Acute tonsillitis is primarily caused by an acute infectious inflammation of the tonsils due to bacterial infection, which may also initially involve viral infections. The main bacteria involved are Staphylococcus aureus and hemolytic streptococcus. The dietary restrictions for acute tonsillitis mainly include the following:

Firstly, in terms of diet, it is important to eat light, nutritious, and easily digestible foods. Spicy and stimulating foods such as tobacco and chili peppers should be avoided, as these irritants can cause further congestion and swelling of the mucous membranes, exacerbating the condition during the acute phase.

Secondly, attention should be given to substances such as mangoes and seafood, which can cause allergies. If a patient is allergic to these substances, consuming them can trigger allergic symptoms, aggravating the clinical symptoms of acute tonsillitis and worsening the condition.

Thirdly, it is important to ensure that the food consumed is neither too hot nor too cold, as extreme temperatures can affect the recovery from the illness.
