Food-Based Approaches, Membership

Quality Rating

Criteria for starring system: 

  • Incorporates appropriate microbiome strategies
  • Incorporates appropriate gut healing strategies 
  • Inflammation reduction is a priority
  • Long-term symptom reduction
  • Easily implemented
  • Reduces disordered eating patterns

Caveat for starring system: This system is our opinion based on the available research at this time. We reserve the right to modify our recommendations as new literature is published and we learn more about the complexities of IBD. Review our recommendations with an appropriate amount of discretion and understand that oftentimes there is not a one size fits all approach for every situation.

LOFFLEX: Low Fat, Fiber, Limited Exclusion

Overview: Excludes foods high in fat and fiber designed to help Crohn’s Disease patients transition from a liquid diet and remain in remission.

  • For at least two weeks after a liquid diet, it is recommended to have only foods that are low in fat and fiber as well as those that trigger symptoms. This reintroduction process was developed as a way for researchers to speed up the reintroduction phase after a liquid diet and determine a list of foods patients could safely incorporate into their routine. 
  • The diet does support short-term symptom reduction with the decrease in roughage and fiber after a liquid diet and keeps inflammation reduction a priority, however long-term gut healing strategies are not represented.
  • The diet was developed by Professor John Hunter when he was working with Crohn’s patients at Addenbrooke’s Hospital.
