What Are The Different Types Of Fats? 1. Unhealthy fats Saturated fat : Saturated fats are mostly in animal foods, such as meat and dairy foods. Tropical oils, such as coconut oil, palm oil, and cocoa butter, are also saturated fats. Trans fat : Trans fats include shortening, partially hydrogenated vegetable oils, and hydrogenated vegetable oils. Trans fats are made when a liquid fat is turned into a solid fat (for example, when corn oil is made into stick margarine). They are in many processed foods, such as cookies, crackers, and snack foods. 2. Healthy fats Monounsaturated fat. Monounsaturated fats are liquid at room temperature but get solid when refrigerated. Eating foods that are high in this fat may help lower your "bad" (LDL) cholesterol, keep your "good" (HDL) cholesterol level up, and lower your chances of getting coronary artery disease. This fat is found in canola oil, olive oil, peanut oil, olives, avocados, nuts, and nut butters.
