Some weight loss studies show that including a little candy in your diet can make a diet easier to follow. BUT, for the best results allow no more than 100-200 calories a day for your candy treat: a small snack-size chocolate bar. The truth of the matter is CHOCOLATE can be HEALTHY! Not all chocolate has the benefits. The best for your health is solid dark chocolate. The health benefits come from the flavanoids, a phytochemical found in the cacao bean from which cocoa is produced. Dark chocolate has the highest percentage of cocoa and therefore the highest percentage of flavanoids. What does it help health wise? Heart health Blood.
