Not OP, but if we switch all our protein to soy, that could have unforeseen impacts on things like breast cancer risk due to elevated amounts of estrogen. It's why soy protein supplements are generally discouraged.

Like everything else, soy is good in moderation, and we should have a wide range of choices that aren't just soy-based.

There is no evidence that dietary soy intake changes indigenous estrogen production or estrogen blood levels in a significant manor. Quite the contrary, observational studies of humans who get high amounts of dietary soy, findings have shown either no link to breast cancer or lower rates of the disease. East Asian women consume 10x the amount of soy as the average American yet suffer from lower rates of estrogen related breast cancer.

Eating soy every day has no effect on sexual health or testosterone either.
