Purulent tonsillitis is an acute purulent infection of the tonsils, with relatively severe clinical symptoms, mainly manifested as severe pain in the throat, difficulty swallowing, and even systemic symptoms such as fever. Therefore, it is necessary to be cautious about diet in cases of purulent tonsillitis, mainly as follows: Firstly, avoid irritants like smoking, alcohol, and spicy foods such as chili peppers. Secondly, food should be neither too cold nor too hot, to avoid stimulating the tonsils and exacerbating the inflammation. Also, some fruits, like mangoes and pineapples, may cause allergies and can irritate the inflamed tonsillar tissue, worsening the condition. Therefore, these are the precautions that need to be taken.
