Whether in green tea. What are the benefits of green tea for women? Brew tea in pottery

To the sacramental question "To drink or not to drink green tea?" each of us has our own answer. For some, green tea is a real medicine, for others, a useless, not tasty drink is just a tribute to fashion.

Love for green tea, stepping over the Great Chinese wall, spread all over the world. Today, millions of people drink it in colossal amounts. Green tea is used in pharmaceuticals, medicine, and cosmetology. Therefore, it is so important to know: what is more - benefit or harm lurks in this drink?

Composition of green tea

The tea plant has amazing property. It is able to absorb from the soil and synthesize a variety of substances useful to humans. The chemical composition of fresh tea leaf and the tea leaves prepared from it are far from the same. In a dry tea leaf, it is much more complex and varied.

Let's briefly dive into the exact science of chemistry and try to talk about the benefits and harms of green tea at its respected level. Let's discuss the components of the tea leaf and their effect on the human body.

Amino acids contribute to the restoration of an exhausted nervous system. Figuratively speaking, it restores the very nerve cells that are not recoverable. Other important property tea amino acids - lowering blood pressure, but there are nuances here. In order for them to work, tea should not be drunk too hot.

There are also plenty of vitamins in green tea. In terms of vitamin P content, it surpasses oranges and lemons. Vitamin P enhances the effect of vitamin C, which is also found in tea. And, speaking as a united front, P + C seriously increase resistance colds relieve stress and fatigue.

Green gulls are rich in vitamins of group B, PP, provitamin A or carotene (long live healthy hair!). A well-known fighter against the aging process of our body, a well-deserved antioxidant vitamin E has also found its place in the chemical composition. tea drink. There are magnesium, manganese, sodium, potassium, fluorine, iodine, copper in green tea. Even gold! But they are not found in dry tea, these elements pass into the tea solution only when brewed.

There is in tea and another small group chemical components. These are resinous substances. Their role has not yet been fully studied, but it is quite obvious that they act as carriers tea aroma. And to an even greater extent - as its clamps.

The exceptional ability of tea, when brewed, to release only useful substances into the infusion, and leave the useless in an undissolved form, remains a mystery.

Green tea is an ambiguous drink. It is made from tea tree leaves that have not been fermented. Known for the rich chemical composition of green tea. What a person eats and drinks affects his health. Drinks sold in stores contain chemical substances, which are not very useful 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:

1. 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 the nervous system; vitamins A, PP, D and E.
2. 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 contributing women's health, and manganese. The minerals contained in the leaves help correct work internal organs, strengthen the immune system, maintain the balance of all body systems and normalize metabolism, which, among other things, contributes to weight loss.
3. Caffeine - well, everyone knows caffeine, its invigorating and tonic properties are familiar to coffee lovers, but with green tea everything is not so 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 drinker, suddenly began to jump pressure, my doctor recommended replacing Morning coffee green tea, and the positive experience inspired me so much that I completely switched to it. Surprisingly, the pressure returned to normal.
4. 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, determine suitable temperature pretty 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:

1. During pregnancy. It prevents natural breakdown folic acid, 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 a day can induce the birth of a child with reduced weight, stimulate premature birth with possible fetal death.
2. With unstable nervous system and in diseases of the cardiovascular tract. Of course, theine is bad for them. But tea is rich in more than just theine, it contains substances that actively affect these systems, which causes it harmful effect such as theobromine.
3. With a stomach ulcer. Rather tea contraindicated, which is really harmful. Strong tea, and green 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.
4. 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.
5. 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.
6. 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.
7. Washout beneficial trace elements. Tea removes metals from the body. Again because of theine.
8. 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.
9. 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.

• 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). To determine if water has reached 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;

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" - "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. Research has established that 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 from varying degrees Reliability 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. Best effect achieved by using high quality varieties made from 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 drinking a green drink to all healthy people to reduce the risk. 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.
