Nutrition Facts for Diet Pop

I absolutely love diet soft drinks. If I were more active and ate less other stuff, I'd drink non-diet pop, but given that I'm quasi-sedentary and I like to eat other stuff, I drink a lot of diet pop.

Whoever writes the "Nutrition Facts" on the can I am presently drinking either has a very good sense of humour and/or is being told to say this by some legal eagle or bureaucrat:

Not a significant source of saturated fat, trans fat, cholesterol, fibre, vitamin A, vitamin C, calcium, or iron.
