Although omega-3 fatty acids have been known as essential to normal growth and health since the 1930s, awareness of their health benefits has dramatically increased since the 1980s.[98][99]
On September 8, 2004, the U.S. Food and Drug Administration gave "qualified health claim" status to EPA and DHA omega-3 fatty acids, stating, "supportive but not conclusive research shows that consumption of EPA and DHA [omega-3] fatty acids may reduce the risk of coronary heart disease".[100] This updated and modified their health risk advice letter of 2001 (see below). As of this writing,[when?] regulatory agencies[who?] do not accept that there is sufficient evidence for any of the suggested benefits of DHA and EPA other than for cardiovascular health.
The Canadian Food Inspection Agency has recognized the importance of DHA omega-3 and permits the following claim for DHA: "DHA, an omega-3 fatty acid, supports the normal physical development of the brain, eyes and nerves primarily in children under two year of age."[101]
