Studied in Children/Adults	Both	Children	Adults	Adults	Both	Studies on Maintenance Phase are in progress.
Studied in Ulcerative Colitis (UC) / Crohn's Disease (CD)	Both	Both	Both	Both	CD only	CD only
Stages/Phases	Intro diet for up to 5 days. No other required stages, although some foods like beans/lentils are advanced. Pecanbread website has suggested stages for those wishing to follow them when symptomatic.	Intro diet for up to 5 days. Typically, strict SCD is done before modified SCD is attempted.	Three phases defined based on level of symptoms: Phase 1: Basics, Phase 2: Introduction of more foods/textures, Phase 3: Remission.	Elimination Phase (minimum of 30 days), Reintroduction Phase, and Maintenance Phase.	Induction Phase consists of two 6-week phases with a food-list associated with each phase. Induction Phase is followed by the Maintenance Phase.	Maintenance phase is the last phase of the diet and requires 5 contiguous days following the diet as defined, which then can be followed with a max of 2 contiguous days with 2 free meals per week. Free meals can deviate from the diet with some restrictions. Maintenance phase is preceded by the Induction Phase.
Allowed Deviation from Diet	100% strict until 1 or 2 years of sustained remission.	100% strict until in sustained remission for a year or two.	Diet aims for 80% compliance or above, but better results may come with better compliance.	100% strict in the Elimination Phase, which lasts a few months or more as needed. Reintroduction Phase allows adding back of foods as tolerated.	100% strict in the Induction Phase.	In the Maintenance Phase, four free meals a week are allowed, in which other foods can be consumed (with some restrictions).
Limits Amounts of Foods	No	Yes for the new additions (sweet potatoes, rice, oats, cocoa, and maple syrup)	No	Yes for fruits	Yes	Yes
Mandatory Foods	No	No	IBD-AID Essential 8 - mandatory amounts of certain food types should be targeted per day.	No	Yes	No
Length of Time in Use	Long Time First described by Dr. Haas in 1924 and expanded and popularized by Elaine Gottschall for more common use in IBD. First study published in 2014.	New Still in ongoing study.	Relatively New First study published in 2014, ongoing studies include one in pregnant women.	Relatively New 2010: AIP first appeared as a brief list of foods to avoid in addition to standard Paleo for autoimmune disease in the book The Paleo Solution by Robb Wolf and on the website The Paleo Diet by Loren Cordain, refined later by Sarah Ballantyne. First study in IBD published in 2017.	Relatively New First study published in 2014.	New Studies on the Maintenance Phase are still ongoing.
