Walnuts contain Omega 3s.  Can a diet rich in Omega 3 fatty acids help our vision?  I found and interesting article (exerpt below) that discusses the positive nature of Omega 3 fatty acids when added to the diet of mice.  Now whether one study of mice is enough for us to add more Omega 3 to our diets is questionable.  However, there has been plenty of other research supporting many healthy benefits of Omega 3s.  So go ahead and have that Salmon – it is good for you.

The August 2009 issue of the American Journal of Pathology presents findings from a study conducted by the National Eye Institute in Bethesda, MD that examined the direct effect of omega-3 fatty acids on the prevention of age-related macular degeneration (AMD). The scientists found that mice fed a diet high in omega-3 fatty acids had slower progression of the leisons in the eye and some improvement. They also found that the mice had lower levels of inflammatory molecules and higher levels of anti-inflammatory molecules, which they suggest may explain their findings.
