Been drinking and your heart’s fluttering? You may have ‘holiday heart’

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/caleb-ferguson-72">Caleb Ferguson</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> and <a href="https://theconversation.com/profiles/sabine-allida-2236436">Sabine Allida</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a></em></p> <p>It’s the time of year for workplace Christmas parties, and gatherings with family and friends. Maybe you’ll drink a lot in one go.</p> <p>Then you feel your heart beating fast or irregularly. Maybe there’s a flutter in your chest or neck. Maybe you feel dizzy or short of breath. You may feel so concerned you go to the emergency department.</p> <p>After a few tests, you’re told you have “alcohol-induced atrial arrhythmia”. In plain English, that’s an irregular heartbeat brought on by excessive, or binge drinking.</p> <p>The condition is common at this time of year. That’s why it’s also called “<a href="https://www.sciencedirect.com/science/article/abs/pii/000287037890296X">holiday heart</a>”.</p> <h2>What is holiday heart?</h2> <p>Every festive season, emergency departments see more people with <a href="https://www.cambridge.org/core/journals/prehospital-and-disaster-medicine/article/impact-of-alcoholrelated-presentations-to-emergency-departments-on-days-with-a-public-holiday-or-sporting-event-a-retrospective-cohort-study/174603C0385FE6FCEBBAEA1A10DB25BD">alcohol-related issues</a> and <a href="https://www.heartlungcirc.org/article/S1443-9506(16)30583-2/pdf">irregular heart rhythms</a>.</p> <p>People often present with a fast or irregular heartbeats associated with binge drinking, overeating, dehydration and increased stress over the silly season – all contributing factors.</p> <p>We’ve known about holiday heart (or holiday heart syndrome) for <a href="https://www.sciencedirect.com/science/article/abs/pii/000287037890296X">almost 50 years</a>. Back in the 1970s, it was described as an abnormal heart rhythm (or arrythmia) in healthy people without heart disease after binge drinking alcohol. Doctors often saw this after weekends and public holidays, including the festive season.</p> <p>But an abnormal heart rhythm related to alcohol <a href="https://www.sciencedirect.com/science/article/pii/S2405500X22009379#bib2">isn’t limited</a> to the holidays and weekends. We also see it in people who binge drink at any time of year, or in people who drink heavily over many years.</p> <h2>What causes it? How is it diagnosed?</h2> <p>Alcohol affects your <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5513687/">heart, blood vessels, blood</a> and nervous system in many ways.</p> <p>For instance, when alcohol disrupts your nervous system, it can lead to dehydration and inflammation. In turn, this can cause disruption to the heart’s electrical system, which can lead to an <a href="https://pubmed.ncbi.nlm.nih.gov/28867013/">irregular heartbeat</a>.</p> <p>People may go to hospital with heart flutters, chest pain, fainting or passing out (syncope) and shortness of breath (dyspnoea). But an irregular heartbeat can also occur without symptoms, and may only be discovered when investigating other health issues.</p> <p>If you have symptoms, go to your emergency department or GP. Health professionals will likely run some tests to diagnose heart-related rhythm problems.</p> <p>These include monitoring the heart’s rhythm using an ECG or electrocardiogram. This simple and non-invasive test involves attaching some electrodes to your chest, arms and legs to produce a graph of electrical signals from the heart. Clinicians are often interested in the “p wave”, which represents the electrical activation of the upper chambers of the heart.</p> <p>You may also have a blood test to look at your electrolyte levels (essential minerals in your blood). A blood test may also test for markers of clotting and inflammation, as well as kidney and liver function.</p> <h2>Why are we concerned about it?</h2> <p>The vast majority of people diagnosed with holiday heart will recover, especially if treated early or if they stop or limit drinking alcohol.</p> <p>However, some people will be diagnosed with <a href="https://theconversation.com/getting-to-the-heart-of-the-matter-on-stroke-7180">atrial fibrillation</a> – the <a href="https://www.heartlungcirc.org/article/S1443-9506(18)31778-5/fulltext">most common</a> heart rhythm disorder in Australian adults, affecting <a href="https://www.sciencedirect.com/science/article/pii/S1443950617304845">1.4-5.5%</a> of the population.</p> <p>If so, this may require medicines to restore a regular heartbeat (known as <a href="https://www.svhhearthealth.com.au/procedures/procedures-treatments/cardioversion">cardioversion</a>), electrical cardioversion (using a defibrillator to apply an electric shock to the heart) or a procedure called <a href="https://www.heart.org/en/health-topics/arrhythmia/prevention--treatment-of-arrhythmia/ablation-for-arrhythmias">cardiac ablation</a>.</p> <p>If atrial fibrillation is left untreated, there’s an increased risk of blood clots, stroke and a heart attack.</p> <h2>How can you prevent it?</h2> <p>There is no definitive number of drinks known to trigger holiday heart. So our best advice to prevent it is to avoid binge drinking. Australian <a href="https://www.nhmrc.gov.au/health-advice/alcohol">guidelines</a> recommend women and men limit alcohol to no more than ten standard drinks a week and no more than four standard drinks on any one day.</p> <p>We’d also recommend drinking water between alcoholic drinks. This can help reduce the dehydrating effects of alcohol and reduce the risk of alcohol-induced heart rhythm complications.</p> <p>Then do your best to <a href="https://journals.sagepub.com/doi/full/10.1177/2156587214543143">reduce stress</a>, keep up with exercise and eat a diet that’s <a href="https://www.heartfoundation.org.au/healthy-living/healthy-eating/heart-healthy-eating-pattern">good for your heart</a> – all general advice for looking after your heart, whether or not you’re drinking alcohol.</p> <p>Taking these steps will help reduce your risk of holiday heart and keep your heart healthy this festive season.</p> <hr /> <p><em>Information about alcohol and the heart is available from the <a href="https://www.heartfoundation.org.au/blog/alcohol-and-heart-health">Heart Foundation</a>.

Retiring with debt? Experts explain downsizing, using super for your mortgage, and pension eligibility

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/kathleen-walsh-218536">Kathleen Walsh</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/jemma-briscoe-2234812">Jemma Briscoe</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a></em></p> <p>About <a href="https://cepar.edu.au/sites/default/files/cepar-research-brief-housing-ageing-australia.pdf">36%</a> of homeowners still have a mortgage when they retire, up from 23% a decade ago.</p> <p>This increase in mortgage debt is due to soaring property prices, <a href="https://www.mlc.com.au/content/dam/mlc/documents/pdf/retirement/retirement-reports-housing-report.pdf">changes in retirement ages</a> and easy access to <a href="https://www.dss.gov.au/our-responsibilities/seniors/benefits-payments/home-equity-access-scheme">drawdown equity loans</a> (where you use your home as security to get a loan, which can be used to fund travel, medical costs and other expenses).</p> <p>So, what are the options for homeowners who carry debt into retirement?</p> <h2>Option 1: keeping the home and the debt</h2> <p>If you keep the family home in retirement, you get to own a property and can still receive the <a href="https://www.dva.gov.au/get-support/financial-support/income-support/what-changes-your-payments/your-property-or-accommodation/how-owning-home-can-affect-pensions-and-payments">age pension</a>.</p> <p>For example: Jackie has a home worth A$2 million with a $200,000 mortgage. She also has $800,000 in superannuation. She is 67 but is not eligible for the age pension because her <a href="https://moneysmart.gov.au/how-super-works/tax-and-super#:%7E:text=If%20you're%20aged%2060%20or%20over%20and%20withdraw%20a,as%20a%20public%20sector%20fund.">assessable assets</a> – her super – is above the $695,500 cut off.</p> <p>If Jackie takes $200,000 from her super and repays the outstanding mortgage debt, she will save on interest and principal repayments for the next ten years. She will also reduce her assessable assets by $200,000. This makes her eligible for a part pension.</p> <p>So while Jackie has less super, she gets to receive a pension and gets all the subsidies associated with being a pensioner.</p> <h2>Option 2: downsizing to clear the debt</h2> <p>Downsizing can extinguish any remaining debt, and can free up money for holidays, restaurants and the good life in retirement. It also enables a move to a more age-friendly home or apartment.</p> <p>And the government does provide a superannuation incentive via the <a href="https://www.ato.gov.au/individuals-and-families/super-for-individuals-and-families/super/growing-and-keeping-track-of-your-super/how-to-save-more-in-your-super/downsizer-super-contributions">downsizing contribution</a>.</p> <p>This allows homeowners over 55 who have lived in their home for more than ten years to make a one-off contribution of $300,000 (singles) and $600,000 (couples) to their super, using money from the sale of their home.</p> <p>But when a person reaches pension age, currently 67, any money in super will be included in <a href="https://www.servicesaustralia.gov.au/deeming?context=22526">the government’s assessment</a> of your financial assets and income. It could mean you don’t qualify for a pension or pensioner subsidies.</p> <p>Of the approximately 2.6 million who receive a part or full the age pension, only <a href="https://www.ato.gov.au/about-ato/research-and-statistics/in-detail/super-statistics/downsizer-super-contributions-data">78,000 people</a> have taken up this initiative. That begs the question if this option really does create a true financial downsizing incentive.</p> <p>Think again of Jackie, the woman with the $2 million home and the $200,000 in mortgage debt. Say she decides to sell her home and move to a smaller house close to family and friends. This will incur about $40,000 in selling and marketing fees, and stamp duty of around $62,000 on her new $1.4 million apartment.</p> <p>Downsizing leaves her with $1.1 million in financial assets (after transaction costs), which means that Jackie is not eligible for the pension.</p> <p>While she’ll be able to fund a comfortable lifestyle, this decision to downsize may not be as attractive as keeping the house.</p> <p>The decision to sell and move has cost her an extra $100,000 in transaction costs and her pension.</p> <p>So, people need to think carefully about downsizing. It can allow people to move closer to children, grandchildren, and the services they need – but these must be balanced against the financial implications.</p> <h2>What about renters?</h2> <p>Paying market rent while on a fixed income can be very hard, so renting is a challenge for retirees.</p> <p>According to the <a href="https://www.abs.gov.au/statistics/people/housing/housing-census/latest-release">2021 census</a>, women aged 55-64 and those over 65 are among the fastest-growing groups experiencing homelessness.</p> <p>The good news is many profit and not-for-profit retirement communities provide rental models and discounted entry contributions to residents with limited means (but there are often waiting lists).</p> <p>Retirement village residents may also be eligible for <a href="https://guides.dss.gov.au/social-security-guide/4/6/4/30">rent assistance</a> depending on their circumstances.</p> <p>Rent assistance is an extra $5,751 per year in social security benefits and provides extra financial support to <a href="https://guides.dss.gov.au/social-security-guide/5/1/7/10">eligible age pension recipients</a>.</p> <p>Retirement communities provide vulnerable older Australians a unique opportunity to move into a community under a leasehold or licence agreement. More than 260,000 senior Australians live in about <a href="https://www.propertycouncil.com.au/media-releases/retirement-living-construction-leads-wary-market">2,500 retirement communities</a> across the country.</p> <p>While a retirement village may not be the first option for many retirees, they can provide affordable accommodation.</p> <h2>Making the best choice</h2> <p>Navigating housing decisions as you approach retirement means balancing financial, emotional, and lifestyle considerations.</p> <p>Homeowners retiring with a mortgage face a choice: keep their home or downsize to alleviate debt.</p> <p>Keeping the home and accessing super to pay the outstanding debt improves cash flow and allows you to keep your biggest asset.</p> <p>Downsizing helps eliminate debt and boosts the super balance, but comes with extra transaction costs (and you may end up with less pension, or none at all).</p> <p>Seeking professional <a href="https://moneysmart.gov.au/financial-advice/choosing-a-financial-adviser">financial advice</a> is crucial, and ensure they are a registered <a href="https://moneysmart.gov.au/financial-advice/financial-advisers-register">financial advisor</a>.<!-- Below is The Conversation's page counter tag.

