Abstract: Inflammatory bowel disease (IBD) is a group of intestinal chronic inflammatory disease characterized by intestinal inflammatory cell infiltration and intestinal mucosa damaged, including Ulcerative Colitis and Crohn's disease. Epidemiologic findings indicated that high fat intake increased the risk of IBD, the incidence of IBD was assosiated with the increase in the intake of animal protein., and dietary fiber intake was negatively correlated with the incidence of IBD. The pathogenesis of IBD is complex, including genetic factors and environmental factors, of which diet is one of the most important environmental factors. Currently, dietary nutrition intervention is an effective strategy for prevention and control of IBD. In this review we summarized the studies on the effects of dietary fat, protein and carbohydrate on the pathogenesis of IBD in recent years, and analyzed the dietary intervention strategies of IBD from the perspective of dietary nutrients.
