Depending on the treatment, a green or black variety of the popular drink is obtained from the tea bush. Green tea is useful in the ability to quickly quench thirst, stimulate digestion, reduce fat deposits, have a restorative and tonic effect, improve and maintain a wonderful mood throughout the day. Drink is contraindicated and can be harmful if consumed excessively, improperly brewed.

Varieties

All kinds of green tea are made from tea bush. For the preparation of some varieties, buds and young upper leaves are used, while others are ripe greens.

The tea bush is small - about a meter in diameter and a half meters high. The plant is whimsical, requires careful care. When creating favorable conditions, it grows rapidly, gives a yield of leaves twice a month.

Quality varieties are produced exclusively from the leaves of the first crop, in subsequent harvests less useful properties.

Green teas, which grow in China and Japan, bring maximum benefits to the body. They are inferior to the products of Ceylon, Java, India.

Compared to black tea, the green variety is obtained by more gentle processing, as a result, parts of the plant are preserved and more active compounds are released during brewing, therefore green tea is healthier.

Oxidative processes are stopped by treating the crop with steam for 2-3 minutes. As a result, the aroma of fresh leaves is eliminated, they become soft and lethargic, prepared for subsequent twisting. After steaming, the plant material is held in air for some time to eliminate excess moisture.

Twisting is performed on special equipment. The machine wrinkles and rolls up raw materials, which allows you to remove residual moisture and give the particles one form or another. At the end of the twisting procedure, the product takes on the familiar look.

It is believed that the more the tea leaves are twisted, the longer the beneficial properties of tea are preserved, the stronger it is brewed.

• Almost non-twisted varieties are called "unchi". They look like grass.
• Twisting across the fibers gives the product the appearance of flakes or balls, these are the so-called "pearl" varieties.
• Twisting along the fibers turns the tea leaves into spirals or sticks.

The final stage is the final drying of the leaves, which allows to stabilize the aroma and nutrients. Removing moisture residues is done by drying or roasting:

• during drying, the raw materials are not mixed. The finished product has a dark green color, soft taste.
• during frying, the mass is constantly interfered, it becomes bright green, with a rich aroma and wonderful taste.

The finished product better retains its beneficial properties in opaque sealed packaging, but not in film.

Depending on the size of the tea leaves, the following varieties are distinguished:

• large-leaved, distinguished by quality and high cost;
• small-leaved, more affordable, but less tasty and aromatic;
• powder, it is used together with tea leaves, it is in demand among gourmets. To brew, the powder is placed in a cup, poured with hot water, beat until foam.

Composition

A green drink is useful for invigorating and stimulating properties due to caffeine. In “tea” terminology, this purine alkaloid and at the same time a psychostimulant is called thein. Thus, caffeine and thein are identical.

Tea contains catechins, tannins, and strong antioxidants. Tannin, an isomer of one of the kakhetins, is useful for inhibiting the activity of pathogenic microorganisms.

Varieties of green tea are useful oncoprotective properties, due to the epigallocatechin gallate included in their composition.

Animal experiments have confirmed that this type of catechin destroys free radicals, prevents cell damage, and reduces the size of tumors.

The combination of thein and tannin forms caffeine tannate, which gives the tea its characteristic taste and aroma, and slows down the absorption of caffeine. Therefore, in comparison with coffee, it has a softer invigorating effect.

Due to the gentle processing of plant materials in green tea varieties, thein content is higher than in the black variety. Its highest concentration is in young leaves and buds. In mature leaves, thein and tannins are less.

The green drink contains vitamins A, groups B, P, PP, K, C, they are stored almost in full after technological processing.

Green tea is useful in high content of vitamin P (routine), which helps in strengthening blood vessels and capillaries, normalizes metabolic processes, is important for biochemical cleaning of the gastrointestinal tract, liver, and kidneys.

Trace elements are represented by copper, potassium.

