Unsaturated fats help to lower blood cholesterol when they are substituted for saturated fat.
Just be sure to limit the total amount of any fats or oils, since even those that are unsaturated are rich sources of calories. Read the ingredient label to choose margarines containing liquid vegetable oil as the first ingredient rather than hydrogenated or partially hydrogenated oil. Use the nutrition label to choose margerines with the least amount of saturated fat. Buy margarine made with unsaturated liquid vegetable oils as the first ingredient. Choose tub or liquid margarine or vegetable oil spreads.
