Although virtually every food will contain some amount of glutamate, there are some foods that are rich in glutamate and can easily be combined in your favorite recipes.

*There are actually two forms of glutamate found in foods: bound and free. Since only free glutamate is effective in enhancing the flavor of food, the numbers above reflect only the amount of free glutamate for each item listed.

It does not matter whether you select glutamate-rich foods and ingredients like tomatoes, Parmesan cheese, walnuts, MSG, or soy sauce, the glutamate in each is the same.

Medical specialists have known for decades that your body does not distinguish between the glutamate found naturally in foods and that in MSG. In fact, even today’s state-of-the-art technology can’t separate them. For example, if you analyzed a plate of spaghetti, you could find out the total amount of glutamate in the dish. However, since glutamate is glutamate, there is no way to determine whether the glutamate came from tomatoes, Parmesan cheese, or MSG.
