Monounsaturated fatty acids (MUFAs) have one double bond. Plant sources that are rich in MUFAs include vegetable oils (e.g., canola oil, olive oil, high oleic safflower and sunflower oils) that are liquid at room temperature and nuts.
A type of unsaturated fatty acid in which the chain of carbon atoms is missing one pair of hydrogen atoms. Monounsaturated fat is found mostly in vegetable oils such as soybean, olive, canola, and peanut. Because it aids stability, oils high in monounsaturated fatty acids are good for frying applications Soybean oil contains approximately 24 percent monounsaturated fatty acids. When substituted for saturated fat, mono-unsaturated fat helps lower LDL cholesterol levels while leaving HDL cholesterol levels unchanged.
