Fast food has its place in this world. It can make you feel like your not hungry, when you are hungry. But you'll absorb no vitamins, potassium, iron, and other essential nutrients from any of the major fast food chains. Maybe protein and carbs....actually I guaruntee it, but amino acids? No, probably not.
I'm not a health nut or anything, but I do like to eat real food...because real food, is well, real food. Anything that isn't actually cook (aka takes time), probably isn't the best thing to eat.
