If green tea is your favorite form of caffeine, then I've got some great news for you. According to research presented at the Sixth International Conference on Frontiers in Cancer Prevention, green-tea extract may help to prevent colon cancer.
So far, the green-tea extract has been successful in fighting cancer in rats. When rats were fed a diet containing this extract, and then injected with tumor-causing azoxymethane (a chemical known to produce colorectal tumors that share many characteristics with colorectal cancer in humans), only 27 percent of the rats developed malignant tumors. Which is considerably lower than the rats who were not give green-tea extract – 67 percent of them developed malignant tumors.
The tumors found in the rats that were given the green-tea extract were also much smaller. When researchers examined those tumors, they found green-tea extract in them. This could be the start of using green tea in prevention and treatment of colon cancer in humans. Sounds like a great reason to sit back and enjoy a relaxing cup.
