Food and Drink Guidelines for Managing Atrial Fibrillation (AFib)

Foods to Prioritize

• Fruits and vegetables:
  Aim for a rainbow of fruits and vegetables each day. They are full of vitamins, minerals, fiber, and antioxidants, and are naturally low in saturated fat and cholesterol.

• Whole grains:
  Choose options such as oats, brown rice, barley, and quinoa. These grains are rich in fiber and complex carbohydrates that provide steady energy.

• Legumes, nuts, and seeds:
  Beans, lentils, nuts, and seeds supply plant-based protein, healthy fats, and fiber. Regular nut consumption has even been linked to a lower risk of AFib.

• Lean proteins:
  Select skinless poultry, fatty fish like salmon or tuna (rich in omega-3s), and legumes to meet your protein needs.

• Healthy fats:
  Incorporate sources of unsaturated fats such as extra-virgin olive oil, avocado, and flaxseed into your meals.

Foods and Beverages to Limit or Avoid

• Alcohol:
  Alcohol is a common trigger for AFib and can disrupt your heart’s rhythm by affecting electrolyte balance. It’s best to limit it—or skip it entirely—if you experience frequent episodes.

• Caffeine:
  Caffeine’s impact on AFib varies from person to person. While some tolerate moderate coffee or tea, others may notice symptoms worsen. Pay attention to your body’s response, and avoid energy drinks, which are high in caffeine and stimulants.

• Processed and sugary foods:
  Packaged snacks, sodas, and sugary baked goods can contribute to conditions like obesity, high blood pressure, and diabetes—all of which increase AFib risk.

• High-sodium foods:
  Too much sodium can raise blood pressure, a known AFib trigger. Keep your salt intake in check, especially if your daily consumption tends to exceed 6g.

• Fried foods and fatty meats:
  Greasy, heavily processed meats and fried foods can raise cholesterol and blood pressure. Replace them with lean cuts of meat or plant-based proteins.

Key Minerals

• Potassium and magnesium:
  These minerals are essential for maintaining normal heart rhythm. Potassium is found in bananas, oranges, spinach, and potatoes, while magnesium is abundant in whole grains, nuts, beans, and leafy greens. Avoid taking potassium supplements unless recommended by your doctor.

Additional Tips

• Stay hydrated:
  Even mild dehydration can set off AFib episodes, so make water your go-to beverage.

• Manage weight:
  If you are overweight, gradual weight loss can reduce the frequency and severity of AFib symptoms.

• Know your triggers:
  Everyone is different. Keeping a food journal can help identify patterns between certain foods and symptom flare-ups. Review these findings with your doctor or dietitian.

Be mindful of medication interactions:

Some AFib medications—especially blood thinners—can interact with foods rich in Vitamin K, such as dark leafy greens. Talk to your healthcare provider before making major changes to your diet.
