Chronic Obstructive Pulmonary Disease (COPD) has no food contraindications without allergies, so there are no foods that patients with COPD cannot eat. Chronic Obstructive Pulmonary Disease (COPD) is a common lung disease in respiratory medicine, a chronic disease characterized by airflow obstruction, which can develop into respiratory failure and pulmonary heart disease, and has a high mortality and disability rate. There are no food taboos for patients with COPD, provided that they are not allergic.

If you are diagnosed with COPD, it is recommended that you go to the hospital as soon as possible and follow the doctor’s instructions for standardized treatment in order to avoid delays in your condition.
