  2. Beans are commonly used in chili and refried beans, while legumes like lentils and chickpeas are used in soups and curries.
  3. Beans and legumes are nutrient-dense foods high in protein, fiber, and various vitamins and minerals.

Beans vs Legumes

Beans are a specific type of legume that are grown for their edible seeds. Legumes are a family of plants that include beans, peas, lentils, chickpeas, and peanuts, among others, and are characterized by their ability to fix nitrogen in the soil, which means they can contribute to soil fertility.

Beans vs Legumes

Legumes refer to the plants of the Fabaceae family, which will bear a pod that splits into both sides and contains between one and twelve fruits or seeds.

Beans, however, are one type of seed of these plants belonging to a specific Fabaceae family genus known as phaseolus.
