This research aims to explore the biological mechanisms linking ultra-processed food consumption to inflammatory bowel disease via specific metabolites.
Constructed a metabolic signature of ultra-processed food using data from the UK Biobank and validated in additional cohorts.
Applied elastic net regression and Cox regression analyses to evaluate the association between metabolites and disease risk.
Used weighted gene co-expression network analysis to identify clusters of metabolites and their roles in inflammation.
Conducted Mendelian randomization to assess causality and the influence of genetic variants on the metabolite-disease relationship.
Developed a metabolic signature comprising 73 metabolites linked to an increased risk of inflammatory bowel disease.
Identified docosahexaenoic acid (DHA) as a key metabolite inversely associated with Crohn’s disease risk.
Found specific genetic variants in the FADS1 gene that interact with dietary DHA levels affecting disease susceptibility.
