Omega 3 Research
There is no shortage of omega 3 research. Because this website is on macular degeneration I will limit the research to studies dealing with macular degeneration and omega 3s.
Increased Omega 3 Intake Reduces AMD Risk
Researchers at the Massachusetts Eye and Ear Infirmary and Department of Biostatistics at Harvard Medical School studied 681 male twins from the National Academy of Sciences-National Research Council World War II Veteran Twin Registry. According to Johanna M. Seddon, M.D., director of the Epidemiology Unit at the Massachusetts Eye and Ear Infirmary and an associate professor of ophthalmology at Harvard Medical School, and investigator, “We ... found that increased intake of fish reduced the risk of macular degeneration (AMD) , particularly if they ate two more servings per week. Dietary omega-3 fatty intake was also inversely associated with AMD. This observational study of twins provides further evidence that cigarette smoking increases risk while fish consumption and omega-3 fatty acid intake reduce risk of AMD.”
Omega 3 Fatty Acids and Prevention of Macular DegenerationResearchers from Australia and Singapore published a study entitled, "Dietary Omega-3 Fatty Acid and Fish Intake in the Primary Prevention of Age-Related Macular Degeneration: A Systematic Review and Meta-analysis." This meta-analysis consisted of a mathematical evaluation of the results from nine previous studies of nearly 89,000 people, of which more than 3000 developed macular degeneration. The authors found that high dietary intake of fish oils was associated with a 38% reduction in the risk of late macular degeneration. Furthermore, people who ate fish twice weekly not only reduced their risk of late AMD, but also early AMD (soft drusen or retinal pigmentary changes). AREDS 2
Omega 3 research and macular degeneration continues today. Because of their apparent benefits, the National Eye Institute is currently performing the Age Related Eye Disease Study 2 (AREDS 2), which is looking at the benefits ofomega 3, and the carotenoids lutein and zeaxanthin.
