Do Food Dyes Make Kids Hyperactive?

The video discusses the effects of synthetic food dyes on children's behavior, referencing a 2021 report by California's Office of Environmental Health Hazard Assessment. The report suggests a potential link between food dyes and behavioral issues, but the data is inconsistent. Media interpretations often highlight studies showing significant associations, but many studies do not support this. The analysis reveals that only a few studies show large effect sizes, and many have methodological issues. Parent-reported effects are often larger than those measured objectively. Overall, the evidence is inconclusive, and while removing dyes may not harm, their behavioral impact is not alarming.
