Researchers from Harvard Medical Centre have found regular consumption of fish and omega-3 acids is associated with a reduced risk of women developing age-related macular degeneration (AMD).
The research, set to appear in the June issue of Archives of Ophthalmology, found an estimated nine million adults in the US aged over 40 show signs if AMD and an additional 7.3 million show signs of early age-related macular degeneration.
The researchers collected data on 38,022 women who had not been diagnosed with AMD and information their eating habits at the beginning of the study.
During the ten years of follow-ups, additional questionnaires tracked the women’s eye health, with a focus on the diagnosis of AMD.
Researchers diagnosed 235 cases of AMD and in analysis found women who consumed the most DHA (found in fish and omega-3) had a 38 per cent lower chance of developing AMD.
One more or servings of fish per week, compared to less than one per month, was found to be associated with a 42 per cent lower risk of AMD.
"In summary, these prospective data from a large population of women with no prior diagnosis of AMD indicate that regular consumption of DHA and EPA and fish significantly reduced the risk of incident AMD," the authors conclude.
