Collected Reports of Adverse Reactions to MSG Ingestion 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) 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."

When caused by MSG, their roots lie in the destruction of brain cells, possibly years before gross obesity, stunted growth, learning disabilities, behavior disorders, and/or retinal degeneration are first observed. Research confirming that MSG consumed by laboratory animals causes brain lesions in the area of the hypothalamus has been replicated many times. Research that has claimed to find that MSG is "safe" has always been seriously flawed; and has always been financed, directly or indirectly, by the glutamate industry. Obesity, reproductive disorders, and learning impairment, that sometimes become obvious only after puberty, may have their origins in neuroendocrine dysfunction caused by exposure of infants and small children to MSG.
