Wing beans are an excellent source of copper, iron, manganese, tryptophan, and the essential amino acid isoleucine. They are also rich in protein, fiber, complex carbohydrates, all of the essential B-complex vitamins, calcium, phosphorus, magnesium, zinc, and potassium. The pods, leaves and roots all contain a similar nutrient makeup. Wing beans are most often cooked. Young pods can be eaten raw in salads, sliced very thinly, or lightly blanched. They are prepared like French beans or snap peas by pinching off the ends and cutting into bite-sized sections. Use in stir-fry, sautés or add to soups and stews towards the end of the cooking process.
