How to drink tea correctly 1 incorrect way of drinking tea
1, after the tea is cold, heat the water and continue drinking.
Some people are used to heating the water to continue drinking after the tea is cold, and then heating the water halfway, so that the nutrients in the tea are difficult to dissolve and the fragrance is difficult to distribute. In addition, tea polyphenols, vitamins and protein will be oxidized and denatured, and harmful microorganisms will also increase.
Step 2 drink tea on an empty stomach
Drinking tea on an empty stomach will absorb more oxalic acid into the body, and the probability of forming stones is relatively high. Kidney calculi patients can drink water or lemonade to quench their thirst, because lemons contain a lot of sodium citrate, which can prevent kidney calculi.
Drink a lot of tea every day.
Ordinary healthy adults can drink 6 grams to 10 grams of tea a day and brew it two or three times.
Step 4 make tea with warm water
Because the beneficial chemical components extracted by warm water are not as sufficient as hot water, it is best to make tea with water at 70℃ ~ 80℃ first, and then drink it when the temperature drops to about 60℃. Don't exceed 70℃, Chata burns will cause strong irritation to the throat, esophagus and stomach, and cause mucosal lesions.
5. Drink the tea when it is cold.
After cooling, tea leaves contain a lot of oxalate, which will form small stones, block the ureter and increase the risk of kidney calculi.
Cut down on tea for five hours.
Never drink tea on an empty stomach, because tea will cool the spleen and stomach and get drunk easily.
It is not advisable to drink tea immediately before and after meals, because drinking tea before meals will dilute gastric acid, make the diet tasteless and affect the absorption function of digestive organs.
When drinking tea immediately after meals, tannic acid in tea will solidify with protein and iron in food, which will affect the absorption of protein and iron.
Tea should not be used instead of medicine, because tannic acid in tea will combine with many drugs to produce precipitation, which will affect the efficacy.
Drinking tea after drinking doesn't help hangover, it only hurts the kidneys.
The efficacy of drinking different teas
1, green tea protects cardiovascular system.
Green tea belongs to non-fermented tea, represented by West Lake Longjing, Dongting Biluochun and Huangshan Mao Feng. Its main function is to prevent cancer and cardiovascular diseases, and it also has the functions of antioxidation, improving immunity, inhibiting and killing bacteria.
2. White tea relieves anxiety
"White tea is classified according to different methods, including two kinds," said Han Chi. One is Anji white tea, which is familiar to everyone. It is actually a kind of green tea. Because it tastes more mellow than green tea, it is very popular in recent years. Jiang Heyuan said that the main function of white tea is to protect the brain, enhance memory and reduce anxiety. In addition, theanine in white tea can neutralize the effect of caffeine. "People who are afraid that drinking tea will affect their sleep can drink some white tea." There is also a kind of white tea produced in Fuding, Fujian. "This kind of tea produces less than ordinary green tea and tastes heavier. According to the current research, this kind of tea has a good effect of regulating immunity and lowering blood sugar, "Han Chi said.
3. Green tea and black tea lower cholesterol.
Green tea belongs to semi-fermented tea, and the representative varieties are Wuyi Rock Tea (Dahongpao), Tieguanyin, Frozen Top Oolong Tea, Fenghuang Danzong and so on. Black tea belongs to fully fermented tea, and its representative varieties are Qi Hong in Anhui and Dianhong in Yunnan. Black tea in India and Sri Lanka is also a world-famous brand. "Because of fermentation, black tea is less irritating than green tea and has different effects. It can promote blood circulation and lower cholesterol."
4. Pu 'er tea and black tea lose weight and fat.
Pu 'er tea and black tea belong to post-fermented tea, and people are most familiar with Pu 'er tea, in which the total amount of tea polyphenols is high, which has a good effect of reducing fat and losing weight. According to reports, Beenaert of Henri Rondo Hospital in Paris? Professor Giaccotto gives 20 patients with hyperlipidemia three bowls of Yunnan Pu 'er tea every day. A month later, he found that the patient's blood lipid almost decreased 1/4. According to Japan's "Health" magazine, Pu 'er tea can inhibit weight gain and reduce cholesterol and triglycerides in the blood.
How to drink tea is correct. 2. Tea that is not finished is the most likely to form tea scale.
Scientific research shows that drinking water contains minerals and trace harmful heavy metal ions, such as cadmium, mercury and arsenic. When water is heated, the solubility of some calcium and magnesium ions decreases and the concentration of insoluble salts increases with the increase of water temperature. When water is concentrated to a certain extent, it will precipitate out. These precipitates can be brewed with water and enter the cup. If tea leaves are not drunk or left in the air for a long time, tea polyphenols in tea leaves and metal elements in tea rust will be oxidized, resulting in tea rust, commonly known as tea scale, which adheres to the inner wall of the cup. Tea rust contains cadmium, lead, mercury, arsenic and other harmful metals, which is the chief culprit endangering human health.
