How does the net carbohydrates field work across providers?

The nutrition data model includes a macros.net_carbohydrates_g field even where the docs lag.

The nutrition data model includes a macros.net_carbohydrates_g field even where the docs lag. Documentation is updated periodically as fields are added.

Providers differ: some report net carbohydrates separately from total carbohydrates, while others put net values in the carbohydrates field, so check per-provider behaviour.

Note that legacy client library packages are not actively updated as newer packages are introduced.
