ClearTake-out food enhances the risk of MPs ingestion and obesity, altering the gut microbiome in young adults
A study of 121 young adults found that those who frequently ordered takeout food had significantly higher levels of microplastics in their stool and higher body mass index (BMI). The high-microplastic group also showed changes in gut bacteria linked to poorer health, including increases in harmful species and decreases in beneficial ones. These findings suggest that takeout food packaging may be a meaningful source of microplastic exposure that could contribute to obesity risk.
Alterations of gut and oral microbiota in the individuals consuming take-away food in disposable plastic containers
Researchers examined gut and oral microbiota changes in people who frequently consume take-away food from disposable plastic containers. The study found that both occasional and frequent consumers had altered gut and oral bacterial communities compared to non-consumers, and a mouse experiment confirmed that reducing but not eliminating micro- and nanoplastic exposure did not fully reverse gut microbial changes.
Microplastics in stools and their influencing factors among young adults from three cities in China: A multicenter cross-sectional study
In a study of 78 college students across three Chinese cities, microplastics were detected in the stool of nearly every participant, with a median concentration of about 55 micrograms per gram. People who ate more takeout food had significantly higher microplastic levels in their stool. This is one of the first studies to measure the actual mass of microplastics passing through young adults' digestive systems, confirming that diet and food packaging directly influence human exposure.
Occurrence of microplastics and disturbance of gut microbiota: a pilot study of preschool children in Xiamen, China
In a study of preschool children in Xiamen, China, researchers found microplastics in the stool of every child tested, with polycarbonate and PVC being the most common types. Children who frequently used plastic containers and ate takeout food had higher microplastic levels. The study also found that higher microplastic exposure was linked to changes in gut bacteria, including lower levels of beneficial microbes.
Study on the association between microplastic exposure and gut microbiota based on metagenomics: A pilot study on 66 young college students in China
In a pilot study of 66 young college students in China, researchers analyzed stool samples to examine the relationship between microplastic exposure and gut microbiota composition. Participants with higher microplastic concentrations in their stools showed increased abundance of potentially harmful intestinal bacteria, with polystyrene microplastics having the most pronounced effect on gut microbial community structure.
You are what you eat: Microplastics in the feces of young men living in Beijing

They found microplastics in all samples, with the amount correlating to the participants' consumption of packaged food and beverages, providing direct evidence that people are regularly ingesting microplastics through their diet.
Detection of Various Microplastics in Human Stool
Researchers analyzed human stool samples and detected various types of microplastic particles, providing direct evidence that microplastics pass through the human digestive system. The study highlights that people are routinely ingesting microplastics through everyday food and drink consumption.
Single exposure of food-derived polyethylene and polystyrene microplastics profoundly affects gut microbiome in an in vitro colon model
Using a lab model of the human colon, researchers found that a single exposure to polyethylene and polystyrene microplastics, at levels matching a typical meal, significantly disrupted the gut microbiome. Harmful bacteria overgrew while beneficial bacteria declined, and the balance of bacterial metabolism shifted in unhealthy ways. This suggests that even routine dietary microplastic intake could alter gut health in humans.
Assessment of microplastics in human stool: A pilot study investigating the potential impact of diet-associated scenarios on oral microplastics exposure
In this pilot study, 15 volunteers followed different plastic-use and food consumption scenarios, and microplastics were detected in every stool sample collected, with polyethylene being the most common type. Using plastic packaging for food and eating highly processed foods were statistically linked to higher microplastic levels in stool, providing early evidence that dietary choices influence how many microplastics people ingest.
Association between microplastics exposure and gut microbiota and metabolites in older adults: A cross-sectional study
Researchers analyzed fecal samples from 45 older adults to assess the relationship between microplastic exposure and gut microbiota. They found an average of 70 microplastic particles per gram of feces, primarily PVC, butadiene rubber, and polyethylene, and observed that microplastic exposure was associated with changes in gut microbial diversity and metabolite levels. The study suggests that microplastics may influence gut health in older adults by altering bacterial community composition and metabolic pathways.
Gut microbiome remodeling induced by microplastic exposure in humans
This review synthesizes evidence on how microplastic exposure affects the human gut microbiome, drawing on cross-sectional studies of people exposed through plastic food containers and other sources. Evidence indicates that microplastic exposure is associated with shifts in gut bacteria composition, including increases in certain bacterial groups linked to inflammation. The authors explore potential connections between microplastic-induced changes in gut bacteria and the development of various health conditions.
Polyethylene terephthalate microplastics affect gut microbiota distribution and intestinal damage in mice
Mice exposed to PET microplastics, the type commonly found in plastic bottles, developed intestinal inflammation, changes in gut bacteria, and signs of a weakened gut barrier. Even at relatively low doses, the microplastics increased liver stress markers and disrupted the protective mucus layer in the colon, suggesting that everyday PET plastic exposure could contribute to digestive health problems.
