apple cider vinegar - lower blood glucose

Hi Guys,

Have a look...

Apple Cider Vinegar Before Meals
Vinager and Diabetes Study #1

The research team from Arizona state university, have recently shown that drinking apple cider vinegar slows the rise of blood sugar after the consumption of a high-carbohydrate meal.

The results are reported in the scientific journal Diabetes Care in 2004. (See reference 1)

Test Procedure - Vinegar and Diabetes

In this study 29 people were given a breakfast of orange juice and a bagel, which contained a total of 87 grams of carbohydrates.
Two minutes before the meal, half of the subjects were given 20 grams (about 4 teaspoons) of apple cider vinegar mixed with 40 grams water and 1 teaspoon saccharine. The other half were given a placebo drink.
A cross over trial was conducted a week later, at which time the placebo group received the vinegar.

The participants' blood sugar levels were measured before and after the breakfast. They were classified into 3 separate groups as follows:

* 10 people with type 2 diabetes
* 11 people with prediabetes (insulin resistant)
* 8 healthy control people (insulin sensitive)



Test Results - Vinegar and Diabetes

Analysis of the results showed that in all 3 groups the consumption of apple cider vinegar slowed the rise of blood sugar after the high-carbohydrate breakfast:

For the group with prediabetes, their blood sugar levels after the meal dropped by 34%.
For the group with type 2 diabetes, their blood sugar levels dropped by 19%.


Observations and Conclusions - Vinegar and Diabetes

Based on these results and two other recent studies, (see references 2 & 3), Dr Johnston thinks that the vinegar tonic interferes with the absorption of high-carbohydrate foods which reduces the blood sugar rise that normally occurs after a meal.

In her words," The acetic acid in vinegar may inhibit enzymes that digest starch so that carbohydrate molecules aren't available for absorption and are eliminated as fecal matter."
" Vinegar appears to have effects similar to some of the most popular medications for diabetes" (Acarbose or Metformin) continues professor Johnston and "Further investigations to examine the efficacy of vinegar as an antidiabetic therapy are warranted."

This is especially important given that a 50% increase in the number of Americans with type 2 diabetes is expected in the next 25 years.

In addition, the Diabetes Prevention Program and STOP-NIDDM, two recent large-scale trials, have shown that therapeutic agents used to improve insulin sensitivity in diabetes, may also delay or prevent the onset of type 2 diabetes in people with prebiabetes.

hadnt read this one, maybe ill keep taking acv for awhile or atleast if i want to cheat on my diet a little.

I've came across this study and others like it... I've been taking ACV liquid before meals sometimes, especially if I'm anticipating a higher glycemic load.
