Background
Barrett’s esophagus (BE) and esophagitis share potentially modifiable risk factors such as obesity, smoking, and alcohol. The role of diet on BE and esophagitis is still debated.
Aims
The objective of this study was to examine the association between some dietary habits and the risk of BE and esophagitis in Italy.
Methods
A multicenter case–control study involving 1285 individuals was carried out in 12 areas. Patients with a new diagnosis of BE (320) or esophagitis (359) and a group of endoscopic controls (606) were included. Information on personal history and dietary habits was collected using a structured questionnaire.
Results
No clear monotonic significant dose–response relationship was found for most of the considered food items. Nevertheless, the most extreme consumption category of red meat, cold cuts, dairy products, and fried foods showed esophagitis risk excesses varying from 19 to 49%. A higher fat rich diet seemed to increase risk by 49% for BE and 94% for esophagitis. A downward tendency in esophagitis (− 27%) and BE risk (− 20%) was found associated with higher frequency of fresh fruit intake. In addition, a statistically significant twofold increased risk for both BE and esophagitis was found for subjects eating late evening snacks more than once every three days in comparison with the lowest intake category (no consumption).
Conclusions
BE and esophagitis patients appeared to be more likely than controls to follow a diet rich in fats and poor in fruit and vegetables. Late evening snacks were found to be associated with both disorders.
