are not sure about what different fats are and how they affect your body. Here are a few facts from the National Centre for Nutrition and Dietetics to help you out: Saturated fats - are usually solid at room temperature and primarily come from animal foods such as meat, poultry, butter and whole milk. Coconut, palm and palm kernel oils are also high in saturated fat. Saturated fat is responsible for raising cholesterol levels.

Polyunsaturated fats -- usually are liquid at room temperature and are found in vegetable oils. Safflower, sunflower, corn, and soybean oils contain the highest amounts of polyunsaturated fats, such as corn oil, can help decrease high blood cholesterol levels when part of a healthful diet.

Monounsaturated fats -- also are liquid at room temperature and are found in vegetable oils, such as canola and olive. Monosaturated fats can help decrease high blood cholesterol levels if part of a lower-fat diet.

Dietary cholesterol -- comes only from animal sources such as the fat in dairy products, egg yolks, meats, poultry, and seafood. Vegetables, fruits and grains do not contain cholesterol.
