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.

Alan Jones once seemed unassailable. What ended it was a peculiarly Sydney story of media, politics and power

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/denis-muller-1865">Denis Muller</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p>For decades it seemed Alan Jones was unassailable.</p> <p>A finding against him of professional misconduct by the Australian Broadcasting Authority (2000); a <a href="https://www.smh.com.au/entertainment/tv-and-radio/tribunal-upholds-that-jones-incited-hatred-20121002-26x8h.html">finding</a> that he incited hatred, serious contempt and severe ridicule of Lebanese Muslims (2009); propositions of violence against two women prime ministers (<a href="https://www.abc.net.au/news/2011-10-20/alan-jones-says-gillard-remark-best-left-unsaid/3579658">2011</a> and <a href="https://www.abc.net.au/news/2020-05-21/alan-jones-breached-rules-in-jacinda-ardern-comment/12271476">2019</a>); verdicts against him and his employer amounting to millions of dollars in defamation actions (most notably <a href="https://www.abc.net.au/news/2018-09-12/alan-jones-defamed-wagners-court-decision-brisbane-qld/10230384">one for $3.75 million</a> in 2018): none of these ended his career.</p> <p>Quite the reverse. Only weeks after the Australian Broadcasting Authority found in its “cash for comments” inquiry that Jones and others had misled their listeners by presenting paid endorsements as editorial opinion, he was hosting an event for then prime minister John Howard.</p> <p>Howard was to become a fixture on the Jones program throughout the 11 years of his prime ministership.</p> <p>The day after the Australian Communications and Media Authority found Jones was likely to have encouraged violence and vilification of Australians of Lebanese and Middle Eastern background, Howard <a href="https://www.theage.com.au/national/jones-wins-friends-in-high-places-20070412-ge4n4f.html">described him</a> as “an outstanding broadcaster”. “I don’t think he’s a person who encourages prejudice in the Australian community, not for one moment, but he is a person who articulates what a lot of people think.”</p> <p>By 2001, Jones had become a kind of on-air policy-maker for the New South Wales government. In November that year, he dined with the then Labor premier, Bob Carr. They discussed a range of government policies, particularly policing. At that time, Jones was a relentless critic of the NSW police.</p> <p>The following week, <a href="https://www.abc.net.au/news/2012-10-01/newton-alan-jones/4288824">Carr dispatched</a> his police minister-designate, Michael Costa, to Jones’s home to discuss policing policy.</p> <p>In 2011 he said Julia Gillard, then Australia’s prime minister, should be taken out to sea and dumped in a chaff bag. In August 2019 he said Scott Morrison, who was then Australia’s prime minister, should “shove a sock” down the throat of his New Zealand counterpart Jacinda Ardern.</p> <p>He was an outspoken climate-change denier, and these grotesqueries were part of his campaign against political recognition of this reality.</p> <figure><iframe src="https://www.youtube.com/embed/Od6I1YbrBoM?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Jones’s power, which made him so apparently untouchable, came from his weaponising of the microphone for conservative political ends in ways that resonated with his vast and rusted-on audience of largely working-class older people across Sydney’s sprawling western suburbs.</p> <p>These suburbs contain many marginal state and federal electorates where the fates of governments can be decided. Their populations provide fertile ground for seeding by right-wing radio shock jocks, of whom Jones and his rival John Laws were pre-eminent examples.</p> <p>In Australia, this is a peculiarly Sydney phenomenon. It is not seen to the same degree in any other capital city, even though they too have large areas of socioeconomic disadvantage like western Sydney.</p> <p>Why that should be so is a complex question, but there are aspects of Sydney life that mark it out as different. It is really two cities. One is the largely prosperous and scenically dazzling east and north. The other, much larger, consists of dreary tracts of increasingly crowded housing stretching for many kilometres to the west and southwest.</p> <p>In Sydney argot, the inhabitants of these respective worlds are called “silvertails” and “fibros”, the latter referring to the cladding of the homes that proliferated in western Sydney between and after the two world wars.</p> <p>This two-cities effect makes the gap between the “haves” and the “have-nots” highly visible in a way that has no parallel in other Australian capitals. It engenders deep-seated grievance and cynicism, which the likes of Jones, who lives in a multimillion-dollar apartment on Circular Quay, have relentlessly exploited.</p> <p>Jones coined the term “Struggle Street” to encapsulate the hardships of his listeners’ lives.</p> <p>To these powerless people, Jones and Laws gave a voice, and as their audiences grew, prime ministers and premiers courted and feared them.</p> <p>In the end, Jones’s impregnability was breached by not the power elite turning on one of their own, but by the journalism of a redoubtably tenacious Sydney Morning Herald investigative reporter, Kate McClymont.</p> <p>In December 2023, <a href="https://www.smh.com.au/national/he-d-go-the-grope-alan-jones-accused-of-indecently-assaulting-young-men-20231205-p5epai.html">she claimed</a> Jones had used his position of power, first as a teacher and later as the country’s top-rating radio broadcaster, to allegedly prey on a number of young men.</p> <p>In response to McClymont’s work, the NSW police set up Strike Force Bonnefin, run by the State Crime Command’s Child Abuse Squad, to conduct an investigation into Jones.</p> <figure><iframe src="https://www.youtube.com/embed/0ExkpCtfmA8?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>On November 18 2024, Jones was arrested at his Circular Quay home and charged initially with 24 sexual offences against eight males. The following day, two <a href="https://www.abc.net.au/news/2024-11-19/alan-jones-charged-with-additional-offences-nsw-police/104617680">additional charges</a> were laid involving a ninth male.</p> <p>Through his lawyers, Jones has denied the charges and was bailed to appear in Sydney’s Downing Centre Local Court on December 18. He <a href="https://www.smh.com.au/national/alan-jones-arrested-over-allegations-he-indecently-assaulted-young-men-20241118-p5krdu.html">was ordered</a> to surrender his passport and not to contact or harass the alleged victims.</p> <p>The charges relate to offences alleged to have been committed by Jones between 2001 and 2019, the youngest alleged victim being 17 at the time.</p> <p>Those dates coincide almost exactly with Jones’s most influential years, from 2002 to 2020.</p> <p>McClymont <a href="https://www.smh.com.au/national/a-stunning-development-kate-mcclymont-on-alan-jones-arrest-and-what-s-next-20241118-p5krln.html">has spoken</a> about the reluctance of some of her interviewees to speak, for fear of what Jones might do: "People were too afraid to take on Alan Jones.

"You made me enjoy the game": Federer's emotional retirement letter to Nadal

<p>Roger Federer has penned an emotional tribute to Rafael Nadal ahead of his retirement, reflecting on their stellar careers together. </p> <p>Nadal’s career officially came to an end when Spain was defeated 2-1 by the Netherlands in the Davis Cup quarter-final in Malaga on Wednesday morning, with Nadal in tears as he stepped onto the court for the final time. </p> <p>Thousands of tributes poured in for Nadal as his retirement officially began, but Federer's tribute quickly went viral for his emotional words.</p> <p>“As you get ready to graduate from tennis, I’ve got a few things to share before I maybe get emotional,” Federer said. </p> <p>“Let’s start with the obvious: you beat me - a lot. More than I managed to beat you. You challenged me in ways no one else could. On clay, it felt like I was stepping into your backyard, and you made me work harder than I ever thought I could just to hold my ground."</p> <p>“You made me reimagine my game - even going so far as to change the size of my racquet head, hoping for any edge. I’m not a very superstitious person, but you took it to the next level. Your whole process. All those rituals."</p> <p>“Assembling your water bottles like toy soldiers in formation, fixing your hair, adjusting your underwear … All of it with the highest intensity. Secretly, I kind of loved the whole thing. Because it was so unique - it was so you."</p> <p>“And you know what, Rafa, you made me enjoy the game even more. OK, maybe not at first. After the 2004 Australian Open, I achieved the No. 1 ranking for the first time. I thought I was on top of the world. And I was - until two months later, when you walked on the court in Miami in your red sleeveless shirt, showing off those biceps, and you beat me convincingly."</p> <p>"All that buzz I’d been hearing about you - about this amazing young player from Mallorca, a generational talent, probably going to win a major someday - it wasn’t just hype."</p> <p>“We were both at the start of our journey and it’s one we ended up taking together. Twenty years later, Rafa, I have to say: What an incredible run you’ve had. Including 14 French Opens - historic! You made Spain proud … you made the whole tennis world proud."</p> <p>“And then there was London – the Laver Cup in 2022. My final match. It meant everything to me that you were there by my side – not as my rival but as my doubles partner."</p> <p>“Sharing the court with you that night, and sharing those tears, will forever be one of the most special moments of my career.”</p> <p>Federer signed off the 585-word tribute from “your fan Roger”.</p> <p><em>Image credits: ANDY RAIN/EPA-EFE/Shutterstock Editorial </em></p>

