Short-term Effect of Pomegranate Juice on Blood Sugar and Its Controlling Hormones in Pre-diabetic and Type II Diabetic Patients.

Fresh pomegranate juice at 1.5 mL/kg of body weight was administered by recruited healthy individuals and patients with type 2 diabetes of fasting serum glucose between 7.1 and 15.8 mmol/L after approximately 12 hours fasting. Blood samples were collected in plain tubes before (-5 minutes) and at 1 and 3 hours after drinking pomegranate juice. Blood samples were centrifuged and serum was collected and stored for glucose and hormonal analysis. Patients were recruited from those of earlier stages of type 2 diabetes, and many of them already drink pomegranate juice as of its benefits for their health).

The exclusion criteria included subjects with renal or hepatic disease, pregnancy, treatment with insulin, and hormone therapies. Participants who had either smoked cigarettes or taken antioxidant supplements, lipid-lowering drugs, and oral hypoglycemic agents, such as metformin (glucophage) or sulfonylureas, within the preceding 12 hours were also excluded.

The study was explained to all of the recruited subjects by the clinical researchers, and written informed consent was obtained prior to enrollment. Approval for the study was provided by the IRB Committee at Jordan University of Science and Technology (Irbid, Jordan).
