The health benefits of eating fiber have long been hailed, but how much fiber should we all be eating to prevent chronic disease and premature death? A new study reveals just that… Commissioned by the World Health Organization (WHO), the research is the culmination of a meta-analysis of observational studies and clinical trials that took place over almost 40 years. The results appear in the journal The Lancet. One of the objectives of the research was to help in the development of new guidelines for dietary fiber consumption, as well as discover which carbs protect us the most against noncommunicable diseases. So how much fiber should we be eating? Well, the research found that a daily intake of 25–29 grams of fiber is ideal. People who consumed this amount of fiber each day were 15–30 percent less likely to die prematurely from any cause and had a 16–24 percent lower incidence of stroke, coronary heart disease, type 2 diabetes, and colon cancer. The researchers also say that consuming more than 29 grams of fiber per day could lead to even more health benefits. Speaking about the findings of the study, Professor Jim Mann, of the University of Otago, in New Zealand, said: “The health benefits of fiber are supported by over 100 years of research into its chemistry, physical properties, physiology, and effects on metabolism. “Fiber-rich whole foods that require chewing and retain much of their structure in the gut increase satiety and help weight control and can favorably influence lipid and glucose levels. “The breakdown of fiber in the large bowel by the resident bacteria has additional wide-ranging effects including protection from colorectal cancer.” Fiber-rich foods include vegetables, whole grains, fruit, and pulses, such as beans, peas, lentils, and chickpeas. Are you consuming enough fiber?
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.
A new study, one of the largest of its kind, suggests being the wrong weight i.e. overweight or underweight cold knock four years off a person’s life expectancy. According to the study, the findings of which were published in the Lancet Diabetes and Endocrinology journal, from the age of 40, people towards the higher end of the healthy Body Mass Index (BMI) range (a healthy BMI ranges from 18.5 to 25) had the lowest risk of dying from disease, including cancer and heart disease. In contrast, individuals who had BMI scores of less than 18.5 or more than 30 had life expectancies that were 4.4 years and 3.85 years shorter respectively. BMI scores, which are calculated by dividing a person’s weight (in kilograms) by their height (in metres squared), are still considered by health professionals to be the simplest and most accurate way to work out if someone is overweight or underweight. For the population-based cohort study, researchers analysed anonymised data on 3.6 million adults from the U.K. Clinical Practice Research Datalink (CPRD). Dr Krishnan Bhaskaran, lead author of the study, said: “The most striking thing about our findings was how widely BMI was linked to different causes of death. BMI was associated with deaths from nearly all major causes.” He added that the research reinforces the importance of maintaining a healthy body weight. Perhaps the most interesting finding is that people who have low BMI scores are at as much risk, if not more, of reducing their life expectancies.
The physical health problems associated with diabetes are well understood and publicised. For example, diabetics have an increased risk of developing cancer, kidney disorders and cardiovascular disease. But what about the mental impact of living with diabetes? It’s not something that gets a lot of attention, but the findings of a new study could see it thrust under the spotlight. That’s because the study by researchers from Finland found a worrying connection between diabetes and the risk of someone dying by suicide or alcoholism. According to the study, diabetics are more than 10 times more likely to die as a result of alcoholism – predominantly cirrhosis of the liver – and 110% more likely to commit suicide than the general population. The highest risk was seen among diabetes patients who rely on regular insulin injections to avoid serious health complications. Professor Leo Niskanen, of the University of Helsinki, who led the study, said diabetes patients who have to monitor their glucose levels and administer insulin frequently suffer tremendous mental strain. “This strain combined with the anxiety of developing serious complications like heart or kidney disease may also take their toll on psychological well-being,” he said. Is it time we started talking about the mental health implications of living with diabetes? [Related reading: Type-2 diabetes could actually be detected up to 20 years in advance, researchers say]
