Your Daily Dose of Green Tea can Actually be Harmful to Your Health, Study Finds
Hailed as one of the most health beneficial drinks, green tea has been known and used for centuries. But a study has found out that if it is consumed in large amounts, the beverage could do more harm than good to one's health.
In conducting the study, the researchers used fruit flies as their test subjects to observe how excessive intake of green tea can damage the reproductive function and how their offspring would develop.

Fruit flies were chosen as subjects since they share 75 per cent of the same genes that would usually cause the disease in humans.
Although the said experiment wasn't able to clearly point out if green tea would have the same effects on humans. Experts say the results of the study should serve a heads up to everyone who consumes a lot of green tea and other available nutraceuticals in the market.
Previous research involving animal studies showed that too much consumption of green tea can actually induce adverse weight loss and impaired development processes.
Moderate consumption of green tea
Together with his colleagues, Mahtab Jafari, an associate professor of pharmaceutical sciences at the University of California-Irvine, who led the study, exposed embryos and larvae of fruit flies to various green tea dosages in order to reach their findings.
They found out that almost 10 milligrams of green tea resulted in a slower rate of development of the larva. Also, a surprising reduction with regards to the number and size of offspring was also noted. Due to the of green tea, some physical abnormalities in the reproductive organs of the fruit flies were also discovered.
Although green tea is known to be the primary defense of flies against dehydration, it increases their vulnerability to starvation and heat stress.
