Before or Concomitant Drinking Greenleaf Juice with Rice Reduces Postprandial Blood Glucose Levels in Healthy Young Women

Abstract

The purpose of this study was to examine how green leaf juice drinking affect the postprandial blood glucose. Postprandial hyperglycemia causes vascular endothelial damage and chronic inflammation, promoting atherosclerosis, regardless of the presence of diabetes. Some ingredients in greenleaf juice have been reported to suppress blood glucose levels; however, the effect of greenleaf juice on reducing blood glucose levels in healthy individuals is unclear. We observed changes in postprandial blood glucose levels in 13 healthy young women who drank greenleaf juice before or concomitantly with rice. Compared to water, greenleaf juice consumption reduced blood glucose levels at 90 and 120 min after rice consumption, with no difference regardless of the time of greenleaf juice consumption. Greenleaf juice may be one of the most convenient and cost-effective methods for reducing postprandial blood glucose in healthy people.
