Effect of Dietary Fiber and Starch on Fecal Composition in Preschool Children Consuming Maize, Amaranth, or Cassava Flours

Metabolic balance studies were carried out in young children fed diets based on maize, amaranth, or cassava flours and in corresponding casein controls. Dietary fiber intakes were 22.2, 20.5, and 9.0 g/day for the maize, amaranth, and cassava groups, respectively. Fecal energy losses at least doubled in all test diets when compared with the corresponding controls and could generally be accounted for by recovered fiber in the feces. Fecal starch was also a significant contributor to fecal energy in the cassava group. All cassava fiber was recovered in the feces, whereas only 48.4 and 16.3% were recovered from ingested maize and amaranth. 2,6-Diaminopimelic acid (DAPA), an indicator of bacterial mass, was highest in the cassava group. Expired breath hydrogen was highest for those consuming maize or cassava. Resistant starch may have been responsible for the high DAPA and breath hydrogen values in the cassava group.
