Vision Support – Omega-3s Help!
ByOmega-3 Fatty Acids Protect Against Vision Loss
Omega-3 fatty acids found in fatty fish such as tuna and salmon may protect against progression of age-related macular degeneration, but the benefits appear to depend on the stage of disease and whether certain supplements are taken, researchers say.
The researchers calculated intakes of docosahexaenoic acid and eicosapentaenoic acid from dietary questionnaires administered to 2,924 men and women, ages 55 to 80, participating in an eight-year supplement trial, the Age-Related Eye Disease Study of the National Eye Institute.
The trial results suggest taking supplements of antioxidants plus zinc prevents progression of late-stage AMD.
The results, which are published online ahead of print in the British Journal of Ophthalmology, are in a report from researchers at the Laboratory for Nutrition and Vision Research, and Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University.
Eating two to three servings of fatty fish such as salmon, tuna, mackerel, shellfish, and herring every week would achieve the recommended daily intake of docosahexaenoic acid and eicosapentaenoic acid.
However, the majority of the study participants participants and Americans eat a much lower level than recommended.
“If changing dietary habits is not easy, supplementation is an option,” says corresponding author Chung-Jung Chiu.
