MSG is called a "flavor enhancer" commonly added to Chinese food, canned vegetables, soups and processed meats. It is not a preservative and it has no nutritional value. It does nothing to food, but it does affect the person eating it. MSG is not a naturally occurring substance, it's man-made from glutamic acid, which is an amino acid found in all complete proteins. MSG is a major "excitotoxin" and is known to damage the part of the brain that governs many other systems in the body. Current research links MSG to neurodegenerative diseases like Alzheimer's, Huntington's, Parkinson's, and Amyotrophic Lateral Sclerosis. Children and elderly are most vulnerable to the degenerative effects of MSG. Although the Food and Drug Administration (FDA) has classified MSG as a food ingredient that is "generally recognized as safe," the use of MSG remains controversial.
Americans are now consuming an estimated 160 million pounds of MSG annually. Dr. George Schwartz, toxicologist and author says two tablespoons of MSG on a piece of bread will kill a medium-sized dog in minutes!
