Can microplastics from food packaging relate to inflammation markers?
A 2026 adult stool study linked higher microplastic levels with an inflammation-related marker. Plastic food containers can release microplastics, so glass storage is a practical way to lower daily contact.
What we know
A 2025 Food Chemistry study measured microplastics released from plastic food containers. The study found release during rinsing and migration testing, with more release under some food and temperature conditions.
A 2026 Environmental Health and Preventive Medicine study measured microplastics in stool from 22 healthy Japanese adults. People with higher stool microplastic density had higher thymic stromal lymphopoietin, an inflammation-related marker.
What this means for your family
This does not prove that food packaging causes chronic inflammation in babies. The human study was small and done in adults. Still, the evidence supports reducing plastic contact with food where it is easy.
Glass is a clear next step because it does not release plastic particles into food.
Simple safer steps
Store leftovers in glass containers. Move warm takeout into glass at home. Use stainless steel or glass for daily snacks and packed food when you can.
