Aspartame, a sweetener found in Diet Coke and other sugar-free products, has been found to be possibly carcinogenic in high doses.
Two groups linked to the World Health Organisation (WHO) released a long-awaited report on Thursday which found that the product, also found in Extra chewing gum, is a potential hazard. But a person would need to drink the equivalent of around nine to 14 cans per day to be at risk.
