I didn't know that until I read about a lawsuit that has been brought against soft-drink manufacturers in New York, including PepsiCo.
The lawsuit alleges that the soft-drink makers are selling drinks, such as Diet Wild Cherry Pepsi, which are made with ingredients that can form a cancer-causing agent known as benzene.
Benzene can form in soft drinks containing vitamin C (ascorbic acid) and sodium benzoate or potassium benzoate. Heat or light exposure can trigger a reaction that forms benzene in beverages.
Coca Cola was formerly involved in the lawsuit, but they settled with the plaintiffs earlier this month.
PepsiCo claim the lawsuit is without merit. However, a federal court has ruled that the case will move forward.
It will be interesting to see what happens. I'll watch this space. In the meantime, soft drink lovers may want to reduce their consumption of the beverages to safeguard their health.
