Fats also help the body absorb necessary fat-soluble vitamins vitamins A, D, E and K , said Jim White , a Virginia Beach-based registered dietitian, health fitness specialist and a spokesperson for the Academy of Nutrition and Dietetics. Dietary fat also helps keep hair and skin healthy, insulates the body, protects organs and fills fat cells.
There are several types of fat — some good, some bad, some well understood and some less so. Saturated fats and trans fats are commonly considered unhealthy, while unsaturated fats — including monounsaturated and polyunsaturated fat — are considered healthy. All foods that contain fats have a mix of fat types, according to the Harvard School of Public Health.
Saturated fats are saturated with hydrogen molecules. According to White, saturated fat comes from animal sources, such as red meats, poultry and full-or-reduced fat dairy products. She cited lard as an example. Other examples include cheese and butter.
Oils that are solid at room temperature, like palm oil, palm kernel oil and coconut oil, also contain saturated fats. This means that baked goods can be high in saturated fats. Saturated fats also tend to contain a lot of calories. This puts someone on a 2,calorie-a-day diet with calories or 13 grams of saturated fats per day.
The U. Dietary Guidelines allow for up to 10 percent of calories to come from saturated fat.
According to Jimenez, trans fats are sometimes found naturally in meats or dairy, but usually in small amounts. These are called partially hydrogenated oils. Other common sources of trans fats include baked goods, crackers, refrigerated dough, margarine and coffee creamer.
Fast food restaurants often use them in deep fryers because partially hydrogenated oil does not have to be changed as often as regular oil. In fact, they are often considered the worst type of fat. According to the AHA, they both lower your good cholesterol and increase your bad cholesterol. In , the FDA decreed that partially hydrogenated oils were no longer considered safe. There is currently a three-year adjustment period in place so that food manufacturers can change their practices or seek approval.
Triglycerides are a potentially dangerous type of fat found in blood, according to the NIH.
They are associated with coronary artery disease, especially in women. The body converts any calories it doesn't need to use right away into triglycerides, which are stored in the fat cells.

They are supposed to provide energy between meals, according to the Mayo Clinic. If you eat more calories than you expend, however, the body does not burn triglycerides, and they accumulate. Most types of fat we eat become triglycerides. These fats get their name because they are not saturated with hydrogen molecules and because they have a single carbon bond in the fat molecule called a double bond. Olives and avocadoes also contain monounsaturated fats, White added. White noted that they have been linked to improved cholesterol levels, and the Mayo Clinic adds that they may help insulin levels and blood sugar control.
It is still important to watch your intake of monounsaturated fats because of their high caloric content, said Jimenez. Though there are no specific guidelines on how many monounsaturated fats to consume, the Mayo Clinic suggests that most of your total fat intake should come from healthy fats. Like monounsaturated fats, polyunsaturated fats are not saturated with hydrogen molecules.
They get their name from having more than one carbon bond double bond in the fat molecule, according to the AHA. They are liquid at room temperature. Polyunsaturated fats are found mostly in plant food sources, such as soybeans and soybean oil, sunflower oil, sunflower seeds, walnuts and flaxseeds, White said. They also help with cell development and maintenance and add vitamin E to your diet.
Polyunsatured fats provide essential fatty acids, including omega-6 and omega-3, according to White. Though there are no specific guidelines on how many polyunsaturated fats to consume, the Mayo Clinic suggests that most of your total fat intake should come from healthy fats.