Relationship between microplastics in stool, diet, and inflammatory markers in healthy Japanese individuals
Researchers investigated the relationship between microplastics found in stool, dietary intake, and inflammatory markers in healthy Japanese individuals who typically consume a diet high in vegetables and seafood. The study explored how different types of microplastics in the intestinal tract may correlate with gastrointestinal inflammation and oxidative stress markers. The findings contribute to understanding how dietary habits influence microplastic exposure and its potential effects on gut health.
Microplastic-induced gut microbiota and serum metabolic disruption in Sprague-Dawley rats
Researchers exposed rats to a mixture of common microplastic types at concentrations reflecting real-world human exposure and found significant disruptions to gut bacteria and blood metabolites. The microplastic mixture altered the balance of beneficial and harmful gut microbes and changed metabolic pathways related to amino acids and lipids. The study suggests that everyday microplastic exposure from food and water may affect mammalian gut health and metabolism.
Microplastics in take-out food containers
Scientists collected take-out food containers made from four polymer types in five Chinese cities and detected microplastics in all containers, with fragment counts and polymer compositions varying by container material and city of origin.
Microplastics in take-out food: Are we over taking it?
This study measured microplastic abundance and characteristics in 146 take-out food samples including rice, noodles, bubble tea, and coffee from disposable containers. The mean abundance was 639 microplastics per kilogram, with rice having the highest contamination, and the majority were fragments and fibers consistent with packaging and handling materials.
Microplastics in human feces: a pilot study exploring links with dietary habits
Researchers analyzed fecal samples from 18 people in Norway and found microplastics in 17 of them, with polypropylene being the most common polymer, but found no significant link between seafood consumption and microplastic levels. The results suggest that dietary habits alone do not determine exposure, and that microplastics may enter the body through many everyday sources beyond food.
Microplastics in human feces and their correlation with dietary behavior: A pilot study
This pilot study analyzed microplastics in human fecal samples and examined correlations with dietary habits, finding that seafood and packaged food consumption were associated with higher fecal microplastic counts. The results provide early evidence linking diet to human microplastic exposure levels.
Impact of microplastics on the human gut microbiome: a systematic review of microbial composition, diversity, and metabolic disruptions
This systematic review of 12 studies found that microplastics including polyethylene, polystyrene, and PVC induce gut dysbiosis in humans, reducing beneficial bacteria and enriching pathogens. Microplastic exposure also impairs short-chain fatty acid production and modulates immune pathways, contributing to intestinal disease, metabolic syndrome, and chronic inflammation.
Intestinal Microplastic Retention Reshapes Gut Microbial Ecology through Surface-Associated Colonization and Additive Leaching
Researchers used an advanced gut simulation model to study how retained PET microplastics affect the human intestinal microbiome. They found that microplastics promoted colonization by potentially harmful bacteria on their rough, hydrophobic surfaces while displacing beneficial gut microbes. Additionally, chemical additives leaching from the plastics independently shifted microbial composition, suggesting that microplastics may alter gut ecology through both physical and chemical mechanisms.
Impact of microplastics on the intestinal microbiota: A systematic review of preclinical evidence
Across 28 preclinical studies, microplastics triggered intestinal dysbiosis characterized by increased Firmicutes and Proteobacteria and decreased Bacteroidetes, while increasing gut permeability and elevating pro-inflammatory cytokines including IL-1β, TNF-α, and IL-6.
Effects of thermal exposure to disposable plastic tableware on human gut microbiota and metabolites: A quasi-experimental study
In a human study, people who ate hot food from disposable plastic tableware for one month had more microplastics in their stool and significant changes in their gut bacteria and urine metabolites compared to those using non-plastic dishes. The changes were linked to effects on the nervous system, energy metabolism, and inflammation, and some gut bacteria shifts persisted even after stopping plastic tableware use. This is one of the few direct human studies showing that everyday plastic food containers release microplastics that measurably change gut health.
Analysis of Microplastics in Human Feces Reveals a Correlation between Fecal Microplastics and Inflammatory Bowel Disease Status
Researchers analyzed microplastics in the stool of patients with inflammatory bowel disease (IBD) and healthy volunteers, finding that IBD patients had significantly higher concentrations of microplastics in their feces. PET plastic and polyamide were the most common types found, likely originating from food packaging and dust. The positive correlation between microplastic levels and IBD severity suggests that microplastic exposure may be linked to gut inflammation, though it is not yet clear whether the plastics contribute to the disease or the disease causes more plastic retention.
Impact of microplastics on human gut microbiota: first evidences from in vitro gut models
Researchers investigated the impact of microplastics on human gut microbiota using in vitro gut models, providing early experimental evidence of how microplastic exposure may disrupt intestinal microbial communities.
