A compound in red wine shows promise for preventing memory loss. Well, not quite. The compound in question, resveratrol, is found in a number of common foods such as grapes, blue berries and peanuts. The study showing positive results of using resveratrol indicated a doubling of the growth of new neurons and improved blood flow. The study was done on rats. Until such a time as a study of resveratrol's neurological impact can be studied in humans, we'll just have to keep drinking wine and eating berries. As if I needed another reason to crack open a bottle.
