Aspartame - Did you know?

Aspartame itself doesn’t have any calories, but basically, one of its ingredients, the amino acid phenylalanine, blocks production of serotonin, a nerve chemical that, among other activities, controls food cravings. As you might well imagine, a shortage of serotonin will make your brain and body scream for the foods that create more of this brain chemical—and those are the high-calorie, carbohydrate-rich snacks that can sabotage a dieter. Obviously, the more aspartame one ingests, the more heightened the effects. Simply put, aspartame appears to muddle the brain chemistry.
