Data analysis was performed by non-parametric tests.Results : The rate of Helicobacter pylori infection was ۴۲.۶% based on pathological examination (hematoxylin-eosin). Positive HP infection was inversely related to weekly consumption of fish (P = ۰.۰۰۹), green pepper (P = ۰.۰۱) and water (P = ۰.۰۱۹) and weekly consumption of tuna (P = ۰.۰۱۳) and tea (P = ۰.۰۴۸) was directly related. The severity of HP infection was inversely related to weekly consumption of fish (P = ۰.۰۰۱), green pepper (P = ۰.۰۴۵) and water (P = ۰.۰۰۱) and with weekly consumption of tuna (P = ۰.۰۱۱) and sugar (P = ۰.۰۴۴) was directly related.Conclusion : The results indicate the possibility of the effect of some foods such as fish (except tuna), green pepper and water on HP and the severity of this infection. Due to the limitations of this study, more comprehensive and accurate studies are necessary to prove the findings and achieve more details.
