Saying: "Seven things to open the door, rice, oil, salt, sauce and vinegar tea." People in China can't live without tea. Tea is the most familiar drink.

Drinking tea is good for health, but only if you drink the right tea.

Modern medicine believes that the secret of tea health lies in tea polyphenols, tea pigments, tea polysaccharides and other ingredients. How to grasp these beneficial ingredients when drinking tea?

Key 1: tea making time

It is best to soak for 4~6 minutes before drinking, and the beneficial components in tea can basically be separated out.

Key 2: the number of times to make tea.

Generally, black tea and green tea are brewed 2~3 times, and oolong tea and black tea are brewed 3~5 times. It is unhealthy to soak for too long.

Key 3: Don't pour tea.

The first tea of green tea and black tea contains about 70%~80% beneficial ingredients.

Drinking tea healthily must adhere to the principle of "two noes";

Don't drink tea on an empty stomach: drinking tea on an empty stomach may lead to excessive absorption of caffeine, causing discomfort such as palpitation and frequent urination.

Don't drink tea for 30 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 a 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 light tea.

Tea is one of the healthy drinks recommended by China Nutrition Society. China has a long history of drinking tea and is also the birthplace of world tea culture.

Because tea contains not only basic nutrients, but also chemical components beneficial to human body, such as tea polyphenols, caffeine, tea polysaccharides and so on. Active substances such as tea polyphenols and catechins can keep blood vessel elasticity, 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 in moderation is good for your health.

Everyone's physique is different, and their health status is also different, so drinking tea is still particular. Proper drinking is good for health. If you blindly follow the trend, you will suffer.

So how to drink tea can fully reflect its health effects on the 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 mention the kind 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 remain 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 50%-55%. It is the tea with the highest degree of enzyme oxidation and mild nature, so it is more suitable for women and people with cold body. Oolong tea belongs to semi-fermented tea, and the ether effluent is obviously increased, so it can be drunk by ordinary people, and it is more suitable for people with beauty, refreshing and cardiovascular diseases.

Second, choose the amount and time of tea.

The amount of tea should not be too strong. Drinking strong tea for a long time will affect the digestive function. 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 is bitter and cold, so it is advisable to drink hot tea. Drinking herbal tea will hurt the spleen and stomach. Especially for people with weak digestive function and weak constitution, drinking herbal tea is even worse.

Fourth, choose the kind of tea according to the seasonal changes.

In spring, flowers bloom, the earth recovers and the human body is yang. You can choose to drink scented tea to soothe the liver and relieve depression. It 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 fresh, and the temperature difference between morning and evening is too great. It is best to drink black tea to avoid stomach cold and bloating.

Fifth, choose the type of tea according to the age group.

Among young adults, the human body has strong metabolism and strong absorption of nutrients, and green tea should be the best. In old age, because the spleen and kidney function tend to decline, black tea and scented tea are both suitable.

Sixth, choose the right way to make tea.

Although the tea ceremony in China is exquisite, the temperature, water and cups are very important. But I won't introduce them one by one here. Let's sum up the practice suitable for the public: the correct way to make tea is to cool the boiling water slightly (about 90%) and pour it into a pot or cup. Tea can be drunk after 5 minutes. But you can't drink it all at once, and you should leave 1/3 tea as the bottom, so that you can maintain a certain concentration after the water is replenished.

All right. You can choose your own tea according to the above points, which is helpful to your health.

Tea culture has a long history in China.

Many friends like to drink tea in peacetime, 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 it to you!

First, the common benefits of drinking tea

1, delaying aging

Tea is rich in tea polyphenols, which have antioxidant and physiological activities. Can be used for eliminating harmful excessive free radicals in human body, reducing active enzymes and delaying aging.

2. Prevention and treatment of radiation

Tea polyphenols and oxidation products in tea help to absorb some radioactive substances. Therefore, drinking tea regularly can play a good role in preventing radiation damage.

3. Reduce blood fat and help 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 bring the effect of helping digestion and reducing fat.

4, diuretic to relieve fatigue

Caffeine in tea can stimulate the kidneys, help urine to be excreted quickly, enhance the filtration rate of 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 tea, it may be counterproductive and inhibit its nutritional value.

