Not all fat is bad for you. In fact, fat is an important part of a
healthy diet. Fat comes from both animal and vegetable sources. Animal sources include meat, poultry, fish, and butter. Plant sources include nuts, avocados, and
vegetable oils.
Even though fats are high in calories, they are important because they:
• Make you feel full and satisfied
• Store energy in the body
• Help your body use vitamins A, D, E, and K
• Form a part of the membrane of every cell
• Provide a source of energy during starvation
Some fats even protect the body against heart disease and other health conditions.
Not all fats are good for you, though. These fats are not healthy for your body:
• Saturated fats
• Trans fatty acids
Saturated fats come mainly from animal sources (like meat or butter). Trans fatty acids are found mostly in processed foods (like packaged cookies). They are almost never found in whole foods. For good health, eat more unsaturated fats. These fats come mainly from plant sources (like olives).
How much fat do you need each day?
Most adults should limit how much fat they eat to:
• About 20–35 percent of their calories
Limit saturated fats to:
• No more than 10 percent of your total calories
