Insights
This study found no evidence that tartrazine or benzoic acid cause behavioral issues in children with suspected sensitivities. Double-blind challenges confirmed that these food additives did not trigger adverse reactions in the tested pediatric population.
Area of Science:
- Pediatric Allergy and Immunology
- Nutritional Science
- Behavioral Pediatrics
Background:
- Consumer concerns link food additives like tartrazine and benzoic acid to adverse behavioral effects in children.
- Previous anecdotal reports suggest a connection between these additives and immediate behavioral changes.
- Objective scientific verification is needed to address widespread beliefs about additive-induced behavioral issues.
Purpose of the Study:
- To objectively assess the behavioral impact of tartrazine and benzoic acid in children with a history of suspected adverse reactions.
- To determine if double-blind challenges can confirm or refute parent-reported behavioral sensitivities to specific food additives.
- To provide evidence-based information to prevent overdiagnosis of food additive intolerance.
Main Methods:
- Conducted double-blind, placebo-controlled challenges with tartrazine and benzoic acid in 24 children (ages 1.6-12.4 years).
- Patients had a documented history of adverse behavioral reactions to these additives and adhered to a strict avoidance diet.
- Behavioral changes were monitored by parents and nursing staff following administration of placebo and active substances.
Main Results:
- No statistically significant behavioral changes were observed in any patient after administration of either placebo or the active substances (tartrazine, benzoic acid).
- Parents and nursing staff did not report any adverse behavioral reactions during the double-blind challenges.
- Twenty-two out of 24 children tolerated a normal diet without issues post-challenge, indicating no confirmed sensitivity.
Conclusions:
- The study found no objective evidence to support a causal link between tartrazine/benzoic acid and immediate behavioral adverse reactions in the studied pediatric group.
- Results challenge the popular belief that these common food additives are responsible for behavioral problems in sensitive children.
- Emphasizes the need for rigorous, objective testing to avoid misdiagnosis and unnecessary dietary restrictions.
Abstract:
Double blind challenges with tartrazine and benzoic acid were performed in hospital in 24 children whose parents gave a definite history of a purely behavioural immediate adverse reaction to one of these substances. The patients, whose ages ranged from 1.6 to 12.4 years, were on a diet that avoided these items, and in all there was a clear history that any lapse of the diet caused an obvious adverse behavioural reaction within two hours. In no patient was any change in behaviour noted either by the parents or the nursing staff after the administration of placebo or active substances. Twenty two patients returned to a normal diet without problems, but the parents of two children insisted on continuing the diet. While popular belief has it that additives may have harmful behavioural effects, objective verification is required to prevent overdiagnosis.
