Eating more fish may slow down the progression of macular degeneration. A new study based on the original AREDS (Age Related Eye Disease Study) data finds that eating cold water, fatty fish 1-2 times per week may reduce the advancement of macular degeneration.
Fatty fish include salmon, tuna, sardines, certain shellfish and herring. Two specific compounds, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), have been shown to be protective in the disease.
Omega 3 fatty acids have also been implicated in other studies.
What does this mean? These are really associations noted by researchers. This is not definitive proof that eating fish is helpful. Large, randomized cohort studies are needed to have definite proof.
