legally, dont they have to try and be accurate at least? I mean, surely it wouldnt be legal to have something you know is, say, 1000 calories and put on the nutrition label that its 500 or something? Labels could be misleading, like not including stuff that comes with the product etc, but i think if you are careful and read it and know exactly what the information is referring to then you should be able to trust it right? I hope so
