Franz Kafka's the Metamorphosis is about a man named Gregor who turned into a cockroach. This book uses symbols such as a picture in his room, doors and windows and food to show how Gregor's family dehumanizes him over many months.
Food is a great symbol of Gregor’s death . Food symbolizes how his family treats him after he turns into a cockroach. When Gregor first turns into a cockroach, food symbolizes how his sister cares for him unlike the rest of his family. His father beats him and both his parents lock him in his room. No one engages with him except his sister who brings him bread and milk, his favorite food but because he's a cockroach, he doesn't like it so his sister starts to bring him old rotten food instead.
