== Possible improvements to make thing (a bit) more complex ==
The current API does not allow to store values for the prepared product, but it can be done on the OFF web site.
We should extend the API to allow to write nutrition facts for the prepared product.
The fields for the prepared product are the same than for the as-sold product, except "_prepared" is appended to the nutrient-id.
e.g. saturated-fat_prepared_100g, saturated-fat_prepared_value etc.
