Most American children would trash the healthy foreign meals because all they want is fast food.
Some of what you say may be true in a localized sense, granted. However, you aren’t trying to tell us that the crap shown for nutritious American lunch meals has value, are you? My experience as a long time father of two children and three grand daughters tells me visuals play an enormous part.
Lastly, there is one whopping big difference between “fast-food” these kids might see anywhere in American society and the sh!t these snaps of American Michelle Carte-du-jour represent. Don’t even try.
