Everything you need to know about green tea. All about green tea: secrets, facts, history and ranking of the best varieties

Green tea- the drink is not unique. It is made from tea tree leaves that have not been fermented. Known rich chemical composition green tea. What a person eats and drinks affects his health. Drinks that are sold in stores contain chemicals that are not very good for the body.

What a drink for a long time there is no doubt - it's green tea. However, it is worth knowing all its features, because green tea can bring benefits and harm to health to the same extent.

Compound

Due to the fact that the processing of fresh products mainly consists in evaporating moisture from the tea leaf, the color and composition of the finished tea leaves are as close as possible to the natural original product. Only concentration useful substances becomes many times larger.

The chemical composition includes such an abundance of elements that green tea is considered one of the most valuable products for the human body. It contains vitamins, microelements, and macronutrients.

Tea composition:

Vitamins - for example, vitamin P, which contributes to the health and elasticity of blood vessels and supports the cardiovascular system as a whole; vitamin C, which is more in green tea than in lemons and oranges; vitamin K, which ensures normal blood clotting; vitamin B, which has a beneficial effect on nervous system; vitamins A, PP, D and E.
Minerals and trace elements - for example, zinc, necessary for the growth and strengthening of hair, teeth and nails; as well as iodine, which supports the endocrine system; fluorine, which strengthens the gums and teeth; potassium is a friend of the heart muscle; copper, promoting women's health, and manganese. The minerals contained in the leaves help the proper functioning of internal organs, strengthen the immune system, maintain the balance of all body systems and normalize metabolism, which, among other things, contributes to weight loss.
Caffeine - well, everyone knows caffeine, its invigorating and tonic properties are familiar to coffee lovers, but with green tea It is not that simple. The fact is that it contains “another caffeine” - theine, the effect of which is much softer, and at the same time longer. In addition, it is excreted from the body completely, without causing side effects. When I, an experienced coffee addict, suddenly began to jump pressure, my doctor recommended replacing morning coffee with green tea, and the positive experience inspired me so much that I completely switched to it. Surprisingly, the pressure returned to normal.
Antioxidants - flavonoids (catechins), which not only slow down the aging process, but even protect against cancer. There is an opinion that green tea, rich in catechins like no other, slows down and even stops the growth of tumors. Catechins also regulate blood sugar, which makes this drink incredibly beneficial for diabetics.

Green tea contains four main catechin components. Only one of these components is 100 times the antioxidant properties of vitamin C. Studies have shown that a cup of green tea contains up to 40 mg of polyphenols, which is many times higher than the antioxidant effect of the same apples, spinach or broccoli.

Harm of green tea

The composition of green tea includes substances that have both positive and negative effects on the human body. In addition, green tea contains theophylline and theobromine, which have a stimulating effect on the human nervous system. That is why the infusion of tea leaves is not recommended for people with increased excitability and insomnia.

Remember that the recommended temperature of the brewing water is around 80-90 degrees. Without a thermometer at hand, determining the right temperature is quite simple. It is necessary to open the lid of the kettle and when the steam begins to rise, bring your hand to it. The steam must not burn the hand. This is the optimum temperature. Learn once and for all - boiling water destroys most of the beneficial substances in tea, making this drink useless!

A strong drink is definitely harmful in such situations:

During pregnancy. It interferes with the natural breakdown of folic acid, which is so vital to the developing brain of an unborn baby. All this is due to the content in it of a large dose of a chemical drug with the unpronounceable name "gallatepigallocatechin". Again, we mention caffeine, which is contraindicated for pregnant women. Whether black tea prevents the breakdown of folic acid has not been proven for certain, but it does contain caffeine. Just a few cups of any tea per day can cause the birth of a child with low weight, stimulate premature labor with possible fetal death.
With an unstable nervous system and with diseases of the cardiovascular tract. Of course, theine is bad for them. But tea is rich not only in theine, it contains substances that actively influence these systems, which causes its harmful effects, for example, due to theobromine.
With a stomach ulcer. Rather, tea is contraindicated than really harmful. Strong tea, and green tea in particular, increases the acidity of gastric juice, and this, in turn, interferes with the natural process of wound healing. As a result, the patient's condition may worsen significantly.
At a temperature. Tea contains theophylline, which can raise a person's temperature. Therefore, a patient with a temperature, drinking green tea, will worsen his condition even more.
With an unhealthy liver. This is where green tea comes into play. Some of the compounds found in tea are extremely taxing on the liver, especially if the drink is drunk in large quantities. But in black tea, these compounds are very few.
For the skeleton and bones. The analyzes put by scientists on animals showed unexpected results. It turns out that tea has a negative effect on the skeleton and, in particular, on the density of bone tissue. In fairness, we note that such studies have not been done on humans.
Washing out beneficial trace elements. Tea removes metals from the body. Again because of theine.
For teeth. Although the opposite effect was mentioned here, there is evidence that tea has a detrimental effect on tooth enamel. What to believe? You can’t answer for sure, but it’s hardly worth rinsing your teeth with tea when brushing.
Urea formation. Any tea is rich in purines, which in the process of assimilation synthesize urea. It is known to be poisonous, and is removed from the body with difficulty. Its salts synthesize crystals that develop gout. In addition, green tea disrupts the condition of people suffering from arthritis and rheumatism.

