RE: Re: Tofu linked to mental deficiency

Ya'd think that if soy caused prostate cancer, you'd be see a high incidence

The references to those studies I have read report that the ALA in the diets

of those studied came from red meat, rather than soy or other plant source.

I guess the jury is still out on soy and flax. But there are certainly

other factors at work in developing prostate cancer.
