Yellow wax beans, like green (snap) beans, are immature bean pods eaten as a vegetable.
While it is possible to eat the young pods of nearly any common bean, special varieties have been developed that produce a succulent, fleshy young pod.
Yellow beans are a good source of lutein, beta-carotene, and vitamin A, so they are good for vision health. Lutein and beta-carotene have antioxidant effects that may help slow the effects of aging and prevent some cancers. Vitamin A may also be involved in maintaining epithelial cells�the cells that line the digestive tract and lungs. There is also a purple wax bean that may one day prove to be a good source of anthocyanins.
