Salmon is good for healthy eyes and normal vision because it contains large amounts of omega-3 fatty acid -- more than any other type of fish or seafood. Studies suggest that people who have a higher intake of these fatty acids may be less likely to suffer from dry eyes.
Salmon is also good for the heart because those same fats help to reduce inflammation and keep cholesterol in check. The American Heart Association suggests you eat fatty fish at least two times each week.
Serve baked salmon for dinner, or use salmon chunks in salads and salmon patties. Salmon can also be served raw (like sushi or sashimi), or smoked with crackers.
