List three contributions of fat to the body

Fat provide nutrients and maintains your core body temperature. You need to consume fat every day to support these functions, but some types of fat are better for you than others. Good fats protect your heart and keep your body healthy, while bad fats increase your risk of disease and damage your heart.

A Source of Energy

While carbohydrates are the main source of fuel in your body, your system turns to fat as a backup energy source when carbohydrates are not available.

Vitamin Absorption

Some types of vitamins rely on fat for absorption and storage. Vitamins A, D, E and K, called fat-soluble vitamins, cannot function without adequate daily fat intake. These vitamins are essential parts of your daily diet.

Insulation and Temperature Regulation

Fat cells, stored in adipose tissue, insulate your body and help sustain a normal core body temperature.

Choosing Good vs. Bad Fats

Opt for good monounsaturated and polyunsaturated fats, or MUFAs and PUFAs, whenever possible. These heart-healthy fats stabilize cholesterol levels and lower your overall risk of cardiovascular disease when you consume them in place of bad fats. Monounsaturated and polyunsaturated fats come from vegetable oils, nuts, avocados and cold-water fish, such as salmon and tuna. Bad fats, or saturated and trans fats, raise low-density lipoprotein, also called LDL, cholesterol. Elevated low-density lipoprotein hardens arteries and raises blood pressure. Over time, you may be more at risk of heart attack and stroke. You need increased levels of high-density lipoprotein to rid your body of excess low-density lipoprotein. Trans fats are especially harmful because they lower your high-density lipoprotein, also called HDL cholesterol, reports "The New York Times." Saturated and trans fats are naturally occurring in meat, seafood and dairy, but processed junk foods also contain these damaging fats.