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/nikki-anne-wilson-342631">Nikki-Anne Wilson</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a></em></p> <p>The way people living with dementia <a href="https://www.alzheimers.org.uk/about-dementia/symptoms-and-diagnosis/how-dementia-changes-perception">experience the world</a> can change as the disease progresses. Their sense of reality or place in time can become distorted, which can cause <a href="https://www.alzheimers.org.uk/about-dementia/symptoms-and-diagnosis/symptoms/restlessness">agitation and distress</a>.</p> <p>One of the best ways to support people experiencing changes in perception and behaviour is to <a href="https://www.dementia.org.au/professionals/designing-dementia-friendly-care-environments">manage their environment</a>. This can have profound benefits including <a href="https://www.agedcarequality.gov.au/resource-library/reducing-use-sedatives-aged-care-video">reducing the need for sedatives</a>.</p> <p>One such strategy is the use of dolls as comfort aids.</p> <h2>What is ‘doll therapy’?</h2> <p>More appropriately referred to as “<a href="https://www.dementia.com.au/resource-hub/the-use-of-dolls-in-dementia-care">child representation</a>”, lifelike dolls (also known as empathy dolls) can provide comfort for some people with dementia.</p> <p>Memories from the <a href="https://www.alzheimers.org.uk/about-dementia/symptoms-and-diagnosis/symptoms/memory-loss#:%7E:text=Older%20memories%20%E2%80%93%20which%20have%20been,detailed%20memories%20from%20earlier%20life.">distant past</a> are often more salient than more recent events in dementia. This means that past experiences of parenthood and caring for young children may feel more “real” to a person with dementia than where they are now.</p> <p><a href="https://www.alzheimers.org.uk/about-dementia/symptoms-and-diagnosis/hallucinations#:%7E:text=Visual%20hallucinations%20are%20more%20common,hallucinating%20and%20how%20others%20respond.">Hallucinations or delusions</a> may also occur, where a person hears a baby crying or fears they have lost their baby.</p> <p>Providing a doll can be a tangible way of reducing distress without invalidating the experience of the person with dementia.</p> <h2>Some people believe the doll is real</h2> <p>A recent case involving <a href="https://www.theguardian.com/australia-news/2024/nov/06/deplorable-nurse-slammed-therapy-doll-dementia-patient-believed-was-real-baby-on-table-nsw-tribunal-hears">an aged care nurse mistreating a dementia patient’s therapy doll</a> highlights the importance of appropriate training and support for care workers in this area.</p> <p>For those who do become attached to a therapeutic doll, they will treat the doll as a real baby needing care and may therefore have a profound emotional response if the doll is mishandled.</p> <p>It’s important to be guided by the person with dementia and only act as if it’s a real baby if the person themselves believes that is the case.</p> <h2>What does the evidence say about their use?</h2> <p>Evidence shows the use of empathy dolls may help <a href="https://www.sciencedirect.com/science/article/pii/S0197457223002677">reduce agitation and anxiety</a> and <a href="https://www.mdpi.com/2039-4403/14/4/200">improve overall quality of life</a> in people living with dementia.</p> <p>Child representation therapy falls under the banner of <a href="https://www.sciencedirect.com/science/article/pii/S0149763423004761">non-pharmacological approaches to dementia care</a>.

It has been suggested that child representation therapy “infantilises” people living with dementia and may increase negative stigma.</p> <p>Further, the attachment may become so strong that the person with dementia will <a href="https://www.dementiauk.org/information-and-support/living-with-dementia/doll-therapy/">become upset if someone else picks the doll up</a>. This may create some difficulties in the presence of grandchildren or when cleaning the doll.</p> <p>The introduction of child representation therapy may also require additional staff training and time. Non-pharmacological interventions such as child representation, however, have been shown to be <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10180718/">cost-effective</a>.</p> <h2>Could robots be the future?</h2> <p>The use of more <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8247474/#:%7E:text=Therefore%2C%20an%20interactive%20baby%20robot,mental%20support%20for%20older%20adults.">interactive empathy dolls</a> and <a href="https://journals.sagepub.com/doi/full/10.1177/14713012231155985">pet-like robots</a> is also gaining popularity.</p> <p>While robots have been shown to be <a href="https://www.sciencedirect.com/science/article/pii/S1568163722000757">feasible and acceptable in dementia care</a>, there remains some contention about their benefits.</p> <p>While some studies have shown <a href="https://academic.oup.com/innovateage/article/5/2/igab013/6249558?login=false">positive outcomes</a>, including reduced agitation, others show <a href="https://www.sciencedirect.com/science/article/pii/S1568163722000757">no improvement</a> in cognition, behaviour or quality of life among people with dementia.</p> <p>Advances in artificial intelligence are also being used to help support people living with dementia and <a href="https://journals.sagepub.com/doi/full/10.1177/1471301221998888">inform</a> the community.</p> <p><a href="https://feel-lab.org/research_projects/ai-viv-and-friends/">Viv and Friends</a>, for example, are AI companions who appear on a screen and can interact with the person with dementia in real time. The AI character Viv has dementia and was co-created with women living with dementia using verbatim scripts of their words, insights and experiences. While Viv can share her experience of living with dementia, she can also be programmed to talk about common interests, such as gardening.</p> <p>These companions are currently being trialled in some residential aged care facilities and to help educate people on the lived experience of dementia.</p> <h2>How should you respond to your loved one’s empathy doll?</h2> <p>While child representation can be a useful adjunct in dementia care, it requires sensitivity and appropriate consideration of the person’s needs.</p> <p>People living with dementia <a href="https://pubmed.ncbi.nlm.nih.gov/38325063/">may not perceive the social world the same way</a> as a person without dementia.

