A substantial body of scientific study suggests that omega-3 fatty acids can help reduce the risk of heart disease. The best sources of these nutrients are certain fish, including albacore tuna, bluefish, lake trout, and salmons (Atlantic, pink, king). But if you're a vegetarian, or if you just don't like fish, there are other food sources of omega-3 fatty acids:

  • Leafy green vegetables (e.g., spinach)
  • Tofu
  • Ground flaxseed
  • Canola oils
  • Olive oils
  • Walnuts

As for fish oil capsules and supplements, the research is less definitive; more studies need to be done to establish whether these supplements are effective in reducing heart disease risk.
