What crucial element for gut motility is mostly removed during celery juicing?

Insoluble dietary fiber

When celery is processed into juice, the extraction method separates the liquid components from the solid structural material, which is primarily insoluble dietary fiber. This fiber is critically important for gastrointestinal well-being because it adds necessary bulk to stool, which in turn promotes regular bowel movements and actively prevents constipation. Because juicing strips away this insoluble component, the resulting liquid, while rich in water and certain soluble nutrients, lacks the mechanical benefit required to support gut motility and overall digestive regularity that consuming the whole stalk provides. Nutrition experts emphasize this distinction, advocating for the whole vegetable when the goal is optimizing fiber intake for the digestive system.
