Syl, I went to the same website you did and found articles that say the opposite so how do you know what to believe? Also, my teacher who is telling us this information has been working with people for 35 years in a clinic and has witnessed the effects of soy and how when they get off the soy their symptoms improve. He has also witnessed women who are all about a high soy diet often end up with thyroid problems. I believe what he says.
