Corn oil is an effective component in lowering blood cholesterol levels. Corn oil offers high levels of polyunsaturated instead of saturated fats. Polyunsaturated fats lower blood cholesterol levels. Monounsaturated fats neither lower nor raise blood cholesterol levels. Saturated fats are approximately twice as powerful in raising cholesterol levels as polyunsaturated fats are in lowering them. Corn oil contains about 60 percent polyunsaturated, 25 to 30 percent monounsaturated and 10 to 15 percent saturated fats. In fact, the Food and Drug Administration has acknowledged the unsaturated fat benefits of corn oil in reducing the risk of heart disease. See the FDA's letter to ACH Food Companies, Inc. regarding qualified health claims. Research has shown that phytosterols play an important role in reducing blood cholesterol by inhibiting its absorption from the intestines. According to the U.S. Department of Agriculture, corn oil contains 968 milligrams of phytosterols per 100 grams of oil. It has one of the highest phytosterol levels of the refined vegetable oils. Only rice-bran oil has a higher phytosterol content at 1, 190 mg100 grams. Corn oil is the only product that contains a natural mixture of free phytosterol, phytosterol esters and phytostanol esters.Blood Pressure Numerous human studies show that diets enriched in polyunsaturated fatty acids can significantly lower elevated blood pressure in individuals with high blood pressure. Corn oil was used in many of these studies. Corn oil diets have shown blood pressure lowering of about 12 percent in men and 5 percent in women who had elevated blood pressure (mild hypertension). No significant effect of polyunsaturates has been noted in persons with normal blood pressure.Essential Fatty Acids
