Drinking tea reasonably is beneficial to human body, but if it is unreasonable, it will be harmful to human body. Check whether you have made these mistakes when drinking tea! [Recommended reading] Diet appropriateness and taboos
◆ Tea can be divided into coolness and warmth through different production processes. People with hot and dry constitution should drink herbal tea, while those with deficient and cold constitution should drink warm tea.
It is best to drink black tea at night. Because green tea belongs to non-fermented tea, it has high content of tea polyphenols and strong irritation; Black tea is a kind of completely fermented tea with weak irritation. Especially for people with weak spleen and stomach, adding some milk when drinking black tea can play a certain role in warming the stomach.
◆ People who are easily excited or sensitive, have poor sleep and are weak should drink less or not drink tea at night.
◆ When drinking tea at night, put less tea and don't make the tea too strong. It's best to drink after meals. Drinking tea on an empty stomach can easily inhibit the secretion of gastric juice, hinder digestion, and seriously cause palpitations, headaches and other "tea drunkenness" phenomena.
Eight common mistakes in drinking tea
I like drinking new tea.
Because of its short storage time, new tea contains more unoxidized polyphenols, aldehydes, alcohols and other substances, which has a strong stimulating effect on human gastrointestinal mucosa and is easy to induce stomach diseases. Therefore, drink less new tea and avoid new tea that has been stored for less than half a month.
Second, drinking tea for the first time
Because tea is polluted by harmful substances such as pesticides in the process of planting and processing, there will always be some residues on the surface of tea, so the first-time tea should be discarded because of its washing function.
Third, drink tea on an empty stomach.
Drinking tea on an empty stomach will dilute gastric juice, reduce digestive function, increase water absorption rate, and lead to a large number of bad components in tea entering the blood, causing dizziness, palpitation, weakness of hands and feet and other symptoms.
Fourth, drink tea after meals.
Tea contains a lot of tannic acid, which can react with iron in food to form new substances that are difficult to dissolve. Over time, it will cause iron deficiency and even induce anemia. The correct way is to drink tea an hour after meals.
Five, have a fever to drink tea.
Tea contains theophylline, which can raise body temperature. Drinking tea for patients with fever is tantamount to "adding fuel to the fire".
Six, patients with ulcers drink tea
Caffeine in tea can promote gastric acid secretion, increase gastric acid concentration, induce ulcers and even perforation.
Seven, drinking tea during menstruation
Drinking tea during menstruation, especially strong tea, will induce or aggravate menstrual syndrome. Medical experts have found that compared with people who don't drink tea, people who have tea habits are 2 or 4 times more likely to have menstrual tension than those who don't drink tea, and those who drink more than 4 cups a day are 3 times as likely as those who don't drink tea.
Eight, unchanged
The climate is different all year round, and the types of tea should be adjusted accordingly. It is advisable to drink scented tea in spring, which can disperse the cold evil accumulated in the body all winter and promote the hair growth of human yang; It is advisable to drink green tea in summer. Green tea tastes bitter and cold, and it can clear away heat and relieve summer heat, detoxify, enhance gastrointestinal function, promote digestion, prevent diarrhea and skin boils infection. Green tea should be drunk in autumn. Green tea is neither cold nor hot, which can completely eliminate the residual heat in the body, restore sweetness and warmth, and make people feel refreshed; It is advisable to drink black tea in winter, which is sweet and rich in protein and has a certain nourishing effect.
Correct brewing method of green tea
1, when brewing green tea, the water temperature should be controlled at about 80℃ ~ 90℃. If green tea powder is brewed, it can be brewed with warm water of about 40℃ ~ 60℃. The serving size is 2g of green tea powder and 450ml of boiled water.
2. Don't drink the first time you make tea. After pouring hot water, shake it and pour it out.
3. The brewed tea should be drunk within 30 minutes to 60 minutes, otherwise the nutrients in the tea will become unstable.
4, green tea powder can not be soaked too thick, otherwise it will affect the secretion of gastric juice, it is best not to drink on an empty stomach.
Drinking tea and health II. Advantages and disadvantages of drinking tea
1, the benefits of drinking tea regularly:
(1) Drinking tea can help you lose weight.
Tea contains catechins, cholesterol ketone, caffeine, inositol, folic acid, pantothenic acid and other components, which have the function of preventing and inhibiting obesity under the comprehensive action.
(2) Tea can prevent cardiovascular diseases.
Drinking tea can also reduce cardiovascular diseases such as hypertension and cholesterol.
(2) Drinking tea can prevent tooth decay.
