Peanuts are unique whole foods that naturally contain heart-healthy monounsaturated fat, which has been linked to lowering blood cholesterol levels. Studies show adding even small amounts of peanuts to the diet have shown a 14% decrease in the "bad" cholesterol.

These legumes (related to peas and beans) are rich in Niacin (B3) which is instrumental in increasing "good" cholesterol. They are also very high in quality protein and an excellent source of Vitamin E, an important antioxidant for heart disease and cancer prevention. Peanuts are rich in good dietary fiber which promotes overall bowel health and aids in the prevention of colon cancer.
