Inflammatory bowel disease (IBD) — an umbrella term for conditions including Crohn’s disease and ulcerative colitis — affects millions of people worldwide, sometimes severely affecting their quality of life. How is the gut microbiome of a person with IBD different, and can we use diet to change it and help with disease management? To answer these and other questions, we are in conversation with Dr. Marcel de Zoete, associate professor in the Department of Medical Microbiology at UMC Utrecht in The Netherlands, who has studied the gut microbiome in IBD. Also joining us is Zosia Krajewska, who lives with IBD after receiving a diagnosis at age 14.
