Digestive Health and Fiber Content

Watermelon’s high water content (91%) promotes hydration and supports digestive health. It can help prevent constipation and maintain regular bowel movements.

The fruit contains a small amount of dietary fiber, approximately 0.4 grams per 100 grams. While not a significant source, this fiber contributes to overall digestive health by:

  1. Promoting regular bowel movements
  2. Supporting beneficial gut bacteria
  3. Helping to maintain a healthy weight

Watermelon’s natural sugars can cause gas or bloating in some individuals, especially when consumed in large quantities. Eating watermelon in moderation and chewing thoroughly can help minimize these effects.
