Subject: RE: soy protein v. whey protein If you buy the research that shows that soy can act as an estrogen (I do, but I admit there are conflicting studies ) then it is no better for women than it is for men with the exception of post menopausal women.
My wife get migraine headaches before or on her period with some birth control pills. The more hormonal they are, the worse her headaches. If she eats soy protein (and I am talking high quality stuff ) she will get a migraine that will shut her down for a day. That tells me all I need to know.
Healthy women do not need extra estrogen any more than men do.
I do think it is fine in smaller amounts, like in hammer perpetum (which is soy and has a carb to protein ration of 7:1 ). They claim soy is better during, but I am not so sure. Accelorade and accel gel work so well for me and many that I wonder.
When briefly thought we might have to use soy formula to supplement our second child after my wife stopped nursing and we read everything out there on it . . . and it was scary. Especially for kids.
Like I said before, there is conflicting evidence out there and I suggest everyone make their own decisions . . . but I believe that soy is not this wonderful perfect food that it is often claimed to be. As someone will point out, there are cultures that eat a ton of soy and are healthier than us Americans (which is not hard to be ). That is a solid argument the other way. |
