By Dr Pranab Gyawali, Consultant Gastroenterologist
Introduction:
I’m Dr. Pranab, a consultant gastroenterologist in Dubai with over 25 years of experience treating Crohn’s disease, ulcerative colitis, and other IBD conditions. Diet is one of the most common questions my patients ask about Crohn’s disease, and rightly so. This year at Digestive Disease Week (DDW 2025), two major studies were presented that explored how plant-based diets could influence Crohn’s disease and IBD management.
In this vlog, I’ll break down what we learned, how the research is shifting from animal models to human studies, and what this could mean for patients living with IBD.
Why Diet Matters in Crohn’s Disease
For many years, diet was considered a secondary factor in Crohn’s disease management. However, more recent research highlights how dietary patterns can influence inflammation, gut microbiome diversity, and overall IBD outcomes. Plant-based diets, in particular, are being studied for their anti-inflammatory and microbiome-supportive properties.
From Mice to Humans – The Research Journey
Earlier studies in mouse models showed that plant-based, low-calorie diets improved IBD-related gut damage. These results generated strong interest in moving to human trials.
At DDW 2025, the University of Alberta presented one of the first large-scale studies on plant-based diets in Crohn’s patients. They revealed promising results, demonstrating dietary impacts on inflammation markers and clinical outcomes.
Following this, Stanford University shared their findings, adding weight to the idea that dietary intervention could become an important complementary approach in IBD care.
What This Means for Patients in Dubai
As a practicing gastroenterologist in Dubai, I often see patients searching for dietary answers to manage Crohn’s disease and ulcerative colitis. These updates confirm what many patients already feel intuitively — diet matters. While medication remains the cornerstone of treatment, plant-based dietary strategies may offer additional benefits in reducing flares and improving quality of life.
My Takeaway as a Gastroenterologist
These findings are exciting, but it’s important to be cautious. Diet is highly individual in IBD, and what works for one patient may not work for another. My advice remains the same: always discuss dietary changes with your gastroenterologist and a qualified dietitian before making adjustments.
Conclusion:
This year’s DDW conference has given us some of the clearest evidence yet about the role of diet in Crohn’s disease. From mice to humans, the research is progressing — and that’s good news for patients everywhere.

FAQ
Q1: Can a plant-based diet cure Crohn’s disease?
A: No, diet alone cannot cure Crohn’s disease. However, recent research suggests that plant-based diets may help reduce inflammation and improve symptoms in some patients.
Q2: Should I stop my Crohn’s medications if I try a plant-based diet?
A: Absolutely not. Medications remain essential in managing Crohn’s. Dietary changes should be complementary, not replacements.
Q3: Is a plant-based diet safe for all IBD patients?
A: Not always. Patients with strictures, severe malnutrition, or active flares may need modifications. Always consult your gastroenterologist and dietitian first.
Q4: What foods are considered part of a plant-based diet in Crohn’s?
A: Fruits, vegetables, legumes, grains, nuts, and seeds. However, individual tolerances vary — some patients may need adjustments.
