>Apple Cider Vinegar Nutrition Snapshot
Apple cider vinegar is very low in calories and macronutrients. According to USDA data, 1 tablespoon (15 g) of cider vinegar provides approximately:
~3 calories
Less than 1 gram of carbohydrates
Negligible protein and fat
Small amounts of minerals such as potassium
These values are for standard cider vinegar; artisanal or organic brands may vary slightly but remain very low in calories and macronutrients. The benefits of ACV appear to come more from its acetic acid, organic acids, and plant compounds than from its vitamin or mineral content.
