Do BPS and BPF disrupt the cerebellum, the brain's balance and coordination center?
Yes. Lab studies show BPS and BPF mess with estrogen receptor and BMP2 signaling in the cerebellum.
What's actually in it
The cerebellum is the brain's balance and coordination center. It runs walking, fine motor skills, and timing. It's also full of estrogen receptors and BMP2 signaling, which guide cerebellum cell development. BPS and BPF are the replacement bisphenols in "BPA-free" plastics. They lock onto the same receptors that BPA does.
What the research says
A 2026 study in Toxicol Lett showed BPS and BPF disrupt cerebellum function through estrogen receptor and BMP2 signaling. A 2026 review in Mol Neurobiol pulled together studies on BPS and the brain. The picture matches BPA: oxidative stress, hormone disruption, and damage to brain cells.
Skip thermal-paper receipts. Use glass or stainless water bottles. For canned food, pick brands like Eden Foods, Wild Planet, or Native Forest that say "no BPA, BPS, or BPF." Reusable bottles for kids work best in steel (Pura Kiki, Klean Kanteen Kids) or silicone.
