The acute effect of a B-glucan-enriched oatbread on gastric emptying and postprandial glycemia – a randomized crossover trial in healthy adults

Rationale: The oat-derived dietary fiber β-glucan has been shown to reduce postprandial glycemia, however, the mechanisms responsible for the blood glucose-lowering effect are not completely clear. Thus, the aim of this study was to investigate the acute effect of a β-glucan-enriched oatbread on gastric emptying rate and the subsequent postprandial glycemic and insulinemic responses.
