Google Dr. Kaayla T. Daniel. She wrote a book on the dangers of soy. There are tons of sites, books and testimonials on the health benefits of soy, but precious little about the possible harmful effects.
I still have not gotten a definite answer on whether or not soy is good for you. It seems that the pat answer is it's okay in moderation. I'll continue my research, but I just wanted to know if anyone had heard anything above and beyond my own limited knowledge.
