Eating Fish, Nuts And Olive Oil May Be Associated With Reduced Risk Of Age-related Blindness
"Regularly eating fish, nuts, olive oil and other foods containing omega-three fatty acids and avoiding trans fats appears to be associated with a lower risk for the eye disease age-related macular degeneration, according to two new reports."
After adjusting for age, sex and smoking, eating one serving of fish per week was associated with a 31 percent lower risk of developing early AMD. The association was stronger among individuals with a lower intake of linoleic acid, an unsaturated omega-6 fatty acid found primarily in vegetable oils. Eating one to two servings of nuts per week was associated with a 35 percent lower risk of early AMD.
"In conclusion, our findings support the hypothesis that increased intake of omega-three polyunsaturated fatty acids and regular consumption of fish and/or nuts in the diet may protect against the development of early AMD," the authors write. These fatty acids may protect the eyes by preventing the buildup of plaque in the arteries or reducing inflammation, blood vessel formation and oxygen-related cell damage in the retina.
