In addition, green tea acts very gently, harmlessly, improving the general condition of our body.

He helped them survive the cold winters, save themselves from the heat in the summer. Today, this invigorating drink is drunk all over the world. In Russia, it has become popular relatively recently. If we associate black tea with a samovar, home comfort, pies, then many do not consider green tea to be tea at all, at the first dose it seems bitter and devoid of taste.

Many years ago this amazing tea different varieties I was brought from China, since then I start my day with a cup of this invigorating drink, I find it unusually tasty and even the taste of the usual tea has faded in front of its green counterpart. To appreciate the taste of a drink, you need to buy a good quality goods a trusted manufacturer and most importantly - you need to be able to brew it correctly.

Many may have a question - how many calories are in green tea? Calorie-free green tea without sugar is so low that it can be considered zero, it does not contain fats, proteins and carbohydrates. So what is green tea and how does it differ from black? Let's figure it out.

Green and black tea. What are the differences?

Green and black tea are differently fermented leaves of the same plant. Fermentation is a complex labor-intensive process of processing a tea leaf, which results in one or another color, aroma and taste. To obtain the necessary qualities, the fermentation process of tea leaves is suspended after a certain time, which allows you to keep the green color and fresh aroma. In such a drink, the maximum amount of useful substances is preserved, for which it is valued all over the world.

About caffeine

Although, for the sake of clarity, it must be said that the caffeine contained in tea differs in its effect from the caffeine that is rich in coffee.

The content of caffeine in green tea depends on the place of growth of the tea bush, on weather conditions, on the time of collection, so it is always different for different varieties and varies from 60 mg to 85 mg per cup of tea.

How to drink green tea

Dear readers, the blog has articles on how to brew and how to drink green tea, where you can find detailed information on these issues.

But in short, when brewing green tea, you need to follow a few simple rules in order to get the maximum benefit from the drink.

• The teapot must be warmed up before brewing.
• Do not use boiling water for brewing, the water temperature should be about 90 degrees.
• Take a teaspoon of tea leaves in a cup of water.
• Pour a small amount of tea leaves hot water and after a few seconds drain this water. After that, finally brew tea. This is what tea connoisseurs do in China, Morocco, and Japan. By doing this, we reduce the amount of caffeine in the drink and disinfect the tea leaf.
• Do not brew the drink for too long, 1-2 minutes is enough, after which you can brew the leaves twice more, each time increasing the brewing time by a minute.
• Store tea in a glass or ceramic container with a ground-in lid, as it is hygroscopic, which means it absorbs moisture, which will adversely affect its quality.

Very often there are questions about green tea, as conflicting opinions can be found both in the press and on the Internet. Here are the main ones:

Is green tea invigorating or calming?

Very weak, repeated brewed tea is virtually devoid of caffeine, so a sedative effect is also possible. But a full-fledged, properly brewed drink invigorates, as it contains caffeine in its composition.

Green tea weakens or strengthens?

This question is often asked by people too. But the fact is that green tea does not act so monotonously, it does not have either a laxative or fixing effect, but it will be useful both for diarrhea and constipation, since the substances that make up it regulate digestion.

Can you drink green tea every day?

Here there can be only one answer - you can drink a drink every day in the absence of contraindications, but not more than 2 cups.

Harm of green tea and contraindications

All of the above applies only to moderate consumption of good green tea, only in this case we can talk about its benefits. If you drink it too often and a lot, then you can get harm instead of good.

Green tea originates in Asian countries, but over time, people all over the world fell in love with its taste.

Mineral elements are responsible for the activity of the heart muscle, they enrich the blood and stabilize the pulse. Minerals affect metabolic processes, significantly accelerating them.

Theine is a well-known invigorating element, an analogue of caffeine. There is about the same amount of caffeine in green tea as there is in medium-brewed coffee. Green tea in the morning invigorates no worse. It stimulates the neurons of the brain, awakening and energizing for the whole day. Theine has a much milder effect on the body, unlike caffeine.

The drink accumulates a lot of catechins, which belong to the flavonoid family. These natural antioxidants cleanse the cavity of internal organs from radionuclides, free radicals, toxic substances and slagging. Against the background of complex cleaning comes a comfortable weight loss without stress for the body.

Green tea and weight loss

Green tea for weight loss is very effective - it helps to speed up the metabolism. It is this tea that is the most effective for weight loss among other varieties of tea: it is able to improve the metabolic process, remove toxins from the body. In a fairly short time, you can easily, and most importantly, without harm to health, lose weight naturally.

How to lose weight with green tea:

1. If you want to lose weight in a short time, then green tea will help you, which has a diuretic effect, making it easy to remove excess fluid from the body. In order to enhance this effect, you can add a little skimmed milk to the tea.
2. Tea should be drunk about 3-5 times a day, while sweeteners or sugar should not be added to tea. To enhance the effect, it is necessary to reduce the consumption of fatty foods, do not eat late at night. It is best to drink tea a little cool, this is necessary so that the body heats it up on its own and at the same time spends additional calories.

3. Remember that if you want to arrange a fasting day for yourself, then throughout the day you need to drink not only green tea, but also water, at least 1.5 liters. This will help restore water balance and remove toxins from the body.

Green tea during pregnancy

If you are wondering if green tea is possible for pregnant women, then the unequivocal answer is yes, but in limited quantities. After all, green tea is a source of additional vitamins and minerals, such as magnesium, iron and calcium, which are often not enough for pregnant women.

Green tea during pregnancy is very useful, but it is best not to abuse it, because it creates additional stress on the kidneys, which is why you should drink no more than three cups a week.

Green tea during pregnancy has a positive effect on the immunity of a woman and a child, it normalizes the functioning of the heart, maintains sugar levels in the body, while being a preventive measure against diabetes in mother and child.

Numerous treatises of Chinese philosophers and Indian healers are devoted to green tea, this drink has many unique properties and is used as a medicine for some 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.

That's why green tea cannot 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. We, again, are talking about a very 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 of the nervous system, and those who are prone to frequent mood swings. You should not drink it at night, even for healthy people - often it is he who causes insomnia.

With caution, green tea should be consumed by those who have problems with the 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, cardiovascular and nervous system, and then the kidneys “join” them.

The stimulating effect of green tea, multiplied by a hangover syndrome, can even lead to a heart attack, not to mention neurosis, and 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. In addition, the frequent use of alcohol in combination 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 do not have high acidity, but at the same time even a small cup of this drink causes heartburn, then 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 they buy tea dust, garbage and small crumbs left after the packaging of high-quality tea, “hide” it in bags and attract buyers at 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 a manufacturer's attempt to increase the price, but the best storage method. 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.

This drink is especially widespread in Asia. The Chinese and Japanese probably cannot imagine life without it. In our country, he also pays a lot of attention. Adherents of a healthy lifestyle especially revere green tea, because it has a lot of valuable properties. To learn more about them, read on!
