Four years ago, a couple of nutritionists investigating red wine decided to test some chocolate from a nearby vending machine. Since their discovery, candy companies such as Mars have sponsored scientists across the country in the pursuit of happiness and a healthful chocolate bar. In the ensuing feeding frenzy, researchers have announced that chocolate contains more antioxidants than your favorite green and orange vegetables. This past February, a university group sponsored by Mars reported that, like aspirin, chocolate thins the blood, which helps prevent heart attacks. Mars also funded a nutritionist to investigate the historical use of chocolate as a medicine, perhaps searching for additional health claims.
Scientists debate whether the chemicals in chocolate have a positive effect.
But if the candy companies have their way, your doctor might someday prescribe chocolate for your health. The chemicals responsible for the buzz about chocolate and red wine are plant compounds bearing long and cumbersome names like polyphenols, flavonoids, and cyanidins. Most scientists simply use the name phenols. Fruits and vegetables are loaded with phenols, which protect the precious seeds inside. It could be that fruits and vegetables have this effect because they contain fewer calories and fat than meat and dairy products.