Precautions for drinking tea: How many times is it better to brew a cup of tea?

Many friends usually drink tea without paying attention to the number of times of brewing, which often leads to the loss of nutrients.

Generally speaking, black tea, green tea and scented tea should be brewed three 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. In addition, the most ideal way to mix wine is to have a cup of tea in the morning and evening, which is most beneficial to the body and mind.

Precautions for drinking tea 2: Drinking tea in four seasons can be different!

According to different seasons, we have different choices for drinking tea.

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 and relieve summer heat, detoxify and quench thirst, and strengthen the heart. It is better to drink green tea in autumn, which can eliminate residual heat in the body and restore body fluid. Drinking black tea in winter can help digestion, replenish the body and make it strong.

Precautions for drinking tea three: people who drink tea 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 the human body. However, this does not mean that all people are suitable for drinking tea.

Patients with neurasthenia, insomnia, hyperthyroidism, tuberculosis, heart disease, stomach disease and intestinal ulcer should not drink tea, and it is not advisable for pregnant women and infants to drink more tea during lactation.

Well, that's all about healthy tea drinking. I hope everyone can savor the cup of fragrant tea in their hands and harvest 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 China people's tea drinking culture can be traced back to thousands of years ago. 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 to achieve the goal of 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 your health. Because caffeine in tea will make the central nervous system of the human body excessively excited, the heartbeat will be accelerated, the burden on the heart and kidneys will be increased, and sleep at night will also be affected. High concentrations of tea and tea polyphenols are easy to combine with metal ions in human gastrointestinal tract, which will affect the absorption of minerals such as iron and calcium in food. High concentrations of caffeine and tea polyphenols can also stimulate the stomach, inhibit the secretion of gastric juice, and affect digestive function.

Reasonable tea consumption is determined by many factors, such as drinking habits, age, health status, living environment, customs and habits, etc. Adults should drink 5~ 15g 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 20g of tea every day. People who eat meat as their staple food, or people who eat greasy food and smoke more, can also increase the consumption of tea appropriately, and the same amount should not exceed 20g per day. For pregnant women, children and people who are weak or suffering from neurasthenia, iron deficiency anemia, tachycardia and other diseases, it is recommended not to drink tea.

Reasonable tea drinking time: when drinking tea, we should also consider the appropriate drinking time. 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 may also affect the absorption of nutrients in food, so 1 hour after meals is the best time to drink tea. Also, drinking tea before going to bed at night is not recommended. After drinking tea, urine volume will increase, and caffeine in tea will also affect sleep.

Don't drink hot tea: tea is brewed with hot water, but when we drink tea, we should try to wait until the tea is a little cooler. Because tea soup with high water temperature is easy to burn 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 drinking tea soup with a temperature above 62 degrees often damages the stomach wall, which will cause stomach problems. Then the suitable temperature for drinking tea is about 56 degrees.

Finally, it is suggested that women should not drink tea during physiological period, and it is not suitable for drinking tea during medication.

Many people have the habit of drinking tea and think it is healthier. But do you know that drinking tea incorrectly can also lead to cancer? Do you know these precautions for drinking tea?

Matters needing attention in drinking tea

Don't drink overheated tea.

Studies have shown that long-term consumption of overheated food and beverages is one of the high-risk factors for esophageal cancer. If the temperature of tea is 65 69, the risk of esophageal cancer will increase greatly, and if the temperature of tea exceeds 70, the risk of esophageal cancer will even increase by more than 8 times. So avoid drinking overheated tea, the temperature of tea is between 56-60.

2. Pay attention to pesticide residues in tea.

If there are pesticide residues in the tea used when 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 should I drink a day?

Tea consumption depends on drinking habits, age, health status, living environment, customs and other factors. Generally healthy adults, if they have the habit of drinking tea, drink about 12 grams of tea every day, and it is best to brew it three or 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 20 grams of tea every day. Pregnant women, children, neurasthenia, tachycardia and other people, the amount of tea should be reduced appropriately.

