Apple cider vinegar
In a study with the American Diabetes Association, apple cider vinegar to help improve insulin sensitivity after a high-carbohydrate meal was investigated.
The study involved participants who were either insulin sensitive, insulin resistant or with type 2 diabetes.
Participants were randomly assigned to consume either 20g apple cider vinegar or a placebo drink after a meal.
Blood samples were collected at fasting and 30- and 60-min post meal for glucose and insulin analyses.
The study found compared with placebo, vinegar ingestion raised whole-body insulin sensitivity during the post meal interval in insulin-resistant subjects and improved this parameter in subjects with type 2 diabetes.
It was concluded that taking 20g of apple cider vinegar diluted in 40ml of water could lower blood sugar after meals.