Why do I get so anxious after drinking? Here’s the science behind ‘hangxiety’

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/blair-aitken-1510537">Blair Aitken</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> and <a href="https://theconversation.com/profiles/rebecca-rothman-2231560">Rebecca Rothman</a>, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p>You had a great night out, but the next morning, anxiety hits: your heart races, and you replay every conversation from the night before in your head. This feeling, known as hangover anxiety or “<a href="https://adf.org.au/insights/what-is-hangxiety/">hangxiety</a>”, <a href="https://onlinelibrary.wiley.com/doi/10.1002/hup.2623">affects around 22%</a> of social drinkers.</p> <p>While for some people, it’s mild nerves, for others, it’s a wave of anxiety that feels impossible to ride out. The “Sunday scaries” may make you feel panicked, filled with dread and unable to relax.</p> <p>Hangover anxiety can make even simple tasks feel overwhelming. Here’s why it happens, and what you can do about it.</p> <h2>What does alcohol do to our brains?</h2> <p>A hangover is the body’s way of recovering after drinking alcohol, bringing with it a range of symptoms.</p> <p><a href="https://www.mdpi.com/2077-0383/10/23/5691">Dehydration and disrupted sleep</a> play a large part in the pounding headaches and nausea many of us know too well after a big night out. But hangovers aren’t just physical – there’s a strong mental side too.</p> <p>Alcohol is a nervous system depressant, meaning it alters how certain chemical messengers (or neurotransmitters) behave in the brain. Alcohol relaxes you by increasing <a href="https://my.clevelandclinic.org/health/articles/22857-gamma-aminobutyric-acid-gaba">gamma-aminobutyric acid</a> (GABA), the neurotransmitter that makes you feel calm and lowers inhibitions. It decreases <a href="https://my.clevelandclinic.org/health/articles/22839-glutamate">glutamate</a> and this also slows down your thoughts and helps ease you into a more relaxed state.</p> <p>Together, this interaction affects your mood, emotions and alertness. This is why when we drink, we often feel more sociable, carefree and willing to let our guard down.</p> <p>As the effects of the alcohol wear off, your brain works to rebalance these chemicals by <a href="https://www.sciencedirect.com/science/article/pii/S0191886918305762">reducing GABA and increasing glutamate</a>. This shift has the opposite effect of the night before, causing your brain to become more excitable and overstimulated, which can lead to feelings of anxiety.</p> <p>So why do some people get hangxiety, while others don’t? There isn’t one clear answer to this question, as several factors can play a role in whether someone experiences hangover-related anxiety.</p> <h2>Genes play a role</h2> <p>For some, a hangover is simply a matter of how much they drank or how hydrated they are. But genetics may also play a significant role. <a href="https://onlinelibrary.wiley.com/doi/10.1111/add.12699">Research</a> shows your genes can explain almost half the reason why you wake up feeling hungover, while your friend might not.</p> <p>Because genes influence how your body processes alcohol, some people may experience more intense hangover symptoms, such as headaches or dehydration. These stronger physical effects can, in turn, <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1002/hup.2623">trigger anxiety during a hangover</a>, making you more susceptible to “hangxiety.”</p> <h2>Do you remember what you said last night?</h2> <p>But one of the most common culprits for feeling anxious the next day is often <a href="https://journals.sagepub.com/doi/pdf/10.1177/0091450915604988">what you do while drinking</a>.</p> <p>Let’s say you’ve had a big night out and you can’t quite recall a conversation you had or something you did. Maybe you acted in ways that you now regret or feel embarrassed about. You might fixate on these thoughts and get trapped in a cycle of worrying and rumination. This cycle can be hard to break and can make you feel more anxious.</p> <p><a href="https://doi.org/10.1016/j.addbeh.2023.107619">Research</a> suggests people who already struggle with feelings of anxiety in their day-to-day lives are especially vulnerable to hangxiety.</p> <p>Some people drink alcohol to unwind after a stressful day or to make themselves feel more comfortable at social events. This often leads to <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC9756407">heavier consumption</a>, which can make hangover symptoms more severe. It can also begin a cycle of drinking to feel better, making hangxiety even harder to escape.</p> <h2>Preventing hangover anxiety</h2> <p>The best way to prevent hangxiety is to limit your alcohol consumption. The <a href="https://adf.org.au/reducing-risk/alcohol/alcohol-guidelines">Australian guidelines</a> recommend having no more than ten standard drinks per week and no more than four standard drinks on any one day.</p> <p>Generally, the more you drink, the more intense your hangover symptoms might be, and the worse you are likely to feel.</p> <p>Mixing other drugs with alcohol can also increase the risk of hangxiety. This is especially true for party drugs, such as ecstasy or MDMA, that give you a temporary high but can lead to anxiety as they wear off and you are <a href="https://adf.org.au/insights/drug-comedowns">coming down</a>.</p> <p>If you do wake up feeling anxious:</p> <ul> <li> <p>focus on the physical recovery to help ease the mental strain</p> </li> <li> <p>drink plenty of water, eat a light meal and allow yourself time to rest</p> </li> <li> <p>try <a href="https://www.headspace.com/mindfulness/mindfulness-101">mindfulness meditation</a> or deep breathing exercises, especially if anxiety keeps you awake or your mind races</p> </li> <li> <p>consider journalling. This can help re-frame anxious thoughts, put your feelings into perspective and encourage self-compassion</p> </li> <li> <p>talk to a close friend. This can provide a safe space to express concerns and feel less isolated.</p> </li> </ul> <p>Hangxiety is an unwelcome guest after a night out. Understanding why hangxiety happens – and how you can manage it – can make the morning after a little less daunting, and help keep those anxious thoughts at bay.<!-- Below is The Conversation's page counter tag.

What is methanol? How does it get into drinks and cause harm?

It means methanol is processed differently in our bodies and is much more toxic than ethanol.</p> <p>Methanol is used in a <a href="https://pubchem.ncbi.nlm.nih.gov/compound/Methanol">variety of industrial and household products</a>, such as windshield cleaning fluids, antifreeze and fuel. It’s not safe for human consumption.</p> <h2>What makes methanol toxic?</h2> <p>The difference is in how methanol is metabolised, or broken down in our bodies.</p> <p>Ethanol is metabolised into a chemical compound called acetaldehyde. Acetaldehyde is toxic, but is rapidly converted to acetate (also known as acetic acid, found in vinegar). Generating an acid may sound bad, but acetate actually <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6699882/">produces energy and makes important molecules</a> in the body.</p> <p>By contrast, methanol is metabolised into <a href="https://www.cancer.gov/about-cancer/causes-prevention/risk/substances/formaldehyde">formaldehyde</a> (a chemical used in <a href="https://www.safework.nsw.gov.au/hazards-a-z/hazardous-chemical/priority-chemicals/formaldehyde">industrial glues</a> and for embalming corpses, for example) and then to <a href="https://pubchem.ncbi.nlm.nih.gov/compound/Formic-Acid">formic acid</a> (the chemical in some ant bites that makes them hurt so much).</p> <p>Unlike acetate, which the body uses, formic acid <a href="https://pubmed.ncbi.nlm.nih.gov/1665561/">poisons the mitochondria</a>, the powerhouses of the cells.</p> <p>As a result, a person exposed to methanol can go into severe <a href="https://www.ncbi.nlm.nih.gov/books/NBK482121/">metabolic acidosis</a>, which is when too much acid builds up in the body.</p> <p>Methanol poisoning can cause nausea, vomiting, and abdominal pain. The acidosis then causes depression of the central nervous system which can cause people with methanol poisoning to fall unconscious and go into a coma, as well as retinal damage leading to vision loss. This is because the retinas are full of active mitochondria and sensitive to them being damaged.</p> <p>Death is not inevitable if only a small amount of methanol has been consumed, and rapid treatment will greatly reduce damage.</p> <p>However, permanent vision damage can occur even at <a href="https://www.ncbi.nlm.nih.gov/books/NBK482121/">non-lethal doses</a> if treatment is not administered quickly.</p> <h2>What does treatment involve?</h2> <p><a href="https://www.ncbi.nlm.nih.gov/books/NBK482121/">Treatment</a> is mainly supportive care, such as intubation and mechanical ventilation to help the patient to breathe.</p> <p>But it can also involve drugs such as <a href="https://go.drugbank.com/drugs/DB01213">fomepizole</a> (which inhibits the generation of toxic formic acid) and dialysis to remove methanol and its metabolites from the body.</p> <h2>How does methanol get into alcoholic drinks?</h2> <p>Methanol can turn up in any alcoholic beverage, but it’s most likely in beverages with higher alcohol content, such as spirits, and traditionally brewed drinks, such as fruit wines.</p> <p>Methanol can get into alcoholic beverages in a number of ways. Sometimes it’s added <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8303512/">deliberately and illegally</a> during or after manufacturing as a cheaper way to increase the alcohol content in a drink.</p> <p><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5028366/">Traditional brewing methods</a> can also inadvertently generate methanol as well as ethanol and produce toxic levels of methanol depending on the microbes and the types of plant materials used in the fermentation process.</p> <p>We don’t yet know how the Australian teenagers came to be poisoned in this tragedy. But it is a good idea when travelling (particularly in areas with traditionally fremented drinks, such as south-east Asia, the Indian subcontinent and parts of Africa) to always be careful.</p> <p>The Australian government’s <a href="https://www.smartraveller.gov.au/before-you-go/safety/partying#methanol">Smartraveller website</a> advises that to avoid methanol poisoning you should be careful drinking cocktails and drinks made with spirits, drink only at reputable licensed premises and avoid home-made alcoholic drinks.</p> <p>Drinking only mass-produced commercial brews can be safer, though understandably people often want to try locally made drinks as part of their adventure.<!-- Below is The Conversation's page counter tag.

