What can pneumonia patients eat? Pneumonia is usually an acute illness, often accompanied by symptoms such as excessive phlegm, cough, shortness of breath, and chest pain, which demand strict dietary considerations. A good diet ensures that pneumonia patients get enough fluids and calories, which helps in the treatment of pneumonia. Patients can consume foods rich in quality protein, high calories, and vitamins, such as eggs, animal liver, cornmeal, buckwheat flour, and a moderate amount of fruits and vegetables. Foods like black fungus, seaweed, kelp, and mushrooms can also be included more frequently. It is important for patients to drink plenty of water. Pneumonia patients may experience fever and sweat a lot; drinking more water can help replenish fluids in a timely manner, prevent excessive loss of fluids, and more frequent urination helps in faster elimination of metabolic waste from the body, aiding in the recovery from the disease.
