The omega-6 linoleic acid and the omega-3 alpha-linolenic acid are two essential nutrients. As essential nutrients, they cannot be synthesised by the body, but must be ingested directly in the form of food or dietary supplements.
These fatty acids are necessary for different main functions in the body. However, in Western society, the ratio of intake of omega-6 fatty acids, to the intake of omega-3 fatty acids is too high and can lead to the formation of excess arachidonic acid and potentially bring the formation of unfavourable eicosanoid products in the body. Science now supports the importance of reducing the intake of omega-6 fatty acids, such as linoleic acid and increasing the intake of omega-3 fatty acids in the diet.
