A study conducted by Chinese researchers suggests that drinking three cups of tea a day could be the key to slowing down the aging process. The research was published in the journal Lancet Regional Health.
Researchers studied the presence of healthy substances found in black and green tea. According to them, these substances have the ability to “positively influence aging” by reducing cell damage and enhancing organ function for a long time.
The greatest benefits have been observed in individuals who maintain a consistent tea drinking habit. However, research suggests that even those who are not accustomed to it can improve their health by adopting this daily practice.
Yi Xiang, from Sichuan University (China), commented on the results on the portal the sun. “We have found that consuming approximately three cups of tea daily can provide anti-aging benefits. This can be attributed to the fact that tea contains many bioactive substances.
Previously, other studies indicated that drinking tea can reduce the chances of developing diabetes and heart disease.
Tea is known to contain polyphenols, which are powerful antioxidants that also play a role in protecting against cancer and neurological diseases such as dementia.
Thus, Xiang explained that tea contains several bioactive substances, such as polyphenols, theanine and caffeine, which may be related to its potential anti-aging effects.
“Polyphenols, in particular, have been identified as modulators of the gut microbiota, which may play a critical role in regulating age-related changes in immunity, metabolism and cognitive function,” he added.
Understanding the study on tea
The researchers analyzed data from 5,998 adults in the United Kingdom, aged 37 to 73 years, and 7,931 people in China, aged 30 to 79 years. Thus, the scientists surveyed the amount and type of tea consumed, including green tea, oolong tea (blue tea) and black tea.
In this way, they measured biological aging through special blood tests that examine changes in people's DNA.
The results showed that the speed of aging decreased with any amount of alcoholic beverages consumed during the average follow-up period, which lasted two years. Furthermore, according to research, improvements peaked when three cups were consumed daily.
