5. Tuna
Much like salmon, tuna is a vital part of a pescatarian or meat eating diet. Whether fresh or canned (if packed in water,) tuna is a low calorie yet high protein food that can be cooked in a wide variety of ways for a rich, filling meal. Tuna is also rich in the essential omega-3 fatty acids.
An important note: tuna is one of the fish most prone to bioaccumulating toxins like mercury and lead. Pregnant women should talk to their doctors about safe levels of tuna and other fish to consume. Always choose tuna packed in water, not oil, to reduce the fat content and sodium levels.
