Fish, olive oil, nuts good for eyes too, more studies find

Consuming healthy fats reduce risk of age-related macular degeneration. AMD is the top cause of blindness among people over 65 living in developed world. Risk factors for AMD are age, genes, and smoking. People who ate the most trans fat had higher risk of AMD .

Studies from two different teams published Monday in the Archives of Ophthalmology provide more evidence that fish, olive oil, and nuts -- which contain healthy fats -- can reduce the risk of developing a retina-destroying condition known as age-related macular degeneration (AMD).

The studies aren't the first to suggest fish and omega-3 fatty acids may help protect vision; in fact, the first findings pointing in this direction are more than a decade old. But experts not involved in the research agree that the new studies are well done and rigorous.
