That was propaganda released by the meat industry. It came out after the study was released that the estrogen from soy was BS.
Phytoestrogens from plants like soy are good for you.
You might want to avoid soy because much of it is gmo, but almost all goes to feed animals, who are then eaten by humans.
You consume those gmo phytoestrogens in the flesh and breast milk of a female cow who excretes estrogen.
A man would get man boobs more from eating too many animal products then from eating tofu.
