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, a new study suggests.
The findings, reported in the journal Ophthalmology, do not prove that eating fish cuts the risk of developing the advanced stages of age-related macular degeneration, or AMD.
But they add to evidence from previous studies showing that fish eaters tend to have lower rates of AMD than people who infrequently eat fish.
They also support the theory that omega-3 fatty acids — found most abundantly in oily fish like salmon, mackerel and albacore tuna — may affect the development or progression of AMD.
