Swedish Fish aren't technically an American junk food as they are created by a Swedish company. Unless of course you are just referring to the fact that they are consumed in America.
I am still trying to wrap my mind around the fact that candy is being called food in English. Food to me has always been what you eat at lunch and dinner, not the junk in between. Ergo junk food is burgers and chips, candy is too junk to be even called food.
I wouldn't say burgers are junk food. A grilled burger of grass-finished beef with healthy toppings is real food - I eat mine wrapped in lettuce rather than a bun. But I can't argue with you about the candy. It may fit the definition of "food" as consumable, but it is definitely not real food.
I'm not sure if they ever used the "eating them in bed" bit specifically, but a big part of their advertising was stating that Newtons were NOT cookies.
If it has caloric value, it's probably eaten by somebody.
they're not technically cookies" in a Fig Newtons commercial/ad? I could not think of anything besides Nilla Wafers.
