Which artificial sweetener was linked to bladder cancer?
In the early 1970s, studies investigating artificial sweetener linked to bladder cancer showed a possible connection in lab rats between the disease and saccharin. However, further research found that these results applied only to rats, especially male ones, and that the animals had to consume high doses of saccharin for the cancer to occur. No studies have shown any consistent evidence that saccharin causes bladder cancer in people.
