Atrial fibrillation is a common type of arrhythmia in the elderly. After being diagnosed with atrial fibrillation, there are indeed some dietary considerations to be aware of. Here are a few aspects to pay attention to: First, eat less spicy and greasy food. Spicy and greasy foods can often irritate our stomach, leading to discomfort and potentially triggering an episode of atrial fibrillation. Second, eat more vegetables and fruits. Vegetables and fruits are often rich in dietary fiber and vitamin C, which are beneficial to our health. Third, balance meat and vegetable intake and ensure nutritional balance. Foods such as pork, fish, and lean meats are rich in high-quality protein, which is beneficial for our health.
