I guess I'm a little confused by the interpretation of junk food, too
I define junk food as being in the snack food category, but not considered a healthy snack food (like Granola bars), so while some may say fast food places serve junk food, I don't. And I don't call a beverage food, so that rules pop (soda) out. And anything homemade I would hardly consider junk food, so homemade brownies and cookies are not on my junk food list either. And candy... well, that's candy.
Also any snack food that comes in a shiny red bag with a picture of triangular shaped corn chips with cheese seasoning sprinkled all over them would hardly be considered junk food......
OK, maybe that's stretching things a bit
I don't buy much "junk food" such as potato chips, Doritos, slim Jims......, but I do typically drink a lot of pop, not lately though for some reason. Usually 2-3 cans/day, lately maybe one, but instead I have citrus flavored ice tea, which would certainly fall into some of your opinions as junk food, too, what with all of its fructose. Sometimes I'll get on a white cheddar cheese-its binge because they're offered on special if you buy 4 or 5 boxes. I guess that's junk food. I'll have them, eat them, then won't buy anymore for months.
Hmmm, are Triscuits, in all their salty glory, junk food? What if you put a piece of swiss cheese and a slice of pepperoni on it and nuke it, is it still junk food then?
I eat so late at night that I don't sit there and munch junk food while I'm watching TV, but I usually drink pop and eat a candy bar (or two) every day. I guess I eat what I consider junk food in spurts.
