Green tea has been consumed in China for more than 4,000 years and is one of the main products in the day of the people responsible for health.
Aside from the fact that we want to use it in our beauty routine, there has been a lot of research on green tea for years when it comes to its effect on cancer prevention. It was mostly about the so-called observational studies in which the researcher does not decide who will be exposed to the effect or therapy, but only observes data on the current condition.
The analyzed studies examined the association between green tea consumption and gastrointestinal cancer, gynecological cancers including breast cancer, urinary tract cancer including prostate cancer, lung cancer and oral cancer.
To study the effect of drinking green tea, researchers analyzed the drinking habits of 75,000 middle-aged and older Chinese women. They were asked if they drank tea, what kind they consumed and in what quantity. Most respondents said they mainly drank green tea.
Finally, experts concluded that women who drank tea at least three times a week for more than half a year had a 17% lower risk of developing all types of gastrointestinal cancer. Also, the degree of protection depends on the amount of tea drunk. Thus, women who drink two to three cups of tea a day, according to these results, can expect a 21% lower risk of cancer. The protective effect of tea was most evident when it came to stomach / esophageal cancer and colon cancer.
The researchers also took into account the lifestyle of the respondents: thus, smokers and people who drank alcohol were excluded from their analysis. Those who regularly drank tea were younger, exercised more, were more educated and ate more fruits and vegetables.
While we can not guarantee that it reduces the risk of cancer, green tea is definitely a better choice than juices that will dehydrate your body.
