A confounding view here though is that even though seafood contains pollutants, the benefit of high omega-3 content in some species outweighs the negative effects of the pollutants. The key is find the combo of: - high omega-3-to-omega-6 fat ratio in the fish - short-lived fish (low bioaccumulation) That basically leaves you with wild salmon, (some) farmed salmon, and small/oily fishes (like sardines and some species of mackerel).
