Drinking red wine (in moderation) could be good for your gut, according to researchers from the UK. The team from King’s College London says red wine contains compounds that help increase the number of different types of bacteria that live in the gut. The micronutrients, known as polyphenols, are more abundant in red wine vs. beer, cider and white wine, and act as fuel for microbes living inside the bowel. Polyphenols are found in many fruits and vegetables, including the grapes used to make red wine. The researchers say even just one glass of red wine a fortnight can make a difference, but warn that their findings should not be used as an excuse to binge drink. Publishing its research in the journal Gastroenterology, the team said the “friendly” bugs in our gut help keep us healthy. Even small changes in our gut microbiota – the community of bugs that live there – can make us more susceptible to conditions like obesity, heart disease and Irritable Bowel Syndrome. The gut microbiota of people who drink red wine was found to be more diverse than that of those who do not drink wine. Furthermore, the more wed wine consumed, the greater the levels of diversity – although it’s important to note that nobody involved in the trial was a heavy drinker. Speaking about the findings of their research, Dr Caroline Le Roy said: “If you must choose one alcoholic drink today, red wine is the one to pick as it seems to potentially exert a beneficial effect on you and your gut microbes, which in turn may also help weight and risk of heart disease.”
A pill that contains four different medicines and is designed to be taken daily could dramatically reduce the number of heart attacks and strokes, a new study has found. The polypill – which is the generic term used to describe a medication that contains multiple active pharmaceutical ingredients – contains aspirin, a cholesterol-lowering statin and two drugs to reduce blood pressure. For the study, researchers from Iran and the UK studied around 6,800 people from more than 100 villages in Iran. Half were given the polypill and advice on how to improve their health through lifestyle changes and the other half were just given the lifestyle changes advice. After five years, the group taking the polypill had experienced 202 cardiovascular events, while the group that had just been given the advice had experienced 301 cardiovascular events. In other words, the group taking the polypill had experienced around a third less cardiovascular events. The researchers say the pill costs just pennies a day, but could have a huge impact, especially in poorer countries where doctors have fewer options available to them. Stroke and coronary heart disease are the top two causes of death worldwide, killing more than 15 million people each year. Obesity, smoking and doing little exercise are all risk factors associated with an unhealthy heart. Based on the findings of the study, if 35 people were all given the polypill daily, it would prevent one of them developing a major heart problem within 5 years. “Given the polypill's affordability, there is considerable potential to improve cardiovascular health and to prevent the world's leading cause of death,” said Dr Nizal Sarrafzadegan, of Isfahan University of Medical Sciences, Iran. The findings of the research are published in The Lancet.
If you’re looking to lose some weight, eating earlier in the day and intermittently fasting could help, new research suggests. According to a paper published in the journal Obesity, the timing of meals and intermittent fasting influences metabolism, which can have an impact on weight loss. Researchers discovered this following a trial involving 11 men and women, all of who were in good health, aged between 25 and 45 years and carrying some excess weight. The trial participants were split into two groups: one who ate breakfast at 08:00 and then ate their last meal of the day at 14:00, and another who ate breakfast at 08:00 and had their last meal of the day at 20:00. Both groups ate the same meals each day. At the end of the trial, participants underwent a battery of tests in a respiratory chamber to assess their metabolism. The number of calories, fat, carbohydrates and proteins burned were all measured. It was revealed that the participants who ate their last meal of the day at 14:00 and, therefore, fasted longer overnight, burned more fat than the other group. They also had lower levels of the hunger hormone ghrelin. “Eating in sync with circadian rhythms by eating early in the daytime appears to reduce body weight and improve metabolic health,” the authors of the paper wrote.
A leading UK cancer charity has warned that obesity now causes more cases of four common cancers than smoking. According to Cancer Research UK, bowel, kidney, ovarian and liver cancers are more likely to be caused by being overweight than by smoking tobacco. The warning is particularly concerning as obese people outnumber smokers by two to one in the UK, which means millions of people are at risk of developing any of these cancers simply because they are overweight. Despite the fact that smoking remains the number one preventable cause of cancer in the UK and causes more cases of cancer than being overweight each year (54,300 vs. 22,800), for the four cancers previously mentioned, obesity causes more. However, Cancer Research UK’s latest billboard campaign highlighting the risks associated with being overweight has been accused of fat-shaming. And it’s not the first time the charity has been picked up for this either. Nevertheless, the charity remains adamant that outlining the risks of being overweight when it comes to cancer is an important step. Speaking about the Cancer Research UK warning, the British Medical Association said: “While we are very much aware of the health risks associated with smoking, less effort has been thrown behind tackling obesity, which is now a major cause of cancer.”
Children whose parents divorce are more likely to get fat than their peers whose parents stay together, new research has revealed. According to the study by researchers from the London School of Economics and Political Science, children whose parents divorce before they are six are particularly impacted. For the study, the researchers analysed data collected by the UK Millennium Cohort Study on 7,574 children born between 2000 and 2002. Of the children involved, 1,573 (around one in five) had witnessed their parents divorce by the time they were 11. These kids gained more weight in the 24-month period following their parents’ divorce than their peers whose parents remained together. Furthermore, the kids whose parents had divorced were also more likely to become overweight or obese within 36 months of their parents separating. The authors of the paper say their findings underline how much of an impact a divorce can have on children and that parental separation is “a process with potentially long-lasting consequences”. As a result, the authors are calling for more health help and support to be given to families going through a break-up. The paper also offers some reasons why children put on weight following a divorce, namely: There’s often less money in separated households for fresh fruit and vegetables Parents having to work longer hours, so there’s less time to prepare nutritious food There’s often less money for extra-curricular activities, including sport Parents with less time and energy to promote healthy eating habits in their children Emotional problems leading to parents overfeeding their children and kids eating too much sugary and fatty food
With more than 37% of American adults living with obesity, and more than 32% overweight, any strategies for curbing weight gain should be closely examined to see if they could help the situation. Now, new research suggests that weighing ourselves every day could effectively prevent weight gain – especially over the usually over-indulgent holiday period. Published in the journal Obesity, the research was led by Jamie Cooper, Ph.D., associate professor at the University of Georgia in Athens. For the study, Cooper and colleagues recruited 111 adults aged between 18 and 65. Each participant was told to try and maintain their starting weight during the holiday season, but wasn’t given any advice on how to do this. Instead, the participants were all told to weigh themselves – some daily and others less frequently. At the end of the 14-week trial, the participants who weighed themselves every day either maintained their starting weight or actually lost weight. In contrast, the participants who did not weigh themselves every day all gained weight. The researchers suggest that by weighing themselves every day and being able to exercise more/eat less to combat small weight increases, those participants were able to maintain their starting weight or lose weight. Speaking about the findings of the research, Study co-author Michelle vanDellen, said: “People are really sensitive to discrepancies or differences between their current selves and their standard or goal. When they see that discrepancy, it tends to lead to behavioural change. Daily self-weighing ends up doing that for people in a really clear way.”