The composition includes up to 20 percent of tannins, essential oils, flavonoids.

In combination with caffeine, theophylline, nicotinic and pantothenic acids, these substances are useful tonic, stimulating effect on various body systems, improve heart function, the state of the vascular walls, brain nutrition, support normal blood coagulation.

Green tea is useful in its high content of antioxidants, so its regular use is a means of preventing the development of tumors.

The drink has a fat burning effect that is used in weight loss and weight loss programs.

What is green tea good for?

For greater benefit, green teas are brewed and drunk with. Tea tannin prevents the absorption of trace elements, vitamin C, which is part of the lemon, neutralizes the effect of tannin.

Research has confirmed that green tea lowers bad cholesterol.

Green tea does not cause allergic reactions.

How to make green tea

It will require clean, soft water, which should not be brought to a boil - boiling water affects the taste, aroma and beneficial properties of the drink. Insist not for long, 3-4 minutes.

Green tea is drunk very hot, carefully taking small sips, savoring and enjoying, diluting it with cold water reduces the benefits. The addition of sugar is allowed, but it is much more pleasant to enjoy the natural taste and aroma of the drink.

One serving of a high-quality grade can withstand several brews, so it is better to use a small kettle.

The recipe for proper brewing of green tea:

• Rinse the teapot with boiling water.
• Place the tea leaves at the rate of 1 tsp. on a glass.
• Pour hot boiled water 80-85C.
• After a couple of minutes, pour the finished tea into the so-called "chahai", a fairly roomy dish, from which it is then poured into cups.
• Pour hot water into the teapot again, insist for 30 seconds longer, pour the finished drink into the chahai.

Quality varieties of green tea retain their beneficial properties even after 7-10 brewing cycles. Dishes should not be metal or plastic, the best material is clay.

Another simpler recipe that uses a bowl and teapot:

• Pour tea leaves with hot water, as in the previous recipe
• After two minutes, pour the drink into the bowl, then back into the kettle.
• Repeat several times so that the tea mixes, cools down a bit, "breathes".
• After the tea has been infused for a while in the kettle, you can drink it.

The drink should not be bitter, otherwise it is a sign of over-brewing.

It is believed that tea in 2 minutes after brewing has an invigorating effect, after 5 minutes - soothing. During the day, do not consume more than 5-6 cups.

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 "increased pressure in the system."

The increase in blood pressure to 140/90 mm Hg not always associated with increased vascular tone. High values \u200b\u200bcan be observed with their usual and even reduced tone due to an increase due to various reasons of cardiac output.

Therefore, discussions about the benefits of green tea varieties to lower or increase pressure continue.

According to one point of view, there is no change in indicators. The caffeine that is part of 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 tone, as a result of which the indicators quickly return to normal.

Studies have found that a green drink is useful in its ability to thin the blood, it becomes more fluid. As a result, the load on the heart muscle is significantly reduced, pressure indicators are normalized, and the risk of stroke decreases.

Other studies with varying degrees of confidence confirm the benefits of green tea to reduce the level of "bad", 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 by consuming high-quality varieties made from upper young leaves.

Green tea varieties are useful as a diuretic, so they are used in the treatment of cardiovascular or renal diseases, and reducing swelling.

The results obtained allow us to recommend a healthy drink to all healthy people to reduce the risk of hypertension, as well as in the initial stage of this disease. Many patients note a normalization or a noticeable decrease in indicators, an improvement in their condition. But to talk about the complete cure of the disease in this way is not necessary.

To draw a more definite conclusion about the benefits of green tea for regular use, additional years of research are required.

Slimming green tea

Having decided to lose 2-3 kilograms, it is useful to consume a green drink several times a day. To diversify the taste helps a slice of lemon, 1-2 dried fruit, mint leaf.

In a simple one-day diet, a weight loss recipe is based on taking 2-2.5 liters of milk during the day:

• Brew a glass of milk 1 tsp. green tea or make tea in the usual way and drink it with milk.

