Eating foods rich in omega-3 fatty acids, such as salmon and
tuna, seems to be good for not only the heart and mind but the
eyes. A new 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 evidence
that high levels of dietary omega-3 fatty acids benefit eye
health, the researchers said. "But, unlike previous 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
important because shellfish, particularly crab and oysters, are
a main component of the diet" of the study population. Age-
related macular degeneration (AMD ) is a chronic and
irreversible condition that kills the cells in the macula, the
part of the eye responsible for seei
