Carcinogens found in regular and diet Coke and Pepsi, consumer group says

Coca-Cola, Pepsi-Cola, Diet Coke, and Diet Pepsi contain high levels of 4-methylimidazole or 4-MI, a known animal carcinogen, a new chemical analyses has found.

The carcinogen forms when ammonia or ammonia and sulfites are used to manufacture the “caramel coloring” that gives these sodas their brown colors, according to the Center for Science in the Public Interest, the consumer advocacy group that commissioned the tests.

The center petitioned the U.S. Food and Drug Administration to ban ammonia-sulfite caramel coloring in February 2011.

This week, the center again asked the FDA to revoke its authorization for caramel colorings that contain 4-MI, and to change the name of the additive to “ammonia-sulfite process caramel coloring” or “chemically modified caramel coloring” for labeling purposes.

“Coke and Pepsi, with the acquiescence of the FDA, are needlessly exposing millions of Americans to a chemical that causes cancer,” Michael F. Jacobson, center executive director, said in a statement.

“The coloring is completely cosmetic, adding nothing to the flavor of the product,” Jacobson said. “If companies can make brown food coloring that is carcinogen-free, the industry should use that. And industry seems to be moving in that direction. Otherwise, the FDA needs to protect consumers from this risk by banning the coloring.”

The center collected samples of Coca-Cola, Pepsi-Cola, Diet Coke, Diet Pepsi, Dr Pepper, Diet Dr Pepper, and Whole Foods 365 Cola from Washington, D.C.-area stores:

• Pepsi’s products had 145 to 153 micrograms (mcg) of 4-MI in two 12-ounce cans.
• Regular Coca-Cola had 142 mcg per 12 ounces in one sample and 146 mcg in another.
• Diet Coke had 103 mcg per 12 ounces in one sample and 113 mcg in another.

California has a 29-microgram benchmark for 4-MI. Levels above that in a serving of food or beverage may be required to bear a warning notice. Based on California’s risk model, the center estimates that the 4-MI in the Coke and Pepsi products tested is causing about 15,000 cancers in the U.S. population.

While federal law bans food additives that cause any number of cancers, the FDA has an exception for contaminants of food additives. It tolerates a lifetime risk of one cancer in one million people.

Three of four samples of Dr Pepper or Diet Dr Pepper that center tested had low levels of 4-MI, with about 10 mcg per 12 ounces. But even those levels pose a cancer risk of seven in one million – seven times greater than what the FDA allows, according to the center. The lower levels in those three samples indicate that it’s possible to lower, if not eliminate, the amount of 4-MI.

Pepsi told the center that it has switched to a coloring in California that contains much less 4-MI and plans to do the same in the rest of the country, Jacobson said.

When most people see “caramel coloring” on food labels, they likely assume the ingredient is similar to what you might get by gently melting sugar in a saucepan, he said.

“The reality is quite different,” Jacobson added. “Colorings made with the ammonia or ammonia-sulfite process contain carcinogens and don’t belong in the food supply. In any event, they shouldn’t be obscured by such an innocuous-sounding name as ‘caramel coloring.’”

While the test results are troubling, the center says soda drinkers should be much more concerned about the high-fructose corn syrup or other sugars used in soft drinks. Soda drinkers are much more likely than non-soda drinkers to develop weight gain, obesity, diabetes, and other health problems.

I really feel the pain of peoples who are addicted to coke like me, we actually don't know whether it will cause a disease to us or not.
