The kidney bean is a type of legume that gets its name from its shape, which resembles a human kidney. These beans are commonly found in various dishes, especially in chili and salads. They are rich in protein, fiber, and essential nutrients, making them a healthy addition to many meals. Kidney beans come in different colors, including red and white, and are often used in vegetarian and vegan recipes. When cooked properly, they have a firm texture and a slightly sweet flavor. However, it's important to cook them thoroughly, as raw or undercooked kidney beans can be toxic due to a natural toxin called phytohaemagglutinin.
