foods to avoid when having cough
4. Avoid eating fried foods: Fried foods are oily in nature and oil is a well-known cough trigger. Deep-frying foods in hot oil generates a compound called acrolein, which acts as an allergen that aggravates coughing and causes throat itching. So, itâs best to avoid oily, fried foods while you have a cough. 5. Avoid smoking: Smoking is one of the causes of a cough due to bronchitis.
