Effect of dietary viscosity on energy intake by breast-fed and non-breast-fed children during and after acute diarrhea.

To determine the effect of dietary viscosity on energy consumption by young children, 56 Peruvian children 9-20 mo of age with acute diarrhea were randomly assigned to either a liquid or semisolid diet, with or without added amylase to reduce viscosity. Intakes of the study diet, breast milk, and other foods were measured for 2 consecutive d during and again after illness. Total 24-h energy intake (chi +/- SD) during diarrhea, 349.4 +/- 121.8 kJ/kg (83.6 +/- 29.1 kcal/kg) was 18% less than intake after recovery, 428.9 +/- 141.0 kJ/kg (102.6 +/- 33.7), P < 0.001. In the ANOVA breast-fed children consumed significantly less total energy (P = 0.008) and energy from the study diet (P = 0.02) than non-breast-fed children. Breast milk intake did not change with illness. There was no significant relationship between viscosity of the study diet and either total energy intake or intake of energy from the study diet. Energy intake by these children was primarily determined by health status and breast-feeding practice, not by dietary viscosity.
