1. Understanding AFib and Its Impact on Diet

Atrial fibrillation (AFib) is a common heart condition characterized by an irregular and often rapid heart rate. This occurs when the upper chambers of the heart (atria) beat chaotically and out of sync with the lower chambers (ventricles). Managing AFib involves various lifestyle adjustments, including dietary modifications. Diet plays a pivotal role in controlling heart health, influencing factors like blood pressure, inflammation, and electrolyte balance, all of which can impact AFib episodes. Therefore, knowing what foods to avoid with AFib is essential.

1.1 How Diet Affects Heart Health in AFib Patients

A well-balanced diet can significantly reduce the risk of AFib episodes and improve overall heart health. Conversely, a diet high in processed foods, sugars, and unhealthy fats can exacerbate AFib symptoms. According to the American Heart Association, a heart-healthy diet should be low in sodium, saturated fats, and added sugars, while rich in fruits, vegetables, and whole grains. This approach helps maintain stable blood pressure, reduces inflammation, and supports regular heart function. Understanding these principles is the first step in identifying what foods to avoid with AFib.

1.2 Key Dietary Goals for Managing AFib