Matcha is having a moment. What are the health benefits of this green tea drink?

<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">University of South Australia</a></em></p> <p>Matcha has experienced a surge in popularity in recent months, leading to reports of <a href="https://www.smh.com.au/goodfood/sydney-eating-out/global-matcha-shortage-hits-australia-as-skyrocketing-popularity-rivals-coffee-20241101-p5kn6v.html">global shortages</a> and price increases.</p> <p>If you haven’t been caught up in the craze, matcha is a powdered version of green tea. On a cafe menu you might see a hot or iced matcha latte, or even a matcha-flavoured cake or pastry. A quick google brings up <a href="https://www.foodandwine.com/tea/matcha-tea/matcha-recipes">countless recipes</a> incorporating matcha, both sweet and savoury.</p> <p>Retailers and cafe owners <a href="https://www.smh.com.au/goodfood/sydney-eating-out/global-matcha-shortage-hits-australia-as-skyrocketing-popularity-rivals-coffee-20241101-p5kn6v.html">have suggested</a> the main reasons for matcha’s popularity include its “instagrammable” looks and its purported health benefits.</p> <p>But what are the health benefits of matcha? Here’s what the evidence says.</p> <h2>First, what is matcha?</h2> <p><a href="https://www.mdpi.com/1420-3049/26/1/85">Matcha</a> is a finely ground powder of green tea leaves, which come from the plant <em>Camellia sinensis</em>. This is the same plant used to make green and black tea. However, the <a href="https://naokimatcha.com/blogs/articles/how-matcha-is-made-in-japan">production process</a> differentiates matcha from green and black tea.</p> <p>For matcha, the tea plant is grown in shade. Once the leaves are harvested, they’re steamed and dried and the stems are removed. Then the leaves are carefully ground at controlled temperatures to form the powder.</p> <p>The <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6571865/">production process</a> for green tea is simpler. The leaves are picked from the unshaded plants, heated and then dried. We then steep the dried leaves in hot water to get tea (whereas with matcha the whole leaf is consumed).</p> <p>With black tea, after the leaves are picked they’re exposed to air, which leads to oxidation. This makes the leaves black and gives the tea a different flavour.</p> <h2>A source of phytonutrients</h2> <p>Phytonutrients are <a href="https://theconversation.com/phytonutrients-can-boost-your-health-here-are-4-and-where-to-find-them-including-in-your-next-cup-of-coffee-132100">chemical compounds found in plants</a> which have a range of benefits for human health. Matcha contains several.</p> <p>Chlorophyll gives plants such as <em>Camellia sinensis</em> their green colour. There’s some evidence chlorophyll may have <a href="https://www.mdpi.com/2223-7747/12/7/1533">health benefits</a> – including anti-inflammatory, anti-cancer and anti-obesity effects – due to its antioxidant properties. Antioxidants neutralise free radicals, which are unstable molecules that harm our cells.</p> <p>Theanine has been shown to <a href="https://www.mdpi.com/2504-3900/91/1/32">improve sleep</a> and <a href="https://link.springer.com/article/10.1007/s11130-019-00771-5?crsi=662497574&amp;cicada_org_src=healthwebmagazine.com&amp;cicada_org_mdm=direct">reduce stress and anxiety</a>. The only <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/theanine">other known</a> dietary source of theanine is mushrooms.</p> <p>Caffeine is a phytonutrient we know well. Aside from increasing alertness, caffeine has also demonstrated <a href="https://www.tandfonline.com/doi/full/10.1080/10408398.2022.2074362?casa_token=ADALIs6M3iAAAAAA%3AXpY35se0zLddAEIbZAaeCcDaNWm94s2WJaDHfXDRvVZgYq_xTxsCFuvtrtNXMXAL9uNIvLlYzO30aA#abstract">antioxidant effects</a> and some protection against a range of chronic and neurodegenerative diseases. However, too much caffeine can have negative side effects.</p> <p>Interestingly, shading the plants while growing appears to <a href="https://scijournals.onlinelibrary.wiley.com/doi/pdfdirect/10.1002/jsfa.9112?casa_token=KxVD9i9p4BsAAAAA:OwGTauXFHAndyJkam8WuXrmGQ2k1kaSRu5pOqJOrhSyRSeWkDwdrI23qaD5WVH1HGqZLFdsjP9ZTvolw">change the nutritional composition</a> of the leaf and may lead to higher levels of these phytonutrients in matcha compared to green tea.</p> <p>Another compound worth mentioning is called catechins, of which there are several different types. Matcha powder similarly has <a href="https://theconversation.com/matcha-tea-what-the-current-evidence-says-about-its-health-benefits-202782">more catechins</a> than green tea. They are strong antioxidants, which <a href="https://link.springer.com/article/10.1186/s41702-020-0057-8">have been shown</a> to have protective effects against bacteria, viruses, allergies, inflammation and cancer. Catechins <a href="https://www.sciencedirect.com/topics/medicine-and-dentistry/catechin#:%7E:text=Catechin%20is%20naturally%20present%20in,containing%20many%20catechins%20%5B130%2C131%5D.">are also found</a> in apples, blueberries and strawberries.</p> <h2>What are the actual health benefits?</h2> <p>So we know matcha contains a variety of phytonutrients, but does this translate to noticeable health benefits?</p> <p>A review published in 2023 identified only <a href="https://www.sciencedirect.com/science/article/pii/S2665927122002180">five experimental studies</a> that have given matcha to people. These studies gave participants about 2–4g of matcha per day (equivalent to 1–2 teaspoons of matcha powder), compared to a placebo, as either a capsule, in tea or in foods. Matcha decreased stress and anxiety, and improved memory and cognitive function. There was no effect on mood.</p> <p>A <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0309287">more recent study</a> showed 2g of matcha in older people aged 60 to 85 improved sleep quality. However, in <a href="https://www.mdpi.com/2072-6643/16/17/2907">younger people</a> aged 27 to 64 in another study, matcha had little effect on sleep.</p> <p>A <a href="https://link.springer.com/article/10.1007/s11130-022-00998-9">study in people with obesity</a> found no difference in the weight loss observed between the matcha group and the control group. This study did not randomise participants, and people knew which group they had been placed in.</p> <p>It could be hypothesised that given you consume all of the leaf, and given levels of some phytonutrients may be higher due to the growing conditions, matcha may have more nutritional benefits than green tea. But to my knowledge there has been no direct comparison of health outcomes from green tea compared to matcha.</p> <h2>There’s lots of evidence for green tea</h2> <p>While to date a limited number of studies have looked at matcha, and none compared matcha and green tea, there’s quite a bit of research on the health benefits of drinking green tea.</p> <p>A <a href="https://www.sciencedirect.com/science/article/pii/S0944711317300867?casa_token=dpbAEQQ7Is4AAAAA:U6aggqZM_G0KJ8hkhx0TGSvQywr4utlgKzwUnUj9x5t9eWd-FKENjbTvUv6s4TBTaPYrob-qQkk">systematic review of 21 studies</a> on green tea has shown similar benefits to matcha for improvements in memory, plus evidence for mood improvement.</p> <p>There’s also evidence green tea provides other health benefits. Systematic reviews have shown green tea leads to <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/ptr.6697?casa_token=1eAbmeGillYAAAAA%3ABNGBB6EuRFXIDWHgsa7E798wfC0MQK2r3yOmAlFzR2sxyD9Xt837VoCel0l6Tsh3RRO19t-YUm1GqO7Y">weight loss in people with obesity</a>, lower levels of <a href="https://link.springer.com/article/10.1186/s12937-020-00557-5">certain types of cholesterol</a>, and <a href="https://journals.lww.com/md-journal/fulltext/2020/02070/Effect_of_green_tea_supplementation_on_blood.36.aspx/1000">reduced blood pressure</a>. Green tea may also <a href="https://www.nature.com/articles/s41430-020-00710-7">lower the risk of certain types of cancer</a>.</p> <p>So, if you can’t get your hands on matcha at the moment, drinking green tea may be a good way to get your caffeine hit.</p> <p>Although the evidence on green tea provides us with some hints about the health benefits of matcha, we can’t be certain they would be the same. Nonetheless, if your local coffee shop has a good supply of matcha, there’s nothing to suggest you shouldn’t keep enjoying matcha drinks.</p> <p>However, it may be best to leave the matcha croissant or cronut for special occasions. When matcha is added to foods with high levels of added sugar, salt and saturated fat, any health benefits that could be attributed to the matcha may be negated.<!-- Below is The Conversation's page counter tag.

