Cure8 news brief
Dietary patterns may differ between people who develop Crohn’s disease or ulcerative colitis and their healthy relatives; understanding these associations could help guide prevention research and personalized nutrition counseling.
Adults with Crohn’s disease or ulcerative colitis, clinicians and dietitians working with IBD patients, and researchers studying diet–IBD links.
This peer-reviewed cohort study compared reported pre-illness dietary intakes of people with Crohn’s disease (CD) and ulcerative colitis (UC) to those of their paired healthy relatives and to healthy non-relatives.
The authors identified different dietary patterns associated with CD versus UC when using relatives as controls: for CD, lower intakes of vitamin C, dietary fiber, calcium, vegetables, milk/dairy and certain fatty acids were highlighted; for UC, lower intakes of phosphorus, DPA (docosapentaenoic acid), vitamins B2 and B12, and choline — and a higher α-carotene intake — were reported.
The paper used statistical methods including LASSO regression to prioritize the most relevant dietary features. If you read the full article, you’ll find the analyses compare patients to both family-member controls and unrelated healthy controls, and the authors argue that paired relatives help control for shared genetics and environment.
The text notes this is based on dietary recall and that the full article and datasets require institutional access or contact with the corresponding author.
Observational study using dietary recall and paired relatives as controls — shows associations, not proof of cause-and-effect. Full methods and data require access to the journal article.
