Why is the whole celery stalk considered superior to celery juice for supporting gut health directly?

It retains beneficial insoluble fiber necessary for gut motility

The key advantage of consuming celery in its whole stalk form, as opposed to drinking the extracted juice, lies entirely in the retention of dietary fiber, particularly the insoluble type. Insoluble fiber is the structural component that is crucial for the physical regulation of the digestive process. It provides necessary bulk, which stimulates peristalsis—the muscular contractions that move food through the intestines—thereby supporting gut motility and preventing stagnation that leads to constipation. Juicing isolates the liquid concentrate, removing this essential physical structure. Consequently, while juice offers hydration and soluble nutrients quickly, the whole stalk is the superior choice when the specific health goal is maintaining robust and regular digestive function.