Second, long-term use of cups without tea stains will cause cancer.
Li Zeng, an associate professor at Tianjin College of Medicine, said in an interview: "Tea scale contains toxic substances such as cadmium, lead, mercury and arsenic and carcinogens such as nitrite, which will adhere to the smooth surface of the teacup. As tea enters the body and human digestive system, it combines with protein, fatty acids and vitamins in food, resulting in insoluble precipitation, which not only hinders the absorption and digestion of these nutrients, but also damages organs such as the stomach. In addition, teacups that are often not cleaned have a lot of scale, which also contains a lot of heavy metals, which is extremely unfavorable to health. " At the same time, these oxides can also cause diseases and dysfunction of nervous system, digestive system, urinary system and hematopoietic system, and even cause premature aging, especially arsenic and cadmium can cause cancer, cause fetal malformation and endanger health.
Third, how to thoroughly wash away tea stains
The thicker the tea scale, the harder it is to clean, so daily cleaning is as important as regular cleaning. Experts suggest that after drinking tea every time, even if there is no obvious tea stain on it, the tea set should be carefully cleaned to avoid many a mickle makes a mickle.
1, tea scale is not easy to clean up after a long time. Soak in heated rice vinegar or baking soda for a day and a night, and then brush with a toothbrush, which is easy to clean. It should be noted that if you use a teapot, you don't need to clean it like this. The teapot itself has pores, and the minerals in the tea scale can be absorbed by these pores, which can not only maintain the teapot, but also prevent harmful substances from "running" into the tea and being absorbed by the human body.
2. Put a teaspoon of orange powder or orange juice in the teacup and teapot, fill it with clear water and let it stand for 2-3 hours, so that the tea scale loses its adhesion with the tea set and can be easily removed.
3. Add water to the teapot or teacup, add potato skin, heat it to boiling, cool it and rinse it, then you can easily clean it.
4. When the metal tea partition is used, it will turn black due to tea dirt. If it can't be washed off with a medium-sized cleaner, it can be soaked in vinegar or easily cleaned with bleach.
5. Coat it with edible salt, especially where there is tea dirt. Then scrub the teacup with a toothbrush, and finally rinse it with clean water.
Experts especially remind that it is best not to use rough cleaning tools such as steel balls and cleaning balls to clean tea stains, because these cleaning tools are easy to damage the enamel on the inner wall of the tea set, making it thinner and thinner, and the tea stains generated in the future are easy to penetrate into the deep layer of the tea set, which is extremely difficult to completely remove. Individuals should use a soft brush or toothbrush and a mild cleaning cloth to clean.
Fourth, make tea.
It is best to brew teabags only 1 time, and it is best to brew them in bulk in Chaze for more than 3 times.
How many times should tea be brewed before it is the most nutritious and healthy, except that the tea scale is not clear and harmful to the health? Many people don't know.
Some people in life like to make tea repeatedly until they can't taste it. Some people make tea once or twice and then change it quickly. Which of these two practices is correct, and how many times is it better to brew a cup of tea? Yin Junfeng, an associate researcher at the Tea Research Institute of the Chinese Academy of Agricultural Sciences, said that some people like weak tea, while others like strong tea. Although the times of making tea are closely related to different people's tastes, in terms of nutrient absorption, it is best to brew tea in bags only 1 time, and not more than 3 times in bulk in Chaze.
He explained that tea contains tea polyphenols with anticancer effect, tea polysaccharides that can lower blood sugar, caffeine that excites the central nervous system, amino acids, vitamins and other nutrients. How much these nutrients can be separated out has a great relationship with the number of times of brewing. Generally speaking, the larger the shape particles of tea, the slower the speed of nutrient precipitation; The smaller the particles, the faster the precipitation rate.
Compared with bulk tea, the leaves in bagged tea were cut and kneaded, the leaf cells were completely destroyed, and the particle shape was relatively small. After the first brewing for 3-5 minutes, 80%-90% of the nutrients in the tea will be precipitated, and after the second brewing, the remaining 65,438+00% of the nutrients will be almost completely precipitated. Therefore, Yin Junfeng suggested that it is best to brew bagged tea once, which not only has no loss in nutrient absorption, but also will not affect the taste and taste. Because the bulk tea particles are relatively large, the first brewing time is longer, which should be about 5 minutes, and 60%-80% of the nutrients will precipitate; After the second brewing, 80%-90% of the nutrients will be separated out. After the third brewing, the leaching rate of nutrients will exceed 95%. If you continue to brew, there will be no nutritional effect.
