Soy Protein 1 article

Made from soybeans, soy protein appears in beverages, powders, bars, meat alternatives and many other formulated foods. Common commercial forms include soy protein isolate and concentrate, which differ in protein concentration and remaining carbohydrate or fiber. Soy is a complete protein source but also a major food allergen in U.S. labeling. That combination makes both protein form and allergen declaration important when comparing products that use soy-based protein.
