Acute tonsillitis refers to acute inflammation of the tonsil mucosa and submucosa in the throat area, which may be related to bacterial infections, viral infections, and some physical and chemical factors, such as dust and high temperature. Therefore, it is advisable to avoid spicy and irritating foods in the case of acute tonsillitis. Instead, we can eat more bland, easily digestible, high-protein foods rich in vitamins, such as foods with a bitter taste. We can also consume some throat-clearing fruits like watermelon, dragon fruit, apple, and snow pear, etc. Thus, during the anti-inflammatory treatment for acute tonsillitis, one can also adopt a light diet.
