36 Facts About Dietary Fiber

What is Dietary Fiber?

Dietary fiber, also known as roughage, is a type of carbohydrate that the body can't digest. Unlike other carbs, fiber passes through the digestive system relatively intact. It plays a crucial role in maintaining overall health.

1. Dietary fiber helps regulate the body's use of sugars, keeping hunger and blood sugar in check.
2. There are two types of fiber: soluble and insoluble. Soluble fiber dissolves in water, forming a gel-like substance, while insoluble fiber adds bulk to the stool.
3. Soluble fiber can help lower glucose levels and blood cholesterol.
4. Insoluble fiber aids in moving material through the digestive system and increases stool bulk.
