What are ultra-processed foods?
Recent interest has focused on the role of ultra-processed foods (UPFs) in IBD. UPFs are foods whose constituent ingredients are of exclusive industrial availability [1]. Across Europe, 30%–60% of energy intake in the diet is from UPFs [2, 3].
What is the research on ultra-processed foods and IBD?
Higher intakes of UPFs (especially through consumption of soft drinks, processed meat, salty snacks and refined sweetened foods) are associated with a greater risk of developing IBD [4], although a meta-analysis demonstrated an increased risk for Crohn’s Disease (CD) but not Ulcerative Colitis (UC) [5]. Once a person has been diagnosed with IBD, higher intakes of UPFs are associated with a greater incidence of IBD-related surgery [6] and a higher number of episodes of active disease in UC [7].
