CNN — They're some of America's favorite little treats. So why is there a push to make a change to M&M's? Some parents say the coloring makes their kids hyperactive. Now a petition has been launched to make the manufacturer to adjust how the candy gets its color, which varies in different parts of the world, Elizabeth Cohen reports.
The colors of M&M's are so iconic , they're the candy coated of their own TV commercials.
So what gives the real M&M's their colors? Well, that depends on which country you're in.
We bought these M&M's locally. Yellow 6, yellow 5, red 40 all names for artificial food coloring, derived from petroleum, but these M&M's come from England and their colors come mostly from plants.
Renee Shutters, Mom, "I just think it's not fair that our country is the one getting the artificial dyes while Europe is getting natural dyes."
Renee Shutters says her son Trenton used to suffer regular meltdowns, but then his behavior improved remarkably when she took artificial dyes out of his diet, including, no more M&M's.
Now she's building support for her cause more than 140,000 people have signed her change.org petition, calling on the candy company Mars to remove artificial food coloring from M&M's, and she might have a chance.
In November, under similar pressure from parents, Kraft took out the iconic artificial yellow coloring contained in some of its Mac and Cheese products and swapped it for a natural coloring.
Mars tells CNN in a statement they are exploring the use of natural colorings. They've already obtained approval from the food and drug administration for a natural blue and green dye.
Changing to natural colors won't happen overnight, the company warns, and they say they have absolute confidence in all their ingredients.
It's debatable whether artificial coloring really do cause hyperactivity, the FDA says for some kids, they may be an issue, but Renee Shutters is convinced, "I thank God every single day that we figured this out. What breaks my heart is thinking about all these families that will never put those pieces together."
