Green tea’s special properties
According to various health magazines and research, switching over to green tea can help you lose weight, reduce the risk of heart disease and cancer, or maybe even get pregnant.
Green tea and fertility
Green tea is made from fresh tea leaves, whereas black teas are made with fermented tea leaves. Green tea contains B vitamins and folate, which is natural folic acid. It also contains minerals, such as magnesium, caffeine, and antioxidants, such as polyphenols.
Polyphenols protect your body’s cells from damage that can lead to cancer and other diseases. They can also help to reduce inflammation and improve the flow of blood to the tissues in your body. Polyphenols may also affect fertility and ovulation, though experts don’t yet know whether the effects are all positive.
A balanced approach
Green tea clearly has some great health benefits. However, experts advise that people drink it in moderation. Firstly, green tea does contain caffeine, which should be avoided in excess. Secondly, a 2018 study at the University of California-Irvine researchers warn that excessive consumption of Green Tea may adversely affect fertility.
The study looks at the effect of green tea on the development and reproduction in fruit fly, and has not specifically tested the effects of green tea on human fertility.
It’s unclear whether overconsumption could have the same impact on humans, but the findings suggest caution when using green tea, or any natural product, in high doses.
“While green tea could have health benefits at low doses, our study and others have shown that at high doses, it may have adverse effects,”
Said Mahtab Jafari, associate professor of pharmaceutical sciences.