As for some experts, tea leaves will leach harmful substances such as pesticides and heavy metals after repeated brewing. Yin Junfeng said that although there is some truth in this statement, there is no need to worry too much. At present, most pesticides used in tea production in China are extremely low in water solubility. According to the calculation of 10g tea per person per day, even if 1mg/kg residual tea is brewed, the pesticide intake is only 0.000 1mg, which is one thousandth of the daily allowable intake stipulated by the World Health Organization. The leaching rate of heavy metal lead in tea is also low. As long as you buy tea from regular manufacturers, its content will not exceed the national standard.
Verb (short for verb) Drink tea.
12g per day is most suitable.
Jiang Heyuan, an associate researcher at the Tea Research Institute of Chinese Academy of Agricultural Sciences, suggested that ordinary people should drink about 12 grams of tea every day and brew it three to four times. People who eat more greasy food and have a large amount of alcohol and tobacco can appropriately increase the amount of tea. Pregnant women and children, neurasthenia, tachycardia, should be appropriate to reduce the amount of tea. Han Chi reminded that with the popularity of Kung Fu tea, people drink tea "more and more hot", which is very wrong. "People drink tea for health care, but drinking hot tea will increase the incidence of cancer such as esophageal cancer, which is not worth the candle. The best temperature for drinking tea should be about 60 C, not more than 70 C. "
In addition, you can drink different teas at different times of the day: drink a cup of light green tea in the morning to refresh your mind; Drinking jasmine tea in the morning has a pleasant fragrance and can improve work efficiency; Drink a cup of black tea in the afternoon to get rid of difficulties and refresh yourself; Getting together with friends or family at night and making a pot of oolong or Pu 'er will not affect sleep.
Six, the taboo of drinking tea
1, avoid drinking Leng Cha.
Many people often hear the old man say that Sanyo's things hurt you the most, that is, thin wine, Leng Cha, old woman. This shows how harmful it is to drink herbal tea.
Herbal tea has the side effects of cold coagulation and blood stasis, especially for women with cold body, so it is not suitable to drink herbal tea.
2. Avoid drinking tea on an empty stomach
Drinking tea on an empty stomach will not only lead to the dilution of gastric juice and the decline of digestive function, but also cause "tea drunkenness", which usually leads to dizziness, headache, fatigue, palpitation and even instability.
In addition, drinking tea on an empty stomach will aggravate hunger, and severe cases can cause hypoglycemia shock. Drinking tea on an empty stomach is tantamount to "inviting wolves into the room." There has been a saying in China since ancient times that "you don't drink hollow tea".
After getting up on an empty stomach or in the morning, you should drink a cup of boiled water first, then eat some snacks and then drink tea.
3. Avoid drinking tea before meals
Drinking tea before meals is about equal to drinking tea on an empty stomach. Drinking tea before meals will dilute saliva, make the diet tasteless, and temporarily reduce the function of digestive organs to absorb protein. Drinking tea on an empty stomach directly stimulates the gastrointestinal tract, which will dilute digestive juice, affect digestion and easily lead to tea drunkenness.
It is suggested that you can eat a little dessert or appetizer before drinking tea, and then drink tea, or you can drink tea while eating.
4. Avoid drinking tea immediately after meals.
It is not advisable to drink tea immediately after meals. Drinking tea immediately after meals will dilute gastric juice and affect food digestion. At the same time, tannic acid in tea will solidify the substances in food, increase the burden on the stomach and affect the absorption of protein.
It is best to drink tea one hour after meals, which can promote digestion and eliminate greasy.
5. Avoid drinking hot tea
Too hot tea irritates throat, esophagus and stomach. If you drink too hot tea for a long time, it may cause pathological changes in these organs. According to foreign research, people who often drink tea with a temperature over 62℃ are more likely to damage the stomach wall and suffer from stomach diseases.
How to drink tea is correct. In China, men, women and children like to drink tea on weekends. Some people even regard drinking tea as a habit, make a pot of tea slowly and enjoy the holiday leisure. However, not everyone is suitable for drinking tea for health, and not all teas can be drunk. Let's see under what circumstances we need to be isolated from tea.
1, avoid drinking overnight tea.
You'd better drink tea at once. Tea leaves have been stored for a long time, which not only leads to the loss of nutrients such as vitamins, but also tends to be rancid and sick.
2, avoid drinking the first sip of tea.
