Keep an eye on the label, if there is one.
<4 grams of sugar is the best, but try some, IF you lose weight then it is ok for YOU, but if it sets you up for cravings, then X it out of your eating plan. Years ago I was taught that sugar had to be 4th or more in the list to be considered "legal"!
This is YOUR eating lifestyle and it is up to you to make healthy decisions.
Someone else here will be able to give you the facts on it, so this is only how and what I would do.
