Question:
Asians use much MSG. Are there any studies showing neurological aberations for prolonged use.?
By neurological aberations, I mean less sexual response in older people, or trembling of extremities.
Answers:
Regarding the studies you are trying to get relating MSG to neurological conditions, this is so far what you'll find available right now:
According to lead researcher Hiroshi Ohguro, his is the first study to show that eye damage can be caused by eating food that contains MSG. A report in the New Scientist this week explains that in the study, rats were fed three different diets for six months, containing either high or moderate amounts of MSG, or none. In rats on the high-MSG diet, some retinal nerve layers thinned by as much as 75 percent, and tests that measured retinal response to light showed they could not see as well. Rats on the moderate MSG diet also had damage, to a lesser extent. The researchers found high concentrations of MSG in the vitreous fluid, which bathes the retina. MSG binds to receptors on retinal cells, destroying them and causing secondary reactions that reduce the ability of the remaining cells to relay electrical signals. This study is of course from eating MSG. I have not found a study done injecting MSG into rats or otherwise.
Today scientists know that MSG kills brain cells and causes neuroendocrine disorders in laboratory animals; and that it causes adverse reactions in humans. Scientists know that the blood brain barrier, once thought to prevent glutamate that comes from exogenous sources (eating included) from entering the brain, is not fully developed until puberty; is easily damaged by such conditions as high fever, a blow to the head, and the normal course of aging; and, in the area of the circumventricular organs, is leaky at best at any stage of life. Scientists know that a diverse number of disease conditions such as ALS, Alzheimer's disease, seizures, and stroke are associated with the glutamate cascade (Blaylock, 1994).
Scientists also understand that MSG is simply processed free glutamic acid, or processed free glutamic acid combined with sodium and that glutamic acid is a neurotransmitter that causes nerves to fire; and when present in excess quantities, causes nerves to fire until they die.
There are not studies linking other neurological conditions to MSG.
Good luck! :)
