Summary of the various dietary treatments for IBD other than EEN

Diet	Composition and rationales of the diet	Literatures
Specific carbohydrate diet	Diet originally developed for Celiac disease which excludes complex carbohydrates and processed foods to improve intestinal inflammation by restoring microbial diversity	Case series
		Prospective studies
		Retrospective studies
CD-TREAT diet	Individualized and revised version of EEN that mimics the composition of EEN using ordinary food	Prospective study
Crohn disease exclusion diet	Avoidance of sauces except some specific spices and herbs, gluten, dairy products, gluten free baked goods and breads, animal fat, processed meats, food products containing emulsifiers, canned goods, and all packaged products which hypothetically affect the microbiome or intestinal permeability.	Observational studies
		Prospective studies
IBD-AID (anti-inflammatory diet)	A nutritional regimen as an adjunctive dietary therapy for IBD that restricts the intake of certain carbohydrates, but includes pre- and probiotic food, modified dietary fatty acids and food texture	Retrospective case series
IgG4 exclusion diet	Diet excluding food with high IgG4 titer	RCTs
Low FODMAP diet	Avoidance of poorly absorbed short-chain carbohydrates in order to elude bacterial fermentation or water shedding into the lumen	Pilot study
		RCTs

IBD, inflammatory bowel disease; EEN, exclusive enteral nutrition; CD-TREAT, Crohn's disease treatment-with-eating; IBD-AID, inflammatory bowel disease-anti inflammatory diet; FODMAP, fermentable oligo-,di-,monosaccharides and polyols; RCT, randomized controlled trial.
