Science shows that plastic teabags release billions of microplastic and nanoplastic particles per cup when steeped in hot water, along with phthalate plasticizers linked to cancer risk with habitual consumption. Loose tea contains markedly lower contamination levels. Brewing vessels matter too: plastic-lined paper cups release tens of thousands of particles into hot liquids within minutes, plus toxic metals like lead and cadmium. Research indicates these particles can be absorbed by intestinal cells and trigger inflammatory responses.
This is HIGH PRIORITY because tea is steeped at high temperatures for extended periods, which dramatically increases microplastic and chemical leaching. Many people drink multiple cups daily, creating concerning cumulative exposure.
Laurel recommends tea kettles, strainers, and water boilers made from relatively intert materials like glass, stainless steel, or ceramic. For tea itself, choose loose leaf tea (even teabags made of "paper" have been shown to release microplastics).
Laurel avoids tea products with plastic components that come into contact with hot water.
Tip: Swap teabags for a simple stainless steel infuser with loose leaf tea. This reduces microplastic exposure by orders of magnitude and often tastes better, too!
