Omega-3 fatty acids: The science and the beliefs

The importance of Omega-3 fatty acids intake from dietary supplements or from food sources (mainly fish) has recently become a common knowledge in the mass media as well as in popular science magazines and advertisements. We therefore wish to review the updated evidence- based literature regarding the relationship between Omega-3 fatty acid intake and morbidity and in its preventative effects in cardiovascular, bone, kidney, autoimmune, GI tract diseases, CNS and mental diseases, cancer, diabetes, asthma, opthamological health, organ transplants and child and maternal health. Recommendations regarding optimal intake of these fatty acids throughout the lifecycle of various health authorities will be cited. We shall conclude with the authors' recommendations for optimal Omega-3 intake in Israel: Recommendations for the general population is to consume at least two weekly portions of fatty fish. For patients with hypertrigliceridemia dietary supplements containing fish oil in addition to the above diet can be considered as a part of the whole medical treatment and follow up. Limiting fish consumption in risk group populations such as pregnant women will also be considered.
