Apples have many nutrition benefits. They are low in calories, have no fat, and are high in both soluble and insoluble fiber. A study published in the September 2002 issue of the American Journal of Clinical Nutrition reports that the flavonoids (plant pigments with antioxidant activity) found in apples may reduce the risk of many chronic diseases such as heart disease, cancer, stroke, type-2 diabetes, and asthma. Quercetin, an antioxidant flavonoid found in high concentrations in apples, is thought to be responsible for apples’ potential benefit in preventing lung cancer.
