Polyunsaturated Fat is an unsaturated fat that usually comes from vegetables, seeds, or nuts such as corn, safflower, sunflower, soybean, cottonseed, and sesame seeds. These fats are liquid at room temperature. Mayo Clinic believes that Polyunsaturated Fats are (along with Monounsaturated Fats) your best options when choosing a fat. Polyunsaturated fats, “if used in place of other fats, can lower your risk of heart disease by reducing the total cholesterol and low-density lipoprotein (LDL) cholesterol levels in your blood.”Two types of polyunsaturated fats, Omega-3 Fatty Acids and Omega 6 Fatty Acids are so important to our health that they are called “Essential Fatty Acids.” Omega-3 Fatty Acids appear to decrease the risk of coronary artery disease. They may also protect against irregular heartbeats and help lower blood pressure levels. Omega-6 Fatty Acids help maintain bone health and regulate the metabolism.
