MILK Good source of carbohydrates, calcium, and other nutrients. Milk does not cause cotton mouth. POP Carbonation may cause stomach upset in some athletes. Contains no nutrients. Even diet, caffeine-free pop has many added substances that need to be digested which may slow the rate of fluid absorption by the body.
Regular pop contains high amounts of sugar.
