Quercetin intervention mitigates small intestinal damage and immunologic derangement induced by polystyrene nanoplastics: Insights from multi-omics analysis in mice
Researchers found that quercetin, a natural compound found in fruits and vegetables, protected mice from gut damage and immune system disruption caused by polystyrene nanoplastics. The nanoplastics damaged the small intestine and disrupted immune balance, but quercetin reversed much of this harm by restoring healthy gut bacteria and gene activity. This suggests that dietary compounds like quercetin might help counteract some negative health effects of nanoplastic exposure.
Food-derived cyanidin-3-O-glucoside reverses microplastic toxicity via promoting discharge and modulating the gut microbiota in mice
Researchers found that cyanidin-3-O-glucoside (C3G), a naturally occurring anthocyanin compound found in many fruits and vegetables, helped reduce the harmful effects of polystyrene microplastics in mice. C3G supplementation promoted the excretion of microplastics, reduced tissue accumulation, and alleviated oxidative stress and inflammation caused by the particles. The study also showed that C3G helped restore healthy gut microbiota that had been disrupted by microplastic exposure.
Considering the Importance of Medicinal Plants and Natural Products and Their Mechanisms of Action for Treatment of Gastrointestinal Disorders
This bibliometric analysis of over a thousand articles reviewed medicinal plants and natural products for treating gastrointestinal disorders, highlighting their anti-inflammatory, antioxidant, and gut-protective mechanisms. While not focused on microplastics, the gut-protective properties of certain natural compounds are relevant to understanding how to mitigate gastrointestinal damage from environmental contaminants.
Modulation of Gut Microbial Metabolism by Cyanidin-3-O-Glucoside in Mitigating Polystyrene-Induced Colonic Inflammation: Insights from 16S rRNA Sequencing and Metabolomics
A natural plant compound called cyanidin-3-O-glucoside (C3G), found in red bayberry and other berries, reduced colon inflammation caused by polystyrene microplastic exposure in mice. C3G worked by reshaping the gut bacteria community and restoring healthy levels of anti-inflammatory signaling molecules. This suggests that certain dietary antioxidants may help protect the gut from damage caused by microplastic exposure.
Effects induced by polyethylene microplastics oral exposure on colon mucin release, inflammation, gut microflora composition and metabolism in mice
Researchers fed mice polyethylene microplastics for 30 days and found that even low doses reduced protective mucus in the colon, altered inflammation markers, and shifted the composition of gut bacteria. The microplastics increased the ratio of Bacteroides to Firmicutes bacteria and affected metabolic pathways in the gut microbiome. The study suggests that oral microplastic exposure may disrupt intestinal health by modifying the gut microbial community and its metabolism.
Lactic acid bacteria reduce polystyrene micro- and nanoplastics-induced toxicity through their bio-binding capacity and gut environment repair ability
Researchers found that lactic acid bacteria, the kind used in yogurt and fermented foods, can reduce the toxic effects of polystyrene micro and nanoplastics in mice. The bacteria worked by physically binding to the plastic particles and by repairing damage to the gut lining and restoring healthy gut bacteria populations. This suggests that probiotics could be a practical way to help protect the digestive system from the harmful effects of microplastic exposure through food and water.
Maltol attenuates polystyrene nanoplastic-induced enterotoxicity by promoting AMPK/mTOR/TFEB-mediated autophagy and modulating gut microbiota
Researchers found that maltol, a natural food flavoring compound, can protect against intestinal damage caused by polystyrene nanoplastics in mice.
