The omega-3 fatty acids DHA and EPA (docosahexaenoic and eicosapentaenoic acids, respectively) found in salmon may shield cell walls from free-radical damage caused by UV rays, according to a 2009 study in the American Journal of Clinical Nutrition. Researchers followed the eating habits of more than 1,100 Australian adults for approximately five years and found that for those who ate a little more than 5 ounces of omega-3-rich fish—such as salmon—each week the development of precancerous skin lesions decreased by almost 30 percent. Aim to eat two servings of fatty fish each week: not only are the omega-3s good for your skin, they’re good for your heart too.
