But, my personal worst food to eat is potato chips, prefer the thicker ones with ridges. I've had to drop those from my menu though because the heavy salt content contributes to kidney stones
. I also absolutely love Long John Silvers or Captain D's fish & chips. We don't have any of those in my hometown so if we're traveling and see one my wife will indulge me (she hates the stuff).
I also have one traditional food that has no nutritional value. To me it's not summer unless I've had a SnoCone. I've had at least 1 every summer since I was a child which covers many many years. This year I got to do the exotic version, Shave Ice, when we went to Oahu this year. Now those people know how to do SnoCones!