What causes the itch in mozzie bites? And why do some people get such a bad reaction?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/cameron-webb-6736">Cameron Webb</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Are you one of these people who loathes spending time outdoors at dusk as the weather warms and mosquitoes start biting?</p> <p>Female mosquitoes <a href="https://www.annualreviews.org/content/journals/10.1146/annurev-ento-120811-153618">need blood</a> to develop their eggs. Even though they take a tiny amount of our blood, they can leave us with itchy red lumps that can last days. And sometimes something worse.</p> <p>So why does our body react and itch after being bitten by a mosquito? And why are some people more affected than others?</p> <h2>What happens when a mosquito bites?</h2> <p>Mosquitoes are attracted to warm blooded animals, including us. They’re attracted to the <a href="https://www.cambridge.org/core/journals/bulletin-of-entomological-research/article/abs/role-of-carbon-dioxide-in-hostfinding-by-mosquitoes-diptera-culicidae-a-review/2506B86EF63852B2D02EC3FCEE1E3B8B">carbon dioxide</a> we exhale, our body temperatures and, most importantly, <a href="https://www.abc.net.au/news/2024-11-08/mosquitoes-climate-change-skin/104548122">the smell of our skin</a>.</p> <p>The <a href="https://www.cell.com/trends/parasitology/abstract/S1471-4922(21)00237-3">chemical cocktail</a> of odours from bacteria and sweat on our skin <a href="https://www.cell.com/current-biology/fulltext/S0960-9822(23)00532-8">sends out a signal</a> to hungry mosquitoes.</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S2667114X21000522">Some people’s</a> skin smells more appealing to mosquitoes, and they’re more likely to be bitten than others.</p> <p>Once the mosquito has made its way to your skin, things get a little gross.</p> <p>The mosquito pierces your skin with their “proboscis”, their feeding mouth part. But the proboscis isn’t a single, straight, needle-like tube. There are multiple tubes, <a href="https://www.npr.org/sections/health-shots/2016/06/07/480653821/watch-mosquitoes-use-6-needles-to-suck-your-blood">some designed</a> for sucking and some for spitting.</p> <p>Once their mouth parts have been inserted into your skin, the mosquito will inject some saliva. This contains a mix of chemicals that gets the blood flowing better.</p> <p>There has even been a suggestion that future medicines could be inspired by the <a href="https://www.sydney.edu.au/news-opinion/news/2018/03/29/mosquito-saliva-vital-to-the-discovery-of-future-drugs.html">anti-blood clotting properties</a> of mosquito saliva.</p> <p>It’s not the stabbing of our skin by the mosquito’s mouth parts that hurts, it’s the mozzie spit our bodies don’t like.</p> <h2>Are some people allergic to mosquito spit?</h2> <p>Once a mosquito has injected their saliva into our skin, a variety of reactions can follow. For the lucky few, nothing much happens at all.</p> <p>For most people, and irrespective of the type of mosquito biting, <a href="https://www.frontiersin.org/journals/immunology/articles/10.3389/fimmu.2022.1024559/full">there is some kind of reaction</a>. Typically there is <a href="https://www.sciencedirect.com/science/article/abs/pii/S0161589023002304?via%3Dihub">redness and swelling of the skin</a> that appears within a few hours, but often more quickly, after just a few minutes.</p> <p>Occasionally, the reaction can cause pain or discomfort. Then comes the <a href="https://www.abc.net.au/news/health/2023-01-20/mosquito-bites-itchy-calamine-heat-ice-antihistamine-toothpaste/101652608">itchiness</a>.</p> <p>Some people do suffer severe reactions to mosquito bites. It’s a condition often referred to as “<a href="https://www.webmd.com/allergies/what-is-skeeter-syndrome">skeeter syndrome</a>” and is an allergic reaction caused by the protein in the mosquito’s saliva. This can cause large areas of swelling, blistering and fever.</p> <p>The chemistry of mosquito spit hasn’t really been well studied. But it has been shown that, for those who do suffer allergic reactions to their bites, the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0091674904022183">reactions may differ</a> depending on the type of mosquito biting.</p> <p>We all probably get more tolerant of mosquito bites as we get older. Young children are certainly more likely to suffer more following mosquito bites. But as we get older, the reactions are less severe and may pass quickly without too much notice.</p> <h2>How best to treat the bites?</h2> <p>Research into treating bites <a href="https://linkinghub.elsevier.com/retrieve/pii/S0161589023002304">has yet to provide</a> a single easy solution.</p> <p>There are many <a href="https://www.healthline.com/health/outdoor-health/home-remedies-for-mosquito-bites">myths and home remedies</a> about what works. But there is little scientific evidence supporting their use.</p> <p>The best way to treat mosquito bites is by applying a cold pack to reduce swelling and to keep the skin clean to avoid any secondary infections. Antiseptic creams and lotions may also help.</p> <p>There is some evidence that <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10309056/">heat may alleviate</a> some of the discomfort.</p> <p>It’s particularly tough to keep young children from scratching at the bite and breaking the skin. This can form a nasty scab that may end up being worse than the bite itself.</p> <p>Applying an anti-itch cream may help. If the reactions are severe, <a href="https://www.healthdirect.gov.au/insect-bites-and-stings">antihistamine medications</a> may be required.</p> <h2>To save the scratching, stop the bites</h2> <p>Of course, it’s better not to be bitten by mosquitoes in the first place. Topical <a href="https://theconversation.com/insect-repellents-work-but-there-are-other-ways-to-beat-mosquitoes-without-getting-sticky-171805">insect repellents</a> are a safe, effective and affordable way to reduce mosquito bites.</p> <p>Covering up with loose fitted long sleeved shirts, long pants and covered shoes also provides a physical barrier.</p> <p><a href="https://theconversation.com/are-mosquito-coils-good-or-bad-for-our-health-88548">Mosquito coils and other devices</a> can also assist, but should not be entirely relied on to stop bites.</p> <p>There’s another important reason to avoid mosquito bites: millions of people around the world suffer from mosquito-borne diseases. More than <a href="https://www.who.int/news-room/fact-sheets/detail/malaria">half a million people die</a> from malaria each year.</p> <p>In Australia, <a href="https://journals.plos.org/plospathogens/article?id=10.1371/journal.ppat.1005070">Ross River virus</a> infects more than 5,000 people every year.

Readers response: What was the worst hotel experience you had?

<p>We asked our readers to share their stories of the worst hotel experience that have endured while on holiday, and the response was overwhelming. Here's what they said. </p> <p><strong>Deedee Cullum</strong> - At a 5 star in Beijing. Arrived from the airport after 1am. Let into the room to find it occupied with someone having a bath. Instead of changing our room we waited in the lobby for 1 and 1/2 hours while they changed to the correct room and cleaned ours. The wet towels were neatly folded on the towel rack and the used soap was on the basin. When I turned the bedside light on I got a shock. To be fair management were most apologetic and gave us free dining in their top restaurant for the 4 days we were there. It was a few years ago but never forgotten.</p> <p><strong>Bruce Hopkins</strong> - I stopped at a Hotel in Hobart, arrived in the afternoon, checked out the next day, the whole time I stopped there, I never saw anyone on reception or any staff at all. Creepiest hotel I stayed in.</p> <p><strong>Carol Henwood</strong> - When we went to have a shower, and the towels disintegrated! The shower had black mould in all the corners. The carpet was so sticky, we kept our shoes on.  We slept on top of the bed as the sheets were crumpled and smelly. What a night.</p> <p><strong>Sheila Kell </strong>- When my eldest son was about 2 years old we took a holiday to Shute Harbour in QLD and in middle of night we heard lots of scratching so turned on light and sat up in bed and there were hundreds of field mice crawling up walls and back of bed. They apparently were having a plague, but we dressed and left. Couldn't sleep in that motel.</p> <p><strong>Christine Warner</strong> - A country pub only option one night. Our room has no lock on the door, and there were gaps in the floorboards so we could see straight down to the bar where it was very noisy. We had already been warned of people breaking in to hotel and motel rooms in that region, so we slept in the car and returned to the room in the morning for a shower.</p> <p><strong>Helen Wilson</strong> - In Singapore, they gave us a “free” breakfast while someone rummaged through our belongings and took stuff.</p> <p><em>Image credits: Shutterstock </em></p> <p> </p>

