What is an excitotoxin? These are substances, usually amino acids, which react with specialized receptors (neurons) in the brain in such a way as to lead to the destruction of certain types of brain cells. Humans lack a blood-brain barrier in the hypothalamus, which allows excitotoxins to enter the brain and cause damage. Simply put, as described in Dr. Russel Blaylock’s book, Excitotoxins: The Taste That Kills, they are exactly what they sound like: toxins that excite your brain cells to death!
No strain of rat or mice is naturally obese, so the scientists have to create them. They make these morbidly obese creatures by injecting them with monosodium glutamate (MSG) when they are first born. The MSG triples the amount of insulin the pancreas creates, causing rats to become obese. MSG creates a lesion in the hypothalamus that correlates with abnormal development, including obesity, short stature and sexual reproduction problems. MSG has also been show to kill brain cells as well as to cause nausea, vomiting, migraine headaches, depression, and heart problems. Unfortunately, MSG is often disguised under other names; thus you may not be able to detect it in a list of ingredients.
Some synonyms for MSG are “Glutamate Textured Protein” or “Glutamic Acid Yeast Extract” or “Gelatin Yeast Nutrient” or “hydrolyzed Vegetable Protein.” They hide MSG under many different names in order to fool those who catch on. Food companies learned that MSG could increase the flavor and aroma and enhance acceptability of commercial food products, so it is doubtful that they will ever quit using this brain killing additive to our food supply. Take a quick trip to your kitchen and check the pantry and the fridge. You will realize that MSG is in everything: soups, the chips, the ramen, the hamburger helper, the gravy, the salad dressings, the corn oil, the broth, and so on.
Aspartame is also an excitotoxin, and it has been shown to erode intelligence and affect short-term memory. Believe it or not, aspartame was once on a Pentagon list of bio warfare chemicals submitted to Congress! It is made from two amino acids and methanol (wood alcohol). Although test studies showed that it is extremely toxic to the brain, the government suppressed this fact, and it was officially approved as a food additive for use in soft drinks in 1983. The FDA ignored complaints of headaches, dizziness, nausea, vomiting, seizures, convulsion, blurred vision, and a multitude of other negative reactions to aspartame.
