Composition of plant-based diets and the incidence and prognosis of inflammatory bowel disease: a multinational retrospective cohort study.

ABSTRACT:

Background

Many currently proposed diets for inflammatory bowel disease (IBD) focus on increasing plant-based foods, although a vegetarian diet can still contain products such as emulsifiers and refined grains that are believed to negatively impact IBD incidence and progression. To better inform dietary management in IBD, we investigated the association between plant-based diets and the incidence and complications of IBD.
