Most animal and vegetable fats contain monounsaturated fats, but in varying quantities. They are usually in liquid form at room temperature, but they may begin to solidify if it is chilled. Monounsaturated fats are the most desirable type of fat in the diet because they help to decrease the LDL (bad) cholesterol in the blood and help to increase the HDL (good) cholesterol. Good sources of monounsaturated fat are olive oil, canola oil, peanut oil, and most nuts. Olive oil has the highest percentage (about 77%) of monounsaturated fats of any edible oil.