What is harmful green tea bags:

The composition of the vast majority of brands of packaged teas includes the so-called tea debris (damaged leaves, petioles, sticks), which is rejected in the production of high-quality loose leaf teas. The taste and benefits of such tea dust are minimal.
Many brands of tea in bags, in addition to the tea leaf itself, contain various plant components (tree leaves, grass) of dubious quality or origin.
Often, expired tea leaves are used for the production of tea bags. The composition of the paper in which tea is packaged includes thermoplastic fiber (for shaping). This substance, in contact with hot water, releases various harmful substances.

Extremely hot drink should not be taken in large doses. Therefore, if you constantly consume excessively heated tea, burns of the internal organs inevitably occur. They are deformed, painfully shrink, cracks form on the tissues. These types of burns certainly increase the risk of cancer. It should be noted here that this is not a harm to tea as such.

Benefits of green tea

The beneficial properties of green tea have long been used in Asia - China, Japan, Central Asian peoples use this "health cocktail" daily: chilled in the heat, hot - in the cold season. Look at Japanese women - their wonderful skin, youthfulness and harmony have long served as a model for all women.

Of course, a seafood-rich diet also plays an important role in maintaining youth and health, but the "drink of life" - green tea - is one of the most important components of this diet. Do you think that in vain movie stars and glamorous divas in their expensive spas have long ago made it a fashion to indulge in a cup of green tea, which is excellent for cleansing and rejuvenating the body?

The product has a huge number of useful properties, but the most important of them are:

Decreased growth of cancerous tumors. Ability to stop and retard growth different kind tumors and fight the activity of cancer cells (however, according to some studies, green tea is ineffective against breast tumors).
The ability to remove free radicals from the body and protect against the effects of increased radiation.
Prevention of diseases of the cardiovascular system up to heart attacks and strokes, lowering blood pressure.
Breakdown of fats, removal of harmful cholesterol from the body, normalization of metabolism and weight control.
Fight against diseases of the oral cavity, eliminate periodontal disease and bad breath, prevent tooth decay.
Normalization and maintenance of healthy intestinal microflora.
Removal from the body of toxins, salts, including compounds of radioactive metals.
Maintaining vigor and daily activity, combating reduced vitality, drowsiness, headache.
Improvement of brain (mental) activity, reaction.
Removal of anxiety, depression, stress, normalization of sleep (with proper use).
Reducing the harmful effects of tobacco on the body.
Fight against urolithiasis and cholelithiasis. Restoration of water balance in the body.
Slow down the aging process, increase general tone organism.
Improving the work of the endocrine, cardiovascular, immune and digestive systems.
Maintaining visual acuity, good skin and hair condition.

How to prepare green tea

There are many recipes for making this drink, but first of all, you need to understand what kind of effect you want to achieve by using it. If it's a matter of taste preferences, then you can brew it almost anywhere - someone likes the combination of tea with milk or lemon, someone chooses flavored or mixed varieties, some add a drop of honey or sugar to their taste.

use ceramic, porcelain or glassware for brewing;
brew tea with not too hot water - 60-80 degrees will be enough (tea will be brewed even in absolutely cold water). In order to determine whether the water has reached the desired temperature, you need to listen - bubbles in boiling water should make noise like wind in a pine forest;
during brewing, you should not put sweet additives - it is better to add them immediately before use;
various additives to tea will help enhance certain properties of tea - tea with milk will help satisfy hunger; hibiscus will enhance metabolic processes and give the tea a slight diuretic effect.

Green tea will turn out much tastier if you heat the teapot with steam, pour tea at the rate of a teaspoon per glass, pour hot water over it. You can brew tea with milk, or make tea in the usual way and top up with milk to taste. Such a drink will help satisfy hunger and normalize blood pressure.

Green tea raises or lowers blood pressure?

