The Best Sustainable Fish Sources of Omega-3s

Just about the time the idea that seafood was heart-healthy had become widely understood, the sustainability issue crept into the picture. Some of the fish that rate high on ecofriendly lists (tilapia, for instance) are also among the lowest in omega-3 fatty acids. But don't give up just yet and look to, say, nuts for all your good fats. Fish is the best source of two important types of omega-3s, DHA and EPA. The fish mentioned here provide two to six times a daily dose, and they're great sustainable options, as well.
