I gave an age range for a very specific reason: That's the age group this food pyramid was pushed hard on kids. I didn't know it changed because I was finishing gradeschool as the change happened.

You don't have to memorize and precisely follow it to have internalized generic things like "lots of carbs = good". They are supposed to be our bodies' main source of energy and there's really no way you can have too much (or so we were taught at the time).
