Increasing dietary fiber lowers the risk of which type of cancer?

Increasing dietary fiber is widely recognized for its role in promoting digestive health, and one of the significant benefits associated with a high-fiber diet is the reduction in the risk of colon cancer. Dietary fiber aids in the regularity and health of bowel movements, which can help to dilute potential carcinogens in the colon and potentially reduce the time they are in contact with the intestinal lining. Moreover, fiber promotes the growth of beneficial gut bacteria, which can contribute to a healthier gut environment and reduced inflammation, both of which are associated with lower cancer risk.

The correlation between high fiber intake and lower rates of colon cancer has been supported by numerous studies, highlighting not only the protective effect of fiber on the colon but also its ability to improve overall gut health. This is why increasing dietary fiber is specifically linked to a reduced risk of colon cancer compared to the other types of cancers listed in the options.
