Patients with myocardial infarction can eat watermelon. Watermelon is a fruit, which contains a wealth of nutrients, including plant proteins, as well as notable amounts of glucose, sucrose, vitamins, dietary fiber, and minerals, essential for replenishing the human body's nutritional needs and hydration. Patients with myocardial infarction, if they do not have diabetes, may eat watermelon in moderation. However, they should not consume too much to avoid causing gastrointestinal discomfort and consequent distress. In daily life, patients should maintain a light diet and avoid fatty and spicy foods.
