Omega-6 fatty acids
They are an essential fatty acid that the body needs for normal growth and development. The body needs a healthy balance of omega-6 and omega-3 fatty acids. Excess consumption of omega-6s can trigger the body to produce pro-inflammatory chemicals. These fatty acids are found in oils such corn, safflower, sunflower, grapeseed, soy, peanut, and vegetable; mayonnaise; and many salad dressings.
