19 Jan 2018 --- One hundred percent juice does not have a significant effect on fasting blood glucose, fasting blood insulin, or insulin resistance, according to new research. The findings are consistent with previous research indicating that 100 percent fruit juice is not associated with an increased risk of developing Type 2 Diabetes and support a growing body of evidence that 100 percent fruit juice has no significant effect on glycemic control. The study was conducted on behalf of the Juice Products Association and published in the Journal of Nutritional Science.
