Malabsorption of modified food starch (acetylated distarch phosphate) in normal infants and in 8–24‐month‐old toddlers with non‐specific diarrhea, as influenced by sorbitol and fructose

Acetylated distarch phosphate (ADiSP) is a modified starch used in some baby foods. The bioavailability of ADiSP and a native (unmodified) starch was evaluated in 20 normal infants and 21 toddlers aged 8–24 mo with chronic non‐specific diarrhea. Formulae contained 8% native or 8% modified waxy maize starch. No infant or toddler consuming Formula N (native starch) had elevated peak breath hydrogen levels (20 ppm or greater), stools clinically positive for reducing substances (0.75% or greater) or loose stools. Fourteen infants received formula M (modified starch): 2 had elevated breath hydrogen, 1 had positive stools and another had loose stools. Of the 21 toddlers fed formula M, 2 had elevated breath hydrogen, but none had positive stools or loose stools. Formula NS (native starch with 2% sorbitol) had little effect on breath hydrogen in the infants but significantly increased it in the toddlers. Formula NS produced loose stools in 2 toddlers but no clinically positive stools in any infant or toddler. Formula MS (modified starch with 2% sorbitol) elevated breath hydrogen in 3 infants and 8 toddlers, and produced positive stools in 2 infants and 2 toddlers, and loose stools in 4 infants and 7 toddlers. Formula MSF (modified starch with 2% sorbitol and 5% fructose) elevated breath hydrogen in 7 infants and 10 toddlers, positive stools in 7 infants and 6 toddlers, and loose stools or diarrhea in 7 infants and 11 toddlers.
