A New York mother wants changes made to the popular sweet treat M&Ms.
Renee Shutter said the coloring of the candy was making her son hyperactive. She said the M&M's made in the United States are mostly colored with dye from petroleum while the candies from Europe are made with dye from plants.
She's now building support with a Change.org petition calling for candy company Mars to remove artificial dyes.
"I thank God ever sing day that we figured this out. What breaks my heart is thinking about all these families that will never put those pieces together," Shutter said.
Mars says they are exploring the use of natural colorings. They've already obtained approval from the Food and Drug Administration for natural blue and green dyes.
The FDA does say that hyperactivity from artificial coloring can be an issue for some kids.
