Eating Fish Preserves Eyesight

Studies show that people who eat at least two servings of fish per week are less likely to develop age-related macular degeneration (AMD) -- a common cause of blindness among older people.

Age-related macular degeneration is the leading cause of irreversible vision loss among people over 65 in the U.S. The study also found that smokers nearly doubled their risk of the eye condition compared to people who never smoked.

The studies, which appeared in the Archives of Ophthalmology, reveal that those who ate a diet rich in omega-3 fatty acids found in fish were nearly 40% less likely to develop AMD. These omega-3 fatty acids are already known to help the heart and brain stay healthy.

Dr. Johanna Seddon of the Massachusetts Eye and Ear Infirmary in Boston, lead author of the U.S. study said “We have a longer life expectancy so the prevalence and burden related to age-related macular degeneration will continue to increase”.

Researchers from the Age-Related Disease Study Group in Rockville, Md., who conducted the study, say omega-3 fatty acids may reduce the risk of AMD in a variety of ways, such as promoting healthy blood vessel function, influencing which genes turn on and off, and reducing inflammation.