As you know, the terms arterial hypertension and arterial hypertension are considered synonymous. Although, to be precise, “hypertension” means an increase in vascular tone, and “hypertension” means “an increase in pressure in the system.”

An increase in blood pressure up to 140/90 mm Hg. not always associated with an increase in vascular tone. High values can be observed with their normal and even reduced tone due to an increase in cardiac output due to various reasons. Therefore, discussions about the benefits of green teas for lowering or increasing blood pressure continue.

According to one point of view, there is no change in indicators. Caffeine, which is part of the composition, stimulates cardiac activity, which initially increases blood pressure. At the same time, the vasomotor center of the medulla oblongata, which is responsible for the narrowing or expansion of blood vessels, gives the command to reduce the tone, as a result of which the indicators quickly return to normal. Studies have found that a green drink has the property of thinning the blood, making it more fluid. As a result, the load on the heart muscle is significantly reduced, pressure indicators are normalized, and the risk of stroke is reduced.
Other studies, with varying degrees of certainty, confirm the benefits of green tea to reduce the level of "bad" cholesterol, strengthen and increase the elasticity of the walls of blood vessels due to the high content of tannins in it. The best effect is achieved when using high-quality varieties made from the top young leaves.
Green tea varieties are useful for their diuretic effect and therefore can be used in the treatment of cardiovascular or kidney diseases, reducing swelling. The results obtained allow us to recommend that everyone who is healthy drink a green drink to reduce the risk of arterial hypertension, as well as in the initial stage of this disease. Many patients report normalization or a noticeable decrease in performance, improvement. But it is not necessary to talk about the complete cure of the disease in this way.

More years of research is required to draw a more definitive conclusion about the blood pressure lowering benefits of green tea when consumed regularly.

Green tea with milk

Perhaps the most healthy drink for tooth enamel, it is green tea with milk, in bags or brewed from the leaves. Due to the high content of calcium (495 mg), it effectively strengthens tooth enamel and prevents its thinning. In addition, when consumed with milk, tea does not stain teeth (unlike black tea, the pigment of which is not always neutralized even by milk).

Another property that green tea in bags with milk is useful for is that it has an alkaline environment (thanks to milk), which means it can neutralize the acidity of the stomach. Therefore, the benefits of green tea with milk in any form for people suffering from heartburn, gastritis, and high acidity are obvious. When ingested, this drink, due to its alkaline environment, reduces the acidity of gastric juice. As a result, the severity of attacks of gastritis and heartburn decreases. To improve the taste, it can be consumed with honey, jasmine, mint, lemon balm and other additives.

What is the best way to drink green tea?

To maximize the benefits of green tea, choose high-quality large-leaf products. It is desirable that the product contains only one ingredient. If you want to improve taste qualities, then you can do it yourself by adding natural products, not flavors of unknown origin.

Tea is drunk freshly brewed. Within an hour, the concentration of vitamins in it is significantly reduced. Do not heat tea, because harmful compounds are formed in it. High-quality varieties are brewed 2-3 times, while the time for infusion increases by 20 seconds each time.

A hot drink destroys tooth enamel, irritates the stomach, and a cold drink is poorly absorbed and becomes less useful.

Green tea is a very useful product for many people. But is it? The dangers and benefits of tea have been debated for a long time. Let's figure it out.

It is undeniable that tea gives us a pleasant pastime not only because of its taste, aroma, but because of its ability to tone up, give strength and energy, and cheer up. Green tea is also perceived by many as a medicine, because it tends to reduce arterial pressure while being hot and raise it if the drink is cold. Green tea has been proven to lower cholesterol, fight body fat, boost the immune system, and more.

As you know, tea, be it green, black or white, is still tea. The difference is only in its processing and storage. If you go to a specialized store, you can see many varieties, both green and black tea. The taste of tea changes from strong to tender due to the production technology when choosing raw materials - buds, young green upper leaves or fully ripened leaves. The highest quality tea is obtained from the first leaves of the tea bush.

It is believed that the most useful and sought after teas are grown in China and produced in Japan. If we compare green and black teas, or rather the technology of their production, then in the production of green tea, more gentle processing of the leaves is used, therefore green tea has much more benefits than black tea.

Fermentation and further processing of tea

The fermentation of tea determines whether it will be black or green, red or white. Tea fermentation is the degree of oxidation of tea leaves during their drying. It is believed that the less fermented tea is, the more it retains the original herbal taste, the aroma of fresh herbs and useful substances.

The further processing of tea leaves (twisting) determines how long its natural properties will last and how much better it will be brewed. Further drying of tea is necessary to remove the remaining moisture, after which the finished tea product has a dark color, persistent aroma and mild taste. Store such tea only in hermetic opaque packages.

