Aspartame is an FDA-approved food additive for use as a general-purpose sweetener in the United States. JECFA has evaluated aspartame and set an acceptable daily intake. EFSA has also evaluated aspartame and concluded it is safe at current intake levels. In 2023, the International Agency for Research on Cancer (IARC) classified aspartame as possibly carcinogenic to humans (Group 2B), while JECFA maintained its existing acceptable daily intake, stating there was no convincing evidence of harm at typical consumption levels.
