ADHD: Are these 8 food dyes to blame?

Do food dyes trigger hyperactivity? Some scientists say they do, at least in some children. And now the FDA has convened a panel to weigh the evidence linking these petroleum-based dyes to the behavioral disorder. The move could lead to warning labels on many foods kids love, including candy and breakfast cereals, though experts say it's unlikely the government will follow Europe's lead in banning the dyes.

Eight dyes are in the spotlight, according to the Center for Science in the Public Interest, which in 2008 petitioned the FDA to ban them. Keep reading to see all eight - and the foods that often contain them.

We've assembled the list with the help of CSPI and the Institute for Agriculture and Trade Policy.
