While fiber does help to promote healthy digestion and regular bowel movements, it may not necessarily clear away partially digested food that is stuck along the walls of the digestive tract. Fiber can help to bulk up the stool and promote regular bowel movements, which can help to prevent constipation and keep the digestive system functioning properly. However, if there is food that is stuck or not being properly digested in the digestive tract, it may require other interventions such as increased hydration, enzyme supplements, or medical evaluation by a healthcare provider.
