This article concludes that, for optimal health, more omega-3 essential fatty acids (EFAs) should be added to the American diet.
The authors offer charts listing foods that are rich in omega-3 fatty acids, including flaxseed and fatty fish (for example: halibut, mackerel, herring, tuna, salmon, sardines). They explain that the US population gets plenty of omega-6 fatty acids in milk, vegetable oils, and meat products. The current ratio between the omega-6 and omega-3 EFAs in the US diet is about 10 to 1, but the recommended ratio is about 2.3 to 1. The authors propose that adults in the US should have at least 650 mg of the two omega-3 EFAs, DHA and EPA, each day.
