“…Recent studies suggest that the quality of fibre may be as important as the quantity. Thus high viscosity preparations such as pectin and guar seem to have a considerable post prandial hypoglycaemic effect [4,8,20] in contrast to cellulose and its lowviscosity derivatives which do not [20]. The fibre supplementation used in the present study was a wheat bran preparation.…”

“…The need both to reduce the percentage of available carbohydrates in the diet of diabetic patients and to avoid nutrients containing concentrated refined carbohydrates has been long recognized, but despite these measures many patients continue to show poor glycaemic control. Dietary fibre has been reported to benefit control in "chemical diabetes" [8], non-insulin dependent diabetes [3] and insulin-dependent diabetes [9,10,11,12]. Here we report a study comparing the effects of high fibre diets on diabetic control in patients with stable or labile insulin-dependent diabetes.…”

Seven stable and 10 labile insulin-dependent diabetic patients were submitted to 2 dietary regimens which were given in random order and maintained for 10 to 15 days. During one period ("control") patients were given their usual diets. During the other period patients received a fibre supplemented diet ("test"). The fibre supplementation was calculated to provide 1 g dietary fibre per 15 g available carbohydrate. For each period, diabetic control was estimated from: (i) daily gtycosuria; (ii) % giycosylated haemoglobin, (iii) insulin requirements, (iv) frequency of hypoglycaemic episodes and (v) circadian blood glucose levels..Dietary fibre supplementation resulted in: (i) decreased glycosuria in both stable (12.8 __+ 5.6 g/day vs 25.5 _+ 6.9 P < 0.01) and labile diabetics (35.8 + 10.5 g/day vs, 52.5 + 7.1, P < 0.02); (ii) a significant decrease in blood glucose at 1430h (P < 0.02) in stable and at 1430 h (P < 0.05) and 2030h (P < 0.01) in labile diabetics. The percentage of glycosylated haemoglobin was identical in stable (10.8 _+ 1.0%) and labile diabetics (10.7 +_ 1.0) and was slightly depressed with the fibre supplemented diet (9.5 + 0.8 and 9.3 + 0.6 respectively). The mean blood glucose during the control period was not significantly different in stable (186 + 28 rag/100 mt) and labile diabetes (221 + 24 rag/ 100 ml) and did not change significantly with fibre treatme'nt. The results show that the control of stable and labile diabetes is improved to a similar degree by dietary fibre. This effect results mainly from a decrease in post prandial hyperglycaemia after lunch and dinner.

“…The heat stable alpha and beta amylases in sweet potatoes (Hagenimana et al, 1994) contributing to increase the maltose (Eo et al, 2016) content in boiled sweet potatoes may also contribute to high peak and high GIs. The dietary fiber contribution in boiled tubers thus is not adequate to overcome the effects of above factors to reduce the GI (Monnier et al, 1978).…”

Sweet potatoes are one of the major tuberous roots consumed around the world. The objective of the present study was to determine the nutritional composition, glycaemic indices and glycaemic loads of selected Sri Lankan sweet potato varieties, in order to address the inadequacy of information and the controversial findings on glycaemic indices. Nutrient composition (moisture, ash, digestible carbohydrates, dietary fiber, crude protein and fat) of boiled sweet potatoes, GI and glycaemic loads (GL) of nine varieties were determined using standard methods. Digestible carbohydrate content ranged between 29-88% on dry weight. Ash, crude protein and crude fat contents of the varieties ranged between 3.1-5.0%, 3.0-5.9% and 2.6-5.3% on dry weight basis (DW) respectively. The total dietary fiber content was above 9.5% DW in the studied varieties. Moisture content of boiled sweet potato tubers were 72-81% on fresh weight basis and both the GIs (86-119) and GLs (>20) were high. However, the GL reduced to medium or low when considering an actual edible portion for all the varieties except for two varieties. Sweet potatoes are a good source of highly available carbohydrates which elicit high GIs.

“…On the other hand, the effect of fiber supplementation has been seen even during very short studies. Monnier et al showed that the addition of fiber to an oral glucose load improves the pattern of the oral glucose tolerance test by blunting the peak blood glucose, prolonging the time interval to reach the peak blood glucose, and decreasing the rate of blood glucose rise [13]. …”

BackgroundNutritional therapy is an important component of diabetes management. There is data to suggest that fiber content of foods may affect glycemic response.Materials and methods10 children, diagnosed with type 1 diabetes, participated. In the first phase of the study, children followed their usual meal plan. In the second phase, subjects followed the same meal plan except that fiber was added to the diet using a powder supplement (wheat dextrin). Data was collected using a continuous glucose monitoring device. The blood glucose excursion level following each meal was compared between the two phases of the study by fitting a repeated measures regression model. The incidence of hypoglycemia was also compared by fitting a logistic regression model.ResultsThere was no difference in the mean blood glucose excursion after meals or the incidence of hypoglycemia between the two phases. There was a strong negative correlation between the amount of fiber supplemented and the mean maximum post-prandial blood sugar after the lunch and breakfast meals (Spearman rank correlation coefficient = −0.86 lunch and −0.76 breakfast).ConclusionOur study did not show an overall decrease in glucose excursion or incidence of hypoglycemia with fiber supplementation. We did find a strong negative correlation between the amount of fiber added during the supplemental phase and the mean maximum post-prandial blood sugar after the lunch and breakfast meals. We speculate that different types of fiber may have different effects on blood glucose with wheat dextrin having a greater dampening effect.
