Green tea: composition, properties for the human body, benefits and harms

Green tea is one of the most popular products of our time. Absolutely everyone drinks it: both adults and children.

He entered our lives so much that at the moment many people cannot even imagine their morning or evening without a cup of fragrant green tea. He is a regular at any party or tea party. It is especially highly valued in England, China and the countries of the Far East.

This product contains a huge amount of various antioxidants that protect against the negative effects of free radicals. It is drunk with a cold, often adding honey or milk.

A bit of history

In China and the countries of the Far East, there is an opinion that tea will replace any wine with its invigorating properties. And in China, one very ancient legend is widespread. It is still being told to residents and tourists about the origin and discovery of tea. Four thousand years ago, a shepherd watching his sheep saw that some of them were chewing tea shoots. After the meal, the animals suddenly began to be distinguished by unexpected activity and extreme mobility. The man immediately understood everything, picked a few leaves. A little later, he threw them into boiled water, which served to further use this decoction among people.And to this day, people drink this drink full of magical properties.

For a long time, leaves that have not been processed have been used. This lasted until the 1st century BC. Later, people still began to fry or dry them.

Over time, in the process of historical development, mankind began to use many tea plantations. Further, drinking such tea in the circle of important people or at any ceremony has become something traditional and natural. All these changes took place during the reign of the Tang dynasty, namely: in the 7th-10th centuries. There were also some fun. For example, there were times when famous tea masters arranged some kind of competition among themselves. Their task was to prepare the best drink.

In the 10th-13th centuries, dishes already traditional for today appeared, designed for making a drink. Japan did not lag behind China, so branded utensils and even tea ceremonies also appeared in the Land of the Rising Sun.

Korea and India will also be no exception. This product reached Europe with some delay, only in 1583. It is worth noting that Portugal and Holland are among the first countries to learn about this wonderful decoction. England is a country that everyone, without exception, associates with tea. However, it began to be used only in 1665. Having annexed Ceylon, the British bred their own varieties there, but they preferred black varieties more.

The very first Russian person who tried green tea was Mikhail Fedorovich - the Russian Tsar. Then tea was already tasted by his boyars. All this happened in 1617, when the envoys of the Asian rulers delivered a couple of bags to Moscow.However, this drink did not reach the peasants, it was drunk exclusively by people who were distinguished by their wealth and power. But in the nineteenth century, the peasants also experienced all the positive qualities of this decoction. In Russia, Tatars, Kalmyks, Buryats have been drinking tea for a long time, they especially like a drink with the addition of milk.

Citizens of Russia did not like teas with the addition of milk or other products for a very long time. But, when supplies of the same green tea, which was in short supply, began, they radically changed their minds.

Useful properties, taste, aroma of tea are especially good for the evening after a hard day's work, to relieve fatigue and cheer up.

Description

If we leave the question of the origin of green tea, then another one appears, namely, what it is, what its chemical composition and properties are. It's funny: many people mistakenly believe that green and black tea differ from each other in their plants, which are used as ingredients. But for both, the same leaves are used. Usually it is a tea bush or camellia. However, the approach to these leaves is different.

To make green tea, it is necessary to oxidize its leaves, and then carefully steam it. With black, everything is a little different. It is also worth knowing that green tea is subjected to extremely low fermentation.

We present green tea as the final product of processing, namely: boiling and steaming. If you ask a plantation worker or watch a documentary, you can find out that before the product reaches the consumer, it looks like ordinary raw leaves. They are dug up, placed in a basket, and then sent to processing sites. Using very hot steam, these leaves are fermented.This procedure continues for no more than three days. As for the color, it is worth knowing that the color of the untreated leaves is green. He, in turn, already has different shades, both light and dark. Having brewed a drink, you can see a light-colored liquid, mostly green. Its taste is very tart, and the smell is simply amazing.

Poor quality tea or incorrect brewing can be identified by a sharp unpleasant taste. Most often, this taste is extremely strong. Proven tea of ​​the highest quality is much more expensive.

