NOHA Board Member Adrienne Samuels, PhD, has carefully studied the research on "glutamic acid (found in all hydrolyzed protein products), aspartic acid (found in aspartame), and L-cysteine (currently used as a dough conditioner and proposed for use as a color preservative for fresh fruit). . . . There are . . . double-blind studies suggesting that these amino acids are safe. A review of studies relevant to the safety and toxicity of glutamic acid, however, suggest that many of them are flawed."1 For example, "in the case of MSG toxicology studies, the placebo used to test the excitotoxin glutamate is NutraSweet®, which contains the excitotoxin aspartate. It has been clearly shown in a multitude of studies that aspartate produces the identical destructive reactions on the nervous system as MSG. It would seem obvious even to the layman that you would not use a control substance to compare to a known toxin if the control contained the same class of chemical toxin. But that is exactly what is being done."2
