They discovered that a toxin produced by the bacterium—known as BFT—must first attach to a protein on the surface of colon cells called claudin-4. "For a long time, we've known that certain factors like genetics and diet play a role, but this growing body of research, including the new study, emphasizes that the composition of our gut microbiome is a critical factor in colon health," Ligresti told Newsweek. "The presence of the non-toxin-producing strain is not a cause for concern." Maintaining a healthy lifestyle, including eating a fiber-rich diet with plenty of fruits, vegetables and whole grains, limiting red and processed meats, exercising regularly and maintaining a healthy weight are practical steps people can take to support colon health and reduce their overall risk of colorectal cancer, Ligresti said.
