You'll have to forgive me if I continue to use the muscle-building soy PI I've been consuming over the last 10 months... with no ill effects.
I too have eaten a diet of 90%+ meat. I certainly didn't feel as good on that as I do now, and I really couldn't advocate it in good conscience.
Us males have enough that can go wrong internally, cancer-wise, without adding undigested meat buildup into the mix.
And as for legumes etc: if they were honestly as bad for the human body as you make out, I doubt they would be sold and consumed in such abundance, let alone have diet plans based around them still in circulation.
