To test whether the glycaemic index is altered by the amount of carbohydrate, meals containing 25 and 50 g carbohydrate as white rice and white bread were taken by seven non-insulin-dependent diabetic subjects. The glycaemic indices to parboiled white rice corresponding to 25 and 50 g carbohydrate were similar, being 55 (SE 10) and 60 (SE 8) respectively. The incremental areas of blood glucose (above basal) to parboiled white rice were significantly lower than to white bread after both an amount corresponding to 25 g carbohydrate (85 (SE 24) mM x 180 min v. 181 (SE 55) mM x 180 min; P less than 0.01) and to 50 g carbohydrate 226 (SE 29) mM x 180 min v. 423 (SE 76) mM x 180 min; P less than 0.01). Similar insulin response areas to 25 g carbohydrate given as parboiled white rice and white bread were found, whereas 50 g carbohydrate as white bread caused a significantly higher insulin response area than parboiled white rice (P less than 0.05). In conclusion, the glycaemic index of parboiled white rice is not affected by the amount of carbohydrate ingested, at least under the present study conditions.
为了测试血糖指数是否会因碳水化合物的量而改变，7名非胰岛素依赖型糖尿病受试者食用了含25克和50克碳水化合物的白米饭和白面包餐。对应于25克和50克碳水化合物的半熟白米饭的血糖指数相似，分别为55（标准误10）和60（标准误8）。在摄入相当于25克碳水化合物的量后（85（标准误24）毫摩尔×180分钟对181（标准误55）毫摩尔×180分钟；P<0.01）以及摄入50克碳水化合物后（226（标准误29）毫摩尔×180分钟对423（标准误76）毫摩尔×180分钟；P<0.01），半熟白米饭的血糖增加值（高于基础值）显著低于白面包。发现食用相当于25克碳水化合物的半熟白米饭和白面包时胰岛素反应面积相似，而50克碳水化合物的白面包导致的胰岛素反应面积显著高于半熟白米饭（P<0.05）。总之，至少在本研究条件下，半熟白米饭的血糖指数不受碳水化合物摄入量的影响。
