Fats

Fats also give you energy and help you feel satisfied after eating. Oils, shortening, butter, and margarine are types of fats, and mayonnaise, salad dressings, table cream, and sour cream are high in fat. Foods from animal sources and certain foods like seeds, nuts, avocado, and coconut also contain fat. There are different categories of fats—some are healthier than others:

Monounsaturated fats. These include canola oil, olive oil, peanut oil, and safflower oil. They are found in avocados, peanut butter, and some nuts and seeds.

Polyunsaturated fats. Some are corn oil, soybean oil, and flaxseed oil. They are also found in fatty fish, walnuts, and some seeds.

Saturated fats. These fats are found in red meat, milk products including butter, and palm and coconut oils. Regular cheese, pizza, and grain-based and dairy desserts are common sources of saturated fat in our meals.

Trans fats (trans fatty acids). Processed trans fats are found in stick margarine and vegetable shortening. Trans fats are often used in store-bought baked goods and fried foods at some fast-food restaurants.
olives and olive oil.

You can tell monounsaturated and polyunsaturated fats because they are liquid at room temperature. These types of fat seem to lower your chance of heart disease. But that doesn’t mean you can eat more than the Dietary Guidelines ( http://www.cnpp.usda.gov/dietaryguidelines.htm )suggest.

Trans fats and saturated fats are usually solid at room temperature. Trans fat and saturated fat can put you at greater risk for heart disease and should be limited.