The resulting diuretic effect helps to quickly get rid of one or two kilograms.

Healthy green tea should be included in any low-calorie diet lasting from 7 to 10 days:

• Brew and consume 5-6 times a day an hour before meals or an hour or two after meals, once a day - with milk.

Include fruits, vegetables, berries, dairy products, lean meat, fish in the diet. To completely refuse sugar, replace it with a small amount of honey. In a day or two, cook buckwheat porridge.

How it is grown and what properties it has. But this tea gained such popularity not by chance. The rich composition of the tea leaf, the features of its production make it a very valuable product.

What is contained in tea

Looking at a green tea leaf, it is hard to believe that it contains more than 2000 chemical constituents. Most are good for human health. The components of tea can affect the state of the body. Not without reason in China, the birthplace of this drink, for several centuries it was used only as a remedy. He entered the daily diet much later. Consider the chemical green "under the microscope" to understand what elements make the drink so useful.

Green tea does not undergo the fermentation process, so all the healing substances that could be destroyed by oxidation remain in the tea. The main chemical elements that are in the tea leaf include:

• catechins
• theanine;
• amino acids
• vitamins
• caffeine,
• essential oils,
• minerals.

Sweetness and taste are given to the drink by amino acids and theanine, bitterness by caffeine, and astringency by catechins. The taste of tea can determine which substances in a particular variety are more.

Catechins - what is it

Strong polyphenols and flavonoids belong to this group of substances. They are powerful antioxidants that are characteristic of weakly fermented teas. Studies conducted by scientists have shown that tea’s catechins owe its protective properties. There are four components of tea catechin: EGCG, EC, EGC, ECg. Epigallocatechin gallate is considered the strongest. It is almost a hundred times greater than the power of vitamins E, C and β-carotene.

One cup of green tea is much healthier than broccoli, carrots, spinach, apples, because it contains up to 40 mg of polyphenols. Catechins easily adhere to proteins, preventing viruses from destroying cells. They are also able to counteract toxins.

Scientists from the American National Cancer Institute have proven that catechins can cleanse the body of oxidizing agents before they harm cells and lead to tumors. The high antioxidant activity of catechins contained in green tea is very much appreciated. Nutritionists around the world use green tea in their programs. It is the best natural fat burner.

Catechins help with various diseases:

• destroy free radicals;
• eliminate inflammation of the gums, oral cavity;
• inhibit aging;
• improve bowel condition;
• reduce cholesterol;
• help with radiation exposure.

For comparison: about 100 mg of caffeine in the same cup of coffee. Thanks to caffeine, green tea affects a hangover, removing alcohol from the body. Tea made from young leaves contains more caffeine than old leaves, but also more theanine, which neutralizes the effect of caffeine. Caffeine has diuretic properties, drives away sleep, eliminates headache, has a stimulating effect on the central nervous system, and accelerates blood circulation.

The action of minerals

Minerals are necessary for normal development, they activate enzyme systems, interact with vitamins, hormones. Green tea contains up to 7% of minerals, including phosphorus, copper, manganese, calcium, potassium, zinc. Copper and zinc are elements for the formation of antioxidants. Minerals control the water balance, give strength to the skeleton, maintain balance in the body.

The effect of vitamins on the body

Green tea contains many vitamins of different groups. Each of them contributes to the common cause of improving the human body and maintaining it in excellent shape. Vitamin P is needed to protect cells, strengthen blood vessels. It helps to reduce pressure, normalize the function of the thyroid gland.

Vitamin A or carotene improves eyesight, strengthens the immune system, supports the condition of the hair, helps prevent aging. Scientists have discovered several types of carotene in tea leaves, of which β-carotene predominates.

Vitamin B1 or thiamine quickly relieves fatigue, improves mood, improves brain function. Necessary to improve metabolism. Since the supply of vitamin in the body must be constantly replenished, you need to drink several cups of green tea per day.

