I'm interested in its value as a protein supplement for weight lifting.
Soy milk is a fine choice for weight lifting.
In fact, it's a fine choice to add to your diet , period. More and more, researchers have been documenting the benefits of soy. People who ate 47 grams of soy protein a day enjoyed a 13 percent drop in LDL cholesterol, without reducing levels of the beneficial HDL cholesterol. Soy contains compounds called isoflavones and lignans, which are converted by bacteria in the intestines into phytoestrogens. These may protect against prostate cancer in men, and breast cancer, fibroids, and other estrogen-driven diseases in women.
