Jane Says: What You Should Know About Lead in Green Tea

The difference between green and black tea, by the way, is based on the degree of oxidation the leaves receive. Green tea comes from leaves that are steamed, pan-fired, or oven-fired immediately after picking, so minimal oxidation occurs. (White tea, made from new-growth buds and young leaves, is even less processed.) In a black tea—or red tea, as it’s called in China—the leaves are well and truly oxidized. The type of tea called oolong occupies the middle range; its partial oxidation results in varying, distinctive flavors and complex aromas.
All teas are rich in antioxidants, but green tea, especially when brewed from loose leaves, is known for its great abundance of the polyphenols classified as catechins—in particular, epigallocatechin-3-gallate (EGCG). A great deal has been written about the health benefits of green tea, so I’ll spare you here; for an in-depth review, check out this research from the University of Granada , in Spain.
