I hope this is the right way to report this.
This page:
https://wiki.openfoodfacts.org/Nutrients_handling_in_Open_Food_Facts
Says of the nutriment fields:
{nutrient-id}: the value converted in the default unit (currently kJ for all energy fields (including energy-kcal), otherwise gram).
Below it adds in "Possible improvements":
Store the energy-kcal values in kcal, without converting them to kJ
However, checking one or two cases from the API suggests that the energy-kcal field is in kcal, not kj, as it is approximately 4.18 times smaller, which would be about the right ratio if they were in kcal/kj, whereas would presumably be a massive discrepancy if they were both in the same units.
Examples:
Also, both fields are missing from:
https://wiki.openfoodfacts.org/API/Full_JSON_example
So I am guessing the API has changed and the wiki is now out of date?
Would you be able to confirm either way? I'm currently writing a diet diary application which would use this information, and I will be assuming that the kcal field is in fact in kcal unless you say (or I discover) otherwise.
Thanks!
