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.
Detection of Microplastics in Human Breast Milk and Its Association with Changes in Human Milk Bacterial Microbiota
Researchers detected microplastics in nearly 39% of breast milk samples from 59 mothers, with polypropylene and polyethylene being the most common types found. The presence of microplastics was linked to changes in the bacterial makeup of breast milk, raising concerns about early-life microplastic exposure in infants during breastfeeding.
Exposure to polyethylene microplastics alters immature gut microbiome in an infant in vitro gut model
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.
Occurrence of Polyethylene Terephthalate and Polycarbonate Microplastics in Infant and Adult Feces
Researchers measured microplastic levels in the stool of infants and adults in New York and found that infants had significantly higher concentrations of PET microplastics, about ten times more than adults. The likely sources include plastic baby bottles, food packaging, and toys that infants frequently put in their mouths. This study provides some of the first direct evidence that babies are exposed to more microplastics than adults, raising questions about potential health effects during early development.
Detection of various microplastics in placentas, meconium, infant feces, breastmilk and infant formula: A pilot prospective study
In a pilot study of 18 mother-infant pairs, researchers detected microplastics in placentas, meconium (first stool), infant feces, breast milk, and infant formula. The finding of microplastics in breast milk and formula means that infants are exposed to microplastics from their earliest feedings, both natural and artificial. This study reveals that microplastic exposure begins before birth and continues through infancy, a critical period of development.
Exposure of Infants to Microplastics
This study examines the routes through which infants may be exposed to microplastics, including through infant formula and plastic feeding containers. Researchers note that infants are particularly vulnerable because their metabolic systems are still developing and less capable of processing foreign particles. The findings highlight the need for more research into the specific risks microplastic exposure poses to infant health.
Microplastic Exposure to Infants
This review summarizes current evidence on microplastic exposure in infants, covering detection in feces, breast milk, and infant formulas. The authors highlight that infants may face greater health risks from microplastic exposure than adults due to immature metabolic systems and higher sensitivity.
Impact of Ex Vivo Bisphenol A Exposure on Gut Microbiota Dysbiosis and Its Association with Childhood Obesity
This pilot study exposed gut bacteria from obese and normal-weight children to bisphenol A (BPA), a chemical commonly found in plastics, and found it disrupted the balance of intestinal microbes. Some of the bacterial changes caused by BPA exposure looked similar to patterns already seen in obese children, suggesting a possible link between plastic chemical exposure and childhood obesity through gut bacteria. Since BPA is a common additive in plastics that generate microplastics, this research highlights another pathway through which plastic pollution may affect children's health.
Microplastics-gut microbiota interactions in an in vitro model of the toddler colon
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
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.
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.
Polystyrene Microplastics Disrupt Vertical Transmission of the Breast Milk Microbiome, Impairing Early‐Life Gut Colonization and Immune Development in Offspring
Researchers exposed pregnant and lactating mice to polystyrene microplastics and found that maternal exposure disrupted the breast milk microbiome, reducing beneficial bacteria like Ligilactobacillus while increasing potentially harmful ones. Offspring from exposed mothers showed altered gut colonization, excessive weight gain, reduced immune markers, and compromised intestinal barrier integrity, suggesting microplastics may affect infant development through changes in breast milk composition.
Isolation and identification of microplastics in infant formulas – A potential health risk for children
Researchers tested 30 infant formula products and found microplastics in every single one, with polyamide, polyethylene, polypropylene, and PET being the most common types. They estimated that formula-fed babies consume about 49 microplastic particles per day through their formula alone. This is concerning because infants are especially vulnerable to potential health effects from microplastics during critical stages of development.
The Overview of the Possible Exposure of Infants to Microplastics
This review examines the various ways infants can be exposed to microplastics, including through breast milk, formula, baby food, plastic bottles, and toys. Researchers note that infants may be especially vulnerable because their metabolic and immune systems are still developing, potentially making them less able to process or eliminate these particles. The study calls for more research into infant-specific exposure levels and health effects, as current data remains limited.
Release of microplastics from breastmilk storage bags and assessment of intake by infants: A preliminary study
Researchers tested six commercially available breastmilk storage bags and found they released large numbers of microplastic and submicron particles during simulated normal use. The particles were identified as plastics using spectroscopy analysis, raising questions about infant exposure through stored breastmilk. The study suggests that single-use plastic baby food packaging may be an overlooked source of microplastic ingestion for infants.
Microplastics and child health: A scoping review of prenatal and early-life exposure routes and potential health risks
This scoping review examined how microplastics reach children through prenatal and early-life exposure routes, including placental transfer, breast milk, formula, and feeding bottles. The evidence indicates that microplastic exposure begins before birth and continues through infancy via multiple pathways, raising concerns about potential developmental health effects during these particularly vulnerable life stages.
What Health Concerns Could Micro and Nanoplastics Pose for Infants? A Review
Microplastics and nanoplastics have been detected in human placentas, meconium, and infant faeces, meaning babies can be exposed before and immediately after birth. This review examines what these early-life exposures might mean for infant health and development, and discusses broader policy responses to reduce plastic overproduction as the most direct route to protecting future generations.
An Overview of the Possible Exposure of Infants to Microplastics
This review summarizes the ways infants can be exposed to microplastics, including through the placenta before birth, breast milk, infant formula, plastic feeding bottles, and toys. Infants may face higher risks because their bodies are still developing and are less able to process and remove these particles. The authors call for more research and greater attention to reducing microplastic exposure in products designed for babies.
The Association Between Microplastics and Microbiota in Placentas and Meconium: The First Evidence in Humans
Researchers analyzed placentas and meconium from 18 mother-infant pairs in Shanghai and found microplastics present in both, providing some of the first direct evidence of microplastic exposure during pregnancy and at birth. They also discovered correlations between microplastic presence and changes in microbial communities in these tissues. The study raises important questions about whether early-life microplastic exposure could influence infant health and development.
Polypropylene micro- and nanoplastics affect the digestion of cow's milk proteins in infant model of gastric digestion
Researchers found that polypropylene micro- and nanoplastics, commonly released from baby bottles during heating, interfere with the digestion of milk proteins in a simulated infant stomach model. The plastic particles bound to milk proteins and changed how they were broken down by digestive enzymes, with the effect being stronger in the infant model than in the adult model. This is concerning because incomplete protein digestion in infants could affect nutrient absorption during a critical period of growth and development.
