A recent animal study suggests that polyphenon E, a compound found in green tea extract limits the growth of colorectal tumors in rats.
According to results presented at the Sixth International Conference on Frontiers in Cancer Prevention, rats on a diet containing polyphenon E are less likely to develop colon cancer. The study shows polyphenon E decreases the number of malignant tumors per rat and the tumor size.
Findings reveal 67 percent of the rats on a normal diet developed malignant tumors while in the treated group the risk was about 27 percent.
In addition, tea polyphenols decreased the tumors per rat by 80 percent compared to the control group.
It should be noted that at the same conference, black raspberry gel and 'Blueberry Punch' (an antioxidant-boosted beverage) were reported to be effective in treating oral cancer lesions and prostate cancer.
