Green tea and colorectal cancer:
Amount of green tea consumption and risk of colorectal cancer: Researchers conducted an extensive large population-based case-control study in Shanghai, China in order to see whether green tea consumption had any impact on cancers of the colons, rectum, and pancreas. The research team found that the greater the consumption of green tea, the lesser the risk of cancer. Odds ratios were used with 95% confidence intervals to determine odds of developing various cancers with consumption of green tea. Compared to non-regular tea drinker, men consuming at least 300 g/month experienced reductions in their odds of developing colon cancer, rectal cancer, and pancreatic cancer by 18%, 28%, and 37%, respectively. For women, the respective reductions in the odds of those consuming at least 200 g/month were 33%, 43%, and 47%. As a result, it appears that green tea may, in fact, lower the odds of developing both colorectal and pancreatic cancers. (15)
