Introduction: Tonsillitis, an inflammation of the tonsils, can affect all ages but mainly occurs in children. Tonsils can be caused by infections or viruses. Consumption patterns are the actions of a person or group, notably individuals, in choosing what food to consume every day. Foods that contain oil, flavorings such as MSG (Monosodium Glutamate), and preservatives, when consumed in excess, will cause symptoms of itching or pain in the throat and will cause infection in the oral cavity, causing inflammation of the palatine tonsils. In addition, eating foods that are too cold, hot, sour, or spicy can irritate the pharyngeal and esophageal mucosa and trigger inflammation. This study aims to determine the relationship between eating habits and tonsillitis symptoms in children. Result: 120 respondents who stated that they were at risk, 74 people or 51.4% had tonsillitis symptoms, while 46 people or 31.9% did not have tonsillitis symptoms. Of the 24 respondents who stated that they were not at risk, 9 people, or 6.3%, had symptoms of tonsillitis, while 15 people, or 10.4%, did not have symptoms of tonsillitis. Conclusion: This indicates that the McNemar test results obtained at the first hypothesis (H1) are accepted due to the p-value of 0.000 (<0.05), indicating a substantial correlation between food consumption patterns and symptoms of tonsillitis in children.
