Milk Chocolate vs. Dark Chocolate Although milk chocolate may taste great, it's not nearly as good for you as dark chocolate is. This is because milk chocolate contains less of the original cocoa bean than dark chocolate does. Although milk chocolate does contain cocoa solids, it's often diluted with the addition of milk solids, sugar, and cream. Since milk chocolate does contain some cocoa solids though, its not completely void of all nutrition; however, the nutritional quality is minimal in comparison with dark chocolate, which typically has more of the original cocoa present. This is important because the more cocoa that is present, the higher the nutritional quality. Cocoa is a fabulous source of flavonoids, a special class of antioxidants that are the primary reason chocolate is now considered to be a good-for-you treat.
