Importance of Fat
Fat is essential for several bodily functions. It is an energy source, and it protects the skeleton and nerves. Fat also makes it possible for other nutrients to do their jobs. However, not all dietary fats are equally beneficial: Saturated and trans fats can raise cholesterol levels and increase disease risk. Unsaturated fats support health and may be monounsaturated or polyunsaturated. Meats, dairy products, snack foods, and baked goods contain saturated and trans fats. Some sources of unsaturated — healthful — fats include nuts, oils, seeds, and avocados. Fats are classified in a range of ways, depending on their attributes: Fats or fatty acids : These terms can refer to any type of fat, but “fats” usually describes those that are solid at room temperature. Lipids : This can refer to any type, regardless of whether it is liquid or solid. Oils : This can describe any fat that is liquid at room temperature. Animal fats : Among these are butter, cream, and fats in meats, such as lard
