Research has even suggested that green tea may be effective at treating patients who already have cancer. Several studies, on different forms of cancer, have shown that traditional cancer treatments, such as chemotherapy, are more effective when green tea is administered along with the treatment.

Green tea seems to increase the concentration of the drugs in the cancerous cells and slows down cancer progression, perhaps even preventing metastasis.

Much of the research that has been performed has been on mice or in-vitro, though the study outlined above was performed on humans. The next step in truly understanding how foods, including tea, can protect our health, preventing cancer and other disease, is to conduct more human trials.

The results could take years, because human trials on prevention require following subjects over a long period of time.

Preventing cancer is a national health concern. Certainly, much more study is required before we can gain true understanding of how to protect our health. One thing’s for sure, however; a diet rich in fruits, vegetables and tea is a good start!
