New research from the lab of Professor Mahtab Jafari reveals that excessive consumption of green tea adversely affects the development and reproduction of fruit fly populations. Professor Jafari and colleagues investigated the effects of high levels of green tea by subjecting fruit fly embryos and larvae to increasing doses of green tea polyphenols. Professor Jafari believes the mechanism behind their results could involve a triggering of excess cell death by the polyphenols. However, follow up studies will be needed to test this proposed mechanism.
At this point, its unclear whether overconsumption of the green tea polyphenols could have the same impact on humans. Professor Jafari’s findings suggest some caution when using green tea in high doses.