Don’t like drinking plain water? 10 healthy ideas for staying hydrated this summer

<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/the-university-of-queensland-805">The University of Queensland</a></em></p> <p>Have you heard the saying “water is life?” Well, it’s true.</p> <p>Water is an <a href="https://www.hsph.harvard.edu/nutritionsource/water/">essential nutrient</a>. Our body cannot produce sufficient water to live, so we need to consume water through food and fluids to survive.</p> <p>Maintaining hydration is one of the most fundamental components of good health. But lots of people don’t like drinking plain water much. The good news is there are many other healthy ways to help you stay hydrated.</p> <h2>Why hydration is important</h2> <p>Water is vital for many aspects of body functioning. About half our blood is “blood plasma”, which is over 90% water. Blood plasma is essential for carrying energy, nutrients and oxygen to the cells in the body that need it most. Water helps to remove waste products via the kidneys. It also helps keep joints lubricated, the digestive system functioning, the body’s temperature controlled and skin plump and strong.</p> <p>If you don’t consume enough water, you may experience symptoms of dehydration such as headaches, dizziness, tiredness, low concentration, constipation and a dry mouth. Being severely dehydrated increases the risk of <a href="https://www.kidney.org/atoz/content/kidneystones">kidney stones</a> and <a href="https://www.healthdirect.gov.au/urinary-tract-infection-uti">urinary tract infections</a>.</p> <p>If you feel thirsty, it means your body is already <a href="https://my.clevelandclinic.org/health/treatments/9013-dehydration#:%7E:text=If%20you're%20thirsty%2C%20you,life%2Dthreatening%20illnesses%20like%20heatstroke.">mildly dehydrated</a>, so make sure you pay attention to what your body is telling you.</p> <h2>How much fluid do you need?</h2> <p>The amount of fluid we need changes as we age. Relative to our body weight, our needs decrease. So, a newborn baby has higher fluid needs (per kilogram body weight) than their parent, and older adults have lower fluid needs than younger adults.</p> <p>Fluid requirements are related to metabolic needs and vary from person-to-person. The normal turnover of water in adults is approximately 4% of total body weight per day. So, for example, if you weigh 70 kilograms, you’ll lose about 2.5 to 3 litres of water a day (not including sweating). This means you will need to consume that amount of water from food and drinks to maintain your hydration.</p> <p>Eight cups (or two litres) a day is often <a href="https://www.npr.org/2022/09/21/1124371309/busting-common-hydration-water-myths?utm_source=npr_newsletter&amp;utm_medium=email&amp;utm_content=20221016&amp;utm_term=7386723&amp;utm_campaign=health&amp;utm_id=31926817&amp;orgid=&amp;utm_att1=">mentioned</a> as the amount of water we should aim for and a nice way to track your intake. But it doesn’t account for individual variation based on age, gender, body size and activity levels.</p> <p>Alcohol is a diuretic, which means it dehydrates the body by promoting water loss through urine. This fluid loss is a key factor that contributes to the severity of a hangover. Always have a glass of water in between alcoholic drinks to help stay hydrated.</p> <p>Caffeinated drinks (like tea and coffee) only have a mild diuretic effect. For most healthy adults, it’s okay to consume up to 400 mg of caffeine a day – that’s about four cups of coffee or eight cups of tea. If you drink more than this, it may impact your hydration levels.</p> <p>To check your specific requirements, check out the Australian <a href="https://www.nrv.gov.au/nutrients/water">guidelines</a> for fluid intake.</p> <h2>People who should take extra care</h2> <p>Some people are at greater risk of the harmful health effects from dehydration and need to pay special attention to their fluid intake.</p> <p>The highest priority groups are babies, young kids, pregnant women, and older adults. These groups are at greater risk for many reasons, including relatively higher water needs per kilo of body weight, reduced ability to detect and respond to symptoms of dehydration, and barriers to consuming fluids regularly.</p> <p>Family and friends can play an important role in <a href="https://www.agedcareguide.com.au/information/hydration-for-elderly-people-and-the-dangers-of-dehydration">supporting loved ones</a> to maintain hydration, especially during warm weather.</p> <h2><strong>Ten ideas for keeping fluids up this summer</strong></h2> <ol> <li> <p><strong>Download a water reminder app on your phone</strong> This will help keep you on track during the day and give you digital “high fives” when you hit your water goals.</p> </li> <li> <p><strong>Add sugar-free flavouring</strong> Try a sugar-free fruit infusion in your water to make it more appealing. Prepare a jug in the refrigerator and infuse it overnight so it’s chilled for you the next day. Fill it up and take it everywhere with you!</p> </li> <li> <p><strong>Add some fresh fruit</strong> Add some slices of lime, lemon, berries, pineapple or orange to your water bottle for some natural flavouring. If the bottle is kept in a fridge, the fruit will stay fresh for about three days.</p> </li> <li> <p><strong>Make a jug of iced tea (not the bottled stuff)</strong> There are many great sugar-free recipes online. Tea contributes to fluid intake too. For green and black teas, brew in boiling water then cool overnight on the bench before refrigerating. Fruit teas can be made using cold water immediately.</p> </li> <li> <p><strong>Add a dash of cordial to your water</strong> A small amount of cordial in your water is a healthier alternative to drinking a sugar-sweetened soft drink or fruit juice. Diet cordials have less added sugar again.</p> </li> <li> <p><strong>Make a fruit ‘slushie’</strong> Combine fresh fruit, ice and water at home in the morning and sip to increase your fluid intake for the day.</p> </li> <li> <p><strong>Buy a soda maker for your home</strong> Some people find plain water tastes better with bubbles. Sparkling mineral water is great too, as long as there is no added sugar or sweeteners.</p> </li> <li> <p><strong>Before you eat anything, have a glass of water</strong> Make it a rule with yourself to have a glass of water before every snack or meal.</p> </li> <li> <p><strong>Eat water-rich fruits and vegetables</strong> Many fruits and vegetables have a high water content. Some of the best include berries, oranges, grapes, carrots, lettuce, cabbage, spinach and melons. Keep a container full of cut-up fruit to snack on in your fridge.</p> </li> <li> <p><strong>Use a water bottle</strong> Take it with you during the day and keep it by your bed overnight.</p> </li> </ol> <h2>A tip on water bottles</h2> <p>Water bottles are everywhere and sometimes seem to offer <a href="https://www.refinery29.com/en-au/emotional-support-water-bottle-girlies-tiktok-trend">emotional support</a> as well as hydration.</p> <p>Having a water bottle you enjoy using can go a long way in helping you keep up your fluids during the day.</p> <p>Pay attention to the material of the water bottle and use one that helps you form good habits. Some people prefer metal water bottles as they can keep water cooler for longer (others feel like they are camping).

Kyle Sandilands throws drink at Ben Fordham live on-air

<p>Kyle Sandilands and Ben Fordham have clashed during a live interview. </p> <p>The radio rivals joined John Laws' on his 2SM show on Wednesday, for one of Laws' final shows before he retires when things got heated. </p> <p>The trio had been chatting about various topics for 15 minutes when the conversation turned to the US election. </p> <p>After Sandilands gave his opinion on Trump's strong performance, Fordham sarcastically responded with:  “Of all the experts on American politics, what an honour for John Laws to have Kyle Sandilands commenting on it this morning.”</p> <p>The comment sparked an immediate reaction from the KIIS FM host, who retaliated with: “I’ll throw this water in your face, b***h." </p> <p>"I don’t care who you think you are.”</p> <p>“Well go on, do it!” Fordham challenged him.</p> <p>The 2GB host pushed him over the edge when he said:  “You talk tough to the paparazzi …” and was cut off when Sandilands threw a tall glass of water over his face and chest. </p> <p>“Oh my lord!” a shocked Fordham said.</p> <p>“There you go,” Sandilands told him. “Don’t push a Brisbane boy.”</p> <p>Laws seemed rather amused by the chaos, and as Fordham tried to dry himself off, he took another cheeky dig at Sandilands. </p> <p>“Kyle’s wet too, but that’s perspiration,” he said.</p> <p>The interview went on for another 15 minutes and towards the end of the chat Laws apologised to Fordham saying: “I’m sorry you’re wet." </p> <p>“I bet you’ve never said that before,” quipped Sandilands.</p> <p>To make matters worse for Fordham, the NSW premier, Chris Minns was waiting just outside the studio doors. </p> <p>“I’ve got all this water all over me, it looks like I’ve wet myself, and now I’m going to go outside and there are VIPs out there,” Fordham said.</p> <p>“Embarrassing.”</p> <p>On Thursday morning, the KIIS FM radio host reflected on the on-air clash, claiming that he was the one who invited Fordham to appear with him on Laws' radio show. </p> <p>“I shouldn’t have invited him, I’ll never invite him anywhere again,” he said.</p> <p>“He just carried on like a carnival person,” Sandilands continued. “He kept yelling and he kept interfering.”</p> <p>In response, Fordham reportedly told <em>news.com.au</em>, “Kyle knows he’s boring on his own. That’s why he roped me in to join him.”</p> <p><em>Images: 2SM/ news.com.au</em></p>

New report reveals huge amount of super needed to retire

<p>Australians will need nearly $600,000 in their superannuation to retire comfortably, according to a new report. </p> <p>The Association of Superannuation Funds (ASFA) Retirement Standard report found that home-owning singles would need $595,000 to retire at 67 with a “comfortable” lifestyle, while a home-owning couple in relatively good health would need $690,000.</p> <p>This means that home-owning couples would need $73,337 per year while home-owning singles would need  $52,085 for a comfortable lifestyle. </p> <p>Their analysis also found that for a more modest lifestyle, a superannuation balance of $100,000 is needed for both singles or couples. </p> <p>Both budgets assume the retirees own their homes and are relatively healthy. </p> <p>On Wednesday, financial commentator Betsy Westcott told <em>Sunrise</em> that Aussies needed to start thinking about retirement earlier to make the most of their savings. </p> <p>“The longer that you contribute to super and pay attention it to it, the less you have to do to create that really golden retirement because age is your superpower,” Westcott said.</p> <p>“If you’re not paying attention to your super, which, let’s be honest, most of us aren’t, you could be missing out on some really big gains (to the overall balance).”</p> <p>She added that most people retired closer to 65 than 67 and ended up with a lot less superannuation than the benchmark. </p> <p>While the ASFA retirement standard took into account  “everyday spending,” Wescott said it did not factor in expenses like helping children buy a home, or buying into a retirement village.</p> <p>She also stressed that these benchmarks were just a guide saying:  "Personal finance is just that, it is personal.”</p> <p>“Your idea of a golden retirement will look different to your neighbour’s, your cousin’s, your best friend’s."</p> <p><em>Image: Shutterstock</em></p>

