==Food Sources==
Genistein is found in plant foods such as soybeans, chickpeas, broccoli, cauliflower, alfalfa sprouts, clover sprouts, barley meal, sunflower seeds, and clover seeds. It is also found in many soy-based products such as soy milk, tempeh, miso, soy flour, infant formula, sports drinks, protein bars, and textured soy protein. Textured soy protein (TSP) is used as a meat substitute in vegetarian hamburgers, hot dogs, sausages, and meatballs. Though soy is by far the most common dietary source of genistein, it is not found in soy sauce or soybean oil. Genistein is also available as a dietary supplement in powder, pill, or capsule form.
