Soluble fiber and insoluble fiber are two kinds of fiber in our diet. Dietary fiber is the part of plant foods we eat and cannot digest. Most fiber-rich foods contain both soluble and insoluble fiber.

Some fiber dissolves in water. This is soluble fiber. Fiber that does not dissolve in water is called insoluble fiber. 

Soluble fiber is often viscous. Viscous means it becomes a thick gel when mixed with water. Foods rich in soluble fiber are fruits, vegetables, beans and oats.

Insoluble fiber is often non-fermentable. This means it passes through your body unchanged. Some foods rich in insoluble fiber are fruits, vegetables, beans, whole grains, nuts and seeds.

Foods rich in fiber usually have both types of fiber. Some foods have more soluble foods. Some foods have more insoluble fiber. Fiber-rich foods include fruits, vegetables, beans, whole grains, nuts and seeds.

Soluble fiber and insoluble fiber are two kinds of fiber in our diet. Their ability to dissolve in water differs. Eating fiber-rich foods is part of a healthy diet.
