I have been browsing this section a little and noticed alot of you bashing soy protein as being a girly protein source and that it elevates estrogen. Some of the latest research coming out proves that this is the furthest thing from the truth. While you should, of course, still vary your sources of protein to benefit from a wide range of amino acids, soy isolate supplementation is an excellent addition to a bodybuilders diet and here is why....
Bodybuilding and Athletic Supplementation Description
Soy protein is quickly again becoming popular amongst the bodybuilding community. The reason RESEARCH! Here is what research has discovered about soy isolate.
1. Soy fights cancer and has anti-estrogenic effects.
2. Soy has the highest amount of BCAA, glutamine, and arginine.
3. Soy may raise the level of endogenous production of thyroxin, which in turns speeds up metabolism.
4. Daidzein, one of soy's isoflavones, may raise the level of testosterone and growth hormone.
5. A diet rich in soy decreased the chance of heart disease.
Soy protein is considered a must in a bodybuilders diet. Due to extreme low cost, bodybuilders experience great gains in muscle mass and decrease in body fat.
Men and the Effects of Soy Supplementation
If you have been sold on the theory that soy increased estrogen you might want to reconsider. Alex Rogers has always believed that moderate use of soy isolate can actually increase testosterone, not raise estrogen. He may be correct.
Wake Forest University Baptist Medical Center held a study to determine what will happen to men when they eat a diet rich in soy isoflavones (naturally occurring plant estrogen), especially soy supplements. It was noted that patterns of aggression and social behavior were influenced.
The study which lasted 15 months divided male monkeys into 3 groups. Each group was fed different types and amounts of protein. The 125 mg of isoflavones used in this study is higher than what is consumed by Asians who eat a soy-heavy diet, but comparable to levels found in dietary supplements in the US.
Group # 1 was given 125 mg of isoflavones daily.
Group # 2 was given 62.5 mg of isoflavones daily.
Group # 3 received protein from milk and animal sources.
In the monkeys that were fed higher amounts of isoflavones, intense aggressive and submissive behaviors were elevated
When asked why he though this was so, Alex said that the soy probably increased the levels of testosterone in the monkeys. He said it would be interesting to see if any of the monkeys gained lean body mass.
This study has been published in the scientific journal Hormones and Behavior.
