La niña no tiene nada que comer. < Que?
So the sentence means "The girl doesn't have anything (nothing) to eat." Why is que used here? does Que + infinitive always mean "for the purpose of"... ?

Read this quick because I have to erase it before I get caught guessing, again!
To avoid saying "The girl must eat nothing", I think you are going for something like "The girl has nothing which to eat".
The sentence means "The girl has nothing to eat". If you remove "que", it would be (in a way, not literally) like removing "to" in the English version, and saying "The girl has nothing eat". But that's how bad the Spanish sentence would sound if you removed that "que"; this does not mean that "to" = "que", even though here they happen to be in the same place.
