Fat Facts

Fats: What are they?? Fats occur naturally in food and play an important role in nutrition. Fats and oils provide a concentrated source of energy for the body. Fats provide 9 calories per gram, more than two times the calories you get from carbohydrates and protein. Fats are used to store energy in the body, insulate body tissues, and transport fat soluble vitamins through the blood. They also play in important role in food preparation by enhancing food flavor, adding mouth-feel, making baked products tender, and conducting heat during cooking. Oils are fats that are liquid at room temperature, like the vegetable oils used in cooking. Oils come from many different plants and from fish. Some common oils are:

• canola oil
• corn oil
• cottonseed oil
• olive oil
• safflower oil
• soybean oil
• sunflower oil

Solid fats are fats that are solid at room temperature, like butter and shortening. Solid fats come from many animal foods and can be made from vegetable oils through a process called hydrogenation. Some common solid fats are:

• butter
• beef fat (tallow, suet)
• chicken fat
• pork fat (lard)
• shortening

Not All Fats and Oils Are Created Equally Fats and oils are composed of basic units called fatty acids, each type of fat or oil is a mixture of different fatty acids.

• Saturated Fatty Acids are found in animal sources such as meat and poultry, whole or reduced-fat milk, and butter. Also, some vegetable oils like coconut, palm kernel oil, and palm oil contain saturated fats. Saturated fats are usually solid at room temperature.
• Monounsaturated Fatty Acids are found mainly in vegetable oils such as canola, olive, and peanut oils. They are liquid at room temperature.
• Polyunsaturated Fatty Acids are found mainly in vegetable oils such as safflower, sunflower, corn, flaxseed, and canola oils. Polyunsaturated fats are also the main fats found in seafood. They are liquid or soft at room temperature. Specific polyunsaturated fatty acids, such as linoleic acid and alpha-linolenic acid, are called essential fatty acids. They are necessary for cell structure and making hormones. Essential fatty acids must be obtained from foods we choose.
• Trans Fatty Acids are formed when vegetable oils are processed into margarine or shortening. Sources of trans fats in the diet include snack foods and baked goods made with “partially hydrogenated oil” or “vegetable shortening.” Trans fatty acids also occur naturally in some animal products such as dairy products. *Avoid or limit products containing these oils.
