Me and my wife avoid all Soy Products and it isn't easy. Many people are allergic to Soy. Men who are not allergic but still consume Soy products can experience low testosterone and sperm count, high estrogen and gyno. This is because Soy is a natural source of estrogen. A little soy sauce won't hurt you but a large amount of soy oil or protein might be the reason that your nipples are suddenly pointy and sensitive. Got milk? Cut out the soy. I think the day will come when all is revealed but right now there are very powerful business interests promoting their soy interests. And by golly they have put soy in everything you eat almost. Read the ingredients of every product that you buy and you will be impressed that most of what you eat has soy in it.
