A legume is a type of plant that belongs to the family Fabaceae. These plants produce seeds in pods, which can be eaten or used in various dishes. Common examples of legumes include beans, lentils, and peas. They are known for being rich in protein, fiber, and essential nutrients, making them a popular choice for both vegetarians and meat-eaters alike. Legumes also play an important role in agriculture. They have the unique ability to fix nitrogen in the soil, which helps improve soil fertility. This makes them valuable in crop rotation systems, as they can enhance the growth of other plants, such as corn and wheat.
