Why Butylated Hydroxytoluene is flagged
BHT has complex, bidirectional carcinogenicity data — some NTP bioassays found liver tumors in female mice at high doses, while other studies suggested BHT might inhibit cancer initiation. IARC has not formally classified BHT due to conflicting evidence. A 2017 study linked BHT to thyroid hormone disruption in female rats. The American Academy of Pediatrics (2018) recommended reducing synthetic preservative exposure including BHT in children. Kellogg's uses vitamin E in European versions of cereals that contain BHT in US versions — a commercially meaningful substitution.
