health π¬ Tea bags shed plastic, but the science is complex
Certain nylon and PET pyramid tea bags shed microplastics when steeped in hot water. A 2019 McGill University study claimed a single cup could hold about 11.6 billion particles. However, a German agency disputed the counting method as potentially contaminated. Research on how ingested microplastics affect human health remains essentially absent. Consumers can choose loose-leaf or paper bags to avoid this specific plastic variable. π΅
