How to drink tea is the healthiest
Making tea is learned.
Main points of making tea
To really get a good cup of tea, you need good tea, good water, good tea set and good tea-making technology. Tea brewing technology includes three elements: tea consumption, tea temperature and brewing time.
There is no uniform standard for how much tea to use each time when making tea. Stapler depends on the type of tea, the size of tea set and the drinking habits of consumers. There are many kinds of tea. Different kinds of tea have different dosage. Brew ordinary red green tea, put about 3g dry tea in each cup, and add 150-200ml boiled water; If you drink Pu 'er tea, put 5- 10g per cup. Oolong tea is the most used tea, and each input is 1/2-2/3 of teapot.
For advanced green tea, especially all kinds of famous teas with delicate buds and leaves, it is not suitable to brew with 100 degree boiling water, but generally it is appropriate to brew with 80 degree water (referring to cooling after brewing with boiling water), so that the brewed tea soup must be light green and bright, with fresh taste, and less damage to vitamin C in tea. All kinds of scented tea, black tea and low-grade green tea should be brewed with 100 degree boiling water. If the water temperature is low and the permeability is poor, the effective components in tea will be less leached and the tea taste will be light. Soaking oolong tea, Pu 'er tea and Tuocha requires a lot of tea leaves every time, and because the tea leaves are thick and old, they must be brewed with 100 degree boiling water. Sometimes in order to maintain and improve the water temperature, it is necessary to heat the tea set with boiling water before brewing, and pour the boiling water out of the pot after brewing.
How many times should I make tea?
The bubble resistance of tea is not only related to tenderness, but also depends on the processing method of tea. When the tea leaves are chopped at the beginning, the tea juice is easy to brew, and the speed of brewing rough, old and complete tea leaves is slow.
No matter what kind of tea is brewed for the first time, the leaching amount accounts for 50% ~ 55% of the total soluble matter; Secondary brewing generally accounts for about 30%; The third time is about10%; Only 1% 3% for the fourth time. Judging from the nutritional components (vitamins and amino acids in tea), 80% was leached in the first brewing, about 15% in the second brewing, and almost all of them were leached after the third brewing. The aroma and taste of tea have a strong tea fragrance and a fresh and refreshing taste; Second, although tea is rich, it tastes as fresh as ever; Third, the aroma and taste of tea have faded; If you brew it again, it will be tasteless.
Ordinary black tea, green tea and scented tea should be brewed 3 times. When oolong tea is brewed, the leaves are large and the tea leaves are coarse and old, so it can be brewed many times. Teabags made of black tea are usually suitable for one-time brewing. It is not advisable to make a cup of tea from morning till night. After repeated brewing, tea can gradually leach out some insoluble harmful substances (such as some trace pesticide residues), which is harmful to human body. The most ideal way to make tea is to have a cup of tea every morning and a cup of tea in the afternoon, which is both fresh and fragrant.
Drink tea correctly.
There is a difference between drinking tea in four seasons.
Tea drinking pays attention to the four seasons, namely: scented tea in spring, green tea in summer, green tea in autumn and black tea in winter. The reason is that people who drink scented tea in spring can emit the cold evil accumulated in the human body all winter, and the rich fragrance can promote the occurrence of human yang. In summer, drinking green tea is better. Green tea tastes bitter and cold, which can clear away heat and relieve summer heat, detoxify and quench thirst, and strengthen the heart. In autumn, drinking green tea is better. This kind of tea is neither too hot nor too cold, which can eliminate residual heat in the body and restore body fluid. Drinking black tea in winter is ideal. Black tea is sweet and warm, rich in protein, which can help digestion, tonify the body and strengthen the body.
Drink 2 ~ 6 grams of tea every day.
Although tea contains a variety of vitamins and amino acids, drinking tea can relieve boredom, enhance nerve excitement and promote digestion and diuresis, but not the more you drink, the better, and not everyone is suitable for drinking tea. Generally speaking, 65438+ 0-2 times a day, 2-3 grams each time, is more appropriate. It is not suitable for patients with neurasthenia, insomnia, hyperthyroidism, tuberculosis, heart disease, gastropathy and intestinal ulcer, nor for lactation period, pregnant women and infants.
Don't drink too strong tea.
Strong tea will make the "excitability" of human body too high, which will have adverse effects on cardiovascular system and nervous system. Patients with cardiovascular diseases may have tachycardia or even arrhythmia after drinking strong tea, which leads to repeated illness.
Don't drink tea before going to bed.
This is more important for early tea drinkers. After drinking tea before going to bed, it becomes very difficult for many people to fall asleep, which even seriously affects their mental state the next day. People with neurasthenia or insomnia should pay special attention.
Don't drink a lot of tea while eating.
Drinking a small amount of tea before or during meals is not a big problem, but if you drink a lot of tea or drink too much tea, it will affect the absorption of many macro elements (such as calcium) and trace elements (such as iron and zinc). Pay special attention not to drink tea at the same time when drinking milk or other dairy products. Theophylline and tannic acid in tea will combine with calcium in dairy products to form water-insoluble calcium salts, which will be excreted, greatly reducing the nutritional value of dairy products.
Drinking too much tea is not good for digestion.
Tea contains a lot of tannic acid. Once it is combined with protein, a kind of food in meat, eggs and seafood, it will slow down intestinal peristalsis, which will not only easily cause constipation, but also increase the possibility of toxic or carcinogenic substances being absorbed by the human body.
Green tea and medlar can't be drunk together.
Green tea and Lycium barbarum can be brewed and drunk with boiling water respectively, which is very beneficial to human body. Many people simply put them together to brew. However, a large amount of tannic acid contained in green tea has convergence and adsorption effects, which will adsorb trace elements in Lycium barbarum and produce substances that are difficult for human body to absorb. Therefore, experts suggest: drink green tea in the morning to stimulate appetite and refresh your mind; Drinking Lycium barbarum in the afternoon can enhance physical fitness and have a good sleep.
Drinking tea hurts your health.
After drinking, the alcohol in the wine enters the blood through the gastrointestinal tract and is converted into acetaldehyde in the liver, which is then converted into acetic acid, which is then decomposed into carbon dioxide and water to be discharged. After drinking tea, theophylline in tea can quickly diuretic the kidney, thus promoting the undecomposed acetaldehyde to enter the kidney prematurely. Acetaldehyde has a great stimulating effect on the kidney, so it will affect the renal function. People who often drink strong tea after drinking are prone to kidney disease. Not only that, the ethanol in wine is very irritating to the cardiovascular system, and tea also has the effect of exciting the heart. The combination of the two enhances the stimulation to the heart, so drinking tea for heart patients is more harmful.
Tea is not as fresh as possible.
From a nutritional point of view, the freshest tea is not necessarily the best, because the so-called new tea refers to the tea that has been picked for less than one month. Because these tea leaves have not been placed for a period of time, some substances that have adverse effects on the body, such as polyphenols, alcohols, aldehydes, etc., have not been completely oxidized. If you drink new tea for a long time, you may have discomfort such as diarrhea and bloating. Too fresh tea is even worse for patients, such as some people with gastric acid deficiency or elderly patients with chronic gastric ulcer, which is even more unsuitable for drinking new tea. New tea will stimulate their gastric mucosa, cause gastrointestinal discomfort and even aggravate their condition.
