Cancer prevention by tea and tea polyphenols.
The inhibition of tumorigenesis by tea extracts and tea polyphenols has been demonstrated in different animal models, including those for cancer of the skin, lung, oral cavity, esophagus, stomach, small intestine, colon, bladder, liver, pancrease, prostate, and mammary glands. Caffeine is also active in inhibition of tumorigenesis on the skin, lung, and perhaps other organs. In spite of many in...

متن کاملGreen tea polyphenols in the prevention of colon cancer.
Several plant-based nutrients and non-nutrients that can inhibit mutagenesis and proliferation have been identified. Some of the most promising nutrients identified as chemopreventive agents in colon cancer prevention include isoflavones, curcumin, calcium, vitamin D and more recently Green tea polyphenols (GTP). In addition to inhibiting mutagenesis and proliferation, these compounds are relat...
