Phaseolus vulgaris, commonly known as the common bean, kidney bean or French bean, is a species of legume. It is an important source of protein, fiber, and various other nutrients. The term "common bean" or "kidney bean" is commonly used interchangeably with Phaseolus vulgaris. Other synonyms for this species include haricot bean, navy bean, pinto bean, and snap bean. The haricot bean is typically smaller and more delicately flavored than other beans, while the navy bean is small and oval with a white color. Pinto beans are speckled and are a staple in Mexican cuisine, while snap beans are a type of green bean that is harvested while still young and tender.
