Kids have been bringing brown bag lunches to school for at least the last hundred years, and even though the overall contents have stayed the same the individual parts have changed dramatically.
A brown bag lunch typically includes a drink, a piece of fruit, a sandwich and a sweet snack, contents which have been a constant since the early 1900s.
However, the kids of today would throw a fit if they found a jar of warm milk and a radish sandwich in their bag, which was a fairly standard lunch for kids in the early 1900s.
Bon Appétit subjected a bunch of youngsters to the brown bag lunches of yesteryear, starting with that nasty radish sandwich and ending with the pre-packaged Lunchables craze of the 90s.