Some of the warning signs often associated with type-2 diabetes can be detected years before the disease is actually diagnosed, researchers say. A study found factors such as insulin resistance and elevated blood sugar levels were seen in people years prior to them developing pre-diabetes – a typical pre-cursor to the type-2 form of the disease. The authors of the Japanese study say their findings suggest that diabetes treatment should begin much earlier in life. For the study, conducted over an 11-year period, the researchers followed a group of 27,000 people who were not diabetic and aged between 30 and 50. The individuals were tracked until they either (a) got diagnosed with type-2 diabetes; (b) got diagnosed with pre-diabetes; or (c) the end of 2016 was reached. During the study, 1,067 new cases of type-2 diabetes were diagnosed. The interesting part is that these people showed warning signs, such as insulin resistance and higher fasting blood sugar levels, up to 10 years prior. Similar warning signs were also seen in those that went on to develop pre-diabetes. So, this suggests that type-2 diabetes could actually be detected up to 20 years before a diagnosis occurs. This is because people who develop type-2 diabetes usually get pre-diabetes first. Dr Hiroyuki Sagesaka, from Aizawa Hospital in Matsumoto, Japan, who led the research, said: “Because trials of prevention in people with pre-diabetes seem to be less successful over long-term follow-up, we may need to intervene much earlier than the pre-diabetes stage to prevent progression to full blown diabetes. “A much earlier intervention trail, either drug or lifestyle-related, is warranted.” [Related reading: Diabetes is actually five diseases, not two]
Have you ever received a letter from your doctor or physician and not been able to clearly understand its contents? If you have, we’ve got some positive news for you. That’s because the Academy of Medical Royal Colleges is urging doctors to do away with medical jargon in correspondence to patients and use easy to understand terms instead. For example, the academy says the term “twice daily” is much better than the often used Latin abbreviation “bd”, and says patients should ask their local hospital to follow the advice. Oftentimes, hospital doctors write letters directly to a patient’s GP and refer to the patient in the third person. However, this can lead to things being misinterpreted and even the patient being offended. The academy cites the example of a father who was praised for “manfully stepping in” when his wife could not take their daughter to an appointment because she (the wife) was too ill. Doctors are also being asked to try and soften potentially sensitive information and avoid stigmatising words. For example, “You have diabetes,” is better than “You are diabetic.” The initiative is being led by Dr Hugh Rayner, a kidney specialist, who has been writing to patients directly since 2005. He said: “The change may seem small but it has a big effect. “Writing to patients rather than about them changes the relationship between doctor and patient. “It involves them more in their care and leads to all sorts of benefits.”
Dans le monde, l’espérance de vie s’allonge, mais la mauvaise alimentation est responsable de près d’un décès sur 5. Bonne nouvelle : dans le monde, l’espérance de vie s’allonge et la mortalité infantile baisse, selon une étude coordonnée par l’Institut de mesure et d’évaluation de la santé à l’Université de Washington à Seattle (IHME), publiée vendredi, qui compile des données de 195 pays et territoires. L’étude a également exploré les causes de décès dans le monde. Allongement de la durée de vie En un demi-siècle, l’espérance de vie moyenne tous sexes confondus a augmenté de 14 ans: elle est aujourd’hui de 72,5 ans (75,3 ans chez les femmes, et 69,8 ans chez les hommes), contre 58,4 ans en 1970. C’est le Japon qui détient le record de l’espérance de vie moyenne la plus élevée, 83,9 ans pour les deux sexes combinés. La Centrafrique a la plus basse, 50,2 ans en moyenne. «Les gens vivent plus longtemps», se réjouit le Dr Christopher Murray, directeur de l’IHME. Il ajoute avoir constaté avec ses collègues au cours de la dernière décennie des «progrès importants», comme la baisse de la mortalité infantile et du paludisme. En effet, les décès d’enfants de moins de 5 ans sont passés pour la première fois en dessous de 5 millions en 2016, trois fois moins qu’il y a 50 ans (16,4 millions en 1970). Un décès sur cinq dans le monde serait lié à une mauvaise alimentation De nombreuses données de l’étude pointent toutefois les problèmes liés au mode de vie, en particulier à une mauvaise alimentation. Sur les 54,7 millions de décès constatés en 2016 dans le monde, 72% sont causés par des maladies non transmissibles (affections cardiovasculaires, diabète) souvent liées au mode de vie: alimentation, sédentarité, tabac, alcool, etc. Près d’un décès sur cinq serait provoqué par une mauvaise alimentation, en particulier celle pauvre en céréales complètes, fruits et légumes, noix et poissons. Les auteurs soulignent que parmi toutes les formes de malnutrition, les mauvaises habitudes alimentaires représentent le principal risque de mortalité. L’alimentation trop salée est par exemple associée à un peu plus de dix millions de décès (18,8%) dans le monde. Il n’est donc pas étonnant que parmi les dix principaux facteurs de risque de décès on retrouve l’obésité, un excès de cholestérol sanguin, et une glycémie (taux de sucre dans le sang) et une pression artérielle élevées. Le tabac est lui responsable d’un peu plus de 7 millions de décès.
