What are the four misunderstandings about drinking tea?
Myth 1: The fresher the tea, the better. New tea refers to new tea that has been fried with fresh leaves for less than half a month. Relatively speaking, this kind of tea really tastes better. However, according to the theory of traditional Chinese medicine, the freshly processed tea leaves have internal heat, and this internal heat needs to be stored for some time before it disappears. So drinking too much new tea will make people get angry. In addition, the content of tea polyphenols and caffeine in new tea is high, which is easy to stimulate the stomach. If you drink fresh tea often, you may have gastrointestinal discomfort. People with a bad stomach should drink less green tea that has been stored for less than half a month after processing. In addition, it should be reminded that not all tea leaves are new and better than the old ones. For example, black tea such as Pu 'er tea needs proper aging and better quality.

Myth 2: It is best to drink tea after meals. Drinking tea immediately after meals can easily lead to complex reactions between tea polyphenols in tea and iron and protein in food, thus affecting the absorption of iron and protein by human body. Drinking tea on an empty stomach before meals will dilute gastric juice and affect its secretion, which is not conducive to food digestion. The correct way is to drink tea at least half an hour after meals, preferably 1 hour later.

Myth 3: Tea can sober up. Drinking tea after drinking has advantages and disadvantages. 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 is helpful to hangover. But at the same time, this accelerated decomposition will increase the burden on liver and kidney. Therefore, people with poor liver and kidney had better not use tea to relieve alcoholism, especially don't drink strong tea after drinking.

Myth 4: Drinking tea before going to bed affects sleep. Caffeine contained in tea can excite the central nervous system, so it has always been said that drinking tea before going to bed will affect sleep. At the same time, caffeine is also a diuretic. Drinking plenty of water will inevitably increase the number of times you go to the toilet at night, which will affect your sleep. However, according to consumers, drinking Pu 'er tea has little effect on sleep. However, this is not because Pu 'er has less caffeine, but because of other reasons that are not clear at present.

Myth 5: Wash the tea, but you can't drink the first sip of tea. Whether you can have the first sip of tea depends on what kind of tea you drink. If it is black tea or oolong tea, it should be washed quickly with boiling water first, and then the water should be poured out, which can not only wash the tea, but also heat the tea, which is beneficial to the volatilization of tea fragrance. But green tea, black tea and so on. , don't need this process. Some people may be worried about pesticide residues on tea and want to remove pesticide residues by washing tea. In fact, the tea leaves used in the planting process are all water-insoluble pesticides, and there will be no pesticide residues in the tea soup. From the point of view of avoiding pesticide residues, it is unnecessary to wash tea.

Myth 6: It takes boiling water to make tea. High-grade green tea is generally brewed with water around 85℃, and overheated water is easy to reduce the freshness and refreshing of tea soup. Oolong tea such as Tieguanyin is best soaked in boiling water, and the tea smell is better; Pressed tea, such as Pu 'er cake tea, can also consider cooking tea, so that the characteristic quality components in Pu 'er tea can be fully leached.

Myth 7: The tea cover tastes delicious. When soaking tea and oolong tea, the lid is easier to make the tea fragrant, but when soaking green tea, the lid will affect the purity of the fragrance.

Myth 8: Make tea with paper cups or thermos cups. There is a layer of wax on the inner wall of the paper cup, which will affect the taste of tea after dissolution; The thermos cup sets a high temperature and constant temperature environment for tea, which will make the color of tea yellow, dark, bitter and stuffy, and even affect the health care value of tea. Therefore, when going out, it is best to brew with a teapot first, and then pour it into a thermos cup after the water temperature drops.

Myth 9: Make tea directly with boiling tap water. The hardness of tap water varies greatly in different regions. In tap water with hard water quality, the content of metal ions such as calcium and magnesium is high, which can react with tea polyphenols and other components in tea, thus affecting the aroma and taste of tea and the health care effect of tea. Comparatively speaking, it will be better to make tea with pure water.

Myth 10: Chewing tea residue after drinking tea helps to keep healthy. Some people will chew tea residue after drinking tea, because tea contains more nutrients such as carotene and crude fiber. But considering the safety, this method is not recommended. Because tea residue may also contain trace amounts of heavy metal elements such as lead and cadmium, as well as water-insoluble pesticides, if you eat tea residue, you will ingest these harmful substances into your body. Tea is used for drinking and eating. Both of them have different requirements for the limit of water-insoluble harmful substances. Drinking tea can use water-insoluble pesticides, which will not affect health, but chewing will have potential risks; The standard of eating tea is stricter.

In fact, in addition to the above misunderstandings, it should also be reminded that drinking hot tea, strong tea and overnight tea is not good for your health. If you want to keep healthy with tea, you'd better choose the right tea all year round. Drinking scented tea in spring helps to dispel the cold evil accumulated in winter; It is advisable to drink green tea in summer, because green tea can clear away heat and relieve summer heat and detoxify; It is advisable to drink green tea in autumn, namely oolong tea. This kind of tea is neither cold nor hot, which helps to eliminate the residual heat in the body, restore sweetness and warmth, and make people feel refreshed; Warm black tea or double fermented oolong tea should be drunk in winter.
