Are microplastics driving childhood asthma rates?

What's actually in it

Your child is likely eating microplastics every day. A 2026 study in Sci Total Environ confirms that common items like plastic-wrapped candies are a source of microplastic exposure for kids. These particles are not just sitting in the packaging. They end up in the food your child eats.

Once ingested, these materials may interact with the body in ways we are only beginning to understand. For instance, a 2026 study in SAR QSAR Environ Res highlights that polystyrene microplastics can play a role in childhood obesity through complex biological pathways.

What the research says

While many parents worry about the link between plastic and asthma, the current peer-reviewed research focuses on different environmental triggers. A 2026 study in Am J Epidemiol examined how metal mixtures during pregnancy impact lung function and asthma in children. This research shows that internal exposure to certain substances early in life is a major factor in how a child's lungs develop.

Additionally, a 2026 study in Environ Int looked at air pollution levels and childhood asthma. This science confirms that even in areas with low pollution, environmental factors remain critical to understanding why asthma rates change. While we know microplastics are in our food supply, the specific link to asthma is still being studied. We are keeping a close watch on the data as it emerges.
