The Food and Drug Administration wants to urge women and children to eat more fish. The Environmental Protection Agency thinks that could be dangerous. What’s the best advice to follow when two federal titans clash?

The report contends that nutrients in fish, including omega-3 fats and selenium, are so crucial for childhood neurological development that the benefits outweigh risks.