It’s thought around one in 100 babies has genes that place them at increased risk of developing type 1, insulin-dependent diabetes. And unfortunately, at present, there is no way to prevent type 1 diabetes. But experts believe a new technique may be able to prevent high-risk babies from developing the condition. The idea is to use powdered insulin to train the immune systems of infants so that they are afforded life-long protection. Pregnant women attending maternity check-ups in Berkshire, Buckinghamshire, Milton Keynes and Oxfordshire in the UK are being asked to take part in the trial. Trial participants will be split into two groups, with half getting real insulin and the other half a placebo. Neither the participants nor the researchers will know which they received until after the trial. By spoon-feeding an infant insulin powder from six months to three years, experts hope their immune systems will be trained to tolerate insulin and prevent type 1 diabetes. A lifelong condition, type 1 diabetes is an autoimmune disease which causes insulin-producing cells in the pancreas to be destroyed. As a result, the pancreas doesn’t produce any insulin and the person's blood sugar (glucose) level becomes too high. Speaking about the trial, Dr Elizabeth Robertson, director of research at Diabetes UK, said: "This is a huge endeavour, so we would encourage women living in the South East who think they might be eligible to find out more - research like this can't happen without the incredible people who take part."

Doctors should take a person’s marital status into account when assessing their risk of heart attack and stroke, a major study has found. For the study, researchers at Keele University analysed numerous trials involving more than two million people. They found that individuals who were never married, divorced or widowed were 42% more likely to develop cardiovascular disease. They were also 42% more likely to die from heart disease and 55% more likely to die from a stroke. Risk factors such as age, sex, high cholesterol, high blood pressure, smoking, and diabetes are usually associated with cardiovascular disease. However, the findings of the new study suggest marital status should also be added to the list. Senior author, Mamas Mamas, Professor of Cardiology at Keele University, in England, said: “Our work suggests that marital status should be considered in patients with or at risk of developing cardiovascular disease, and should be used alongside more traditional cardiac risk factors to identify those patients that may be at higher risk for future cardiovascular events”. The researchers say the reason marriage could have a protective effect on cardiovascular disease is because of the additional emotional and social support that’s afforded by having a spouse. People with long-term partners are more likely to have symptoms spotted earlier and encouraged to seek medical advice as a result.
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."
Most people are familiar with the phrase, ‘an apple a day keeps the doctor away’, but what about an egg a day? New research suggests that a daily egg may reduce the risk of heart disease and stroke. Despite sometimes getting a bad press for their high cholesterol content, eggs, it seems, could help us steer clear of cardiovascular conditions, according to research published in the journal Heart. For their study, researchers from the School of Public Health at Peking University Health Science Centre in Beijing, China analysed survey data relating to more than 500,000 individuals. Of those individuals, 461,213 were free from cancer, cardiovascular disease (CVD) and diabetes at baseline. Egg consumption among the study participants was noted and the individuals were followed up with after a median period of 8.9 years. The researchers' found that individuals who usually ate about one egg per day had a 26% lower risk of experiencing hemorrhagic stroke; a 28% lower risk of death due to this type of event; and an 18% lower risk of CVD-related mortality. Current NHS guidelines in the UK relating to egg consumption state: "although eggs contain some cholesterol, the amount of saturated fat we eat has more of an effect on the amount of cholesterol in our blood than the cholesterol we get from eating eggs". So, in other words, it’s not eggs that are necessarily the problem when it comes to cholesterol, but rather how you cook them. Indeed, eggs are a great source of healthful nutrients, such as protein, vitamins, phospholipids, and carotenoids.
While a low sperm count and problems with sperm quality are huge hurdles for couples who are trying to get pregnant, a new study shows that men with low sperm counts are also at increased risk of illness. The study of 5,177 men in Italy found that those with low sperm counts were 20% more likely to have more body fat, more "bad" cholesterol and higher blood pressure – all factors that increase the risk of developing diabetes, heart disease and stroke. They were also 12 times more likely to have low testosterone levels. Dr Alberto Ferlin, from the University of Bresci, who led the study, said: "Infertile men are likely to have important co-existing health problems or risk factors that can impair quality of life and shorten their lives. "Fertility evaluation gives men the unique opportunity for health assessment and disease prevention." The study’s authors say that men with low sperm counts should be actively checked for other potential health problems, which may have a greater chance of being rectified if treated earlier. However, the authors of the study stressed that their findings did not prove that low sperm counts cause metabolic problems, merely that the two are linked in some way.
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."
