简要总结
Assess the impact of 100% grape juice on postprandial glycemic response and subsequent appetite, food intake and cognitive function.
详细描述
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.
