After a hard workout most of us reach for a protein shake or sports drink to refuel our bodies. Has the idea of chocolate milk ever crossed your mind? Studies like the one from the International Journal of Sports Nutrition and Exercise Metabolism have shown that the chocolate drink could be better for you. Chocolate milk has calcium, vitamin D and an optimal ratio of carbs to protein. Even better is the milk contains both casein proteins( which digest slow) and whey proteins ( which digest fast ) to give the body the best of both worlds. The best bet is to buy low fat and low sugar brands.
