The reason why you can't just drink tea without drinking water every day is because caffeine and other substances in tea have diuretic effect. If you drink tea as water, you may feel like "drinking water", but in fact, the water lost by your body is increasing.
So after drinking tea for a period of time, the frequency of going to the toilet will increase, and we often feel thirsty. When we are thirsty, we will continue to drink tea, and unconsciously our bodies will be in a state of water shortage.
As for how much tea to drink, first look at the numerical analysis. It is not accurate to measure by how many cups, because everyone's concentration is different, so let's calculate by the grams of tea.
There are mainly three functional components in tea, tea polyphenols, caffeine and theanine.
At present, there is no specific intake limit for tea polyphenols.
Because tea polyphenols are a mixture, it is composed of many components. As for the single ingredient in it, our daily intake is far from exceeding the standard.
The content of caffeine in tea is 1%~4%, and it is also found in coffee and cocoa, which is a familiar refreshing ingredient.
According to the EU Food Safety Agency, adults who consume less than 400mg of caffeine every day will not endanger health and safety.
In this way, if calculated according to the extreme maximum content (4%), it is not a problem to drink10g of tea (almost 3 cups of completely brewed tea) every day.
Theanine content in tea is 1%~2%, which has the functions of lowering blood pressure, calming nerves and avoiding excessive excitement. In the Announcement on Approving Tea Theanine as a New Food Raw Material (No.2014 15) issued by the state, it was pointed out that the maximum dosage was 0.4g ..
If calculated in this way, if the extreme maximum content (2%), it is not a problem to drink 20 grams of tea every day.
According to this result, it seems that 10g is safer. Of course, this is just a simple calculation. In the process of brewing, 65,438+0,000% of the contents of tea leaves will not be completely soaked out, and the absorption of the body will not be collected in sequence, and there will always be some loss in the process.
In addition, this calculation is based on the extreme maximum content. In fact, there will be no problem around 15g.
What is the concept of 15g? If it is the production method of congou tea, it is equivalent to three teas a day, and all of them are drunk by yourself until there is no taste. For most people, this is an unattainable number.
It should be noted that everyone's physical differences are different, just like drinking, some people are not drunk for thousands of cups, some people will faint after drinking one mouthful, and drinking tea is the same.
Therefore, it is very important to know your physical condition. It is recommended to replenish water consciously every day, and it is good to use about half and half tea.
If you really want to drink tea today, it doesn't matter if you drink too much. The human body has strong self-regulation ability. It doesn't mean that you are advised to drink 15g, but there is something wrong with drinking15.1g.
But if you feel dizzy and weak, your stomach is empty, and you are a little "drunk with tea", then your body is reminding you that you have drunk too much tea today, and it is time to stop and eat cookies and desserts for a while.
The Tea Department of Zhejiang University once suggested that the daily consumption of tea for adults is usually 5- 15g dry tea.
This is basically consistent with the above estimate. Most people who love tea drink in this range, so don't worry about exceeding the standard.
It doesn't matter if it exceeds a little occasionally. You only need to pay attention to whether you are unwell, but you can't drink strong tea for a long time.
As for Wuyishan, Chaozhou, Xishuangbanna and other places with strong tea drinking atmosphere and tradition, you may not drink much tea, but you are not feeling well, which is another matter.