"Super uncomfortable for everyone": Qantas plays R-rated movie for every passenger

<p>Qantas has issued an apology after an R-rated movie was played for every passenger onboard a flight from Sydney to Tokyo. </p> <p>On Saturday, the flight was delayed by an hour due to problems with the in-flight entertainment system, which resulted in cabin crew only being able to play one film on everyone's individual screens. </p> <p>After requests were taken by passengers, the movie <em>Daddio</em> was chosen. </p> <p>The 2023 drama stars Sean Penn and Dakota Johnson as a taxi driver and his passenger as they discuss their relationships, including an affair Johnson’s character had with a married man.</p> <p>One passenger took to Reddit to share their experience of the flight, saying it was "extremely inappropriate", due to scenes of “graphic nudity and a lot of sexting”.</p> <p>“The kind where you could literally read the texts on screen without needing headphones,” the passenger wrote.</p> <p>“It was super uncomfortable for everyone, especially with families and kids on board.”</p> <p>Another passenger said the airline made the switch to <em>Inside Out 2</em> followed by a New Zealand nature show after playing “40 minutes of penis and boobs”.</p> <p>“These poor kids and the parents because y’all should’ve heard the audible gasps across the plane,” the passenger said.</p> <p>Cabin crew members attempted to fix the screens of those who didn't want to watch the R-rated film, but when this didn't work, resorted to switching the movie entirely. </p> <p>“The movie was clearly not suitable to play for the whole flight and we sincerely apologise to customers for this experience,” a Qantas spokesperson stated.</p> <p>“All screens were changed to a family-friendly movie for the rest of the flight, which is our standard practice for the rare cases where individual movie selection isn’t possible."</p> <p>“We are reviewing how the movie was selected.”</p> <p><em>Image credits: Shutterstock</em></p>

ATO urges Aussies to cash in on nearly $18 billion in lost or unclaimed super

<p>The Australian Taxation Office is urging people to check whether they are eligible to cash in on almost $17.8 billion in lost or unclaimed superannuation. </p> <p>Lost super is when your fund has lost touch with you or your account is inactive, and this can occur if you've changed your name, moved homes or changed jobs, without updating your details. </p> <p>The lost super becomes unclaimed when your fund transfers this lost money to the ATO. </p> <p>"Since 2021, the ATO has reunited almost $6.4 billion of unclaimed super with its owners. But there is still more than $17.8 billion waiting to be found,"<span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;"> ATO deputy commissioner Emma Rosenzweig said.</span></p> <p>"If you've changed jobs, moved house or simply forgotten to update your details, you may have lost or unclaimed super.</p> <p>"We're urging Australians to check if some of the $17.8 billion in lost and unclaimed super belongs to them."</p> <p>As of June 30, 2024, super funds and the ATO are holding lost super for over 7.1 million accounts, with retirees among those with lost or unclaimed super. </p> <p>The ATO revealed it was holding $471 million on behalf of those aged over 65. </p> <p>“Superannuation is a key part of your retirement, and we want to make sure Australians are claiming the investment they’ve worked for,” Rosenzweig said.</p> <p>You can check for lost super online through the <a href="https://www.ato.gov.au/individuals-and-families/super-for-individuals-and-families/super/growing-and-keeping-track-of-your-super/keeping-track-of-your-super/super-health-check#ato-Check3Checkforlostandunclaimedsuper" target="_blank" rel="noopener">ATO</a>. </p> <p>For those wanting to search for unclaimed cash, including unclaimed refunds, share dividends, uncashed cheques and more, you can visit <a href="https://asic.gov.au/for-consumers/unclaimed-money/" target="_blank" rel="noopener">federal</a> and state websites to see if you have anything owed to you. </p> <p>Unclaimed money is cash owed to people who can't be located, either due to name or address changes, lost paperwork or just forgot about the cash. </p> <p><em>Image: Shutterstock</em></p>

Cheeky diet soft drink getting you through the work day? Here’s what that may mean for your health

This is a great win for public health, given the <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2749350">recognised risks</a> of diets high in sugar-sweetened drinks.</p> <p>But over time, intake of diet soft drinks has <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7230225/">grown</a>. In fact, it’s so high that these products are now regularly <a href="https://www.sciencedirect.com/science/article/pii/S0160412020319188">detected in wastewater</a>.</p> <p>So what does the research say about how your health is affected in the long term if you drink them often?</p> <h2>What makes diet soft drinks sweet?</h2> <p>The World Health Organization (WHO) <a href="https://www.who.int/news/item/04-03-2015-who-calls-on-countries-to-reduce-sugars-intake-among-adults-and-children">advises</a> people “reduce their daily intake of free sugars to less than 10% of their total energy intake. A further reduction to below 5% or roughly 25 grams (six teaspoons) per day would provide additional health benefits.”</p> <p>But most regular soft drinks contain <a href="https://www.actiononsugar.org/surveys/2014/sugar-sweetened-beverages/">a lot of sugar</a>. A regular 335 millilitre can of original Coca-Cola contains at least <a href="https://www.coca-cola.com/ng/en/about-us/faq/how-much-sugar-is-in-cocacola-original-taste">seven</a> teaspoons of added sugar.</p> <p>Diet soft drinks are designed to taste similar to regular soft drinks but without the sugar. Instead of sugar, diet soft drinks contain artificial or natural sweeteners. The artificial sweeteners include aspartame, saccharin and sucralose. The natural sweeteners include stevia and monk fruit extract, which come from plant sources.</p> <p>Many artificial sweeteners are much sweeter than sugar so less is needed to provide the same burst of sweetness.</p> <p>Diet soft drinks are marketed as healthier alternatives to regular soft drinks, particularly for people who want to reduce their sugar intake or manage their weight.</p> <p>But while surveys of Australian <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7551593/">adults</a> and <a href="https://www.cambridge.org/core/journals/public-health-nutrition/article/adolescents-knowledge-and-beliefs-regarding-health-risks-of-soda-and-diet-soda-consumption/32F3E0FD6727F18F04C63F0390595131">adolescents</a> show most people understand the benefits of reducing their sugar intake, they often aren’t as aware about how diet drinks may affect health more broadly.</p> <h2>What does the research say about aspartame?</h2> <p>The artificial sweeteners in soft drinks are considered safe for consumption by food authorities, including in the <a href="https://www.fda.gov/food/food-additives-petitions/aspartame-and-other-sweeteners-food">US</a> and <a href="https://www.foodstandards.gov.au/consumer/additives/aspartame">Australia</a>. However, some <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4899993/">researchers</a> have raised concern about the long-term risks of consumption.</p> <p>People who drink diet soft drinks regularly and often are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4446768/">more likely</a> to develop certain metabolic conditions (such as diabetes and heart disease) than those who don’t drink diet soft drinks.</p> <p>The link was found even after accounting for other dietary and lifestyle factors (such as physical activity).</p> <p>In 2023, the WHO announced reports had found aspartame – the main sweetener used in diet soft drinks – was “<a href="https://www.who.int/news/item/14-07-2023-aspartame-hazard-and-risk-assessment-results-released">possibly carcinogenic to humans</a>” (carcinogenic means cancer-causing).</p> <p>Importantly though, the report noted there is not enough current scientific evidence to be truly confident aspartame may increase the risk of cancer and emphasised it’s safe to consume occasionally.</p> <h2>Will diet soft drinks help manage weight?</h2> <p>Despite the word “diet” in the name, diet soft drinks are not strongly linked with weight management.</p> <p>In 2022, the WHO conducted a <a href="https://www.who.int/news/item/15-05-2023-who-advises-not-to-use-non-sugar-sweeteners-for-weight-control-in-newly-released-guideline">systematic review</a> (where researchers look at all available evidence on a topic) on whether the use of artificial sweeteners is beneficial for weight management.</p> <p>Overall, the randomised controlled trials they looked at suggested slightly more weight loss in people who used artificial sweeteners.</p> <p>But the observational studies (where no intervention occurs and participants are monitored over time) found people who consume high amounts of artificial sweeteners tended to have an increased risk of higher body mass index and a 76% increased likelihood of having obesity.</p> <p>In other words, artificial sweeteners may not directly help manage weight over the long term. This resulted in the WHO <a href="https://www.who.int/news/item/15-05-2023-who-advises-not-to-use-non-sugar-sweeteners-for-weight-control-in-newly-released-guideline">advising</a> artificial sweeteners should not be used to manage weight.</p> <p><a href="http://www.cell.com/cell-metabolism/fulltext/S1550-4131(16)30296-0">Studies</a> in animals have suggested consuming high levels of artificial sweeteners can signal to the brain it is being starved of fuel, which can lead to more eating. However, the evidence for this happening in humans is still unproven.</p> <h2>What about inflammation and dental issues?</h2> <p>There is <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10817473/">some early evidence</a> artificial sweeteners may irritate the lining of the digestive system, causing inflammation and increasing the likelihood of diarrhoea, constipation, bloating and other symptoms often associated with irritable bowel syndrome. However, this study noted more research is needed.</p> <p>High amounts of diet soft drinks have <a href="https://bmcpublichealth.biomedcentral.com/articles/10.1186/s12889-023-17223-0">also been</a> linked with liver disease, which is based on inflammation.</p> <p>The consumption of diet soft drinks is also <a href="https://link.springer.com/article/10.1007/s40368-019-00458-0#:%7E:text=Diet%20soft%20drinks%20often%20have,2006">associated</a> with dental erosion.</p> <p>Many soft drinks contain phosphoric and citric acid, which can damage your tooth enamel and contribute to dental erosion.</p> <h2>Moderation is key</h2> <p>As with many aspects of nutrition, moderation is key with diet soft drinks.</p> <p>Drinking diet soft drinks occasionally is unlikely to harm your health, but frequent or excessive intake may increase health risks in the longer term.</p> <p>Plain water, infused water, sparkling water, herbal teas or milks remain the best options for hydration.<!-- 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>.

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>.

