Over 400 million people worldwide are living with type 2 diabetes, according to the World Health Organization. Yet a new study suggests the condition could be controlled and even prevented through diet alone. Publishing their findings in the journal JAMA Network Open, researchers from Tulane University in Louisiana in the United States revealed how following a diet that is low in carbohydrates can help people with unmedicated diabetes and those at risk for diabetes lower their blood sugar. For the study, the researchers recruited 150 participants and separated them into two groups: one which followed a low carb diet (less than 40 net grams of carbohydrates a day for the first 3 months and less than 60 net grams during months 3 to 6) and one which followed their usual diet. The researchers found that not only did the low carb diet group see their hemoglobin A1c, a marker for blood sugar levels, drop, they also lost weight and had lower fasting glucose levels. “The key message is that a low-carbohydrate diet, if maintained, might be a useful approach for preventing and treating Type 2 diabetes, though more research is needed,” said lead author Kirsten Dorans, assistant professor of epidemiology at Tulane University School of Public Health and Tropical Medicine. *Image by Nemanja_us from Pixabay

Taking a short walk after eating can help lower the risk of type-2 diabetes and heart problems, a new study suggests. According to the study, published in Sports Medicine, just 2 to 5 minutes of light walking after a meal can reduce blood sugar and insulin levels. Blood glucose levels spike after eating, triggering the pancreas to release insulin to control the increase and promote the storage of glucose in fat, muscle, liver and other body tissues. Over time, some people's cells develop a resistance to insulin, which can lead to blood glucose levels remaining elevated. If this persists, complications, including cardiovascular disease and nerve damage, can occur. “With standing and walking, there are contractions of your muscles” that use glucose and lower blood sugar levels, Aidan Buffey, the lead study author and a PhD student in physical education and sport sciences at the University of Limerick, told The Times. “If you can do physical activity before the glucose peak, typically 60 to 90 minutes [after eating], that is when you’re going to have the benefit of not having the glucose spike,” he said. *Image by

Its origins date back to 2737 B.C. in the Far East when the Chinese Emperor Shennong mistakenly drank water with a dead tea leaf boiled inside. Fast forward to today and people all over the world enjoy green tea as part of their diet, benefiting from the list of potential health benefits in the process. Now, new research shows that green tea may also help reduce blood sugar and gut inflammation. According to the study, published in Current Developments in Nutrition, people who regularly consume green tea have lower fasting blood sugar levels than their peers who don't. Furthermore, green tea extract was also found to decrease gut inflammation, highlighted by a decrease in stool inflammatory proteins. Senior study co-author Richard Bruno, PhD, a professor of human nutrition at The Ohio State University, said the study showed positive results after just one month. “What this tells us is that within one month we’re able to lower blood glucose in both people with metabolic syndrome and healthy people, and the lowering of blood glucose appears to be related to decreasing leaky gut and decreasing gut inflammation — regardless of health status,” he said in a statement. “This could be a simple yet powerful intervention for people with metabolic syndrome or those at risk for it. It could be a therapy to start while we continue to promote healthy lifestyle changes,” said Olivia Vaughn, a registered dietitian nutritionist at The Ohio State University Wexner Medical Center. *Image by Mirko Stödter from Pixabay

The American Heart Association (AHA) has added sleep to its cardiovascular health checklist for the first time. Sleep now joins diet, exercise, tobacco use, weight, cholesterol, blood sugar levels and blood pressure on the association's list of factors people can modify to stay healthy. The AHA published its new checklist, called “Life’s Essential 8,” in the journal Circulation on June 29. The old checklist, created in 2010, was known as “Life’s Simple 7.” “Not only is sleep health related to the other things that play a role in heart health, it seems to also be directly related to cardiovascular health itself,” says Michael Grandner, PhD, the director of the sleep and health research program at the University of Arizona College of Medicine in Tucson, who helped compile the new AHA checklist. “Sleep is changeable, and studies show that you can improve aspects of heart health just by improving sleep,” Dr. Grandner says. People who get less than six hours of good quality sleep a night are at increased risk of obesity, high blood pressure and type 2 diabetes, as well as worse mental and cognitive health, Grandner says. Likewise, those who get more than nine hours of sleep a night are also less likely to be healthy and more likely to die prematurely, he added. *Image by Wokandapix from Pixabay

For people living with type 1 diabetes, finger prick tests to check blood glucose levels are a necessary part of daily life. Without them, these individuals could experience potentially life-threatening hypoglycaemic attacks, where their blood sugar levels fall too low. But regular finger prick tests could become a thing of the past for people with type 1 diabetes thanks to an artificial pancreas being trialled in England. The technology includes a sensor under the skin that monitors blood glucose levels, a pump that automatically adjusts the amount of insulin the person needs and a smartphone app where they can input the number of carbohydrates they eat at meal times. NHS England says the artificial pancreas trial – which currently involves around 900 people – is the first nationwide test of the technology in the world. It also comes 100 years after the first diabetes patient received insulin injections. Prof Partha Kar, NHS national speciality adviser for diabetes, said: "Having machines monitor and deliver medication for diabetes patients sounds quite sci-fi like, but technology and machines are part and parcel of how we live our lives every day. "It is not very far away from the holy grail of a fully automated system, where people with type 1 diabetes can get on with their lives without worrying about glucose levels or medication." *Image by Steve Buissinne from Pixabay

