Foods that are contraindicated during coughing need to be determined by the cause of the disease. Cough caused by pharyngitis, tonsillitis, etc., the patient should abstain from spicy and stimulating foods, smoking and alcohol, etc.; cough caused by allergic reactions, such as patients allergic to fish, shrimp, milk, etc., should avoid contact with allergy-inducing foods. Pharyngitis should not eat chili peppers, garlic and foods with high salt content, which will irritate the throat after consumption and easily cause sore throat. Foods with high salt content, such as soy sauce and salted vegetables, have a strong stimulating effect on pharyngitis. You should not eat spicy and stimulating foods such as chili peppers, ginger, garlic, etc. Consumption of these foods will aggravate the symptoms of tonsillitis. When allergic cough occurs, try not to eat fish, shrimp and other foods that can easily cause allergies. Patients with severe coughs are advised to go to the hospital in a timely manner to clarify the cause of the cough and follow the doctor’s instructions for medication.
