Soy-based products are made from soybeans, a type of legume that is rich in protein and other nutrients. Common soy-based foods include tofu, soy milk, and edamame. These products are popular among vegetarians and vegans as they provide a plant-based source of protein and can be used in various dishes. In addition to food, soybeans are also used to create soy sauce, a common condiment in Asian cuisine, and tempeh, a fermented soy product. Soy-based ingredients are often found in processed foods, providing texture and flavor while also contributing to a balanced diet.
