I remember about a decade ago talking about tofu recipes with a colleague who lifted and ate a protein heavy diet.

An older colleague heard us and warned us that eating tofu would cause you to have a surplus of estrogen and make you more feminine.

He was telling this to a guy built like a brick shithouse who had eaten tons of soy protein for the better part of a decade.

It's that same old thing, something different comes along and some people just have to parrot anything that goes against that thing, even if it's complete and utter horseshit
