Dr. John R. Lee: All isoflavones probably have beneficial effects and that's why beans, garlic, and many other foods are healthy. Even the whites on the inside of the orange peel. Don't overdo it on the soy. The people around the world that eat soy actually eat fermented soy products and not the soybean itself. Also, they almost always eat it with seaweed and a protein because soy chelates out minerals and blocks protein absorption. Dr. John Lee has explored natural progesterones for many years. He writes extensively and has been on several online chats. This came from powersurge.com Remember we are NOT Doctors and have NO medical training.
