Fatty Fish Consumption is Associated with a Reduction in Macular Degeneration Risk
Data from the EUREYE study of 2,275 European adults over the age of 65 was evaluated to determine the relationship between fish consumption and Macular Degeneration risk. Fish intake during the previous 12 months was collected using a food frequency questionnaire. Analysis of this data found that fatty fish consumption once or twice per week was associated with a 58% reduction in risk for Neovascular Age-Related Macular Degeneration (NV-AMD). A comparison of the highest intakes of fatty fish to the lowest intakes of fatty fish found a larger 69% reduction in risk. No reduction in risk was found for non-oily white fish consumption.
This data further supports the belief that the consumption of DHA and EPA omega-3 fatty acids from fatty fish may significantly reduce the risk of macular degeneration. A minimum daily intake of 500 to 1,000 mg of total DHA/EPA was recommended by these researchers to experience these possible benefits.
