Personalized B-fructan Diet in Inflammatory Bowel Disease Patients
November 29, 2023 updated by: University of Manitoba
The Fibre Study: RCT of Personalized Fibre Diet in IBD
This study aims to examine patient tolerability of personalized dietary fibre consumption recommendations (high-pectin diet versus high-B-fructan diet based on personalized responses), provided by an IBD dietician, based on our novel translational research findings.

Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
Eligibility Criteria
Ages Eligible for Study
6 years to 39 years (Child, Adult)
Accepts Healthy Volunteers
Yes
Description
Inclusion Criteria:
- Children (age 6-17) or young adults (age 18-39).
- Known or suspected UC or IBDU [there will be 2 control group: non-IBD (undergoing colonoscopy but found not to have IBD; and healthy (no GI symptoms, so not required to have colonoscopy; could be family members)]
- For UC: Remission-mild-moderate disease: Mayo score <10
- Clinical indication for sedated colonoscopy
- Disease location: E2-E4
- Stable treatment (not on steroids; biologics or immunomodulator not changed in last month)
- High likelihood that patients will be able to collect all samples and provide all data
Exclusion Criteria:
- Use of antibiotics for a week or more over the last 3 months
- Use of probiotics or prebiotics at pharmacological doses (adding fibre sources to food or probiotics in yogurt, for example, are allowed)
- History of abdominal surgery, including appendectomy
- Documented enteric infection during the 3 months prior to endoscopy
- Presence of non-IBD bowel conditions (e.g., celiac), anatomical or mucosal abnormalities, motility disorder
- Presence of a systemic disease requiring treatment (cancer, ischemic heart disease, kidney failure, etc)
- Proctitis (E1)
- Systemic steroids (above 10 mg/day of Prednisone)
- Topical therapy within 1 week of endoscopy
- Recent change in IBD treatment (started biologics or IM over the last month)
- Pregnancy or planning to become pregnant during the study
- Inability to understand or sign the consent

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Placebo Comparator: Randomized pectin diet
|
UC and healthy control participants randomized to receive recommendations provided by a dietician increasing consumption of foods high in pectin
|
Placebo Comparator: Randomized B-fructan diet
|
UC and healthy control participants randomized to receive recommendations provided by a dietician increasing consumption of foods high in B-fructan
|
Experimental: Personalized pectin diet
|
UC and healthy control participants to receive recommendations provided by a dietician increasing consumption of foods high in pectin based on personal host (biopsy) and microbe (stool) response at baseline
|
Experimental: Personalized B-fructan diet
|
UC and healthy control participants to receive recommendations provided by a dietician increasing consumption of foods high in B-fructan based on personal host (biopsy) and microbe (stool) response at baseline

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Diet tolerability
Time Frame: 4 weeks
|
Percentage of patients able to tolerate a personalized fiber diet provided by a dietitian will be evaluated at week 4 by measure of patient symptom score (PROMIS questionnaire) and willingness to continue adherence to diet advice provided.
|
4 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Inflammatory response to diet
Time Frame: 1 week, 4 weeks, 8 weeks, 12 weeks
|
Host inflammatory response to personalized dietary fibre recommendations provided by dietitian will be determined by examining changes in markers of inflammation in blood and stool
|
1 week, 4 weeks, 8 weeks, 12 weeks
|
Microbiota changes in response to diet
Time Frame: 1 week, 4 weeks, 8 weeks, 12 weeks
|
Host microbiota response to personalized dietary fibre recommendations provided by dietitian will be determined by examining changes in microbe abundance, diversity and functions by shotgun metagenomics in stool
|
1 week, 4 weeks, 8 weeks, 12 weeks
