The kidney bean is a variety of the common bean (Phaseolus vulgaris). It is named for its visual resemblance in shape and – for the red variety – colour to a human kidney. Red kidney beans should not be confused with other red beans, such as adzuki beans.
Kidney beans are an excellent plant-based source of protein. They’re also rich in various minerals, vitamins, fibers, antioxidants, and other unique plant compounds. Therefore, these beans may aid weight loss, promote colon health, and moderate blood sugar levels.
