You know you're supposed to eat more fish (and less red meat). You've heard that including fish in your diet offers amazing health benefits from the essential fatty acids they contain in their lean meats. Plus, you love Emeril's Portuguese fish stew.

But you also know that fish present their own array of complex environmental and health concerns, from mercury contamination to over-fishing to the emissions associated with long-distance transport.

How can you know from one day to the next what's safe and what's not when it comes to reaping the potential health benefits of a diet rich in fish?

The Environmental Defense Fund has published a very useful comprehensive guide to fish, including the eco-best, the eco-okay, and the eco-worst. The site also offers an in-depth explanation of how the Defense Fund determines the ratings, as well as other extremely useful fish facts, from how to choose a safe fish oil supplement to the basic health benefits of eating fish in the first place.
