The aim of the study was to evaluate the influence of dietary and demographic factors and some habits on the prevalence of Helicobacter pylori infection in 150 dyspeptic patients examined endoscopically and by the urea breath test. Positivity rate was lower (50.6%) in patients consuming honey ≥1day weekly compared with the remainder (70.8%) and in those consuming green/black tea ≥1day weekly (45.2%) compared with the other patients (64.8%).
Logistic regression confirmed that the factors associated with significantly lower H. pylori positivity rate were the consumption of honey (odds ratio [OR], 0.38; 95% confidence interval [CI], 0.19-0.78) and green/black tea (OR, 0.45; 95% CI, 0.21-0.95).
In conclusion, honey and green/black tea intake is associated with reduced prevalence of H. pylori infection.
