozharvest.org/food-waste-facts/">three of the top five foods</a> thrown out in our homes. So properly managing fresh produce could help you save money (and benefit <a href="https://endfoodwaste.com.au/why-end-food-waste/">the environment</a>).</p> <p>To minimise waste, plan your meals and shopping ahead of time. And if you don’t think you’re going to get to eat the fruit and vegetables you have before they go off, freeze them.</p> <p><strong>4. Swap and share</strong></p> <p>There are many websites and apps which offer the opportunity to swap or even pick up free fresh produce if people have more than they need. Some <a href="https://www.charlessturt.sa.gov.au/environment/sustainable-lifestyles/community-fruit-and-vege-swaps">local councils are also encouraging</a> swaps on their websites, so dig around and see what you can find in your local area.</p> <p><strong>5. Gardening</strong></p> <p>Regardless of how small your garden is you can always <a href="https://www.gardeningaustraliamag.com.au/best-vegies-grow-pots/">plant produce in pots</a>. Herbs, rocket, cherry tomatoes, chillies and strawberries all grow well. In the long run, these will offset some of your cost on fresh produce.</p> <p>Plus, when you have put the effort in to grow your own produce, <a href="https://mdpi-res.com/sustainability/sustainability-07-02695/article_deploy/sustainability-07-02695.pdf?version=1425549154">you are less likely to waste it</a>.<!-- Below is The Conversation's page counter tag.

Why a cold beer is best – chemically speaking

<p>A quiet moment in a bar has led two researchers to study how alcohol tastes at different temperatures. No, this is real science.</p> <div class="copy"> <p>“Two years ago, Xiaotao Yang and I were drinking beer together. He had just finished his doctorate degree thesis and asked me, ‘what should we do next?’” says Lei Jiang, lead author of a new study <a href="https://doi.org/10.1016/j.matt.2024.03.017" target="_blank" rel="noopener">published</a> in the materials science journal <em>Matter</em>.</p> <p>Yang and Jiang are material scientists at the Chinese Academy of Sciences.</p> <p>“At the time, I was a scientific committee member of one of the biggest Chinese alcoholic beverage companies, and I had the idea to ask the question ‘why does Chinese baijiu have a very particular concentration of alcohol, either 38%–42%, 52%–53%, or 68%–75%?’”</p> <p>Baijiu is a clear grain liquor from East Asia. It’s typically distilled from fermented sorghum (a type of grass), though it is also sometimes made from rice, wheat, barley or millet.</p> <p>“Then we decided, let’s try something, so I put a drop of beer on my hand to see the contact angle,” says Jiang.</p> <p>Contact angle is a measure of surface tension. For example, water has a low contact angle which is why it appears bead-like when placed on a surface. Solutions with high <a href="https://cosmosmagazine.com/health/body-and-mind/debunks-vices-alcohol/">alcohol</a> concentration, however, have a higher contact angle meaning they flatten and spread out.</p> <p>Contact angle also reveals how molecules within the droplet interact with each other and the surface below.</p> <p>After plotting the concentration of ethanol (alcohol) against contact angle, the scientists were surprised with what they found. There is no linear relationship between alcohol concentration and contact angle.</p> <p>Instead, increasing the amount of alcohol leads to a series of plateaus and sharp rises in the plot. Further experiments showed that this arises out of the formation of clusters of ethanol and water in the solutions.</p> <p>At low concentrations, ethanol forms pyramid-like structures around the water molecules. At high concentrations, the ethanol molecules arrange end-to-end in a chain.</p> <p>They also found that these structures change depending on temperature.</p> <p>For example, 38%–42% and 52%–53% ethanol solutions have distinct cluster structures at around room temperature, but this difference disappears at higher temperatures, like 40°C.</p> <p>“Although there is only 1% difference, the taste of baijiu at 51% and 52% is noticeably different; the taste of baijiu at 51% is similar to that of lower alcohol content, such as 38%–42%. So, in order to achieve the same taste at a lower alcohol content, the distribution of baijiu products ranges most within the 38%–42% and 52%–53% categories,” says Jiang.</p> <p>The researchers also found that there is an increase in ethanol chains at 5°C in 5% and 11% ethanol solutions – the concentration range of beer – giving it a more “ethanol-like” taste which is generally preferred.</p> <p>“At low temperature, the tetrahedral (pyramid-shaped) clusters become the low concentration amount, and this is why we drink cold beer,” says Jiang.</p> <p>The researchers say their research could help beverage companies produce the best flavour with the lowest alcohol concentration.</p> <p><em>Image credits: Shutterstock </em></p> <div> <p align="center"><noscript data-spai="1"><em><img decoding="async" fetchpriority="high" class="aligncenter size-full wp-image-198773" src="https://cdn.shortpixel.ai/spai/q_lossy+ret_img+to_auto/cosmosmagazine.com/wp-content/uploads/2023/11/Cosmos-Catch-Up-embed_728x150-1.jpg" data-spai-egr="1" alt="Sign up to our weekly newsletter" width="600" height="154" title="why a cold beer is best – chemically speaking 2"></em></noscript></p> </div> <p><em><!-- Start of tracking content syndication.

