Slowly and rapidly digestible starchy foods can elicit a similar glycemic response because of differential tissue glucose uptake in healthy men
Clinical Trials Thursday, September 27th, 2012American Society for Nutrition: 9/18/12
Previously we observed that the consumption of pasta and bread resulted in a similar glycemic response, despite a slower intestinal influx rate of glucose from the pasta. Underlying mechanisms of this effect were not clear.
Objective: The objective was to investigate the differences in glucose kinetics and hormonal response after consumption of products with slow and rapid in vivo starch digestibility but with a similar glycemic response.
Design: Ten healthy male volunteers participated in a crossover study and consumed 13C-enriched wheat bread or pasta while receiving a primed-continuous D-[6,6-2H2]glucose infusion. The dual-isotope technique enabled calculation of the following glucose kinetics: rate of appearance of exogenous glucose (RaE), endogenous glucose production, and glucose clearance rate (GCR).