What’s the difference between MSG and table salt? A chemist explains

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a></em></p> <p>It’s dinner time. You’ve worked hard to prepare a nutritious and tasty meal. But after taking your first bite you feel something is missing. Perhaps you should have added more salt? Pepper? Or maybe even something more exotic like monosodium glutamate, better known as MSG?</p> <p>There are many <a href="https://theconversation.com/explainer-what-are-e-numbers-and-should-you-avoid-them-in-your-diet-43908">food additives</a> used in both home cooking and commercial products. These ingredients improve the flavour, smell, texture, appearance and longevity of foods.</p> <p>Salt and MSG are two well-known food additives. Both contain sodium, but there are plenty of differences which you can use to your benefit.</p> <h2>What is a salt?</h2> <p>Salts are made of positively and negatively charged components called ions. Salts generally dissolve in water, and are brittle. The names of salts often feature a metal (positively charged) followed by a non-metal (negatively charged).</p> <p>The common kitchen ingredient we call “salt” is just one type of salt. To distinguish it from all other salts, we should more specifically refer to it as “table salt”. Chemically, it’s sodium chloride.</p> <h2>Sodium chloride</h2> <p>After the quick chemistry lesson above, we can see that table salt, sodium chloride, contains a positively charged sodium and a negatively charged chlorine.</p> <p>These charged components are arranged in crystals of salt in a regular repeating pattern. Each sodium ion is surrounded by six chloride ions and each chloride ion is surrounded by six sodium ions. This arrangement gives the crystal a “cubic” form. If you look closely at salt, you may see cube-shaped crystals.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=600&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=600&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=600&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=754&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=754&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/617802/original/file-20240906-16-gk38c9.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=754&amp;fit=crop&amp;dpr=3 2262w" alt="" /></a><figcaption><span class="caption">The chemical structure of table salt forms a cube of sodium and chloride ions.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-vector/sodium-chloride-nacl-structure-ionic-crystal-2417242373">Sandip Neogi/Shutterstock</a></span></figcaption></figure> <p>Sodium chloride is very abundant. It is found <a href="https://theconversation.com/i-have-always-wondered-why-is-the-sea-salty-83489">dissolved in Earth’s oceans</a>. Mineral deposits of salt, known as halite or rock salt, formed from the evaporation and crystallisation of ancient seas.</p> <p>Depending on the source, the salt may contain many other trace minerals that can even add colour to it, such as the pink-coloured Himalayan salt from Pakistan. Salt can also be fortified with <a href="https://www.who.int/publications/i/item/9789240053717">sodium iodide</a> as a public health measure.</p> <p>Describing the taste of salt is quite difficult without using the word “salty”. It’s a very common food additive, as it is so abundant and versatile. It is an essential ingredient for many traditional food preservation techniques for meats (pork and fish), vegetables (kimchi, sauerkraut and pickles), and dairy (cheese and butter).</p> <p>Salt is considered a universal flavouring agent. It can mask bitter flavours and bring out sweet, sour and <a href="https://theconversation.com/the-asian-roots-of-umami-the-fifth-taste-central-to-thanksgiving-fare-50699">umami</a> (savoury) ones.</p> <p>Despite popular depictions of <a href="https://theconversation.com/that-neat-and-tidy-map-of-tastes-on-the-tongue-you-learned-in-school-is-all-wrong-44217">taste maps</a>, there is no one place on the tongue where we taste salt. Other sodium salts can also give a “salty” taste, but the effect declines (and can even turn to bitter) with negatively charged components other than chloride.</p> <h2>MSG or monosodium glutamate</h2> <p>Monosodium glutamate is also a salt. The glutamate is the negatively charged form of glutamic acid, an amino acid that is found in nature as a building block of proteins.</p> <p>MSG, and more generally glutamates, are found in a wide range of foods including tomatoes, Parmesan cheese, soy sauce, dried seaweeds, Worcestershire sauce and protein-rich foods. All of these foods impart umami flavours, which are described as savoury or meaty.</p> <p>Commercial MSG is not extracted from the environment but produced by bacterial fermentation. Glucose is converted to glutamic acid, which is further processed by adding sodium hydroxide to form MSG (and water).</p> <p>MSG is sold as crystals, but they have a long, prismatic shape rather than the cubic form of sodium chloride. It’s worth tasting a few crystals of MSG directly to experience the native taste of umami.</p> <p>Despite decades of bad press and concern, <a href="https://theconversation.com/msg-is-back-is-the-idea-its-bad-for-us-just-a-myth-or-food-science-237871">MSG is considered safe</a> to consume in the concentrations typically found in or added to foods.</p> <p>Table salt and MSG both contain sodium, but at different percentages of the total weight: table salt has around 40% sodium, versus just 14% in MSG. You are also more likely to be routinely adding table salt to your food rather than MSG.</p> <p>Eating too much sodium is well known to be unhealthy. <a href="https://theconversation.com/this-salt-alternative-could-help-reduce-blood-pressure-so-why-are-so-few-people-using-it-221409">Potassium-enriched substitutes</a> have been suggested for a range of health benefits.</p> <h2>A flavour enhancer</h2> <p>The flavour of MSG can be elevated further by combining it with other food additives, known as sodium ribonucleotides.</p> <p>Japanese and Korean cooks figured this secret out long before chemists, as boiling dried fish and seaweed produces foundation stocks (dashi) containing a mix of naturally sourced glutamates and ribonucleotides.</p> <p>Ribonucleotides are classified as “generally considered as safe” by <a href="https://www.cfsanappsexternal.fda.gov/scripts/fdcc/index.cfm?set=FoodSubstances&amp;id=DISODIUMINOSINATE&amp;sort=Sortterm_ID&amp;order=ASC&amp;startrow=1&amp;type=basic&amp;search=disodium">food standards authorities</a>. Humans consume many grams of the natural equivalent in their diets.</p> <p>What can be more problematic are the carbohydrates- and fat-rich foods that have their flavours enhanced, which can potentially lead us to eat excessive calories.</p> <p>The combination of MSG and ribonucleotides produces a more-ish sensation. Next time you see a bag of potato chips or instant noodles, have a quick look to see if it contains both MSG (E621) and a ribonucleotide source (E627–E635).</p> <p>I personally keep a jar of MSG in my kitchen. A little goes a long way to elevate a soup, stew or sauce that isn’t quite tasting the way you want it to, but without adding too much extra sodium.<!-- Below is The Conversation's page counter tag.

Readers response: What’s the best advice you’ve received on staying healthy as you age?

<p>We asked our readers what the best advice they’ve received on staying healthy as you age is, and the response was overwhelming. Here's what they said. </p> <p><strong>Fred Pilcher </strong>- Don't smoke. That's the most important advice you're likely to get. If you do smoke, quit now. Today. I've lost parents and friends to lung cancer and emphysema - both terrible ways to go. (I say this as a former two pack a day addict.)</p> <p><strong>Kate Caddey</strong> - Stay as fit as you can. Walk, do the stretch, balance and dance offerings. Travel the slightly harder way with ups and downs included. Stay curious about people you meet and about everything in general. Never stop learning.</p> <p><strong>Marie Jones</strong> - Keep laughing.</p> <p><strong>Gloria Hickey</strong> - Keep active, but wish I had been told to have my B12 added to yearly blood work too. </p> <p><strong>Peter Connolly</strong> - Best advice I got was "Whatever you do, go out with a bang. There is absolutely no point in lying in bed in a hospital, dying of nothing!"</p> <p><strong>Terry Dolman</strong> - Enjoy being happy. It takes more energy to be grumpy than smile. Plus, a good Friend in Vietnam now said "don't carry the past plus a drink of whisky a day." </p> <p><strong>Heather Dixon</strong> - Keep busy.</p> <p><strong>Lydia Poli </strong>- Enjoy the ride while you can!</p> <p><strong>Marlene Cochrane</strong> - Don't stop moving. Both physically and mentally.</p> <p><strong>Karen Ambrose</strong> - Keep dancing!</p> <p><em>Image credits: Shutterstock </em></p>

"Shame on you all": Lydia Thorpe hits back after Senate censure

<p>Independent Senator Lidia Thorpe has spoken out after the Senate voted to censure her over a protest she staged during King Charles' Australian visit.</p> <p>During the monarch's visit to Canberra, Thorpe started yelling from the back of the room following King Charles' speech to a room of political and community leaders at Parliament House's Great Hall. </p> <p>“You committed genocide against our people. Give us our land back. Give us what you stole from us, our bones, our skulls, our babies, our people, you destroyed our land,” Thorpe said during her outburst.</p> <p>“We want a treaty in this country. This is not your land. You are not my King, you are not our King. F*** the colony.”</p> <p>The outburst prompted a vote from the Senate to censure Thorpe - meaning to formally share an expression of the Senate's disapproval - as she responded to the decision on Monday saying, the motion was "a clear articulation of the racism that I continually have to deal with in my workplace."</p> <p>Thorpe said the vote was, "A time where you see Labor and the Liberal party come together to shut down a Blak voice — that’s been happening in this country for over 200 years."</p> <p>The Senate passed a motion 46 votes to 12 to censure her over her actions, as Thorpe entered the Senate chamber after the vote and yelled: "Shame on you all".</p> <p>"If (the king) comes back in, I'll do it again."</p> <p>Thorpe was not present for the vote due to a flight delay, although she said she had contacted Labor minister Don Farrell to ask him to delay the vote but claimed she was "denied my right to be in that chamber whilst everybody else voted to shut me down".</p> <p>Thorpe later told reporters she "did not give a damn" about being censured and tore up a piece of paper with the motion on it.</p> <p>Thorpe said in a statement before the vote took place that that motion showed "where the major parties' priorities lie".</p> <p>"They don't stand with First Peoples in this country. They stand against justice for our people, preferring instead to defend a foreign king, rather than listen to the truth," she said.</p> <p>"In no way do I regret protesting the King ... it is time this country reckons with its history, and puts a stop to the continuing genocide on First Peoples."</p> <p>Image credits: MICK TSIKAS/EPA-EFE/Shutterstock Editorial </p>

