Atrial fibrillation of AFib is a condition that causes rapid or irregular beating in the upper chambers of the heart. This is a type of arrhythmia or irregular heartbeat that can result in a stroke and other heart-related issues if left untreated. The condition can be managed by making several lifestyle changes, including better nutrition. Food is a key component of health and can help avoid a variety of illnesses.  Foods to avoid with atrial fibrillation Caffeine Excessive intake of caffeine can quicken the heartbeat and induce premature heartbeats. Caffeine intake should be reduced to avoid triggering AFib. To avoid accidentally choosing caffeinated foods and drinks, one should read the labels, especially for beverages like sodas, tea, and herbal supplements, to check for caffeine. One can limit the amount of coffee they have in the day if it cannot be eliminated entirely. Salt Excessive salt intake raises blood pressure and increases the risk of AFib. So, people with hypertension, AFib, or sleep apnea should monitor and limit their sodium intake. Although salt is a common ingredient in foods, switching to less processed foods and using sodium-free seasoning can help reduce the daily salt intake. One should also avoid foods with high salt content, such as pizza, soups, burritos, and tacos.
