Purulent tonsillitis is a relatively common otolaryngological disease, mainly caused by acute bacterial infection. Common fruits such as bananas, grapes, kiwis, and dragon fruits can be eaten because these fruits contain rich vitamins and have no irritant effects, thus they will not aggravate the condition of tonsillitis or affect the specific treatment outcome. After medication and dietary adjustment, the condition generally gradually eases. The treatment period is about a week. During the treatment, it is necessary to revisit regularly to observe the recovery situation.
