I first heard about it from my mom's friend Karen, who's a vegan, and has been since she was sixteen (she's thirty-ish now). She doesn't eat any soy because she has endometriosis, which is also a disease that has to do with hormone problems. I guess soy messes with your hormones?
All I can find when I Google are topics on various PCOS message boards- which I don't find very credible. I'd rather hear it from a qualified person.
Interestingly enough, when looking on Google for a link, I've heard both good and bad things about soy.
The impression that I've gotten from Googling is that if you have a high amount of estrogen, soy's bad, but if you have a high amount of testosterone, it's okay. According to wikipedia, for men, the phytoestrogen
in soy can decrease testosterone levels for men. As for women, if you have a high risk for breast cancer, you shouldn't eat soy.
I don't know.
I have PCOS books hidden somewhere in my room. I have to get to bed because I have school in the morning, but I'll check tomorrow to see if I can find anything in any of them. I never really bothered to check, because like I said, I eat little to no soy.
That being said, my periods, since being a non-'junk-food vegetarian' have been regular for the first time in my life, my hirsutism has calmed down A LOT, I have hardly any acne, acanthosis nigricans have almost disappeared, and I've lost about 10 pounds. Soy or no soy, vegetarianism has been a blessing for me.
