Insoluble fiber Updated on: July 26th, 2019

Insoluble fiber is indigestible fiber. The body doesn't break it down so the form it goes in is the form it goes out! Known as "roughage", examples of insoluble fiber include whole wheat, potatoes, and the skin, stalks, and seeds of many fruits and vegetables.

why we feed

Insoluble fiber adds bulk to stool and helps stool move faster through the intestines, which helps ease constipation. It is not recommended for treating diarrhea alone as it can make it worse.

how to feed

There are many whole food sources of insoluble fiber so feeding recommendations will also depend on the food.

Additional info

Since insoluble fiber remains indigested, it can block mineral absorption and drug interaction if fed too much.
