Protein and the increase in estogen

[Smokescreen]

Since protein powder contains Soy. And I take 1 shake of Protein powder per day (not sure if anyone here does the same). Does that mean that I'm increasing estrogen?

there are many theories about soy as an estrogen mimic. i read somewhere it could even act like nolvadex, and occupy your estrogen receptors and render them useless without activating them. which would be AWSOME.

i'm not sure if that is even true or not, so i just completely avoid soy, and go with whey. are you lactose intolerant? i like Optimum Nutrition Whey because they have lactase enzyme mixed in to help you digest it better and avoid stomach issues

Yeah but all proteins (regardless if its whey or not) has soy in it. It's what makes it instanitized. Did I spell that correctly? LOL

Nolvadex kills libido in most. Me too.

In some studies it seems that there is an affect in animals, but not really in humans.

here is one done on humans that didnt really have an affect

Clinical Science (2001) 100, 613-618 - J. H. Mitchell and others - Phytoestrogens and reproductive health

here is another one saying it is fine for guys

heres a study about soy and its affect on the brain - done in rats though, so probably not so applicable.

Dietary soy phytoestrogen effects on brain structure and aro... : NeuroReport

this one also done in rats talks about plasma test levels being affected - again in rats :\

Dietary soy-phytoestrogens decrease testosterone levels and prostate weight without altering LH, prostate 5alpha-reductase or testicular steroidogenic acute regulatory peptide levels in adult male Sprague-Dawley rats

fuck i just checked my whey jug and it says it has soy lechtins. i hope the affects are negligible lol

If you do a search on the web. You will see that there is whey protein WITHOUT soy. But I believe it costs a bit more.

i doubt the small amounts of soy are really gonna have any noticable effect on your estro levels. soy is a known phyto-estrogen, but its just a big controversy if it has any real effects. theyres really so much shit out there that contains chemical estrogens too its rediculous and un-avoidable. read need2's thread about Understanding Gynocomastia. he explains all this

Estrogen metabolism is quite complex. Phytoestrogens are present in many plant sources and promote healthy estrogen metabolism.
