Function: Fiber is an important element of the diet as it promotes a healthy digestive system, and helps prevent hemorrhoids and diverticulosis (small pouches that bulge outward in the large intestine).  Fiber also helps in preventing Colon Cancer, as well as lowering cholesterol and blood sugar.

Fiber can be divided into two forms, Insoluble Fiber and Soluble Fiber.  Neither one of these forms are digested or absorbed into the blood stream.  While Soluble Fiber forms a gel when mixed with liquid, Insoluble Fiber does not.

Insoluble Fiber moves bulk through the intestines and controls the acidity in the intestines.  It prevents constipation, removes toxic waste from the colon in less time, helps prevent Colon Cancer, and prevents microbes from producing cancerous substances.

Soluble fiber binds to fatty acids and prolongs digestion time of stomach contents.  This helps to regulate blood sugar and manage diabetes.  Soluble Fiber also reduces the risk of heart disease by lowering not just the overall cholesterol, but the Bad Cholesterol (LDL) as well.


Insoluble Fiber : Dark leafy vegetables, beans, fruit skins and root vegetable skins, whole-wheat products, corn bran, seeds and nuts.

Soluble Fiber : Oats and Oat Bran, dried beans and peas, nuts, barley, flax seed, fruits such as apples and oranges, and vegetables such as carrots.
