Why is fiber important for health?

Fiber is one of the most essential nutrients in our diet, playing a crucial role in maintaining our overall health and well-being.

What is Fiber?

Fiber, also known as dietary fiber, is the indigestible part of plant-based foods. It is found in fruits, vegetables, whole grains, and legumes. There are two types of fiber: soluble and insoluble. Soluble fiber dissolves in water and forms a gel-like substance, while insoluble fiber does not dissolve in water and helps add bulk to stool. Both types of fiber are essential for maintaining a healthy digestive system.
