SHBG and a Soy diet

Here's a couple more studies showing how great soy protein is. I have found several studies proving that it can help shrink the prostate, but all of these studies were done on animals and were inconclusive when they did the same experiments on humans. The last study was done on humans to see if soy had any effect on thyroid function, and soy really didn't have much effect on humans. The last link isn't exactly a med site or anything that legit, and it is to prove that soy protein is good for men. But if you read the first part about how "mega doses" of soy protein caused bitch tits and even discharge, it clearly proves that soy protein is estrogenic. I can't think of any other food that would give you bitch tits if you ate it in huge amounts, unless D-bol'>Dianabol is considered a food. Either way, I think soy protein is definitely estrogenic in men, but I think you have to eat it by the bucket to get the negative effects from it.
I have about 20 grams of soy protein a day just because it's so friggin' cheap, and I haven't noticed anything bad from it. I just see it as an OK (but not great) source of protein. It's being promoted as a superb source of protein just because soy is a huge cash crop just like corn, so corporations are investing money in it and that's why it's now being claimed as a miracle food. However, it's funny because I actually own some land that is being used to grow soy beans, so I refuse to talk too much shit about it.

I just read through that last study again, and even though it's supposed to promote soy intake by men, it really bashes it. It lowers testosterone and it prevents prostate cancer, but it agrivates prostate cancer if a tumor is already present.

El Mucho,,, thanks for adding to this... the study I showed was done with only 30g of Soy which shows how estrogentic it is... its drug like and has a high potiential to do harm... I love to drink Vanilla Soy milk but I won't touch it again... I think it should be banned like prohormones or at least should have a large warning on it...

Good find guys. No more veggie burgers for me!!
