Saturated Fat Raise LDL and HDL levels of cholesterol Saturated fats are typically solid at room temperature. Found in animal sources, coconut and palm oil. More harmful than cholesterol. Polyunsaturated Fats Better than Saturated fats. Found in vegetable oils and fish. Lowers both the LDL and HDL cholesterol levels in blood. Monounsaturated best type of fat found in both animal and plant sources Olive, canola and peanut oils are the most common examples. Monounsaturated fats lower LDL and raise HDL levels of cholesterol in the blood Trans Fats Trans fats (or trans fatty acids) are created in an industrial process that adds hydrogen to liquid vegetable oils to make them more solid. Another name for trans fats is “partially hydrogenated oils." Look for them on the ingredient list on food packages. Worst Kind. Trans Fats cont. Trans fats raise your bad (LDL) cholesterol levels and lower your good (HDL) cholesterol levels. Increases your risk of developing heart disease and stroke.

Look for ingredients referred to as “partially hydrogenated oils.” How much TRANS fat can I eat? The American Heart Association recommends less than 1 percent of your total daily calories should be trans fats. if you need 2,000 calories a day, no more than 20 calories should come from trans fats. That’s less than 2 grams of trans fats a day. Given the amount of naturally occurring trans fats you probably eat every day, this leaves virtually no room at all for industrially manufactured trans fats. Key Recommendations for Adolescents Keep total fat intake between 25-35% of total calories. Let most of the fats you eat be polyunsaturated and monounsaturated fats such as fish, nuts and vegetable oils. Cholesterol Fat-like substance made by the body that has some useful functions: Found in every body cell Part of skin tissue Transports essential fatty acids Needed to produce hormones Types of Cholesterol The body has HDL (good) cholesterol and LDL (bad) cholesterol. “H” stands for “healthy” “L” stands for “loser”.

Tips Continued Try lemon juice on salads or use limited amounts of oil-based salad dressing. To reduce saturated fat, use margarine instead of butter in baked products and, when possible, use oil instead of shortening. Try whole-grain flours to enhance flavors of baked goods made with less fat and cholesterol-containing ingredients Replace whole milk with skim or low-fat milk in puddings, soups, and baked products. Substitute plain low-fat yogurt, blenderwhipped low-fat cottage cheese, or buttermilk in recipes that call for sour cream or mayonnaise Choose lean cuts of meat. Trim fat from meat before and/or after cooking Remove skin from poultry before cooking Cook meat or poultry on a rack so the fat will drain off. Use a nonstick pan for cooking so added fat will be unnecessary Chill meat or poultry broth until the fat becomes solid. Spoon off the fat before using the broth Limit egg yolks to one per serving when making scrambled eggs. Use additional egg whites for larger servings. Use "egg substitutes" for baking or for scrambled eggs Try substituting egg whites in recipes calling for whole eggs. For example, use two egg whites in place of each whole egg in muffins, cookies, and puddings Substitute 1/2 c. plain non-fat yogurt for the same amount of mayonnaise and save 736 calories and 89 grams of fat Fats The love/hate relationship
