MSG is a food additive found in almost all commercially prepared and packaged food. It supercharges the taste of food, but not in the way you would think. MSG operates on the brain, fooling it into thinking food tastes really great. MSG is an excitotoxin in the brain, meaning that it over stimulates the brain causing the production of excessive amounts of dopamine. This creates a drug-like rush that provides a brief sensation of well being. It is highly addictive, causing its consumers to keep coming back for more and end up overeating. In the process, brain cells are destroyed.
Because MSG damages the brain and alters the ability of the brain to respond to the signal from the hormone leptin that satiety has occurred, it is a prime culprit in the epidemic of obesity that has everyone scratching their heads as to cause. Several research studies have shown that ingestion of MSG induces obesity in rats. In fact, when researchers want to fatten up lab rats for experiments, they feed them MSG because its effect is so predictable and rats will bulk up with regularity. MSG destroys the hard wiring in the brain of a rat like it does in the brain of a person.
