To understand how apple cider vinegar benefits your digestive system, we should look at how it is made. ACV, like all fermented foods, takes advantage of controlled spoilage, in which yeast digests the sugar in apples and converts it into alcohol. Then, a bacteria called acetobacter converts the alcohol into acetic acid.
By virtue of this process, ACV counts as a probiotic. Probiotics are those “good germs” that you want working for you in your gut. They help control germs that can make you sick and assist with nutrient absorption.
