Weightlifting In The Gym - SoyEverybody knows that Soy is a great source of protein, while being a product that promotes good health. Here is more: Soy-based foods contain substances called isofavoines, which appear to protect against both cardiovascular disease and cancer. Soy isolfavones are structurally similar to estrogen and can displace estrogen in the body. That makes them protective, since breast cancer in women and prostate cancer in men are related to elevated estrogen levels. Recent research also confirms that eating soy leads to drop in serum testosterone and lessened oxidation of low-density-lipoprotein cholesterol. These two effect are thought to explain protection against the onset of prostate cancer. The drop in testosterone may at first appear problematic to bodybuilders, who are aware that it's a major anabolic hormone for building muscle. But the results of a study in rats showed the increase of serum androgens, such as testosterone. However, one exception is that the soy products inhibited an enzyme called 5-alpha reducatase, which converts testosterone ito dihydro-testosterone, or DHT. While DHT is linked to male pattern baldness, acne and prostate enlargement and cancer, ti does perform server essential functions in the body. For example, male sex organs don't develop without DHT. Soy appears to be a natural inhibitor of DHT syntheses and bodybuilders over 40 may want to consider it because of the protection it offers against cancer and cardiovascular disease. ![]() The key is moderation, since too much soy will not only lower testosterone levels but may also act like an estrogen and cause the negative side effects associated with it in me. About 25 grams of soy protein a dat, or no more than 50 milligrams of isofavones will do it. Meanwhile a different study based on mice, concluded that a primary soy isofavone called genistein helps prevent fat gain. Frequently linked to increased deposits of body fat, estrogen also - paradoxically enough - prevents excess fat tissues by inhibiting lipoprotein lipase, an enzyme that increases triglyceride (fat) stores in fat cells, or lipocytes. Genistein has about 1/110,l000 the estrogenic effect of estroge itself, but his study shows that i can duplicate estrogen's fat-inhibiting effectsw hen taken in daily doses equal to about 100 milligrams of isofavones. Genistein may also help block insulin's promotion of increased fat deposits in lipcytes. And Bulk Up Better Than Steroids Can!
