Limit organ meats such as liver, kidney, or brains. Use skim or low fat milk and cheeses, and low or nonfat yogurt. Instead of butter, use liquid or soft margarine or vegetable oils high in unsaturated fats. Use all fats and oils sparingly. Eat egg yolks only in moderation.
Egg whites contain no fat or cholesterol and can be eaten often.
Many packaged and processed foods are high in saturated fats. Get in the habit of reading food labels. Also read product labels for cholesterol content. So buy soft or liquid margarine for spreading or cooking. Also, choose those containing liquid vegetable oil as the first ingredient.
