I'm not sure if you are serious, or trying to make a joke... But last I heard, consuming the Phytoestrogens in soy were found to have no measurable effect on a human male's estrogen/testosterone levels, or otherwise make them appear/act more feminine.

Sure, but I'm pretty sure the reason xenoestrogens are "bad" is because they affect the same cellular receptors as naturally occurring hormones, not because they affect estrogen/testosterone levels. Just because we've measured that something isn't the case, doesn't necessarily mean something (else) isn't happening. It could be doing something we just can't measure yet. Who knows what the long-term effects of greater phytoestrogen intake is for an individual? Or for their future offspring?

As others in this thread have alluded to, we're far from having a correct model that we can believe in with high confidence when it comes to nutrition.
