Why do cake and brownie mixes have nutrition information for before you make it?

The law is that all foods have to have nutritional info on the label. I know it doesn't make a lot of sense for mixes, where other ingredients will be added, but in general I think the law is a good idea. The big food manufacturers fought long and hard against this law, but these days I see a lot of people looking at these labels in the supermarket.

Besides, all you add to cake and brownie mixes is usually an egg and some water. So if you wanted, ti would be easy enough to look up the nutritional info for the egg and add it. At least the info is available!

I don't know if the law requires both, but the 'before mixing' information is there so that people who use different ingredients from the recommended ones on the box can figure what nutrients the altered cake has.

For instance, some people use applesauce instead of egg and oil in a boxed cake mix. Or they'll add powdered milk to brownies. If you know what's in the applesauce or milk powder, you can then figure out how many calories, how much fat or calcium, etc., there is in the finished cake.

Since the mixes are technicaly edible then they have to have nutritional information on them.I'm sure that there are people out there that eat dry cake mix.It takes all kinds to make the world go round.
