Our gastrointestinal tract is important for our nutrient absorption and waste excretion and is home to most of our microbiota. Diseases affecting the gut, such as Crohn’s disease, lead to serious signs and complications. The biggest concern is knowledge gaps in why Crohn’s disease develops and treatment options. For this video, we got in touch with Dr. Sabah Haq,
a member of Dr. Waliul Khan’s lab that investigated the “Disruption of autophagy by increased serotonin alters gut microbiota and enhances susceptibility to experimental colitis and Crohn’s disease.” We also touch on another one of Dr. Khan’s papers, the impacts of Allura Red, an artificially added food colour in different snacks and treats, on the intestine
and the development of IBD (inflammatory bowel disease) and IBS (irritable bowel syndrome).
