Lack of behavioral effects from Feingold diet violations

Area of Science:

• Pediatric Nutrition
• Behavioral Science
• Dietary Interventions

Background:

• The Feingold diet, which excludes artificial colors and flavors, is popularly believed to improve hyperactive behavior in children.
• Parental reports often suggest positive outcomes, but objective scientific validation is crucial.

Purpose of the Study:

• To objectively evaluate the efficacy of the Feingold diet in managing hyperactive behavior in children.
• To compare objective measures with parental reports regarding the diet's effects.

Main Methods:

• A double-blind, cross-over study design was employed.
• Included children whose parents reported significant improvement with the Feingold diet and negative effects from dietary violations.
• Evaluated 14 objective measures to assess behavioral changes during diet infraction and noninfraction periods.

Main Results:

• No statistically significant differences were found in objective measures between the diet infraction and noninfraction conditions.
• Objective findings contradicted parental reports of the Feingold diet's positive impact on hyperactivity.

Conclusions:

• The study questions the efficacy of the Feingold diet for improving hyperactive behavior in children.
• Highlights the need to validate parental reports with objective data and consider potential negative effects of strict dietary adherence.
