It could reduce your blood sugar
Research indicates that apple cider vinegar can help your body break down sugar by increasing the efficiency of insulin. The Journal of the American Association of Diabetes published study results that showed significantly lower post-meal glucose levels in participants who took 20 grams of apple cider vinegar after a eating a carb-heavy bagel.
Other studies have backed these results. Apple cider vinegar will not cure diabetes or replace diabetes medication, but it can be a powerful preventative and a reasonable addition to a diabetes-friendly diet.