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

<p>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.</p> <p>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.</p> <p>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 <em>The Journal of Nutrition, Health, and Aging</em>. 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.</p> <h2>What daily diets revealed</h2> <p>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.</p> <p>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.</p> <h2>Vegetables that help protect cognition</h2> <p>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.”</p> <p>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.</p> <p>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.)</p> <h2>Fruit that pack a punch</h2> <p>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.</p> <p>Participants whose brains maintained performance were shown to have eaten three or more servings of vegetables and two or more servings of fruit per day. This is on par with the five servings of vegetables and two servings of fruit recommended we eat every day.</p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/healthsmart/want-to-reduce-your-dementia-risk-eat-these-4-foods-says-new-study" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

I can’t afford olive oil. What else can I use?

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/lauren-ball-14718">Lauren Ball</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/emily-burch-438717">Emily Burch</a>, <a href="https://theconversation.com/institutions/southern-cross-university-1160">Southern Cross University</a></em></p> <p>If you buy your olive oil in bulk, you’ve likely been in for a shock in recent weeks. Major supermarkets have been selling olive oil for up to A$65 for a four-litre tin, and up to $26 for a 750 millilitre bottle.</p> <p>We’ve been hearing about the health benefits of olive oil for years. And many of us are adding it to salads, or baking and frying with it.</p> <p>But during a cost-of-living crisis, these high prices can put olive oil out of reach.</p> <p>Let’s take a look at why olive oil is in demand, why it’s so expensive right now, and what to do until prices come down.</p> <h2>Remind me, why is olive oil so good for you?</h2> <p>Including olive oil in your diet can reduce your risk of developing type 2 diabetes and improve heart health through more favourable <a href="https://www.mdpi.com/2072-6643/12/6/1548">blood pressure</a>, <a href="https://www.mdpi.com/2072-6643/7/9/5356">inflammation</a> and <a href="https://www.sciencedirect.com/science/article/abs/pii/S0939475319302662">cholesterol levels</a>.</p> <p>This is largely because olive oil is high in <a href="https://www.mdpi.com/2072-6643/4/12/1989">monounsaturated fatty acids</a> and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8300823/">polyphenols</a> (antioxidants).</p> <p>Some researchers have suggested you can get these benefits from consuming up to <a href="https://www.frontiersin.org/articles/10.3389/fnut.2022.1041203/full">20 grams a day</a>. That’s equivalent to about five teaspoons of olive oil.</p> <h2>Why is olive oil so expensive right now?</h2> <p>A European heatwave and drought have <a href="https://www.abc.net.au/news/rural/2024-04-27/olive-oil-alternatives-what-you-can-use-in-cooking/103761718">limited</a> Spanish and Italian producers’ ability to supply olive oil to international markets, including Australia.</p> <p>This has been coupled with an unusually cold and short growing season for Australian <a href="https://www.abc.net.au/news/rural/2023-08-02/record-olive-oil-price-set-to-increase-again/102675452">olive oil suppliers</a>.</p> <p>The lower-than-usual production and supply of olive oil, together with heightened demand from shoppers, means prices have gone up.</p> <h2>How can I make my olive oil go further?