Re: Soy Intake May Modify Risk of Breast Cancer

 ok. What about the vast amounts of soy protein isolates, etc(GMO soy at that, found in virtually EVERYTHING? That is the type of soy consumption that I think that those who decry soy take issue with.

I do agree with the GMO part, but more and more foods are becoming GMO.  So again this is not a soy issue even though they seem to be trying to make it a soy issue.

As for soy protein isolates I would like to see the studies to back up their claims.  I ran a search under soy protein isolate on PubMed, which pulled up over 400 studies.  I am not going to go through that many so I went the first 100 as a sampling.  Out of those 100 there were only 8 human studies.  Not one of those were negative.  Two of the studies showed no negative effects on the thyroid in women and young men tested.  Two other studies showed no adverse effects on the bones, but positive benefits.  Two more studies showed anti-cancer effects by their effects on estrogen metabolites.  One study showed no effect on homocysteine or other inflammatory markers.  And the other study showed positive effects on both lipid profiles and blood pressure in humans.  So what HUMAN studies are they basing their claims on?
