There's some misunderstanding over the Shen diet. Yes, he does offer it up, but to his problem pouch patients of most, I think, have chronic pouchitis. Those of us who don't have chronic pouchitis eat a varied diet. I've had pouchitis once in 12 years, I don't plan on following the Paleo or FODMAP for once incidence. If you feel bad, there's no harm in trying this. Certainly everyone, colon or no colon, has foods that may affect them adversely.
