The documentary Super Size Me uses various codes and conventions to represent Americans as overweight and fast food-loving. It portrays the U.S. as the fattest country in the world through statistics and footage of real Americans. While it aims to show the negative health effects of fast food, the representation of Americans is biased. It also sympathetically depicts teenagers' struggles with obesity and fast food addiction. Experts are represented as credible sources confirming that fast food is unhealthy.
