Consuming a diet that includes flavanol-rich foods and drinks, such as tea, apples, and berries, could lead to lower blood pressure, finds a new study.

Researchers studied the effects of a 12-week exercise regimen on 148 active-duty Air Force airmen, half of whom also received a twice-daily nutrient beverage that included protein; the omega-3 fatty acid, DHA; lutein; phospholipids; vitamin D; B vitamins and other micronutrients; along with a muscle-promoting compound known as HMB. Both groups improved in physical and cognitive function, with added gains among those who regularly consumed the nutritional beverage, the team reports.

Omega-3 supplements may indeed offer cognitive benefits for children, but only after omega-3 levels reach a certain threshold, says a new review of the scientific literature.
