A new study¹ says that older people who eat a bad diet may think better if they take cocoa extract supplements every day, but not if they eat a good diet. Cocoa extract has flavanols, which are parts of plants that may help protect cells and lower swelling. But the study writers warn that more studies are needed to prove that cocoa extract is good for brain health, and that other things, like diet, exercise, and sleep, are also important for stopping brain problems.
