soy protein and sex hormones

[sebastien]

It appears that soy increases oestrogen level because of isoflavone presence.

What about soy protein ???
Does it increase oestrogene level? Does it decreases testosterone level ?

Thanks

Please read this post which I responded to the other day-

But to answer your question, yes the protein does contain phyto-estrogens.

I would highly recommend steering well clear of all soy products for countless reasons.

Soy protein contains phytoestrogen, a weak estrogen. For this reason I never use it.