Useful properties of green tea

The composition of green tea includes the following beneficial substances:

caffeine or theine- psychostimulant. Green tea has more caffeine than black tea because green tea is processed more gently. Therefore, when they say that green tea is less invigorating, this is fundamentally not true.
Catechins- antioxidants that destroy free radicals and remove cadmium and lead metals, radioactive compounds and mercury. They are also tannins
Tannins- fight pathogenic microorganisms, have disinfectant, anti-inflammatory and astringent properties.
Tannat is a combination of tannin with theine, which slows down the absorption of caffeine. If we compare the properties of green tea with coffee, then green tea is milder in terms of invigorating effect.
Polyphenols- flavonoids or substances that are responsible for the state of vascular permeability
Vitamins: C, A, K, P, PP and group B, pantothenic acid. Vitamins in green tea after processing are stored much more than in black tea.
trace elements: potassium, copper, iodine

How to brew green tea

The preservation of the beneficial properties of tea depends on how well we know how to brew it correctly.

First way

Use a porcelain teapot to brew green tea.
Rinse it with boiling water.
Take one teaspoon of tea for one medium cup and pour it into the teapot
Pour tea with purified water that has not been brought to a boil (about 80 degrees) and brew for no more than three minutes - this is the first brew
Pour a second time hot water, but now insist for 30-40 seconds longer than before
Such brewing of the same portion of green tea can be carried out up to 5-7 times and at the same time its properties do not deteriorate. It is said that the third brew is the healthiest and tastiest in this preparation of green tea.

Second way

To prepare tea, we use a porcelain or clay teapot and a bowl.
Pour dry tea into the teapot at the rate of one teaspoon per serving.
Pour very hot water and then insist a couple of minutes
Pouring tea into a bowl
Pour from the bowl into the teapot
We repeat this manipulation several times

With this brewing, tea "breathes" - it is saturated with oxygen and cools down a bit. After 5-7 transfers from the teapot to the bowl and back, pour the tea into cups and enjoy the drink.

They say that tea has an invigorating effect after two minutes of brewing, but if you brew it for 5 minutes, then the tea becomes soothing. If you brew tea for more than 10 minutes, you can get bitter tea leaves.

The most optimal is the use of no more than six cups of green tea a day, this contributes to the normalization of metabolic processes.

If you have eaten a lot of fatty foods, then after half an hour - an hour, drink a cup of green tea, this will help better digestion.

If a hangover torments you in the morning, then a few large mugs of strong green tea will bring you back to normal. Attention! If you have hypertension, then you can’t drink tea with a hangover! Yes and myselfabout a hangover with hypertension is unacceptable.

If you get sick on the road, chew dry tea leaves and this symptom will go unnoticed.

If you brew green tea with lemon, it will help to keep all the trace elements of tea in full and make it more useful than usual. After all, vitamin C neutralizes tannin, which prevents the absorption of trace elements and vitamins.

Harm and contraindications to drinking green tea

In addition to the beneficial properties, green tea also has contraindications, and can also be harmful.

You should not drink green tea when:

Hyperexcitability
insomnia
Tachycardia and arrhythmias

Everyone is well aware of such a tonic and refreshing drink, the benefits and harms of which are of interest to many who consume it. The attitude towards this gift of nature is often contradictory, but to deny beneficial features no green tea. Some put leaflets on a par with drugs, and some consider its consumption only following the newfangled trend of leading a healthy lifestyle. This controversy has been going on ever since green tea appeared in Ancient China. So what is the use of a wonderful drink, and what harm can it bring to the human body?

Main components

This drink is considered to be one of the most beloved by many drinks. The leaves of the camellia tea bush, first brewed in ancient China, became known as green tea and won recognition around the world. To date, the consumption of this invigorating green tea is only increasing, and its scope is becoming wider. This marvelous drink is useful for both men and women. Today, the benefits of green tea are highly valued in cosmetology and medicine, and they are also used in pharmaceuticals. So what does green tea owe its healing properties to and are there any contraindications to its use?

The tea bush has an unusual ability to absorb substances useful for the human body from the soil and synthesize them. Moreover, the chemical properties fresh leaf tea and dried, are significantly different. Dry tea leaves have a more intricate chemical composition. To understand it, you need to consider a simple tea leaf from the point of view of science, and find out which of its components have a good effect on the human body, and which can be harmful.

What green tea is useful for is the tannins it contains. Tannin occupies a special place among them; this type of tea owes its unusual taste to this substance. Useful it delicious drink and thanks to the essential oils it contains. Essential oils in the composition of tea, give each of its varieties a unique taste and aroma, and have a great influence on the quality of tea.

