It was not about some magical supplements to take.
His book is about cleaning out your body of toxins, he emphasizes that a healthier you starts with a colon, liver and kidney cleanse, then organic only foods and pure water.
He clearly explains how this will cure and prevent disease.
The basics of the books is this. Your body creates disease you don't "catch it" and you'll be free of virtually all disease if you make your body non toxic and alkalinic.
He also does his best to put it through the head of the reader how the medical and drug community is not about health but about profit. Basically hoping to enlighten the uninformed.
It is definitely the 2nd best natural health book I've ever read. (Nutritional and Physical Degeneration being the 1st, pub 1939, http://www.mercola.com
