And Vinegar

Vinegar is a sour liquid made by fermenting ethanol (alcohol) in liquids like wine, cider, or grain mash. The alcohol is first converted to acetic acid by bacteria, then further fermented into vinegar. It has been used for thousands of years as a food ingredient and preservative.

Vinegar is primarily used as a flavor enhancer, adding a sharp, acidic taste to foods. It's also used as a preservative, inhibiting the growth of bacteria. You'll find it in salad dressings, marinades, pickles, sauces, and snack foods like chips and pretzels.

Vinegar is generally recognized as safe (GRAS) by the FDA for use in food. While some studies suggest potential benefits like improved blood sugar control when consumed in moderation with meals, evidence is mixed and more research is needed. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated vinegar, but did not set a numeric acceptable daily intake (ADI). High concentrations of undiluted vinegar can be harmful.
