Another challenge for eating well while working or travelling abroad is that there is no single international system for food labelling! I only discovered this recently.
In the UK and EU, labels will say (amongst other things) "Carbohydrate" and give a number, and then there will be a sub-number for "of which sugars", and then a separate number for "Fibre".
Turns out, though, that fibre is technically a carbohydrate-- it just doesn't matter to diabetics, because it's 'unavailable carbohydrate', meaning your body can't turn it into glucose.
So, for example, Japanese food labelling gives a number for "Total carbohydrate", and then gives sub-numbers for fibre and for available carbohydrate-- the latter being what UK/EU food labels mean when they just say "carbohydrate".
The worst are US labels! They give a number for "Total carbohydrate", and then give a sub-number for "Dietary fiber"-- so, to get the information you need as a diabetic, you have to subtract the latter from the former.
Is there some sort of travel guide for diabetics, with country-specific information that might help neilnst?
