Diet and inflammatory bowel disease: The Asian Working Group guidelines

Indian J Gastroenterol. 2019 Jun;38(3):220-246. doi: 10.1007/s12664-019-00976-1. Epub 2019 Jul 27.


Introduction: These Asian Working Group guidelines on diet in inflammatory bowel disease (IBD) present a multidisciplinary focus on clinical nutrition in IBD in Asian countries.

Methodology: The guidelines are based on evidence from existing published literature; however, if objective data were lacking or inconclusive, expert opinion was considered. The conclusions and 38 recommendations have been subject to full peer review and a Delphi process in which uniformly positive responses (agree or strongly agree) were required.

Results: Diet has an important role in IBD pathogenesis, and an increase in the incidence of IBD in Asian countries has paralleled changes in the dietary patterns. The present consensus endeavors to address the following topics in relation to IBD: (i) role of diet in the pathogenesis; (ii) diet as a therapy; (iii) malnutrition and nutritional assessment of the patients; (iv) dietary recommendations; (v) nutritional rehabilitation; and (vi) nutrition in special situations like surgery, pregnancy, and lactation.

Conclusions: Available objective data to guide nutritional support and primary nutritional therapy in IBD are presented as 38 recommendations.
