Greater dietary fibre intake associated with lower risk of heart disease
Researchers at the University of Leeds have shown that greater dietary fibre intake is associated with a lower risk of both cardiovascular disease and coronary heart disease. Dr Victoria Burley, from the School of Food Science and Nutrition at the University of Leeds and senior author of the study, said: “It has previously been difficult to demonstrate the long-term influence of diet on heart attacks or strokes.

Red Wine Component Can Undo Some of the Harm Done by Poor Diet, Researchers Find
AUSTIN, Texas — For the first time, researchers have demonstrated that resveratrol - which is abundantly available in red wine and also found in grapes, peanuts and berries - can ease some of the negative effects on the immune system caused by a diet high in fat. "In preclinical studies, resveratrol has been shown to be beneficial in slowing the aging process and inhibiting some of the deleterious effects linked to obesity," says Christopher Jolly, associate professor in the Department of Nutritional Sciences at The University of Texas at Austin.

A brain reward gene influences food choices
Research has suggested that a particular gene in the brain's reward system contributes to overeating and obesity in adults. This same variant has now been linked to childhood obesity and tasty food choices, particularly for girls, according to a new study by Dr. Patricia Silveira and Prof. Michael Meaney of McGill University and Dr. Robert Levitan of the University of Toronto.

Obesity at age 66 predicts health at 85, study finds
Women entering their senior years with a healthy weight and waist size have a significantly better chance of reaching age 85 without chronic disease or mobility impairment, according to a nationwide health study that followed more than 36,000 women for up to 19 years. Put another way, a 66-year-old woman with a body mass index (BMI) over 30, combined with a waist circumference of about 34 inches, has increased odds of coronary and cerebrovascular disease, diabetes mellitus, certain cancers, hip fractures and arthritis over the subsequent two decades later - if she lives that long.

Lack of protein drives overeating
7 November 2013 Humans' instinctive appetite for protein is so powerful that we are driven to continue eating until we get the right amount of protein, even if it means consuming far more energy than we need, according to new research from the University of Sydney's Charles Perkins Centre. Published online in Obesity Reviews , the research shows the overriding drive for dietary protein could be a key factor in the global obesity epidemic, with individuals' total energy intake increasing as the percentage of protein in their diets decreases.

Small changes can reduce produce contamination
Cornell researchers have identified some agricultural management practices that can boost or reduce the risk of contamination in produce from two major foodborne pathogens. For example, applying manure within a year of harvesting produce boosts the odds of contaminating a field with salmonella, the biggest single killer among the foodborne microbes, report the researchers.

Fear of Predators Drives Honey Bees Away from Good Food Sources
Most of us think of honey bees as having a bucolic, pastoral existence-flying from flower to flower to collect the nectar they then turn into honey. But while they're capable of defending themselves with their painful stings, honey bees live in a world filled with danger in which predators seize them from the sky and wait to ambush them on flowers.

Indian job-guarantee scheme reduces child malnutrition
Indian job-guarantee scheme reduces child malnutrition
Babies in a rural area of India are less likely to suffer from acute malnutrition where their families are taking part in a job-guarantee programme to provide work with a guaranteed wage, an Oxford University study has found. However, the Indian government programme appears to have no effect on long-term malnutrition.

Psychological effects of genetic testing for risk of weight gain
Psychological effects of genetic testing for risk of weight gain
Obesity gene testing does not put people off weight loss and may help to reduce self-blame, according to a new study by researchers from the Health Behaviour Research Centre at UCL. Previous studies have shown that genes play a role in a person's risk of becoming overweight. One gene, called FTO, has been found to have the biggest influence so far.

Adapting to mainstream lowers diabetes risk in African-Americans
ANN ARBOR-Trying to find a produce store or a large grocer in an economically depressed neighborhood is about as easy as finding an apple in a candy store. Lack of access to good nutrition impacts racial and ethnic minorities and recent immigrants disproportionately. Poor nutrition combined with higher stress can contribute to other health problems, including type 2 diabetes.

Sleep deprivation linked to junk food cravings
Sleep deprivation linked to junk food cravings
A sleepless night makes us more likely to reach for doughnuts or pizza than for whole grains and leafy green vegetables, suggests a new study from UC Berkeley that examines the brain regions that control food choices. The findings shed new light on the link between poor sleep and obesity. Using functional magnetic resonance imaging (fMRI), UC Berkeley researchers scanned the brains of 23 healthy young adults, first after a normal night's sleep and next, after a sleepless night.
