Texas A&M Links 1-Third-of-Global Plastic to Fatty Liver Disease

Summary
Polyethylene microplastics raised markers of fatty liver disease in a Texas A&M study, with liver damage worsening further when exposure was paired with a high-fat, high-fructose, high-cholesterol diet.
About 25% of people worldwide have fatty liver disease, and the finding is notable because polyethylene—used in food wrappers, containers and cup linings—has long been treated as relatively biologically inert.
Spatial transcriptomics mapped where liver injury occurred and pointed to PPAR-alpha, which regulates fat metabolism, and the tissue-repair gene ANXA2 as key pathways in the microplastic response.
Polyethylene makes up roughly one-third of global plastic production, and the researchers said the work opens questions about fibrosis risk, possible treatments targeting PPAR-alpha and whether other microplastics harm the liver similarly.
