2. Dark chocolate boosts brain power
Have a big meeting, test or dinner with the in-laws? Eating dark chocolate can give your brain a short-term boost—increasing your alertness—for two to three hours, a University of Nottingham study found. Flavanols, one of dark chocolate’s key components, dilates blood vessels, allowing more oxygen and blood to reach key areas of the brain, which can help you soldier against fatigue and the effects of aging. The study participants consumed a flavanol-rich cocoa drink, but you can eat dark chocolate by itself—or any foods high in flavanols like red wine, green tea and blueberries.
