Aspartate and glutamate both occur naturally in your body, but you don't want to do
anything to raise your levels. The scary thing is, it's really easy to do
? Because they're both present in the modern diet, especially in the U.S. Aspartate is a component of aspartame -- the artificial sweetener known as Equal, NutraSweet and AminoSweet. It's in diet sodas, sugar-free drink mixes, and all kinds of low-calorie packaged products.
