Healthy seafood is becoming an increasingly complicated food item to buy. We may have lakes or rivers near our homes that experts tell us not to fish in because of the toxins in the fish. There are polluted areas around the globe with seafood and fresh water fish we are probably best to avoid. Many of us are also looking for seafood with healthy fats. As a general rule, seafood that is “wild” (as opposed to “farmed”) will have a healthier fat profile. In the graph at right, notice that the wild seafood has a higher ratio of Omega 3 to Omega 6 fatty acids, a ratio that supports brain and heart health. In many cases, wild fish will also have fewer pollutants.
But wild is not necessarily better from a sustainability point of view, an important factor if we want to continue to eat this great food. To help you navigate the complexities of seafood shopping, visit Monterey Bay Aquarium’s Seafood Watch and explore their seafood buying guide.
