My own thoughts based on my research into it:
Soy is a bean. Beans are fine. Soy is fine - edamame, tofu, tempeh, miso. If you have concerns about GMO then stick with organic soy.
Isolated soy protein is NOT good for you . It is found in some protein powders and some fake meats and It is as bad, if not worse for you than meat or dairy - ie it elevates IGF1 levels which are linked to cancer growth. Most studies saying soy is 'bad' were done with isolated soy protein.
Dr Greger suggests limiting soy intake to less than 3-5 servings a day. I personally believe that's too much and that a person should not rely too much on any one food. Variety is best.
That's what I've found, also. Anything in high enough quantities is dangerous. Even water can be deadly if over-consumed.
