Resistant starches are complex partly indigestible carbohydrates that have shown promise in improving digestive health, maintaining blood glucose concentrations, and increasing gut transit time. In this study we used resistant starches to evaluate blood glucose response. A randomized blinded cross over human feeding study was conducted for four weeks using 50 g of conventionally and cross bred resistant starches derived from maize, fed in a pudding‐like breakfast product to 11 healthy, non‐obese subjects, 6 men and 5 women. Blood draws were taken at predetermined intervals for a period of four hours. Due to interpersonal variability, there was no significant difference among treatments; however, notable trends were observed. There was a postprandial peak in glucose response 30–45 minutes after every treatment. When participants' blood glucose levels were averaged across weeks the treatment with the highest digestion resistance (~25%) showed the lowest postprandial peak indicating a lower glycemic response to a resistant starch meal. Overall, participants reported no adverse gastrointestinal affects in response to resistant starch meals. Lower glucose responses with minimal to no adverse gastrointestinal effects supports the role of resistant starches in potentially improving postprandial blood glucose and maintaining health.
