Look for processed foods made with unhydrogenated oil rather than partially hydrogenated or hydrogenated vegetable oils or saturated fat. Doughnuts, cookies, crackers, muffins and cakes are examples of foods that may contain trans fat. Limit how frequently you eat them. Avoid using vanaspati ghee while cooking at home.
