Colorectal cancer (CRC) is a worldwide health issue. It causes illness and death in millions of people each year. A positive correlation has been observed between the intake of dietary fat and the development of CRC. The composition of gut microbiota exhibits a significant correlation with pathophysiologic processes in intestine. Clinical treatment remains inadequate due to the complex pathogenic mechanisms of CRC triggered by a high-fat diet (HFD). Naringenin, a flavonoid from grapefruit, has anti-cancer activity. Our findings suggest that naringenin enhances gut microbiota diversity by increasing the abundance of beneficial bacterial species while reducing opportunistic pathogenic bacteria. The fecal microbiota transplantation assay (FMT) demonstrated that the antiHFD-CRC activity of naringenin depended on the gut microbiota. Furthermore, naringenin antagonized the IL-6/STAT3 pathway. These results suggest that naringenin may be a potential treatment for HFD-CRC.
