The Other Side of Soy
I'm sure you can do a Google or Google News search on soy and read various other articles, then you can make up your own mind. Personally, I have no opinion one way or the other unless they come out with some more conclusive research. I don't eat soy, anyway... I just don't care for it.
I don't think I have an allergy to soy, but I am going to do some more research. I may change to almonds as a snack now.
