DEAR DOCTOR K: You've written that fatty fish like salmon are a good source of omega-3 fats. Does it matter whether the salmon is farmed or wild?
DEAR READER: Salmon and other fatty fish certainly are an excellent dietary source of omega-3 fatty acids, which lower the risk of heart disease. Many supermarkets offer both farmed and wild-caught salmon. The two types have noticeably different tastes and textures. Wild-caught also tends to be more expensive.
