To avoid GM soy, look for food products that say: Contains Soy (it should be clearly listed because Soy is a common allergen); or for obvious ingredients that contain the words “soy” in the food product’s list of ingredients. Common examples of soy-based ingredients include: soy protein, soy flour, soy sauce, soybean oil, soy milk, and soy lecithin. Tofu, tempeh, and miso are other sources of soy. Steer clear of foods with all of these ingredients unless they are labeled USDA Organic or Non-GMO Project Verified.
