Researchers at North Carolina State University found that food-based lessons for Head Start preschoolers helped children learn science and grow their vocabulary. The program used seed activities, simple recipes and teacher training in three counties.
A clinical trial in people aged 65 and over found that extra protein from whey capsules did not increase muscle strength after 24 weeks. Researchers say resistance exercise remains the most reliable way to improve strength.
Two research papers report that adding wheat fiber to the diet protects mice from intestinal inflammation. Gut bacteria release polyphenols from the fiber that reduce inflammation, and authors suggest whole-grain foods may lower IBD risk.
An animal study using newborn pigs found that formulas high in medium-chain fats from coconut oil led to faster liver fat accumulation than formulas with long-chain animal fats. Researchers say this finding is not a reason to stop using formula.
