Previous studies have shown that the addition of non-absorbable carbohydrate (NAC) to test meals decreases the glucose and and insulin response both in normal and diabetic subjects. However, these studies appear to have used brain in the basic test meal without a knowledge of the effect of bran itself or of the added NAC alone. In the present investigation bran alone, pectin alone, guar alone and pectin with guar have been studied. Guar alone added to the test meal significantly lowered blood glucose at 90 minutes. Pectin alone did not have a significant effect. Pectin and guar together resulted in a blood glucose lower at 30 minutes and greater at 120 minutes. No significant changes in insulin response were noted to our study. It appears that NAC alters the glucose response to a given meal, but the extent to which this occurred in the present study was less than in previous studies. The differences may reflect synergism between bran and other NAC's to lower blood glucose response after a meal.
先前的研究表明，在测试餐中添加不可吸收碳水化合物（NAC）可降低正常人和糖尿病患者的血糖及胰岛素反应。然而，这些研究似乎在基础测试餐中使用了麸皮，却未了解麸皮本身或单独添加的NAC的作用。在本研究中，对单独的麸皮、单独的果胶、单独的瓜尔豆胶以及果胶与瓜尔豆胶进行了研究。单独添加到测试餐中的瓜尔豆胶在90分钟时显著降低了血糖。单独的果胶没有显著影响。果胶和瓜尔豆胶共同作用使血糖在30分钟时降低，在120分钟时升高。在我们的研究中未观察到胰岛素反应有显著变化。似乎NAC会改变对特定餐食的血糖反应，但在本研究中这种情况发生的程度小于先前的研究。这些差异可能反映了麸皮与其他NAC之间在降低餐后血糖反应方面的协同作用。
