When there is inflammation or a foreign body in the airway, it stimulates the nerves of the respiratory mucosa, which will be transmitted to the cough center, which will then give instructions to complete the coughing action through the respiratory machine and the airway, with the cooperation of the birth gate. Foreign bodies, or pathogenic microorganisms, can be removed from the airway through coughing to achieve the self-purification function of the respiratory tract. Seafood is a food that is rich in protein, and eating seafood allows the body to be exposed to this foreign protein. Some patients are allergic to seafood and are prone to airway mucosal inflammation due to seafood irritation, which in turn can aggravate the cough. Therefore, in general, during the acute phase of a cough attack, it is recommended that the patient’s food should be as light as possible, especially for patients with a history of dry cough and allergies. Therefore, it is not recommended to eat seafood during coughing. Therefore, it is not recommended to eat seafood during coughing, but to eat light cereals, vegetables and fruits as much as possible.
