==== Data sources for ingredients lists ====

The possible input sources for the ingredients lists are:

* Ingredients lists typed in by users
** Time consuming and not pleasant task, especially on mobile
** Can contain typos, but usually typed ingredients lists are very close to what is written on the product
* Ingredients lists given by manufacturers in data files
** Usually of very good quality, but depending on manufacturers, can contain typos and sometimes formatting errors
* Photos of product labels
** Photo quality varies a lot
*** Some products are hard to photograph (round cans and bottles, foil bags etc.)
*** Sometimes very poor lighting, orientation, camera, focus etc.
