Green tea: composition, properties for the human body, benefit and harm
Green tea is one of the most popular products of our time. Absolutely everyone drinks it: both adults and children.
He came into our lives so much that at the moment many people cannot even imagine their morning or evening without a cup of flavored green tea. He is a regular at any party or tea party. It is especially highly regarded 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. They drink it with colds, 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, a very old legend is common. She and now tell residents and tourists about the origin and the discovery of tea. Four thousand years ago, a shepherd who watched over his sheep, saw some of them chewing on the shoots of a tea bush. After the meal, the animals suddenly became different unexpected activity and extreme mobility. The man immediately understood everything, picked some leaves. A little later, he threw them into boiled water, which was the further use of this broth among the people. To this day, people drink this drink, full of magical properties.
For a long time used leaves that have not been processed. It lasted until the I century BC. Later, people still began to roast or dry them.
Over time, in the process of historical development, mankind began to use many tea plantations. Further, drinking such tea in a circle of important people or at any ceremony became something traditional and natural. All these changes took place during the rule of the Tang dynasty, namely in the VII-X centuries. There were also some fun. For example, there were times when famous tea masters arranged certain competitions among themselves. Their task was to prepare the best drink.
In the X-XIII centuries, the traditional dishes of today for the preparation of the drink appeared. Japan did not lag behind China, so branded utensils and even tea ceremonies also appeared in the Land of the Rising Sun.
No exception will be also Korea, and India. This product reached Europe with some delay, only in 1583. It is worth noting that Portugal and the Netherlands are among the first countries to learn about this wonderful broth. England is a country that everyone, without exception, associates with tea. However, it was used only in 1665. Having annexed Ceylon, the British brought their own varieties there, but it was the black varieties that preferred more.
The very first Russian person to try green tea was Mikhail Fedorovich - the Russian Tsar. Then tea was tried 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, only people who were distinguished by their wealth and power drank it. But in the nineteenth century, the peasants also experienced all the positive qualities of this broth. In Russia, Tatars, Kalmyks, Buryats have been using tea for a long time, especially they like a drink with the addition of milk.
For a very long time, citizens of Russia did not like teas with the addition of milk or other products. But when the supply of that very green tea, which was in short supply, began, they radically changed their opinion.
Useful properties, taste, aroma of tea are especially good for the evening after a hard day at work, in order to relieve fatigue and lift the mood.
Description
If you leave the question about the origin of green tea, then another one appears, namely what it is, what its chemical composition and properties are. 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 thoroughly steamed. Black is a bit different. It is also worth knowing that green tea is subjected to extremely low fermentation.
We present green tea as a final product of processing, namely: boiling and steaming. If you ask the plantation worker or watch a documentary, you can find out that before the product reaches the consumer, he has the appearance of ordinary raw leaves. They are ripped up, put in a basket, and then sent to the processing sites. Using very hot steam, these leaves ferment. This procedure lasts no more than three days. As for color, it is worth knowing that the color of the raw leaves is green. He, in turn, has already different shades, both light and dark. Brewing a drink, you can see the liquid light color, mostly - green. Its taste is very tart, and the smell is just amazing.
Low quality tea or improper brewing can be identified by a sharp unpleasant taste. Most often, this taste is extremely strong. Proven top quality tea is much more expensive.
Asians are very fond of the so-called brick tea, which consists of twigs and leaves. Usually they contain at least 70% of the leaves, it highlights their amazing tastes and long shelf life.
Equally important 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 PP.
High immunity appears due to vitamin C. It protects the body from various diseases. It is worth noting vitamin B2, which promotes skin elasticity. 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 prophylactic effect even with the help of several tea cups. But for the desired effect, you should drink it regularly several times a day.

Manufacturers Review
Green tea production is profitable and very stable. Due to its immense popularity, a huge number of different companies took over its production. Here are some of the most popular.
- Tess. It is strange why it is so popular, since its taste simply cannot match the taste of true leaf tea. This is due to the fact that such products, placed in bags, are not real tea. It is rather a product remaining after processing, or, more simply, dust.
- It is impossible to ignore the Thai manufacturer - Siam Tea Factory. Most people who tried this drink assured that there is nothing tastier than this in the world. This is especially true of tea from this series, but with the addition of milk. This is a unique special blend of local herbs and green tea, its taste will be remembered for many years.
- Lipton. Another very well-known company that supplies teabags to the world. The taste is not bad, but if during tea-drinking we remember what is in these bags, then the desire to drink up will instantly disappear.
- GreenField. Pretty good brand products. The manufacturer can offer its customers as well as sheet and packaged products. However, to get involved in them is not particularly worth it. It is best to pay attention to goods of higher quality and, accordingly, prices.
