Evidence supports the benefits of fish consumption during pregnancy, primarily because of the effects of n-3 polyunsaturated fatty acids on the neurodevelopment of the fetus. Many fish may also be potent sources of methylmercury and polychlorinated biphenol exposure, which have been shown to have severe negative impacts on both the mother and fetus. Therefore, all women of childbearing age should be informed of both the benefits and risks of fish consumption.
