Concern that synthetic food dyes may impact behavior in children prompted the California Office of Environmental Health Hazard Assessment (OEHHA) to review the research on both children and animals.
64% of the 25 challenge studies reviewed identified evidence of a positive association, and in 52% this association was statistically significant. Thus, they concluded that these studies support a relationship between food dye exposure and adverse behavioral outcomes in children.
QUOTE: “Together, the human clinical trials and animal toxicology literature support an association between synthetic food dyes and behavioral impacts in children.”
The authors conclude, also, that there is a need to re-evaluate the current acceptable daily intakes (ADI) amounts which are based on older studies that did not consider behavioral effects.
NOTE: I sent a collection of studies on food dyes and behavior to the OEHHA to help them in their investigation. I have added a cover page and posted this collection as a “book” on this blog. See it here:
