title: [Preliminary clinical study on the correlation between allergic rhinitis and food factors].
abstract: OBJECTIVE
  To study the correlation between the onset of allergic rhinitis(AR) and food factors.
  
  
  METHODS
  All participants involving 101 patients with AR(10 cases accompanied with asthma) and 112 patients with nonallergic rhinitis(NAR) were studied in the form of prevalence survey. The components of food such as fat, salt and sugar intake were estimated through a food frequency questionnaire completed by the patients and controls. Scores were obtained depended on the food components. Histamine, dispensed in different concentrations, was dropped in the inferior turbinate to detect the nasal hyperreactivity(NH).
  
  
  RESULTS
  A significant difference (P < 0.05) was found between the food scores in AR and NAR groups. There was a greater significant difference (P < 0.01) between AR and NAR groups in NH. There was a negative correlation between food scores and histamine dosage both in AR group and AR and NAR group (P < 0.05).
  
  
  CONCLUSIONS
  There is a correlation between the onset of AR and the food factors. The more the fat, salt and sugar are contained in the food, the more obvious the NH is.
