>> reporter: his parents say trenton used to be a problem child with regular meltdowns and fits.

>> i start throwing tantrums. no matter what it is.

>> reporter: that's when his mom read about a possible link between artificial dyes in foods and behavior in some kids.

>> i'm like food coloring ? you mean food coloring could cause this? i never would have expected that.

>> reporter: so she stopped giving him food with those dyes and says the results, while unscientific were incredible. within days trenton was a different kid.

>> we saw amazing results at school. we saw amazing results in his attitude. he was happy. no more meltdowns at all. it was awesome.

>> reporter: the fda has been looking into these dyes for years and found while they're not toxic and don't cause hyperactivity in kids, the fda concluded for certain susceptible children with adhd and other problem behaviors the data suggests their condition maybe exacerbated by artificial food colors because of a unique sensitivity.

>> there's thousands of foods making it difficult for people to avoid them.

>> reporter: michael jacobson runs a watchdog group that says these dyes come in everything from candy to fruit drinks to waffles and mac and cheese. even in foods that aren't colorful like marshmallows and white frosting.

>> in europe, they have to put a warning label on the product. what have the companies done?

>> gotten rid of the dyes and replaced them with natural colorings.

>> why don't they do it here?

>> because of profits. dyes are cheaper than natural coloring.

>> money.

>> it's about money.

>> reporter: the makers of m&m, mars and gma said the overwhelming majority of studies confirm the safeties of the studies. they're always reviewing new studies for the safest possible product and mars is continuing to explore the use of natural colors but they still don't use natural colors in m&ms here.

>> dear ceo of mars incorporated --

>> reporter: so trenton and his mom are petitioning mars to take the artificial dyes out.

>> they changed. it's that big of a deal. it's that big of a deal. i just felt so good.
