Can BPA replacements like BPS raise liver-scarring concerns?
A 2026 lab and animal study found that bisphenol S, a BPA replacement, pushed liver-fibrosis pathways. This is not proof that BPA food containers cause tissue scarring in people.
Short answer
Do not read this as proof that one plastic container causes liver scarring. The paper on this page studied bisphenol S (BPS), not BPA. BPS is often used as a BPA replacement.
A 2026 Toxicology and Applied Pharmacology study tested BPS in zebrafish, mouse immune cells, and human hepatic stellate cells. BPS pushed liver-fibrosis pathways through macrophage changes and autophagy in those models.
What this means at home
This is early science. It does not prove that BPA food containers cause tissue scarring in people. It does show why BPA replacements deserve caution too.
If you want to lower bisphenol food contact, focus on heat and storage. Use glass for leftovers. Let hot food cool before it touches plastic. Choose fewer canned foods when that is easy.
Why glass storage fits
A 2019 Advances in Nutrition review found that food processing and packaging are major exposure routes for phthalates and bisphenols in pregnancy. It also found canned food intake was linked with higher urinary BPA.
Glass storage does not treat liver disease. It just reduces one common food-contact route.

What to use instead
Use glass storage for leftovers and warm foods. It lowers plastic food contact without claiming to treat liver scarring.
