You can have junk food but not in regular intervals.......
but if u have excess(too much) of it is bad........
as elders always say''excess of anything is not good'' 
so control on having too...much junk food and snacking :)
and back to your question..............i would say its neither of good or bad but just control on having it or else it can be harmful for your body and only then it is bad....
thats all i had to say:) hope i answered your question and good luck;-)
