I'd agree with
@Resurgam, for me on a very low carb diet, fruits such as bananas, which are one of the higher sugar fruits, are completely off limits.
But you should always check all nutritional information or labelling
very carefully: sometimes values can be - or may even be intended to be - quite misleading: e.g. I have a freebie litre of coconut water with my current online shopping order - labelling says
4.6g carbs per 100ml, which doesn't sound so bad - but that's actually
46g per litre container which is a fairly generous day's worth of carbs for me. And that is just natural sugars from the coconut - nothing extra added!! (Advice I should have taken myself before I included this item!

) So you do also need to consider carefully
how much of a particular food or drink you're going to consume at a time, and also the total number of carbs in all the ingredients you are using... So if you are going to use just a little - fine, but otherwise, be careful - and test, test, test...
And a timely reminder - what may appear to be good and healthy for a non diabetic whose body can happily deal with carbs "correctly" could well be the equivalent of poison to us, who can't.
