I'm not drinking tea because of any of its many (true or false) health benefits. I just happen to like it so much! But like everybody, I am afraid of getting sick (and dying), and would like to believe in some of the claims made about tea.
One interesting site I found is Optimal Life Center. Amazingly, it does not report any of the research (hype?) about tea. Nevertheless, if you drink gong fu cha, then you are already following several of the recommendations of this site:
1. You pay attention to water quality,
2. You drink lots of water when drinking tea (water is the mother of tea!),
3. You don't add any refined sugar with Chinese tea,
4. You experience harmony and positive emotions that strengthen your immune system.
Lechaim, prost, santé!
