Alarm raised by experts following disturbing link to rise in liver issues: 'First scientific proof provided'

Plastic takes centuries to decompose, and during this slow breakdown, tiny fragments known as microplastics can contaminate our water, food, and air. Recent studies are raising alarms that these minuscule particles may also cause significant damage within the body.

New research published in PLOS One has linked microplastic exposure to liver issues in mice. Given that most humans encounter microplastics daily, these findings could have long-term implications for human health.

The study observed mice exposed to polystyrene microplastics for nine weeks. Results showed a noticeable decline in liver metabolic function. Microplastics were detected inside liver tissue, disrupting the normal processing of fats, glucose, and amino acids.

Researchers also noted alterations in gut bacteria associated with liver function. Since previous studies had not reported such changes in this mouse model, the team emphasized the need for further investigation into how microplastic-induced liver damage impacts gut microbiota. Nonetheless, the study provided the first evidence linking microplastic exposure to gut microbiome disruption.

"No prior research had documented gut microbiota changes in Lep KO mice. This study presents the first scientific proof of microbiota disruption in these mice following microplastic exposure," the authors reported.

Liver damage can impair the body's ability to manage toxins, fats, and blood sugar, increasing the risk of chronic diseases. Additional studies have also connected polystyrene microplastics to kidney disease in mice. Other research at Cornell University confirmed the presence of microplastics in common foods, highlighting potential long-term health hazards.

Minimizing plastic contact with food is one way to reduce exposure. Using reusable containers instead of single-use plastics and choosing plant-based foods can help lower plastic waste and limit contact with microplastics.

Awareness of these environmental and health risks can help families and communities make choices that support long-term well-being for both humans and the planet.
