Will diet soda, yogurt, and cereal disappear from stores?
“the World Health Organization’s International Agency for Research on Cancer (IARC) declared aspartame as “possibly carcinogenic.” Another WHO committee, the Joint FAO/WHO Expert Committee on Food Additives (JECFA), independently assessed the ingredient, too, but maintained its existing recommendation — suggesting not that people cut the substance entirely out of their diets but that they limit their daily aspartame consumption to about 40 mg per kilogram (or about 2.2 pounds) of body weight. Diet soda contains about 200 mg of aspartame per 12-ounce can. By that measure, an adult weighing 60 kg, or roughly 132 pounds, would need to drink about 12 cans of diet soda a day to exceed the JECFA’s recommendation, assuming they had nothing else containing aspartame.
Making matters more confounding, the Food and Drug Administration had yet another take. It told Vox in an email that it had reviewed the information used in WHO’s assessment and “identified significant shortcomings” in the studies the agency relied on. “Aspartame is one of the most studied food additives in the human food supply,” the agency added.”
