Fish and shellfish can be an important part of a healthy diet, since they contain high-quality protein and beneficial fats. The omega-3 fatty acids found in cold-water fish are called essential fatty acids - we need to get them from foods because our bodies cannot manufacture them. Unfortunately some fish also contain high levels of mercury and other toxins.
The U.S. Environmental Protection Agency advises women of childbearing age and young children to abstain from eating shark, swordfish, king mackerel, and tilefish to avoid mercury poisoning. Fresh tuna also contains high levels of mercury. Canned tuna should be eaten no more than once a week; light tuna often has less mercury than albacore. Mercury can cross the placenta of pregnant women and affect the neural development of the fetus. In addition, it can be passed to an infant through breast milk.