4. How do stomach patients drink tea?

Patients with gastropathy should not drink tea when taking medicine. They can drink some black tea, milk black tea, etc. 2 hours after taking the medicine, which is helpful to diminish inflammation and protect gastric mucosa, and also plays a certain role in preventing and treating ulcers. The components in tea can also block the formation of nitroso compounds and prevent precancerous lesions.

5. Should diabetics drink more tea?

Sugar friends are characterized by high blood sugar, dry mouth and thirst, and fatigue. Drinking tea can effectively lower blood sugar, and at the same time play a role in quenching thirst and enhancing 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 the tea that suits you.

You should choose tea according to your physique and needs. For example, people with hot constitution 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, when choosing tea, we should also pay attention to the quality of tea. If the tea is poor, not bitter or astringent, you'd better not drink it. Such tea is easy to spoil the stomach.

In addition to scientific brewing methods, we should also be careful not to use moldy tea to make 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 functions, such as old black tea and old Pu 'er, which are very effective in nourishing the stomach.

Can drinking tea really keep you healthy? Many people should have heard of drinking tea to keep fit. In fact, can drinking tea definitely strengthen the body? Not necessarily! Not all tea is good for your health. If you don't pay attention to the way you drink tea, it will bring some side effects to your health.

What kind of tea to drink and how to drink it can have the effect of health preservation?

The first is choice. Do you choose tea that is comfortable after drinking or tea that satisfies the taste buds? Although good tea will taste good, good tea is not necessarily good for your health. New tea drinkers can easily go into a misunderstanding if they don't know how to feel with their bodies.

From Shennong Baicao to Compendium of Materia Medica, many ancient books have the function of recording tea, which is known as the "medicine for all diseases" and enters the five meridians of heart, liver, spleen and kidney. Tea does contain a variety of compounds, including more than 30 kinds of amino acids, as well as a variety of vitamins, tea polysaccharides, minerals and so on.

But while tea has so many effects on the body, it can also cause irritation to the body. If the tea you drink for a long time is not clean and not suitable for your physique and living habits, this kind of stimulation will gradually accumulate and cause harm to your body.

If you want to keep healthy by drinking tea, you must have a rational cognition and expectation of the efficacy of tea.

Although there are many substances in tea that are beneficial to health, its greatest effect lies in detoxification. Therefore, for people with poor metabolism and detoxification function, it is most obvious to improve their physical condition by drinking tea.

One of the ways to test whether a tea has any effect on your health is to keep drinking it for a period of time (2 weeks to a month). During this period, your life schedule and diet should not change too much, and try to maintain a normal life schedule.

Then observe whether your excretion has changed, whether it has become smooth, regular and stable (this method itself can be ignored).

If these reactions are all there, and even the appetite becomes very good, it can be proved that this kind of tea has a good influence on the body at present. If the excretion is getting worse and worse, it is getting more and more chaotic (it should be normal for the first two weeks to be more and more irregular), don't drink it.

There are many ways to judge whether a tea is suitable for you, except the above. However, these methods need to do a lot of concrete situation analysis, which can not be explained clearly in a few paragraphs.

At present, it is judged from the perspective of traditional Chinese medicine. For example, people with cold body suggest drinking warm tea, while those with hot body suggest drinking tea.

In modern society, due to the popularity of air conditioners, the use of refrigerators, the reduction of manual labor and the frequent intake of cold drinks, most people are cold.

Among the six major teas, warm teas include oolong tea, black tea and black tea.

Is it better to choose warm tea to drink? That's not necessarily true.

Now consumers are really tired ... For example, Tieguanyin belongs to oolong tea now, but it is herbal tea.

Due to the change of modern tea-making technology and the drive of interests, it is more in line with the demand of capital to reduce production costs and make tea with good aroma.

How to drink tea is the best for your health?

After choosing your favorite tea, how to drink fragrant tea and drink tea healthily is also a science. "Different teas have different methods of preservation, brewing and drinking."

Preservation: Tea is most afraid of moisture, mildew and odor. The best preservation containers are tin bottles, porcelain jars and colored glass bottles. Secondly, choose tin cans, wooden cases, bamboo boxes, plastic bags and cartons. The container should be dry, odorless and clean. Tea containers should be placed in dry and ventilated places, not in damp, high temperature, unclean and exposed places for a long time. Camphor, medicine, cosmetics, cigarettes, washing products and other irritating items should not be placed in the tea container at close range. The new green tea of that year is sealed and put into the freezer of the refrigerator for 3-6 months.

