title: Dietary and socio-economic factors in relation to Helicobacter pylori re-infection.
abstract: OBJECTIVE
  To examine if dietary and socio-economic factors contribute to Helicobacter pylori (H pylori) re-infection.
  
  
  METHODS
  The population of patients consisted of subjects in whom H pylori infection had been successfully treated in the past. Patients were divided into two groups: I-examined group (111 persons with H pylori re-infection) and II-control group (175 persons who had not been re-infected). The respondents were interviewed retrospectively on their dietary habits and socio-economic factors.
  
  
  RESULTS
  A statistically significant lower frequency of fermented dairy products (P < 0.0001), vegetables (P = 0.02), and fruit (P = 0.008) consumption was noted among patients with H pylori re-infection as compared to those who had not been re-infected.
  
  
  CONCLUSIONS
  High dietary intake of probiotic bacteria, mainly Lactobacillus, and antioxidants, mainly vitamin C (contained in fruit and vegetables), might decrease the risk of H pylori re-infection.
