Words: "Seven things to open the door, rice, oil, salt, sauce and vinegar tea." China people can't live without tea. Tea is the most familiar drink for people.
drinking tea is good for your health, but only if you drink the right tea.
Modern medicine believes that the secret of tea health lies in the components such as tea polyphenols, tea pigments and tea polysaccharides. How to hold these beneficial ingredients when drinking tea?
key 1: tea brewing time
it is best to soak for 4-6 minutes before drinking, and the beneficial components in tea can be basically separated out.
key 2: times of making tea
Generally, black tea and green tea are brewed 2-3 times, and oolong tea and black tea are brewed 3-5 times. Soaking for too long is not healthy.
key 3: don't make tea upside down
the first tea of green tea and black tea contains about 7%~8% beneficial ingredients.
To drink tea healthily, we must adhere to the principle of "two noes":
Do not drink tea on an empty stomach: drinking tea on an empty stomach may lead to excessive caffeine absorption, and may cause discomfort such as palpitation and frequent urination.
don't drink tea for 3 minutes after meals: so as not to affect the digestion and absorption of food.
In addition, we should remind everyone that tea contains caffeine, which can excite the central nervous system. Don't drink too much strong tea at one time. In addition, caffeine can also promote gastric acid secretion, so people with more gastric acid secretion should be cautious when drinking tea, and it is best to drink lighter tea.
Tea is one of the healthy drinks recommended by China Nutrition Society. Tea drinking has a long history in China, and it is also the birthplace of world tea culture.
In addition to basic nutrients, tea also contains chemical components beneficial to human body, such as tea polyphenols, caffeine and tea polysaccharides. Active substances such as tea polyphenols and catechins can keep blood vessels elastic, eliminate arterial vasospasm and prevent blood vessel rupture. Studies have shown that drinking tea for a long time may be beneficial to prevent cardiovascular diseases and some tumors. Therefore, drinking tea regularly and in moderation is beneficial to health.
Everyone's physique is different, and their health status is also different, so we should pay attention to drinking tea. If we drink it correctly, it will be beneficial to our health. If we follow the trend blindly, it will be disadvantageous. Then how to drink tea can fully reflect its health to human body?
First, choose the type of tea according to your own situation
Tea can be divided into fermented tea, semi-fermented tea and non-fermented tea according to the degree of fermentation during processing. According to the color of tea, it can be divided into green tea, black tea, black tea, green tea and white tea. Why should we mention the types of tea? Because different kinds of tea have slightly different effects on the body, such as green tea, which belongs to non-fermented tea, tea polyphenols and other ingredients are kept high and cool, so it is more suitable for men, people with body heat, obesity, hyperactivity of liver yang, hypertension and so on. Black tea belongs to fermented tea, and the water-soluble tea polyphenols remain at about 5%-55%. It is the most enzymatically oxidized tea, which is mild in nature, so it is more suitable for women and people with cold body. Oolong tea belongs to semi-fermented tea, with a significant increase in ether effluents, which can be used by ordinary people and is more suitable for people with beauty, refreshing and cardiovascular diseases, and so on.
Second, choose the amount and time of drinking tea
The amount of drinking tea should not be too strong. Drinking strong tea for a long time will affect the digestive function, and tannic acid in tea will hinder the absorption of iron and protein, especially for people with iron deficiency anemia and malnutrition. Because drinking tea contains caffeine, people with insomnia should not drink tea before going to bed. So as not to aggravate insomnia. Drinking tea on an empty stomach will dilute gastric juice, reduce digestive function, and affect appetite and digestion and absorption. So remember, don't drink tea on an empty stomach and before going to bed.
Third, the temperature of drinking tea should not be cold
Tea leaves are bitter and cold, so it is advisable to drink hot tea. Drinking cold tea will hurt the spleen and stomach. Especially for those with weak gastrointestinal digestive function and weak constitution, drinking Leng Cha is even worse.
Fourth, choose the type of tea according to the seasonal changes
In spring, when all flowers bloom, the earth recovers and the human body grows yang, you can choose to drink scented tea to soothe the liver and relieve depression. The weather is hot and hot in summer. In order to clear away heat and relieve summer heat, you can choose green tea to drink. In autumn, the air is crisp and the temperature difference between morning and evening is too large. It is best to drink black tea to avoid stomach cold and bloating.
Fifth, choose the type of tea according to the age group
In the young and middle-aged period, the human body has strong metabolism and strong absorption of nutrients, so green tea should be the best. In old age, because the spleen and kidney function tend to decline, black tea and scented tea are suitable.
