Eating Lots Of Fish Plus Vitamin D Reduces Risk Of Age-related Macular Degeneration

A recent study has shown that omega 3 fatty acids can help reduce the risk of age-related macular degeneration (AMD).

There is currently no known way to prevent the condition, but research has begun to identify potentially modifiable risk factors and nutrient-based treatments.

The Research Group assessed 4,519 individuals aged between 60 to 80. Photographs were taken of their retinas to determine if they had AMD, and if so, to which of four stages the condition had progressed. The participants also completed a food frequency questionnaire that measured how often they consumed foods rich in certain vitamins, minerals and other nutrients, such as omega 3 fatty acids.

1,115 participants did not have any symptoms of AMD at the beginning of the study, and were compared with those who did. "Dietary total omega-3 long-chain polyunsaturated fatty acid intake was inversely associated with neovascular AMD, as was docosahexaenoic acid," or DHA, a fatty acid that previous evidence suggests affects the retina. Eating more than two medium (4-ounce) servings of fish per week or more than one medium serving of boiled or baked fish was associated with the lowest risk for advanced age-related macular degeneration.

Omega 3 fatty acids may influence processes involved in the development of blood vessel and nerve-related diseases of the retina.  DHA may protect the retina by influencing which genes turn on and off, while fatty acids overall may eventually form compounds that promote cell survival and proper blood vessel function, reduce inflammation and maintain energy balance.

"These results and those from other observational analytic investigations suggest that modifying diet to include more foods rich in omega-3 long-chain polyunsaturated fatty acids could result in a reduction in the risk of having neovascular AMD," .
