Omega-3 and Omega-6 Fatty Acids in Serum Lipids and Their Relationship to Human Disease
It is now nearly 80 years since omega-6 acids were found to be an essential nutrient in rats1. It was later shown that they were essential also in man, and that omega-3 fatty acids were essential nutrients in several animal species2,3. Although omega-3 fatty acids have been suggested to protect against cardiovascular disease, rheumatoid arthritis and some types of cancer4, they have not until recently been considered essential in man. The FAO/WHO recommendations on essential fatty acid requirement in man accordingly do not mention α-linolenic or other omega-3 fatty acids as essential nutrients, and only state the requirement for linoleic and other omega-6 fatty acids5.
