The article you linked says they MAY have health benefits, but also says they are DEFINITELY endocrine distrupters that function exactly like normal human oestrogen in the body. There's not a single positive effect referred to in the article, other than the fact that Asians eat soy and seem to have less heart attacks than fat Americans. Also, why are you attacking the doctor and not the info?  Are you saying that there ISN'T as much oestrogen in the burger as the article states?  He doesn't make any conclusions about the health effects being entirely positive or negative, just reasonably points out it's enough to make a man grow tits.
