Abstract
Gastroesophageal reflux disease (GERD) is a common condition with a wide range of clinical manifestations. The clinical epidemiology of GERD is related to diet. It has been speculated that certain dietary factors may play a role in the pathogenesis or course of GERD. Physiological studies have shown a decrease in lower esophageal pressure and an increase in esophageal acid exposure in response to consuming a variety of foods. Subjects with GERD are sensitive to acidic juices, such as orange and tomato juices. Some patients are less tolerant to caffeine including coffee. Fatty foods and chocolate may weaken the lower esophageal sphincter, whereas protein may increase lower sphincter tone. Large meals distend the stomach, increase intragastric pressure, and facilitate gastroesophageal reflux. Alcohol consumption is another important risk factor for GERD. However, a wide-rangingreview of the available data revealed conflicting findings regarding the impact of dietary factors on GERD.(Korean J Med2016;90:93-97)
