Yes, chocolate is good for you. It contains phenols, the same antioxidants found in red wine. It's the cocoa powder in chocolate that contains the phenols (so white chocolate doesn't count, that's just vanilla flavor).
The darker the chocolate, the better. Dark chocolate contains good unsaturated fats, whereas milk chocolate adds saturated fats from milk. Two-thirds of the fat in chocolate is unsaturated (good fat) stearic acid and oleic acid. Milk chocolate adds a saturated fat called palmitic acid, and as we know, saturated fats raise your cholesterol. The fats in chocolate have been found to reduce LDL levels (bad cholesterol).
Of course, don't eat three pounds of chocolate a day. We are talking about a handful. It's the sugar and calories in chocolate that we worry about. Semi-sweet is better than milk chocolate and usually contains less saturated fat. Dark, bittersweet is the best option, but most people probably can't tolerate it.
Want more antioxidant power?
Dip strawberries or cherries in dark chocolate for an antioxidant packed power snack. Now that sounds good!
