Some studies link the popular soda sweetener to higher cancer risk, but the links are weak and questions remain
On 29 June 2023, the soda industry was bracing for a fresh wave of controversy. A media leak had suggested that a research arm of the World Health Organization (WHO), which had been reviewing the artificial sweetener aspartame, was planning to classify the addictive as possibly cancer-causing.
The sweetener – included in candy, soft drinks such as Diet Coke and Diet Pepsi, and common items such as toothpaste – has long been dogged by questions about potential health risks. And such a determination could disrupt consumers’ spending and billions in annual sales.
