The World Health Organization on Thursday classified the soda sweetener aspartame as a possible carcinogen, but said it is safe for people to consume within the recommended daily limit.
Aspartame is used in Diet Coke, Pepsi Zero Sugar and other diet sodas, as well as some chewing gum and various Snapple drinks as a substitute for sugar.
More research is needed to determine whether consumption of the artificial sweetener can actually lead to cancer, she said.
"Aspartame is one of the most studied food additives in the human food supply," the spokesperson said.
"FDA scientists do not have safety concerns when aspartame is used under the approved conditions."
