leave side the fact that researcher is link to soya protein busniess, I think it's reasonable to combine them because soya protein is especially rich in glutamine while whey rich in BCAA.
Although some people think soya isoflavon might work like estrogen however in fact it can be anti-estrogen when your estrogen is too high. Also it might help epi/AI caused joint dryness.
The final but not the least, it's much cheaper.

Why? I personally don't take soy, but I just think the hype surrounding it is too controversial to be telling people to stay away from it. Just my opinion though....

You can never do that, otherwise they leave out details like:

not to mention the other studies were also sponsored by Solae. Researchers can be paid to come to a certain conclusion(like what they consider to be statistically significant or not), which is why you need to read the entire study yourself.

I think 'leave aside' doesn't mean i agree with their study. My comment on soy protein base on my other readings.

Never heard any gyno or hormone problem from soy when Chinese/Japanese/Korean males having various kind of soya products everyday in different ages. It just the main protein source in eastern asia. The processed soy products (Miso, soysouce etc) make the isoflavon even more bioavaliable. Yes, we chinese are genetically different from you white guys, but i doubt that will make soy protein dangerous for you. (gyno is never a Chinese restaurant syndrome)
Finally, all studies sponsored or made by a company is doubtful; but in different degree. That's why I think you are right saying that we need to read it carefully...but at least it's much better than many 'research' made by supplements companies, when people here willingly believe those advertisement like research and spend money.
For the safety and effect on soy, there are tons of independent studies in different languages (lots in asian language). My impression on soy product is positive, same as my personal experience.
To be honest, I think the fact that bodybuilding supplement busniess has less soy protein product itself is a busniess concern. Selling more expensive whey/casein/egg protein is more benefitial for companies.
