Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this study, the postprandial glycemia and insulinemia caused by boiled potato with blue-fleshed or yellow-fleshed tubers, or a gel prepared with bilberries and potato starch, is studied in healthy males. Additionally, the appearance and metabolism of the flavonoids and their metabolites is studied in plasma and urine.
