In new zealand we have http://www.foodstandards.govt.nz/consumer/labelling/panels/P...
and Mcdonalds for instance... https://mcdonalds.co.nz/sites/mcdonalds.co.nz/files/Nutritio...
which is great if you care about it. But generally if you care about such things you have a pretty good idea for most foods anyways. Though, there are a few foods that it's not entirely obvious there's lots of sugar in them.
