In vinegar the carbs and sugars are metabolized into alcohol first then into acetic acid.
As
@jennyema says, no.
There are probably some anti-oxidants in vinegar but not anywhere near what is in the apple. An apple also provides a sense of fullness in the stomach with the fiber and the carbohydrates.
An active vinegar (you'll notice the mother near the bottom of the container-a semi-transparent gel like blob) will encourage good gut bacteria that will help a person digest their food. It is a probiotic. It will also assist immune function and provide a healthier gut lining.
Both the apple and AC vinegar are very good for you. I try to get both every day, one way or another.
