Fish
Fish is also a great source of low-fat protein that can help with atrial fibrillation. This is especially true for cold water fish like mackerel, herring, and salmon. They are rich in omega-3 fatty acids which have been shown to ensure a healthy heart by reducing triglycerides, a type of fats in the blood. Make sure to include these foods in your diet at least 2 to 3 times per week. Also, you could get omega-3 fatty acids in canola oil, soybeans, walnuts, and flaxseed. [4]
