This tutorial is a bit outdated and for an older version of the software.
But the label creation has been renamed to Reports. So in the main dialog press the Reports button.
First, I don’t store info on mono-unsaturated or poly-unsaturated fats in the ingredients.
So, to get this in the reports you must first add this yourself.
In the Settings dialog you can define up to six user ingredient variables. So, you can use these for your purpose.
This will also only work for you local user ingredients as you can not change the standard ingredients.
After you set this up you can add this to the reports when creating labels.

Translating ingredients in the label system is a good idea. I’m not sure exactly how to implement this but I will think on it and try to find a solution.
Also, translation of the standard ingredients are in the online language database so that should be ok.
Translation of user ingredients is not supported and I will have to add that as well for this to work for you.
Good ideas and I will certainly have a look at it.
//Thanks

This is the most time consuming thing ever!

It would be great if I could manually add the translations for each ingredient in the Ingredients database so I can generate the label for multiple languages.
