As part of a healthy diet, eat at least two servings of fish each week. Oily fish, which contain omega-3 fatty acids, are best. These fish include salmon, mackerel, lake trout, herring, and sardines.
Fish is an important part of a heart-healthy diet. A heart-healthy diet is not just for people who have existing health problems. It is good for all healthy adults and children older than age 2. Learning heart-healthy eating habits now can help prevent problems in years to come. Eating a heart-healthy diet can help you to:
Eating more than two servings of fish a week may lower your risk for stroke or TIA. Oily fish (such as salmon, mackerel, and herring) may lower your risk more than other types of fish.footnote 1
The U.S. Food and Drug Administration (FDA) and the U.S. Environmental Protection Agency (EPA) recommend that women who may become pregnant, pregnant women, nursing mothers, and young children should not eat shark, swordfish, king mackerel, marlin, orange roughy, bigeye tuna, or tilefish from the Gulf of Mexico, because these fish have higher mercury concentrations. But for middle-aged and older people, the protection fish offer the heart outweighs the risks of eating these fish. Eating a variety of fish may reduce the amount of mercury you eat.footnote 2
Sometimes people who don't eat fish take fish oil supplements. Some doctors think fish oil might help the heart because it has the omega-3 fatty acids from oily fish. But other doctors don't recommend these supplements to help the heart. That's because research has not proved that fish oil is helpful for everyone.footnote 3

If you don't eat fish, you can get omega-3 fats from foods such as omega-3 eggs, walnuts, flax seeds, and canola oil.
Most of these foods have a different kind of omega-3 fatty acid (called ALA) than the kinds of omega-3 fatty acids you get from eating oily fish (called DHA and EPA). There is not enough good research about whether foods with ALA help the heart.
