Researchers looked at the effectiveness of fish oil in reducing the risk of heart attacks.
They found that 500 milligrams of omega-3 fatty acids a day will help protect healthy people against heart disease.
Those with a history of heart disease should aim for 800 to 1000 milligrams a day.
Healthy people can meet the recommendation by eating two meals a week that contain fish like salmon, trout or tuna.
Fish oil supplements are another way to get omega-3's into your diet.
But you should talk to your doctor first.
The guidelines are published in the Journal of the American College of Cardiology.
