No, this is nothing but media driven misinformation. For men and boys, the phytoestrogens in soy do not appear to have any effect on hormone levels and have not been shown to affect sexual development or fertility.
Isoflavones are dissimilar from estrogen in many ways. Unlike estrogen, isloflavones are tissue selective and can have estrogen-like effects in some tissue but either no effects or antiestrogenic effects in other tissues. Isoflavones are referred to as phytoestrogens because they bind to estrogen receptors and exert estrogen like effects under some conditions. However, the ability of a chemical to bind to hormone receptors, such as the estrogen receptor, won't tell you much about potency or any resulting biological activity.
Women predisposed to breast cancer should not consume soy either because phytoestrogens promote cancer cell growth.
Yes, it is a commonly accepted view that food containing isoflavones, specifically genistein, mimics estrogen and accelerates breast cancer in susceptible women. (Those already with cancer that are estrogen receptor positive). This view, however, ignores Asian women who eat a diet heavy in soybean based foods, and therefore have a higher exposure to genistein, but do not share this same experience with breast cancer.
In Okinawa, soy makes up about 12% of the diet of elder Okinawans yet they experience 80 percent less breast cancer and prostate cancer, and less than half the ovarian cancer and colon cancer, than we do in north America. Go figure.
There are phytoestrogens in soy. Can’t imagine why you’d dispute this.
And who pays for the “studies” at universities? Soy companies, pharmaceutical companies — all looking for an outcome.
As I posted earlier, Isoflavones and estrogen are very different. Confusing them causes much of the unnecessary fear regarding soy.
Having an education in the life sciences will help as will lots of training outside the classroom. But research is so specialized today that it becomes more and more challenging to separate the legitimate from those looking for a desired outcome. This one isn't that tough, however. With what we know to be true at this time, soy isn't responsible for the many maladies the alarmists accuse it of.
Maybe raw soy sprouts is fine as a vegetable, but concentrated in soy milk has caused breast growth in black military men I know and told me to stay away
As for me, any kind of vegetable based protein is bad for me due to my blood disorder worsening with beans , lentilles and soy
It’s just that I saw it first-hand with my relative, manboobs and all. Every symptom claimed in the article and the video at the link, he had. And he died too young, after living in misery on a heavily soy vegan diet. So there’s that. And having seen it and mourned it, you’re not going to convince me otherwise, so stop trying.
