Nutrition in inflammatory bowel disease

Area of Science:

• Gastroenterology and Nutritional Science
• Pediatric Inflammatory Bowel Disease Research

Background:

• Inflammatory bowel disease (IBD) presents significant nutritional challenges, impacting growth and bone health in children.
• Disease-associated anorexia and the interplay between nutrition and cytokines are key areas of concern.
• Decreased bone mineral density is a recognized multifactorial complication requiring further research.

Purpose of the Study:

• To review recent advancements in understanding and managing nutritional complications in IBD.
• To highlight the role of nutrition in the pathogenesis of growth impairment in pediatric IBD.
• To discuss the therapeutic potential of specific nutrients and enteral nutrition in IBD management.

Main Methods:

• Literature review of recent developments in IBD nutrition.
• Analysis of in-vitro studies investigating nutrient-inflammation interactions.
• Examination of the role of enteral nutrition in Crohn's disease therapy.

Main Results:

• Improved understanding of anorexia and cytokine-nutrition interactions in pediatric IBD growth impairment.
• Recognition of decreased bone mineral density as a significant multifactorial complication.
• In-vitro elucidation of anti-inflammatory mechanisms of nutrients like n-3 fatty acids, antioxidants, and butyrate.

Conclusions:

• Enteral nutrition remains crucial for managing Crohn's disease.
• While in-vitro studies show promise for specific nutrients in ameliorating inflammation, clinical translation is pending.
• Further research is needed to bridge the gap between laboratory findings and clinical application for IBD nutritional therapy.
