Plastic can meet food and drinks through packaging, preparation, storage, water, heat, and wear. This Learn section explains what research supports, where uncertainty remains, and which lower-plastic kitchen decisions may be practical.
If you are new to the topic, start with Microplastics 101. It introduces what microplastics are, where common exposure routes may occur, and which everyday kitchen decisions are worth considering first.
One foundational guide before the deeper topic hubs.
Read Microplastics 101A broad evidence guide supported by focused Research & News articles that retain their own methods, limitations, and reader questions.
Learn the difference between detection, experimental hazard, human association, intervention, and clinical outcomes.

Human observations and controlled animal evidence.
What detection means for pregnancy and fetal-transfer questions.
Digestive associations, microbiome evidence, and uncertainty.
Indoor air, respiratory detection, and disease evidence.
Explore where silicone fits in a lower-plastic kitchen, what research says about particles and migration, and how to choose and care for food-contact products.
Begin with the broad answer, then choose the evidence or practical question that matters to you.
Explore Silicone
What particle studies found and where normal-use evidence remains limited.
BPA, siloxanes, curing by-products, and migration testing.
Labels, curing claims, documentation, and the pinch test.
Heat, cleaning, odors, wear, storage, and replacement.
Start with high-use contact points and choose changes that fit your real routine.
Prioritize frequent plastic contact involving heat, wear, storage time, and everyday use.

The metal ball is not the source of the plastic. A new study found that its repeated contact with plastic bottle walls increased microplastic release.

“Not detected” is not the same as zero. A new drinking-water study shows why that distinction matters, without telling us what is in every household’s tap water.

No. The underlying analysis classified chemicals in a database, not products in people's homes. It found that 685 of 738 chemicals with enough toxicity and exposure information met...

A household screening test counted 14 suspected microplastic particles before a Clearly Filtered under-sink system was installed and 1 afterward. The drop is encouraging, but this was one...

Early studies suggest that specific chitosan preparations may change particle counts in a fixed stool subsample or estimated blood measurements. The two human pilots were very small, and...

Studies have measured inhalable microplastics in indoor air and reported plastic particles in human sputum, bronchoalveolar lavage fluid and lung tissue. Controlled animal inhalation and high-exposure workplace studies...
Read the briefPlastic contact does not automatically mean microplastic consumption. Research is still developing, and not every plastic item deserves the same level of attention. We focus on practical contact points involving food, drinks, heat, wear, long storage, and frequent use.
The goal is not a perfect kitchen. It is a kitchen that uses better materials where they can make the most sense.
