Heart-Healthy Eating: Fish and Fish Oil

Fish is a lean protein source that contains omega-3 fatty acids. This type of fat can be part of a heart-healthy diet.

Fish oil supplements are another way to get omega-3 fatty acids. Research has not proved that fish oil is helpful for everyone. That's why doctors do not agree about whether these supplements can help protect your heart.

If you have severely high triglycerides, your doctor may recommend you take fish oil to try to prevent a problem with your pancreas called pancreatitis.
