Green Tea Reduces the Number of Lung Tumors in Lab
Animals
Study description: As part of a larger
study on lung cancer, lab animals were injected with a cancer-causing substance.
They were then divided into two groups and were given either green tea water (solution of 0.6% green tea)
or plain water as their sole source of drinking fluid for the next 20 weeks,.
Type of study: Animal
What happened: After the 20-week experimental
period, the animals were sacrificed and their lungs were examined. The researchers
found that those that had received green tea water had approximately half as
many tumors as those that had received plain water.
Researchers' comment: There was a "significant
reduction in tumor multiplicity" (number of tumors per animal) among the animals given green tea water.
