Yes, pretty much all the processed packaged food that's sold here comes with heavy labelling. Such as "High in sugars"; "high in calories"; "high in saturated fats" and the likes. Same for sodas.
And from what I've seen it has been rather effective.
But also we have a big overweight and obesity problem here. Actually, depending on where you see the numbers, we're just as bad or even worse than Mexico and the USA.
Just saw the numbers... 74% of the adult population ooh we're fucked...
So maybe it's not being that effective Either that or without the labelling it would be even worse.
