After years of rivalry between Pepsi and Coke, they've found one thing to agree on. That one thing is the way the caramel coloring in their pop/soda is made.

They're doing it to avoid a new California law that requires a cancer warning label on drinks with a certain level of carcinogens in them.

These changes shouldn't affect the product taste or quality and there are no reasons for health concerns, according to the American Beverage Association.

A petition/complaint from the Center for Science in the Public Interest (the same people who railed on movie-theater popcorn and other guilty indulgences) was filed in February asking for a ban on ammonia-sulfite caramel coloring.

The FDA is reviewing the petition, but an FDA spokesperson said a consumer would have to drink more than 1,000 cans of soda a day to reach the doses that have shown links to cancer in rodents.
