Keurig coffee makers may release microplastics into brewed coffee

Research highlighted by Tasting Table indicates that standard K‑Cup pods, made largely of polypropylene, can shed tiny plastic fragments when hot water is forced through them during brewing. These microplastics—particles smaller than a fifth of an inch—may end up in the coffee cup. While scientific studies on the health effects of ingesting microplastics are still limited, experts warn that repeated low‑level exposure could carry chemicals that interfere with hormones and has been linked to cancer, diabetes, reproductive and developmental issues. The concern is not limited to a single cup; the cumulative exposure from many sources, including bottled water and food, is prompting closer scrutiny. Consumers are advised to reduce exposure by considering alternative brewing methods or using reusable filters, though the article notes that a single pod‑brew is unlikely to cause immediate health problems.