</h2> <p>Many households buy olive oil in large quantities because it is cheaper per litre. So, if you have some still in stock, you can make it go further by:</p> <ul> <li> <p><strong>storing it correctly</strong> – make sure the lid is on tightly and it’s kept in a cool, dark place, such as a pantry or cabinet. If stored this way, olive oil can typically last <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6218649/">12–18 months</a></p> </li> <li> <p><strong>using a spray</strong> – sprays distribute oil more evenly than pourers, using less olive oil overall. You could buy a spray bottle to fill from a large tin, as needed</p> </li> <li> <p><strong>straining or freezing it</strong> – if you have leftover olive oil after frying, strain it and reuse it for other fried dishes. You could also freeze this used oil in an airtight container, then thaw and fry with it later, without affecting the oil’s <a href="https://link.springer.com/article/10.1007/s00217-022-04078-9">taste and other characteristics</a>. But for dressings, only use fresh oil.</p> </li> </ul> <h2>I’ve run out of olive oil. What else can I use?</h2> <p>Here are some healthy and cheaper alternatives to olive oil:</p> <ul> <li> <p><strong>canola oil</strong> is a good alternative for frying. It’s relatively <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/canola-oil">low</a> in saturated fat so is generally considered healthy. Like olive oil, it is high in <a href="https://pubmed.ncbi.nlm.nih.gov/23731447/">healthy monounsaturated fats</a>. Cost? Up to $6 for a 750mL bottle (home brand is about half the price)</p> </li> <li> <p><strong>sunflower oil</strong> is a great alternative to use on salads or for frying. It has a mild flavour that does not overwhelm other ingredients. Some <a href="https://www.cambridge.org/core/journals/british-journal-of-nutrition/article/conjugated-linoleic-acid-versus-higholeic-acid-sunflower-oil-effects-on-energy-metabolism-glucose-tolerance-blood-lipids-appetite-and-body-composition-in-regularly-exercising-individuals/6C035B5C6E9FD7C9D6D7F806ADA56983">studies</a> suggest using sunflower oil may help reduce your risk of heart disease by lowering LDL (bad) cholesterol and raising HDL (good) cholesterol. Cost? Up to $6.50 for a 750mL bottle (again, home brand is about half the price)</p> </li> <li> <p><strong>sesame oil</strong> has a nutty flavour. It’s good for Asian dressings, and frying. Light sesame oil is typically used as a neutral cooking oil, while the toasted type is used to flavour sauces. Sesame oil is <a href="https://onlinelibrary.wiley.com/doi/10.1002/ptr.6428">high in</a> antioxidants and has some anti-inflammatory properties. Sesame oil is generally sold in smaller bottles than canola or sunflower oil. Cost? Up to $5 for a 150mL bottle.</p> </li> </ul> <h2>How can I use less oil, generally?</h2> <p>Using less oil in your cooking could keep your meals healthy. Here are some alternatives and cooking techniques:</p> <ul> <li> <p><strong>use alternatives for baking</strong> – unless you are making an olive oil cake, if your recipe calls for a large quantity of oil, try using an alternative such as apple sauce, Greek yoghurt or mashed banana</p> </li> <li> <p><strong>use non-stick cookware</strong> – using high-quality, non-stick pots and pans reduces the need for oil when cooking, or means you don’t need oil at all</p> </li> <li> <p><strong>steam instead</strong> – steam vegetables, fish and poultry to retain nutrients and moisture without adding oil</p> </li> <li> <p><strong>bake or roast</strong> – potatoes, vegetables or chicken can be baked or roasted rather than fried. You can still achieve crispy textures without needing excessive oil</p> </li> <li> <p><strong>grill</strong> – the natural fats in meat and vegetables can help keep ingredients moist, without using oil</p> </li> <li> <p><strong>use stock</strong> – instead of sautéing vegetables in oil, try using vegetable broth or stock to add flavour</p> </li> <li> <p><strong>try vinegar or citrus</strong> – use vinegar or citrus juice (such as lemon or lime) to add flavour to salads, marinades and sauces without relying on oil</p> </li> <li> <p><strong>use natural moisture</strong> – use the natural moisture in ingredients such as tomatoes, onions and mushrooms to cook dishes without adding extra oil. They release moisture as they cook, helping to prevent sticking.<!-- Below is The Conversation's page counter tag.

