Some common chemicals found in many products like Halloween candy have many parents concerned.
Researchers say there may be a link between dyes and behavior problems in kids.
The Food and Drug Administration has been looking into these dyes for years.
Health officials said the chemicals are not toxic and don’t cause hyperactivity in children.
However, the agency found the chemicals, the artificial coloring, may exacerbate issues in children with ADHD and other behavioral conditions.