Brewing:

The longest tea washing time cannot exceed 15 seconds. "There are voices that advocate washing tea to filter impurities, but I don't agree with excessive washing tea." Some professionals said that in the experiment, it was found that the leaching rate of nutrients in green tea was above 70%, and that in black tea was above 60%. If tea leaves must be washed, the washing time should not exceed 15 seconds. Green tea and white tea, it is best not to wash. "But there is one exception. People who are sensitive to caffeine should wash it before drinking tea. Caffeine is leached faster than tea polyphenols, and quick washing can remove some caffeine. "

Drinking:

12 grams of tea per day is the most suitable. For ordinary people, it is advisable to drink about12g of tea every day and brew it for 3-4 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, children, neurasthenia and tachycardia should drink less tea. Professionals remind that with the popularity of kungfu tea, the trend of drinking tea is "getting hotter and hotter", which is not good for human body. "Drinking tea is health care, but the temperature of drinking hot tea will increase the incidence of cancer such as esophageal cancer. The best temperature for drinking tea should be about 60 degrees, and it is best to control it within 70 degrees. "

Tea is a traditional drink in China. Tea contains a lot of tannic acid, theophylline, caffeine and a small amount of aromatic oil, chlorophyll, vitamins and other nutrients. Moderate drinking tea can strengthen the heart, quench thirst, eliminate dampness and reduce fever, eliminate diseases and clear the body, which is of great benefit to human health. So how to drink tea to be healthy?

First, choose the right tea.

Because the function of tea is different, the choice of tea is different. For example, black tea nourishes the stomach, green tea refreshes, oolong tea reduces weight, Pu 'er tea helps digestion and so on, so friends should choose tea according to their physical needs or personal preferences, so as to achieve good physical and mental health.

Second, choose good tea.

Tea quality is good or bad. Generally speaking, high-quality tea has many benefits for tea drinkers. Inferior tea leaves are bitter and astringent, with poor taste.

Third, you can drink tea.

In addition to good tea sets and scientific brewing, don't drink spoiled tea, don't drink tea on an empty stomach, don't drink overnight tea, and try not to drink strong tea before going to bed. Generally speaking, it is better to drink new tea, but you can also drink some old tea, such as old black tea and Pu 'er tea, which can relieve gastrointestinal discomfort.

Fourth, look at the time.

It is suitable for drinking black tea in the morning, because black tea belongs to fermented tea, which has a gentle personality and will not stimulate the body; Suitable for drinking green tea during the day, which helps to refresh; It is appropriate to drink oolong tea or black tea after dinner, both of which are beneficial to digestion, but will not affect the rest at night.

Fifth, look at physical fitness.

If the body heat is more suitable for drinking green tea, drink scented tea when you are in a bad mood, with thick tongue coating, soothing the liver and regulating qi, bloating and indigestion. It is suitable for drinking oolong tea or Tieguanyin semi-fermented tea, which is helpful for eliminating dampness.

Tip: Wash tea sets frequently.

Some people often drink tea, and there is often a layer of "tea dirt" in the cup. Some people think that tea sets brewed with tea dirt are more delicious. In fact, tea dirt is extremely harmful to human health. Tea scale is produced by tea polyphenols in tea and metal oxidation of tea in the air. Cadmium, lead, arsenic, mercury and nitrite harmful to human health will adhere to the smooth surface of the teacup. After entering human body, tea dirt will combine with protein and fat in food to form insoluble precipitate, which will hinder the absorption of nutrients. In addition, it is easy to breed bacteria on tea scale.

Tea mainly contains alkaloids, tea polyphenols, sugars, organic acids, aromatic substances, vitamins, inorganic salts and other nutrients, among which tea polyphenols are the most important, which can account for 20%-35% of the dry weight of high-content tea. Tea polyphenols are polyphenols with catechins as the main body, and they are antioxidants that can delay aging and enhance the immune effect of the body. They can not only prevent arteriosclerosis and cardiovascular diseases, but also play an appropriate role in cancer prevention.