A major study has found that the UK has a big obesity problem, and that there are severe health implications for people who are even just a little overweight. According to the research, which was funded by healthcare firm Novo Nordisk, individuals with a Body Mass Index (BMI) of 30-35 were 70% more likely to develop heart failure than their healthy weight peers (18.5-25 BMI). Furthermore, the study of 2.8 million adults also showed that people who were even slightly overweight were twice as likely to develop Type 2 diabetes. The study, which is due to be presented at the European Congress on Obesity (ECO) in Glasgow, also revealed: The risk of Type 2 diabetes for people with a BMI of 35-40 was almost nine times higher People with severe obesity (BMI of 40-45) were 12 times more likely to develop Type 2 diabetes People with severe obesity also had triple the risk of heart failure, high blood pressure, and dyslipidaemia (elevated levels of total or low-density lipoprotein (LDL) cholesterol levels, or low levels of high-density lipoprotein (HDL) cholesterol) A BMI of 40-45 was also linked with a 50% higher risk of dying prematurely from any cause Speaking about the findings of the study, Public Health England said “sustained action” was needed to tackle obesity.
For busy parents, occupying their children with a tablet or cell phone for short periods throughout the day provides some much-needed relaxation time. But while it’s often been said that young children shouldn’t spend too much time with their faces glued to screens, a little here and there doesn’t hurt, right? Well, actually, it might… That’s because the World Health Organization (WHO) has recently issued new guidelines that state children under two should have zero sedentary screen time (that includes TVs, tablets and video games). The limit for two- to four-year-olds, the WHO says, should be an hour a day, and less is always better. In light of the new WHO advice, UK health ministers have said they will not amend their own guidelines, which currently advise no screen time before bedtime, but do not set maximum time limits. The new WHO guidelines are designed to tackle the practice of giving young children screens for entertainment purposes e.g. handing them a cell phone or sitting them down in front of a TV. The reason for this is to combat childhood inactivity, which can lead to obesity-related ill health and is a leading risk factor for global mortality.
As obesity rates across the world continue to rise, understanding exactly why we put on weight has never been more important. That’s why the findings of a new study, which looked at whether there is an association between when we eat and how much weight we gain, could be very significant. Presenting their findings at the ENDO 2019 conference, which took place in New Orleans, the scientists from the University of Colorado in Denver said there is a link between eating later in the day and having a higher BMI, as well as more body fat. For the study, 31 adults who were either overweight or obese and had an average age of 36 years were closely monitored to assess their sleep, levels of activity, and diet. Interestingly, the study also showed that the participants who ate later in the day still had an average of 7 hours sleep each night, suggesting that lack of sleep may not promote obesity after all. Speaking about the findings of the study, Dr. Adnin Zaman, lead author, said “These findings support our overall study, which will look at whether restricting the eating window to earlier on in the day will lower obesity risk.”
Following a low-calorie diet – even for just a few months – can arrest type-2 diabetes for at least two years, new research suggests. The findings of the study highlight that type-2 diabetes might not necessarily be the life sentence we previously thought. Nearly 300 people with type-2 diabetes in Scotland and Tyneside (in the UK) participated in the study. Half were given standard diabetes care, while the other half were put on a structured weight management programme. After 12 months, 46% of those on the low-calorie programme had successfully reversed their type-2 diabetes. In comparison, just 4% of the study participants given the standard treatment had gone into remission. Two years later, 36% of the study participants on the structured weight management programme were still in remission. “People with type 2 diabetes and healthcare professionals have told us their top research priority is: ‘Can the condition be reversed or cured?’ We can now say, with respect to reversal, that yes it can. Now we must focus on helping people maintain their weight loss and stay in remission for life,” said Prof Mike Lean from Glasgow University, who led the study with Taylor. Type-2 diabetes causes blood sugar levels to rise and can lead to serious complications such as amputations, visual problems and heart disease. It is thought that one in 16 adults in the UK is currently living with type-2 diabetes, a condition that is fuelled by obesity. [Related reading: Why being overweight increases your risk of cancer]
People who have sedentary jobs could significantly boost their lifespans by taking short, regular movement breaks, a new study has found. It’s no secret that individuals who spend a lot of time sitting down are more likely to develop certain adverse health conditions, such as diabetes, obesity and cardiovascular diseases, as well as having increased risk of osteoporosis, depression, anxiety, colon cancer and high blood pressure. However, just a small amount of exercise, the study suggests, could lower the risk of early death. According to the research – the findings of which are published in the Annals of Internal Medicine – individuals who sat for less than 30 minutes at a time had the lowest risk of early death. For example, workers who had a movement break (involving some low-intensity exercise) every 30 minutes had a 17% lower risk of death than their counterparts who did not have any breaks. Moreover, individuals who broke up periods of sitting every 30 minutes with moderate- to high-intensity exercise lowered their risk of early death by 35%. Speaking about the findings of the research, Keith Diaz, an assistant professor of behavioural medicine at Columbia University Vagelos College of Physicians and Surgeons in New York City and study lead, said: “If you have a job or lifestyle that involves a lot of sitting, you can lower your risk of early death by moving more often, for as long as you want and as your ability allows — whether that means taking an hour-long high-intensity spin class or choosing lower-intensity activities, like walking.”
