Coke, Pepsi are changing their formulation to avoid cancer warning

In response to accusation that an ingredient called 4-methylimidazole (4-MI), a coloring agent, Coca-Cola Co. and PepsiCo Inc. are changing the way they make the caramel coloring used in their soft drinks. In 2011, 4-MI was added to the list of known carcinogens (substance that can cause cancer) by authorities in California. In fact, the caramel color of soft drinks that we are all familiar with, is not sugar melted in a pan. it's a coloring made with ammonia that can be toxic in high amounts. However, the FDA and the American Beverage Association (ABA) insist the drinks are safe.

To comply with the law in California and avoid having to put a carcinogen label on all their caramel colored drinks sold in the states, Pepsi and Coke say they have begun to change the formulation by lowering levels of 4-MI. This change will later be implemented across the U.S