A study conducted in Yorkshire, Derbyshire and Nottinghamshire in the UK has found that offering new mothers financial incentives in the form of shopping vouchers boosts breastfeeding rates. For the study, more than 10,000 mothers were offered up to £200 in shopping vouchers as an incentive to breastfeed. The vouchers could be used to buy food, household items, toys, clothes, books or DVDs in supermarkets and other shops. Breastfeeding levels are among the lowest in the world, with just 12% of new mothers in some areas feeding their six to eight week-old babies this way. However, with the voucher incentive scheme, breastfeeding rates in the areas involved rose by 6%. The women were given vouchers worth £120 if they signed declaration forms stating their babies had been breastfeed for the first six weeks of their lives. The mothers received a further £80 of vouchers if they were still breastfeeding after six months. Principal investigator Dr Clare Relton, from the University of Sheffield’s School of Health and Related Research (ScHARR), said: “Our scheme offered vouchers to mothers as a way of acknowledging the value of breastfeeding to babies and mothers and the work involved in breastfeeding. “The trial found a significant increase in breastfeeding rates in areas where the scheme was offered. “It seems that the voucher scheme helped mothers to breastfeed for longer. Mothers reported they felt rewarded for breastfeeding.” NHS guidelines say that babies should be exclusively breastfeed for at least the first six months of their lives. Babies that are breastfed have fewer health problems in their younger years and are less likely to develop conditions such as diabetes when they are older. The five-year trial was funded by research councils, medical charities and Public Health England.
A “watershed” trial involving almost 300 people has seen nearly half the participants reverse their type 2 diabetes in just five months. Trial participants followed a low-calorie diet of soups and shakes for up to five months, which led to massive weight loss. One participant, Isobel Murray, 65, who had weighed 15 stone, lost over four stone (25kg) and now no longer needs diabetes pills. "I've got my life back," she says. Prior to the trial, Isobel’s blood sugar levels were too high and her diabetes medication was being increased on a regular basis. So, she went on to the all-liquid diet for 17 weeks and gave up both cooking and shopping. She didn’t even eat meals with her husband during the trial. Following the trial, 46% of participants were in remission a year later and 86% who lost 15kg (2st 5lb) or more put their type 2 diabetes into remission. Just 4% went into remission with the other best treatments currently used. Speaking about the results of the trial, Prof Mike Lean, from Glasgow University, said: "It's hugely exciting. We now have clear evidence that weight loss of 10-15kg is enough to turn this disease (diabetes) around.” The charity Diabetes UK says the trial is a landmark and has the potential to help millions of patients. The findings of the trial, which was conducted by the universities of Newcastle and Glasgow in the UK, were published in The Lancet and presented at the International Diabetes Federation.
A leading UK-based cancer charity has warned that many people could be missing the symptoms associated with pancreatic cancer and not receiving treatment that could extend their lives as a result. Pancreatic Cancer UK says that as many as one in three adults could ignore the warning signs and symptoms of potential pancreatic cancer, simply because they don’t know what to look for. Indigestion, stomach ache, unexplained weight loss and faeces that float rather than sink in the toilet are all signs of the potentially deadly disease. At present, just one person in 10 survives longer than five years after being diagnosed with pancreatic cancer. Early detection and treatment are vital for saving lives. The charity’s survey of 4,000 people suggests many people take the symptoms for granted, with 35% of respondents saying they would not be anxious if they were suffering from a few of the signs of the disease. Speaking about the results of the survey, Pancreatic Cancer UK chief executive Alex Ford said: ““We must all be aware of the possible signs of pancreatic cancer, and of the devastating impact this disease can have, because 93% of people diagnosed will not live beyond five years”. Common symptoms of pancreatic cancer include: stomach and back ache unexplained weight loss indigestion changes to bowel habits, including floating faeces Other symptoms include: loss of appetite jaundice (yellow skin or eyes) itchy skin feeling and being sick difficulty swallowing recently diagnosed diabetes
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.
Whether you call them love handles or muffin tops, the areas of built up fat that can appear above your waistline are something that many people would love to be able to easily get rid of. A new patch developed by scientists in the US could provide the easy fix people have been looking for. The novel patch delivers fat-browning drugs directly into the areas of fat and converts "bad" white fat into "good" brown fat - not only reducing the amount of excess fat, but also lowering fasting blood glucose levels. Having too much white fat - particularly around the abdominal region - can raise the risk of several health problems, including diabetes and heart disease. So far, the patches have only been trialled on mice, but it’s hoped that they can be developed for human use in the future. Study co-leader Li Qiang, Ph.D., from the Columbia University Medical Center in New York City, said the patches could offer a great alternative to existing drugs that promote fat browning. Their non-invasive nature can reduce side effects. "The nanoparticles were designed to effectively hold the drug and then gradually collapse, releasing it into nearby tissue in a sustained way instead of spreading the drug throughout the body quickly," says study co-leader Zhen Gu, Ph.D., from the University of North Carolina at Chapel Hill and North Carolina State University in Raleigh.
