Transcript for Soda and Possible Cancer Risk
A major headline about your health tonight, with a question mark for anyone who drinks sodas with that caramel color. A chemical that in some cases has been linked to cancer in mice. A new health warning tonight. And ABC's Dr. Richard Besser is here. Reporter: When you sip that soda, you may be drinking it. Caramel coloring, a common ingredient. But could some actually cause cancer? Consumer reports tested 110 sodas from California and New York. They found some had an ingredient in the coloring called 4-mei. They believe some of the levels they found were too high. At very high levels, it can cause tumors in mice. California requires a cancer warning on products that contain certain levels of the chemical. Consumers shouldn't have to be subjected to this unnecessary risk just to color food brown. Reporter: But while the fda today said they have been looking into this, they did make clear they believe sodas are safe to drink. The American beverage association disagreed with consumer reports' concerns, as did Pepsi, which pointed out that it even adheres to California's toughest-in-the-nation regulations. Saying -- all of our products are in full compliance with the law. Based on what we know right now, you would need to drink more than 1,000 cans of soda every day to take in as much of the chemical as the mice that got cancer. I'm not concerned. If you're looking for the labels with caramel color, you have a choice. But you're not entirely concerned yet? I'm not. Rich, thank you.
