Many fish, especially oily, darker-fleshed fish like salmon and herring, are rich in heart-healthy, polyunsaturated, omega-3 fatty acids, but healthful fats are not the only reason to eat fish. Dietary guidelines in the United States encourage adults to eat eight ounces of a variety of fish and seafood each week – roughly two meals’ worth – because of the “total package of nutrients in fish,” which includes lean protein, vitamins A and D as well as B vitamins, and a host of minerals such as iron, iodine, selenium and zinc.
