title: The effects of dietary fibre on glucose tolerance in healthy males.
abstract: 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.
