Diets for inflammatory bowel disease: What do we know so far?

Area of Science:

• Gastroenterology
• Nutritional Science
• Immunology

Background:

• Diet significantly impacts inflammatory bowel disease (IBD) pathogenesis.
• Western diets are linked to increased IBD incidence, but specific factors remain unclear.
• Pro-inflammatory dietary components may alter immunity and gut microbiota, triggering IBD.

Purpose of the Study:

• To review existing literature on diet's role in IBD.
• To summarize scientific society recommendations for nutritional management of IBD patients.

Main Methods:

• Literature review of published data on diet and IBD.
• Analysis of clinical practice guidelines and consensus documents from scientific societies.

Main Results:

• Evidence quality is often low due to methodological limitations (small sample sizes, heterogeneity, lack of intervention studies).
• Dietary factors contributing to IBD development require further elucidation.
• Scientific societies have established consensus criteria for nutritional treatment in IBD.

Conclusions:

• Dietary interventions are crucial in managing IBD.
• Further high-quality research, including intervention studies, is needed to clarify diet-IBD relationships.
• Standardized recommendations are essential for consistent nutritional care in IBD.
