Crohn's Disease Exclusion Diet

Professor Arie Levine from Wolson Medical Center in Israel discussing the diet:

Link to the currently recruiting study:

Previously completed trial (12-week prospective trial of children with mild to moderate CD)
CDED plus PEN was better tolerated than EEN in children with mild to moderate CD. Both diets were effective in inducing remission by week 6. The combination CDED plus PEN induced sustained remission in a significantly higher proportion of patients than EEN, and produced changes in the fecal microbiome associated with remission.

I spent lots of time searching, but it is almost impossible to find any documentation with details about the composition of the diet. Strangely enough a patent was submitted for the diet (currently pending) and information was disclosed:

The diet consists of two stages. The first one lasting 6 weeks, and the second stage continuing for another 6.
