Effect of amounts consumed on the digestion of cassava by young children.
To determine whether increasing proportions of cassava could be consumed and satisfactorily digested, eight recovering malnourished children (20-38 mo old) received 25, 50 and 75% of their diet energy as freeze-dried cassava flour during 9-d periods, with intervening casein control diets. Enough casein was added to all cassava diets to bring protein energy to 8% of the total. When compared to the control diet, the 25% diet had no significant effect on consumption time or measures of protein and energy digestion. With the 50% diet, fecal wet and dry weights were moderately higher than with the 25% diet (196 +/- 44 and 24 +/- 4 vs. 121 +/- 36 and 16 +/- 3 g/d, respectively), as were fecal energy (89 +/- 16 vs. 63 +/- 16 kcal/d) and calculated carbohydrate (11 +/- 2 vs. 5 +/- 1 g/d); apparent nitrogen absorption (mostly from casein) was slightly lower (79 +/- 5 vs. 83 +/- 6%) and consumption time slightly higher (5-25, median 10, vs. 4-18, median 6 min/feeding). When energy from cassava was increased to 75%, fecal weights (240 +/- 49 and 31 +/- 5 g/d), energy (124 +/- 27 kcal/d) and carbohydrate (16 +/- 4 g/d) were all higher than when cassava provided 50 or 25% of energy. Consumption required 8-34, median 17 min/feeding and apparent nitrogen absorption was 76 +/- 6% of intake.(ABSTRACT TRUNCATED AT 250 WORDS)
