Abstract

This 12-week pilot study examined effects of vinegar on markers of type 2 diabetes in at-risk adults. Participants ( n= 14) ingested 750. mg acetic acid as a vinegar drink or a control pill (40. mg acetic acid) twice daily at mealtime. Blood glucose (fasting and 2-h postprandial) was recorded daily. Fasting blood collected at weeks 0 and 12 was analyzed for insulin and glycated hemoglobin. Average change in fasting glucose was reduced in the vinegar group versus control group (-0.91 ± 0.27 versus -0.26 ± 0.17. mmol/l) ( p= 0.05). Average change in 2-h postprandial glucose, insulin and glycated hemoglobin did not vary between groups. Fasting breath hydrogen at week 12 was elevated 19% in the vinegar group versus control group suggesting an increase in colonic fermentation in the vinegar group. These data indicate that vinegar, a simple addition to meals, has antiglycaemic effects in adults at-risk for type 2 diabetes, possibly related to carbohydrate maldigestion.
