Diet Rich in DHA and EPA May Protect Against Age-Related Macular Degeneration Progression

In a prospective study involving 2,924 eligible AREDS (Age-Related Eye Disease Study) AMD (age-related macular degeneration) trial participants, results indicate that consumption of a diet rich in DHA may reduce progression of AMD. After adjusting for potential confounders, including AREDS supplementation, higher intakes of DHA (>/= 64 mg/d) and EPA (>/= 42.3 mg/d), and reducing dietary glycemic index (< 75.2) were associated with 27%, 26%, and 24% reduced risks for progression to advanced AMD, respectively. Thus, the authors of this study conclude, "Our findings show an association of consuming a diet rich in DHA with lower progression of early AMD. In addition to the AREDS supplement, lower dGI with higher intakes of DHA and EPA was associated with reduced progression to advanced AMD."
