The document discusses the childhood obesity epidemic in the United States. It notes that over the past 30 years, childhood obesity rates have doubled and tripled, with over 1/3 of children and adolescents being overweight or obese as of 2010. The primary cause identified is parents, as children typically share their parents' eating habits and foods consumed. To solve the epidemic, the document argues that parents must change their own dietary habits and receive better education on proper nutrition, as they directly influence their children's health.
