The likelihood of experiencing psychiatric distress and displaying violent behaviors may be on the high side in children and adolescents who love consuming junk foods.

This study explored the correlation between frequent ingestion of junk foods and the incidence of psychiatric distress and violent behavior in children and adolescents. The study population included 13,486 Iranian children and adolescents who were within the age bracket of 6-18 years. 

Researchers found out that children and adolescents at the top of the junk food intake ladder tend to have a high propensity to suffer from psychiatric distress and exhibit violent behaviors, such as bullying and physical fighting. This study came to the conclusion that "junk food consumption may increase the risk for psychiatric distress and violent behaviors in children and adolescents."
