What is low-fat eating?

Most food has some fat in it. Your body needs some fat to be healthy. But some kinds of fats are healthier than others.

In a low-fat eating plan, you try to choose healthier fats and eat fewer unhealthy fats. Healthy fats include olive and canola oil. Try to avoid eating too much saturated fat, such as in cheese and meats.

You do not need to cut all fat from your diet. But you can make healthier choices about the types and amount of fat you eat.

Even though it is a good idea to choose healthier fats, it is still important to be careful of how much fat you eat, because all fats are high in calories.

What are the different types of fats?

Unhealthy fats

• Saturated fat. Saturated fats are mostly in animal foods, such as meat and dairy foods. Tropical oils, such as coconut oil, palm oil, and cocoa butter, are also saturated fats.
• Trans fat. Trans fats include shortening, partially hydrogenated vegetable oils, and hydrogenated vegetable oils. Trans fats are made when a liquid fat is turned into a solid fat (for example, when corn oil is made into hard margarine). They are in many processed foods, such as cookies, crackers, and snack foods.
• Cholesterol. Cholesterol is only in animal products, such as eggs, dairy foods, and meats.

Healthy fats

• Monounsaturated fat. Monounsaturated fats are liquid at room temperature but get solid when refrigerated. Eating foods that are high in this fat may help lower your "bad" (LDL) cholesterol, raise your "good" (HDL) cholesterol, and lower your chances of getting coronary artery disease. This fat is found in canola oil, olive oil, peanut oil, olives, avocados, nuts, and nut butters.
• Polyunsaturated fat. Polyunsaturated fats are liquid at room temperature. They are in safflower, sunflower, corn oils, flaxseed oil, ground flaxseed, soybeans, walnuts and seeds. They are also the main fat in seafood. Omega-3 fatty acids are types of polyunsaturated fat. Eating fish may lower your chances of getting coronary artery disease. Fatty fish such as salmon and mackerel contain these healthy fatty acids.

Why cut down on unhealthy fats?

Eating foods that contain saturated fats can raise the LDL ("bad") cholesterol in your blood. Having a high level of LDL cholesterol increases your chance of hardening of the arteries (atherosclerosis), which can lead to heart disease, heart attack, and stroke.

If you're not sure how much fat you should be eating or how many calories you need each day to stay at a healthy weight, talk to a registered dietitian. A dietitian can help you create a plan that's right for you.

What can you do to cut down on fat?

Foods like cheese, butter, sausage, and desserts can have a lot of unhealthy fats. Try these tips for healthier meals at home and when you eat out.

At home

• Fill up on fruits, vegetables, and whole grains.
• Think of meat as a side dish instead of as the main part of your meal.
• When you do eat meat, make it extra-lean ground beef (97% lean), ground turkey breast (without skin added), meats with fat trimmed off before cooking, or skinless chicken.
• Try main dishes that use whole wheat pasta, brown rice, dried beans, or vegetables.
• Use cooking methods that use little or no fat, such as broiling, steaming, or grilling. Use cooking spray instead of oil. If you use oil, use a monounsaturated oil, such as canola or olive oil.
• Read food labels on canned, bottled, or packaged foods. Choose those with little saturated fat.

When eating out at a restaurant

• Order foods that are broiled or poached instead of fried or breaded.
• Cut back on the amount of butter or margarine that you use on bread. Use small amounts of olive oil instead.
• Order sauces, gravies, and salad dressings on the side, and use only a little.
• When you order pasta, choose tomato sauce instead of cream sauce.
• Ask for salsa with your baked potato instead of sour cream, butter, cheese, or bacon.
