What’s in Your Green Tea?

The report was published this week by ConsumerLab.com, an independent site that tests health products of all kinds. The company, which had previously tested a variety of green tea supplements typically found in health food stores, took a close look at brewed and bottled green tea products, a segment that has grown rapidly since the 1990s.
It found that green tea brewed from loose tea leaves was perhaps the best and most potent source of antioxidants like epigallocatechin gallate, or EGCG, though plain and simple tea bags made by Lipton and Bigelow were the most cost-efficient source.

Dr. Cooperman said the tea leaves containing lead probably originated in China, where studies have found that industrial pollution causes the leaves in some regions to gather substantial amounts of lead. The Teavana leaves came from Japan, where that is less of a problem, he said. The decaffeination process also helps remove lead.
Still, the study found that there was no real prospect of a health concern from the lead. The liquid portions of the teas that were brewed and tested contained very little if any of the metal, Dr. Cooperman said.
