Most omega-6 fatty acids are consumed in the diet from vegetable oils, such as linoleic acid. Excessive amounts of linoleic acid can contribute to inflammation and result in heart disease, cancer, asthma, arthritis and depression. 3,4.hey are considered essential fatty acids because the body cannot manufacture them. Omega-9 fatty acids are from a family of monounsaturated fats that also are beneficial when obtained in food. Omega-9 Canola and Sunflower Oils are uniquely high in omega-9 (monounsaturated) fatty acid.
The types of unsaturated fats are: the monounsaturated and polyunsaturated fats, which are found in nuts, fish, and vegetable and fruit oils.These fats are naturally unsaturated because they do not contain the maximum number of hydrogen atoms, and usually remain liquid at room temperature.here are two main types of unsaturated fat: monounsaturated and polyunsaturated. Monounsaturated fats occur mostly in plant oils. Good sources of monounsaturated fats include: Polyunsaturated fats are found in plant foods and some fish.
