The UMass diet is derived from the SCD and is the only diet purporting to be specifically designed for those with IBD, although the Paleo Diet has spun off at least one book for those with IBD. More on the UMass IBD diet here:

If you don't have the time to leaf through all the recipes in the second link, I actually did. The diet makes no sense to me, applying what I know about nutrition and what I know about IBD. I assume there is some science behind it and that UMASS is not employing knuckleheads, but you have to know that I am a graduate of UMass's rival UConn, so it is difficult for me to make such assumptions. LOL.
You really should take the time to educate yourself on this subject. I have tried to. I have spoken to multiple registered dieticians (one of whom is a client of mine) and medical doctors, in unison. I have read a few books. The books tend to have more subjective opinions than empirical, research-based science. Which is why I stopped reading them. But there is some science out there, you just have to look for it.
By the way I have had the J Pouch for 23 years and IBD for 43 years. When I was 9 years old they didn't have J Pouches, but they did when I was 29 and needed surgery. When I was 9 years old, they did not have much to treat UC and they did not have sedation of any kind for colonscopies. I have lived with UC and now Pouchitis/SIBO for the majority of my life, which is soon to be 52 years old.
