The Coca-Cola Company, the world's largest beverage maker, is amending the recipe of several of its drinks following an online petition. The drinks manufacturer will remove a substance called brominated vegetable oil( BVO) from drinks like Powerade and Fanta. Do you have an idea what it is? BVO is a food additive that helps stop other ingredients from separating. It contains the chemical bromide, which is commonly used as a flame retardant. Coca-Cola spokesperson Josh Gold advised consumers that: "All of our beverages, including those with BVO, are safe and always have been, and comply with all regulations in the countries where they are sold. The safety and quality of our products is our highest priority."

In 1970, the USA's Food and Drug Administration removed BVO from its "generally recognized as safe" list but did not ban its use. The substance was the subject of a social media campaign to get it removed from drinks. An American teenager, Sarah Kavanagh, started a petition on the site Change.org. Does anyone know what she asked in her petition? She questioned why the ingredient was being used in what are supposed to be health drinks. More than 200,000 people signed the petition. Ms Kavanagh said: "It's really good to know that companies, especially big companies, are listening to consumers." She added: "I'm glad to know the Powerade sold at my school and consumed by people around the world will be a little bit healthier without BVO."
