Coke and Pepsi have always been in competition with one another, but this time around, the prize could be saving customers' lives.
According to an environmental group out of California, Pepsi has not yet eliminated, nationwide, a caramel coloring in its sodas. The group believes the chemical which is created during the production of the coloring could cause cancer.
The chemical created is called "4-Me" and has been banned in both Coke and Pepsi products in California.
A test performed on Coke products across the country has proved that the coloring is no longer used. This elimination has left one request from the environmental group.
"Pepsi's been able to eliminate it in California. We're asking, why not in the rest of the country?" said Kathryn Alcantar who is a member of the Center for Environmental Health.
According to Pepsi, it will be free of the chemical completely by February of 2014.
Though this environmental group is suggesting an alarming health scare, the FDA says that these tests have only been done in rats, and that a person would have to drink around 1,000 cans a day to do any permanent damage.
