A recent study by Purdue University scientists has purportedly concluded that the amounts of artificial food colors found in many popular U.S. foods are much higher than previously thought, and children—the target market for the most heavily dyed foods—could be consuming 100 to 200 mg of artificial color in a day, well over the 30 mg that has allegedly been shown to contribute to behavioral disorders such as attention deficit hyperactive disorder.
Although manufacturers are required to disclose whether a food contains artificial coloring, the law does not require that they disclose how much of each color is used, and, according to the study, the amounts of artificial coloring in foods has increased more than five-fold since 1950.
“In the 1970s and 1980s, many studies were conducted giving children 26 mg of a mixture of dyes,” said study author Laura Stevens. “Only a few children seemed to react to the dyes, so many doctors concluded that a dye-free diet was pointless. Later studies using larger doses showed that a much larger percentage of children reacted. But some researchers considered those doses unrealistically high. It is now clear that even the larger amounts may not have been high enough. The time is long past due for the FDA [U.S. Food and Drug Administration]to get dyes out of the food supply or for companies to do so voluntarily and promptly.” See FoxNews.com, May 21, 2014.
