Dietary fatty acids and the 10-year incidence of age-related macular degeneration: the Blue Mountains Eye Study.
Arch Ophthalmol 2009; 127(5):656-65AO

Abstract

OBJECTIVE

To assess the relationship between baseline dietary fatty acids and 10-year incident age-related macular degeneration (AMD).

METHODS

In an elderly Australian cohort, 3654 participants were examined at baseline and 2454 were examined 5 and/or 10 years later. We assessed AMD from retinal photographs. Participants completed a semiquantitative food frequency questionnaire.

RESULTS

After adjusting for age, sex, and smoking, 1 serving of fish per week was associated with reduced risk of incident early AMD (relative risk, 0.69 [95% confidence interval, 0.49-0.98]), primarily among participants with less than the median linoleic acid consumption (0.57 [0.36-0.89]). Findings were similar for intake of long-chain omega-3 polyunsaturated fatty acids. One to 2 servings of nuts per week was associated with reduced risk of incident early AMD (relative risk, 0.65 [95% confidence interval, 0.47-0.91]). Protective associations between the intake of nuts and reduced risk of pigmentary abnormalities were seen among nonsmokers, participants with less than the median ratio of serum total to high-density lipoprotein cholesterol, and those with beta carotene intake greater than the median level.

CONCLUSIONS

This study provides evidence of protection against early AMD from regularly eating fish, greater consumption of omega-3 polyunsaturated fatty acids, and low intakes of foods rich in linoleic acid. Regular consumption of nuts may also reduce AMD risk. Joint effects from multiple factors are suggested.
