Apple Cider Vinegar May Help Manage Blood Sugar in Those at Risk for Type-2 Diabetes
While previous studies have suggested that vinegar may help control blood sugar, there previously had been no long-term studies to verify that. Now, a recent study has found that ingesting apple cider vinegar at mealtime may reduce fasting glucose levels in people who are at-risk for developing type-2 diabetes.
Participants in the study included 14 people at risk of developing type-2 diabetes. They consumed either a 750 mg apple cider vinegar beverage sweetened with Stevia or a control pill containing 40 mg of acetic acid twice daily at mealtime over the course of 12 weeks.
The researchers took fasting glucose blood measurements at the onset and conclusion of the study, while the participants recorded their fasting glucose levels and glucose levels two hours after eating every day.
The researchers found a notable difference in average change in fasting glucose, with the beverage group recording an average change of -0.91 nmol/l and the control group recording an average change of -0.26 nmol/l. However, there was no difference between the two groups when it came to insulin, glycated hemoglobin or blood glucose levels two hours after eating.
Additionally, fasting breath hydrogen at the conclusion of the study was 19% higher in the beverage group when compared with the control group, suggesting higher colonic fermentation in the beverage group. This indicates that the anti-glycemic effect of vinegar is at least partly related to improving carbohydrate absorption.
Researchers from Arizona State University conducted the study. It was published online ahead of print on August 30, 2013, in Journal of Functional Foods.
Apple cider vinegar has been used in a variety of traditional medicines for hundreds of years. Previous studies suggest that vinegar may help lower cholesterol, lower blood pressure, and help with weight loss.
Apple cider vinegar isn’t an especially tasty supplement to add to your diet. However, there are more and more commercial drinks that integrate vinegar into their recipe, making it significantly more palatable. Additionally, vinegar can always be added to things like salad dressings for a delicious, healthier option.