These 12 things can reduce your dementia risk – but many Australians don’t know them all

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/joyce-siette-1377445">Joyce Siette</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> and <a href="https://theconversation.com/profiles/laura-dodds-1378067">Laura Dodds</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a></em></p> <p>Dementia is a <a href="https://www.abs.gov.au/statistics/health/causes-death/provisional-mortality-statistics/jan-may-2022">leading</a> cause of death in Australia.</p> <p>Although dementia mainly affects older people, it is an avoidable part of ageing. In fact, we all have the power to reduce our risk of developing dementia, no matter your age.</p> <p>Research shows your risk of developing dementia could be <a href="https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext">reduced by up to 40%</a> (and even higher if you live in a <a href="https://www.thelancet.com/journals/langlo/article/PIIS2214-109X(19)30074-9/fulltext">low or middle-income country</a>) by addressing lifestyle factors such as healthy diet, exercise and alcohol consumption.</p> <p>But the first step to reducing population-wide dementia risk is to understand how well people understand the risk factors and the barriers they may face to making lifestyle changes.</p> <p>Our new <a href="https://www.mdpi.com/2673-9259/2/4/21/htm">paper</a>, published this week in the <a href="https://www.mdpi.com/2673-9259/2/4/21/htm">Journal of Ageing and Longevity</a>, found most older people are aware that dementia is a modifiable condition and that they have the power to change their dementia risk.</p> <p>We also found the key barrier to making brain healthy lifestyle choices was a lack of knowledge, which suggests a public awareness campaign is urgently needed.</p> <h2>What we did</h2> <p>We began by <a href="https://www.mdpi.com/2673-9259/2/4/21/htm">reviewing</a> the published research to identify 12 factors shown to reduce dementia risk. We surveyed 834 older Australians about their awareness of the 12 factors, which were:</p> <ol> <li>having a mentally active lifestyle</li> <li>doing physical activity</li> <li>having a healthy diet</li> <li>having strong mental health</li> <li>not smoking</li> <li>not consuming alcohol</li> <li>controlling high blood pressure</li> <li>maintaining a healthy weight</li> <li>managing high cholesterol</li> <li>preventing heart disease</li> <li>not having kidney disease</li> <li>not having diabetes</li> </ol> <p><a href="https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext">The Lancet</a> subsequently published its own list of factors that help reduce dementia risk, which covered much the same territory (but included a few others, such as reducing air pollution, treating hearing impairment and being socially engaged).</p> <p>Of course, there is no way to cut your dementia risk to zero. Some people do all the “right” things and still get dementia. But there is <a href="https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext">good evidence</a> managing lifestyle factors help make it <em>less likely</em> you will get dementia over your lifetime.</p> <p>Our study shows many older Australians are quite aware, with over 75% able to correctly identify more than four of the factors in our list of 12.</p> <p>However, few were able to name the less well-known risk factors, such as preventing heart disease and health conditions like kidney disease.</p> <p>The good news is that close to half of the sample correctly identified more than six of the 12 protective factors, with mentally active lifestyle, physical activity and healthy diet in the top three spots.</p> <h2>Two key issues</h2> <p>Two things stood out as strongly linked with the ability to identify factors influencing dementia risk.</p> <p>Education was key. People who received more than 12 years of formal schooling were more likely to agree that dementia was a modifiable condition. We are first exposed to health management in our school years and thus more likely to form healthier habits.</p> <p>Age was the other key factor. Younger respondents (less than 75 years old) were able to accurately identify more protective factors compared to older respondents. This is why health promotion initiatives and public education efforts about dementia are vital (such as Dementia Awareness Month and <a href="https://www.memorywalk.com.au/">Memory, Walk and Jog initiatives</a>).</p> <h2>How can these findings be used in practice?</h2> <p>Our findings suggest we need to target education across the different age groups, from children to older Australians.</p> <p>This could involve a <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/ajag.13049">whole system approach</a>, from programs targeted at <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5858574/#:%7E:text=Family%20Coaching%20has%20specific%20goals,to%20problem%20solve%20challenging%20situations.">families</a>, to educational sessions for school-aged children, to involving GPs in awareness promotion.</p> <p>We also need to tackle barriers that hinder dementia risk reduction. This means doing activities that motivate you, finding programs that suit your needs and schedule, and are accessible.</p> <h2>What does this mean for you?</h2> <p>Reducing your dementia risk means recognising change starts with you.</p> <p>We are all familiar with the everyday challenges that stop us from starting an exercise program or sticking to a meal plan.</p> <p>There are simple and easy changes we can begin with. Our team has developed a program that can help. We are offering limited <a href="https://www.brainbootcamp.com.au/">free brain health boxes</a>, which include information resources and physical items such as a pedometer. These boxes aim to help rural Australians aged 55 years and over to adopt lifestyle changes that support healthy brain ageing.

