  4. Anton Rietveld and Sheila Wiseman. Antioxidant Effects of Tea: Evidence from Human Clinical Trials. J. Nutr. 133: 3285S-3292S, 2003. Green tea : antioxidant effects • Tea flavonoids are potent antioxidants. • The scientific support is strongest for the protection of DNA from oxidative damage after black or green tea consumption. • However, the quality of the studies now available is insufficient to draw firm conclusions. • Therefore, further evidence from human intervention studies is required.

  5. Green tea and cancer Blot WJ, Chow WH, McLaughlin JK.Tea and cancer: a review of the epidemiological evidence. Eur J Cancer Prev. 1996 Dec;5(6):425-38. Numerous reports : inhibition of carcinogenesis in experimental animals by tea. Ecological data : considerable international variation in tea consumption but generally small differences in cancer rates. More relevant case-control and cohort studies show mixed results. Further research, is needed before definitive conclusions on tea's impact upon cancer risk can be reached.