Super Rugby player dies at just 25

<p>New Zealand rugby player Connor Garden-Bachop has died aged 25.</p> <p>Police were called to the scene of a sudden death in Fendalton, Christchurch just before 6pm on Monday, according to the <em>NZ Herald</em>. </p> <p>“The death is not being treated as suspicious and will be referred to the Coroner,” police said.</p> <p>Garden-Bachop, son of former All Black Stephen Bachop, was part of the Highlanders' Super Rugby squad this season, and they have also confirmed his death in a statement shared on Facebook.</p> <p>“On behalf of the entire rugby community, the Highlanders, Wellington Rugby, New Zealand Rugby, the New Zealand Māori Rugby Board and the New Zealand Rugby Players Association would like to extend our deepest thoughts and love to the Garden-Bachop family,” the statement read.</p> <p>“Connor passed away on Monday following a medical event, and rugby’s collective focus at this time is on supporting his family.</p> <p>"All of rugby walks alongside the Garden-Bachop family at this time and we are collectively united in our grief," the statement continued. </p> <p>“Connor was a fantastic young player, an exciting New Zealand age-grade representative and a proud Māori All Black. Wherever he played, he was a committed and popular teammate with infectious energy and someone who could light up the room.</p> <p>“Most importantly, he was a loving father to his twin girls, a brother, a son and immeasurably loved by all those who knew him.</p> <p>“NZR, the New Zealand Māori Rugby Board, the Highlanders, Wellington Rugby and the Players Association are providing support and we ask that the privacy of the Garden-Bachop family is respected.”</p> <p>Garden-Bachop, an outside back, made his Highlanders debut in 2021. After five seasons with the team, the Highlanders announced on Facebook last week that he would not return to the team next season. </p> <p>The rugby player is survived by his twin daughters. </p> <p><em>Images: Instagram</em></p> <p> </p>

Super funds are using ‘nudges’ to help you make financial decisions. How do they work?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/fernanda-mata-1533222">Fernanda Mata</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a>; <a href="https://theconversation.com/profiles/breanna-wright-267597">Breanna Wright</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a>, and <a href="https://theconversation.com/profiles/liam-smith-5152">Liam Smith</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>Late last year the federal government announced <a href="https://ministers.treasury.gov.au/ministers/stephen-jones-2022/media-releases/government-unveils-comprehensive-financial-advice">measures</a> to make it easier for Australians to access financial advice.</p> <p>As part of this, the government wants super funds to use “nudges” to get members to engage more with their retirement investments and superannuation, especially when they’re starting work and approaching retirement.</p> <p>While the legislation containing the changes is still in the consultation phase, super funds are <a href="https://www.afr.com/companies/financial-services/super-funds-spend-big-ahead-of-advice-reforms-20240418-p5fkx6">upskilling staff</a> and making other changes to improve customer service or risk a government crackdown.</p> <p>Telling funds to use <a href="https://www.behaviourworksaustralia.org/blog/nudging-what-is-it-and-how-can-we-use-it-forgood">nudge theory</a> to advise on super comes as more than five million Australians are heading towards retirement.</p> <h2>What is nudge theory?</h2> <p>Nudging is used to encourage people to pick the “better” option, without taking away their freedom to choose differently.</p> <p>For example, sending regular reminders to members about the benefits of voluntary contributions can get them to increase the amount they put in. This nudge makes it easier for them to contribute more – the better option – while still allowing them to choose not to.</p> <p>Assistant Treasurer Stephen Jones <a href="https://ministers.treasury.gov.au/ministers/stephen-jones-2022/media-releases/government-unveils-comprehensive-financial-advice">explained</a> the government’s changes were needed because so-called “fin-fluencers” were providing unregulated financial advice on social media platforms to Australians unable to pay an adviser.</p> <h2>Helping people protect their interests</h2> <p>There are three ways, supported by research, nudges can help Australians engage with their super.</p> <p><strong>1. Future self visualisation</strong></p> <p>This involves getting young people to think about their <a href="https://www.halhershfield.com/considering-the-future-self">future selves</a> and visualise their life in retirement. This can help them to recognise the long-term benefits of getting actively involved with their super.</p> <p>Showing fund members how they might look when older by using an ageing filter software, for example, can make this visualisation more real for them and <a href="https://journals.sagepub.com/doi/full/10.1177/23794607231190607">enhance understanding of their future selves, leading to higher engagement</a>.</p> <p><strong>2. Simplification</strong></p> <p>We all know financial products and superannuation can be complicated. The information and choices presented can lead to <a href="https://thedecisionlab.com/biases/choice-overload-bias">decision paralysis</a>, causing people to delay or opt out of making a decision. By simplifying the process, funds can motivate people to get more engaged with their super.</p> <p>To get people to make voluntary contributions, for example, it might be more effective for funds to recommend <a href="https://siepr.stanford.edu/news/how-simple-nudge-can-motivate-workers-save-retirement">a specific percentage of their salary</a> rather than offering several options. Deciding whether to boost contributions by an extra 3%, 4% or 5% can be overwhelming, especially for people with poor <a href="https://theconversation.com/are-you-financially-literate-here-are-7-signs-youre-on-the-right-track-202331">financial literacy</a>.</p> <p><strong>3. Language and framing</strong></p> <p>The way options are framed and the language super funds use can significantly impact member engagement.</p> <p>Australians may be more likely to make higher voluntary contributions if they are asked how much they want <a href="https://www.bi.team/press-releases/the-small-nudges-that-could-make-young-people-142000-better-off-in-retirement/">to “invest” in their super </a> instead of how much they want to “contribute” or “add”.</p> <p>The word “invest” encourages people to think about future benefits, motivating them to make higher contributions.</p> <p>How options are labelled can also have an impact on <a href="https://www.bi.team/press-releases/the-small-nudges-that-could-make-young-people-142000-better-off-in-retirement/">member engagement</a> and decision making.</p> <p>For example, highlighting concrete benefits of different voluntary payments, such as “a 4% contribution keeps you above the poverty line”, and “a 10% contribution allows for a comfortable retirement according to Australian standards” can increase how much people are willing to contribute.</p> <h2>Ethical use of nudges</h2> <p>The <a href="https://www.superreview.com.au/news/superannuation/industry-body-backs-super-fund-nudges-though-parameters-need-be-set">Financial Services Council</a> backs the government on getting super funds to nudge members about contributions and investments but says there are limits.</p> <p>Parameters around nudging should be set […] to ensure that the language is appropriate and does not ultimately amount to defaulting.</p> <p>For example, letting a customer know that as they approach retirement, they need to make a decision about what retirement product they wish to utilise would be an acceptable nudge, while contacting a customer to let them know that they will be placed in a product when they retire, would not necessarily be acceptable.</p> <p>The council emphasises the importance of super funds recognising <a href="https://www.superreview.com.au/news/superannuation/industry-body-backs-super-fund-nudges-though-parameters-need-be-set">people’s autonomy</a> when delivering a “soft” or “hard” nudge.</p> <p>Soft nudges are gentle prompts and reminders designed to guide people to make good choices without pressuring them, such as sending an email reminder to review their investment options. Hard nudges are more direct in their guidance. These might include recommending specific investment options.</p> <p>Despite these differences, <a href="https://www.behaviourworksaustralia.org/blog/can-we-have-a-quiet-word-about-behavioural-science">ethical use of nudges</a> should encourage engagement while respecting people’s autonomy by making it easy for them to opt out.</p> <p>The use of nudges presents a valuable opportunity to increase superannuation fund members’ engagement.</p> <p>Whether through future self visualisation, simplification or language framing, ethical nudges can motivate members to take action, leading to greater confidence in navigating the retirement transition and achieving retirement goals.<!-- Below is The Conversation's page counter tag.

Weight loss: drinking a gallon of water a day probably won’t help you lose weight

