Should I worry about BPS in plastics making liver fibrosis worse?
Yes in animal studies. BPS triggers liver scarring through immune and stress pathways.
What's actually in it
Bisphenol S (BPS) replaced BPA in many plastics, receipts, and can liners. Marketing implies safer. The biology disagrees. The liver processes BPS, and the liver doesn't always do it cleanly.
What the research says
A 2026 study in Toxicol Appl Pharmacol showed that BPS promotes hepatic fibrosis through macrophage polarization and autophagy-driven activation of hepatic stellate cells. In plain words: BPS pushes immune cells to scar the liver. Scarring means less function over time.
Skip thermal-paper receipts. Choose canned foods labeled "no BPA, BPS, or BPF" or pick jars and pouches. Use stainless or glass water bottles. Move hot food into glass before reheating. Reusable bottles for kids are best in stainless steel, not BPA-free plastic that may use BPS.
