Ingestion of processed free glutamic acid (MSG) is known to produce a variety of adverse reactions in some people. These reactions, although seemingly dissimilar, are no more diverse than reactions found as side effects of certain neurological drugs. We do not know why some people experience reactions and others do not. We do not know whether MSG "causes" the condition underlying the reaction, or whether the underlying condition is simply aggravated by the ingestion of MSG. We only know that the reactions listed below are sometimes caused or exacerbated by MSG.

All forms of MSG (free glutamic acid that occurs in food as a consequence of manufacture or fermentation) cause these reactions in MSG-sensitive people. That includes MSG found in a plant "growth enhancer" called AuxiGro, and MSG found in a variety of other fertilizers and fungicides that have been approved for spraying on growing crops, including crops identified as "organic."