Asians are very fond of the so-called brick tea, which consists of branches and leaves. Usually they contain at least 70% of the leaves, this makes them stand out with amazing flavors and a long shelf life.

Of no small importance is the chemical composition of the drink:

  • vitamin C;
  • vitamin K;
  • fluorine;
  • copper;
  • magnesium;
  • iodine;
  • vitamin P;
  • polyphenols;
  • caffeine;
  • vitamin B1;
  • vitamin B2;
  • vitamin B15;
  • vitamin RR.

High immunity appears due to vitamin C. It protects the body from various diseases. It is worth noting vitamin B2, which contributes to the elasticity of the skin. But all scientists and highly qualified doctors secrete vitamin P, which strengthens blood vessels and the nervous system.

The combination of all these vitamins and antioxidants has a preventive effect even with a few tea cups. But for the desired effect, you need to drink it regularly several times a day.

Kinds

It is not uncommon to find "related compositions" on the market. Usually they are bought as a souvenir from an unusual exotic place. Many charlatans and scammers unceremoniously take quite a lot of money from their consumers, while selling not true fragrant green tea, but a real cheap fake. In order not to fall for the tricks of swindlers, it is necessary to study all the properties and qualities that high-grade teas have.

You need to know that the best tea is large-leaf. Packaged will not be what many consumers would like.

If we talk about this variety, then it is worth remembering that it is one of the ten best collectible drinks. It is very famous, it is collected in the Anhui mountains.

It is noteworthy that the decoction after preparation remains as fresh as at the time of collection. At the very end, the leaves are sent to the oven degrees - for drying. The color of the drink is clearly transparent, and the taste is unique. The temperature of the water in the cup should be 80 degrees.

"Bai Mayo Howe"

Of course, the entire range does not end there. In fact, there are many more tea types and varieties, but it is simply impossible to list them all - there are special books for this.

Separately, it is worth mentioning tea bags, although it is difficult to call it tea. The fact is that often not tea leaves are added to the bags, but dust after processing real elite large-leaf tea. Therefore, when buying bags, you should be more careful and prudent.

The influence of the drink

You can talk about the beneficial qualities of tea for a very long time. In one sentence, green tea is an incredibly strong drink capable of preventing many diseases. About its composition is written above, and having carefully studied it, you can at least roughly understand why it is so in demand in the modern world.

With its use, the vessels become more elastic, and the pressure normalizes rather quickly.

One of the main reasons for drinking tea is the fact that the risk of stroke or heart attack is almost halved.

It also helps to remove unnecessary toxins that interfere with the full functioning of the whole organism. In case of poisoning or constipation, it will also be far from superfluous. Many drink it during colic.Another fact tells us that it is very good for weight loss. A large number of girls and women drink this tea in liters, hoping for the cherished deliverance from extra pounds. To some extent, this is not in vain. Green tea speeds up metabolic processes, which allows fat to be burned. When it is used, the ability to purify the blood increases, which is important for the state of the immune and nervous systems. A person who drinks this product usually has excellent health, since doses of vitamin C are constantly supplied to his body. Due to this, viruses and diseases bypass the body.

Diuretic or not?

Many people drink it for swelling. There is an opinion that the elements and vitamins contained in green tea speed up the metabolism and the breakdown of salts. Therefore, it can be considered a diuretic. Moreover, in folk medicine it is used very, very widely. Recently, scientists discovered caffeine in its leaves - with its help, filtration in the kidneys occurs many times faster and better.

Thus, if this tea is consumed daily, then the work of the kidneys and many other organs improves markedly.

Invigorates or calms?

On this issue, opinions are divided into two opposing ones: some believe that it has a calming effect, while others are sure that it gives vigor and activity. It all depends on how the tea was prepared. Many doctors agree that 2 minutes after brewing with water at a temperature of 70-80 degrees, tea is considered exciting. If you add water to an already used brew and steep for a few minutes, you get a soothing tea. And after 20-30 minutes, the leaves will give up all the tonic substances, so the drink will have this property for several more hours.

Is there any harm from it?

Like any other product, green tea can also be harmful, and to some extent even dangerous. It has some contraindications.

