BACKGROUND: Dietary management of patients with inflammatory bowel disease (IBD) involves more than defining a therapeutic diet. The profusion of 'expert advice' is not necessarily built on evidence.
AIMS: To provide evidence-based guidance on all clinically relevant aspects of nutritional and dietary management of patients with IBD.
METHODS: A comprehensive review of the published literature was made.
RESULTS: Four pillars of management should be considered in all patients. First, nutritional status should be optimised, since myopenia and visceral obesity are associated with poorer outcomes, which can be improved with attention to their correction. Accurate point-of-care measurement of body composition is advocated to identify problems, guide interventions and monitor outcomes. Second, exclusive enteral nutrition and the Crohn's Disease Exclusion Diet with partial enteral nutrition in reducing intestinal inflammation in patients with Crohn's disease have sufficient evidence to be advocated. Multiple other dietary approaches, while promising, have insufficient evidence to be recommended. Third, dietary approaches are important in symptomatic control in many non-inflammatory scenarios. Finally, guidance on following a healthy diet is fundamental to the general health of patients. Multiple approaches are advocated, but the optimal strategy is unclear. The precarious nutritional status of patients with IBD together with the risks of nutritional inadequacy and maladaptive eating behaviours associated with restrictive diets dictate involvement of expert dietitians in assessment and personalised delivery of dietary interventions.
CONCLUSIONS: Four pillars of nutritional management require specific assessment and interventional strategies that should be chosen by evidence. Optimal delivery requires the skills of a specialised dietitian.