Useful tips
For proper brewing, only high-quality tea leaves of high grade are required, preferably varieties of large leaves. In these sheets, the desired properties are much more, and when brewing, the taste and aroma are noticeably better and more pleasant. To brew it, take purified water, preferably water from a bottle or filtered. In situations where there is no such liquid at hand - use the settled. It is not worth pouring out from under the tap, as this water may contain bleach or other substances that can spoil the taste and health. But also in no case can not boil water a second or third time. For the best brewing need only fresh water.
So, water is poured into the kettle, then they put it to warm - on the stove or fire. It is very important to remove it in time. The Chinese of the old school claim that it is necessary to use "live" water for the necessary drink. By “living” they mean that water that has not been in a state of boiling for too long. But nevertheless, it should be hot anyway, otherwise there will be no welding.
After reading this manual, many are lost and do not know what to do. It's simple. It is enough to follow the heated water. At the first bubbles of the boiling water must be urgently turned off. This fluid is 93-94 degrees.
People from China and many experts advise the use of kettles and other dishes, which consist directly of porcelain. It perfectly keeps in itself warmth, and also allows the drink to collect in itself all those necessary qualities with which the above-mentioned tea is so famous. Next, the kettle rinse thoroughly with boiling water - it helps to heat it. Then tea leaves are added there. At this stage, you need to be extremely careful, because the amount of tea depends on the amount of tea leaves added to the dishes. Then, the resulting is filled with "living" water and cover with a lid. If actions are carried out in a cold time, then a pre-heated towel can be put on top - this allows the tea to keep it warm and not to cool.
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 spill in no case can not begin. A small amount of drink is poured into a cup, and then returned to the kettle. The procedure is repeated four times, after which you have to wait at least another minute. This is necessary only to ensure that the liquid boils more thoroughly and becomes homogeneous. This ritual has the name "marriage", and it came from Central Asia. If in Russian - then the very tea leaves and water marry among themselves. After that, the tea turns out the best of the best.
There are also rules for drinking this drink. Real gourmets say that such additions as sucrose, honey, milk and others - spoil the drink and do not allow to feel its true taste. But everyone has their own preferences.
And this is not the only rule. Different nations of the world have others.
- In no case do not take it on an empty stomach. If this is done, then invariable processes will go that will lead to the fact that the stomach, having nothing inside, will literally digest the emptiness. And besides, this tea makes the acidity of the stomach much higher. About after a good meal, drinking it is very pleasant and helpful - it facilitates the process of digesting food.
- Do not drink tea without enjoying its flavor. The vapors that he produces have many useful properties for human skin, and not only for the skin - the respiratory organs can also benefit from it.
- Girls and women who drink this drug in order to lose weight should be aware that this should be done immediately after a meal. This process speeds up the metabolism and in addition, the calories are completely absent.
- The desired result can be achieved only with regular drinking.
- Many people drink it in the morning, since the vigor that can be obtained from it is equivalent to the vigor from coffee drinks.
- Tea prepared earlier, for example, a few hours ago, warming is strictly prohibited. Such an action is considered "blasphemy." It is necessary to pour, and drink cold, adding, for example, a slice of lemon or other ingredients.
- Newly born women are encouraged 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 don’t drink it with drugs - it reduces the treatment process, makes the drugs not so effective.
It is important to remember that in order to purchase goods, you need to apply only to specialty stores - there you can get not only a quality product, but also a useful free consultation separately about each type.
Going into the store, you must immediately pay attention to the appearance of the goods offered, namely: the color of the leaves, which should be a light green color without haze and various shortcomings. In no case it is impossible to take a seized tea - it adversely affects the body and all of health in general. Its “age” is determined by slags and various debris in it. If it is more than 20%, then it must be immediately postponed, forgetting about it forever. Large-leaved species differ in their quality and taste. Here it is necessary to choose those leaflets that are distinguished by their integrity and lack 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. The 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 held has too high humidity, then it will quickly become a breeding ground for mold, fungus and various bacteria and, accordingly, cannot be acquired. If a product such as green tea is too moist, then it is dramatically compressed during a crush. Store this product can be no more than one and a half years. But it is also important to know that it is necessary to acquire this raw material by weight, and before that it needs to be smelled. Poor quality gives out the flavor of hay and fruit. Tea in bags, as mentioned above, can not be consumed and purchased in any case - it is not tea, but more often - its residues after processing.
There is a universal way to find out how high the quality of a product is, namely: it is watered with heated water, and then they look at the result obtained. In the best case, it will foam and become quite transparent.
A separate conversation about the price. Any adequate person should understand that this high quality raw material will not have a low price. Every cost depends on the quality and variety. 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 as it seems, the main thing is to examine its appearance and check for moisture levels. An individual variety is required for each person, so when buying, you should rely only on personal preferences and tastes.
As for welding, 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.
