Here is something I found very interesting, related to ADD. The article is written a little abrasively, so I will quote the necessary portion:
"On top of improving their diets, people should reduce (and hopefully eliminate) their overall exposure to toxins, like pharmaceuticals, hand sanitizers, corn-fed meat with nitrate salts and synthetic growth hormones, refined sugars, and other bleached white products, artificial colors, artificial flavors, the so-called "natural flavors" which are usually unnatural, artificial fats such as margarine, and the ungodly tap water. The pattern is unmistakable, and all this poisoning from all directions can not possibly be accidental."
Look into what you eat... does it match up? Do you eat foods high in MSG? Is your local water high in Fluoride?
