1.Keep it cool. Repeatedly drinking hot beverages may boost the risk of esophageal cancer. Give tea several minutes to cool off before sipping.
2.The studies seem convincing, but a rat does not a human make. Chemicals in tea may react differently in the lab than they do in the human body. Tannins (and the other good stuff in green tea) may not be bioavailable for humans, meaning tea might not always benefit human health to the same degree as in lab studies suggest.
