Several studies have shown correlations between exposure to lead and other toxic metals and such factors as learning disabilities and extremely aggressive behavior. Studies of incarcerated juvenile offenders have also shown a connection between the consumption of refined sugar and antisocial behavior.

The research has not yet suggested simple nutritional cures to problem behavior, but it indicates the possibility of using the new information in helping schools address the problems of violence and disorder. 35 reference notes.