Sleeping with even a small amount of light may disrupt your blood sugar and cardiovascular control, new research suggests. According to the study by scientists at Northwestern University Feinberg School of Medicine in Chicago, leaving a TV or bedside lamp on overnight is enough to the raise blood sugar and heart rates of healthy people. For the study – the results of which are published in Proceedings of the National Academy of Sciences – 20 healthy volunteers were asked to spend two nights in the university's sleep lab. On the first night, all participants slept in a very dark room. On the second, half slept with a lighting level of 100 lux, equivalent to a TV or bedside light. Each morning, the research team investigated all the volunteers’ blood sugar control. They found that people who slept in the dimly lit room on their second night had slightly worse blood sugar control than on their first night. “They thought they slept well, but your brain knows that the lights are on,” said Senior study author Dr Phyllis Zee, chief of sleep medicine at Northwestern University Feinberg School of Medicine. People who had two nights under dark conditions had little difference in their blood sugar control. Zee added: “The results from this study demonstrate that just a single night of exposure to moderate room lighting during sleep can impair glucose and cardiovascular regulation, which are risk factors for heart disease, diabetes and metabolic syndrome.” *Image by StockSnap from Pixabay

Simple educational and motivational text messages can help people with diabetes manage their blood sugar better, a new study has found. It is not only an extremely affordable and scalable measure, but one that can be applied globally. According to the six-month Chinese study, diabetes patients who received the text messages and standard care reduced their glycated hemoglobin (HbA1c ) by more than patients who just received standard care. The results showed an average reduction in HbA1c of 2 mmol/mol (0.2%) in patients who received the supportive text messages. The group that did not receive the text messages experienced an average increase in HbA1c of 1 moll/mol (0.1%). For the study, the participants were split into two groups: one that received standard diabetes care and two text messages each month thanking them for their participation, and another group that received standard care and up to six text messages per week containing information on subjects like dietary advice, physical activity, emotional support and blood glucose monitoring.  As well as actually reducing their HbA1c, the group receiving the supportive text messages also had a greater proportion of patients who achieved their HbA1C target of less than 7% (69.3% vs. 52.6% in the control group). Speaking about the findings of the study, Dr Xiqian Huo, of Beijing's Fuwai Hospital, said: “Lifestyle advice such as strict dietary control may have contributed to glycemic improvements, together with reminders to monitor blood glucose regularly. The messages were designed to provide information and motivation, and help patients set goals and manage stress.” The results of the study were presented at the annual meeting of the European Society of Cardiology on Saturday, August 31 also appear in journal Circulation: Cardiovascular Quality and Outcomes.

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.

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]

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."

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 “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.

People who are overweight or obese, despite appearing medically healthy, are still at increased risk of heart disease, experts warn. The notion that people can be ‘fat but fit’ is being challenged by research published in the European Heart Journal. According to the researchers from Imperial College London and the University of Cambridge, who studied health data relating to more than half a million people in 10 European countries, weight is still a heart disease risk factor even if someone has normal blood pressure, cholesterol and blood sugar levels. The study found that people who appeared healthy, with healthy blood pressure, cholesterol and blood sugar readings, were still 28% more likely to develop heart disease than individuals with health bodyweights. Even more at risk were people who were overweight or obese and had high blood pressure, cholesterol and blood sugar levels. Dr Ioanna Tzoulaki, from Imperial's School of Public Health, said: "I think there is no longer this concept of healthy obese. "If anything, our study shows that people with excess weight who might be classed as 'healthy' haven't yet developed an unhealthy metabolic profile. "That comes later in the timeline, then they have an event, such as a heart attack”. So the advice if you want to maintain a healthy heart is to watch your weight, even if you think you are fit.

Honey is one of the sweetest and most natural food products there is. It’s made by bees through a process of regurgitation and evaporation, then stored as a primary food source in wax honeycombs within the beehive. This is usually from where it is harvested for human consumption. But whether you’re a huge fan of honey, or will happily pass it up, there’s no denying the strong association it has long held with health benefits. First up, there’s the fact that many health experts believe that consuming honey instead of sugar results in a more gradual rise in blood sugar levels, which in turn helps to regulate your hunger levels. Honey is also recommended as a natural cough remedy by both the World Health Organisation (WHO) and the American Academy of Paediatrics. In fact, a 2007 study by Penn State College of Medicine found that honey consumption led to reduced night time coughing and improved sleep quality for children suffering with upper respiratory tract infections. If you suffer with heartburn, you may already know about honey’s effectiveness as a treatment. Experts believe its viscose nature enable it to coat the upper gastroesophageal tract, preventing stomach acid from rising. Lastly, there are honey’s antibacterial properties. It contains the protein defensin-1, which can actually kill bacteria. Furthermore, unpasteurised, raw honey can actually be used as a topical agent on open wounds because of its antibacterial qualities, but should never be used in place of a topical solution prescribed by a doctor.
