Guest guest Posted December 23, 2003 Report Share Posted December 23, 2003 ************************* increase in protein synthesis.(1) On a side note, beside having a poor AA profile, soy intake may cause a number of health/performance problems for men, for an excellent article on the topic, with references, visit http://t-mag.com/html/body_87prote.html , or http://www.t-mag.com/nation_articles/185soy.html . -Avoid soy like the flu, and the plague ********************************* I think the dangers of soy have been overstated. I have not seen any reliable evidence that soy protein should be avoided by athletes. While soybeans themselves have poor amino acid profiles (mainly due to the lack of methionine), Supro soy protein isolate (which has methionine added) has a PDCAA of 1.0, which is equivalent to egg and whey. Thus, the amino acid profile of soy protein *isolate* is excellent. Second, the concerns regarding testosterone and performance have been overstated. It is true that in rats, genistein administration decreases testosterone concentrations. It has also been observed that there is an inverse relationship between soy intake and testosterone in Japanese men. However, the correlation in this study was extremely small. In a later study by the same researchers, soy supplementation did not alter testosterone concentrations in Japanese men. Similar results have been observed in monkeys. Krieger, M.S.
