Your answer was as I expected, but you see my question was about "FULL FAT SOY POWDER", Not about soy products which may have been removed from the whole soybean and may be sold individually to people!
Or from products which may have been made from soy products!
The reference which you Linked to talked about isoflavones as being a problem among other things!
But the Whole Roasted Full Fat Soy powder, does not react the same way as the items which you Linked to may do so!
But as I stated, one must use it very lightly, because it is very Powerful and a very small amount goes a long way!
It is like everything else, use Moderation and some Common Sense in it's use!
The Main Problem is that most people may use TOO much and this provides for to Much Protein, which may be the Main Problem, "NOT" the excuses which they have stated to be so in the research Link!