Because modern tea is inevitably polluted by pesticides, fertilizers, dust and other substances in the process of planting, processing and packaging. The first sip of tea is actually the water for washing tea, so it is necessary to rush into boiling water as soon as possible, so that the brewed tea is the most hygienic tea.
Drinking tea often can cultivate your self-cultivation, but these situations are not suitable for drinking tea. I hope everyone can pay attention to it. For your own health, you must avoid these situations when drinking tea.
3. Be careful when you are drunk.
Don't drink tea after drinking, tea has the function of exciting the nerve center, and drinking strong tea after drunkenness will increase the burden on the heart. Drinking tea will also accelerate diuresis, so that toxic aldehydes in alcohol will be discharged from the kidneys before decomposition, which is very irritating to the kidneys and harmful to health. Therefore, for people with heart disease or poor function, don't drink tea, especially don't drink a lot of strong tea; For healthy people, you can drink a small amount of strong tea. When you wake up, you can eat a lot of fruit or sip vinegar to speed up human metabolism and relieve drunkenness.
4. Don't drink tea on an empty stomach.
Drinking tea on an empty stomach will dilute gastric acid, inhibit the secretion of gastric juice, hinder digestion, and even cause palpitation, headache, stomach discomfort, dizziness, upset and other "drunken tea" phenomena, and affect the absorption of protein, but also cause gastric mucosal inflammation. If "tea drunkenness" occurs, it can be alleviated by taking candy or drinking some sugar water.
5. Take medicine with tea with caution
At present, there are many kinds of drugs with different properties, so it is impossible to generalize whether tea can replace medicine. Tannin and theophylline in tea can change chemically with some drugs. Therefore, when taking hypnotic sedative drugs, iron-containing blood-enriching drugs, enzyme preparation drugs, protein and other drugs, tea polyphenols are easy to react with iron and precipitate, so it is not appropriate to use tea to give drugs, so as not to affect the curative effect.
Some Chinese herbal medicines, such as Herba Ephedrae, Ramulus Uncariae cum Uncis, Rhizoma Coptidis, etc., should not be mixed with tea. It is generally believed that it is not advisable to drink tea within 2 hours after taking the medicine. When taking some vitamin drugs, tea has no effect on the efficacy, because tea polyphenols in tea can promote the accumulation and absorption of vitamin C in the human body. At the same time, tea itself contains a variety of vitamins. Tea itself also has the functions of excitement, diuresis, blood lipid reduction and blood sugar reduction, which can improve the efficacy of the human body and restore health. In addition, people often think that it is not appropriate to drink tea when taking tonic such as ginseng antler, which is also reasonable.
6. Avoid drinking a lot of tea before and after meals.
It is not advisable to drink tea for about 20 minutes before and after meals. If you drink tea, it will dilute the gastric juice and affect the digestion of food. Moreover, because tea contains oxalic acid, oxalic acid will react with iron and protein in food, which will affect the absorption of iron and protein by human body.
7. Avoid drinking tea before going to bed
It is best not to drink tea within 2 hours before going to bed. Drinking tea will make you feel high, affect your sleep and even insomnia, especially the newly picked green tea. After drinking, the nerves are extremely excited and cause insomnia.
8, malnutrition avoid drinking tea.
Tea has the function of decomposing fat. People who are already malnourished will be more malnourished if they drink tea to decompose fat.
9. Avoid drinking inferior or deteriorated tea.
Tea is not easy to keep properly, and it is easy to absorb moisture and become moldy, and some people are reluctant to discard moldy tea out of their love for saving tea. Deteriorated tea contains a lot of substances and germs harmful to human body, and it is absolutely inedible. If high-quality tea leaves are left for too long after soaking, the tea soup will also deteriorate due to oxidation and microbial reproduction, and such tea can no longer be drunk.
10, avoid drinking tea if you have a fever.
Caffeine in tea can not only raise the body temperature, but also reduce the efficacy.
How to drink tea correctly 4 After Tomb-Sweeping Day, spring tea came on the market one after another, indicating that spring is a good season for drinking tea.

Eat less herbal tea and drink scented tea appropriately. Drinking spring tea should focus on dispelling yin and cold, and promoting hair growth in spring.

However, because green tea belongs to non-fermented tea, the content of tea polyphenols is relatively high, which will also stimulate the stomach. Therefore, people with bad stomach should drink less, or drink less tea when brewing, so as to reduce the stimulation to the stomach. Female menstrual period, the mood is more agitated, drinking some scented tea is very suitable, which is helpful to regulate qi and menstruation.
Obese people who want to lose weight can drink more oolong tea, because oolong tea has a strong role in decomposing fat, which can help solve greasy and help digestion.
