Associations of Plastic Bottle Exposure with Infant Fecal Microbiota, Short-Chain Fatty Acids, and Growth
AI summary Read the abstract
Researchers investigated associations between plastic bottle use and infant gut health, examining whether exposure influences early fecal microbiota composition, short-chain fatty acid levels, and growth trajectories in infants.
Plastic bottle exposure may impact early infant gut microbiota and microbial SCFAs, which may in turn affect growth.

Associations of Plastic Bottle Exposure with Infant Growth, Fecal Microbiota, and Short-Chain Fatty Acids
AI summary Read the abstract
Researchers examined whether plastic bottle use at three months of age was associated with infant growth, gut microbiota, and short-chain fatty acid levels over the first year of life. They found that plastic bottle frequency was not strongly linked to measures of body fat or growth, and initial associations with gut bacteria were weakened after adjusting for diet. The study calls for further research into health effects from other plastic-based products and direct measurements of microplastic exposure in infants.
Bottle-fed babies may consume millions of microplastic particles, our research suggests
AI summary Read the abstract
Researchers found that shaking polypropylene baby bottles and washing them with hot water releases millions of microplastic particles per liter, suggesting that bottle-fed infants may face unexpectedly high microplastic ingestion and recommending preparation techniques that minimize particle release.
Exposure to polyethylene microplastics alters immature gut microbiome in an infant in vitro gut model
AI summary Read the abstract
Researchers used an artificial infant gut model to study how chronic exposure to polyethylene microplastics affects the developing intestinal microbiome. They found that microplastics shifted gut microbial composition, increasing the abundance of potentially harmful bacteria such as Enterobacteriaceae while decreasing beneficial butyrate production. The study suggests that microplastic ingestion may disrupt the gut microbiome of infants, though no significant damage to the intestinal barrier was observed.
Microplastics-gut microbiota interactions in an in vitro model of the toddler colon
AI summary Read the abstract
Researchers used an in vitro model of the toddler colon to investigate how microplastics interact with the gut microbiota in young children. The study examined changes in microbial community composition and metabolic activity following microplastic exposure, providing early evidence of potential disruption to the developing gut ecosystem.
Microplastics Versus Microbiome: The Infantile Gut’s Battle for Health
AI summary Read the abstract
This review examines how microplastics and nanoplastics disrupt the developing gut microbiome in infants, covering potential effects on microbial stabilization, antibiotic resistance gene transfer through biofilm formation, and implications for long-term metabolic and immune health.
