When you hand your child a colorful snack or brightly packaged cereal, it might seem like harmless fun.
But a new study suggests those vibrant hues could be masking a far more serious issue.
According to research published in the Journal of the Academy of Nutrition and Dietetics, nearly 20 percent of packaged foods and drinks sold in the United States contain synthetic dyes, and a staggering 28 percent of those products are marketed specifically to children.
Researchers found that Red No. 40, in particular, appeared in 14 percent of all products examined, making it the most prevalent artificial dye in the American food supply.
Despite offering no nutritional value, these dyes are routinely added to make processed foods more visually appealing, often disguising low-quality or overly sugary ingredients.
The same study revealed that products containing synthetic dyes had, on average, 141 percent more sugar than those without.
Foods with dyes averaged 33.3 grams of sugar per 100 grams, compared to just 13.8 grams in dye-free items.
This correlation between artificial colors and high sugar content raises serious red flags, especially given the well-documented relationship between sugar and metabolic dysfunction in children.
According to UNC researcher Dr. Elizabeth Dunford, the lead author of the study, these chemical-laden foods are not only visually engineered for children but also chemically designed to increase cravings and overconsumption.
Multiple studies have linked synthetic food dyes to hyperactivity, allergic reactions, and even neurological changes in children.
In fact, one widely cited review by the California Office of Environmental Health Hazard Assessment concluded that certain artificial dyes may impact attention and behavior in susceptible children, even at levels currently allowed in the U.S.
The regulatory response, however, has lagged behind the science.
While Red Dye No. 3 has finally been banned by the FDA as of 2025, manufacturers have until 2027 to remove it from their products.
Other dyes like Yellow No. 5 and Blue No. 1 remain legal in food, despite research showing potential effects on the immune system, respiratory function, and brain development.
In contrast, many European countries require products containing synthetic dyes to carry warning labels about potential behavioral impacts.
Health Secretary Robert F. Kennedy Jr. has pledged to phase out these additives in the U.S., but no enforceable timeline has been announced.
That leaves parents and consumers to make informed decisions on their own.
While we wait for meaningful reform, there are steps families can take to reduce exposure.
Avoid foods labeled with “FD\&C” followed by a number, a common designation for artificial dyes.
Opt for organic products, which prohibit synthetic dyes entirely.
When possible, cook meals from scratch using whole ingredients, limiting the potential for hidden additives.
Finally, support the body’s detox systems with antioxidant-rich foods like berries, leafy greens, and cruciferous vegetables.
The widespread use of synthetic dyes in products marketed to children is not just a food safety concern—it’s a public health crisis in plain sight.
These additives are unnecessary, potentially harmful, and disproportionately present in the diets of vulnerable populations.
Lasting change will require stronger government oversight, greater corporate accountability, and continued consumer demand for transparency.
Until then, awareness is our most powerful tool.

The bright colors on the shelf may catch the eye—but it’s what they hide that truly deserves attention.
