I had heard about whey protein being better then soy. I had no idea about soy protein increasing estrogen. Definetly something athletes would want to avoid.
Its true that soy may increases estrogen. Its also true that we already produce estrogen on our own and that it is important to our health. Many of these studies contradict each other in regards to size and strength gains. Real food is cheaper, can taste way better, and is equally, if not more, effective than some cheap protein made from the by-products of milk.
People drink milk post-work out in order to consume the Whey protein that it contains. With Whey supplements, made from the by-products of milk, A person can consume adequate protein without consuming all the sugar and calories in milk. I doubt that eating a steak after every workout is cheaper that whey protein, which contains amino acids and branched chain amino acids.
Whey is also absorbed within 1 hour which is important because the body absorbs protein more efficiently up to an hour post exercise. However, some people believe soy milk can cause breast cancer, do you believe this?
I was concerned about the estrogen in soy so my husband asked his urologist if eating/drinking non-fermented soy products would be a problem for an aging man and the urologist said no. I would be concerned about the phytic acid, a nutrient inhibitor of zinc, magnesium, iron and calcium. Then I would be concerned about whether or not the soy was grown from genetically modified seeds, of which Monsanto owns 90%. I don't knowingly want to eat genetically modified products.
The substance in soy is not really in the same form that estrogen is found in the human body. The estrogen like compounds are called isoflavones and may stimulate the estrogen receptors of breast cancer cells to make them grow. In males, there have been a few small studies that reported a high soy diet reduced testosterone in males. I don't have the reference (sorry!).
Excellent article about the soy vs. whey protein debate. Interesting read for those who are into lifting and use a protein supplement in their diet.
