Eating certain types of chocolate in small amounts can be good for you. The cocoa in chocolate contains antioxidants, which are considered “heart healthy”. Because chocolate is also high in calories and fat, it’s only a good snack if you have it in small portions. A bar of dark chocolate has a higher percentage of cocoa and is slightly lower in calories and fat than milk or white chocolate. So if you plan to eat chocolate, dark chocolate is the best choice!
