Drinking 100 percent fruit juice does not affect blood sugar levels – Study

I know that a lot of people have strong feelings about juices – both positive and negative. I am kind of agnostic. I like pineapple-orange juice and drink it regularly. Otherwise, I am not much into fruit juice.


Juice found to have no association with major diabetes risk factors

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

A comprehensive data analysis quantitatively assessed the relationship between drinking 100% juice and blood glucose control. Using fasting blood glucose and fasting blood insulin levels as biomarkers for diabetes risk, the systematic review and meta-analysis included 18 randomized controlled trials (RCT) to evaluate the impact of 100% juice from fruits, such as apple, berry, citrus, grape, and pomegranate.

According to The American Diabetes Association, about 90% of the 29 million cases of diabetes in adults and children in the United States are considered Type 2. Type 2 Diabetes is a metabolic disorder where the body is unable to respond to insulin. The first line of defense for preventing and treating Type 2 Diabetes is following a healthy lifestyle. Eating right, exercising regularly and staying at a healthy weight are encouraged. U.S. Dietary Guidelines recommend consumption of a healthy eating pattern which includes fruits, vegetables, grains, low-fat or fat-free dairy and a variety of protein foods. A 4-oz. glass of 100 percent juice counts as one serving (1/2 cup) of fruit, and can complement whole fruit to help individuals add more produce to their diets. (my emphasis)


The study entitled “100% Fruit juice and measures of glycemic control and insulin sensitivity: a meta-analysis of randomized controlled trials” is available online. It was conducted by Exponent, Inc. on behalf of the Juice Products Association. The authors are Mary Murphy, MS, RD, Erin Barrett, PhD, Kara Bresnahan, PhD, MPH, and Leila Barraj, ScD of Exponent, Inc.

    I’d be more convinced if the study wasn’t funded by the Juice Board Assocl

  3. Tony, I enjoy reading many of your posts, but you need more depth than a juice board saying that juice isn’t bad. It take AT LEAST three to six full size apples to make single glass of apple juice. Do you realize how much sugar that is? People already have the tendency to drink fruit juice because they associate it with being “healthy.” It is MUCH MUCH better to eat fruit than to simply drink the juice . . . better to eat a single apple than to place the equivalent of six at one time in your system.
