VERSAFIBE™ 2470 dietary fiber is a resistant starch type 4 derived from high‐amylose maize. This product is high in dietary fiber (70% TDF, AOAC 2009.01 method) and can be used in a variety of bakery applications. The objective of this study was to investigate the effect of VERSAFIBE 2470 dietary fiber on the glycemic response of healthy adults (n=28). This study was conducted in accordance with the ethical principles outlined in the Declaration of Helsinki and approved by the Institutional Review Board (IRB Services, Aurora, Ontario). All subjects provided informed consent prior to enrolling in the study. The primary outcome was the two‐hour (baseline to 120 min) intravenous blood glucose incremental area under the curve (iAUC 0‐120min ) after consuming a muffin top made with VERSAFIBE 2470 dietary fiber (11.6 g TDF, treatment) or a muffin top made with conventional refined wheat flour (0.9 g TDF, control). The muffin tops were matched for total weight, total carbohydrate, sugars, protein, and fat. Subjects were randomly assigned the treatment order. During each 24‐hour study period, subjects consumed a standard evening meal, fasted for 12 hours, and arrived at the study clinic the following morning. Serum glucose, serum insulin, and capillary glucose were measured at 0 min, 15 min, 30 min, 45 min, 60 min, 90 min, 120 min, 180 min and 240 min after muffin top consumption. Breath hydrogen and methane concentrations were measured at 1, 2, 3, 4 and 24 hrs. The subjects completed a seven day washout between treatments. Product perception (sensory evaluation and overall liking) was similar between the two treatments. Consumption of the VERSAFIBE™ 2470 dietary fiber muffin top resulted in a significant 33% reduction in post‐prandial serum glucose iAUC 0‐120min and an 8% decrease in maximum glucose concentration (C max 0‐120min ) versus the control muffin (p = 0.037, p= 0.007 respectively). Correspondingly, consumption of the VERSAFIBE™ 2470 dietary fiber muffin top reduced post‐prandial serum insulin iAUC 0‐120min by 38% versus the control muffin (p < 0.001). Capillary glucose iAUC 0‐120min did not differ between treatments. Serum glucose, serum insulin, and capillary glucose values were significantly lower at individual time points when the VERSAFIBE 2470 dietary fiber muffin top was consumed versus the control muffin top. There were no differences in breath hydrogen or breath methane after consumption. This study demonstrates that inclusion of a practical dose of dietary fiber (11.6 g TDF) from VERSAFIBE 2470 dietary fiber in a bakery product significantly reduced postprandial glucose and insulin responses in healthy adults.
