Atkins says to stay far away from processed cheeses. Not only do they contain other starchy fillers, but many contain hydroginated oils. Those are the kind that can raise colesterol and do nasty things to the heart.

Instead of going for processed, use the real thing. If you like the convience of presliced, get cheeses from the deli. Yes processed cheese lasts forever, but that should be a warning sign. Most foods are not ment to last forever and that means things have been added or removed.
