There's no rules. It's up to you to find a way of eating that suits both your life and your bg.
At 8 g of carbs each they are not too bad. If you, for example are someone who finds your bg and weight is controlled by no more than 50 g carbs per day then if one fits so be it. If however you find that one makes you want more and that leads to 2 or or more sweet things creeping in then you may decide you don't want to eat them. Some people struggle that anything sweet, whether it has carbs or not (eg sweetners) just makes them crave more and more and slowly they find bg and weight rising.
So ask yourself
Am I happy with my bg, generally and especially after eating this?
Am I happy that i am controlling my weight?
Am I happy that these aren't triggering an insatiable sweet tooth?
If you are happy then continue, if not you decide what to do. You are the boss of you and your body, no one else is.
