Abstract:
The incidence of colorectal cancer( CRC)increases rapidly in recent years. The role of dietary structure in CRC pathogenesis has caught much attention. This review summarizes the relationship between dietary fiber intake and risk of CRC. Accumulating evidence reveals that up to 90% CRC can be prevented by improvement of dietary structure,and high fiber intake(10-35 g/d)decreases 10%-17% of risk of CRC. All kinds of dietary fiber have preventive effect. So far, dietary fiber intake in Chinese people does not reach the recommended level. Optimization of dietary structure,increase intake of whole grains,vegetable and fruit,addition of fiber to daily food are effective approaches for prevention of CRC.
