Abstract:

Colorectal cancer (CRC) is one of the most common cancer worldwide, especially in the western countries. Diet is one of the most important factors associated with CRC. Accumulating evidence suggests that diet could re-shape the human gut microbiota and contribute to the development of CRC, not only via the pro-tumorigenic activities of specific pathogens but also via the influence of metabolism and function of the whole microbial community, particularly its metabolites. Recent data have shown that short-chain fatty acids, especially butyrate, could suppress inflammation and anti-cancer, whereas other microbial metabolites, such as secondary bile acids, promote colorectal tumorigenesis. In this Review, we discuss the influence of diet on gut microbiota and its metabolites, the interaction between gut microbiota and CRC, and dietary strategies for CRC prevention. More mechanism studies are warranted to further investigate the interplay of gut microbiota with metabolome, immunity and host response.

Key words: Colorectal neoplasms, Diet, Gut microbiota, Metabolites
