There was some discussion on the Soylent thread a while back saying soy protein can cause hormonal imbalances. Not sure if I believe that to be honest.
Bodybuilders avoid it due to claims of increased oestrogen production. I haven't investigated this myself but unlikely most people are going to be adding 200+ grams of it to their diets
Not all bodybuilders do. Most, probably, but there are a number who don't believe the estrogen/soy propaganda.
If anyone's interested, I would check out this YouTuber. There are a number of them, but I really like this guy: https://www.youtube.com/watch?v=LItbM2FfSt0. The video is his six month review of veganism (he's been doing it for over a year now).
Anyway, I'm not a vegan or trying to promote the diet/lifestyle. I just want to make people aware that there are plenty of counterexamples[1] to the claims about soy ruining your hormones.
