Microplastics in human feces and their correlation with dietary behavior: A pilot study
Summary
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.
The global surge in plastic pollution has raised significant environmental concerns in recent decades. Subsequently, microplastics (MPs) have been detected in various environmental matrices and food chains, prompting investigations into potential human exposure. Evidence suggests that humans are ingesting MPs through several foods and beverage sources. Moreover, recent studies have reported the presence of MPs in selected human samples, including fecal matter. Fecal analysis provides a non-invasive method for detecting MP ingestion, yet research on MPs in feces, particularly their association with human diet, remains limited. This is a pilot study to provide evidence of microplastic presence in the human gastrointestinal tract through fecal analysis and evaluate its correlation with human dietary habits.

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.
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.
You are what you eat: Microplastics in the feces of young men living in Beijing
Researchers collected and analyzed fecal samples from 26 young men in Beijing to measure microplastic content. 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.
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.
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.
