What is peristalsis and how does it relate to fiber?

Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. Fiber plays a crucial role in this process by adding bulk to the stool, which stimulates the walls of the intestines to contract more effectively. This enhanced movement helps prevent constipation and promotes regular bowel movements, making fiber an essential component of a healthy diet for optimal digestive health.
