Question:
How significant are the risks to drinking tea from China from heavy metals?

Answer:
ConsumerLab.com and other research groups have found significant amounts of lead contaminating some teas from China. Contamination is most common in tea made from older leaves, as in black tea and Oolong tea, than from younger leaves used to make green tea. However, there are ways to reduce the health risks posed by contaminated products, as discussed in the "Lead" section of ConsumerLab.com's Green Tea Review >>. The Review includes test results and comparisons for teas sold loose, in tea bags, as matcha powder, and even as a K-Cup.
