What are trans-fatty acids? What effect do they have on cholesterol levels? In what foods are they found?
Trans-fatty acids are produced when hydrogen atoms are added to monounsaturated or polyunsaturated fats to produce a semisolid product like margarine or shortening. A product is likely to contain a significant amount of trans-fatty acids if partially hydrogenated vegetable oil is listed in the first three ingredients on the label. The major sources of trans-fatty acids in the diet are baked goods and foods eaten in restaurants. Trans-fatty acids raise low-density lipoproteins and total cholesterol.
