A recent study highlights the important role of gut bacteria in boosting the protective effects of dietary fiber against colorectal cancer.
The gut microbiome is a community of trillions of microorganisms living in the digestive tract and it plays a key role in processing food, supporting immunity, and maintaining overall gut health.
When dietary fiber is fermented by these bacteria, it produces short-chain fatty acids (SCFAs) such as butyrate and propionate. These compounds help regulate gene expression, reduce inflammation, and promote a healthy intestinal environment, all of which may lower cancer risk.
The study emphasises that a fiber-rich diet supports beneficial gut bacteria and overall colon health. While the findings are promising, more research is needed to fully understand the mechanisms and confirm these effects in humans.
