Common Food Packaging Plastic May Contribute to Fatty Liver Disease

Common Food Packaging Plastic May Contribute to Fatty Liver Disease

Summary

A common type of plastic called polyethylene, used in many food packages, may contribute to fatty liver disease according to new research. The study found that polyethylene alone increased signs of the disease in mice and worsened it when combined with a high-fat, high-sugar diet.

Key Facts

  • Polyethylene is one of the most widely used plastics worldwide, often found in food packaging.
  • Researchers at Texas A&M University studied its effects on fatty liver disease.
  • Fatty liver disease happens when too much fat builds up in liver cells.
  • Exposure to polyethylene increased disease markers in mice.
  • The disease worsened more when mice ate a diet similar to a typical Western diet (high in fat and sugar).
  • Scientists used a technique called spatial transcriptomics to see how genes behaved in the liver tissue.
  • They found proteins and genes related to fat production and tissue repair were involved in the response to polyethylene.
  • Experts say the results are important but caution that more research is needed to know if the same effects happen in humans.