A study of nearly a million UK adults has found that being married appears to be good for your health, boosting your chances of survival if you have a major heart risk factor, like high cholesterol. All of the individuals involved in the study had high blood pressure, cholesterol or diabetes and the researchers discovered the ones who were married fared much better than those who were single. Dr Paul Carter and colleagues from Aston Medical School presented the findings of their study at the British Cardiovascular Society conference. They believe that having something special in your life is what’s important, rather than simply being married. At the end of their 14-year ACALM study, the researchers found that married men and women in their 50s, 60s and 70s with high cholesterol had a 16% greater chance of being alive than their single counterparts. Dr Carter said: "We need to unpick the underlying reasons a bit more, but it appears there's something about being married that is protective, not only in patients with heart disease but also those with heart disease risk factors. "We're not saying that everyone should get married though. "We need to replicate the positive effects of marriage and use friends, family and social support networks in the same way." Dr Mike Knapton, of the British Heart Foundation, said: "The take-home message is that our social interactions, as well as medical risk factors such as high blood pressure, are important determinants of both our health and wellbeing. "Whether you are married or not, if you have any of the main risk factors for heart disease, then you can call upon loved ones to help you to manage them."
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.
People with non-O blood could be at greater risk of stroke and heart attack, research suggests. Scientists say it's because A, B and AB blood contains higher levels of a blood-clotting protein. The research, which was presented at the 4th World Congress on Acute Heart Failure, analysed studies involving 1.3m people. It found that people 15 in 1,000 people with non-O blood suffered a heart attack, compared to 14 in 1,000 people with O blood. While these figures don't sound that startling at first, when applied to a whole population the numbers become more important. It is hoped that the findings will help doctors better identify who is at risk of developing heart disease. However, Dr Mike Knapton, associate medical director at the British Heart Foundation, said the findings would not have a large impact on the current advice issued by the charity. "Most of a person's risk estimation is determined by age, genetics (family history and ethnicity) and other modifiable risk factors including diet, weight, level of physical activity, smoking, blood pressure, cholesterol and diabetes. "People with a non-O blood group type - AO, BO and AB - need to take the same steps as anyone wanting to reduce their CVD risk." So regardless of your blood type, the advice remains the same: improve your diet, weight, level of physical activity and don't smoke. In addition, manage blood pressure, cholesterol and diabetes too. There's nothing you can do about your blood group, but you can make positive lifestyle changes to reduce your risk of heart attack and stroke.
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.

People should be cautious when purchasing medications online after an investigation uncovered "widespread failings" at some Internet-based providers, the Care Quality Commission (CQC) has said. The independent regulator of health and social care in England inspected 11 internet prescription services in the country and found some "potentially presenting a significant risk to patients". Despite some providers being well-run, others were cutting corners, according to the CQC investigation. For example, two online providers - Treated.com and MD Direct - did little or no checking of patients' identities. In addition, they were guilty of inadequate prescribing and gave no assurances that the clinicians working behind the scenes had the qualifications or relevant skills for the roles they were performing. Talking to BBC Radio 5 Live, Prof Steve Field, the CQC's chief inspector of general practice, said: ""Some of these websites prescribed unlicensed medicines and - even more worryingly - medicines for diabetes, Parkinson's disease, heart disease and Lithium for bipolar disorder." The CQC has now drawn up a set of clear standards for online pharmacies. Going forward, all Internet-based providers must: verify that a patient is who they say they are, such as through a Skype check obtain a comprehensive and up-to-date medical history ensure patients truly understand what medicines they are being given seek permission to contact a patient's GP One of the biggest problems cited with antibiotics being sold online is that some people treat them like sweets. More discipline is needed if we are to prevent the so-called antibiotic apocalypse - where bacteria become resistant to more and more drugs - from happening.
