Omega-3 fatty acids are a type of polyunsaturated fat (like omega-6), considered an essential fatty acid because it cannot be manufactured by the body. As a result, people must obtain omega-3 fatty acids from foods such as fish, nut, and plant-based oils such as canola oil and sunflower oils.hat are they? Omega-6 fatty acid is also a polyunsaturated fat, essential for human health because it cannot be made in the body. For this reason, people must obtain omega-6 fatty acids by consuming foods such as meat, poultry, and eggs as well as nut and plant-based oils such as canola and sunflower oils.
For example, around 75 percent of the fatty acids in olive oil are monounsaturatedâso scientists classify it as a monounsaturated fat. Safflower oil, on the other hand, contains around 75 percent of its fatty acids in the form of polyunsaturated fat, so it's known as a polyunsaturated fat.he major difference between these fatty acids lies in the type of molecules they're made up of, and the degree to which these molecules are saturated with hydrogen atoms. Every type of fat, whether it's from a vegetable source or an animal source, actually contains a mixture of all three of these fatty acids.
