Wellness influencers have claimed that eating pickles before a carb-heavy meal can help prevent blood sugar spikes.
The acetic acid in vinegar, not so much the pickle itself, might be the key to explaining why.
Several small studies found that vinegar at meal times seemed to have a positive effect on insulin and after-meal blood glucose levels . It might even help with fasting blood sugar, too.
Acetic acid may help with a few things:
It may slow down the rate at which food leaves the stomach, which prevents it from reaching the small intestine too fast. This may prevent spikes because glucose isn’t being absorbed as fast.
It may stop or slow certain digestive enzymes that break down starch, like α-amylase and disaccharidases.
