A South American tribe living in near-total isolation with no Western dietary influences showed no increase in average blood pressure from age one to age 60, according to a study led by researchers at Johns Hopkins Bloomberg School of Public Health. In comparison, a nearby tribe whose diet includes some processed foods and salt did

Adding highly refined fiber to processed foods could have negative effects on human health, such as promoting liver cancer, according to a new study by researchers at Georgia State University and the University of Toledo. Accumulating evidence demonstrates consumption of whole foods naturally rich in fiber confers an array of health benefits. This, combined with

New research suggests that higher-level brain functions have a major role in losing weight. In a study among 24 participants at a weight-loss clinic, those who achieved greatest success in terms of weight loss demonstrated more activity in the brain regions of the lateral prefrontal cortex associated with self-control. The results of the study were

Obese mothers who lose weight through bariatric surgery can have safer deliveries. The positive effects are many, including fewer caesarean sections, infections, tears and haemorrhages, and fewer cases of post-term delivery or uterine inertia. This according to an observational study by researchers at Karolinska Institutet in Sweden published in PLOS Medicine. Today, more than one

Powdered protein supplements are one of the most commonly consumed nutritional supplements, whether by professional athletes or amateurs, even by those who use them for aesthetic purposes instead of sporting ones. This study, led by a researcher from the Area of Human Motility and Sporting Performance at the University of Seville, has analysed the quality

An international research team led by the University of California, Irvine has identified a system of communication networks that exists among organs and tissues that regulate metabolism. Findings from their study provide, for the first time, a detailed “atlas” illustrating how the body creates and uses energy, and how imbalances in the networks may impact

It doesn’t matter if it’s rye, oats, or wheat. As long as it is wholegrain, it can prevent type 2 diabetes. This is the finding of a new study from researchers at Chalmers University of Technology, Sweden, and the Danish Cancer Society Research Center. The comprehensive study is a strong confirmation of previous research findings

Recommendations for a high quality diet to avoid cardiovascular disease were developed in high-income countries two to three decades ago. They don’t consider other parts of the world or how diets have changed. Now scientists of the Population Health Research Institute (PHRI) of McMaster University and Hamilton Health Sciences are using research from several large

A sedentary lifestyle combined with a diet dominated by processed foods has widely resulted in a range of conditions including diabetes, obesity, and high blood pressure, which are known collectively as metabolic syndrome. Although many insights into the causes of metabolic syndrome have been made, much remains to be understood about the complex interplay among

An international team of researchers has uncovered a destructive mechanism at the molecular level that causes a well-known phenomenon associated with obesity, called leptin resistance. They found that mice fed a high-fat diet produce an enzyme named MMP-2 that clips receptors for the hormone leptin from the surface of neuronal cells in the hypothalamus. This

Saliva is crucial for tasting and digesting food, but scientists have now found that it may have another, more subtle role. Salivary proteins could be part of a feedback loop that influences how food tastes to people — and by extension, what foods they’re willing to eat. The researchers hope that, one day, their findings

Lipid droplets: they were long thought of merely as the formless blobs of fat out of which spare tires and muffin tops were made. But these days, they’re “a really hot area of research,” says Michael Welte, professor and chair of biology at the University of Rochester. That’s in part because lipid droplets have been

Diet modification can be a vital step to prevent cardiovascular disease. While various biological, economical, physical, social and psychological factors influence food choices, interventions targeting these factors can lead to meaningful improvements in long-term eating habits, according to a review paper published today in the Journal of the American College of Cardiology. Research has consistently

With increasing efforts being made to address the current global obesity epidemic, wearable devices and mobile health (“mHealth”) technology have emerged as promising tools for promoting physical activity. However, current literature seems to indicate that these new technologies may serve best as part of a larger overall health plan, rather than working alone to encourage

A newly published study by researchers from the University of Colorado School of Medicine has identified a potential therapeutic target for treating obesity and diabetes. The scientists studied the biological function of an epigenetic modifier known as histone deacetylase 11 (HDAC11), and determined that deleting it in mice stimulates the formation of brown adipose tissue.

Taking multivitamin and mineral supplements does not prevent heart attacks, strokes or cardiovascular death, according to a new analysis of 18 studies published in Circulation: Cardiovascular Quality and Outcomes, an American Heart Association journal. “We meticulously evaluated the body of scientific evidence,” said study lead author Joonseok Kim, M.D., assistant professor of cardiology in the

The importance of the human brown adipose tissue (BAT) has become clearer during the past ten years. Using positron emission tomography, PET, it was shown that adult humans have functional BAT. Coldness is an effective activator of the BAT metabolic function but, in rodents, eating has the same effect. Now, the researchers at Turku PET

New research in The FASEB Journal explored why a group of young, healthy adults residing at high altitude lost muscle mass while severely underfed and consuming the same high-protein diet that preserved muscle during weight loss at sea level. A team led by Stefan M. Pasiakos, PhD, a nutritional physiologist at the U.S. Army Research

Managing type 1diabetes during the first two decades of life is challenging. Insulin requirements change along with the stages of life — childhood, puberty, young adulthood, and beyond. But a 20-year longitudinal study conducted by researchers from Joslin Diabetes Center and Harvard Medical School identifies clear predictors of rising A1C levels in young persons, as

The balance between omega-6 and omega-3 fatty acids in the tissues of female mammals, which previous research has suggested can impact the incidence of obesity in their offspring, appears to do so through its effect on the microbial population of the infant’s gastrointestinal tract. In the open-access journal Microbiome, a team of investigators from Massachusetts
