2) Green tea may help explain lower cancer rates in Asia NEW YORK - While smoking is a well-known cause of heart disease and lung cancer, the rates of these diseases have remained inexplicably low in Asian countries where smoking is common. But researchers say there is growing evidence that green tea is one piece of the puzzle. Writing in the Journal of the American College of Surgeons, Yale University researchers detail the body of evidence linking green tea to better heart health and a lower risk of cancer. Read more...

3) Mayo Clinic Researchers Discover Green Tea Component Helps Kill Leukemia Cells
Mayo Clinic researchers have discovered that a component in green tea helps kill cells of the most common leukemia in the United States. The research using laboratory cell cultures shows that a component of green tea known as epigallocatechin-3-gallate (EGCG) [epi-gallo-cat-ekin-3-gal-ate] helps kill leukemia cells by interrupting the communication signals they need to survive. The findings are reported in an early electronic article in the journal Blood. The leukemia cells studied were from patients with B-cell chronic lymphocytic leukemia (CLL) -- most often diagnosed in patients in their mid-to-late 60s. Currently, there is no cure for CLL, though chemotherapy is administered in the most severe cases. The Mayo Clinic study, led by Neil E. Kay, M.D., shows that green tea's EGCG interrupted survival signals, prompting leukemia cells to die in eight of 10 patient samples tested in the laboratory. Says Dr. Kay: "We're continuing to look for therapeutic agents that are nontoxic to the patient but kill cancer cells, and this finding with EGCG is an excellent start. Understanding this mechanism and getting these positive early results gives us a lot to work with in terms of offering patients with this disease more effective, easily tolerated therapies earlier."
