Omega 3 and Vitamin D linked to lower risk of macular disease

Higher Intake Of Fish And Vitamin D Levels Linked To Lower Risk Of Age-related Macular Disease ScienceDaily 5/15 07 "Individuals who have higher dietary intake of foods with omega-3 fatty acids and higher fish consumption have a reduced risk of advanced age-related macular degeneration, while those with higher serum levels of vitamin D may have a reduced risk of the early stages of the disease..."Dietary total omega-3 long-chain polyunsaturated fatty acid intake was inversely associated with neovascular AMD, as was docosahexaenoic acid," or DHA, a fatty acid that previous evidence suggests affects the retina...Omega-3 fatty acids may influence processes involved in the development of blood vessel-- and nerve-related diseases of the retina, the authors write. For instance, DHA may protect the retina by influencing which genes turn on and off, while fatty acids overall may eventually form compounds that promote cell survival and proper blood vessel function, reduce inflammation and maintain energy balance..."Levels of serum vitamin D were inversely associated with early AMD but not advanced AMD," the authors write. When participants were split into five groups based on level of vitamin D in the blood, those in the highest group had a 40 percent lower risk of early AMD than those in the lowest group. "Milk intake was inversely associated with early AMD. Fish intake was inversely associated with advanced AMD."...Vitamin D may reduce the risk of AMD by reducing inflammation or by preventing the growth of new blood vessels in the retina, which contributes to some forms of AMD..."
