FOS fructooligosaccharide, RG resistant glucan, HRG hydrogenated resistant glucan, AUC area under the curve. Five grams of test substances were ingested by healthy subjects. Data were expressed as median and interquartile in 10 healthy subjects. AUCs versus time for 14 h after ingestion of test substance were calculated based on the date shown in Fig. 5. The available energy of digestable fractions was calculated by content (%) × 4 kcal/g. Available energy was calculated based on our proposed method [4–6]