  • There are some medications based on this drink. In such preparations, the concentration of catechins is too high, which creates a surplus of the norm.
  • You can not drink this tea on an empty stomach, as this directly affects the mucous membranes.
  • You can not drink it after taking alcoholic cocktails, since when combined with raw materials, they create very harmful compounds that can disrupt the liver.

When foam appears on tea, it is forbidden to use it: it indicates the toxicity of tea. This usually happens about 11 hours after brewing.

Can children drink?

    Of course you can. For children at their young age, green tea will be most welcome, as its unique properties will affect the children's brain very favorably. The elements that it contains affect the proper growth of teeth, hair, bones, and so on.

    But before giving this drink to a child, it is necessary to consult with his pediatrician. Not all children, due to their age and health factors, should drink this product. It affects everyone in different ways, invigorates some, calms others and plunges them into a deep sleep. It all depends on the child and his parents.

    Doctors' opinion

    Among all doctors, green tea has only good reviews and characteristics. In medical programs, it is recommended to drink it due to the fact that it has a beneficial effect on pressure, the nervous, reproductive and urinary systems. Of course, you can list for a long time, but, nevertheless, all doctors are similar in one thing - this product can and should be drunk. But some positive qualities do not exist in any decoction, and this one is no exception. All pros and cons are described above.

    Manufacturers Overview

    The production of green tea is a profitable and very stable business. Due to its huge popularity, a huge number of different companies took up its production. Let's list some of the most popular.

    • Tess. It's strange why it's so popular, since its flavor just can't match that of true loose leaf tea. This is due to the fact that such products placed in bags are not real tea. Rather, it is a product left after processing, or, to put it more simply, dust.
    • It is impossible to ignore the Thai manufacturer - Siam Tea Factory. Most of the people who tried this drink assured that there is nothing tastier in the world than this. This is especially true for teas from this series, but with the addition of milk. It is a unique and special blend of local herbs and green teas that will be remembered for years to come.
    • Lipton. Another very famous company that supplies the world with tea bags. The taste is not bad, but if you remember what is in these bags during tea drinking, then the desire to finish drinking will instantly disappear.
    • green field. Pretty good branded product. The manufacturer can offer its customers both sheet and packaged products. However, they shouldn't get too carried away. It is best to pay attention to goods of higher quality and, accordingly, prices.

    Helpful Hints

    For proper brewing, only high-quality, high-grade tea leaves are needed, preferably large-leaf varieties. These sheets contain much more of the necessary properties, and when brewed, the taste and aroma are noticeably better and more pleasant. To brew it, take purified water, preferably bottled or filtered water. In situations where such liquids are not at hand, the settled one is used. It is not worth pouring from the tap, as this water may contain bleach or other substances that can spoil the taste and health. But also in no case should you boil water a second or third time. For the best brewing, only fresh water is needed.

    So, water is poured into the kettle, then they put it to warm up - on a stove or fire. Here it is very important to remove it in time. The Chinese of the old school argue that for the necessary drink it is necessary to use "living" water. By "alive" they mean water that has not been in a state of boiling for too long. But nevertheless, it should be hot anyway, otherwise no welding will work.

    After reading this manual, many are lost and do not know what to do. Everything is simple. It is enough just to follow the heated water.At the first bubbles of boiling, the water must be immediately turned off. Such a liquid is equal to 93-94 degrees.

    Natives of China and many experts advise using teapots and other utensils that consist directly of porcelain. It perfectly retains warmth in itself, and also allows the drink to collect all the necessary qualities that the aforementioned tea is so famous for. Next, the kettle is thoroughly rinsed with boiling water - this helps to heat it. Then tea leaves are added there. At this stage, you need to be extremely careful, since the further strength of the tea depends on the amount of tea leaves added to the dishes. Then the obtained is poured with "living" water and covered with a lid. If the actions are carried out in the cold season, then you can put a preheated towel on top - this allows the tea to keep it warm and not cool down.

