What do fats do in my diet?
Fats actually have a job to do. You cannot live without them. In our bodies, fats do the following:
- Some vitamins only work in the body when taken with fat (like vitamins A, D, E and K).
- Fat is important for proper growth and proper functioning and health of our skin, brain and nervous system.
- Fat adds flavor to food.
- Fat can help you feel full after a meal or snack.
What are the different types of fats?
There are many types of fats. Some are healthy and some are unhealthy.
Healthy fats are called unsaturated fats. Unsaturated fats are better choices than saturated fats. Unsaturated fats are liquid at room temperature. They come mostly from plants.
There are two types of unsaturated fats, which include:
- Monounsaturated fats. Examples include olive oil, canola oil avocado and nuts.
- Polyunsaturated fats. Examples include oils from safflower, sunflower, corn, soybeans, fatty fish (like salmon or tuna), walnuts, and flaxseed.
Unhealthy fats are solid at room temperature. Examples include butter, coconut oil and shortening. The types of unhealthy fats include:
- Saturated fats (unhealthy fats). Saturated fats raise blood cholesterol (fat levels in the blood). Saturated fats are solid at room temperature. They are found mostly in animal foods, such as butter, meat or cheese. Some vegetable oils also have saturated fat. This includes coconut, palm and palm kernel oil.
- Trans fats. These are made when unsaturated fats become solid. Examples include margarine, vegetable shortening and processed foods with partially hydrogenated vegetable oil. Trans fats raise blood cholesterol levels should be avoided.
Did you know…?
The most important way to lower blood cholesterol is actually eating less saturated fat, not cholesterol, in your diet.
Tips to change the fats in your diet
- Choose lean chicken or fish more than red meats.
- Pick leaner cuts of red meats.
- Trim all the fat you see from food.
- Limit high cholesterol foods like egg yolks and whole dairy products.
- Limit foods labeled creamy, battered or fried.
- When eating out, ask for no butter or gravy on the side.
- Limit high-fat sweets, such as ice cream or baked goods. Instead, choose fresh fruit, Jell-O®, sherbet, low-fat yogurt or angel food cake.
- Take the skin off the chicken or turkey before you cook. Most of the fat is in the skin or between the skin and meat.
- Bake, broil, steam or microwave foods.
- If you use fat to cook, pick the healthier monounsaturated fats like olive or canola oil.
- Add flavor with herbs, spices, lemon or lime juice, salsa, mustard, garlic, seasoned vinegar or onion.
