In general, there is no dietary contraindication for interstitial pneumonia, so there is no food (including vegetables) that cannot be eaten in interstitial pneumonia. Interstitial pneumonia is an inflammatory and fibrotic disease of the interstitium of the lungs caused by a variety of reasons, the lesions mainly invade the interstitium of the lungs and the alveolar cavities, and ultimately cause fibrosis of the interstitium of the lungs, most of which are of unknown etiology, and it is a respiratory disease that is more common in the clinic. In patients with interstitial pneumonia, there are no food contraindications in the absence of allergies. Common foods such as beef, which has a high protein content, can provide the body with a large amount of high-quality protein, and vegetables in the food are also rich in vitamins, fiber and mineral elements, which are also beneficial to the recovery of this type of patients. If diagnosed with interstitial pneumonia, it is recommended to visit the respiratory medicine department regularly and standardize the treatment under the guidance of the doctor to avoid delays.