How to complain about aged care and get the result you want

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/jacqueline-wesson-1331752">Jacqueline Wesson</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/lee-fay-low-98311">Lee-Fay Low</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>It can be hard to know what to say, or who to talk to, if you notice something isn’t right for you or a loved one in residential aged care.</p> <p>You might have concerns about personal or medical care, being adequately consulted about changes to care, or be concerned about charges on the latest bill. You could also be concerned about theft, neglect or abuse.</p> <p>Here’s how you can raise issues with the relevant person or authority to improve care and support for you or your loved one.</p> <h2>Keep records</h2> <p>You can complain about any aspect of care or service. For instance, if medical care, day-to-day support or financial matters do not meet your needs or expectations, you can complain.</p> <p>It is best to act as soon as you notice something isn’t right. This may prevent things from escalating. Good communication helps get better results.</p> <p>Make written notes about what happened, including times and dates, and take photos. Try to focus on facts and events. You can also keep a record of who was involved and their role.</p> <p>Keep track of how the provider responded or steps taken to resolve the issue. Write notes of conversations and keep copies of emails.</p> <h2>Who do I complain to?</h2> <p><strong>Potential criminal matters</strong></p> <p>If you have concerns about immediate, serious harm of a criminal nature then you should contact the police, and your provider immediately. These types of serious incidents include unreasonable use of force or other serious abuse or neglect, unlawful sexual contact, stealing or unexpected death.</p> <p>The provider may have already contacted you about this. They are required to report such <a href="https://www.agedcarequality.gov.au/consumers/serious-incident-response-scheme">serious incidents</a> to both the Aged Care Quality and Safety Commission within 24 hours, and to the police.</p> <p><strong>Other matters</strong></p> <p>For other matters, talk to the care staff involved. Try to find out more detail about what happened and why things went wrong. Think about what you expect in the situation.</p> <p>Then talk to the most senior person in charge, to see if they can make changes so things don’t go wrong in the future. This person may be called the nursing unit manager, care manager or care director.</p> <p>Providers must acknowledge and investigate your complaint, tell you their findings and actions taken, and follow up to see if you are satisfied.</p> <p>If you would like support to talk to the provider, the <a href="https://opan.org.au">Older Persons Advocacy Network</a> can help. This free service provides independent and confidential support to help find solutions with the aged-care provider. The network can also help you lodge a formal complaint.</p> <h2>How to I lodge a formal complaint?</h2> <p>If you are not satisfied with the way your provider responded, you can lodge a complaint with the <a href="https://www.agedcarequality.gov.au">Aged Care Quality and Safety Commission</a>.</p> <p>Be prepared to submit the facts and events, plus emails and correspondence, you have already collected. Think about what you want to happen to resolve the complaint.</p> <p>Each complaint is handled individually and prioritised depending on the risks to you or your loved one. The commission will start its processes within one business day when complaints are urgent. The resolution process took <a href="https://www.agedcarequality.gov.au/sites/default/files/media/acqsc-annual-report-2020-21.pdf">an average 40 days</a> in 2020-21.</p> <p>You can complain confidentially, or anonymously if you feel safer. But the commission may not be able to investigate fully if it’s anonymous. Also, there are limits to what the commission can do. It cannot ask providers to terminate someone’s employment, or provide direct clinical advice about treatment.</p> <p>Sometimes the commission has issued a “non-compliance” notice to the provider (for a failure to meet quality standards), and action may again <a href="https://www.abc.net.au/news/2022-05-02/aged-care-complaint-about-southern-cross-care-young/101009716">be limited</a>. So it is a good idea to check the <a href="https://www.myagedcare.gov.au/non-compliance-checker">non-compliance register</a> beforehand to see if your provider is listed.</p> <h2>What do others complain about?</h2> <p>From October to December 2021, <a href="https://www.agedcarequality.gov.au/sites/default/files/media/acqs-sector-performance-data-oct-dec-2021.pdf">about a third</a> of Australian nursing homes had a complaint made to the commission against them. Some had more than one complaint. More than half of these complaints were lodged by family, friends or other consumers.</p> <p>The top reasons for complaints were about:</p> <ul> <li> <p>adequacy of staffing</p> </li> <li> <p>medication administration or management</p> </li> <li> <p>infectious diseases or infection control</p> </li> <li> <p>personal and oral hygiene</p> </li> <li> <p>how falls are prevented and managed</p> </li> <li> <p>consultation or communication with representatives and/or family members.</p> </li> </ul> <h2>What if I’m still not happy?</h2> <p>If you’re not happy when you receive the commission’s outcome, you can request a review with 42 days.</p> <p>You can also request the <a href="https://www.ombudsman.gov.au">Commonwealth Ombudsman</a> to review the complaint if you’re not satisfied with the commission’s decision or the way the commission handled your complaint.</p> <h2>Remember, you have a right to complain</h2> <p>The <a href="https://agedcare.royalcommission.gov.au">Aged Care Royal Commission</a> spotlighted the neglect and substandard care that can occur in nursing homes. Despite attempts to <a href="https://www.health.gov.au/resources/publications/concepts-for-a-new-framework-for-regulating-aged-care">lift the standard of aged care</a>, we know residents and carers still have concerns.</p> <p>Residents, and their representatives or families, have a legal <a href="https://www.agedcarequality.gov.au/consumers/standards/resources">right to speak up and complain</a>, free from reprisal or negative consequences. This right is also reflected in the <a href="https://www.agedcarequality.gov.au/consumers/consumer-rights">Charter of Aged Care Rights</a>, which providers are legally required to discuss with you and help you understand.</p> <h2>Moving to another facility</h2> <p>If you have exhausted all avenues of complaint or feel conditions have not improved, you may decide to move to another provider or facility, if available. This option may not be possible in rural areas.</p> <p>This is a difficult decision. It takes time, as well as financial and emotional resources. Starting again with a new provider can also be disruptive for everyone, but sometimes it may be the right choice.</p> <hr /> <p><em>Contact the <a href="https://opan.org.au">Older Persons Advocacy Network</a> on 1800 700 600, the <a href="https://www.agedcarequality.gov.au">Aged Care Quality and Safety Commission</a> on 1800 951 822 or the <a href="https://www.ombudsman.gov.au">Commonwealth Ombudsman</a> on 1300 362 072.</em><!-- Below is The Conversation's page counter tag.

Readers response: What advice would you give someone visiting Australia?

<p>We asked our readers what advice they would give to someone travelling to Australia, including where tourists need to see and what hidden gems cannot be missed. Here's what they said. </p> <p><strong>Peggy Rice</strong> - Respect our rules, the outback needs to be researched, swim between flags, don't swim with crocodiles. It's the best country in the world, let's keep it that way. Also do yourself a favour and put Tasmania on your list of beauty.</p> <p><strong>Kay L Bayly</strong> - Number 1 advice! Check distances between desired destinations. It is a much bigger country than most people understand.</p> <p><strong>Michael Pender</strong> - Bring a sense of humour.</p> <p><strong>Toni Stewart</strong> - You will need a year at least to see all the different areas from desert, scrub, rainforest, cities, beaches, country side fabulous little towns and lots of festivals.</p> <p><strong>Maureen Prince</strong> - We don’t have Kangaroos running the streets. Koalas are not in everybody's back yard trees. Whilst we do have snakes you’d be very unfortunate if you were to come across a venomous one. We don’t all go around saying “Good day mate”. Our scenery is incredible. Our food is superb and, best of all, we have good friends who do say “Good day mate”.</p> <p><strong>Tina Shaw</strong> - Leave preconceptions at customs. See who we are and you'll have a fantastic time.</p> <p><strong>Dianne Savage</strong> - Put Tasmania on your must do list.</p> <p><strong>Margaret Higgs</strong> - Use sunscreen, wear a hat, drink lots of fluids.</p> <p><strong>Cheryl Anne</strong> - Don't assume you can cover the whole country in 6 weeks.</p> <p><strong>Sarah Hayse-Gregson</strong> - Obey the beach culture. The flags, lifesavers are there for a reason. If a sign says, “beach closed” there’s no one to assist you if you get into difficulty. Our lifesavers are volunteers, don’t forget that. They give up their free time to monitor the beaches and are highly trained. Never turn your back to the sea.</p> <p><strong>Ann Lusby</strong> - Watch out for drop bears.</p> <p><em>Image credits: Shutterstock </em></p>

Hospice nurse shares what happens to the body after death

<p dir="ltr">A hospice nurse has revealed the reality of what happens to our bodies in the minutes, hours and days after we die. </p> <p dir="ltr">In her efforts to break down the taboo around conversations about death, Julie McFadden, a hospice nurse from the US, posts candid videos about death and dying to help us be more informed and prepared. </p> <p dir="ltr">In Julie’s latest video, she explains exactly what happens to the human body in the moments, hours and days after someone dies. </p> <p dir="ltr">Nurse Julie said that in the immediate moments after death, the body completely relaxes, beginning the first stage of decomposition, called hypostasis.</p> <p dir="ltr">“All of the things in your body that are holding fluids in, relaxes. That's why death can be messy sometimes.”</p> <p dir="ltr">She clarified that because of how relaxed the body becomes, those who have just died may urinate, have bowel movements or experience bodily fluids coming out of their nose, mouth, ears or eyes. </p> <p dir="ltr">Nurse Julie added, “I like to talk about it so people aren't surprised if that happens - very normal and to be expected sometimes.”</p> <p dir="ltr">This is also when the stage of decomposition called autolysis, or “the self-digestion” stage, occurs and enzymes begin to break down oxygen-deprived tissue, also causing the body temperature to drop. </p> <p dir="ltr">As the body settles in the hours after death, Nurse Julie said the blood will begin to pool downward toward the ground.</p> <p dir="ltr">She said, “If you let someone lie there for long enough - which we do sometimes; you don't have to hurry up and make sure your loved one leaves the house - if you turn them you will notice usually the back of their legs the whole backside of them will look purple or darker that's because all their blood is pulling down.”</p> <p dir="ltr">“Gravity is pulling it down.

