Net carb puzzle?

[RobPL]

How do you work out the net carbs of something if the fibre is higher than the carb amount?
I just looked at some nuts for example and the carbs were about 7g while the fibre was about 9g.
Does this make them effectively zero carbs?
Thanks.

Net carbs is only relevant to US food labelling. For UK etc 'total carbs' is already 'net carbs' because the fibre is listed separately to the carb content.

That makes sense, thank you!
