Abstract

The purpose of this study was to determine if supplementation of a high glycemic load breakfast with resistant starch attenuates the glycemic response in young healthy adults. Twenty-one subjects, 23.8 + 3.3 yrs, reported for two days of data collection, having fasted 8-12h. On day 1(control), fasting BG was measured using glucometers, then subjects consumed 2 slices white bread and 250mL apple juice within 15min, the repeated BG measurement at 15, 30, 60, 90, and 120min after baseline. Day 2, the protocol was repeated, except that 10g of resistant starch supplement was added to the apple juice. There was no significant difference in fasting BG between the data collection days. There was no significant difference in the spike in BG (difference between peak and baseline) between the control and resistant starch supplemented meal(52.6±22.7 vs 52.0±20.6mg/dL, respectively) or incremental area under the glucose curve (137.2+78.9 vs 164.0+83.2mmol/L/120min,respectively).BG peaked at 15, 30, or 60min for all subjects. The resistant starch supplement had no effect on when BG peaked after the meal. The results of this study indicate that 10g supplementation of resistant starch does not affect the spike in BG or overall glycemic response to a high glycemic load meal.
