What country is this from? That's a rather confusing nutrition label; serving size is 15g but they show the nutrition facts for a 100g serving? It would make more sense to do the two column setup like the US does: show the info for one serving, and then the info for how much people actually eat (usually the entire package).
Per 100g is quite normal across Europe too (because you can kinda treat the values like a percentage or at least compare to any other product). We usually in the UK have per 100g and either per serving size or package size.
While ideally you'd want a column for serving size, package size, and per 100g, if you're only gonna have one it should definitely be the per 100g since that's the only one that allows you to easily compare between different brands and products.
