Tea has been drinking for thousands of years, and as tea has gradually become an indispensable companion in people's lives, tea drinks have become one of the favorite beverage categories of Chinese consumers. There is an ancient proverb: seven things to open the door, firewood, rice, oil, salt, sauce, vinegar and tea. The Chinese's preference for tea can be seen from this. Brew a cup of tea, the taste is mellow and elegant, and the heart is relieved. However, liking tea does not mean that you can drink tea. Do you know all the following misunderstandings about drinking tea in life?
Myth 1: The fresher the tea, the better New tea refers to new tea that has been fried for less than half a month with fresh leaves, and this tea tastes really good. However, freshly processed tea leaves have a fire gas, which needs to be stored for a period of time before disappearing. In addition, the tea polyphenols and caffeine content in new tea are high, which can easily irritate the stomach. It is also important to note that not all kinds of tea are new and better than old, such as Pu'er tea and other teas that have better quality after aging.
Myth 2: It is best to drink tea immediately after a meal Drinking tea immediately after a meal is easy to cause a complexation reaction between the tea polyphenols in tea and the iron and protein in food, thereby affecting the body's absorption of iron and protein. If you drink tea brewed with 15 grams of dried tea leaves after a meal, it will reduce the body's absorption of iron in food by 50%, and in the long run, it will affect people's digestive function. In addition, drinking tea on an empty stomach before meals can also affect the secretion of gastric juice. The correct way is to drink tea at least half an hour after a meal, preferably 1 hour later.
Myth 3: Tea can sober up Drinking tea can accelerate the decomposition of alcohol in the body, and its diuretic effect can help the decomposed substances to be discharged, so it helps to relieve hangover. However, this accelerated decomposition will increase the burden on the liver and kidneys, and some people like to drink a large cup of strong tea to sober up when they are drunk, which does have a certain sobering effect, but drinking tea after drinking is also very harmful. Because after drinking, the heart is stimulated, the heartbeat is faster, and the brain is excited, and strong tea has the same effect, drunk tea is simply adding fuel to the fire to the heart.
Myth 4: Drinking tea before going to bed affects sleep The caffeine contained in tea has the effect of stimulating the central nervous system, so it has always been said that drinking tea before going to bed will affect sleep. But in fact, drinking tea at night does not necessarily mean insomnia, the key depends on what tea you drink and how you drink it. Many teas with a high degree of fermentation, such as black tea and ripe Pu'er tea, have little caffeine left in them, and will hardly affect sleep, so drinking some tea to help digestion an hour after dinner can clear the stomach and help sleep.
Myth 5: Tea leaves need to be washed and made to make tea, but you can't drink tea Whether you can drink tea depends on what kind of tea you drink. If it is black tea or oolong tea, it should be quickly washed with boiling water first, and then the water should be poured out, which can not only play the role of washing tea, but also warm the tea, which is conducive to the volatilization of tea aroma. But green tea, black tea, etc., do not need this process. Some people may be concerned about pesticide residues on tea leaves and want to remove pesticide residues by washing tea. In fact, the tea is planted with water-insoluble pesticides, and there will be no pesticide residues in the tea soup used to make tea, so it is not necessary to wash tea from the perspective of avoiding pesticide residues.
Myth 6: Boiling water should be used to make tea High-grade green tea is usually brewed with water about 85 °C, overheated water makes the soup fresh and refreshing, boiling water to make tea will destroy vitamins and other active ingredients, aromatic oil volatilizes a lot, tannic acid, theophylline is also leached in large quantities, the nutritional value of tea is reduced, harmful substances increase, the tea taste loses its aroma, and the appropriate water temperature for making tea is between 80~90 °C. But it should also depend on the quality of the tea, the tea is tender, the water temperature should be lower, the old water temperature of the tea can be appropriately higher, and the tea should be brewed and drunk, the tea is brewed for 3~5 minutes, and the tea slowly sinks to the bottom of the cup, and you can drink it slowly while it is hot. The first cup of tea can not be drunk, you need to leave one-third, to be brewed again, generally tea, brew two to three times, until the tea is light and tasteless. Tea like Tieguanyin is best brewed in boiling water. Pu-erh cake tea can also be considered to boil tea, so that the characteristic ingredients in Pu-erh tea can be fully leached.
