Excitotoxins are food additives that can stimulate nerve cells in the brain to death. The most common excitotoxins in the diet are MSG and aspartame. MSG, in particular, is present in almost all processed foods, but is often called by different names. It can even be in foods labelled 'No MSG'.

The author, a neurologist, believes that excitotoxins may cause or contribute to a number of diseases, including Alzheimer's and brain tumors. Children and the elderly are particularly vulnerable to brain damage from excitotoxins, but adults often experience times when the brain's defenses are down, too.

The mechanisms through which excotoxins affect the brain, and the resulting health dangers, are explained in detail. A list of ingredients/additives to avoid is included. This book is especially important if you have children or an elderly relative to care for.
