The debate around Food Dyes and their potential impact on children’s behavior, particularly hyperactivity, has been ongoing for years. While some studies suggest a link, the scientific community is still far from reaching a consensus. The conversation gained significant traction with studies like the Southampton study, which raised concerns about synthetic food dyes.
These randomized, double-blind studies appeared quite compelling to some researchers. However, critics pointed out that the food colorings and the preservative were consumed together in a drink mixture, not in isolation. This mixing of substances created uncertainty about whether the dyes alone were responsible for the observed effects.
Despite these doubts, the findings were impactful enough to influence policy changes. The British government urged food manufacturers to reduce the use of artificial dyes. Furthermore, the European Parliament mandated warning labels on food products containing certain dyes, stating they “may have an adverse effect on activity and attention in children.”

FDA’s Stance on Food Dyes
In 2011, the FDA’s food advisory committee reviewed research, including the Southampton study, during public hearings. The purpose was to determine if food dyes were causally linked to hyperactivity. Ultimately, the committee concluded that there was no conclusive causal link and therefore, no need for mandatory warning labels similar to those in the EU.
Dr. Arnold, an expert who testified before the FDA committee, clarified the nuances of the findings. “If the question had been, ‘Is there evidence food dyes affect behavior in children?,’ I think it might have gone more in an affirmative direction,” he stated. He emphasized the distinction between demonstrating a direct cause of a disorder versus acknowledging that food dyes might influence behavior. The FDA maintains its position that artificial food dyes are “safe” for consumption under current regulations.
The Lingering Question: Consensus or Controversy?
Since 2011, numerous reviews and meta-analyses have investigated the topic further. Some have indicated that eliminating food dyes from the diet can have positive behavioral effects, particularly in some children diagnosed with ADHD. However, experts like Dr. Arnold emphasize that significant gaps in knowledge remain, necessitating more robust and refined research. Limitations in previous studies include the use of unrealistically low doses of food dyes and the combined study of dyes with other additives, making it difficult to isolate the effects of food dye alone.
The American Academy of Pediatrics has not taken an official stance on artificial food colors. According to Dr. Lowry, this is because the evidence is still not definitive enough to warrant a clear recommendation. The existing body of research presents a mixed picture, with some studies suggesting an effect, others finding no effect, and many calling for further investigation to reach a more conclusive understanding.
Practical Advice: How Concerned Should Parents Be?
Both Dr. Arnold and Dr. Lowry agree, based on their clinical experience, that food dyes can have a behavioral impact on some children, though not universally. Dr. Arnold notes, “Clinically, I’ve noticed there are a lot of kids who seem to do better without the dyes. They seem to aggravate pre-existing problems.” Dr. Lowry echoes this, stating, “There are families who swear by not eating red dye number whatever. They take it out and their child’s behavior improves.”
Dr. Lowry advises parents of children with behavioral concerns to stay informed and proactive. “If you feel that standard medicine isn’t working, then look at the diet. Trying to remove these additives as much as possible can be helpful.” Dr. Arnold further suggests that reducing exposure to synthetic food dyes is a prudent step for all children, regardless of an ADHD diagnosis. He underscores that these dyes are purely for aesthetic purposes, enhancing product appearance without adding nutritional value or taste.
Dr. Arnold highlights the consumer’s power in this matter. “Companies want people to buy and eat more food, and who needs to eat more food in an obesity epidemic?” he questions. He concludes with a call to action: “The consumer actually controls this. If you don’t buy things that have artificial colors, they’ll stop making those products.” By making informed choices, consumers can collectively influence the food industry’s reliance on artificial food dyes.
