People with cough can eat popcorn in moderation if they are not allergic. The diet of cough patients advocates light and soft food, less greasy, spicy and harsh and rough food. Peaches are rich in water, vitamins and minerals. If you are not allergic to it, you can eat popcorn, which has no effect on the symptoms of coughing and provides the body with nutrients, which is beneficial to the recovery of the disease. However, as a fruit with a high sugar content, too much popcorn may aggravate the cough, so it is necessary to eat popcorn in moderation. If you have a recurrent cough, you need to identify the cause of the cough and treat it. Avoid exposure to irritating gases, cold and exertion, and eat a well-balanced diet.
