Fish and omega-3 fatty acids

Fatty fish has high levels of omega-3 fatty acids, which can reduce your triglycerides — a type of fat found in blood — as well as reduce your blood pressure and risk of developing blood clots. In people who have already had heart attacks, omega-3 fatty acids may reduce the risk of sudden death.

Omega-3 fatty acids don't affect LDL cholesterol levels. But because of those acids' other heart benefits, the American Heart Association recommends eating at least two servings of fish a week. Baking or grilling the fish avoids adding unhealthy fats.

The highest levels of omega-3 fatty acids are in:

• Mackerel
• Herring
• Tuna
• Salmon
• Trout

Foods such as walnuts, flaxseed and canola oil also have small amounts of omega-3 fatty acids.

Omega-3 and fish oil supplements are available. Talk to your doctor before taking any supplements.
