The first data pertaining to the toxicity of processed free glutamic acid (MSG) will be found in studies dating back to the 1940s; with the first studies of glutamate-induced retinal degeneration dating from the 1950s. The first data to be noticed by the glutamate industry came in the form of a report by Robert Ho Man Kwok published in 1968 in the New England Journal of Medicine, and the study “Brain lesions, obesity, and other disturbances in mice treated with monosodium glutamate,” published in 1969 in Science.
The 1968 article was written by Dr. Robert Ho Man Kwok, a recent Chinese immigrant, describing a reaction he had after eating in a restaurant that served Northern Chinese food, and asking if anyone could suggest what the cause of his reaction might have been. That 1968 publication stimulated a number of responses from the medical community, suggesting, among other things, that Kwok’s report of “numbness, tingling, and tightness of the chest that lasted for approximately 2 hours” might have been caused by eating something with monosodium glutamate in it.
The 1969 report of brain damage was followed by five decades of research wherein it’s been demonstrated repeatedly that ingestion of processed free glutamic acid (MSG) will cause brain damage, endocrine disorders, and observable adverse reactions; that excessive amounts of free glutamic acid accumulated in inter-cellular spaces in the brain will cause brain damage; and that excessive amounts of free glutamic acid are associated with abnormalities such as addiction, stroke, epilepsy, degenerative disorders (Alzheimer's disease, ALS, and Parkinson's disease, for example), brain trauma, neuropathic pain, schizophrenia, anxiety, and depression, jointly referred to as the "Glutamate Cascade."
Since 1968, the glutamate industry has vigorously denied monosodium glutamate toxicity. Their use of scientists-for-hire, rigged research, infiltration of government agencies, control of major media, and a propaganda campaign second to none, has paid off for them as witnessed by the fact that much of the world is buying into the fiction that the toxicity of monosodium glutamate, and the toxicity of its glutamic acid are controversial.
Here we present evidence that the toxicity of monosodium glutamate and the glutamic acid contained in it are not controversial. Here we present evidence that monosodium glutamate and the glutamic acid contained in it cause brain damage, endocrine disorders, and observable adverse reactions in humans.
There really is no controversy.