Christmas Day is less than two weeks away and that means many of us will soon be gorging ourselves on all sorts of culinary delights. It’s a reality that will see a lot of people piling on the pounds this month ahead of the inevitable January fitness drive. But what if there was a simple way to limit the impact of Christmas feasting on our waistlines? A new study by the Universities of Birmingham and Loughborough in the UK suggests there is. According to the study involving 272 volunteers, regular home weigh-ins coupled with simple weight-loss tips can prevent people from putting on weight over the festive period. For the study, the volunteers were divided into two groups. One group weighed themselves regularly and were given dietary advice, including information on how many calories they needed to burn to negate Christmas food. The other group didn’t weight themselves and were only given a small amount of healthy lifestyle advice. The group that weighed themselves and had access to the additional information weighed 0.49kg less than the "comparison" group come the end of the study. Study lead author, Frances Mason, of the University of Birmingham's Institute of Applied Health Research, said “People gain a kilo of weight on average annually. Often this weight gain happens at Christmas, and is never fully lost. This could possibly be a factor driving the obesity epidemic.” In other words, by simply keeping track of your weight and understanding the impact the foods you are eating are having on your waistline, you stand a better chance of avoiding weight gain at a time of year that’s traditionally associated with piling on the pounds.

According to the World Health Organization (WHO), obesity is a “global epidemic” that must be tackled if we are to prevent its ill effects. In the United States, nearly 40% of adults and 18.5% of children aged 2 to 19 are obese. Obesity is a major risk factor for type-2 diabetes, heart disease and some types of cancer. That’s why finding effective ways to treat the condition is paramount. But now scientists say they are on the verge of creating a pill that could make obesity a thing of the past - without the need for diet and exercise. Sounds too good to be true, right? Nevertheless, the team at Flinders University in South Australia say that they key to curbing obesity could lie in a single gene known as RCAN1. The team found that when RCAN1 was removed in mice and they were then fed a high fat diet, they did not gain weight. In fact, they could eat as much food as they wanted over a prolonged period of time, the researchers say. Damien Keating, Ph.D., professor of molecular and cellular physiology at Flinders, and leader of the research team, said blocking RCAN1 allows the body to transform unhealthy white fat into calorie-burning brown fat. Stunning pictures of the mice used for the trial highlight the difference when RCAN1 was blocked and when it wasn’t. The results of the research are published in the journal EMBO Reports.
We are often told that being overweight increases our risk of cancer. In fact, in the UK, obesity is the biggest preventable cause of cancer after smoking, according to Cancer Research UK. But why does being overweight increase a person’s likelihood of developing cancer? A group of scientists say they now know. The team from Trinity College Dublin say the reason overweight people are at greater risk of developing cancer is because a certain cell in the body that’s used to destroy cancer gets clogged with fat and stops working as a result. Publishing their findings in the Nature Immunology journal, the team said they were able to show that the body’s natural cancer-fighting cells get clogged by fat. They are hopeful that new drug treatments can be developed that will reverse the effects and restore the cancer-killing ability of said cells. Until then, though, the best advice remains to stay a healthy weight, stop smoking and cut down on alcohol. Speaking about the findings of the research, Dr Leo Carlin, from the Cancer Research UK Beatson Institute, said: “Although we know that obesity increases the risk of 13 different types of cancer, we still don't fully understand the mechanisms underlying the link. “This study reveals how fat molecules prevent immune cells from properly positioning their tumour-killing machinery, and provides new avenues to investigate treatments.” [Related reading: Major study finds eating processed meat raises risk of breast cancer]
By 2043, obesity will surpass smoking to be the biggest preventable cause of cancer in UK women. That’s one of the shocking new predictions to come out of a report by Cancer Research UK. At present, around 7% of cancers in women are linked to being overweight and obese, while 12% are said to be caused by smoking. But as the number of individuals who smoke continues to fall and obesity rates continue to rise, the UK cancer charity believes that gap will completely disappear over the next 25 years (assuming current trends continue). In fact, by 2035, the percentage of cancers caused by smoking and by carrying excess weight will almost be equal (25,000 cancer cases each year related to smoking vs. 23,000 related to being overweight). However, after just another eight years (by 2043), being overweight and obese is likely to be linked to even more cases of cancer in women than smoking. Interestingly, the cancer charity says that obesity will not overtake smoking as the leading cause of cancer in men until some time later. The reason for this, though, is simply because more men than women smoke. While obesity is more prevalent among men too, it is thought to be a greater catalyst in women for developing cancer. Professor Linda Bauld, Cancer Research UK's prevention expert, said the UK government must act now to stem the tide of obesity-related cancers. “That's why we are raising awareness of the link between cancer and obesity and calling for measures to protect children, like a ban on junk food adverts before 9pm and for restrictions on price promotions of 'less healthy' products,” she said. Smoking-related cancers include: acute myeloid leukaemia lung bladder bowel cervical pancreatic stomach Obesity-related cancers include: bowel gall bladder kidney liver breast ovarian thyroid
We recently wrote about how foods packed with good bacteria provide no benefits. Now, new research is dragging yoghurts under the spotlight because of the amount of sugar many contain. In fact, according to the research led by Leeds University in the UK, some yoghurts contain more sugar per 100g than cola. Publishing their findings in the journal BMJ Open, the team of researchers said that even organic yoghurts often contain way too much sugar. The only yoghurts, they said, that can be considered low in sugar are natural and Greek-style. For the research, the team analysed 900 different yoghurts on sale in supermarkets in the UK. Perhaps unsurprisingly, yoghurt deserts were found to contain the most sugar (an average of 16.4g per 100g). More surprising, though, are the findings relating to organic yoghurts. That’s because many people see them as a healthy option, not knowing they contain so much sugar. The UK government are trying to reduce the amount of sugar consumed by the public and yoghurts are one of the areas they want to see addressed. This new research underlines why. To be classed as ‘low sugar’ a product needs to contain no more than 5g of sugar per 100g. Just 9% of the yoghurts studied were found to be below this threshold. Dr Bernadette Moore, lead researcher of the study, said: “I think people, including parents, will be surprised to know just how much sugar there is in yoghurt. “My advice would be to buy natural yoghurt and mix in your own fruit.”
