Description

Yard-long beans are one of the ancient cultivated crops. Young, immature pods are one of the very low-calorie vegetables; 100 g beans contain just 47 calories.

The pods contain large quantities of soluble and insoluble fibers. Since the entire green pod is eaten as in green beans, sufficient amount of dietary fiber is obtained in the diet. Dietary fiber helps to protect the colon mucosa by reducing its exposure time to toxic substances as well as by binding to cancer-causing chemicals in the colon. Fiber rich food also found to reduce LDL-cholesterol levels by decreasing reabsorption of cholesterol binding bile acids in the colon.
