Dietary Fiber

Also known as bulk and roughage, dietary fiber is an essential element in a person’s diet. fiber consists of plant cellulose and other indigestible materials in foods, along with pectins and gums. Unlike other food components, it can’t be digested by the human body. Such characteristic makes fiber make an important part of our diet.


The chewing fiber requires stimulates saliva flow, and bulk it adds in the stomach and intestines during digestion provides more time for absorption of nutrients. Diets with sufficient fiber produce softer, bulkier stools and help to promote bowel regularity and avoid constipation and other disorders. They may also aid in the prevention of some colon cancers and diseases of the colon and help lower blood cholesterol levels. High fiber foods are generally low in fat and cholesterol and rich in nutrients.

Fiber may come as water-insoluble or as water-soluble. Water-insoluble fiber promotes regularity and is an important aid in normal bowel function. It may help reduce the risk for colon cancer. Water-soluble fiber promotes a full feeling and helps control blood sugar levels by showing down the rate food is absorbed from the digestive tract. These fibers show promise in the treatment of obesity and diabetes. Water-soluble fiber has also been shown to help lower blood cholesterol levels.

  1. Thank you for the information. Now I know that too much fiber is also not good specially in the absorption of nutrients like iron and calcium. I think I need to lower down my fiber consumption as I can relate to this post.

  3. 1 Current licensing scheme drugs used in the United States means that buprenorphine, a patented drug may be legal, but it is much more difficult to establish new (for whites) as medicinal plants since no one can get a monopoly on sales thereof.
