Diet and the Colonic Environment: Measuring the Response of Human Colonic Bacteria to Changes in the Host’s Diet

  • Abigail A. Salyers

Abstract

As dietary fiber passes through the human colon, a substantial portion of it is digested by the resident bacteria (Van Soest, 1978; Ehle et al., 1982). Clearly, this digestion by bacteria alters the structure of the fiber itself. It is also possible that dietary fiber affects the bacteria in turn by changing both the metabolic activities and the species composition of the colonic microflora. The question of how and to what extent fiber in the diet affects the colonic microflora is an important one because the metabolic activities of these bacteria largely determine the physicochemical environment of the colon.
