Amioca cornstarch (100% amylopectin) and Hi-Maize 260 were used for control and resistant starch (RS) diets, respectively; both starches were provided by National Chemical and Starch Company (Bridgewater, NJ). Metabolizable energy values were 3.5 kcal/g for Amioca cornstarch (data provided by National Starch and Chemical) and 2.8 kcal/g for Hi-Maize 260 (unpublished data based on bomb calorimetry). RS content in the diet was calculated on the basis of the amount of Hi-Maize (56% RS) used.