Sixth, choose the correct method of making tea
Although the tea ceremony in China is more particular, the temperature of tea selection, water and cups are very important. But I won't introduce them one by one here. Let's sum up what is suitable for the public: The correct way to make tea is to cool the boiling water slightly (about 9%) and pour it into a pot or cup. The tea can be drunk after 5 minutes. But you can't drink it dry at one time, but you should keep 1/3 of the tea as the bottom, so that you can maintain a certain concentration after continuous drinking.
ok. You can choose the tea that suits you according to the above points, which will help your health.
tea culture has a long history in our country.
There are many friends who like drinking tea at ordinary times, which can not only cultivate sentiment, but also contribute to physical and mental health. In that case, what good will tea do us? What kind of tea is the most beneficial to health?
Next, let Xiaokang introduce you! First, the common benefits of drinking tea
1. Anti-aging
Tea leaves are rich in tea polyphenols, which have antioxidant and physiological activities, and can be used to remove harmful excessive free radicals from human body, reduce active enzymes and play a role in delaying aging.
2. Prevention and treatment of radiation
Tea polyphenols and oxidation products in tea are helpful for absorbing some radioactive substances. Therefore, drinking tea often can play a good role in preventing and treating radiation injury.
3. Reducing blood fat and helping digestion
Because tea contains an ingredient called caffeine, it can be used to increase the secretion of gastric juice, thus enhancing the ability to decompose fat, which can help digestion and reduce fat.
4. Diuretic relieving fatigue
Caffeine in tea is beneficial to stimulate the kidneys, help the urine to be excreted quickly, enhance the filtration rate of the kidneys and reduce the retention of harmful substances. Not only that, tea can also eliminate excessive lactic acid in urine, which helps to eliminate fatigue. Second, how to drink tea is healthier?
Although drinking tea can bring many benefits, if we don't use the right method when drinking it, it may be counterproductive and inhibit its nutritional value.
note 1 for drinking tea: how many times is it better to brew a cup of tea?
Many friends usually don't pay attention to the times of brewing when drinking tea, which may often lead to the loss of nutrients.
generally speaking, it is advisable to brew black tea, green tea and scented tea three times. Oolong tea has a large amount of leaves when brewing, and the tea leaves are coarse and old, so it can be brewed several times. Teabag made from black tea is usually suitable for one-time brewing. Besides, the ideal way to make a drink is to have a cup of tea in the morning and evening, which is the most beneficial to the body and mind.
note 2: drinking tea in four seasons can be different!
according to the different seasons, our choices of drinking tea are also different.
Generally speaking, drinking scented tea in spring, green tea in summer, green tea in autumn and black tea in winter is better for human health. Because drinking scented tea in spring can promote the occurrence of human yang. It is better to drink green tea in summer, which can clear away heat, relieve summer heat, detoxify, quench thirst and strengthen the heart. It is better to drink green tea in autumn, which can eliminate the residual heat in the body and restore body fluid. Drinking black tea in winter can help digestion, replenish the body and make the body strong.
Precautions for drinking tea 3: Tea drinkers should be careful!
As we all know, tea contains a variety of nutrients, such as vitamins and amino acids, which can produce a variety of nutritional values for human body. However, this does not mean that all people are suitable for drinking tea.
It is not suitable for patients with neurasthenia, insomnia, hyperthyroidism, tuberculosis, heart disease, gastropathy and intestinal ulcer to drink tea, and it is also not suitable for lactating and pregnant women and infants to drink more tea.
well, that's all about healthy tea drinking. I hope everyone can carefully taste the cup of fragrant tea in their hands, and gain sweetness and health at the same time!
Kang Aiduo pushes all kinds of professional and interesting health knowledge for you every day to help you see through health rumors and get out of the misunderstanding of medication!
Tea is a national drink, and the tea drinking culture of China people can be traced back thousands of years. Although it is well known that drinking tea is good for people's health, every good thing has two sides, and drinking tea is no exception. Of course, drinking tea scientifically is the purpose of achieving health.
Drink tea in moderation:
Drinking tea is not "the more the better", but in moderation. Drinking too much tea, especially strong tea, is very harmful to health. Because the caffeine in tea will make the central nervous system of human body overexcited, the heartbeat will be accelerated, the burden on the heart and kidney will be increased, and sleep will be affected at night. High concentration of tea and polyphenols are easy to combine with metal ions in human gastrointestinal tract, which will affect the absorption of iron, calcium and other minerals in food. High concentrations of caffeine and tea polyphenols can also stimulate the stomach, inhibit the secretion of gastric juice, and affect digestive function.
