High sucrose and fast food intake increased Crohn's disease risk, while fiber intake decreased it. Fast food consumption was linked to higher risks for both Crohn's disease and ulcerative colitis.

Area of Science:

  • Gastroenterology
  • Epidemiology
  • Nutritional Science

Background:

  • Inflammatory bowel disease (IBD), encompassing Crohn's disease (CD) and ulcerative colitis (UC), represents a significant global health concern.
  • Dietary factors are increasingly recognized as potential modulators of IBD risk and progression.
  • Understanding the relationship between specific dietary habits and IBD is crucial for developing effective prevention and management strategies.

Purpose of the Study:

  • To investigate the association between dietary habits and the risk of developing inflammatory bowel disease (IBD).
  • To examine the specific roles of sucrose, fiber, fast food consumption, and coffee intake in relation to Crohn's disease and ulcerative colitis.

Main Methods:

  • A population-based case-control study was conducted in Stockholm between 1984 and 1987.

  • Retrospective dietary information was collected via postal questionnaires from 152 CD cases, 145 UC cases, and 305 controls, focusing on intake 5 years prior to the study.
  • Relative risks (RR) and 95% confidence intervals (CI) were calculated to assess the association between dietary factors and IBD.

    • Main Results:

    • High sucrose intake (≥55g/day) was associated with an increased risk of Crohn's disease (RR=2.6, 95% CI=1.4-5.0).
    • High fiber intake (≥15g/day) was associated with a decreased risk of Crohn's disease (RR=0.5, 95% CI=0.3-0.9).
    • Frequent fast food consumption (≥2 times/week) showed a significantly increased risk for both Crohn's disease (RR=3.4, 95% CI=1.3-9.3) and ulcerative colitis (RR=3.9, 95% CI=1.4-10.6). A potential protective effect of coffee was noted but considered an artifact.

    Conclusions:

    • Dietary patterns, particularly high sucrose and fast food consumption, appear to be associated with an elevated risk of developing Crohn's disease.
    • Increased fiber intake may confer a protective effect against Crohn's disease.
    • Fast food consumption is linked to increased risk for both major forms of inflammatory bowel disease, suggesting a need for dietary recommendations focusing on reduced intake of processed and fast foods.
