Polyethylene Microplastics and Mitochondrial-Redox Dysfunction in Preclinical Rodent Models: A Systematic Review and Meta-Analysis of Bioenergetic and Oxidative Stress Outcomes

Summary

This review pulled together existing animal studies on tiny plastic particles (polyethylene microplastics, common in packaging and everyday products) and found a consistent pattern: these particles seem to damage mitochondria, the "power plants" inside our cells, and trigger harmful oxidative stress, which can wear down tissues over time. Since this research is in rodents, not humans, more studies are needed to confirm the same effects happen in people, but the findings raise real concerns about how the microplastics we're increasingly exposed to might affect long-term cellular health and energy production in our bodies.