If you’re trying desperately to lose weight, you’ll know that diets are difficult. But did you also know that the old trick of using a smaller plate when you eat to reduce portion sizes also (apparently) doesn’t work? That’s the finding of a new study that analysed how tricking the brain with a smaller plate doesn’t work when someone is hungry. According to the study by researchers at Ben-Gurion University of the Negev (BGU), “plate size doesn’t matter as much as we think it does” – especially when people are food deprived. For the study, the results of which were published in the peer-reviewed journal Appetite, the researchers set to out to see if people could identify pizza portion sizes when they were placed on plates of differing sizes. They found that people who had not eaten for at least three hours prior to the test were more likely to identify the pizza portions on both smaller and larger plates than their counterparts who were not hungry. Interestingly, this only happened when applied to food, with both groups similarly inaccurate when asked to compare the size of black circles placed within different sized circles. The researchers say this shows that hunger plays a role in heightening the analytical abilities of individuals. "Over the last decade, restaurants and other food businesses have been using progressively smaller dishes to conform to the perceptual bias that it will reduce food consumption," says Dr. Ganel, head of the Laboratory for Visual Perception and Action in BGU's Department of Psychology. "This study debunks that notion. When people are hungry, especially when dieting, they are less likely to be fooled by the plate size, more likely to realize they are eating less and more prone to overeating later."
Some of us turn to food for comfort when we are feeling emotional or stressed. Likewise, some of us cut back on food when we are feeling upset. But they are habits that could be influencing our children too. That’s because new research by University College London has found that children who eat more or less when stressed or upset have learnt the behaviour rather than inherited it, suggesting home environments are the primary cause of emotional eating. Parental acts such as giving children their favourite food when they are feeling upset have been highlighted as potential reasons for the habits forming. But UK-based eating disorder charity Beat says parents shouldn’t be blamed for their children’s eating issues. "Eating disorders are complex mental illnesses and never have one sole cause," the charity said. The study, which was published in the journal Pediatric Obesity, analysed 398 four-year-old British twins. Half came from families with obese parents and half from parents with a healthy weight. The parents were asked questions about their children’s eating habits, including their tendencies to emotionally eat. The researchers compared the questionnaire data relating to eating disorders between identical and non-identical twins and found very little difference between the two, which suggests environment plays a bigger role than genes.
Have you ever encountered someone who calls themself ‘fat but fit’? It’s not uncommon to meet people who are clearly overweight, yet not perturbed by their situation because they consider themselves to be fit and healthy. However, a large study conducted in America has found that women who are overweight or obese but otherwise healthy are still at an increased risk of cardiovascular disease (CVD). For the study, researchers from the German Institute of Human Nutrition Potsdam-Rehbruecke tracked the health of some 90,257 women in the US over a 30-year period. They found that women who were overweight or obese, but had none of the typical cardiovascular risk factors, such as high blood pressure, excess cholesterol and diabetes, were 20% and 39% more likely to develop cardiovascular disease than their normal weight and metabolically healthy peers. Speaking about the findings of the study, Prof Matthias Schulze, who led it, said: "Our large cohort study confirms that metabolically healthy obesity is not a harmless condition, and even women who remain free of metabolic diseases for decades face an increased risk of cardiovascular events.” The study also found women who were of normal weight, but metabolically unhealthy, were over two-times more likely to develop cardiovascular disease than their peers of the same weight who were metabolically healthy. Jeremy Pearson, associate medical director at the British Heart Foundation, added: "This large scale study confirms that obesity, even if unaccompanied by other warning signs, increases risk of cardiovascular disease in women."
From Friday, drinks manufacturers in the UK will have to pay a levy on the high-sugar drinks they sell, following the implementation of the ground-breaking sugar tax in the country. While ministers and campaigners say the tax is already driving positive results, with many manufacturers cutting the amount of sugar in their drinks ahead of the change, others say it’s still too early to tell. Indeed, while Fanta, Ribena and Lucozade have cut the sugar content of their drinks, Coca-Cola hasn’t. The UK joins a small handful of countries, including France, Mexico and Norway, which have introduced similar taxes in an attempt to reduce sugar consumption. Manufacturers will need to pay the levy – equivalent to 24p per litre - on any of their drinks that contain more than 8g per 100ml. It is not yet known whether the costs will be passed on to consumers in the form of price increases. Drinks containing 5-8g of sugar per 100ml will be subject to a lower rate of tax of 18p per litre. Pure fruit juices that do not contain any added sugar will be exempt, as are drinks with high milk content (due to the beneficial calcium they contain). The new tax is expected to raise around £240 million a year, which will be invested in schools sports and breakfast clubs.
