If a child develops tonsillitis, the first dietary consideration is to maintain a light diet, focusing on vegetables and fruits, and supplementing vitamins and trace elements to boost immunity. It’s also important to choose foods that are easy to swallow and digest, such as porridge, and to drink plenty of water. Additionally, it’s advisable to avoid foods like lamb and dog meat. Parents should help their children develop good living habits, maintain a regular routine, exercise moderately, and enhance immunity to reduce the incidence of disease.
