I might be a bit biased, but I do believe that eating seafood is really important (and delicious) way to boost your health. It is high in protein, low in saturated fat and high in omega-3 fatty acids. Our bodies need omega-3s, especially the long-chain omega-3s that are pretty much only found in seafood.
The Monterey Bay Aquarium states, “The nutritional profile of seafood makes it an important part of a healthy diet. Many types of seafood are high in long-chain omega-3 fatty acids, which play a crucial role in brain development in utero and during infancy, and for heart health in adults. This makes seafood consumption important for all adults, and especially important for pregnant or nursing women, young children and women of childbearing age (Oken et al., 2005; Golding etal., 2009).” from http://www.montereybayaquarium.org, Turning the Tide: The State of Seafood Report.
Even if you think you can’t afford to eat the recommended 3 servings of fish a week, there are some really easy, cheap ways to get seafood into your diet. Canned tuna, or even better, salmon, are pretty simple and tasty. (my list of favorite sites for recipes is in the sidebar)
I know there has been some nervousness in the last few years regarding mercury in seafood. Some people cut back their fish consumption for fear of contamination, but only certain fish need to be avoided. The Monterey Bay Aquarium has a cheat sheet you can print out and carry in your wallet or purse that tells you which types of seafood are the least contaminated. Wild Alaskan seafood has very little contaminants in it because the waters are less polluted. Alaskan salmon has almost no mercury in it, partly because they don’t live long, and they are pretty far down on the food chain.