Are you partial to blueberry muffins? If you are, did you ever stop and think that just one could contain more than your entire recommended daily sugar allowance? According to an analysis in January by Action on Sugar and the Obesity Health Alliance, a single blueberry muffin can contain as much as eight teaspoons of sugar. The recommended daily intake for adults in the UK is just seven and it’s even less for children. The analysis highlights just how easy it is for people to exceed the recommended daily intake without even knowing it. For the analysis, Action on Sugar and the Obesity Health Alliance looked at 28 different muffins sold in a variety of locations, such as train stations and supermarkets. It found that 61% contained at least six teaspoons of sugar. Furthermore, muffins purchased at train station retailers had 19% more sugar per portion and were 32% bigger than those found in supermarkets. Caroline Cerny, from the Obesity Health Alliance, said: "We may think grabbing a blueberry muffin is a reasonably healthy option for a snack on the go compared to other cakes or a chocolate bar - yet the figures suggest otherwise. "There is huge variation in both the size of muffins and the sugar content, and with limited nutrition labelling, it's all too easy to eat a huge amount of sugar in just one serving."
As part of a new obesity drive, Public Health England is telling people in the UK to “get on a diet” and wants to cut portion sizes of some of the nation’s most popular foods. Pizzas, ready meals, takeaways and processed meat will all be targeted as part of the initiative to cut calorie consumption by 20% by 2024. In addition, the government agency has called on the food industry to start using healthier ingredients and encourage people to choose lower calorie foods. The drive to eat healthier will not only improve the health of the nation, but also reduce the burden on the NHS associated with obesity-related illnesses. Public Health England says the cost per year of obesity to the NHS is £6 billion. Combined with the sugar reduction programme that came into effect last year and the sugary drinks levy which comes into force next month, this new initiative will also help reduce the number of calories consumed by children in the UK. Talking about the new steps, Public Heath England chief executive Duncan Selbie said: "Britain needs to go on a diet. Children and adults routinely eat too many calories, and it's why so many are overweight or obese." Food manufacturers, supermarkets, takeaways and fast-food outlets have all been told they need to reduce the calories in the foods such as crisps and savoury snacks, cooking sauces and dressings, ready meals and takeaways, and food-to-go like sandwiches. If these companies do not listen to PHE, the agency said it would be willing to ask the government to legislate. Guidelines suggest that women eat no more than 2,000 calories a day, while men should limit themselves to 2,500.
Diabetes has long been split into two types: type 1 and type 2. But new research suggests it could actually be five different diseases and treatment could be tailored to tackle each form. Researchers in Sweden and Finland say the more complicated diabetes picture they’ve uncovered could lead to a new era of personalised medicine being ushered in. Affecting approximately one in 11 people around the world, diabetes doesn’t just play havoc with blood sugar levels, but also increases the risk of stroke, blindness, heart attack, kidney failure and limb amputation. Type 1 diabetes, which affects around 10% of sufferers in the UK, is a disease of the immune system that attacks the body’s insulin factories, leading to there being a shortage of the hormone to control blood sugar levels. Type 2 diabetes, on the other hand, is associated with poor lifestyle choices and obesity, which affect the way in which insulin works. For the study, the researchers analysed blood samples from 14,775 patients. They found that people could be separated into five distinct diabetes clusters. Talking to the BBC, Prof Leif Groop, one of the researchers, said: "This is extremely important, we're taking a real step towards precision medicine. "In the ideal scenario, this is applied at diagnosis and we target treatment better."
New research published in the Journal of the American Heart Association shows that waist-to-hip ratio is a better heart attack predictor than body mass index (BMI), with so-called “apple shape” women at greater risk than their male counterparts. According to the research from the George Institute for Global Health, waist-to-hip ratio is an 18% better heart attack predictor than BMI in women and 6% in men. However, the research also found that BMI was linked to heart disease risk in both sexes. For the research, the team from the George Institute in Oxford interviewed nearly 500,000 UK adults aged 40 to 69. They found women who had bigger waists relative to their hips are at more risk of heart attacks than men with similar body shapes. Speaking about the findings of the research, Ashleigh Doggett, senior cardiac nurse at the British Heart Foundation, said: "Considering the large amount of UK participants, this is a very interesting study which highlights that obesity remains a risk factor for heart attacks in both men and women. "Interestingly, it suggests that those of us who are 'apple' as opposed to 'pear' shape, especially women, may be at higher risk of a heart attack.” The researchers say their findings suggest the differences in the way men and women store fat may affect their risk of heart disease. While more research is needed, these findings do support the notion that being “apple shape” (having proportionally more fat around the abdomen) is more hazardous for your health than being “pear shape” (having proportionally more fat stored around the hips. The full findings of the research can be found in the Journal of the American Heart Association.
By the time they reach middle age, seven in 10 UK millennials (people born between the early 1980s and mid-90s) will be too fat, health experts say. In fact, millennials are on course to be the fattest generation ever since records began. In comparison, only about half of the so-called “baby boomer” generation (those born just after the Second World War) were fat at middle age. It’s a worrying revelation, especially as being fat as an adult is linked to an increased risk of developing 13 different types of cancer, according to Cancer Research UK who conducted the research. The charity said only 15% of the UK population are aware that being fat puts them at increased risk of breast, bowel and kidney cancer. Even more sobering is the fact Britain is now the most obese country in Western Europe and its obesity rates are rising faster than any other developed nation. In 1993, obesity prevalence was 15%, but that figure had almost doubled risen to 27% in 2015. Professor Linda Bauld from Cancer Research UK said: "Extra body fat doesn't just sit there; it sends messages around the body that can cause damage to cells. "This damage can build up over time and increase the risk of cancer in the same way that damage from smoking causes cancer.”
