Relationship between microplastics in stool, diet, and inflammatory markers in healthy Japanese individuals
Summary
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.
Background: Exposure to microplastics (MPs) can have adverse gastrointestinal effects by inducing inflammation and oxidative stress. The types of MPs in stool vary with the dietary intake. However, how MPs in the intestinal tract influence the inflammatory cytokine levels in the gastrointestinal tract in healthy individuals remains unclear, particularly in Japan, characterized by a high intake of vegetables and seafood. In this study, we investigated the relationship between food intake, stool MPs, and inflammatory markers in healthy Japanese individuals, and estimated the sources of the stool MPs.

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.
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.
Analysis\nof Microplastics in Human Feces Reveals a\nCorrelation between Fecal Microplastics and Inflammatory Bowel Disease\nStatus
Researchers found higher concentrations and greater diversity of microplastics in fecal samples from inflammatory bowel disease patients compared to healthy controls, suggesting a potential association between microplastic ingestion and gut inflammation, though causality remains to be established.
Take-out containers as nano- and microplastics reservoirs: Diet-driven gut dysbiosis in university students
Researchers analyzed stool samples from 24 university students and found microplastics in every sample, with students who frequently ate from plastic take-out containers having significantly higher levels. The most common plastic type was PET, likely from food packaging. Higher microplastic levels were associated with changes in gut bacteria composition, suggesting that everyday habits like eating take-out food could disrupt gut health through microplastic exposure.
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.
