1, the misunderstanding of drinking tea
Myth 1: The more expensive the tea, the better.
The price of tea is determined by quality and grade. Quality mainly refers to the origin and tree species of tea, and the grade is mainly related to the picking time and location. The prices of tender buds, one bud and one leaf, and one bud and two leaves vary greatly. The same is Longjing, and the tea picked before Qingming is the most expensive. Wang Qing, executive vice president of China Tea Circulation Association, believes that people actually don't need to buy high-grade tea, but can choose according to their personal economic ability and different tastes. 100—300 yuan can buy very good quality tea at the price of one catty. I suggest that you pay more attention to quality rather than grade when buying. Some high-grade teas are picked too early and tender, and some of the nutrients are in the stalks, while some cheap teas have better health care effects.
Myth 2: 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 3: 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 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. In fact, many highly fermented teas, such as black tea and cooked Pu 'er, have little caffeine residue and will not affect sleep. On the contrary, drinking digestive tea an hour after meals can clean the stomach and help you sleep.
Myth 5: 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 6: Wash 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.
Myth 7: Drink a cup of tea all day.
It is not advisable to soak a big teacup and a handful of tea leaves a day, so that the real taste of tea can not be tasted, and it is easy to precipitate heavy metals in tea leaves for a long time, which is not good for your health. Tea must be separated from water when drinking tea. Even if there is no professional tea set, you can prepare a teapot or teacup with a strainer.

2. resist ultraviolet rays. Tea polyphenols are water-soluble substances. Washing your face with tea can remove greasy face, astringe pores, have the functions of disinfection, sterilization and anti-aging, and also help to reduce the damage of ultraviolet rays in the sun to the skin. It is a natural "sunscreen".
3. Stay in shape. The discussion on tea in Compendium of Materia Medica in the Tang Dynasty once mentioned that "eating for a long time makes people thin", which was confirmed by the Institute of Modern Science. Caffeine in tea can promote the secretion of gastric juice, help digestion and enhance the body's ability to decompose fat. Foreign studies also show that drinking tea regularly can reduce waist circumference and body mass index (BMI), thus helping to prevent diabetes and cardiovascular and cerebrovascular diseases.
4. Radiation resistance. Foreign studies show that tea polyphenols and their oxides can absorb some radioactive substances, protect cells from radiation damage and help repair damaged cells. Clinical research shows that tea extract can treat mild radiation sickness caused by radiotherapy in tumor patients, and treat hemocytopenia and leukopenia caused by radiation with good effect.
5. Improve memory. Tea polyphenols contribute to local brain adjustment, improve memory and improve learning efficiency. Foreign studies have confirmed that drinking tea can prevent and treat nervous system diseases, especially the cognitive impairment of the elderly. In addition, caffeine can stimulate the central nervous system, which has the functions of refreshing, benefiting the heart and clearing the heart.
6. Improve bone density. Although tea contains caffeine, it will promote the loss of calcium with urination, but the content is extremely low. Even black tea with high caffeine content is only 30~45 mg per cup. In fact, tea contains more substances that can help reduce calcium loss, including fluorine, phytoestrogens and potassium. A study in Taiwan Province found that people who drink tea regularly have higher bone density and lower probability of hip fracture.
