OLDER adults who eat fatty fish at least once a week may have a lower risk of serious vision loss from age-related macular degeneration, according to a United States study.
The study by researchers at the Johns Hopkins University in Baltimore does not prove that eating fish cuts the risk of developing the advanced stages of age-related macular degeneration, or AMD.
But researcher Bonnielin Swenor said the findings add to evidence from previous studies showing that fish eaters tend to have lower rates of AMD than people who infrequently eat fish. The study, reported in the journal Ophthalmology, also supports the theory that omega-3 fatty acids - found in oily fish like salmon, mackerel and albacore tuna - may affect the development or progression of AMD.
"While the current research indicates that a diet rich in omega-3 fatty acids can reduce the risk of late AMD in some patients, more research is still necessary," Swenor said.
For the study, Swenor and her colleagues analyzed data from 2,520 adults aged 65 to 84 who underwent eye exams and completed detailed dietary questionnaires.
Fifteen percent were found to have early- or intermediate-stage AMD while just under 3 percent were in the advanced stage.
