The functional relationship between artificial food colors and hyperactivity.

T L Rose

    Journal of Applied Behavior Analysis
    |January 1, 1978
    PubMed
    Summary

    Artificial food colors may worsen hyperactivity in children. This study found a direct link between consuming artificial food colors and increased hyperactive behaviors, with no placebo effect observed.

    Area of Science:

    • Behavioral Psychology
    • Pediatric Nutrition
    • Neurodevelopmental Disorders

    Background:

    • Hyperactive behavior syndrome is a concern in pediatric health.
    • Dietary interventions, such as the Feingold K-P diet, are explored for managing behavioral symptoms.
    • The role of artificial food colors (AFCs) in behavior remains a subject of investigation.

    Purpose of the Study:

    • To experimentally investigate the functional relationship between AFC ingestion and hyperactive behaviors.
    • To analyze placebo and challenge phases in a controlled setting.
    • To assess the impact of AFCs on specific behavioral indicators.

    Main Methods:

    • Employed a modified BAB design with double-blind conditions.
    • Studied two eight-year-old females adhering to the Feingold K-P diet for over 11 months.
    • Utilized trained observers to record Out of Seat, On Task, and Physically Aggressive behaviors in a natural classroom environment.

    Main Results:

    • Confirmed a functional relationship between AFC ingestion and increased frequency/duration of hyperactive behaviors.
    • Demonstrated the absence of a placebo effect from AFC challenges.
    • Observed differential sensitivity of measured behaviors to AFC challenge effects.

    Conclusions:

    • Artificial food colors can elicit and exacerbate hyperactive behaviors in susceptible children.
    • The study provides evidence against a placebo response to AFCs in this context.
    • Specific behavioral measures show varying degrees of responsiveness to AFC challenges, highlighting the complexity of the AFC-behavior relationship.
