Mayo Clinic on Omega-3 in fish: How eating fish helps your heart
The omega-3 fatty acids in fish are good for your heart. Find out how the heart-health benefits of eating fish usually outweigh any risks.
If you’re worried about heart disease — whether you want to avoid it, or you already have it and want to get healthier — eating one to two servings of fish a week could reduce your risk of dying of a heart attack by a third or more.
Doctors have long recognized that the unsaturated fats in fish, called omega-3 fatty acids, appear to reduce your risk of dying of heart disease. For many years, the American Heart Association has recommended that people eat fish rich in omega-3 fatty acids at least twice a week. But some people are still concerned about mercury or other contaminants in fish outweighing its heart-healthy benefits. However, when it comes to a healthier heart, the benefits of eating fish usually outweigh the possible risks of exposure to contaminants. Find out how to balance these concerns with adding a healthy amount of fish to your diet.
