Here is one link (http://www.findarticles.com/p/articles/mi_qn4156/is_20020825/ai_n12577802) but you can find lots by googling "soy danger", and, try "neuroepidemiology soy" if I remember correctly". I used to have a whole folder of links pre-hard-drive crash. I'm allergic to soy so the growing trend to dump soy proteins and oils into everything is very scary to me.
