So did I. Even if there was something real behind it the way it is written is just silly.
Sorry to ruin your blog entry. I have to agree that there may well be a comercial intrest behind it.
As far as the real science goes, there is still much debate over soy's interaction with human hormones. The whole issue has to do with molecules called phitoestogens (may not be spelled right) or plant estrogen. They have a similar structure to estrogrn so the question is weather or not they can interfere with human sex hormones. There are two competing ideas about it. One hypothesis is that the plant estrogen may act exacly like human estrogen and may interfere with fertility sexual function etc. The other idea is that the plant estrogen may bind to estrogen receptors in the body blocking the body's ability to use estrogen.
In one case the person would become more feminine. In the other the person would become more masculine. Obviosly the effect is small if it exists at all. For a time soy was thought to help with menopause induced hot flashes but the effect was not impresive. By the way, the same plant estrogen is found in other foods as well.
Personaly, I don't worry about it. I am an omnivore in the truest sense. I will eat anything, including soy. So far no food has induced a change of sexual orientation or genital shape or size. (As beens go I think soy are a little less gassy :nuke: than most.)
