The World Health Organization’s (WHO) International Agency for Research on Cancer (IARC) recently concluded that the popular artificial sweetener aspartame, widely used in foods and diet drinks, is “possibly carcinogenic to humans,” an alarming conclusion because aspartame is used in thousands of low-calorie products. However, another WHO organization, the Joint Expert Committee on Food Additives (JECFA), concluded that it is safe to consume aspartame. Can we make sense of the conflicting conclusions?