By simply cooking rice the wrong way, millions of people worldwide could be endangering their lives, scientists believe. That's because rice contains traces of the poison arsenic, which stems from industrial toxins and pesticides that can remain in the soil it grows in for decades. In fact, rice contains about 10-20 times more arsenic than other cereal crops because of the way it is grown in flooded paddies. Fortunately, the way people cook rice can have a dramatic effect on the amount of arsenic that finds its way into their bodies. Chronic arsenic exposure has been linked with cancer, diabetes, heart disease and developmental problems, which is why the new research is so alarming. For the BBC TV programme “Trust Me, I’m a Doctor,” Prof Andy Meharg, from Queens University Belfast, tested how three different ways of cooking rice affected the levels of arsenic in it afterwards. In the first method, he used a ratio of two parts water to one part rice. This is the method many people use and sees the water “steamed out” during cooking. It's also the method that resulted in the most arsenic remaining in the rice. In the second method, he used five parts water to one part rice and washed off the excess water. The levels of arsenic almost halved with this method. In the third and final method, he soaked the rice overnight before cooking it. This resulted in the levels of arsenic being reduced by a whopping 80%. "The only thing I can really equate it to is smoking," said Professor Meharg. "If you take one or two cigarettes per day, your risks are going to be a lot less than if you're smoking 30 or 40 cigarettes a day. It's dose-dependent - the more you eat, the higher your risk is."
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.
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.
A study in Sweden has found that obese individuals who underwent bariatric surgery had a 34% less likelihood of developing gout - a condition that is often associated with and aggravated by being overweight. For the study, researchers analysed two groups of individuals: one which had undergone bariatric surgery and one which had followed intensive lifestyle modifications, including advice on food choices, energy intake and exercise. They found that over 26 years of follow-ups, there were 138 new cases of gout in the group that had undergone the surgery and 201 new cases in the matched, non-surgery group. Interestingly, the patients in the surgery group had higher body mass indexes; larger waist circumferences; and worse glucose and cholesterol levels. Speaking about their findings, the team, which was headed up by Lena M.S. Carlsson, MD, of the University of Gothenburg, said: "The beneficial effects of bariatric surgery are not limited to weight loss, but they extend to improvement in metabolic parameters and to lower risk of developing type 2 diabetes, cardiovascular disease, and cancer." Other studies have previously suggested that bariatric surgery can lead to lower serum uric acid levels, which are the primary cause of gout.
Researchers have found that laughter may really be the best medicine when it comes to a person's health in later life. And, according to the study led by Georgia State University, when laughter is combined with moderate exercise, not only is the mental health of older individuals improved, but also their motivation to undertake physical activity. Prior to their research, lead author Celeste Greene, from Georgia State, and colleagues noted that many seniors are reluctant to carry out physical activity because they lack motivation due mainly to the fact they don't find exercise enjoyable. That's why Greene's team set out to investigate whether combining laughter with physical activity would increase the amount of enjoyment older people get while exercising, thus increasing the likelihood of them doing more and reaping the associated health benefits. For older people, regular physical activity can improve heart health; reduce the risk of diabetes; aid weight control; improve bone health; and maintain and boost muscle strength. Greene and her team created LaughActive, a unique laughter-based exercise programme, which combines moderate-intensity physical activity with simulated laughter techniques. The research team enrolled 27 older adults in the LaughActive programme, who were all required to attend two 45-minute sessions every week for a period of 6 weeks. What they found at the end of the 6-week programme was that 96.2% of participants said that laughter was an enjoyable addition to physical activity and boosted their motivation to take part. In addition, the programme was associated with significant improvements in the mental health and aerobic endurance of the participants.
Long naps of more than an hour during the day could be a warning sign for type-2 diabetes, according to a new study by Japanese researchers. The link was discovered by the researchers at the University of Tokyo while analysing observational studies involving more than 300,000 people. Their findings will be presented at a meeting of the European Association for the Study of Diabetes in Munich. Specifically, their research found that people who napped for more than an hour during the day had a 45% greater risk of type-2 diabetes than those who didn't take daytime naps. Interestingly, no link was found with naps of less than 40 minutes. UK experts have said that individuals with undiagnosed diabetes and other long-term illnesses often feel tired during the day. However, they also said there is no evidence at present to suggest that napping during the day increases a person's risk of developing diabetes. One possible explanation is that sleep deprivation, caused by busy work schedules and/or social commitments, potentially leads to increased appetite, which in turn could increase the risk of type-2 diabetes. Commenting on the researchers' findings, Naveed Sattar, a professor of metabolic medicine at the University of Glasgow, said: "It's likely that risk factors which lead to diabetes also cause napping. This could include slightly high sugar levels, meaning napping may be an early warning sign of diabetes."
