Why: Much seafood, especially salmon, contains omega-3 fatty acids,
which are proven to help prevent heart disease as we age. A study found
that younger women who didn't eat fish and other sources of omega-3s had the highest
risk of developing heart conditions.
Look for: Oily fish like sardines, anchovies, or rainbow trout,
which contain the highest levels of omega-3. Eat two servings of the fish
per week for a heart-healthy benefit. If you don't eat seafood, try these
fish-free sources of omega-3s.
