Abstract

OBJECTIVE

To establish a method to determine food oral-colon transit time (OCTT).

METHODS

OCTT was determined for five groups of food rich in carbohydrate in 13 healthy adults with breath hydrogen test (BHT) using lactulose as control.

RESULTS

OCTT was 90.0 +/- 50.6 min, 237 +/- 64.9 min, 341.3 +/- 77.9 min and 352.5 +/- 59.5 min, respectively for lactulose syrup, sweet potato, steamed bun and corn flour, and OCTT could not identified for rice and rice with ground meat due to hydrogen production only in few study subjects or no rising in hydrogen value. OCTT inversely correlated with peak hydrogen value (r = -0.6625) and correlated with the time of peak hydrogen value and food absorption rate (r = 0.7668 and 0.8790).

CONCLUSION

BHT is a simple, reliable, non-invasive and feasible method to determine food OCTT.

摘要

目的

建立一种测定食物口腔-结肠转运时间（OCTT）的方法。

方法

采用呼气氢试验（BHT），以乳果糖为对照，对13名健康成年人的五组富含碳水化合物的食物进行OCTT测定。

结果

乳果糖糖浆、红薯、馒头和玉米粉的OCTT分别为90.0±50.6分钟、237±64.9分钟、341.3±77.9分钟和352.5±59.5分钟，大米和肉末饭因仅少数研究对象产氢或氢值未升高而无法确定OCTT。OCTT与氢峰值呈负相关（r = -0.6625），与氢峰值时间和食物吸收率相关（r = 0.7668和0.8790）。