It’s natural for grandparents to dote on their grandchildren and give them sweet treats whenever they see them. But new research suggests this and other influences could have a negative impact on their grandchildren’s health. For the research, the team from the University of Glasgow analysed 56 different studies which included data from 18 countries, including the UK, US, China and Japan. They focused on the influence of grandparents who were significant in their grandchildren’s lives, but who weren’t necessarily primary caregivers. Three areas of influence were considered: diet and weight, physical activity and smoking. When it came to their grandchildren’s diet and weight, grandparents were found to have an adverse impact, with many studies highlighting how they feed their grandchildren high-sugar or high-fat foods - often in the guise of a treat. The researchers also found that grandchildren were perceived to get too little exercise while under the supervision of their grandparents. However, this did depend on whether the grandparents were physically active themselves or not. Furthermore, smoking around grandchildren became an area of conflict between parents and grandparents, with the latter often smoking while their grandchildren were present, even though they had been asked not to. Talking about the findings of the study, lead researcher Dr Stephanie Chambers said: "While the results of this review are clear that behaviour such as exposure to smoking and regularly treating children increases cancer risks as children grow into adulthood, it is also clear from the evidence that these risks are unintentional. "Given that many parents now rely on grandparents for care, the mixed messages about health that children might be getting is perhaps an important discussion that needs to be had."
We recently reported that childhood obesity rates are 10 times higher today than they were in 1975. This worrying trend is only set to continue unless more is done to tackle obesity in children. So-called “sugar taxes” on soft drinks in various countries around the world and France’s decision to ban unlimited fizzy drinks in restaurants, fast food-chains, schools and holiday camps, are definitely steps in the right direction. Now, hospitals in England have laid out plans to ban the sale of any sweets or chocolate that contain more than 250 calories. Going forward, super-sized chocolate bars will become a thing of the past in hospital vending machines and canteens. In addition, pre-packed sandwiches with more than 450 calories and/or 5g of saturated fat per 100g will also be banned. Hospitals will be given a cash boost to help them facilitate the changes. The decision to ban fattening and sugary food products in hospitals is actually win-win for the National Health Service (NHS). These foods are major contributors to obesity and many other conditions/diseases, such as preventable diabetes, tooth decay, heart disease and cancer – all of which put enormous strain on the health service. Public Health England says hospitals have an "important role" in tackling obesity and not just dealing with the consequences.
A new report by Imperial College London in the United Kingdom, in collaboration with the World Health Organization (WHO), reveals that obesity in children is 10 times higher today than it was in 1975. Even more startling is the report’s prediction that within five years, more children will be obese than underweight. For the research, lead author Prof. Majid Ezzati, of the School of Public Health at ICL, and his team of over 1,000 researchers examined the body mass index (BMI) of almost 130 million people living in 200 countries, including 31.5 million individuals between 5 and 19 years old – making this study the largest of its kind. They found that total childhood obesity rates have risen globally by more than 10-fold in the past forty years. More specifically, in 1975, there were 5 million obese girls. In 2016, this number had risen to 50 million. A similar trend was found for boys, with 6 million obese in 1975 compared to 74 million in 2016. The researchers say that if the trend continues, there will be more obese children in the world than underweight ones by the end of 2020. Commenting on the findings, Prof. Ezzati said: “The trend predicts a generation of children and adolescents growing up obese and also malnourished. We need ways to make healthy, nutritious food more available at home and school, especially in poor families and communities, and regulations and taxes to protect children from unhealthy foods.” The findings of the study were published in The Lancet.
While it’s commonly accepted that obesity is a major public health concern in the United States, new research has uncovered two bigger threats to people’s lives: loneliness and social isolation. Presenting the findings of their two meta-analyses of studies at the 125th Annual Convention of the American Psychological Association in Washington, D.C., study co-author Julianne Holt-Lunstad, Ph.D., a professor of psychology at Brigham Young University (BYU), and colleagues revealed that loneliness and social isolation have the potential to increase people’s risk of premature death by as much as 50%. In fact, the researchers found that the risk of premature death associated with loneliness and social isolation was equal to or greater than for obesity. While people often think loneliness and social isolation are the same, there are actually notable differences between them. Social isolation, for example, is defined as a lack of contact with other people. Loneliness, on the other hand, is the feeling that a person is emotionally disconnected from other people. The bottom line being that a person can be in regular contact with other people, but still feel lonely. A 2016 Harris Poll of US adults found that 72% have felt lonely at some point in their lives, while just under a third said they feel lonely at least once a week. Prof. Holt-Lunstad said more needs to be done at a community level to tackle the loneliness epidemic being faced.
Children who have TVs in their bedrooms are more likely to be overweight than those who don’t, according to new research. Published in the International Journal of Obesity, the study by scientists from University College London analysed data from more than 12,000 children in the UK. They found that girls in particular were more likely to put on weight the longer they spent watching TV. The scientists found more than 50% of the children had TVs in their bedrooms at the age of seven. Interestingly, girls who had TVs in their bedrooms at the age of seven were 30% more likely to be overweight by the time they were 11, compared to kids who did not have TVs in their bedrooms. For boys, the risk was slightly less at 20%. While the link between TVs and being overweight isn’t fully known, the researchers believe it is due to the children getting less sleep and snacking while they are in front of their TVs. Researcher Dr Anja Heilmann said: "Our study shows there is clear link between having a TV in the bedroom as a young child and being overweight a few years later." The scientists behind the research are now calling for more studies to see if similar patterns exist with laptops and mobile phones.
Men with waists over 40 inches and women with waists over 35 inches are at greater risk of certain cancers, as well as type 2 diabetes. That’s the message to come out of a study by scientists at the International Agency for Research on Cancer (IARC), which is an arm of the World Health Organisation. According to Dr Heinz Freisling, the lead author of the study published in the British Journal of Cancer, a person’s waist measurement is as good at predicting cancer risk as their body mass index (BMI). His advice is for people to know their waistlines. “You only need to put a tape measure around your belly button. This is easy to do and can give a person an indication of whether their risk for specific cancers is increased or not – for instance pancreas or liver cancer which are known to be related to increased body fatness or obesity,” he said. Being overweight or obese is the single biggest preventable cause of cancer after smoking and is linked to 13 types of cancer, including bowel, breast and pancreas. The study combined data from about 43,000 participants who had been followed for an average of 12 years and more than 1,600 people were diagnosed with an obesity-related cancer.
