Can BPA-free products still affect liver health?
BPA-free plastic is not automatically a lower-concern choice. This study found BPS promoted liver fibrosis pathways in lab and zebrafish models, so repeated food contact with BPA-free plastic is worth reducing.
What the study looked at
A 2026 Toxicology and Applied Pharmacology study looked at bisphenol S, also called BPS. BPS is a common replacement for BPA in some products labeled BPA-free.
The study used zebrafish, mouse immune cells, and human hepatic stellate cells. These are lab models, not a human trial.
What the study found
BPS promoted liver fibrosis pathways in 2 ways. It shifted macrophage activity in an inflammatory setting, which then activated liver stellate cells. It also directly activated liver stellate cells through autophagy-related changes.
The authors tied these changes to the progression from fatty liver inflammation toward liver fibrosis. That does not prove one BPA-free bottle causes liver damage in people. It does show that BPS deserves caution.
What parents can do
Start with repeated food contact. Do not heat food in BPA-free plastic. Move leftovers into glass storage when you can. Use glass or stainless steel for food and drink when those options fit the job.
Bottom line
BPS is not a free pass just because a product says BPA-free. Glass food storage is a simple swap that reduces repeat contact with BPA-replacement plastics.
