In two separate studies in the US and Australia, seniors who ate more fish were far less likely to develop age-related macular degeneration (AMD), the leading cause of vision loss for the elderly.
The U.S. study, which also found a link between cigarette smoking and AMD, found “that men with the highest fish consumption (at least two weekly servings) were 45 percent less likely to have AMD than those with the lowest fish consumption (less than one weekly serving).”
The Australian study involved over 2900 people aged 49 or older. This study found that “Participants who reported eating at least one weekly serving of fish were 40 percent less likely to develop early-stage AMD during the study, compared with those who reported eating fish less than once a month or not at all… People who ate fish frequently were also less likely to have late-stage AMD, the study shows. But that pattern was only seen in participants who reported eating fish at least three times weekly.”
If you have age-related macular degeneration, consider taking omega 3 fish oil supplements.
