Fish curbs progress of serious eye disease

Two to three portions of fatty fish eaten weekly could help stave off progression of the age-related eye disease, macular degeneration, suggests research published ahead of print in the British Journal of Ophthalmology.
The researchers base their findings on almost 3,000 people, all of whom were taking part in a supplements trial, the Age Related Eye Disease Study.

They were monitored for the development of age-related macular degeneration over eight years.

Age-related macular degeneration, or AMD, is a progressive degenerative condition, which affects the back of the eye (macula). It robs people of the capacity to see fine detail, and eventually blinds them.

It is becoming much more common as the proportion of elderly in the world's population is steadily increasing. 

The trial results suggested that taking antioxidants plus minerals curbed progression of late stage, but not early, stage disease.
Participants were also quizzed about their diets, using a validated food frequency questionnaire, and they were periodically given general physical and eye exams.

The authors suggest that eating two to three servings of fatty fish, such as salmon, tuna, mackerel, shellfish, and herring every week, would achieve the recommended daily intake of omega 3, substantially cutting the risk of both early and late stage AMD.
