That is 100% right.This makes my brain hurt. I'm in the UK and followed the above advice of counting all carbs, kind of overlooking the (of which sugars) Is that right?
If you are using the nutritional values on the packaging in the UK, this is exactly what you need to do.
If you are ever tempted to look up the carb content online because, for example, your apples do not have a nutritional content label, I recommend using the website from a UK supermarket.
Sorry for making your brain hurt 🙂
