Whenever we talk about the health benefits of tea we have to be careful to stay balanced in our interpretation of the data but we should not be frightened of sharing the incredible wealth of evidence out there that shows the health-giving properties of Tea - after all it is the first Chinese medicine and has been used medicinally for millennia.
IMPORTANT CORRECTIONS:
1. In this video, I conflated RR (risk reduction) with OR (odds ratio) and therefore some of the risk reduction statements should be rephrased as Odds Ratios.
2. The protection against Hepatic and Renal damage in Diabetes was actually an animal study.
