I haven't found many in-depth threads on soy so I was curious. Forgive me for sounding naive but what products are pure soy? Soy milk? Also someone said whole milk has more growth hormones so I should avoid it? I have a feeling this is false. Can you confirm?
By pure soy I mean normal soy. It's green, and looks like a bean, usually inside a peapod like shell, and you eat it. It's pretty tasty steamed or boiled with some salt. In japan it's also called edamame.

But basically things with just soy-protein are much better as supplements than things make from some processing or another of soy just because you might get a lot of stuff you don't necessarily want, like extra fat (which would taste better from other foods) etc. Also personally I find soy milk tastes terrible compared to something delicious to me like skim milk, or even in general, and other stuff made with soy, like tofu etc also doesn't taste as good as something made with just soy protein isolates or even just the plain, normal soy bean used as a normal vegetable.
And on the milk, seriously, use the search function

there's a thread on that specific question right on the same page as this thread:
http://www.americanparkour.com/component/option,com_smf/Itemid,159/topic,17373.msg202346/#msg202346and the answer is that no, that's a myth, there is no risk of getting strange hormonal effects from drinking milk, at all, as I explain in that thread.
