The Center for Science in the Public Interest (CSPI) has petitioned the FDA to ban the artificial food dyes Yellow 5, Yellow 6, Red 3, Red 40, Blue 1, Blue 2, Green 3, and Orange B because they may cause hyperactivity and other behavioral problems in some children. You can see a CBS Evening News segment on this topic here.
Synthetic food dyes have been controversial for decades, but not until recently had any studies shown adverse effects. Information on three recent studies on food dyes and behavior are at available here on CSPI’s website.
