The Mars company, which manufactures M&Ms and other candies, stands by the safety of artificial dye, but is also trying to phase them out in favor of natural colors.
"We have absolute confidence in the safety of all the natural and artificial ingredients we use, as does the FDA and other leading food safety regulators globally," a Mars spokesperson said. "We are continuing to look at the use of natural colors, not just in the U.S., but around the world. Keep in mind, though, that this is not a process that can happen overnight."
While multiple studies have been done on artificial dyes, none have found an inextricable link between hyperactivity and food dye.
"I think the FDA review has been very compelling. It's been very comprehensive," said Sean Taylor, the scientific director of the International Association of Color Manufacturers. "And I think their conclusions are that there seems to be a small subset of the population that has a unique intolerance possibly to foods in general. There could be a small subset of consumers that have a unique intolerance to food additives, food colors, we really don't know at this point."
The Snedden family is not waiting for conclusive scientific study to banish manmade dye from their diets. Three years after removing the dye-filled foods, Snedden swears she will never go back.
"Everyone feels so much better and the mood at our house is so much better. No Dorito is worth trashing the atmosphere at my house," she said. "People have to decide, I don't have technicolor blue in my mouth because, well, that's poison."
