Investigation of PJ vs. Sugar on Glucose Levels in Healthy and Prediabetic Subjects

This study aims to measure the effects of PJ vs. sugar on glucose and insulin levels in apparently healthy normal weight and prediabetic overweight and obese subjects. Participants will be asked to consume one serving of PJ, sugar mix and water separated by one week of beige diet without PJ consumption (crossover design). The PJ will be provided by POMWonderful. Timed blood collections over a three-hour period following the juice/sugar/water consumption will be used to measure how PJ vs. sugar mix vs. water affects glucose metabolism/insulin sensitivity in human subjects.
