Finding sustainable seafood has always been about balancing the health of a given fishery with the health effects of consuming that fish. Some that can be sourced sustainably are also high enough on the food chain that they accumulate toxins in their flesh, transferring those to us humans when we eat them.
The Super Green List from the Monterey Bay Aquarium's Seafood Watch program balances the two considerations, providing a list of the healthiest seafood that comes from sustainable sources. First on the list: Albacore tuna that's troll- or pole-caught, from the U.S. or British Columbia.
