Overview

Insoluble fiber is a type of dietary fiber. Unlike soluble fiber, it does not dissolve in water and is left intact as food moves through the gastrointestinal tract. This type of fiber helps to add bulk to the stool, which can help to prevent constipation and irregular stools.

Sources of Insoluble Fiber

Insoluble fiber is found in many types of foods. Some of the best sources include whole grains, such as brown rice and whole wheat bread. It is also found in the skin of many fruits and vegetables, as well as in nuts, seeds, and legumes.

Health Benefits

There are many health benefits associated with consuming a diet high in insoluble fiber. It can help to prevent constipation by adding bulk to the diet and promoting regular bowel movements. Some research also suggests that insoluble fiber may help to reduce the risk of developing certain types of cancer, such as colon cancer.

Dietary Recommendations

The Dietary Guidelines for Americans recommends that adults consume between 25 and 38 grams of dietary fiber per day, depending on age and sex. This should come from a variety of sources, including both soluble and insoluble fiber.
