A 12-year study of older adults shows how the plant-based polyphenols found in coffee, cacao, mushrooms, and red wine boost brain health and support cognition.

Using a novel algorithm, researchers find that a pro-inflammatory diet increases the risk of frailty by 16% — and that the least inflammatory diets fight this decline in physical function. 

Just 4 weeks of eating a processed-foods diet drastically impairs cognition and increases inflammation in rats — and the omega-3 fat DHA ameliorates almost all of the negative effects of this unhealthy diet.

A supplement containing a specific ketone called beta-hydroxybutyrate protects and supports brain health in overweight or obese adults, who are at increased risk of poor cognitive function with age.
