What Provides bulk to food to keep it moving through the gut?

Dietary fiber provides bulk to food, aiding in the movement of contents through the gut. It adds volume to the stool and helps regulate bowel movements by promoting peristalsis, the wave-like muscle contractions that move food through the digestive tract. Sources of dietary fiber include fruits, vegetables, whole grains, and legumes. Adequate fiber intake is essential for maintaining digestive health.