What’s the difference between liquid and powder laundry detergent? It’s not just the obvious

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/nathan-kilah-599082">Nathan Kilah</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a></em></p> <p>When shopping for a laundry detergent, the array of choices is baffling. All of the products will likely get your laundry somewhat cleaner. But what gets the best outcome for your clothes and your budget?</p> <p>Do you want whiter whites? Do you need enzymes? And what’s the difference between a powder and liquid detergent?</p> <p>As is often the case, knowing more about the chemistry involved will help you answer those questions.</p> <h2>What is a detergent?</h2> <p>The active ingredients in both laundry powders and liquids are “surfactants”, also known as detergents (hence the product name). These are typically charged or “ionic” molecules that have two distinct parts to their structure. One part interacts well with water and the other interacts with oils.</p> <p>This useful property allows surfactants to lift grease and grime from fabrics and suspend it in the water. Surfactants can also form bubbles.</p> <p>Metal salts dissolved in your water can limit the performance of the surfactants. So-called hard water contains lots of dissolved calcium and magnesium salts which can readily form soap scum.</p> <p>Modern laundry detergents therefore contain phosphates, water softeners and other metal “sequestrants” to stop the formation of soap scum. Phosphates can cause algal blooms in fresh water environments. This is why modern detergent formulations <a href="https://accord.asn.au/sustainability/phosphorus-standard/">contain smaller amounts of phosphates</a>.</p> <p>Many products also contain optical brighteners. These chemicals absorb ultraviolet light and release blue light, which provides the “whiter white” or “brighter colour” phenomenon.</p> <p>Laundry detergents typically contain fragrances. These aren’t essential to the chemistry of cleaning, but give the impression the clothes are fresh.</p> <p>Lastly, some laundry detergents contain enzymes – more on those later.</p> <h2>What’s in laundry powder?</h2> <p>While detergents and ingredients to avoid soap scum are the most important components, they aren’t the most abundant. The main ingredients in powders are salts (like sodium sulfate) that add bulk and stop the powder from clumping.</p> <p>Another common salt added to laundry powders is sodium carbonate, also known as washing soda. Washing soda (a chemical cousin of <a href="https://theconversation.com/vinegar-and-baking-soda-a-cleaning-hack-or-just-a-bunch-of-fizz-225177">baking soda</a>) helps to chemically modify grease and grime so they dissolve in water.</p> <p>Laundry powders also frequently contain oxidising agents like sodium percarbonate. This is a stable combination of washing soda and hydrogen peroxide. An additive known as tetraacetylethylenediamine activates the percarbonate to give a mild bleaching effect.</p> <p>Chemically, powders have an advantage – their components can be formulated and mixed but kept separate in a solid form. (You can usually see different types of granules in your laundry powder.)</p> <h2>What’s in laundry liquid?</h2> <p>The main ingredient of laundry liquid is water. The remaining ingredients have to be carefully considered. They must be stable in the bottle and then work together in the wash.</p> <p>These include similar ingredients to the powders, such as alkaline salts, metal sequestrants, water softeners and surfactants.</p> <p>The surfactants in liquid products are often listed as “ionic” (charged) and “non-ionic” (non-charged). Non-ionic surfactants can be liquid by default, which makes them inappropriate for powdered formulations. Non-ionic surfactants are good at suspending oils in water and don’t form soap scum.</p> <p>Liquid detergents also contain preservatives to prevent the growth of microbes spoiling the mixture.</p> <p>There are also microbial implications for inside the washing machine. Liquid products can’t contain the peroxides (mild bleaching agents) found in powdered products. Peroxides kill microbes. The absence of peroxides in liquid detergents makes it more likely for <a href="https://www.mdpi.com/1420-3049/27/1/195#B15-molecules-27-00195">mould biofilms to form</a> in the machine and for bacteria to be transferred between items of clothing.</p> <p>As an alternative to peroxides, liquids will typically contain only optical brighteners.</p> <p>Liquids do have one advantage over powders – they can be added directly to stains prior to placing the item in the wash.</p> <p>A recent “convenience” version of liquid formulas are highly concentrated detergent pods. Colourful and bearing a resemblance to sweet treats, these products have been found to be <a href="https://poisoncenters.org/track/laundry-detergent-packets">dangerous to young children and people with cognitive impairment</a>.</p> <p>Pods also remove the option to add less detergent if you’re running a smaller load or just want to use less detergent in general.</p> <h2>So, what about enzymes?</h2> <p>Enzymes are naturally evolved proteins included in laundry products to remove specific stains. Chemically, they are catalysts – things that speed up chemical reactions.</p> <p>Enzymes are named for the molecules they work on, followed by the ending “-ase”. For example, lipase breaks down fats (lipids), protease breaks down protein, while amylase and mannanase break down starches and sugars.</p> <p>These enzymes are derived from organisms found in cool climate regions, which helps them function at the low temperature of washing water.</p> <p>Running an excessively hot wash cycle can damage or denature the enzyme structure, stopping them from assisting in your wash. Think of an egg white <a href="https://theconversation.com/how-to-make-the-perfect-pavlova-according-to-chemistry-experts-196485">changing from translucent to white while cooked</a> – that’s protein denaturing.</p> <p>If your detergent contains enzymes, the washing temperature should be neither too hot nor too cold. As a guide, temperatures of 15–20°C are used in <a href="https://environment.ec.europa.eu/document/download/557d8ab5-4e75-41a4-a901-1548be7f685d_en">standard laundry tests</a>.</p> <h2>Is powder or liquid better?</h2> <p>We make consumer choices guided by performance, psychology, cost, scent, environmental considerations and convenience.</p> <p>It’s worth experimenting with different products to find what works best for you and fits your needs, household budget and environmental considerations, such as having <a href="https://theconversation.com/curious-kids-why-can-some-plastics-be-recycled-but-others-cant-229270">recyclable packaging</a>.</p> <p>Personally, I wash at 20°C with half the recommended dose of a pleasant-smelling laundry powder, packaged in recyclable cardboard, and containing a wide range of enzymes and an activated peroxide source.</p> <p>Knowing a little chemistry can go a long way to getting your clothes clean.</p> <p>However, laundry detergent manufacturers don’t always disclose the full list of ingredients on their product packaging.</p> <p>If you want more information on what’s in your product, you have to look at the product website. You can also dig a little deeper by reading documents called <a href="https://theconversation.com/a-new-tiktok-trend-has-people-drinking-toxic-borax-an-expert-explains-the-risks-and-how-to-read-product-labels-210278">safety data sheets</a> (SDS).

"What did we do?": Bride shares heartbroken reaction to empty wedding

<p>A bride has recalled the devastating moment she made a grand entrance to her wedding, only to discover almost no guests showed up. </p> <p>Kalina Marie took to TikTok to share the gut-wrenching video of the moment her and her new husband Shane stepped inside the lavishly decorated hall with their son, as they tried to come to terms with the fact that only a handful of people showed to celebrate with them. </p> <p>“This is our entrance to our Masquerade ball,” Ms Marie, who is from Oregon in the US, wrote in the caption of her clip, which has since amassed over seven million views. </p> <p>“The Masquerade ball that I have talked EXCESSIVELY about for the last 10 months. The same ball that I not only digitally invited over 75 people to. But ALSO spent money to send 25 beautiful invitations out to."</p> <p>“FIVE PEOPLE SHOWED UP!!!!!!! Like, are you kidding me!?!? As you see in the video, we enter the venue. And no one is there. The invite said 1pm. My mum messaged me at 1:15pm that no one was there. My husband and I finally showed up at 2 o’clock, to five people, in a venue planned for 40.”</p> <div class="embed" style="font-size: 16px; box-sizing: inherit; margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; outline: currentcolor !important;"><iframe class="embedly-embed" style="box-sizing: inherit; margin: 0px; padding: 0px; border-width: 0px; border-style: none; vertical-align: baseline; width: 600px; max-width: 100%; outline: currentcolor !important;" title="tiktok embed" src="https://cdn.embedly.com/widgets/media.html?src=https%3A%2F%2Fwww.tiktok.com%2Fembed%2Fv2%2F7433899067664551198&amp;display_name=tiktok&amp;url=https%3A%2F%2Fwww.tiktok.com%2F%40kalina_marie_23%2Fvideo%2F7433899067664551198&amp;image=https%3A%2F%2Fp16-pu-sign-useast8.tiktokcdn-us.com%2Fobj%2Ftos-useast8-p-0068-tx2%2F7f29587f56a44788903eea92cd974c62_1730839526%3Flk3s%3Db59d6b55%26x-expires%3D1731499200%26x-signature%3DbUQfTW%252F8BrelG0Dy5rCNSzBBbiQ%253D%26shp%3Db59d6b55%26shcp%3D-&amp;key=5b465a7e134d4f09b4e6901220de11f0&amp;type=text%2Fhtml&amp;schema=tiktok" width="340" height="700" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe></div> <p>She said she “dreamt” that she would walk into a bunch of people “hooting and hollering” for them, but instead ended up having to “hold herself together” because she had “no idea” how to deal with her venue being almost completely empty.</p> <p>“All the wasted food and drinks,” Ms Marie continued. “All the empty tables and chairs. Every moment of my reception changed to adapt.”</p> <p>“It just makes me think, like, why? What did we do? Am I that bad of a person? What did my husband ever do to deserve any of this?” she questioned. “Why couldn’t we matter enough for people to show up?”</p> <p>She revealed that it makes her “sick” that she still has “friends” who haven’t even messaged her to congratulate her or tell her why they didn’t come, adding, “I honestly can’t wrap my head around this yet.”</p> <p>The heart-breaking video quickly wrapped up millions of views and comments, with many empathising with the new bride, with one person writing, "This hurts my heart for you."</p> <p>Thousands of others tried to lighten the mood, praising Ms Marie for how beautiful she looked and vowing to attend a do-over wedding.</p> <p>“NAH, RE-DO THIS. WE ALL SHOWING UP,” read a top comment, while another wrote, “Let’s do it over. This time invite me and the rest of us. We’ll show up and out.

