Decide your salmon choices: farm-raised or wild? It's a tough issue: with wild salmon selling for up to $25 a pound out of season, it's hard to justify recommending it. If you're concerned about PCBs and other toxins in farmed salmon, be advised that most health experts agree that any risks are likely to be outweighed by the benefits of omega-3s in the fish. But environmental implications give us pause: the increase in salmon farms (400% in the past decade) have led to high concentrations of fish waste in the ocean. Some farms use more sustainable practices, but it's difficult to know what you're getting at the fish counter. Buy wild when you can afford it; prices are lowest mid-May through mid-September. If the choice is farmed or none at all, we defer to the health pros: go fish (whatever you can afford).
