The /*FDA*/ is responding to a petition asking the government agency to ban eight dyes used in food.
Earlier studies have raised the possibility that some kids with behavioral issues like Attention-Deficit Disorder, or ADD, may have a unique intolerance to artificial food coloring.
An advocacy group wants the FDA to revoke approval for blue, green, orange, red and yellow dyes because of the results of those studies.
An advisory committee meets next week to discuss the issue.
