Freefaller, its simply not hog wash, its chemically COMPLETELY DIFFERENT with one tiny bit that binds to the receptor thats the same, its the receptor side that gives them commonality and made some idiot somewhere decide to call it phyto-estrogen, its simply not, it doesn't react anywhere else in the body as estrogen.
THe reasons some people get the man boobs when they take soya, is most people to date don't take a lot of soya in terms of protein shakes, its never been hugely popular as such. THe other sources of soya though mostly tend to be very high in fat. Tofu has more fat that protein, soya milk has a lot of fat in, the reason most people who get fat when they eat lots of excess fat on an overly fatty diet, is the fat, not the phyto-estrogen.
IF they'd just called it phyto-female-hormone-blocker , no one would even consider it as potentially bad. If someone had named water, "makes you really fat" , and someone got really fat, eating 5 pizza's a day, they'd still think it was the "makes you really fat" that was making them really fat.
Again, the reason it can slow down/change period cycles is the pituitary gland is completely full of receptors, the pill uses excess estrogen so all the estrogen can bind to the receptors and tell the gland to not release an egg that month.
As we go on more and more, and more and more studies show no estrogenic effects, no increase in estrogen(infact the opposite) no strange weight gain and no problems in the slightest. From 20 years ago when someone put phytro-estrogen and his stupidity together and claimed a problem that turned into a massive myth with no proof. As more and more studies finally get done on it, they constantly show no problem at all. Even with the complete lack of proof of problems, the guy in the first article, from past assumptions, still believes higher levels will somehow change this. Because if you eat X amount and get a 0% increase in estrogen, times X amount by 50, and times 0% change, by 50, you still end up with a 0% change.
There are other problems with soya, such as simply not being the best ever protein, though its cheap and readily available, but estrogen is not one of them.
Thanks for that
Didn't mean to confuse or neglect soy protein as a useful supplement. It's something I know little about but had heard a few things about hence my providing of the links.
No worries, I typed a reply, before your reply
Its a fairly commonly held idea, and I've yet to see a single shred of proof. IT was really a case of assumption of something bad, and entirely no scientific data, good or bad, for sooo long. Its very strange there was no real research done into it for so long, but we finally see a few studies and all of them show its simply not a problem. Anecdotal evidence, like Freefallers, what effects did they have exactly, man boobs? What were they taking, what were the eating, to get man boobs, estrogen overload or not, you'd need to be eating enough to put on fat, so eating too much basically. So where should the fat have gone, were they weight lifters? Having higher testosterone levels automatically leads to higher estrogen levels. Testosterone is turned, in the body, into estrogen, the more testosterone you have, the more estrogen, though you can increase the ratio and slow down the conversion rate to do so, you will still increase estrogen, thats simply how the body works. Theres millions of things that could cause it, not least taking steroids, even more so when stopping them.
