Description: Corn is rich in calcium, phosphorus, selenium, lecithin, vitamin E, with lower serum cholesterol, but also serve to prevent heart disease, coronary heart disease. Often eat corn, able to absorb excess body fat, both nutrition and health, not weight loss when one of the best dietary choices. It is said that the Indians almost no risk of hypertension and coronary heart because they long to eat corn.
