The debate around food colorings and their impact on children’s behavior, particularly hyperactivity, has been a topic of discussion for years. While some studies have suggested a link, especially concerning mixtures of dyes and preservatives, the issue remains complex and not fully resolved. This article delves into the ongoing discussion surrounding food dyes, with a particular focus on Red Food Coloring, and what parents should consider.
The Studies That Sparked Concern About Food Dyes
Early randomized, double-blind studies brought attention to the potential connection between artificial food colorings and hyperactivity in children. These studies seemed convincing to some, suggesting that certain food dyes could contribute to behavioral changes. However, critics pointed out that these studies often tested mixtures of food colorings and preservatives together in a single drink. This raised questions about whether the effects were due to the dyes themselves, the preservatives, or the combination of both. This lack of isolation of individual components created some doubt about the definitive role of food colorings alone.

This initial research was significant enough to influence policy changes in some regions. The British government, for example, recommended that food companies reduce their use of synthetic dyes. Furthermore, the European Parliament mandated warning labels on food products containing dyes, stating that these ingredients “may have an adverse effect on activity and attention in children.” This precautionary labeling reflects a concern about the potential impact of food dyes on young consumers.
FDA’s Stance on Food Colorings: “Safe”
Despite the concerns and actions taken in Europe, the U.S. Food and Drug Administration (FDA) has maintained a different perspective. In 2011, the FDA’s food advisory committee reviewed research, including the Southampton study mentioned earlier, during public hearings focused on whether food dyes cause hyperactivity. The committee ultimately concluded that there was no established causal link between food dyes and hyperactivity. Consequently, the FDA did not implement warning labels similar to those required in the European Union.
According to Dr. Arnold, an expert who testified before the FDA committee, the subtle difference in the question being asked may have influenced the outcome. He suggests that if the question had been “Is there evidence food dyes affect behavior in children?”, the conclusion might have leaned more towards acknowledging an effect. Distinguishing between “causing a disorder” and “affecting behavior” is crucial. The FDA’s current position is that artificial food dyes, including red food coloring and others, are considered “safe” for consumption under current regulations.
The Ongoing Debate and Lack of Consensus
Since 2011, numerous reviews and meta-analyses have further investigated the effects of food dyes. Some of these studies have indicated that removing food dyes from the diet can have a positive impact on the behavior of some children diagnosed with ADHD (Attention-Deficit/Hyperactivity Disorder). However, experts like Dr. Arnold emphasize that significant uncertainties and areas for further, more rigorous research remain. Limitations in previous studies include the use of unrealistically low doses of food dyes and the practice of studying dyes and other additives as combined groups rather than individually.
The American Academy of Pediatrics also reflects this uncertainty, holding no official position on artificial food colors. This is because the existing evidence is not considered conclusive enough to warrant a definitive recommendation. As Dr. Lowry notes, the research landscape presents a mixed picture with studies showing varying results: some indicate an effect, others show no effect, and many call for more comprehensive research. This lack of consistent findings highlights the complexity of the issue and the need for continued investigation.
Practical Advice for Parents Concerned About Red Food Coloring and Other Dyes
While scientific consensus remains elusive, healthcare professionals like Dr. Arnold and Dr. Lowry acknowledge observing the impact of food dyes on children’s behavior in their clinical practices. They note that while not every child is affected, some children do seem to exhibit behavioral improvements when artificial food dyes are removed from their diet.
Dr. Arnold states, “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 anecdotal evidence, mentioning families who have seen positive changes in their children’s behavior simply by eliminating red dye and other artificial colors.
For parents of children with behavioral concerns, Dr. Lowry advises staying informed and considering dietary factors. “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 sensible approach for all children, regardless of an ADHD diagnosis. He points out that these dyes are purely for cosmetic purposes, enhancing visual appeal without adding nutritional value or flavor.
Ultimately, the choice lies with consumers. As Dr. Arnold concludes, “If you don’t buy things that have artificial colors, they’ll stop making those products.” Parents who are concerned about red food coloring and other artificial dyes have the power to influence the market by making informed purchasing decisions and opting for products that minimize or eliminate these additives.
