An NIH-funded study found a single alcohol binge can let gut bacteria leak into the blood, raising levels of bacterial endotoxins and prompting the body to produce more immune cells involved in fever, inflammation and tissue destruction.

SURVEY: Weight Watchers Tips the Scales for Heath Care Professionals (PR)
The Daily Meal, with MedPage Today and Everyday Health, surveyed nearly 1,000 physicians, clinicians, dietitians and nurse practitioners on twelve commercial weight-loss programs, ranking them on short- and long-term effectiveness and on whether professionals would recommend them.
Diet
Eat Like an Egyptian
A Journal of Archaeological Science study of hair, teeth and bones from Egyptian mummies found a mostly grain-based, largely vegetarian diet heavy in barley and wheat across roughly 3,000 years. The authors suspect legumes and vegetables were staples as well.

Fishy Diet Does Not Promote Heart Health
A Canadian Journal of Cardiology review of ten studies found Greenland Eskimos had heart disease rates similar to non-Eskimos, double the overall mortality and a life expectancy ten years shorter. The authors say the high-fat “Eskimo diet” is better labeled dangerous.
Diet
Study: Low-fat diet helps fatigue in people with MS (PR)
People with MS who followed the very low-saturated-fat, plant-based McDougall Diet for a year had much less fatigue than a control group, an OHSU trial found. MRI brain lesions and other MS measures showed no significant difference between the groups.
Diet
Consuming High-Protein Breakfasts Helps Women Maintain Glucose Control, MU Study Finds
University of Missouri researcher Heather Leidy found women controlled glucose and insulin better after high-protein breakfasts than after lower-protein or no-protein meals. Women aged 18 to 55 ate one of three sub-300-calorie meals, or only water, on four consecutive days.

"Paleo" Diet Leads to Worsening Cholesterol
Forty-four healthy adults followed a Paleo diet with circuit training for ten weeks; LDL cholesterol rose 12.5 mg/dL, total cholesterol 10.1 mg/dL and triglycerides slightly. The worst outcomes came in those healthiest at the start, and the authors say the diet may negate exercise gains.
Diet
Saturated fat intake may raise breast cancer risk
Following 337,000 women in 10 European countries for an average of 12 years, researchers found those eating the most saturated fat were 27% more likely than low-fat eaters to develop several estrogen-driven types of breast cancer.
Diet
High protein diet linked to high risk of cancer
A Cell Metabolism study found middle-aged adults eating a high-protein diet were about four times more likely to die of cancer and 74 percent more likely to die of any cause during the study. People over 65 appeared to benefit from moderate protein intake.
Diet
Cholesterol Levels Lower in Vegans
Among 1,694 people in the EPIC-Oxford study, vegans ate the most fiber and the least total and saturated fat, and had the healthiest weight of any diet group. An earlier EPIC analysis found vegans and vegetarians had 32 percent lower heart disease risk.
Diet
Omega-3 rich diet boosts brain development
An Oregon Health & Science University study found monkeys fed a diet rich in omega-3 fatty acids developed neural networks resembling those of healthy humans, while monkeys on a deficient diet had far more limited networking. DHA comes from fatty fish such as salmon, mackerel and tuna.
Diet
Study suggests whole diet approach to lower CV risk has more evidence than low-fat diets (PR)
Analysing decades of diet and heart disease trials for The American Journal of Medicine, investigators found people told to adopt a whole diet rich in fruit, vegetables, nuts and fish had greater reductions in cardiovascular death and non-fatal heart attack than those told to cut fat.
Diet
Ingredients in chocolate, tea and berries could guard against diabetes (PR)
Research from the University of East Anglia and King's College London, published in the Journal of Nutrition, links high intakes of flavones and anthocyanins - found in herbs, vegetables, berries, tea and chocolate - to lower insulin resistance and less inflammation in almost 2,000 people.
Diet
Western diet linked to Alzheimer's disease
William Grant reports that in Japan, consumption of alcohol, animal-based foods, meat and rice supply tracked Alzheimer's incidence with a 15 to 25 year lag, while in eight developing countries total energy and animal fat intake tracked it with a 15 to 20 year lag.

Diet Linked to Bacteria that Causes Inflammatory Bowel Disease
Eleven volunteers ate either an animal-based or a plant-based diet for five days in a Harvard study in Nature. The animal-based group showed an eight-fold rise in Bilophila wadsworthia, a bacterium that may cause inflammatory bowel disease; it fell three-fold on plants.
Diet
Dietary treatment shows potential in a mouse model of Alzheimer's disease
Researchers at the University of Eastern Finland fed Alzheimer's-model transgenic mice from 5 to 13 months old to test whether added nutrients boost the effect of DHA. They report that starting dietary treatment early may slow the disease's progression in mice.
Diet
Mediterranean diet associated with lower risk of peripheral artery disease (PR)
In a trial of 7,477 older adults with diabetes or several cardiovascular risk factors, both Mediterranean diets, one with extra-virgin olive oil and one with nuts, were associated with lower risk of symptomatic peripheral artery disease than low-fat diet counseling over 4.8 years.
Diet
High-protein diets, like the popular Dr. Dukan diet, increase the risk of developing kidney disease in rats (PR)
University of Granada researchers fed 20 rats a 45 percent protein or a normal diet for 12 weeks. The high-protein group lost up to 10 percent of body weight with no lipid improvement, had 88 percent less urinary citrate, more acidic urine and 22 percent heavier kidneys.