While the association between a lack of exercise and an increased risk of chronic diseases, including type 2 diabetes and heart disease, is well-established, new research shows that just 14 days of physical inactivity can increase a person's risk such conditions. A study by the University of Liverpool found that young, healthy adults who switched from moderate-to-vigorous activity and then to near-sedentary behaviour for just 14 days experienced metabolic changes that could raise their risk of chronic disease and even premature death. Presenting their findings at the European Congress on Obesity 2017 in Portugal, Study leader Dr. Dan Cuthbertson and colleagues said that reducing physical activity for just 14 days led to a loss of skeletal muscle mass in the participants. However, the reduction of physical activity for 14 days also led to an increase in total body fat. Furthermore, said body fat was most likely to accumulate centrally, which the team notes is a significant risk factor for chronic disease. Current guidelines recommend that adults aged 18-64 undertake at least 150 minutes of moderate-intensity physical activity or 75 minutes of vigorous-intensity physical activity every week. However, the Centers for Disease Control and Prevention (CDC) says that fewer than 50% of adults meet these exercise recommendations. Are you doing enough exercise each week? Even just small lifestyle changes can make a big difference when it comes to your risk of chronic disease.
Despite the fact the number of people who are overweight or obese has risen over the past 30 years, fewer people are actually attempting to shed weight, according to a new study, the findings of which were published in JAMA. Around two thirds of the adult population in the United States are obese or overweight, putting them at increased risk of heart disease, stroke, diabetes, and other chronic diseases. However, new research has found that even though there has been a significant rise in the number of people who are overweight or obese since the 1980s, the percentage of U.S. adults who are trying to lose weight has fallen. For their research, study co-author Dr. Jian Zhang and her colleagues from the Georgia Southern University, analysed the data of 27,350 U.S. adults aged between 20 and 59 years. The analyses revealed that the rates of overweight and obesity increased by 13%, from 53% in 1988-1994 to 66% in 2009-2014. Furthermore, the researchers also found that the percentage of people who attempted to lose weight over the same period actually dropped by 7%, from 56% in 1988-1994 to 49% in 2009-2014. At present, people are deemed to be overweight or obese depending on their body mass index (BMI). A BMI of 25 to under 30 is considered overweight, while a BMI of 30 or above is considered obese. A healthy diet and regular physical activity are proven to help curb weight gain, which is why we should all make a conscientious effort to watch what we eat and exercise more.

South Korean women will become the first people in the world to have an average life expectancy above 90, according to a new study published in The Lancet. The study, conducted by Imperial College London and the World Health Organisation, analysed the lifespans of people living in 35 industrialised countries. In each country analysed, the average life expectancy is expected to increase by 2030 and the gap between men and women will start to close in most countries. "As recently as the turn of the century, many researchers believed that life expectancy would never surpass 90 years," said study lead author Majid Ezzati in a journal news release. Ezzati is a professor at Imperial College London's School of Public Health in England. "Our predictions of increasing life spans," he added, "highlight our public health and health care successes. However, it is important that policies to support the growing older population are in place." The biggest issue for governments, say the researchers, will be how they overcome the challenges associated with pensions and care for elderly people. Equality of life, say the researchers, is the secret to South Korea's success, with things like education and nutrition benefitting most people in the country. Furthermore, South Korea is better at dealing with hypertension and has some of the lowest obesity rates in the whole of the world. Surprisingly, Japan, which currently has the longest life expectancy for women, is expected to tumble down the rankings going forward and be overtaken by both South Korea and France. By 2030, the US will have the shortest life expectancy of all the rich countries analysed for the research.
Half of people labelled 'obese' because of their body mass index (BMI) scores are actually healthy, according to new research, bringing into question the validity of the scoring system. Scientists claim the BMI scoring system is wrongly labelling millions of people 'unhealthy' when, in fact, they are actually much healthier than their slimmer counterparts. Dr. A. Janet Tomiyama, an assistant professor in the department of Psychology at the University of California, Los Angeles, said: "Many people see obesity as a death sentence. But the data shows there are tens of millions of people who are overweight and obese and are perfectly healthy." Scientists say that BMI is being used by healthcare companies to increase premiums in some countries and that the latest findings will be "the final nail in the coffin for BMI." The problem with BMI is that it can give people false hope. For example, a person can have a 'normal' BMI, yet be at risk of disease, highlighting that it is not always an accurate predictor of future health. Prof Tomiyama and her colleagues discovered that more than 54 million Americans are being labelled as "unhealthy," even though they are not. The study - the results of which were published in the International Journal of Obesity - analysed the link between BMI and several health indicators, including blood pressure and glucose, and cholesterol and triglyceride levels. It found nearly half of Americans who are labelled 'overweight' because of their BMIs (34.4 million people) are healthy, as are 19.8 million who are considered 'obese'.
Great news for fans of spicy food as research finds a link between eating red hot chilli peppers and a longer lifespan. The study of more than 16,000 people living in the United States found that those who ate red hot chilli peppers - ranging from a single chilli to several chillies every day - had a 13% lower risk of death from all causes compared to individuals who didn't eat them. Study co-authors Mustafa Chopan and Benjamin Littenberg, both from the Robert Larner College of Medicine at the University of Vermont, recently published their findings in the journal PLOS One. While it still hasn't been determined exactly why chilli peppers might extend lifespan, the researchers believe it is likely down to capsaicin, which activities transient receptor potential (TRP) channels. Capsaicin is also where chilli peppers get their distinctive fiery flavour. There are many different types of chilli pepper, all with varying levels of heat. They are the fruits of the Capsicum plant, which belongs to the nightshade family. Capsaicin is also believed to have anti-inflammatory and/or anti-oxidant effects, as well as helping to boost the metabolism, which can help combat obesity. The team says that further study is needed to investigate the benefits of other spices and differential effects of certain chilli pepper sub-types, which "may lead to new insights into the relationships between diet and health, updated dietary recommendations, and the development of new therapies."
