Manufacturers claim they provide additional energy or are superior to eating regular food.
Since the major ingredients in most bars are fruit juices, sugar, milk and egg protein powders,vitamins and minerals and sometimes peanut butter and soy proteins, there is no reason to believe that they are superior to eating regular food - since you can get all of these same nutrients in a meal. The best thing about them is their convenience. They are certainly easier than preparing a meal. However, as they stand, there are no special performance enhancing characteristics about them that would make them superior to regular food. Copyright 1999 EndurePlus.
