Abstract

VALENZUELA B, Andrea  and  MAIZ G, Alberto. ROLE OF DIETARY FIBER IN ENTERAL NUTRITION. Rev. chil. nutr. [online]. 2006, vol.33, suppl.2, pp.342-311. ISSN 0717-7518.  http://dx.doi.org/10.4067/S0717-75182006000400002.

Dietary fiber is constituted by a heterogeneous group of substances of vegetal origin that are resistant to digestion and absorption in the upper gastrointestinal tract, but that are partially or totally digested in the colon. The insoluble fiber aids to maintain a normal intestinal transit and the soluble one has beneficial effects on the micro flora of the colon where it is fermented generating short chain fatty acids (SCFA). The SCFA are the preferential substrate for the intestinal cells. Despite the knowledge of the beneficial effects of the fiber the formulas of enteral nutrition (EN) that are commonly indicated do not contain it. Recently, soluble fiber fructooligosaccharides (FOS) has been incorporated into some of these formulas, being useful for the handling of diarrhea on patients receiving EN treatment. Moreover, these formulas seem to be useful for the treatment of patients with inflammatory intestinal diseases or short-bowel syndrome

Keywords : enteral nutrition (EN); dietetic fiber, fructooligosaccharides (FOS); short chain fatty acids (SCFA).
