Area of Science:

  • Gastroenterology
  • Nutritional Science
  • Epidemiology

Background:

  • Peptic ulcer disease (PUD) affects millions globally.
  • Dietary factors, including spice consumption, are investigated for their role in PUD.
  • Capsaicin, the active compound in chili, has known biological effects.

Purpose of the Study:

  • To investigate the association between chili consumption frequency and quantity and peptic ulcer disease.
  • To determine if chili intake differs between Chinese peptic ulcer patients and healthy controls.
  • To explore the potential protective role of chili use against PUD.

Main Methods:

  • A case-control study involving 103 Chinese peptic ulcer patients and 87 controls.
  • Standardized questionnaire to assess chili consumption habits.

  • Exclusion of participants who avoided chili due to symptoms or advice.
  • Multiple logistic regression analysis adjusted for age, sex, analgesic use, and smoking.

    • Main Results:

    • Peptic ulcer patients reported significantly lower median monthly chili use frequency (8 times) compared to controls (24 times) (P < 0.001).
    • Median monthly chili amount consumed was substantially lower in the ulcer group (312 units) versus the control group (834 units) (P < 0.001).
    • Higher chili intake (both frequency and amount) was associated with a reduced odds ratio (0.47) for peptic ulcer disease.

    Conclusions:

    • Chili consumption appears to have a protective effect against the development of peptic ulcer disease.
    • Lower intake of chili is associated with an increased risk of peptic ulcers.
    • Findings support the hypothesis that regular chili use may confer gastroprotection.