The New Year is here and for many of you that will mean a new exercise regime designed to get you into shape and improve your overall health. For some people, though, sticking to a disciplined program of physical exercise is one of the hardest resolutions they can make because a lack of motivation gets in the way. But now new research sheds some light on why many people, despite understanding the benefits of regular exercise, find it hard in practice to stay physically active. Researchers from the Diabetes, Endocrinology, and Obesity Branch at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), led by Alexxai V. Kravitz, focused on why obese animals also have a hard time carrying out physical activity. They found that a dysfunction in obese rodents' dopamine systems might help explain why. Mice fed on a high-fat diet started gaining significantly more weight than mice fed on a normal diet. They were also observed to have fewer movements; spend less time moving; and were slower when they did move, compared with the lean mice. Most interesting of all was that the overweight mice's changes in movements did not correlate with body weight gain. Instead, the researchers found that a deficit in striatal D2R explained the obese mice's lack of activity. "In many cases, willpower is invoked as a way to modify behavior. But if we don't understand the underlying physical basis for that behavior, it is difficult to say that willpower alone can solve it," said Kravitz.
La Clinique Turin, one of France Surgery's partners, becomes one of the first private establishments in the Paris region to install the new da Vinci Xi surgical robot. Dr. Olivier Dumonceau , a urologist surgeon of the La Clinique Turin in Paris, performed the first prostatectomy procedure in a private center in the Paris region using the new da Vinci Xi robot. This new generation of the da Vinci robotic surgical system allows for even more precise gestures for patient safety and helps obtain better intervention results. Surgeons benefit from improved 3D vision and increased movement accuracy with this new generation of surgical robot. Dr Olivier Dumonceau said: "This new generation of surgical robot marks an additional step of technology for the patient and surgeon. Our gestures are even safer, the patient can benefit from more precise surgery. We are now developing ambulatory robotic surgery for interventions that previously required several days of hospitalisation. Patient recovers faster and can leave the hospital quickly and safely. " Dr. Perrine Goyer, a digestive surgeon at the La Clinique Turin, added: "Robotic surgery offers today opportunities for minimally invasive surgery in new areas such as obesity surgery and digestive cancer for the most complex cases." Dr. Ludovic Friederich, gynecologist surgeon at the La Clinique Turin, said: "With this latest generation of machines, robotic surgery opens new perspectives for the treatment of endometriosis in very short stay with lightened suites. In particular, there is a reduction in postoperative pain." "Our development towards minimally invasive surgery and shorter hospital stays is strategic. The replacement of our previous robot with this new technology is a huge step forward. "The possibilities for interventions are now extended to pathologies as diverse as Prostatectomy, endometriosis or digestive surgery with an even higher level of result. The treatment can be performed on an outpatient basis without compromising the quality," said Stéphane Lievain, director of La Clinique Turin. La Clinique Turin carries out some 25,000 interventions per year. It features: 150 practitioners and offers complete care in surgery, medicine, dialysis and imaging (scanner, MRI and interventional radiology). Main specialties: urology, digestive, maxillofacial surgery, cardiology, ENT, orthopedics, vascular, plastic, gastroenterology, gynecology, nephrology. With a leading technical platform, it has 216 beds and places, 16 operating rooms as well as an intensive care unit in cardiology and a monitoring unit in the heart of Paris. It is regularly quoted in the health charts of the press.
A leading bariatric surgeon in the UK has urged the government to offer gastric surgery to patients regardless of their weight. According to Professor Francesco Rubino, the Chair of Bariatric and Metabolic Surgery at Kings College, thousands of type-2 diabetes patients in the UK are missing out on vital weight loss surgery because they do not meet the NHS's guidelines when it comes to weight. That's because, at present, only type-2 diabetes patients who have a BMI of over 30 are currently eligible for bariatric surgery. Rubino says that weight loss surgery is "the closest thing to a cure" and should be used more often. In the UK, there are around 3.6 million people with type-2 diabetes, which costs the NHS up to £10 billion a year to treat. However, approximately 15% of sufferers are "normal weight" and so don't qualify for weight loss surgery under the NHS's current guidelines. "The biggest barrier we have is primarily one of stigma against obesity. The vast majority of the public believes this is a cosmetic intervention and unfortunately many physicians think the same way," said Rubino. Rubino also highlighted that weight loss surgeries, which manipulate the stomach or small intestine, do not just help people lose weight, but actually influence insulin production by altering hormones in the person's gut. "More than 50% of people with type 2 diabetes can enjoy long term remission. Another 30 or 40% enjoy a major improvement," he added.
A report from the World Health Organisation (WHO) shows that the global body has added its support to countries that place a "sugar tax" on soft drinks. It's the first time the WHO has thrown its support behind taxation. Previously, it had stopped short, simply advising a lower sugar intake. Several countries, including Mexico and Hungary, already tax added sugar products, and South Africa is introducing a sugar tax next year - the only country in Africa to do so. The WHO said that incidences of obesity, diabetes and tooth decay can be lowered if people lower their consumption of "free sugars". Free sugars are all the different types of sugar people eat, except for the ones found naturally in milk and fruit. Dr Francesco Branca, nutrition director for the WHO, said that people should keep their sugar intake below 10% of their total calorie intake, and below 5% if possible. "Nutritionally, people don't need any sugar in their diet," he said. The WHO report found that raising prices by 20% or more leads to lower consumption and "improved nutrition". It also noted that government subsidies for fruit and vegetables, which inevitably lead to lower prices, can have a positive impact on the amount people consume.