The reasonable amount of tea drinking is determined by many factors, such as drinking habits, age, health status, living environment, customs and so on. Adults should drink 5~15g of dry tea every day. For manual workers, people who exercise a lot, consume a lot and eat a lot, especially those who are exposed to toxic substances in high temperature environment, don't drink more than 2g of tea every day. People who eat meat as their staple food, or people who eat more greasy food and smoke, can also increase the consumption of tea appropriately, and also do not exceed 2g every day. For pregnant women, children and those who are weak or suffer from neurasthenia, iron deficiency anemia, tachycardia and other diseases, it is recommended not to drink tea.
Reasonable tea drinking time:
We should also consider the appropriate drinking time when drinking tea. Tea has a refreshing effect, and drinking tea in the morning and afternoon can improve work efficiency. Drinking tea before and after meals will dilute gastric juice, affect the digestion of food and possibly affect the absorption of nutrients in food, so 1 hour after meals is the best time to drink tea. Also, it is not recommended to drink tea before going to bed at night. After drinking tea, urine output will increase, and caffeine in tea will also affect sleep.
Don't drink hot tea:
Tea is made with hot water, but when we drink tea, we should try to wait until the tea is a little cooler. Because the tea soup with high water temperature is easy to burn the oral cavity, throat and esophageal mucosa, long-term high temperature stimulation will also cause organ lesions, such as oral cavity and esophageal tumors. Studies have also shown that frequent drinking of tea soup with a temperature of more than 62 degrees will cause stomach problems when the stomach wall is damaged. Then the suitable temperature for drinking tea is about 56 degrees.
Finally, it is suggested that women in physiological period should not drink tea, and it is also not suitable for drinking tea during medication.

Many people have the habit of drinking tea, and think that drinking tea is healthier. But do you know that if you drink tea incorrectly, you will also get into cancer? Do you know these precautions for drinking tea?
Precautions for drinking tea
1. Don't drink overheated tea
Research shows that eating overheated food and drinks for a long time is one of the high-risk factors of esophageal cancer. If the temperature of tea is 65.69, the risk of esophageal cancer will increase greatly, and the temperature of tea will exceed 7, and the risk of esophageal cancer will even increase by more than 8 times. Therefore, to avoid drinking overheated tea, the temperature of tea is between 56 and 6.
2. Pay attention to pesticide residues in tea
If there are pesticide residues in tea used for making tea, it will also have an impact on health. In addition to buying tea from reputable merchants, you can pour out the first brewed tea when making tea, and open the lid when making tea, so that some pesticide substances will evaporate with water vapor.
3. How much tea to drink a day is appropriate
The amount of tea to drink depends on drinking habits, age, health, living environment, customs and other factors. Generally healthy adults, if they have the habit of drinking tea at ordinary times, drink about 12 grams of tea every day, and it is best to brew it three to four times. For manual workers, especially those with a large amount of labor, high temperature environment and more exposure to toxic substances, you can drink about 2 grams of tea every day. Pregnant women, children, neurasthenia, tachycardia and other people, the amount of tea should be appropriately reduced.
4. How to drink tea for patients with gastric diseases
Patients with gastric diseases should not drink tea when taking medicine. After taking medicine for 2 hours, they can drink some black tea, milk black tea, etc., which is helpful to diminish inflammation and protect gastric mucosa, and also has certain effect on preventing and treating ulcers. The components in tea can also block the formation of nitroso compounds and prevent precancerous lesions.
5. Whether diabetic patients should drink more tea
Sugar friends are characterized by elevated blood sugar, dry mouth, thirst, fatigue, etc. Drinking tea can effectively lower blood sugar, and at the same time have the effects of quenching thirst and strengthening physical strength. Sugar friends can generally drink more green tea, and the amount of tea can be slightly more, so that the effective components of tea can maintain sufficient concentration in the body.
6. Choose tea that suits you
Choose tea according to your physique and needs. For example, people with hot physique can drink more green tea, people with bad stomach can choose fermented tea, and people with poor digestion can drink Pu 'er tea to help digestion.
In addition, we should also pay attention to the quality of tea when choosing tea. If the tea is poor, it is either bitter or astringent, so it is best not to drink it. Such tea is easy to spoil the stomach.
besides the scientific brewing method, we should also pay attention not to make tea with moldy tea, not to drink fasting tea, not to drink overnight tea, and not to drink strong tea before going to bed. Generally speaking, it is better to drink new tea, but some old teas also have health care effects, such as old black tea and old Pu 'er, which are very effective in maintaining the stomach. Can drinking tea really keep you healthy?
many people should have heard of drinking tea for health. Actually,
