Patients with Inflammatory Bowel Disease (IBD), Crohn's Diseases (CD) and Ulcerative Colitis (UC), pay special attention to what they eat. The best way to maintain adequate nutrition is to work with your healthcare team, make healthy food choices, and avoid foods that make your symptoms worse.
One of the recent studies*, focused on the impacts of Mediterranean diet (Md) on IBD, CD, and UC. They showed a "significant reduction of malnutrition-related parameters" after short-term dietary intervention and a "spontaneous improvement of disease activity and inflammatory markers".
