Many people recognise monosodium glutamate (MSG) as the additive used, for example, in some Chinese and Japanese food, but few know what it is, let alone what its effects on the body are.  Now a new report focuses on how monosodium glutamate may be just one of the causes of the Slow Poisoning of America.

In fact, MSG (which is often disguised by names like "hydrolyzed vegetable protein" or "HVP", "yeast extract" or "autolyzed proteins") is, like aspartame, a member of the group of chemicals known as "excitotoxins" (the clue is in the name!). These toxic compounds are known to interfere with brain chemistry and have been implicated in many neurological diseases, such as brain cancers, MS, fibromyalgia, depression and hyperactivity (ADHD). In fact, they overexcite brain cells to the point of cell damage and even cell death.

MSG has also been linked to obesity and, indeed, many products that contain MSG now also contain horrific chemicals like "high fructose corn syrup" (whose purpose is to make you chemically addicted to the food in the same way as sugar).
