Food Dyes, Activity, and Learning

  • C. Keith Conners


We have not found conclusive evidence that improvements on the Feingold diet are related to an allergic response to the artificial colors, neither have we found any reliable evidence that children who eat artificial colors on the Feingold diet become worse in behavior. Although we found such an effect in our second challenge study, it was not repeated in our third challenge study. Our strongest evidence seemed to come from the sensitive measures of visual-motor tracking while the child was trying to perform under conditions of distraction. That effect seemed to be brief and transient, as if a drug had acted briefly and then diminished in activity. Since we no longer had the computerized tracking apparatus to investigate this question further, we decided to use alternative methods that would be sensitive indicators of attentiveness and activity.
