One Fish, Two Fish, Blue Fish, Green Fish?
Omega-3's are good for you -- but not when they come with a side order of mercury and habitat destruction.
Co-op America's Safe Seafood Tip Sheet is the only source we know of that looks at both the health and environmental issues surrounding your fish choices. They compiled the best data on environmental sustainability from the Monterey Bay Aquarium, along with the Environmental Working Group's data on toxins, plus information from the FDA, EPA, and others, to create the most comprehensive safe seafood tipsheet around.
