A high-fiber diet benefits colon health by promoting regularity and preventing constipation. Dietary fiber adds bulk to the stool, facilitating smoother passage through the digestive tract. It can also support the growth of beneficial gut bacteria, enhancing overall gut health. Moreover, adequate fiber intake is associated with a lower risk of developing colorectal cancer. Foods like whole grains, legumes, fruits, and vegetables are excellent sources of fiber that contribute to a healthy colon.
