Insoluble fiber

Many scientists have found it useful lot distinguish two of dietary fiber: soluble and insoluble. It is important because the two types of fiber have different effects on the human body.

Plant cell walls that do not dissolve in water are collectively referred to as insoluble dietary fiber.

These components are cellulose, hemicellulose and lignin. Cellulose is a non-digestible form of fiber which is found in the outer portions of vegetable and fruits. It is usually found in their crunchy, woody, stems, stalks and peels.

This kind of fiber is a natural laxative. It absorbs, water helps the person feel full after eating and stimulates intestine walls to contract and relax.

Foods high in insoluble fiber are wheat, whole grains, brown rice, cereals, seeds, and the skin of many fruits and vegetables.

Insoluble fiber is found in large amounts in wheat bran and corn bran. Cold bran cereals have more insoluble fiber that hot cereals.

Bran contains cellulose and other cell wall materials and slows the rise in blood sugar after a meal. Bran can protect against heart disease in middle aged men.

Insoluble fiber is incredibly absorbent. It can soak up many times its weight in water as it passes through the intestines.

The benefits of Insoluble fiber

Fibers can be breakdown according to whether they insoluble or water soluble. Insoluble fiber includes cellulose and lignin.

Insoluble fiber appeases the appetite, reduced bacterial toxins, speeds the elimination of waste, absorbs toxins, softens stools, and improves bowel disorders.

Insoluble fiber holds water in the colon, thereby increasing bulk and stimulating the muscles of the digestive tract so that they retain their health and tone.

The toned muscles can more easily move waste products though the colon for excretion.

When consumed with sufficient amount of fluid, insoluble fiber can help prevent and alleviate constipation. 

However, consuming immoderate amounts of insoluble fiber may decrease the absorption of certain minerals, such as irons, calcium, and magnesium.

Foods high in insoluble fiber are wheat, whole grains, brown rice, cereals, seeds, and the skin of many fruits and vegetables.

Bran is a common and inexpensive source of insoluble fiber. Cold bran cereals have more insoluble fiber that hot cereals.
