• Eat a dietary pattern that emphasizes fruits, vegetables, whole grains, low-fat dairy products, poultry, fish and nuts. Also limit red meat and sugary foods and beverages. 
• Use naturally occurring, unhydrogenated vegetable oils such as canola, safflower, sunflower or olive oil most often. 
• Read nutrition labels and look for processed foods made with unhydrogenated oil rather than partially hydrogenated or hydrogenated vegetable oils or saturated fat. 
• Use soft margarine as a substitute for butter, and choose soft margarines (liquid or tub varieties) over harder stick forms. Look for "0 g trans fat" on the Nutrition Facts label and no hydrogenated oils in the ingredients list. 
• Doughnuts, cookies, crackers, muffins, pies and cakes are examples of foods that may contain trans fat. Limit how frequently you eat them.