    The brewing process lasts 2-6 minutes. Then the already obtained drink is poured into pre-prepared cups. But in the East there is one ritual, without which the pouring should in no case be started. A small amount of drink is poured into a cup and then returned back to the teapot. The procedure is repeated four times, after which you must wait at least another minute. This is only necessary so that the liquid boils more thoroughly and becomes homogeneous. This ritual is called "marriage", and it came from Central Asia. If in Russian, then the very tea leaves and water are married to each other. After that, the tea is the best of the best.

    There are also rules for drinking this drink. Real gourmets claim that such additions as sucrose, honey, milk and others spoil the drink and do not allow you to feel its true taste. But everyone has their own preferences.

    And this is not the only rule. Different peoples of the world have others.

    • Under no circumstances should it be taken on an empty stomach. If this is done, then constant processes will begin that will lead to the fact that the stomach, which has nothing inside, will literally digest the emptiness. And besides, this tea makes the acidity of the stomach noticeably higher. o after a good meal, drinking it is very pleasant and healthy - it facilitates the process of digestion.
    • Do not drink tea without enjoying its aroma. The vapors it releases provide many benefits to the human skin, and not just the skin - the respiratory system can also benefit from it.
    • Girls and women who drink this drug for weight loss should remember that this should be done immediately after eating. Such a process speeds up the metabolism and, in addition, there are no calories at all.
    • The desired result can be achieved only with regular drinking of the drink.
    • Many drink it in the morning, as the vigor that can be obtained from it is tantamount to vigor from coffee drinks.
    • Tea prepared earlier, for example, a few hours ago, is strictly forbidden to heat. Such an act is considered "blasphemy". It must be poured and drunk cold, adding, for example, a slice of lemon or other ingredients.
    • Women who have recently given birth are advised to add milk to the drink - this contributes to the favorable feeding of the newborn.
    • In no case do they drink it with alcohol, it has a strong effect on the kidneys, and not from the best side.
    • They also do not drink it together with drugs - this reduces the treatment process, makes the drugs not so effective.

    It is important to remember that to buy a product, you need to contact only specialized stores - there you can get not only a quality product, but also a useful free consultation about each type separately.

    Entering the store, you must immediately pay attention to the appearance of the goods offered, namely: the color of the leaves, which should be light green in color without turbidity and various shortcomings. In no case should you take stale tea - it has a harmful effect on the body and all health in general. Its “age” is determined by slag and various debris in it. If it is more than 20%, then it must be immediately postponed, forgetting about it forever. Large-leaf species are distinguished by their quality and taste. Here it is necessary to choose those sheets that are distinguished by their integrity and the absence of cuttings.

    Another important factor is the moisture content of the product. To determine it, take a few leaves and rub them with two fingers. Overdried tea breaks easily and quickly, but if it has acquired the appearance of dust, then it is quite old - its service life has long passed.

    If the place where tea is kept has too high humidity, then it will quickly become a breeding ground for mold, fungus and various bacteria and, accordingly, it cannot be purchased. If a product such as green tea is too wet, then it is sharply pressed during crushing. You can store this product for no more than one and a half years. But it is also important to know that it is necessary to purchase this raw material by weight, and before that it must be smelled. Poor quality gives out the aroma of hay and fruit. Tea in bags, as mentioned above, should not be consumed and purchased in any case - this is not tea, but more often - its remnants after processing.

    There is a universal way to find out how high the quality of the product is, namely: it is poured with heated water, and then they look at the result. In the best case, it will be covered with foam and become quite transparent.

    Separate conversation about the price. Any adequate person should understand that this high quality raw material will not have a low price. Any cost depends on the quality and grade. Prices range from 200 to 1500 dollars or from 300 to 1000 rubles. And here we are talking about 50 grams.

    The choice of tea and its preparation should also be approached very responsibly and strictly. In principle, this is not as difficult to do as it seems, the main thing is to inspect its appearance and check for moisture levels. Each person needs an individual variety, so when buying, you should rely only on personal preferences and tastes.

    As for brewing, there is an individual approach for each product. Before use, you must carefully study the instructions, and then perform the necessary actions directly on it.
