What Are High-Fiber Foods and Why Do They Matter?
The Science of Dietary Fiber
Dietary fiber is a part of plant foods that your body can’t digest. It includes two types: soluble fiber, which dissolves in water, and insoluble fiber, which does not. Both types help keep your digestive system healthy.

High-fiber foods support regular bowel movements, help lower cholesterol levels, stabilize blood sugar, and can help you feel full longer. Fiber is also linked to lower risks of some chronic diseases.
