Omega-3 Fatty Acids Linked to Lower Risk of Eye Disease

Age-related macular degeneration (AMD) is an eye disease associated with aging that gradually destroys central vision, which is needed for seeing objects clearly and for common daily activities such as reading and driving.

According to two studies in the Archives of Ophthalmology, regular consumption of fish, nuts, olive oil, and other omega-3 fatty acid-containing foods appears to be associated with a lower risk of AMD.

In the first study, Australian researchers examined the retinal photographs of 2454 elderly participants at baseline, and again 5 and/or 10 years later. The participants were also asked to complete a food frequency questionnaire. The researchers found that participants who ate at least 1 serving of fish per week, or participants who consumed greater amounts of omega-3 fatty acids, seemed to have a reduced risk of AMD. Low intake of trans fats also seemed to protect against early AMD.

In the second study, another group of Australian researchers studied 6,734 participants aged 58 to 69 years of age to evaluate possible associations between past dietary fat intake and the prevalence of AMD. These researchers found that a diet low in trans fats and rich in omega-3 fatty acids and olive oil might reduce the risk of AMD.
