A common theme in JapanseJapanese cartoons (manga and anime) is having a protagonist that has a big appetite and the ability to eat a lot. We see examples of this in Dragonball and One Piece.
Historically, manga was heavily influenced by Western culture. Yet it's uncommon to see American cartoon characters stuff their faces with food and enjoy it as much. The only example I can think of is Jughead from Archie Comics.
My questions are, why do manga characters love to eat so much food and where does it originate from? Is there something specific to Japanese culture and food?
