The false belief that soy contains estrogen capable of making men less manly is one of the things that I read. It’s absolutely fake. Plants have their own chemical compounds, but they do not impact on human cells. Now you know why they keep shouting “soyboy”. Ironically, tue amount of ormones present in modern Red meat can instead impact on that. But they don’t know. So if you like your manliness you should avoid the excess of red meat, which they seem to love.
