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

Pre Diabetes Clinical Trial

Official title:
Exploratory Study to Determine the Bioavailability of Sugar From Pomegranate Juice (PJ) vs. Sucrose

Clinical Trial Summary

Pomegranate fruits and products, including juice, tea, wine and extracts are widely consumed and recognized for their health benefits. Pomegranate fruit possesses strong antioxidant, anti-inflammatory and antiproliferative properties. The effects of pomegranate on type 2 diabetic (T2DM) conditions have previously been reported. Although 8 oz. of Pom juice (PJ) contains 36.9 g of sugar, 12-week PomJ supplementation did not change plasma advanced glycated end-products, fasting glucose and HbA1C, but reduced lipid peroxidation in T2D subjects. Additionally, acute PJ consumption has been shown to lower postprandial glycemic response of a meal with high glycemic index (GI) and lower fasting blood glucose, and long-term PomJ consumption did not worsen diabetic markers. However, a large knowledge gap still exists regarding the form of sugars in PJ and the hormonal responses to PJ consumption in different physiological conditions. Therefore currently the consumption of PJ is not recommended for individuals with T2DM. This clinical study will focus on the short-term effects of PJ consumption on different diabetic variables to further evaluate the health benefits of PJ for T2DM.

Clinical Trial Description

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. ;