As people grow older, their brains naturally lose a certain amount of white matter. But new brain scanning research by a team from Cambridge University has found that being overweight exacerbates that loss. Published in the journal Neurobiology of Aging, the study revealed that the brains of overweight middle-aged adults appear 10 years older than those of their leaner peers. However, the greater shrinkage in the volume of white matter does not appear to affect cognitive performance. White matter is the part of the brain that transmits information, and is often referred to as "the subway of the brain" because it connects different brain regions together. Obesity has long been linked to a number of health problems, including cardiovascular disease, type 2 diabetes, and some forms of cancer, but research is increasingly showing that it may also have a negative impact on the brain. Indeed, the Cambridge researchers said that the findings from their study show we need to better understand how extra weight affects the brain. The author of the study, Lisa Ronan, from the University of Cambridge, said: “This study raises the possibility that if you are overweight or obese you may be more susceptible to diseases [linked] to age-related decline such as dementia and Alzheimer’s."
One hour of "brisk exercise" each day can offset the risk of early death for people who are desk-bound in their working lives, according to scientists. The study of physical activity - the results of which were published in The Lancet - analysed data from more than one million people to see how being inactive affects people's health. Watching TV was found to be worse than sitting at a desk. This is because of the associated habits that go with it, like snacking. However, even people who sit at a desk for eight hours a day because of their jobs can compensate by undertaking an hour of physical activity. In fact, the research found that desk-bound workers who were physically active had a significantly lower risk of death than people who weren't physically active and only sat for a few hours. At present, NHS guidelines recommend people do at least 150 minutes of exercise per week. The new research suggests that is insufficient for many. Being inactive has long been linked to conditions such as heart disease, diabetes and some cancers, and accounts for around 5.3 million deaths globally each year. For comparison, smoking accounts for around 5.1 million. Prof Ulf Ekelund, Lead author of the study, from the Norwegian School of Sports Sciences and Cambridge University, said that people don't even need to do sport or go the gym to exercise. "It’s OK doing some brisk walking, maybe in the morning, during lunchtime, after dinner in the evening. You can split it up over the day, but you need to do at least one hour," he said.
A new study has found that men are much more likely to suffer a cardiac arrest than women. In fact, around one in nine men will have their heart stop suddenly before the age of 70, compared to around one in 30 women. The study researchers said that by the age of 45, men have almost an 11% lifetime risk of sudden cardiac arrest. Women of the same age have just a 3% risk. According to Dr. Donald Lloyd-Jones, chair of preventive medicine at the Feinberg School of Medicine, in Chicago, approximately 450,000 Americans die from sudden cardiac arrest each year, and most never have any of the usual symptoms associated with a heart problem. He explained that because heart disease tends to develop earlier in men than in women, more serious screening for risk factors in the male population needs to be undertaken. Smoking, high cholesterol, high blood pressure and diabetes are all major cardiac arrest risk factors. "Know your numbers, especially your blood pressure, but also know your cholesterol or whether you have diabetes," said Dr. Lloyd-Jones. "At 50, men should also have a baseline electrocardiogram, which might reveal heart problems," he added. For the study, Dr. Lloyd-Jones and his colleagues analysed data on more than 5,200 men and women between the ages of 28 and 62 who took part in the long-running Framingham Heart Study.
The government of France is set to invest 670 million euros in setting up 12 bespoke centres for genome sequencing, which will help with the ongoing battle against cancer, diabetes and other rare illnesses. It follows the submission of a report to French Prime Minister Manuel Valls on Wednesday, in which health experts outlined recommendations for developing "personalised medicine". Recent developments in genome decoding have allowed suitable treatments to be developed for tumours that have resisted previous treatment attempts, and help patients benefit from cures for unusual diseases. Announcing the investment plans, French Health Minister Marisol Touraine said that some of the investment money will come from companies. When the first-ever DNA sequencing was started in 2003, it took over 10 years to complete at a cost of some three billion dollars. Nowadays, though, analyses of the most important of the genome can be completed in just a few days and cost as little as 1,000 euros. Experts say that DNA sequencing can uncover the disposition of individuals to certain complaints and provide insights into how they react to specific medications. The ultimate goal is to allow patients to find more suitable treatments more quickly. Google, Apple and Facebook are just some of the companies that have shown an interest in the sector, and China, the US and the UK have all already made similar investments.