Vitamin B2 or riboflavin improves skin condition, improves eyesight.

Vitamin B3 or nicotinic acid lowers cholesterol, helps control sugar levels, and improves digestion. Niacin is essential in the formation of red blood cells.

Vitamin C has anti-inflammatory and antibacterial properties. It affects the synthesis of hormones and prevents colds.

Vitamin E or tocopherol helps in the fight against infertility, it is important for the heart, skin. It is also called the fertility vitamin. Acts as an antioxidant.

Vitamin F or fluoride helps relieve swelling, strengthens teeth, heals wounds. In green tea, its content exceeds 40-1900 ppm. In young buds it is less than in mature leaves.

Vitamin K strengthens the skeletal system, increases life expectancy, removes toxins from the liver, and has an antibacterial effect. Green tea leaves have a high concentration of vitamin, but when brewed, most of them disappear.

Vitamin U normalizes acidity, prevents obesity of the liver, controls cholesterol. In high-quality tea, this vitamin creates a special aroma reminiscent of dry seaweed.

Thus, it should be understood, green tea increases or decreases pressure and what is the physiology of the process.

It is necessary to start with the fact that all experiments were conducted on healthy people, for this reason it is difficult to say that a particular drink can normalize abnormal blood pressure. A specific tea indirectly affects the level of pressure, because after its use the overall picture does not actually change.

The peculiarity of the effect of the drink on the cardiovascular system is that the caffeine contained in tea accelerates the work of the heart, and accordingly increases the volume of liquid tissue passing through it. In this case, the enzymes of the drink act on the vasomotor center in the brain, due to which the vessels expand. Thus, changes in pressure practically do not occur.

Diabetes Benefits

Diabetes mellitus is a complex disease that is characterized by an increase in blood sugar. It is impossible to recover from this disease, since it is a chronic process caused by metabolic disorders. In diabetes, it is extremely important to pay attention to the consumed foods, as diet is the main way to control the level of sugar and, accordingly, well-being.

As for green tea, it would be ridiculous to say that it can be cured of a specific ailment, but this drink can serve a good service to a person with diabetes. The fact is that it is green tea that increases the body's sensitivity to insulin, and accordingly prevents the development of dangerous conditions with high sugar levels.

The healing properties of gastritis and pancreatitis

Gastritis and pancreatitis are quite complex diseases in which the main treatment method is diet. Nutrition in this case is a key tool for regulating metabolic processes, which directly affect the patient's condition with one of these diseases. It is also immediately necessary to note that green tea in the described situation is far from always possible.

Indeed, a particular drink has a positive effect on digestive processes, as it improves the production of digestive enzymes. Thus, drinking a cup of tea daily can improve the release of bile into the intestines, which is especially important for pancreatitis. As for gastritis, in this situation it is necessary to be careful, since the substances contained in both green and black tea increase the acidity of gastric juice and can aggravate the situation. For this reason, drinking green tea during an exacerbation of gastritis is not recommended.

Effect on the prostate

One of the most unpleasant diseases for the male body is prostatitis or inflammation of the prostate gland. This gland is responsible for the removal of ejaculate through the urinary canal and in case of inflammation, there is a violation of the urogenital function. This disease is quite difficult to treat and in most cases goes into a chronic form.

In the period of exacerbation of the disease should be especially careful about their own health, including diet. Green tea has anti-inflammatory properties, so the drink can reduce the risk of developing the described problem. However, most men do not know whether this drink is a diuretic or not, which should be considered first.

Due to the fact that tea has a pronounced diuretic effect, it should be discarded during an exacerbation of the disease. This information can also automatically answer the question of whether it is possible to drink green tea at night. Given all of the above, we can conclude that green tea can indeed be an excellent prophylactic against prostatitis, but you should not count on it in case of exacerbation of the disease.
