This is why in the EU and other places the amount of calories, carbs and sugars, proteins, salt, fat and saturated fat, and fibre **MUST** be reported per 100g. And the net weight must also be present.

They may also give these values per “serving”, but only alongside the 100g values.

I was eating some chocolate today that listed the serving size as 3 squares of chocolate. The bar is made in rows of 4 squares…

But the bar was 85g (and yes I ate the whole thing).

I thought something similar had recently been brought in in the US too, residually in light of stuff like Tic Tacs have “zero” Calories per services despite being almost 100% sugar. Please tell me I didn’t imagine that ruling from several months ago…
