ClearMicro(nano)plastics in food system: potential health impacts on human intestinal system.
This review assessed how micro(nano)plastics in the human food system reach the intestine and accumulate in the gut, summarizing evidence that they can alter intestinal barrier function, trigger inflammation, and disrupt the gut microbiome, with implications for long-term digestive health.
Micro(nano)plastics and Their Potential Impact on Human Gut Health: A Narrative Review
This review summarizes research on how micro- and nanoplastics affect the gut, finding that they can damage the intestinal lining, trigger immune responses, and disrupt the balance of beneficial gut bacteria in both cell studies and animal models. Since humans are primarily exposed to microplastics through food and food packaging, understanding these gut effects is essential for assessing the true health risks of plastic pollution.
Impact of micro- and nanoplastics on gastrointestinal diseases: Recent advances
This review summarizes how micro- and nanoplastics can harm the digestive system by causing oxidative stress, inflammation, cell death, and disruption of gut bacteria. These connected pathways can damage the intestinal lining and may contribute to conditions like inflammatory bowel disease and colorectal cancer. The findings highlight the importance of understanding how everyday plastic exposure through food and water could affect gut health over time.
Microplastic: A potential threat to human and animal health by interfering with the intestinal barrier function and changing the intestinal microenvironment
This review summarizes current research on how microplastics disrupt the gut environment in both animals and humans, focusing on damage to the intestinal barrier. Studies show that microplastic exposure can cause oxidative damage, inflammation, destruction of the gut lining, thinning of the protective mucus layer, and disruption of beneficial gut bacteria. While direct human evidence is still limited, the growing body of animal research suggests that microplastics could pose a meaningful threat to intestinal health.
Potential effects of MPs and their co-pollutants on human intestinal tract
This review examines how microplastics and their co-pollutants enter and damage the human intestinal tract, summarizing evidence for microplastic-induced gut barrier disruption, microbiota alteration, and systemic translocation to other organs.
Immunotoxicity and intestinal effects of nano- and microplastics: a review of the literature
This review examines the evidence on how nano- and microplastics affect the immune system and intestinal health. The findings suggest that exposure to these particles can disrupt the gut microbiome and impair critical intestinal barrier functions, potentially contributing to the development of chronic inflammatory and immune conditions.
Orally Ingested Micro- and Nano-Plastics: A Hidden Driver of Inflammatory Bowel Disease and Colorectal Cancer.
This review synthesizes evidence linking ingested micro- and nano-plastics to inflammatory bowel disease and colorectal cancer risk, proposing that microplastics act as a hidden driver of gut inflammation in vulnerable populations. The authors argue that intestinal accumulation of microplastics triggers immune and oxidative stress pathways that contribute to disease progression.
Gut microbiota as an emerging target for the health implications of microplastics
This review examines how microplastic exposure disrupts the gut microbiome, finding evidence that microplastics damage intestinal barrier proteins, promote inflammation and oxidative stress, and may drive systemic effects including neurotoxicity and reproductive toxicity through gut-mediated pathways.
Toxicological assessments based on intestine 3D organoids reveal environmental low-dose nanosized microplastics (NPs) exposure aggravates radiation-induced intestine injury
Using both animal experiments and lab-grown intestinal organoids, researchers found that low-dose nanoplastic exposure worsened radiation-induced intestinal damage. The nanoplastics amplified inflammation and reduced cell growth by activating a specific signaling pathway (TGF-beta1/Smad3) in the gut lining. The study suggests that chronic exposure to even small amounts of nanoplastics could make the intestine more vulnerable to other forms of injury.
Impacts of microplastics on gut health: Current status and future directions
This systematic review found consistent evidence across mouse, fish, and earthworm models that microplastics disrupt gut microbiota composition, impair intestinal barrier integrity, and trigger gastrointestinal inflammation. The correlation between microplastic exposure and gut health deterioration was statistically significant across all animal models examined.
[Effect of microand nanoplastics on the gastrointestinal mucosa and intestinal microbiome].
This review examines how micro- and nanoplastics entering through the food chain affect the gastrointestinal tract, finding evidence of disruption to gut mucosal integrity and intestinal microbiome composition, with implications for digestive health and systemic immune function.
Recent Progress in Intestinal Toxicity of Microplastics and Nanoplastics: Systematic Review of Preclinical Evidence
This systematic review of animal studies from 2021 to 2024 found growing evidence that swallowed microplastics and nanoplastics can damage the gut. Effects include inflammation, weakened gut barriers, oxidative stress, and disrupted gut bacteria. These findings suggest that the plastic particles found in our food could pose a risk to digestive health, though more research with realistic exposure levels is needed.
Perturbation of gut microbiota plays an important role in micro/nanoplastics-induced gut barrier dysfunction
Researchers investigated how micro- and nanoplastics disrupt gut barrier function in mice, finding that different surface chemistries caused varying levels of damage. The study suggests that these plastic particles harm the gut by altering the gut microbiome, which then leads to inflammation and weakening of the intestinal barrier that normally keeps harmful substances out of the body.
Micro- and nano-plastics, intestinal inflammation, and inflammatory bowel disease: A review of the literature
This review summarizes the growing evidence linking micro- and nanoplastic exposure to intestinal inflammation and inflammatory bowel disease (IBD). Studies show these tiny plastic particles can trigger immune responses in the gut, alter the gut microbiome, and worsen intestinal inflammation, though more research using standardized methods is needed to confirm these effects in humans.
An innovative in vitro model of IBD to assess micro-/nano-plastics intestinal toxicity.
Researchers developed an innovative in vitro intestinal inflammation model (IBD model) to assess the toxicity of micro- and nanoplastics at realistic concentrations and polymer types, moving beyond the high-dose polystyrene-only studies that dominate current literature.
