Fibre IBD Study

Purpose of Fibre IBD study
We are exploring how different types of dietary fibre affect gut health in people with ulcerative colitis (UC).
We are also looking for non-UC participants to take part as controls.
Because some fibres may be harder to digest for individuals with UC, our goal is to understand whether personalized fibre and nutrition recommendations can:
- Improve the microbes in the gut
- Support better nutrition
- Help reduce inflammation
This research will help us design more effective, individualized dietary strategies for people living with UC.
What is Involved
If you choose to participate, you will follow a personalized fibre-rich diet for 4 weeks, with guidance and support from a registered dietitian throughout the process.
As part of the diet, you will also be asked to avoid certain foods, including red meat, processed meats, processed dairy, and alcohol.
Throughout the 4-week study period, we will monitor how the diet affects your physical and mental well-being. This includes:
- Completing online questionnaires and 3-day food diary
- Providing stool samples at the beginning and end of the study
- A blood draw at the end of the study
Additionally, during your previously scheduled colonoscopy, we will collect a small number of additional samples, such as biopsies, blood, and a mucosal wash.
Who can participate
You may be able to participate in this study if you are:
- An adult aged 19 to 69
- Undergoing a colonoscopy
- On stable treatment for at least one month [only for UC patients]
- Clinically in remission or with mild to moderate disease [only for UC patients]
You will not be eligible to participate in this study if you:
- Used antibiotics, pro-/pre-biotics supplements or had an enteric infection in the last 30 days
- Had an abdominal surgery (excluding C-section)
- Currently taking systemic steroids
- Pregnant
