Phaseolus vulgaris, also known as the common bean and French bean, is a herbaceous annual plant grown worldwide for its edible dry seeds or unripe fruit (both commonly called beans). Beans are among the most versatile and commonly eaten foods throughout the world. Because of their nutritional composition, these economical foods have the potential to improve the diet quality and long-term health of those who consume beans regularly. Beans contain a variety of vitamins, minerals and other nutrients while providing a moderate amount of calories. Beans provide protein, fiber, folate, iron, potassium and magnesium while containing little or no total fat, trans-fat, sodium and cholesterol. Because of their high concentration of health-promoting nutrients, consuming more beans in the diet could improve overall health and also decrease the risk of developing certain diseases.
