BACKGROUND
Addition of a small amount of amylase rich flour (ARF) to a thick porridge instantly liquefy the porridge and increase the energy intake even by sick children. The present study examined the absorption of macronutrients and calorie from an energy dense diet liquefied with ARF in children aged 6-11 months with acute watery diarrhea.
METHODS
After adequately hydrated with oral rehydration fluid over a period of 24 hours, children were randomly assigned to receive either an ARF treated liquefied porridge (test diet) or a porridge diluted with water (control diet). A 72-hour metabolic balance was performed to determine the absorption of carbohydrate, fat, protein, and calorie.
RESULTS
Thirteen infants received the test diet, and 15 infants received the control diet. The intake of protein (g/kg/d), carbohydrate (g/kg.d), fat (g/kg.d) and calorie (kJ/kg.d) were 1.97, 20.6, 4.3 and 548 respectively in the test group and those in the control group were 1.12, 13.3, 2.8 and 356. The stool loss of protein, carbohydrate and fat were comparable in the two groups. The absorption coefficient (%) of carbohydrate, fat and energy were 69.6, 61.3 and 65.4 in the test group and were 73.2, 58.6 and 66.7 in the control group. The coefficient of absorption of protein was significantly higher in the test group (37.7% vs. 21.7%). The mean (95% CI) nitrogen balance (g/kg.d) in the test and control groups were 0.064 (0.026, 0.102) and -0.029 (-0.055, 0.003) respectively.
CONCLUSIONS
The results suggest that energy dense diet liquefied with ARF was well absorbed in children with acute diarrhea and there was a positive nitrogen balance that may have a positive impact in preventing weight loss during acute illness.
