Seafood is very healthy to eat – all things considered. Fish and shellfish are an important source of protein, vitamins and minerals, and they are low in saturated fat. But seafood’s claim to fame is its omega-3 fatty acids, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), all of which are beneficial to health. The U.S. Dietary Guidelines for Americans strongly suggest that adults eat two servings of seafood, or a total of eight ounces, per week.
