Kidney beans, or Phaseolus vulgaris, are a type of legume that originated in Central America and Mexico. The common bean is a significant food crop and a significant source of protein worldwide. Kidney beans are frequently consumed well cooked and are used in a variety of traditional dishes. Kidney beans that are consumed raw or cooked incorrectly are poisonous, but beans that are properly prepared can be a beneficial part of a balanced diet. In addition to white, cream, black, red, purple, and other hues and patterns, they can also be spotted, striped, or mottled.