Culinary legend closing famous restaurant

<p>Australian chef and TV presenter Kylie Kwong is closing the doors of her famous restaurant after three years. </p> <p>The Sydney-based chef has been in the culinary industry for 30 years and is known for her unique blend of Cantonese cuisine and native Australian ingredients.</p> <p>Her restaurant, Lucky Kwong in South Eveleigh, will close on June 26, a tough decision that she had to make amid the high costs of running a business. </p> <p>“Everyone is feeling it. I have never seen the restaurant industry in such tough times as it is right now,” she told the <em>Sydney Morning Herald</em>. </p> <p>Despite this, Kwong said she was lucky to have been in the hospitality industry and that she plans to "relax and reflect" during her break from the restaurant business. </p> <p>"For all the many challenges that come with being in the hospitality industry, I consider myself fortunate for I have had far more positive experiences than negative," she said.</p> <p>Kwong opened her restaurant in 2021, after she shut the doors on her previous Sydney venue, Billy Kwong in 2019.</p> <p>She said that she also planned to further her work with charities focused on First Nations and multicultural communities, as she looks for more opportunities to  “amplify other people’s stories”. </p> <p>“I’ll still be very much connected to the food industry, but just I’ll be doing it in a different way,”  she told the<em> ABC</em>. </p> <p>She also announced that she's "hanging up my restaurateur hat" on <a href="https://www.instagram.com/p/C7KkTNgSXw9/?img_index=1" target="_blank" rel="noopener">Instagram</a>, and thanked everyone who has supported her throughout this journey. </p> <p>Celebrity chefs, Nigella Lawson and Darren Robertson shared their well-wishes on her post. </p> <p>“I feel a pang knowing that the next time I come back to Sydney there won’t be your restaurant to make a beeline for, but I’m so happy for you to have the time to do what’s right for you,” Lawson said.</p> <p>Robertson said he had massive respect for her contribution to Australian food and added: “Now try and get some bloody rest before your next adventures!" </p> <p><em>Image: Instagram</em></p>

E-scooter hit and run victim embraced by Magpies club

<p>In a heartwarming display of community and sportsmanship, the Collingwood AFL club has come together to support a cherished fan, 81-year-old Jessie Hatch, after a distressing e-scooter incident following the Collingwood-Carlton game two weeks ago.</p> <p>Jessie, a lifelong devotee of the Magpies, was leaving the Melbourne Cricket Ground when she was <a href="https://www.oversixty.com.au/finance/legal/such-a-cowardly-thing-police-hunt-after-e-scooter-hit-and-run-on-81-year-old-woman" target="_blank" rel="noopener">struck by an e-scooter</a> in what she described from the hospital afterwards as "such a cowardly thing".</p> <p>In a touching twist, it was a member of the rival Carlton cheer squad who first rushed to her aid. Reflecting on the incident, Jessie <a href="https://www.9news.com.au/national/great-grandmother-embraced-by-beloved-magpies-after-ugly-escooter-incident/73445ba6-69f0-4954-8984-cc3109e3de30" target="_blank" rel="noopener">recounted to 9News</a>, "Apparently I passed out and they couldn't get a pulse or a heartbeat and I came around finally with someone screaming my name and telling me to wake up and also my son was so distressed."</p> <p>Jessie's son, Greg, expressed his confidence in his mother’s resilience. "She was born in Carlton - she won't admit that - but she was raised in Collingwood . . . So they build them a bit different when they're raised in Collingwood. Tougher than any of us."</p> <p>Despite her injuries, Jessie’s spirit remains unbroken. Dressed proudly in her Magpies jumper, she recently attended a training session where she was warmly welcomed and embraced by the players. </p> <p>The club’s support has been a balm for Jessie. "This is just amazing," she beamed. True to her unwavering dedication, she declared, "I'm going to the game on Saturday. That won't keep me away."</p> <p>In an inspiring gesture of goodwill, Jessie also plans to set aside traditional rivalries to visit Princes Park and thank the Blues fan who helped her. </p> <p>Meanwhile, police have alleged that the e-scooter rider intentionally knocked Jessie down. To that end, a 46-year-old man remains in custody, with his next court appearance scheduled for May 22.</p> <p><em>Images: Nine News | Seven News<br /></em></p>

