What Is Insoluble Fiber?

When it comes to fiber, there are two different types: soluble and insoluble. The soluble fiber found in oat bran, barley and some fruits and vegetables tends to absorb water and slow down digestion. The insoluble fiber in whole grains, nuts, seeds, fruits with skin and certain vegetables, on the other hand, can bulk up the stool and help it pass through your intestines faster.

But what grains, fruits and vegetables are high in insoluble fiber? The following insoluble fiber foods list will give you a starting point for what to eat.

Blackberries

When it comes to fruits with insoluble fiber, your best bet is to stick to fruits that you eat with the skin on. Fruits that need to be peeled, such as a banana, for example, may contain insoluble fiber, but not as much. A banana has insoluble fiber, but only about two to three grams of both kinds total. A better choice would be blackberries, which have more than six grams per cup!