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.

Fasting, eating earlier in the day or eating fewer meals – what works best for weight loss?

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

Your friend has been diagnosed with cancer. Here are 6 things you can do to support them

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/stephanie-cowdery-2217734">Stephanie Cowdery</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/anna-ugalde-2232654">Anna Ugalde</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>; <a href="https://theconversation.com/profiles/trish-livingston-163686">Trish Livingston</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a>, and <a href="https://theconversation.com/profiles/victoria-white-1888110">Victoria White</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a></em></p> <p>Across the world, <a href="https://www.who.int/news/item/01-02-2024-global-cancer-burden-growing--amidst-mounting-need-for-services">one in five</a> people are diagnosed with cancer during their lifetime. By age 85, almost <a href="https://www.cancer.org.au/cancer-information/what-is-cancer/facts-and-figures">one in two</a> Australians will be diagnosed with cancer.</p> <p>When it happens to someone you care about, it can be hard to know what to say or how to help them. But providing the right support to a friend can make all the difference as they face the emotional and physical challenges of a new diagnosis and treatment.</p> <p>Here are six ways to offer meaningful support to a friend who has been diagnosed with cancer.</p> <h2>1. Recognise and respond to emotions</h2> <p>When facing a cancer diagnosis and treatment, it’s normal to experience a range of <a href="https://www.canceraustralia.gov.au/impacted-by-cancer/emotions#:%7E:text=It's%20likely%20that%20feelings%20will,these%20feelings%20ease%20with%20time">emotions</a> including fear, anger, grief and sadness. Your friend’s moods may fluctuate. It is also common for feelings to <a href="https://link.springer.com/article/10.1007/s00520-014-2492-9">change over time</a>, for example your friend’s anxiety may decrease, but they may feel more depressed.</p> <p>Some friends may want to share details while others will prefer privacy. Always ask permission to raise sensitive topics (such as changes in physical appearance or their thoughts regarding fears and anxiety) and don’t make assumptions. It’s OK to tell them you feel awkward, as this acknowledges the challenging situation they are facing.</p> <p>When they feel comfortable to talk, follow their lead. Your support and willingness <a href="https://www.cancervic.org.au/get-support/stories/what-to-say-and-not-say.html">to listen without judgement</a> can provide great comfort. You don’t have to have the answers. Simply acknowledging what has been said, providing your full attention and being present for them will be a great help.</p> <h2>2. Understand their diagnosis and treatment</h2> <p><a href="https://onlinelibrary.wiley.com/doi/full/10.1002/pon.4722">Understanding</a> your friend’s diagnosis and what they’ll go through when being <a href="https://www.cancer.org/cancer/caregivers/what-a-caregiver-does/treatment-timeline.html">treated</a> may be helpful.</p> <p>Being informed can reduce your own worry. It may also help you to listen better and reduce the amount of explaining your friend has to do, especially when they’re tired or overwhelmed.</p> <p>Explore reputable sources such as the <a href="https://www.cancer.org.au/">Cancer Council website</a> for accurate information, so you can have meaningful conversations. But keep in mind your friend has a trusted medical team to offer personalised and accurate advice.</p> <h2>3. Check in regularly</h2> <p>Cancer treatment can be isolating, so regular check-ins, texts, calls or visits can help your friend feel less alone.</p> <p>Having a normal conversation and sharing a joke can be very welcome. But everyone copes with cancer differently. Be patient and flexible in your support – some days will be harder for them than others.</p> <p>Remembering key dates – such as the next round of chemotherapy – can help your friend feel supported. Celebrating milestones, including the end of treatment or anniversary dates, may boost morale and remind your friend of positive moments in their cancer journey.</p> <p>Always ask if it’s a good time to visit, as your friend’s immune system <a href="https://www.cancerresearchuk.org/about-cancer/what-is-cancer/body-systems-and-cancer/the-immune-system-and-cancer#:%7E:text=to%20fight%20cancer-,Cancer%20and%20treatments%20may%20weaken%20immunity,high%20dose%20of%20steroids">may be compromised</a> by their cancer or treatments such as chemotherapy or radiotherapy. If you’re feeling unwell, it’s best to postpone visits – but they may still appreciate a call or text.</p> <h2>4. Offer practical support</h2> <p>Sometimes the best way to show your care is through practical support. There may be different ways to offer help, and what your friend needs might change at the beginning, during and after treatment.</p> <p>For example, you could offer to pick up prescriptions, drive them to appointments so they have transport and company to debrief, or wait with them at appointments.</p> <p>Meals will always be welcome. However it’s important to remember cancer and its treatments may <a href="https://www.cancer.gov/about-cancer/treatment/side-effects/nutrition#effects-of-cancer-treatment-on-nutrition">affect</a> taste, smell and appetite, as well as your friend’s ability to eat enough or absorb nutrients. You may want to check first if there are particular foods they like. <a href="https://www.cancervic.org.au/downloads/resources/booklets/nutrition-cancer.pdf">Good nutrition</a> can help boost their strength while dealing with the side effects of treatment.</p> <p>There may also be family responsibilities you can help with, for example, babysitting kids, grocery shopping or taking care of pets.</p> <h2>5. Explore supports together</h2> <p>Studies <a href="https://pubmed.ncbi.nlm.nih.gov/35834503/">have shown</a> mindfulness practices can be an effective way for people to manage anxiety associated with a cancer diagnosis and its treatment.</p> <p>If this is something your friend is interested in, it may be enjoyable to explore classes (either online or in-person) together.</p> <p>You may also be able to help your friend connect with organisations that provide emotional and practical help, such as the Cancer Council’s <a href="https://www.cancer.org.au/support-and-services/cancer-council-13-11-20">support line</a>, which offers free, confidential information and support for anyone affected by cancer, including family, friends and carers.</p> <p><a href="https://www.researchgate.net/publication/5659099_Systematic_review_of_peer-support_programs_for_people_with_cancer">Peer support groups</a> can also reduce your friend’s feelings of isolation and foster shared understanding and empathy with people who’ve gone through a similar experience. GPs <a href="https://pubmed.ncbi.nlm.nih.gov/34333571/">can help</a> with referrals to support programs.</p> <h2>6. Stick with them</h2> <p>Be committed. Many people feel <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11120751/">isolated</a> after their treatment. This may be because regular appointments have reduced or stopped – which can feel like losing a safety net – or because their relationships with others have changed.</p> <p>Your friend may also experience emotions such as worry, lack of confidence and uncertainty as they adjust to a <a href="https://www.cancer.gov/about-cancer/coping/survivorship/new-normal">new way of living</a> after their treatment has ended. This will be an important time to support your friend.</p> <p>But don’t forget: looking after <a href="https://www.healthdirect.gov.au/caring-for-someone-with-cancer">yourself</a> is important too. Making sure you eat well, sleep, exercise and have emotional support will help steady you through what may be a challenging time for you, as well as the friend you love.</p> <p><a href="https://www.deakin.edu.au/faculty-of-health/research/cancer-carer-hub">Our research</a> team is developing new programs and resources to support carers of people who live with cancer. While it can be a challenging experience, it can also be immensely rewarding, and your small acts of kindness can make a big difference.<!-- Below is The Conversation's page counter tag.