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/duane-mellor-136502">Duane Mellor</a>, <a href="https://theconversation.com/institutions/aston-university-1107">Aston University</a></em></p> <p>It’s often claimed that if you’re trying to lose weight, one of the things you should do each day is drink plenty of water – with some internet advice even suggesting this should be as much as a gallon (about 4.5 litres). The claim is that water helps burn calories and reduce appetite, which in turn leads to weight loss.</p> <p>But while we all might wish it was this easy to lose weight, unfortunately there’s little evidence to back up these claims.</p> <h2>Myth 1: water helps burn calories</h2> <p>One <a href="https://pubmed.ncbi.nlm.nih.gov/14671205/">small study</a>, of 14 young adults, found drinking 500ml of water increased resting energy expenditure (the amount of calories our body burns before exercise) by about 24%.</p> <p>While this may sound great, this effect only lasted an hour. And this wouldn’t translate to a big difference at all. For an average 70kg adult, they would only use an additional 20 calories – a quarter of a biscuit – for every 500ml of water they drank.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/16822824/">Another study</a> of eight young adults only saw an increase in energy expenditure when the water was fridge cold – reporting a very modest 4% increase in calories burned. This may be because the body needs to use more energy in order to bring the water up to body temperature, or because it requires more energy for the body to filter the increased volume of fluid through the kidneys. And again, this effect was only seen for about an hour.</p> <p>So although scientifically it might be possible, the actual net increase in calories burned is tiny. For example, even if you drank an extra 1.5l of water per day, it would save fewer calories than you’d get in a slice of bread.</p> <p>It’s also worth noting that all this research was in young healthy adults. More research is needed to see whether this effect is also seen in other groups (such as middle-aged and older adults).</p> <h2>Myth 2: water with meals reduces appetite</h2> <p>This claim again seems sensible, in that if your stomach is at least partly full of water there’s less room for food – so you end up eating less.</p> <p>A number of studies actually support this, particularly those conducted in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2859815/#:%7E:text=Thus%2C%20when%20combined%20with%20a,meal%20EI%20following%20water%20ingestion.">middle-aged and older adults</a>. It’s also a reason people who are unwell or have a poor appetite are advised <a href="https://www.ageuk.org.uk/bp-assets/globalassets/salford/forms/improve-your-food-and-drink-intake.pdf">not to drink before eating</a> as it may lead to under-eating.</p> <p>But for people looking to lose weight, the science is a little less straightforward.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/17228036/">One study</a> showed middle-aged and older adults lost 2kg over a 12-week period when they drank water before meals compared with people who didn’t drink any water with their meal. Younger participants (aged 21-35) on the other hand did not lose any weight, regardless of whether they drank water before their meal or not.</p> <p>But since the study didn’t use blinding (where information which may influence participants is withheld until after the experiment is finished), it means that participants may have become aware of why they were drinking water before their meal. This may have led some participants to purposefully change how much they ate in the hopes it might increase their changes of losing weight. However, this doesn’t explain why the effect wasn’t seen in young adults, so it will be important for future studies to investigate why this is.</p> <p>The other challenge with a lot of this kind of research is that it only focuses on whether participants eat less during just one of their day’s meals after drinking water. Although this might suggest the potential to lose weight, there’s <a href="https://pubmed.ncbi.nlm.nih.gov/20736036/">very little good-quality evidence</a> showing that reducing appetite in general leads to weight loss over time.</p> <p>Perhaps this is due to our body’s biological drive to <a href="https://pubmed.ncbi.nlm.nih.gov/28193517/">maintain its size</a>. It’s for this reason that no claims can be legally made in Europe about foods which help make you <a href="https://www.cambridge.org/core/journals/proceedings-of-the-nutrition-society/article/satietyenhancing-products-for-appetite-control-science-and-regulation-of-functional-foods-for-weight-management/E4CCAE4C90A220994FD29C27FAE7F666">feel fuller for longer</a> with <a href="https://www.gov.uk/government/publications/nutrition-and-health-claims-guidance-to-compliance-with-regulation-ec-1924-2006-on-nutrition-and-health-claims-made-on-foods/nutrition-and-health-claims-guidance-to-compliance-with-regulation-ec-19242006#section-6">reference to weight loss</a>.</p> <p>So, although there might be some appetite-dulling effects of water, it seems that it might not result in long-term weight change – and may possibly be due to making conscious changes to your diet.</p> <h2>Just water isn’t enough</h2> <p>There’s a pretty good reason why water on its own is not terribly effective at <a href="https://www.cambridge.org/core/journals/proceedings-of-the-nutrition-society/article/eating-habits-and-appetite-control-a-psychobiological-perspective/0D0605739F5150D1A7C49420D75F3CDF">regulating appetite</a>. If it did, prehistoric humans might have starved.</p> <p>But while appetite and satiation – feeling full and not wanting to eat again – aren’t perfectly aligned with being able to <a href="https://pubmed.ncbi.nlm.nih.gov/20736036/">lose weight</a>, it might be a helpful starting point.</p> <p>Part of what helps us to feel full is our stomach. When food enters the stomach, it triggers stretch receptors that in turn lead to the release of hormones which tell us we’re full.</p> <p>But since water is a liquid, it’s rapidly emptied from our stomach – meaning it doesn’t actually fill us up. Even more interestingly, due to the <a href="https://pubmed.ncbi.nlm.nih.gov/16934271/">stomach’s shape</a>, fluids can bypass any semi-solid food content that’s being digested in the lower part of the stomach. This means that water can still be quickly emptied from the stomach. So even if it’s consumed at the end of a meal it might not necessarily extend your feelings of fullness.</p> <p>If you’re trying to eat less and lose weight, drinking excessive amounts of water may not be a great solution. But there is evidence showing when water is mixed with other substances (such as <a href="https://pubmed.ncbi.nlm.nih.gov/30166637/">fibre</a>, <a href="https://www.sciencedirect.com/science/article/pii/0031938494903034">soups</a> or vegetable sauces) this can delay how fast the stomach empties its contents – meaning you feel fuller longer.</p> <p>But while water may not help you lose weight directly, it may still aid in weight loss given it’s the healthiest drink we can choose. Swapping high-calorie drinks such as soda and alcohol for water may be an easy way of reducing the calories you consume daily, which may help with weight loss.<!-- Below is The Conversation's page counter tag.

Drinking lots of water may seem like a healthy habit – here’s when and why it can prove toxic

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a></em></p> <p>In late 2023, actor <a href="https://www.glamour.com/story/brooke-shields-recently-experienced-a-full-blown-seizure-and-bradley-cooper-came-running?utm_source=instagram&amp;utm_medium=social&amp;utm_content=instagram-bio-link&amp;client_service_id=31196&amp;client_service_name=glamour&amp;service_user_id=1.78e+16&amp;supported_service_name=instagram_publishing&amp;utm_brand=glm&amp;utm_social_type=owned">Brooke Shields</a> suffered a seizure after “flooding” her body with water. Shields became dangerously low on sodium while preparing for her show by drinking loads of water. “I flooded my system and I drowned myself,” she would later explain. “And if you don’t have enough sodium in your blood or urine or your body, you can have a seizure.”</p> <p>Shields said she found herself walking around outside for “no reason at all”, wondering: “Why am I out here?”</p> <blockquote> <p>Then I walk into the restaurant and go to the sommelier who had just taken an hour to watch my run through. That’s when everything went black. Then my hands drop to my side and I go headfirst into the wall.</p> </blockquote> <p>Shields added that she was “frothing at the mouth, totally blue, trying to swallow my tongue”.</p> <p>Like Shields, many people may be unaware of the dangers of drinking excessive amounts of water – especially because hydration is so often associated with health benefits. Models and celebrities <a href="https://www.teenvogue.com/story/drinking-water-flawless-skin#:%7E:text=If%20you're%20reading%20a,long%20hours%20at%20a%20time.">often advocate</a> drinking lots of water to help maintain clear, smooth skin. Some <a href="https://www.independent.co.uk/life-style/75-hard-challenge-before-and-after-tiktok-b2382706.html">social media influencers</a> have promoted drinking a gallon of water daily for weight loss.</p> <p>But excessive water consumption can cause <a href="https://patient.info/treatment-medication/hyponatraemia-leaflet">hyponatraemia</a> – a potentially fatal condition of low sodium in the blood.</p> <h2>Worried about hydration levels? Check your urine</h2> <p>The body strictly regulates its water content to maintain the optimum level of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2323003/">total body water</a> and “osmolality” – the concentration of dissolved particles in your blood. Osmolality increases when you are dehydrated and decreases when you have too much fluid in your blood.</p> <p>Osmolality is monitored by <a href="https://pubmed.ncbi.nlm.nih.gov/9074779/">osmoreceptors</a> that regulate sodium and water balance in the hypothalamus – the part of the brain that controls numerous hormones. These osmoreceptors signal the release of antidiuretic hormone (ADH), which acts on blood vessels and the kidneys to control the amount of water and salt in the body.</p> <figure><iframe src="https://www.youtube.com/embed/Qghf7Y9ILAs?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>In healthy people, the body releases ADH when osmolality becomes high. ADH tells the kidneys to reabsorb water, which makes urine more concentrated. The reabsorbed water dilutes the blood, bringing osmolality back to normal levels.</p> <p>Low blood osmolality suppresses the release of ADH, reducing how much water the kidneys reabsorb. This dilutes your urine, which the body then passes to rid itself of the excess water.</p> <p>Healthy urine should be clear and odourless. Darker, yellower urine with a noticeable odour can indicate dehydration – although medications and certain foods, including <a href="https://pubmed.ncbi.nlm.nih.gov/3433805/">asparagus</a>, can affect urine colour and odour, too.</p> <h2>How much is too much?</h2> <p>Adults should consume <a href="https://www.nhs.uk/live-well/eat-well/food-guidelines-and-food-labels/water-drinks-nutrition/">two-to-three litres per day</a>, of which around 20% comes from food.

A tax on sugary drinks can make us healthier. It’s time for Australia to introduce one

