This single-blind crossover-designed study wants to investigate the postprandial effect of functional bread in healthy overweight adults. Therefore, four types of bread, consumed by the participants, have added galactomannan in different amounts and viscosities, and one bread is the control bread.~The participants arrive after an overnight fast and before the consumption of bread, a fasting blood sample is taken.~After the ingestion, blood samples are taken at specific times. The area under the curve of the postprandial glucose is expected to differ between the functional breads.
This study investigates whether bread with added galactomannan, a soluble fiber, can reduce the postprandial glucose response in healthy overweight adults.
