Green tea conclusions

"
Current research evidence for the efficacy of green tea to prevent cancer is weak. Epidemiological studies have been conducted to investigate the relationship between the consumption of green tea and the risk of developing cancer. Contradictory findings have been found in relation to incidence of cancer and drinking green tea, within both cohort studies and case-control studies. The majority of the studies showed that green tea may prevent the occurrence of some forms of cancer, especially gastrointestinal cancers, such as oesophogeal, stomach, pancreatic, liver, and colorectal cancers. However, evidence from randomised trials is insufficient to confirm the efficacy of green tea for preventing cancers.
