Key Facts to Know

  • Phytoestrogens isoflavones in soy and other plants possess antioxidant and antimicrobial properties. They are the source of much past confusion over soy safety; however, research confirms their safety in humans. Phytoestrogens are structurally similar to estrogens, but act differently and are much weaker.(i,ii)
  • Soy is beneficial for athletic performance and muscle recovery, and is rich in antioxidant compounds that may help reduce oxidative stress associated with exercise. Soy protein provides an intermediate rate of amino acid release, and when combined with other proteins, such as whey and casein, offers a sustained delivery of amino acids to muscles.(iii) Learn more in this SCANNERS article, The Role of Soy in the Performance of Active and Athletic Americans.
  • Studies show moderate intake of two to three servings of soyfoods a day are safe. A serving is: 1 cup soymilk or cultured soymilk yogurt; 1/2 cup cooked soybeans, edamame, tempeh or tofu; 1/3 cup soynuts; a soy-rich nutrition bar; or a veggie burger.(iv)
