Clinical Trial Summary

Assess the impact of 100% grape juice on postprandial glycemic response and subsequent appetite, food intake and cognitive function.

Description:

Investigators earlier clinical work and published literature suggest that the phenolic content and strong flavor intensity of 100% Concord grape juice hold potential beneficial effects on appetite and glycemia. Investigators aim to better understand the use of 100% grape juice modifies appetite and glycemia acutely and over the day using a 24 hour glucose monitor.
