A new study out of Purdue University shows that the dye found in foods many kids eat could impact their behavior.
The Center for Science in the Public Interest reported the cereal, candy and drinks kids consume every day have higher levels of the dyes than the levels shown in trials to impair their behavior.
The study shows Trix has more than 36 milligrams of the chemicals -- Yellow 6, Blue 1 and Red 40. Cap'n Crunch's Oops! All Berries topped the list with 41 mg.
Kids lunch and dinner staple, Kraft Macaroni & Cheese, has 17.6 mg of artificial dyes per serving.
Food isn't the only source of the chemicals.
A Clinical Pediatrics study published last year found one of the largest sources of artificial dyes is what people drink.
In an 8-ounce serving, Kool-Aid Burst Cherry has 52.3 mg of artificial dyes.
Trials have shown that some children can be affected by up to 35 mg of the dyes. The amount needed to trigger a reaction in the most sensitive child is not known.
In 2011, the Food and Drug Administration examined the claims that dyes along with other ingredients may cause behavior problems in some kids.
Kraft has removed dyes in some of its kid-orientated products, but not its most popular one. Other companies have followed suit.
