Seafood is a high-protein, low-fat food that provides a range of health benefits. White-fleshed fish, in particular, is lower in fat than any other source of animal protein, and oily fish are high in omega-3 fatty acids, or the “good” fats. Since the human body can’t make significant amounts of these essential nutrients, fish are an important part of the diet. Also, fish are low in the “bad” fats commonly found in red meat, called omega-6 fatty acids.