Surgeons in the UK have said that the number of weight loss operations performed on the NHS each year needs to rise dramatically, so that people become healthier and the health service itself saves money. Writing recently in the British Medical Journal, the bariatric surgeons said that less than 1% of people who could benefit from weight loss surgery are getting treatment, and the numbers are actually dropping, despite rising rates of obesity and diabetes. [Related article: Mediterranean diet reduces heart attacks and strokes] The surgeons also highlighted that the UK is lagging behind its European counterparts when it comes to weight loss surgery, and that there are 2.6 million people in the country who stand to benefit from surgery. According to the surgeons, people who have stomach shrinking operations lose 25-35% of their body weight, on average, in just a year. In comparison, the average loss through diets and weight loss drugs is just 7% a year. It's thought that a quarter of adults in the UK are now classified as obese - the second highest rate in Europe behind Hungary - and this reality is putting a huge strain on NHS resources and funds. The National Institute for Health and Care Excellence (Nice) has previously indicated that surgery should be considered for severely obese people who have unsuccessfully tried all other means to lose weight.

From 1999 to 2014, rates of severe obesity among kids in the US climbed, highlighting that the issue still very much continues to plague American children today. Examining national data over the 15-year period, researchers found that a third of children in the US aged between two and 19 were overweight. They also found, more worryingly, that nearly a quarter were obese and two per cent severely obese. Lead researcher Asheley Skinner, from the Duke Clinical Research Institute in Durham, N.C., said: "Despite other recent reports, all categories of obesity have increased from 1999 to 2014, and there is no evidence of a decline in the last few years." Skinner added that there are currently 4.5 million obese kids in the US who urgently need treatment because they have a heightened risk of developing type 2 diabetes, heart disease and cancer, compared with children their age who are not obese. "Unless we make big changes on a national level, we're not going to see huge changes in obesity," Skinner said. By changing school lunches; increasing opportunities for physical activity, and allowing parents access to more healthy food options, the problem of childhood obesity can be tackled head-on, according to Skinner. The study, the results of which were published in the journal Obesity, also found that rates of obesity were higher in black and hispanic children, suggesting these groups need particular help going forward to combat the problem.
A new study has revealed that heart attack victims in the United States are becoming younger and fatter. Over the past two decades alone, the average age of people suffering the deadliest heart attacks has fallen from 64 to 60, and obesity has been implicated in 40% of the most severe, according to researchers at Cleveland Clinic, Ohio. In addition, heart attack sufferers nowadays are more likely to be smokers and people with high blood pressure, diabetes and chronic obstructive pulmonary disease (COPD), compared to 20 years ago. It's a reality that is raising alarm bells. "Lifestyle changes to reduce weight, eat right, exercise and quit smoking are critical for prevention of heart attack," said senior researcher Dr. Samir Kapadia, an an interventional cardiologist in the Cleveland Clinic Department of Cardiovascular Medicine at Cleveland Clinic. Dr. Kapadia added that the responsibility for making these lifestyle changes should be shared between the patient and their medical doctor, and the issue discussed at routine checkups. The study focused on analysing heart disease risk factors among more than 3,900 patients; all of whom had been treated for an ST-elevation myocardial infarction (STEMI). One of the most severe types of heart attack, STEMIs often result in disability or death and occur when the heart's main artery is completely blocked by plaque. The results of the study are scheduled to be presented on April 4 at the American College of Cardiology's annual meeting in Chicago.
According to a new survey, people are generally happier in their 60s as they approach the end of their seventh decade, despite many of them having at least one chronic disease. Researchers at University College London, on behalf of the Medical Research Council in the UK, followed more than 3,000 Britons since birth and monitored their health and wellbeing over the years. They found that a person's average wellbeing improved as they approached the age of 70, even though many of them were suffering from diseases such as arthritis, diabetes or hypertension. For the study, participants were asked how confident, cheerful, relaxed and useful they felt while still in their early 60s. They were then asked again aged 68 to 69. Dr Mai Stafford, programme leader at the Medical Research Council's unit for lifelong health and ageing, said that people's wellbeing definitely improved as they neared the end of their 60s, but the reasons were still unclear. She said: "We found that one in five experienced a substantial increase in wellbeing in later life, although we also found a smaller group who experienced a substantial decline. "The benefit of using a cohort study like this is that we can look at how individuals change over time. "We hope this will allow us to pinpoint which common experiences may be linked to an improvement in wellbeing in later life." So while many of us will be anxious about growing older, there appears to be a light at the end of the tunnel as we approach 70.
