Consuming fish has been linked to a myriad of health benefits, mostly due to omega-3 fatty acids, which have been associated with decreased risk of cancer and heart disease.

And according to a new study in the journal Ophthalmology, older adults eating fatty fish – such as salmon, mackerel, and albacore tuna – at least once a week may have a lower risk of age-related macular degeneration (AMD) leading to vision loss.

For the study, experts analyzed data from over 2,500 adults, ages 65 to 84, who completed dietary questionnaires and underwent eye exams; 15% were found to have early or intermediate-stage AMD and less than 3% had advanced AMD.

Researchers found participants with higher intake of fish rich in omega-3 fatty acids, consuming one or more servings a week, were 60% less likely to develop advanced AMD, than those consuming less than one serving per week.

However, the scientists insist this does not prove eating fish is directly linked to reduced risk of AMD.

But a major concern among fish eaters and non-fish eaters is mercury. Many fish consume pollutants laden with mercury, making them unsafe food choices. Fish like red snapper, shark, and Chilean sea bass are among the most contaminated.

Safer varieties of fish include: mussels, Alaskan salmon, rainbow trout, farmed clams, United States catfish, farmed oysters, stone crab, and Atlantic yellowfin tuna.
