Vinegar Lowers Glucose, Insulin Responses And Increases Satiety

November 2005

Drinking about three tablespoons of vinegar may lower glucose and insulin responses as well as increase satiety after healthy people eat carbohydrates, according to the results of a recent study. Volunteers drank 18, 23 or 28 mmol of acetic acid diluted in water and ate white bread that contained 50 g of carbohydrates after fasting overnight.

The bread was also served without the vinegar preparation as a reference meal. Blood samples were taken over the next two hours to assess the subjects' glucose and insulin levels. Satiety was also checked on a subjective rating scale.

The subjects' satiety scales were highest after the highest level of vinegar was ingested, being significantly higher than the reference meal at 30, 90 and 120 minutes after the subjects ate. There was also a significant dose-response relationship between high vinegar consumption and blood glucose levels and serum insulin responses, both being 25% lower at 90 minutes after the subjects ingested the highest level of vinegar.
