Gastrointestinal Health Benefits

The digestive system greatly benefits from the inclusion of vegetables in the diet. The fiber in vegetables aids in digestion, preventing constipation and promoting regular bowel movements.

  • Diverticulosis Prevention: The bulking and softening action of insoluble fiber can decrease pressure inside the intestinal tract, potentially preventing diverticulosis.
