A study which was published in the Journal of Functional Foods found out that drinking the antioxidant-rich beverage, green tea, may impair your ability to reproduce. The researchers examined the effects of the tea on development and reproduction of fruit flies. They were exposed to fly embryos and larvae to different doses of the tea’s antioxidants, polyphenols. The larvae exposed to this antioxidant were slower to develop, emerged smaller and exhibited a dramatic decline in the number of emerged offspring. They were more prone to dehydration due to polyphenols, but became more sensitive to starvation and heat stress.

Polyphenols were also found to negatively impact the reproductive organs in males and females, like a dearth of mature eggs in females and atrophic testes in males.

The information from the study showed that high doses of GTP adversely affect development and reproduction of fruit flies.

Why does this matter for people?

The research group of Mahtab Jafari at the University of California, Irvine, explored ways to increase the human lifespan. According to them, fruit flies make an ideal model system for studying aging as they share 75% of the human gene’s diseases in people. Moreover, they mimic certain aspects of human psychology like the tendency to become imbalanced after the consumption of too much alcohol.

Green tea provides health benefits at lower doses, but in higher doses, it may have adverse effects. Scientists have to make further work in order to make definite recommendations. They suggest you drink green tea in moderation as then it will provide with health benefits, but not excessively drinking it.

Other researches on green tea

According to some researches, green tea promotes longevity and is able to fight health issues like cancer, heart disease, and Parkinson’s disease as well. There is polyphenols and flavonoid named epigallocatechin gallate in green tea, and they both have antioxidant properties. Another research said that this tea promotes cellular DNA and membrane structural integrity due to the antioxidant activity which protects the cells from oxidative damage. Another benefit from green tea is that it contains L-theanine which boosts the immune system, has a role in the metabolism and relaxing, and also has anti-anxiety effects. Some researchers have doubts that green tea will bring about our demise any time soon, because, even though fruit flies share 75% of the same genes we have, it is hard to explore information and make case for effect on human health when the subject group is actually fruit flies.

Moreover, 10 mg of green tea, which is the amount to which the experimental group was exposed to, is actually a massive amount for such species of that size, while for a human being to consume that amount will be pretty unlikely to have such an effect.

Certainly, we need more research in order to know how this tea impacts people’s health. Some scientists recommend drinking this tea once a day to experience the antioxidant benefits.
