Dietary fiber or Dietary fibre or sometimes roughage is the indigestible portion of plant foods having two main components:
·
Soluble (prebiotic, viscous) fiber that is readily fermented in the colon into gases and physiologically active byproducts, and
·
Insoluble fiber that is metabolically inert, absorbing water throughout the digestive tract and easing transit.
It acts by changing the nature of the contents of the gastrointestinal tract, and by changing how other nutrients and chemicals are absorbed. Soluble fiber absorbs water to become a gelatinous, viscous substance and is fermented by bacteria in the digestive tract. Insoluble fiber has bulking action and is not fermented, although a major dietary insoluble fiber source, lignin, may alter the fate and metabolism of soluble fibers.