In addition to the listed elements, the beneficial properties of this refreshing drink are increased due to the invigorating caffeine alkaloid contained in its composition, in other words, theine. This component is found in large quantities in coffee. But in green tea, the action has a different character, it is softer, does not excite the nervous system and gently affects the cardiovascular system.

Pectins in the composition of tea contribute to the breakdown of fats, reduce the level of bad cholesterol in the blood, and therefore reduce the risk of atherosclerosis.

This drink is useful in case of poisoning, it is able to overcome many intestinal infections. The adsorbent property of green tea is able to free the body from harmful toxins. This healthy tea eliminates toxins and salts from our kidneys, thanks to a diuretic effect, thereby reducing the possibility of stone formation in bladder and kidneys.

Today, a person is everywhere exposed to the most harmful factors - solar radiation, radiation, radiation from televisions, mobile phones, and poor ecology. Unfortunately, it is almost impossible to avoid them, but it is quite possible to help the body cope with them. For example, studies have shown that daily tea consumption can reduce the risk of developing breast cancer in women by up to 90% and other types of cancer by 60%. For men, the benefit of regular consumption of this invigorating drink is to reduce the risk of prostate cancer by almost half. The benefits of green tea for men also include a beneficial effect on potency. Green tea contains zinc, which is useful for the production of testosterone, the most important sex hormone in men. Therefore, the inclusion of green tea in the daily diet is essential for men.

This tea promotes the expansion of cerebral vessels, nourishes it with oxygen and improves blood circulation. Thanks to these properties, an invigorating drink is useful in the prevention of heart attacks and strokes. It is impossible to list all the benefits of this type of tea. Especially healing properties of this beloved drink is not fully understood. This healthy tea has a complex effect on the entire body, refreshes and tones, gives good health and vigor. But still, doubts whether green tea can harm and whether there are contraindications to its use remain.

Harm

As they say, the medal has two sides. The same can be said for green tea. Let's try to find out why green tea is harmful?

The caffeine contained in tea can play a bad service. With a large use of this tea, the invigorating properties of caffeine can cause insomnia, restless sleep and irritability, heart palpitations. In addition, the harm of caffeine is that it can be addictive and the body will require its constant use. Therefore, even in the use of such useful product, like green tea, you need to know the measure, otherwise it will become harmful.

The harm of green tea can manifest itself when it is used by people with gastritis, stomach ulcers, as in a strong brewed form it can irritate the mucous membrane and cause pain. There are contraindications to drinking strong tea for people suffering from kidney stones and rheumatoid arthritis.

Is green tea harmful for men and are there any contraindications, and what is its effect on the female body? There is an opinion that there is harm to green tea for men's health, but this statement is true only with an overdose of tea. And when consumed in moderation, this tea is beneficial for both men and women. For the latter, it is still expensive for its rejuvenating properties.

To fully enjoy the taste and valuable properties this valuable product, it should be drunk no later than 15 minutes after brewing. Excessive tea is harmful for both men and women. It is contraindicated for those suffering from gout, hypertension and patients with glaucoma, since long-term infusion of tea leads to an increase in caffeine in its composition.

A few tricks that neutralize the harm of green tea and reduce contraindications to its use:

do not drink green tea on an empty stomach;

you should give up green tea before eating, so as not to reduce the taste of food;

you do not need to drink this drink immediately after eating, it will slow down the digestion process and become harmful to the digestive tract;

How to prepare green tea

Use ceramic, porcelain or glassware for brewing;

Brew tea with not too hot water - 60-80 degrees will be enough (tea will be brewed even in absolutely cold water). In order to determine whether the water has reached the desired temperature, you need to listen - bubbles in boiling water should make noise like wind in a pine forest;

The chemical composition of green tea: benefits and harms

The most complex chemical composition of a properly prepared drink helps to cope with malaise and headache, equalizes pressure and allows you to normalize metabolic processes in the body. It is possible to talk about green tea, its benefits or harms only by studying the most effective organic compounds that make up its composition.

1. Catechins and polyphenols, among which epigallocatechin gallate. In green tea, many substances bring benefits, but it is necessary to single out polyphenols separately - phytoseries nutrients that exhibit a pronounced antioxidant effect. Polyphenolic compounds help the body protect itself from the development of cancer. Polyphenols also prevent diseases of the cardiovascular system and diabetes. Green tea polyphenols are best absorbed when consumed without sugar.

Catechins benefit not only the immune system, but also metabolic processes. What do catechins do?

Remove free radicals, slowing down the aging of all vital systems;