4 foods that ease heartburn

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

That includes the mass-produced wholegrain bread you buy from the supermarket.</p> <p>While this newly published research and associated <a href="https://www.bmj.com/content/385/bmj.q793">editorial</a> are unlikely to end the wrangling about how best to define unhealthy foods and diets, it’s critical those debates don’t delay the implementation of policies that are likely to actually improve our diets.</p> <h2>What are ultra-processed foods?</h2> <p><a href="https://pubmed.ncbi.nlm.nih.gov/30744710/">Ultra-processed foods</a> are industrially produced using a variety of processing techniques. They typically include ingredients that can’t be found in a home kitchen, such as preservatives, emulsifiers, sweeteners and/or artificial colours.</p> <p>Common examples of ultra-processed foods include packaged chips, flavoured yoghurts, soft drinks, sausages and mass-produced packaged wholegrain bread.</p> <p>In <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7719194/#CR13">many other countries</a>, ultra-processed foods make up a large proportion of what people eat. A <a href="https://pubmed.ncbi.nlm.nih.gov/31676952/">recent study</a> estimated they make up an average of 42% of total energy intake in Australia.</p> <h2>How do ultra-processed foods affect our health?</h2> <p>Previous <a href="https://pubmed.ncbi.nlm.nih.gov/33167080/">studies</a> have linked increased consumption of ultra-processed food with poorer health. High consumption of ultra-processed food, for example, has been associated with a <a href="https://pubmed.ncbi.nlm.nih.gov/38418082/">higher risk</a> of type 2 diabetes, and death from heart disease and stroke.</p> <p>Ultra-processed foods are typically high in energy, added sugars, salt and/or unhealthy fats. These have long been <a href="https://www.who.int/news-room/fact-sheets/detail/healthy-diet">recognised</a> as risk factors for a range of diseases.</p> <p>It has also been suggested that structural changes that happen to ultra-processed foods as part of the manufacturing process <a href="https://pubmed.ncbi.nlm.nih.gov/31105044/">may</a> lead you to eat more than you should. Potential explanations are that, due to the way they’re made, the foods are quicker to eat and more palatable.</p> <p>It’s also <a href="https://pubmed.ncbi.nlm.nih.gov/35952706/">possible</a> certain food additives may impair normal body functions, such as the way our cells reproduce.</p> <h2>Is it harmful? It depends on the food’s nutrients</h2> <p>The <a href="https://www.bmj.com/content/385/bmj-2023-078476">new paper</a> just published used 30 years of data from two large US cohort studies to evaluate the relationship between ultra-processed food consumption and long-term health. The study tried to disentangle the effects of the manufacturing process itself from the nutrient profile of foods.</p> <p>The study found a small increase in the risk of early death with higher ultra-processed food consumption.</p> <p>But importantly, the authors also looked at diet quality. They found that for people who had high quality diets (high in fruit, vegetables, wholegrains, as well as healthy fats, and low in sugary drinks, salt, and red and processed meat), there was no clear association between the amount of ultra-processed food they ate and risk of premature death.</p> <p>This suggests overall diet quality has a stronger influence on long-term health than ultra-processed food consumption.</p> <p>When the researchers analysed ultra-processed foods by sub-category, mass-produced wholegrain products, such as supermarket wholegrain breads and wholegrain breakfast cereals, were not associated with poorer health.</p> <p>This finding matches another recent <a href="https://pubmed.ncbi.nlm.nih.gov/38417577/">study</a> that suggests ultra-processed wholegrain foods are not a driver of poor health.</p> <p>The authors concluded, while there was some support for limiting consumption of certain types of ultra-processed food for long-term health, not all ultra-processed food products should be universally restricted.</p> <h2>Should dietary guidelines advise against ultra-processed foods?</h2> <p>Existing national <a href="https://www.eatforhealth.gov.au/sites/default/files/2022-09/n55_australian_dietary_guidelines.pdf">dietary</a> <a href="https://www.health.govt.nz/system/files/documents/publications/eating-activity-guidelines-new-zealand-adults-updated-2020-oct22.pdf">guidelines</a> have been developed and refined based on decades of nutrition evidence.</p> <p>Much of the recent evidence related to ultra-processed foods tells us what we already knew: that products like soft drinks, alcohol and processed meats are bad for health.</p> <p>Dietary guidelines <a href="https://pubmed.ncbi.nlm.nih.gov/35184508/">generally</a> already advise to eat mostly whole foods and to limit consumption of highly processed foods that are high in refined grains, saturated fat, sugar and salt.</p> <p>But some nutrition researchers have <a href="https://www.bmj.com/content/384/bmj.q439">called</a> for dietary guidelines to be amended to recommend avoiding ultra-processed foods.</p> <p>Based on the available evidence, it would be difficult to justify adding a sweeping statement about avoiding all ultra-processed foods.</p> <p>Advice to avoid all ultra-processed foods would likely unfairly impact people on low-incomes, as many ultra-processed foods, such as supermarket breads, are relatively affordable and convenient.</p> <p>Wholegrain breads also provide important nutrients, such as fibre. In many countries, bread is the <a href="https://www.health.govt.nz/system/files/documents/publications/a-focus-on-nutrition-ch3_0.pdf">biggest contributor</a> to fibre intake. So it would be problematic to recommend avoiding supermarket wholegrain bread just because it’s ultra-processed.</p> <h2>So how can we improve our diets?</h2> <p>There is strong <a href="https://www.foodpolicyindex.org.au/_files/ugd/7ee332_a2fa1694e42f423195caf581044fccf1.pdf">consensus</a> on the need to implement evidence-based policies to improve population diets. This includes legislation to restrict children’s exposure to the marketing of unhealthy foods and brands, mandatory Health Star Rating nutrition labelling and taxes on sugary drinks.</p> <p>These policies are underpinned by <a href="https://pubmed.ncbi.nlm.nih.gov/37659696/">well-established systems</a> for classifying the healthiness of foods. If new evidence unfolds about mechanisms by which ultra-processed foods drive health harms, these classification systems can be updated to reflect such evidence. If specific additives are found to be harmful to health, for example, this evidence can be incorporated into existing nutrient profiling systems, such as the <a href="http://www.healthstarrating.gov.au/internet/healthstarrating/publishing.nsf/content/home">Health Star Rating</a> food labelling scheme.</p> <p>Accordingly, policymakers can confidently progress food policy implementation using the tools for classifying the healthiness of foods that we already have.</p> <p>Unhealthy diets and obesity are among the <a href="https://www.aihw.gov.au/reports/burden-of-disease/burden-of-disease-study-2018-key-findings/contents/key-findings">largest contributors</a> to poor health. We can’t let the hype and academic debate around “ultra-processed” foods delay implementation of globally recommended policies for improving population diets.<!-- Below is The Conversation's page counter tag.