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/peter-breadon-1348098">Peter Breadon</a>, <a href="https://theconversation.com/institutions/grattan-institute-1168">Grattan Institute</a> and <a href="https://theconversation.com/profiles/jessica-geraghty-1530733">Jessica Geraghty</a>, <a href="https://theconversation.com/institutions/grattan-institute-1168"><em>Grattan Institute</em></a></em></p> <p>Sugary drinks cause weight gain and <a href="https://www.nature.com/articles/s41574-021-00627-6">increase the risk</a> of a range of diseases, including diabetes.</p> <p>The <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2792842">evidence shows</a> that well-designed taxes can reduce sugary drink sales, cause people to choose healthier options and get manufacturers to reduce the sugar in their drinks. And although these taxes haven’t been around long, there are already signs that they are making people healthier.</p> <p>It’s time for Australia to catch up to the rest of the world and introduce a tax on sugary drinks. As our new Grattan Institute <a href="https://grattan.edu.au/report/sickly-sweet/">report</a> shows, doing so could mean the average Australian drinks almost 700 grams less sugar each year.</p> <h2>Sugary drinks are making us sick</h2> <p>The share of adults in Australia who are obese has tripled since 1980, from <a href="https://theconversation.com/mapping-australias-collective-weight-gain-7816">10%</a> to more than <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/waist-circumference-and-bmi/latest-release">30%</a>, and diabetes is our <a href="https://www.diabetesaustralia.com.au/about-diabetes/diabetes-in-australia/">fastest-growing</a> chronic condition. The costs for the health system and economy are measured in the billions of dollars each year. But the biggest costs are borne by individuals and their families in the form of illness, suffering and early death.</p> <p>Sugary drinks are a big part of the problem. The more of them we drink, the greater our risk of <a href="https://www.nature.com/articles/s41574-021-00627-6">gaining weight</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2963518/">developing type 2 diabetes</a>, and suffering <a href="https://academic.oup.com/eurpub/article/31/1/122/5896049?login=false">poor oral health</a>.</p> <p>These drinks have no real nutrients, but they do have a lot of sugar. The average Australian consumes <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/apparent-consumption-selected-foodstuffs-australia/latest-release">1.3</a> times the maximum recommended amount of sugar each day. Sugary drinks are responsible for more than one-quarter of our daily sugar intake, more than any other major type of food.</p> <p>You might be shocked by how much sugar you’re drinking. Many 375ml cans of soft drink contain eight to 12 teaspoons of sugar, nearly the entire daily recommended limit for an adult. Many 600ml bottles blow our entire daily sugar budget, and then some.</p> <p>The picture is even worse for disadvantaged Australians, who are more likely to have <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/diabetes/latest-release">diabetes</a> and <a href="https://www.abs.gov.au/statistics/health/health-conditions-and-risks/waist-circumference-and-bmi/latest-release">obesity</a>, and who also consume the most sugary drinks.</p> <h2>Sugary drink taxes work</h2> <p>Fortunately, there’s a proven way to reduce the damage sugary drinks cause.</p> <p>More than <a href="https://ssbtax.worldbank.org/">100 countries</a> have a sugary drinks tax, covering most of the world’s population. <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2792842">Research</a> shows these taxes lead to higher prices and fewer purchases.</p> <p>Some taxes are specifically designed to encourage manufacturers to change their recipes and cut the sugar in their drinks. Under these “tiered taxes”, there is no tax on drinks with a small amount of sugar, but the tax steps up two or three times as the amount of sugar rises. That gives manufacturers a strong incentive to add less sugar, so they reduce their exposure to the tax or avoid paying it altogether.</p> <p>This is the best result from a sugary drinks tax. It means drinks get healthier, while the tax is kept to a minimum.</p> <p>In countries with tiered taxes, manufacturers have slashed the sugar in their drinks. In the United Kingdom, the share of products above the tax threshold <a href="https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1003025">decreased dramatically</a>. In 2015, more than half (52%) of products in the UK were above the tax threshold of 5 grams of sugar per 100ml. Four years later, when the tax was in place, that share had plunged to 15%. The number of products with the most sugar – more than 8 grams per 100ml – declined the most, falling from 38% to just 7%.</p> <p>The Australian drinks market today looks similar to the UK’s before the tax was introduced.</p> <p>Health benefits take longer to appear, but there are already promising signs that the taxes are working. Obesity among primary school-age girls has fallen in <a href="https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1004160">the UK</a> and <a href="https://jamanetwork.com/journals/jamapediatrics/fullarticle/2786784">Mexico</a>.</p> <p>Oral health has also improved, with studies reporting fewer children going to hospital to get their teeth removed in <a href="https://nutrition.bmj.com/content/6/2/243">the UK</a>, and reduced dental decay <a href="https://pubmed.ncbi.nlm.nih.gov/33853058/">in Mexico</a> and <a href="https://www.ajpmonline.org/article/S0749-3797(23)00069-7/abstract">Philadelphia</a>.</p> <p>One <a href="https://www.ajpmonline.org/article/S0749-3797(23)00158-7/fulltext">study from the United States</a> found big reductions in gestational diabetes in cities with a sugary drinks tax.</p> <h2>The tax Australia should introduce</h2> <p>Like successful taxes overseas, Australia should introduce a sugary drink tax that targets drinks with the most sugar:</p> <ul> <li>drinks with 8 grams or more of sugar per 100ml should face a $0.60 per litre tax</li> <li>drinks with 5–8 grams should be taxed at $0.40 per litre</li> <li>drinks with less than 5 grams of sugar should be tax-free.</li> </ul> <p>This means a 250ml Coke, which has nearly 11 grams of sugar per 100ml, would cost $0.15 more. But of course consumers could avoid the tax by choosing a sugar-free soft drink, or a bottle of water.</p> <p>Grattan Institute <a href="https://grattan.edu.au/report/sickly-sweet/">modelling</a> shows that under this tiered tax, Australians would drink about 275 million litres fewer sugary drinks each year, or the volume of 110 Olympic swimming pools.</p> <p>The tax is about health, but government budgets also benefit. If it was introduced today, it would raise about half a billion dollars in the first year.</p> <p>Vested interests such as the beverages industry have fiercely resisted sugary drink taxes around the world, issuing disingenuous warnings about the risks to poor people, the sugar industry and drinks manufacturers.</p> <p>But our new report shows sugary drink taxes have been introduced smoothly overseas, and none of these concerns should hold Australia back.</p> <p>We certainly can’t rely on industry pledges to voluntarily reduce sugar. They have been <a href="https://www.cambridge.org/core/journals/public-health-nutrition/article/trends-in-sugar-content-of-nonalcoholic-beverages-in-australia-between-2015-and-2019-during-the-operation-of-a-voluntary-industry-pledge-to-reduce-sugar-content/EE662DE7552670ED532F6650C9D56939">weak</a> and misleading, and <a href="https://www.theguardian.com/australia-news/2024/apr/10/sugar-increase-in-fanta-and-sprite-prompts-calls-for-new-tax-on-australia-food-and-drinks-industry">failed to stick</a>.</p> <p>It will take many policies and interventions to turn back the tide of obesity and chronic disease in Australia, but a sugary drinks tax should be part of the solution. It’s a policy that works, it’s easy to implement, and most Australians <a href="https://bmjopen.bmj.com/content/9/6/e027962">support it</a>.</p> <p>The federal government should show it’s serious about tackling Australia’s biggest health problems and take this small step towards a healthier future.<!-- Below is The Conversation's page counter tag.

AFP commander resigns after drink driving accident

<p>Former Australian Federal Police commander Danielle Anne Woodward has resigned after she drunkenly crashed her car into a tree following a police function in Canberra.</p> <p>The Olympic medalist pleaded guilty to a drink driving charge in the ACT Magistrates Court after blowing nearly three times the legal limit in November 2023. </p> <p>Woodward had attended an end-of-year function on the night of the accident, and intended to walk home or catch an Uber, but felt unwell after drinking champagne, so she decided to take the short drive back home. </p> <p>However, she crashed into a tree on her way home causing “extensive front-end damage” to her Mercedes-Benz. </p> <p>After getting help from members of the public, she immediately reported the incident to her supervisor and told him she had alcohol in her system.</p> <p>She also reportedly co-operated with lower-ranking officials who attended the scene, with the defence saying that she was "frank in her submission". </p> <p>"She was certainly not belligerent," Woodward's lawyer Michael Kukulies-Smith told the court. </p> <p>She was then arrested and taken to the police station for a breath analysis, which came back with a reading of 0.148. </p> <p>A police statement of facts also said that officers found Woodward with a flushed face and sleepy, watery eyes.</p> <p>“Police could smell a strong odour of intoxicating liquor emanating from [Woodward] and formed the opinion that [she] was well under the influence,” the statement of facts read. </p> <p>The court also heard that Woodward had been experiencing a "high level" of stress from her job, so had "at times resorted to alcohol, in a way she has been able to control."</p> <p>"The offending conduct is not only out of character … [but] her actions are usually the complete opposite. They're usually designed to benefit and protect the community," prosecutor Samuel Carmichael said.</p> <p>Woodward's lawyer asked Chief Magistrate Lorraine Walker to record a non-conviction, as this was a "one off" offence, and the media coverage of the accident had already caused her "an unusual degree of reputational damage", which has impacted her mental health and career. </p> <p>While Magistrate Walker agreed to a non-conviction, she said that a general deterrence still needed to be served, with Woodward disqualified from driving for six months, taking into account a 90-day immediate suspension notice that was issued after the crash.</p> <p>The Chief Magistrate told the court: "What ultimately influences me … is Ms Woodward is a woman suffering from ill health.</p> <p>"It is often people of good standing in this community … who find themselves before the court for this type of offence."</p> <p>She also said that Woodward had shown “obvious and palpable” remorse, and was not someone who would ordinarily demonstrate “this level of stupidity”. </p> <p>Woodward was a highly decorated police officer who worked for the AFP for almost four decades. She became a commander in 2022 and received a Medal of the Order of Australia (OAM) in 2002.</p> <p>In 2020 she was awarded the Australian Police Medal in the Australia Day honours. </p> <p>Prior to her role in the AFP, she was a a triple Olympian in slalom canoeing and won a silver medal at the 1992 Barcelona Olympics. </p> <p><em>Image: ABC News</em></p>

REVIEW: Super-intelligent, dog-detecting robot lawn mower

<p>I was recently invited to an onsite demonstration of a brand new line of lawn mowers that were pitched as being not just a lawn mower, but a furry-friend dodging, grass-grooming marvel of modern technology.</p> <p>According to the specs, the <a href="https://au.worx.com/vision-technology/" target="_blank" rel="noopener">WORX LANDROID® Vision</a> is the world’s first advanced AI, "unbox &amp; mow" robot lawn mower. "No wire. No satellite. No beacons. No time between unboxing and mowing."</p> <p>Using a combination of HRD camera, the latest AI smarts and a deeply trained neural network to identify grass to mow and obstacles to avoid, it features the innovative "Cut-to-Edge" function, multi-zone management and adaptive auto-scheduling. Plus an<span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;"> optional LED headlight safe night-mowing (apparently, unlike conventional robots, Vision sees nocturnal animals and stays away from them).</span></p> <p>But the real test for me was always going to be: how would something like the Vision get along with my dog, Rosie? I was offered the chance to try out one of the mowers for a few weeks, and so I jumped at it.</p> <p>But let's talk about Rosie for a moment. Now, this little ball of fur thinks she's the queen of the backyard. She zooms around like a tiny tornado, and honestly I think she believes the grass is her personal chew toy. So, when I introduced the LANDROID into the mix, I was half expecting chaos and half hoping for a miracle.</p> <p>Lo and behold, this mower is not just a lawn whisperer; it's a puppy ninja. The WORX LANDROID has some sort of superpower in its sensors, allowing it to detect my pup's presence and skilfully manoeuvre around her. It was like watching a graceful dance between technology and canine curiosity.</p> <p>For the duration of the test, Rosie basically appointed herself as the official supervisor of lawn maintenance, proudly watching from a safe distance (and sometimes not so safe) as the LANDROID worked its magic.</p> <p>But let's not forget about the real star of the show: the lawn itself. The LANDROID doesn't just dodge around obstacles; it trims with precision, leaving my yard looking like a freshly coiffed celebrity. It's like having a personal stylist for my grass – one that never sleeps. </p> <p>And the best part? I get to sit back, relax and sip my lemonade while the LANDROID does all the heavy lifting (or should I say, mowing). It's like having a reliable little garden gnome, except this one runs on electricity and has impeccable dodging skills.</p> <p>So if you want a lawn mower that's not only efficient but also entertaining, look no further than the <a href="https://au.worx.com/vision-technology/" target="_blank" rel="noopener">WORX LANDROID Vision</a>. It's the perfect blend of technology, pet sensitivity and grass-grooming prowess. Plus, it's the only mower I know that can outmanoeuvre a puppy – and that is definitely something to bark about.</p> <p><em>Images: Alex Cracknell</em></p>
