Abstract
En 中文
Diet is increasingly recognized not as a passive exposure but as a dynamic determinant of inflammatory bowel disease (IBD) pathogenesis, progression, and treatment response. This review article redefines diet as a multidimensional modifier acting through complex interactions with genetics, microbiota, intestinal barrier function, and environmental exposures. Beyond nutrient composition, we highlight how age, sex, habitual diet, cooking methods, contaminants, and lifestyle collectively shape disease trajectories. We also identify key research priorities: incorporation of long-term, mechanistically anchored trials; development of digital, biomarker-informed dietary assessment tools; and integration of polygenic, microbial, and metabolic data to inform individualized therapy. Emerging evidence also calls for culturally tailored and patient-centered frameworks that ensure real-world adherence and equity in dietary interventions. Reframing diet as a biological, behavioral, and environmental nexus shifts it from the periphery to the forefront of IBD care, transforming it from a confounder in research to a therapeutic frontier in clinical practice.
