Abstract: Inflammatory bowel disease (IBD) is a group of chronic inflammatory intestinal disorders characterized by intestinal inflammatory cell infiltration and intestinal mucosal damage, including ulcerative colitis and Crohn’s disease. Epidemiological findings indicated that high fat intake increased the risk of developing IBD, the incidence of IBD was associated with increased intake of animal proteins, 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 the prevention and control of IBD. In this review we summarize recent studies on the effects of dietary fat, proteins and carbohydrates on the pathogenesis of IBD, and analyze dietary intervention strategies against IBD from the perspective of dietary nutrients.

Key words: dietary nutrients, inflammatory bowel disease, pathogenesis, dietary intervention
