Whooping cough is an acute respiratory infectious disease caused by infection with Bordetella pertussis, mainly characterized by paroxysmal spasmodic cough, crowing inspiratory noise, commonly seen in children. In terms of diet, children with whooping cough should eat light and nutritious food. Do not eat spicy, greasy, or cold foods, as spicy foods can irritate the tracheal mucosa, and cold or greasy foods can damage the spleen and stomach, potentially exacerbating inflammatory changes.
