Information on Dietary Fats
Dietary Fats - know which types to choose
When choosing fats, pick unsaturated fat over saturated or trans fat. Here's how to know the difference.
Most foods contain several different kinds of fats — including saturated, polyunsaturated, monounsaturated and trans fats — and some kinds are better for your health than others are.
You don't need to completely eliminate all fats from your meals. Instead, choose the healthier types of fats and enjoy them in moderation.
Heathy Fats
When choosing fats, your best options are unsaturated fats: monounsaturated and polyunsaturated fats. These fats, if used in place of others, can lower your risk of heart disease by reducing the total cholesterol and low-density lipoprotein (LDL) cholesterol levels in your blood.
One type of polyunsaturated fat, omega-3 fatty acids, may be especially beneficial to your heart. Omega-3s appear to decrease the risk of coronary artery disease. They may also protect against irregular heartbeats and help lower blood pressure levels.
Type of healthy fat and best food sources
Monounsaturated fat
Food source: Olive oil, peanut oil, canola oil, avocados, nuts and seeds
Polyunsaturated fat
Food source: Vegetable oils (such as safflower, corn, sunflower, soy and cottonseed oils), nuts and seeds
Omega-3 fatty acids
Food source: Fatty, cold-water fish (such as salmon, mackerel and herring), flaxseeds, flax oil and walnuts
Harmful Fats
Saturated and trans fats (trans-fatty acids) are less healthy kinds of fats. They can increase your risk of heart disease by increasing your total and LDL ("bad") cholesterol. Dietary cholesterol isn't technically a fat, but it's found in food derived from animal sources. Intake of dietary cholesterol increases blood cholesterol levels, but not as much as saturated and trans fats do, and not to the same degree in all people.
Type of harmful fat and their common food sources
Saturated fat
Food source: Animal products (such as meat, poultry, seafood, eggs, dairy products, lard and butter), and coconut, palm and other tropical oils
Trans fat
Food source: Partially hydrogenated vegetable oils, commercial baked goods (such as crackers, cookies and cakes), fried foods (such as doughnuts )
Daily Limits for Fat Intake
The U.S. Department of Agriculture (USDA) and the Department of Health and Human Services (HHS) recommend that fat make up no more than 35 percent of your daily calories. This means that if you consume 1,800 calories a day, eat no more than 70 grams of fat daily. (To figure: Multiply 1,800 by 0.35 to get 630 calories, and divide that number by 9, the number of calories per gram of fat, to get 70 grams of total fat.) Keep in mind, however, that this is an upper limit and that most of these fat calories should come from monounsaturated and polyunsaturated sources.
In addition, the USDA and HHS recommend these upper limits for saturated fat and dietary cholesterol for healthy adults:
Saturated fat
Recommendation: Less than 10 percent of your total daily calories
Dietary cholesterol
Recommendation: Less than 300 milligrams a day
Though the USDA and HHS haven't yet established an upper limit for trans fat, they do suggest that you keep your trans fat intake as low as possible. The American Heart Association, on the other hand, has set an upper limit for trans fat — no more than 1 percent of your total daily calories. For most people, this is less than 2 grams a day.
Be aware that many foods contain different kinds of fat and varying levels of each type. For example, butter contains unsaturated fats, but a large percentage of the total fat is saturated fat. And canola oil has a high percentage of monounsaturated fat, but also contains smaller amounts of polyunsaturated fat and saturated fat.
Tips For Choosing The Best Types of Fat
Limit fat in your diet, but don't try to cut it out completely. Focus on reducing foods high in saturated fat, trans fat and cholesterol, and select more foods made with unsaturated fats. Consider these tips when making your choices:
· Saute with olive oil instead of butter.
· Use olive oil in salad dressings and marinades. Use canola oil when baking.
· Sprinkle slivered nuts or sunflower seeds on salads instead of bacon bits.
· Snack on a small handful of nuts rather than potato chips or processed crackers. Or try peanut butter or other nut-butter spreads — nonhydrogenated — on celery, bananas, or rice or popcorn cakes.
· Add slices of avocado, rather than cheese, to your sandwich.
· Prepare fish such as salmon and mackerel, which contain monounsaturated and omega-3 fats, instead of meat one or two times a week.
Monounsaturated and polyunsaturated fats have few adverse effects on blood cholesterol levels, but you still need to consume all fats in moderation. Eating large amounts of any fat adds excess calories. Also make sure that fatty foods don't replace more nutritious options, such as fruits, vegetables, legumes or whole grains.
