When a 5-year-old child has tonsillitis and lacks appetite, in addition to regular treatment, their diet should be given sufficient attention. It is generally recommended that children eat more nutritious fruits and vegetables, such as pears, watermelons, tangerines, pomegranates, green leafy vegetables, and tomatoes. At the same time, the diet should be easy to digest and swallow, mainly consisting of thin porridge and soft cooked noodles. Additionally, avoid giving the child spicy and irritating foods like spicy hotpot, as well as beef, mutton, seafood, and other stimulating foods. Tonsillitis may cause some complications that are harmful to the child’s health, so parents must help the child receive proper treatment and pay attention to dietary adjustments.
