This may lead to improved cognitive function and motor skills, as well as lower risk of age-related neurological disorders.
A new diet study, funded by Duke University Medical Center, aims to test the hypothesis that reducing fat intake can halt or slow diabetes progression. Participants will consume specially prepared foods with Olestra instead of real fat, allowing researchers to study a low-fat diet independently from a low-calorie diet.
Scientists have conclusively determined that European Neandertals were top-level carnivores who lived on a diet of mainly hunted animal meat. The team analyzed bone-chemistry and stable-isotope analysis to reconstruct the Neandertal diet, finding that they likely ate almost exclusively meat.

Paleontologist Bruce MacFadden analyzed fossilized horse teeth to determine their diet, revealing a combination of foods in an ancient Florida savannah-like environment. The study challenges traditional views on the relationship between tooth structure and diet.
Researchers found a strong relationship between reading nutrition labels and eating less fat. People who read labels tend to consume 30% or less of their daily calories from fat, compared to 35% for non-label readers.
A large Danish study found moderate wine consumption protects against coronary heart disease. Red wine's high antioxidant content is linked to a healthier diet, including more fruit, vegetables, and fish consumed by wine drinkers compared to beer or spirits consumers.
A large retrospective study found that poor dietary intake of animal protein in postmenopausal women is associated with an increased risk of hip fracture. In contrast, calcium and vitamin D intake had no significant association.
A study published in the American Journal of Clinical Nutrition found that African American women who lost weight on reducing diets burned less resting energy expenditure than their white counterparts. This difference was significant and may contribute to the higher prevalence of obesity among Black women in the US.
Researchers found that diets rich in fruits and vegetables reduce lipid oxidation, protecting against atherosclerosis. The study, part of the DASH clinical trial, showed participants who ate more fruits and veggies had lower breath ethane levels, indicating increased antioxidant protection.
A low-protein diet boosts thermogenesis, releasing excess energy as heat rather than storing it as fat. This results in reduced body weight gain and increased exercise motivation.

The goal is to help create a supply of nutrition professionals who can inform medical curricula and patient care.
Healthy men who used olive oil instead of saturated fats for eight weeks experienced increased triglyceride but lower LDL-cholesterol and clotting factor VII. The long-term significance of this effect on coronary mortality remains unclear.
Researchers have successfully adapted a strain of E. coli bacteria to survive on a diet that includes fluorotryptophan, a synthetic amino acid that is toxic to Earth-based life. After multiple generations, the microbes developed mutations that enabled them to cope with the artificial compound and thrive.
