“Colorectal cancer (CRC) is one of the leading causes of mortality for cancer in industrialized countries. The link between diet and CRC is well-known, and presumably CRC is the type of cancer which is most influenced by dietary habits. In Western countries, an inadequate dietary intake of fibers is endemic, and this could be a driving factor in the increase of CRC incidence.”
Fiber prevents colon cancer primarily by increasing stool bulk and speeding up transit time, which reduces the contact between harmful carcinogens and the colon lining. It also acts as food for beneficial gut bacteria, fermenting into short-chain fatty acids like butyrate that reduce inflammation and promote cancer cell death.
