The purpose of this study was to evaluate whether the Glucometer Elite((R)) meter (Bayer Diagnostics, Kyoto, Japan) (POG) could be used for determining the glycemic index (GI) values of Chinese traditional foods, compared with the YSI (Yellow Springs, OH) glucose analyzer (YSI).
After consumption of either glucose or one of 11 test foods, the 2-h postprandial glucose responses were measured separately by POG and YSI. GI values and incremental area under the blood glucose response curve (IAUC) values were then calculated to make comparisons between POG and YSI.
The mean glucose concentration measured by POG was higher than that measured by YSI (5.54 +/- 0.03 vs. 5.30 +/- 0.03 mmol/L, P < 0.01). The mean IAUC calculated by POG data was also higher than that calculated by YSI data (112.93 +/- 4.04 vs. 106.76 +/- 4.06 mmol.min/L, P < 0.01). However, there were no differences in the mean GI value determined by POG and YSI data for each test food.
Although the glucose concentrations measured by POG were higher than that measured by YSI glucose analyzer, it seemed to be an appropriate instrument to determine the GI values of Chinese traditional foods. However, this conclusion should be cautiously applied to other kinds of glucose meters.
本研究旨在评估 Glucometer Elite((R)) 血糖仪（Bayer Diagnostics，京都，日本）（POG）是否可用于测定中式传统食品的血糖生成指数（GI）值，与 YSI（俄亥俄州扬斯敦）葡萄糖分析仪（YSI）相比。
在摄入葡萄糖或 11 种测试食品中的任何一种后，分别通过 POG 和 YSI 测量餐后 2 小时的血糖反应。然后计算 GI 值和血糖反应曲线下的增量面积（IAUC）值，以比较 POG 和 YSI 之间的差异。
POG 测量的平均血糖浓度高于 YSI（5.54 +/- 0.03 与 5.30 +/- 0.03 mmol/L，P < 0.01）。POG 数据计算的平均 IAUC 也高于 YSI 数据（112.93 +/- 4.04 与 106.76 +/- 4.06 mmol.min/L，P < 0.01）。然而，POG 和 YSI 数据确定的每种测试食品的平均 GI 值没有差异。
尽管 POG 测量的血糖浓度高于 YSI 葡萄糖分析仪，但它似乎是一种测定中式传统食品 GI 值的合适仪器。然而，这个结论应谨慎应用于其他种类的血糖仪。
