There is a rumor circulating the internet that a single or 2 tablespoons of vinegar taken before meals will "kill" spikes in blood sugar levels as well as balance type 2 diabetes. The truth is that starting a meal with vinegar, a food containing vinegar,

The way to describe how acidic foods affect or change the glycemic index... is saying it is unexpected. The way
vinegar decreases blood sugars is by reducing the
absorption of digested sugars from the large intestine. The acid in vinegar is counteracted by bicarbonate in the intestines, and minus the bicarbonate, glucose doesn't pass into the bloodstream quickly. Eating a vinegary pickle, or even taking a little bit of shot glass of vinegar before a meal will lower post prandial blood sugar increases.
All that said, this's the summary of just how acidic foods work: what happens is acidic foods greatly reduce the glycemic index of a carb food, or a food, by one third. The reason lies in how the stomach of yours as well as digestive system work (see above). Acidic foods retard the emptying of your tummy. The meals slows down the digestion of yours, which slows down how quick your blood sugar levels rise.
Here's a summary of foods, including vinegar, which are acidic:
Several of the sour foods, including chutney, some of the pickled vegetables as well as sweet pickles have very high sugar added... thus, it wouldn't be advisable to eat large amounts of these.
