Read more here about the American non-profit organization trying to lobby the FDA to ban the use of these ingredients.
So far the only thing we can do is stop buying products containing these ingredients, (which by the way, are made of coal tar and petroleum YUMMY!). The colorings CSPI seeks to ban are: Yellow 5, Yellow 6, Red 3, Red 40, Blue 1, Blue 2, Green 3, and Orange B. Even if you don't have children, the idea of putting children at risk should be enough to start limiting your own intake of these products.
Some well known products that contain these ingredients are cereal, soft drinks, candies including Skittles and Starburst (sorry Kristeen! One more reason to abstain I guess.) and basically anything marketed to children. Great right!
For years people figured it was the sugar in these products causing their children to act up, apparently there is more to the story.