Drinking tea or brushing your teeth with tea can not only eliminate bad breath, but also prevent dental caries. Since 1970s, we have been studying the efficacy of tea in preventing dental caries, such as drinking tea, gargling with tea soup, brushing your teeth, or using toothpaste containing tea, but brushing your teeth with tea soup is the best. This is because tea contains fluorine, which has great affinity with calcium in teeth and can become a kind of "neon apatite" which is difficult to dissolve in acid.
(4) Tea is a good medicine for intestinal diseases.
Polyphenols in tea can solidify and precipitate protein. Tea polyphenols combined with single-celled bacteria can coagulate eggs and kill bacteria. If harmful cholera, typhoid and Escherichia coli are soaked in strong tea soup for a few minutes, most of them will lose their mobility, which is good for preventing intestinal infectious diseases.
2. The disadvantages of drinking tea often
(1) Drinking strong tea is easy to cause constipation.
Tannic acid in tea can not only combine with iron, but also with protein in food, forming a large amount of tannic acid protein, which is difficult to digest and absorb, leading to constipation. For the elderly with constipation, constipation will be more serious.
(2) affecting normal digestion
The normal gastric juice secreted by a person every day is 1, 5-2, 5 liters, which can reasonably digest the food that a person takes in every day. When drinking a lot of strong tea, it will dilute the gastric juice, reduce the concentration of gastric juice, make the gastric juice unable to digest food normally, and cause indigestion, abdominal distension, abdominal pain and other symptoms, and some even cause duodenal ulcer.
(3) Tea hinders the absorption of iron by human body.
Tea contains tannic acid, black tea contains about 5%, and green tea contains about 10%. When people drink a lot of strong tea, the combination of tannic acid and iron will be more active, which will bring obstacles and influence to the absorption of iron and cause iron deficiency anemia.
(4) Strong tea leads to hypertension and heart failure.
Caffeine in strong tea can make the human heart beat faster, thus raising blood pressure; At the same time, a large amount of strong tea liquid enters the blood vessels, which can increase the burden on the heart, produce discomfort symptoms such as chest tightness and palpitation, and aggravate the degree of heart failure.
Everything is measured. Drinking light tea can keep you healthy, while drinking strong tea is harmful to your health.
Drinking tea and health. What kinds of tea are better in light tea?
Light tea is just to put less tea according to your own preferences. You can put two kinds of tea, Biluochun or Dahongpao, which is the best of the light teas.
1, "Biluochun"
Biluochun is a traditional famous tea in China and one of the top ten famous teas in China. It belongs to the category of green tea and has a history of 1000 years. Biluochun is also called "Biluochun in Dongting" because it is produced in Dongting Mountain and Dongting Mountain in Taihu Lake in Wuxian County, Suzhou City, Jiangsu Province.
It was listed as a tribute in the Tang Dynasty, and the ancients also called Biluochun "Kung Fu Tea" and "New Blood Tea". The high-grade "Biluochun" tea buds are delicate, and 0.5 kg of dry tea needs 60,000-70,000 tea buds. After frying, the dried tea strips are tightly knotted, with exposed white hairs, silvery green color, attractive jadeite and curled into snails. It was produced in spring, hence the name "Biluochun". This tea is a famous tea in China. The white clouds in the cup are rolling and the fragrance is overflowing. The main processes are enzyme fixation, kneading, kneading to show off details, and frying.
2. Dahongpao
Dahongpao, produced in Wuyishan, Fujian, is an excellent oolong tea. China famous tea. Its shape is compact, the color is green, brown and fresh. After brewing, the soup color is orange and yellow, and the leaves color is red and green. The most outstanding quality is rich fragrance, orchid fragrance, high and lasting fragrance, and obvious "rock rhyme"
Dahongpao is very resistant to foam, and it still smells after being soaked for seven or eight times. When drinking "Dahongpao" tea, you must drink it slowly with a small pot and a small cup of "congou", so that you can truly taste the charm of Zen tea on top of rock tea. Pay attention to live, sweet, clear and fragrant.
3. The art of making tea
Starting with a piece of tea, as long as it is not fake tea, there is no problem with workmanship and the tea is well preserved. This is a kind of tea worth making. The rest depends on how we interpret the essence of this tea through brewing.
Specifically, the direction of our efforts is to give full play to the "advantages" of this tea in our hands and block the "disadvantages" as much as possible to prevent it from being released. How do we do this? Sun Tzu's Art of War says: Know yourself and know yourself, and you will be invincible.
To understand the advantages and disadvantages of a kind of tea, we must think about the "tea characteristics" of this kind of tea during the brewing process. Starting with tasting, we should try our best to master the method of tasting and try our best to understand it from three aspects: "tea fragrance, tea taste and tea rhyme". Then the thinking analysis method in the process of product identification will guide us to continuously improve the quality of the next brewing.
