Is drinking green tea really good for your health?

July 4, 2019 news / BIOON / - green tea is a popular health trend, many people drink green tea to hope to benefit from it There's nothing wrong with that, nutritionists say Green tea is a healthy drink rich in antioxidants But many of its so-called health benefits have yet to be determined Photo source: Nancy Farrell Allen, a registered dietician at https://cn.bing.com in Fredericksburg, Virginia, said: "clinical trials related to green tea are still at an early stage I said drink it and enjoy it It won't hurt, and there may be benefits worth drinking But nutrition is a science, and it takes time for us to understand "The potential health benefits of green tea come from catechins, a powerful antioxidant known as flavonoids, said ChElSEY Schneider, director of clinical nutrition at the Israel cancer center in Sinai, New York One of the catechins in green tea, EGCG, is higher than in white or black tea, she said "This compound can be even stronger than vitamins C and E, which are very, very powerful antioxidants," Schneider said "Antioxidants help prevent cell damage "Green tea, black tea and white tea all come from the same plant," Allen said "Photo source: https://cn.bing.com green tea is made from leaves of mature plants, while white tea is made from leaves picked in early development Black tea, she said, is made from green tea leaves covered with a wet cloth "They dry, they turn black, and they ferment a little bit to make the black tea darker and stronger," Allen said "But this process also reduces the content of catechins in black tea Green tea is linked to weight loss, according to a study by the Department of nutrition at the University of California, Davis Experts say that green tea contains caffeine and catechins, which can promote the metabolism and processing of fat But the University of California, Davis, says people seem to have to drink a lot of green tea to get substantial weight loss benefits, and pay attention to other aspects of their diet Green tea is also linked to heart health For example, a study of more than 80000 Chinese published in the Journal of the American Heart Association in 2018 showed that green tea can reduce "bad" LDL cholesterol Researchers at the University of California, Davis, say there is evidence that catechins in green tea can also reduce the risk of heart attack, help blood vessels relax and reduce inflammation Green tea can even reduce the risk of certain cancers The American Cancer Society says research shows that green tea can reduce the risk of ovarian cancer The University of California, Davis, says the model suggests that green tea may reduce the risk of many other cancers Photo source: https://cn.bing.com but a 2016 evidence review by Cochrane Library concluded that "there is not enough evidence to make any definitive recommendations on the prevention of cancer by drinking green tea "Schneider said the study was limited "Some small studies have shown that green tea may have a preventive effect on some cancers, such as breast cancer, ovarian cancer, endometrial cancer, pancreatic cancer and oral cancer, but there are not so many solid human trials to support this view," she said "Green tea may also help keep your brain younger A 2014 study published in the journal PLoS One found that Japanese people who drank more green tea had significantly less brain dysfunction, although the researchers could not rule out the possibility that these people might have other healthy habits that help keep their minds sharp One warning of all these studies is that it often happens in Asian countries, where people drink more green tea It could be a big difference for Americans Schneider added that the way you drink green tea may reduce any potential positive impact "A lot of people add processed sugar to their green tea, which really turns something beautiful and healthy into something unhealthy," she said "It's not a good idea to add milk or cream to your tea "There are studies that show that adding milk to green tea actually stops you from absorbing the antioxidant effect," Schneider said If it was me, I would drink it directly "Reference materials: [1] is green tea a fad or a real health boost [2] Xiang Gao et al Tea consumption and digital change in high ‐ density lipoprotein selective concentration in Chinese adults Journal of the American Heart Association 2018; 7 Doi: https://doi.org/10.1161/jaha.118.008814 [3] moeko noguchi-shinohara et al Consumption of Green Tea， but Not Black Tea or Coffee， Is Associated with Reduced Risk of Cognitive Decline PLOS ONE 2014 DOI：https：//doi.org/10.1371/journal.pone.0096013
