nutrition facts

The nutrition facts are presented by multiple fields per nutrition fact. Each nutrition fact is presented by a key, i.e. "salt", "fat", etc. The fields can also be found in the taxonomy translation file.

The fields can have the following structure:

  • key_value (string) - the standardized value of a serving of 100g (100ml) for type key (eg in json: "salt_100g":"0.19");
  • key_unit (string) - the units used in the other fields (eg in json: "carbohydrates_unit":"g"). Possible values are "kg", "g", "mg, "µg", "l", "ml", "%" or "";

key_value and key_unit are what is entered by the user, or passed to the write api, with the "key" and "key_unit" fields.

  • key (string) - the value for the nutrition fact key (eg in json: "fiber":"0.5");

Then "key" is a conversion in the default unit of the field (kJ or g)

  • key_serving (string) - the value of a serving for type key (eg: in json "carbohydrates_serving":"5.82"). The size of the servig is found in the serving field;
  • key_100g (string) - the standardized value of a serving of 100g (100ml) for type key (eg in json: "salt_100g":"0.19");

And "key_serving" "Key_100g" are values for the serving size or 100g. One of them is equal to "key", the other is converted.

  • key_label (string) - a more user friendly text explaining the

Only the nutrition facts that are actually found on the packaging are present in the interface.
