Fats belong to a group of substances called lipids. Fats come in liquid or solid form. All fats are combinations of saturated and unsaturated fatty acids. Fats can be called very saturated or very unsaturated depending on their proportions. Animal sources include meat, poultry, and whole-milk dairy products such as cheese, milk, ice cream, cream, butter, and lard.
Unsaturated fat is a type of fat that is usually liquid at refrigerator temperature.
Monounsaturated and polyunsaturated fat are two kinds of unsaturated fat. It is a slightly unsaturated fat. Polyunsaturated fat is highly unsaturated fat that is found in large amounts in foods from plants, including safflower, sunflower, corn, and soybean oil. Seafood is lower in saturated fat than meat. Fat provides 9 Calories per gram, more than twice the number provided by carbohydrates or protein.