"I killed them": Major twist in slain Aussie brothers case

<p>The girlfriend of the man who allegedly killed Perth brothers Callum and Jake Robinson has reportedly "flipped" on her partner, becoming the star witness in the case. </p> <p>Ari Gisel García Cota was arrested earlier this week, along with her partner Jesús Gerardo Garcia Cota and his brother Cristian Alejandro Garcia, after the bodies of the Robinson brothers and their friend were found on Saturday in a desolate section of Santo Tomas in the Baja California region.</p> <p>According to Mexico police, the three men were killed as a result of a failed robbery, after locals attempted to steal the tyres from their pick-up truck.</p> <p>The bodies of the three men were recovered from a 15-metre deep well, with each man having fatal gun shot wounds to the head. </p> <p>In a major twist to the case, prosecutors revealed to court on Wednesday that Ari Gisel García Cota had become a key witness in the case after turning on the "ringleader" of the crime. </p> <p>“She has flipped on the ringleader and the evidence she’s provided to the prosecution will lead this case going forward,” Nine News correspondent Alison Piotrowski, who was in the courtroom, told 2GB’s Ben Fordham on Thursday.</p> <p>“What’s alleged is that Jesús Gerardo was driving her car that night when he went out to that remote campsite. The prosecution is saying what we’ve been talking about for the last couple of days has potentially happened, that the two Aussies and their American friend were ambushed.”</p> <p>Prosecutors allege Jesús Gerardo “killed them, took their tyres, put the tyres on her car and drove back”.</p> <p>When he went back to their house, the court heard he allegedly told Ari Gisel, “I f**ked up three gringos (English-speaking foreigner).”</p> <p>“She said to him, ‘What do you mean by that?’ And he told her, ‘I killed them’, and then showed her the vehicle with Jake, Callum and Jack’s tyres on her car,” Piotrowski said.</p> <p>“Ari was arrested later that day, she had fled to her mother’s house to get away from him. When the officers arrested her they said, ‘You have the right to remain silent’, and she said, ‘I don’t want to be silent, I want to tell you what I know. I’m a victim of domestic violence, I want to protect my four-year-old so let me help you with this case.’ So she has spectacularly turned on him and will now be crucial in this case moving forward.”</p> <p>Piotrowski added that the stunning revelation explained why Mexican officials “have been able to put him behind bars so quickly and also how they found the bodies”.</p> <p>“This conversation that he had with his girlfriend is pretty damning,” she said.</p> <p>So far only Jesús Gerardo Garcia Cota has been charged in connection with the deaths of the three men, and only with forced kidnapping, while Ari Gisel García Cota and Cristian Alejandro Garcia have only been charged with drug possession.</p> <p>Piotrowski said the kidnapping charges may not be upgraded to murder until the next court hearing, although the judge has more questions about how the three men were killed. </p> <p>“The judge did say that he can’t understand how one sole person could have done this, essentially kidnap and kill three men and take their tyres, it seems like too much,” she said.</p> <p>“He suggested that the prosecution needed to look into more suspects, that they needed to broaden their investigation because it couldn’t have been done by one man alone.”</p> <p><em>Image credits: Instagram / State Commission of the Penitentiary System of Baja California</em></p>
