200mls of balsamic vinegar is quite a lot for a dish, how many does the dish serve? Balsamic Vinegar does have added sugar, that being said i do use it for some dishes like marinade or salad dressings, and even then it's only quite a small amount.  200mls of balsamic vinegar will have a toal of 13.5g of fructose.  You should subsitute red wine vinegar instead although you'll get a different flavour.
