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 that are sold in stores contain chemicals that are not very good for the body.
What drink can not be doubted for a long time - 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 the 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 contributing women's health, and manganese. Minerals contained in the leaves help to work properly 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 in more than just theine, it contains substances that actively affect these systems, which causes it harmful effect such as theobromine.
- With a stomach ulcer. Rather tea contraindicated, which is really harmful. Strong tea, and green tea in particular, increases the acidity of gastric juice, and this, in turn, prevents natural process 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.
- Washout 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 emits 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
Beneficial features green tea has long been used in Asia - China, Japan, Central Asian peoples use this "health cocktail" every day: 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.

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. 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, 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.
In order to draw a more definite conclusion about the benefits of green tea for reducing blood pressure in regular use, additional long-term studies are required.
Green tea with milk
Maybe, healthiest 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 useful feature green tea in bags with milk - it has an alkaline environment (thanks to milk), which means it is able to 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 bring green tea maximum benefit, 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.
Numerous treatises by Chinese philosophers and Indian healers are devoted to green tea; this drink has many unique properties and is used as a medicine for certain diseases. It perfectly tones, breaks down animal fats, promotes digestion. After all, it's just delicious.
But is it as useful as we used to think? And can a cup of green tea hide not only the elixir of youth and health, but also poison?
Harmful properties of green tea
To begin with, green tea is considered a powerful antioxidant these days, but the actual benefit of oxidation inhibitors is questionable. Numerous studies prove that excessive consumption of antioxidants does nothing but harm - various diseases begin to develop, the body ceases to resist certain types of bacteria.
Therefore, green tea should not be abused. If you drink 5-6 small cups a day, then you won’t harm yourself, but those who drink more than 1.5 liters of strong brewed tea automatically fall into the risk group.
Green tea also adversely affects the nervous system. Again, we are talking about rich drink. In concentrated form, it provokes nervous overexcitation, because it contains much more caffeine (theine) than coffee itself.
So strong green tea is not recommended for those who suffer from any diseases. nervous system and those who are prone to frequent mood swings. You should not drink it at night, and even healthy people- often it is he who causes insomnia.
Caution should be taken with green tea for those who have problems with cardiovascular system, in particular, people suffering from tachycardia and arrhythmia. The substances contained in this drink provoke a rapid heartbeat, which can not only exacerbate diseases, but also cause heart rhythm failure.
What is harmful green tea
In addition, green tea irritates the stomach lining, so you should not drink it on an empty stomach. The fact is that it promotes digestion, which means it enhances the production of gastric juice, and if the stomach is empty, it begins to digest itself, respectively, erosion occurs that can turn into ulcers.
Especially do not drink green tea on an empty stomach for those who already have gastritis or an ulcer. Many sources write that this wonderful drink prevents these diseases, but here, as with poison, it all depends on the dosage and time of administration.
Therefore, at times of exacerbation of chronic gastric diseases, it is recommended either to completely abandon the use of green tea, or to drink it in a not very concentrated form after meals. Then it will really be a medicine and will not provoke a relapse.
Green tea and alcohol
Many believe that a cup of green tea, drunk in the morning, helps to cope with a hangover, because it allegedly removes toxins. However, it is not. The external and momentary effect of relief is incomparable with the harm that is done to the body. First of all, the cardiovascular and nervous systems suffer, and then the kidneys “join” them.
The stimulating effect of green tea, multiplied by hangover syndrome, can even lead to a heart attack, not to mention neuroses, well, renal colic is also not a very pleasant thing. By the way, it is impossible to mix green tea with alcohol not only in the morning - during "libations" this mixture also has a bad effect on the body. Yes, and toxins are not excreted, but, on the contrary, are formed.
In addition, both alcohol and green tea have a diuretic effect, so their combination leads to a sharp dehydration of the body, and this, in turn, leads to nervous excitement, aggression, and then to a decrease in vitality. Besides, frequent use alcohol combined with green tea accelerates skin aging.
Green tea and blood pressure
We often hear that green tea actively affects blood pressure. Surprisingly, both hypertensive patients and hypotensive patients write and talk about it. Someone complains that low blood pressure is getting even lower, someone - that high blood pressure jumps sharply to terrifying levels. But there are also those who speak with gratitude about this drink - in some it increases the low, in others it reduces the high. Which of them is right?
As it turns out, the truth is somewhere in between. For those on whom green tea has a positive effect, it simply regulates the pressure, that is, it raises or lowers it to an acceptable norm by the body. Those who, after drinking, suffer from too low or from excessively high blood pressure, belong to people with a personal intolerance to this drink.
So if after a cup of green tea you feel a breakdown or the back of your head starts to hurt, then this drink is not for you. Do not experiment, but abandon it in favor of teas and infusions, after which you do not experience discomfort. Or at least reduce the dosage or make a weak tea solution.
Green tea quality
What is harmful green tea
Absolutely healthy people should also pay attention to their well-being after drinking green tea. If you don't have hyperacidity, but at the same time, even a small cup of this drink causes heartburn, which means that you have purchased low-quality raw materials.
Remember that in regions where there are no tea plantations, tea, by definition, cannot be very cheap, because not only processing and packaging costs, but also transportation costs are required. Unscrupulous manufacturers often purchase tea dust, garbage and small crumbs left after packaging. quality tea, "hide" it in bags and attract buyers with a low price.
It is best to buy tea from trusted brands, and not in bags, but in bulk. It should not contain foreign impurities, unless it is provided for by the type of tea, that is, if it is not flavored with flower petals, zest or berries.
If you still prefer tea bags, then get the packaging, in which each of the bags is sealed in foil. This packaging method is not an attempt by the manufacturer to increase the price, but best method storage. It allows you to save all the flavors of tea and its beneficial properties.
Proper brewing of green tea
Incorrectly brewed green tea can also cause harm. Everyone knows perfectly well that a tea leaf that has not undergone fermentation can be poured with water 3-4 times. After the second brew, it only begins to truly open up and give off its taste and aroma. However, at the same time, few people think that the "life" of green tea is short-lived.
