Study: Fiber, Gut Bacteria and Colorectal Adenoma Risk

Bacteria

Evidence is strong that consuming high amounts of dietary fiber protects against colorectal cancer. Previous research has suggested that fiber may play a role in colon cancer prevention due to its interaction with trillions of bacteria in our gut.

Now, a study adds to that evidence by focusing on advanced colorectal adenoma, a non-cancerous tumor that has the potential to develop into cancer.

The study, published in The American Journal of Clinical Nutrition, suggests that a high-fiber diet promotes healthy gut bacteria and its byproducts.

Gut microbiota are the microorganisms that live in our digestive tracts – in our stomach, intestines, and colon. We have about 10 trillion human cells in our body, but we have way more – about 100 trillion – microorganisms residing in our gut. A growing body of research is showing that these microorganisms are important to our health – from training our immune system, to producing vitamins and fighting off harmful bacteria. Continue reading
