Eating foods rich in omega-3 fatty acids, such as salmon and tuna, seems to be fine for not only the heart and mind but the eyes. A latest study adds shellfish to that group. It found that seniors who ate at least one serving a week of fish or shellfish high in omega-3s reduced their risk of developing advanced age-related macular degeneration, a disease that affects vision, by 60 percent.

The findings are consistent with mounting proof that high levels of dietary omega-3 fatty acids benefit eye health, the researchers said.

"But, unlike earlier studies, we included shellfish intake in the determination of omega-3 fatty acid consumption," said researcher Bonnielin K. Swenor of the Wilmer Eye Institute at John Hopkins University. "This is main because shellfish, particularly crab and oysters, are a main component of the diet" of the study population.
