Editor's Notes
- |good afternoon, i'm so glad to have chance to share some knowledge about Chinese tea culture with you. Thank Dr. Wang Liang 's invitation. I'm a gynecologic oncologist in Hunan Cancer Hospital, and also work in the International office of this hospital. I received Chevening scholarship of British government to support me studying at Queen's now. I'm not an expert at tea, but when i come to Belfast, i find many foreign friends are interested at Chinese tea, and even for some Chinese they are not familiar at this kind of knowledge, so let's study this together.
- first
- now, all Chinese medical staffs are fighting with the novel coronavirus now, one of my collegues died 3 days ago, because of high pressure work. hope this disaster will end soon.
- According to Lu Yu's Tea Classic, which is the first known monograph on tea in the world,
- Do you know how many kinds of Chinese tea are divided into?
- in china, according, but today i will not talk about the tea produce process.
- there are some famous green tea, you may have heard, such as
- most Bristish tea are kind of black tea, such as earl gray and English breakfast tea, but except black tea in it , there are also other ingredients in these tea.
- some dark tea are made looks like bricks
- i want to know for our foreign friends here who have been to China? Not only beautiful scenery, but also traditional Chinese culture and tea culture can be experienced
- ensure the taste of tea.
- different kind of tea , the water temperature is also different.
- already many researches show the reason tea consumption may provide protection against chronic diseases ,including cancer , hign blood pressure, hign cholest, is because tea contains polyphenols and amino acid, and the antioxidant activity of tea polyphenols has been implicated as a potential mechanism. tea contains polyphenols and amino acid has reached a consensus, but whether it can provide protection to these diseases, still need more researches.
- ignore Too many cups of tea a day can leave you dehydrated. Dr. Simran Saini, Nutrionist at Fortis Hospital in New Delhi, explains, "Excess ea consumption means excess consumption of caffeine. This can reduce the absorption abilities of your tubules, which can leave you dehydrated. I wouldn't recommend drinking more than three cups a day in any case." 2.Bloating Feeling bloated lately? May be you've drinking too much tea. The caffeine present in the tea may cause bloating in some people. Bangalore-based Nutritionist Dr. Anju Sood explains, "Excess consumption of tea may cause dehydration which calls for unwanted water retention and thus, you may feel bloated." 3. May Cause Vital Nutrient Deficiencies According to Dr. Simran Saini, "Excess consumption of tea may hinder absorption of essential nutrients like iron by the body." Some studies have shown that black tea may decrease the absorption of iron. 4. Can Get You Addicted One of the worst side effects of consuming excess tea is that you can easily get addicted to it. The caffeine in tea makes it addictive. Dr. Simran tells us, "When regular tea drinkers don't get their daily cup at the same time, it can leave them weary, lethargic, and irritable and bring down their energy levels." Some people may even experience headaches and fatigue until they get their daily quota of three to four cups of tea. 5.Anxiety and Restlessness Tea does help in boosting your energy levels and perking you up but excessive caffeine intake can take a toll on your mental health and make you feel more anxious, restless and even sleep deprived. Anything when consumed in excess will have its repercussions. If consumed in moderation, freshly brewed tea does offer some health benefits but you must bear in mind the side effects of tea.
- In traditional chinese medicine, People of different constitutions should drink different kind of tea.
- In xiangya medical school , there is Chinese Zen Tea course to cultivate the humanistic quality of medical students.
- in my hospital, tea culture lectures and tea art performances are hold regularly
- We also train and perform tea culture for patients.
