An online petition made the Coca-Cola Company change its recipe for several drinks. The world's largest drinks maker will remove a substance called brominated vegetable oil (BVO) from drinks like Powerade. BVO is a food additive. It contains the chemical bromide, which is used in products to prevent fires. A Coca-Cola spokesman said: "All of our beverages, including those with BVO, are safe… .The safety and quality of our products is our highest priority."

The U.S. government removed BVO from its "generally recognised as safe" list in 1970. A few months ago, an American teenager started a petition to get BVO removed from drinks. She asked why it was put in health drinks. Over 200,000 people signed the petition. The teen said: "It's really good to know that companies… are listening to consumers." She added she was glad that drinks around the world would "be a little bit healthier without BVO".
