Green tea is often called healthy and is said to help prolong life. Scientists from the Swiss Higher
Green tea contains catechins called ECG andEGCG. It is claimed that they are what make tea attractive to everyone who wants to prolong life. These substances are considered antioxidants, which means they prevent oxidative stress in the body.
Until now, scientists assumed that catechinsneutralize free radicals and thus prevent damage to cells or DNA. However, now scientists have seen that these substances do not work that way.
Researchers have studied how catechins behave inworms C. elegans. As it turned out, these substances, on the contrary, contribute to oxidative stress. However, this effect is temporary. After short-term stress, the protective capabilities of cells and the body as a whole increase. As a result, the catechins in green tea were able to extend the life and improve the fitness of the worms. Sports and reducing calorie intake have a similar effect on the body.
The scientists said that the results of this studyare well tolerated in humans. However, they did not recommend drinking concentrated green tea. It is better to buy regular, herbal. Black tea contains less catechins. “This is why green tea is preferred over black tea,” the researchers concluded.
