SUBJECT: ASPARTAME
Not a true/false call. Every claim is logged with its sources; read the exhibits below.
I just had Michael Mals in here. He was talking about how he got off Aspartame and how his brain fog just completely cleared up.
What the evidence says 01 / RECORD
Rogan relays a single secondhand anecdote that a former guest's "brain fog" cleared after stopping aspartame consumption, presenting an individual, unverified experience as though it demonstrates a causal effect. Major regulatory and scientific bodies have extensively reviewed aspartame's health effects: a July 2023 joint assessment by the WHO/IARC and the FAO/WHO Joint Expert Committee on Food Additives (JECFA) classified aspartame as "possibly carcinogenic" (IARC Group 2B) based on "limited evidence," while JECFA reaffirmed the existing acceptable daily intake of 40 mg/kg body weight, finding no other safety concerns at typical consumption levels. The U.S. FDA has stated it does not have safety concerns about aspartame under approved conditions of use and noted shortcomings in the studies IARC relied on. Neither body's review identifies reliable evidence that aspartame causes "brain fog" or that discontinuing it reverses cognitive symptoms. The claim as stated is an unsubstantiated personal anecdote rather than an evidence-based causal finding.
