Bean sprouts are a crunchy, satisfying ingredient used in everything from salads to noodle soups. They are low in calories and have a light, fresh flavor while also a storehouse of nutrition. Bean sprouts consist of vitamins B, C, B1, B6, K and A. They are also a source of iron, magnesium, phosphorus, calcium, potassium, and manganese, as well as omega 3 fatty acids. Although many different varieties of beans can be used to grow bean sprouts, we use the most commonly consumed variety, mung bean.
