Objective: The incidence of gastroesophageal reflux disease (GERD) is increasing, and the disease has a close association with dietary habits. This study aims to investigate the role of tea and coffee drinking in the development of GERD. Materials and Methods: This study prospectively enrolled individuals who underwent an upper gastrointestinal endoscopy during a health checkup. Each participant completed the reflux disease questionnaire (RDQ). Coffee or tea drinking was defined as drinking the beverage at least 4 days/week for 3 months. Heavy coffee or tea consumption was defined as drinking at least two cups every day. Results: A total of 1837 participants (970 men; age 51.57 ± 10.21 years), who had data on clinical characteristics and consumption of coffee and tea with or without additives such as milk or sugar were included for final analysis. Among them, 467 (25.4%) were diagnosed as having symptomatic GERD based on the RDQ score, and 427 (23.2%) had erosive esophagitis (EE) on endoscopy. Drinking coffee or tea was not associated with reflux symptoms or EE in univariate and multivariate analyses. In contrast, drinking coffee with milk was associated with reflux symptoms and drinking “tea and coffee” was associated with EE in univariate analysis. However, these associations became insignificant after multivariate analysis. Conclusion: Drinking coffee or tea and adding milk or sugar was not associated with reflux symptoms or EE.