Tea is also a master of lipid-lowering, which helps to reduce uric acid and prevent gout. Catechins in tea can inhibit the production of uric acid, thus increasing the concentration of uric acid in blood, thus preventing gout. Although tea has such good advantages, the drinking method is actually very important. Most people actually don't drink tea, at least drinking tea is unhealthy.

Although drinking tea is good, the method is very particular. Pay attention to the method of drinking tea, which can better play the health care role of tea.

It is not advisable to drink tea on an empty stomach: drinking tea on an empty stomach is like "inviting wolves into the room", which is prone to some reactions such as palpitation and frequent urination, and will also affect the body's absorption of some nutrients.

Drinking tea before and after meals is not recommended;

Drinking tea before meals will dilute digestive juice and reduce appetite, while drinking tea after meals will prolong food digestion time and increase gastrointestinal burden; Tea also contains a lot of tannic acid. If you drink tea immediately after a meal, protein, iron and tannic acid in food will easily condense, which will reduce the absorption of protein and iron, affect various physiological functions of organs and easily cause iron deficiency anemia.

Drink tea in moderation:

It is recommended not to drink a lot of strong tea, otherwise the heart rate will increase and blood pressure will rise, causing insomnia. Insomnia and ulcer are not suitable for drinking more tea. Generally, healthy adults have the habit of drinking tea. The daily consumption of tea should be around 15g, and it is appropriate to brew it in 3-4 times.

It varies from person to person, so don't drink tea indiscriminately.

If you belong to cold constitution, you can drink black tea; Those with warm constitution should drink green tea; For people with obesity and hyperlipidemia, oolong tea is recommended.

Tea beverage is not "tea", so choose carefully:

Now many businesses are well versed in the psychology of consumers. There are many so-called "healthy drinks" tea drinks in the market, which are especially popular with young consumers. However, they are by no means equal to tea and can never replace natural tea. Imagine how sweet natural tea can be. How much tea is there in the tea drink? Can you get the health care function of tea in tea beverage? When you make tea drinks, it is inevitable to add various preservatives, pigments and sweeteners, which will only make you farther away from health. So I suggest you be healthier in taste and health.

In a word, tea is a good thing, but you must drink it reliably and healthily. Drinking tea indiscriminately will also increase the burden on the body. Did you do it?

Tea can be drunk every day, but the efficacy and function of tea are different. I suggest drinking tea according to its characteristics and functions. You can drink it according to: spring tea, summer green tea, autumn green tea and winter black tea. Only by choosing and drinking tea reasonably can tea play its greatest role.

Drinking scented tea in spring: In spring, people generally feel sleepy and weak. Drinking scented tea can alleviate the adverse effects of spring sleep. Scented tea tastes sweet and cool, but its fragrance is pungent, which is beneficial to dispel the cold evil accumulated in the human body in winter, promote the growth of yang in the body, make people feel refreshed and make the "spring sleep" disappear on its own.

Drinking green tea in summer: People in summer consume a lot of energy and sweat easily. Green tea belongs to unfermented tea and is cold in nature. "Cold can clear away heat", which can remove fire, promote fluid production to quench thirst, promote digestion and eliminate phlegm, and accelerate the healing of oral cavity and mild gastric ulcer.

Drinking green tea in autumn: the climate in autumn is dry, and green tea, also known as oolong tea, belongs to semi-fermented tea, which is between green tea and black tea. It has both the fragrance and natural floral fragrance of green tea and the mellow fragrance of black tea. Not cold or hot, mild. It has the effects of moistening skin, moistening throat, promoting fluid production, eliminating accumulated heat in the body, and adapting the body to changes in natural environment.

Drinking black tea in winter: in winter, the temperature is low, the physiological function of the human body declines, the yang is getting weaker, and the physiological activities of the human body are in a state of inhibition. Black tea is sweet and warm, which can nourish human yang; Black tea is rich in protein and sugar, which can warm the abdomen by heating, enhance the cold resistance of human body, and help digestion and greasy.

In addition, after choosing the right tea, let it play its greatest role. Different teas have different methods of preservation, brewing and drinking. Knowing more is good for your health. I hope everyone is healthy!
