End of winter and early spring, it is even more comfortable to drink a cup of hot tea when it is cold. But drinking tea has some small steps, so you must know! Drinking tea can not only achieve a refreshing effect, but also has the effect of preventing cardiovascular diseases.
Chinese doctor Chen Chaozong said that tea leaves have the effects of refreshing the mind, clearing heat and relieving heat, eliminating food and relieving phlegm, removing uterine and reducing fat, clearing the heart and eliminating dysentery, detoxifying and soothing alcohol, promoting fluid and quenching thirst, reducing fire and improving eyesight, stopping diarrhea and removing moisture. Especially in spring, it is prone to liver fire and in summer, it is prone to heart fire. You can drink mild green tea during the time period to help relieve liver fire and heart fire. However, people who usually have cold stomachs and eat a little cold food to get drunk, it is best not to drink green tea; the elderly recommend that Chenniansheng Pu'er tea be used instead of green tea.
Many studies show that tea leaves contain polyphenols, ketones and other antioxidants. Liu Pengchen, attending physician of the Department of Home Medicine at Xinguang Hospital, pointed out that these antioxidants have the effect of inhibiting blood fat elimination and can prevent middle wind, cardiovascular diseases, diabetes, etc. Among them, sarcophagus is the most studied, which is helpful for inhibiting the formation of fatty liver and reducing weight.
Green tea has the most teas, but don't drink it within an hour after the mealLiu Pengchen reminded that these studies are mostly animal experiments or basic research, and there is no actual human trial using "drinking tea". Therefore, how much tea should you drink and which tea should you drink? And there is no discussion. After all, the harvesting part of the tea leaves, the fermentation time of the tea leaves, the brewing time and the water temperature will affect the release of tea and other substances.
Generally speaking, unfermented tea, such as green tea, retains the most teas, but relatively speaking, unfermented tea has a higher content of nervoic acid, which can easily combine protein in the stomach, causing stomach discomfort. Therefore, it is not suitable for people with stomach diseases such as gastritis. In addition, monolactic acid also hinders the iron quality absorption capacity, so it is not recommended to drink green tea for one hour after the meal to avoid affecting the iron quality absorption.
Liu Pengchen said that in addition to sedica, polyphenols also include sedica gingivin and sedica gingivin, which are mostly found in fermented teas such as red tea or semi-fermented teas such as Ulong tea, and have antioxidant effects. People who cannot drink green tea may wish to choose red tea, Ulong tea, etc. for drinking.
It is worth noting that the proportion of caffeine in red tea is slightly higher. Taking 240 ml of tea as an example, the caffeine content of red tea is about 50 mg, Ulong tea is about 40 mg, and green tea is about 30 mg. However, it is necessary to note that the daily caffeine intake should not exceed 300 mg, especially those who sleep easily suffer from tea drinking should not drink too much.
The best time to drink tea From 9 to 11 amIn addition to drinking tea, there are also great questions about the time to drink tea. Chen Chaozong said that the best time to drink tea is between 9 and 11 in the morning, and the remaining time is enough to taste. The main reason is that the caffeine and tea sausage contained in tea have an exciting and diuretic effect. Therefore, it is recommended to drink less tea after 3 pm, and drinking tea at night can easily urinate too much at night, which will affect sleep.
Chen Chaozong suggested that drinking green tea after breakfast can help the spleen and stomach to dissolve, make the function of the five organs better and is beneficial to the rewards; drinking Ulong tea after lunch can lower blood lipids and promote gastric peristalsis, and help increase the ability of the stomach and kidney to empty.
Afternoon tea is suitable for drinking red tea. Chinese medicine believes that red tea is fermented tea. It has removed the slightly cold tea leaf by fermentation and oxidation. It can remove the characteristics of slight coldness of the tea leaf. It can remove moisture and warm the stomach and make the gas and blood clear. It is especially suitable for drinking in late winter and early spring. It can prevent the invasion of cold evil and has the effect of protecting the spleen and stomach.
