(1) The diet of interstitial pneumonia should be avoided, and it should not be carried out blindly. Usually eat less spicy, fried and other irritating greasy foods: usually the diet is light, especially for obese patients, and the fat supply is appropriate. Lean meat should be eaten to achieve the purpose of resolving phlegm and properly controlling weight. Spicy, fried and other foods, because it is easy to produce phlegm, lead to heat to help evil, and evil heat is depressed. Long-term treatment will lead to disease and heat invading the lungs, which will aggravate the condition.

(2) Drinking plenty of water is very helpful for the treatment of interstitial pneumonia. Because patients with severe interstitial pneumonia and pulmonary fibrosis often lose water due to breathing with their mouths open, sweating too much and eating too little, phlegm is sticky and difficult to cough up. Even if water is supplemented and fluid intake is increased, is it of great significance to correct or prevent water loss? Patients should be encouraged to drink more water; If the patient can't eat or drink water, intravenous rehydration can be used, which is beneficial to dilute sputum and promote phlegm discharge. Patients with heart failure should drink water in moderation.

(3) Patients with interstitial pneumonia must not smoke, drink or eat salty food. Because most patients with interstitial pneumonia and pulmonary fibrosis are accompanied by airway hyperresponsiveness, the stimulation of salty foods such as cigarettes and alcohol can easily trigger bronchial reactions and aggravate symptoms such as cough and asthma.
