That quick takeout meal may come with an unexpected cost. A new study found that people who ate takeout frequently had much higher levels of microplastics in their bodies, along with gut changes linked to inflammation and poor health.
Researchers analyzed stool samples from healthy students and discovered microplastics in every participant. Those who ate takeout three or more times a day had the highest levels — an average of 171 to 269 plastic particles per 100 grams of feces. Most were PET fibers, the same plastic used in bottles and packaging.
The study also found that students with the highest exposure showed gut microbiome changes, including fewer beneficial microbes, weaker gut barriers, and more bacteria tied to inflammation. Researchers say these findings highlight the urgent need for stronger plastic regulations and more research into how everyday exposure may affect long-term health.
