If you can watch Richard Schulze's Natural Healing Crusades videos on Youtube. First part, at least. The video quality is low, but the information is great.
Actually that's an understatement. The guy comes from a German background and lots of meat eating, but cured himself from heart diseases - by going vegan. One of the reasons I like him, is because of the way he talks. He has a great sense of humor, he's almost a stand up comedian!
If you haven't heard from him, you're in for treat.
