MSG-sensitivity is a term used by people who react adversely to “monosodium glutamate” and/or any other ingredient that contains processed free glutamic acid (MSG).
As used here, an “adverse reaction” is an unpleasant reaction that can be seen or felt by the affected person or an observer. Skin rash, nausea, migraine headache, heart irregularities, seizures, and depression are examples of adverse reactions that have been reported following ingestion of MSG. Each is a visible or observable reaction. When caused by MSG, each can be traced back to recent exposure to MSG.
Gross obesity, stunted growth, reproductive disorders, learning disabilities, behavior disorders, and retinal degeneration (possibly leading to blindness) are not classified as “adverse reactions.” When caused by MSG, their roots lie in the destruction of brain cells, possibly years before gross obesity, stunted growth, reproductive disorders, 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. Similarly, researchers have confirmed that when MSG is consumed by infant animals, neonates, and even fetuses, the brain lesions are followed by neuroendocrine disorders such as obesity, stunted growth, and reproductive disorders. (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.)
A third area of concern encompasses a number of pathological conditions such as addiction, stroke, epilepsy, brain trauma, multiple sclerosis, neuropathic pain, AIDS dementia, schizophrenia, anxiety, depression, and degenerative disorders such as Parkinson’s disease, Alzheimer’s disease, Huntington’s disease, and amyotrophic lateral sclerosis (ALS). All are known to be affected by free glutamic acid. Whether ingestion of processed free glutamic acid (MSG) plays a role in causing or exacerbating these conditions is not clear. Because glutamic acid is involved in all of them, this conglomeration of pathological conditions is often referred to as the glutamate cascade.
