Researchers at St. Michael's Hospital have shown for the first time that, in addition to weight loss, a specific low-carbohydrate diet may also reduce the risk of heart disease by 10 per cent over 10 years.

Two decades ago, Brandeis biophysicist Dan Perlman '68 and nutritionist K.C. Hayes developed the "healthy fats" blend in the Smart Balance buttery spread. Perlman has now come up with a new invention -- the parbaked coffee bean. According to Perlman, this method of roasting green coffee beans enhances the health benefits of coffee. Perlman is developing the flour milled from … [Read more...]

Consumers tend to view full-service restaurants as providing healthier, higher quality food than fast-food restaurants, but some studies have found much higher calorie, fat, and … [Read more...]

The prevalence of excess weight and obesity among adolescents and, as a result, the concomitant problems, has increased considerably in recent years. A study by the UPV/EHU has confirmed that, irrespective of the total calories consumed and the physical activity done, an excessive proportion of fat in the diet leads to a greater accumulation of fat in the abdomen. The study has … [Read more...]

Massachusetts General Hospital (MGH) investigators have developed a transgenic mouse that synthesizes both the omega-3 and omega-6 essential fatty acids within its tissues on a diet of carbohydrates or saturated fats. Called "essential" because they are necessary to maintain important bodily functions, omega fatty acids cannot naturally be synthesized by mammals and therefore … [Read more...]

A diet that combines unsaturated fats with nitrite-rich vegetables, such as olive oil and lettuce, can protect you from hypertension, suggests a new study led by King's College London. The findings, published in the journal PNAS, help to explain why some previous studies have shown that a Mediterranean diet can reduce blood pressure.

By comparing how gut microbes from human vegetarians and grass-grazing baboons digest different diets, researchers have shown that ancestral human diets, so called "paleo" diets, did not necessarily result in better appetite suppression. The study, published in mBio® the online open-access journal of the American Society for Microbiology, reveals surprising relationships … [Read more...]

Roughly 25 million Africans live with HIV, many of whom now have access to antiretroviral treatment (ART). ART has reduced the number of AIDS-related deaths greatly, but several African countries still report very high mortality rates within the first few months of treatment.
