Today we will tell you about whom green tea is contraindicated. In addition, from the presented article you will learn what composition this product has and what healing properties it has.
general information
Before we tell you who green tea is contraindicated for, we should tell you about this drink in more detail.
Green tea is tea that has undergone minimal fermentation (i.e. oxidation). At the same time, few people know that both green and black drinks are obtained from the leaves of the same tea bush. Then what is the difference between them? The fact is that the leaves for obtaining the mentioned teas are obtained in completely different ways. Without going into details, I would like to note that the raw materials for the green drink are pre-oxidized by 3-12%.
Green tea: benefits, composition
We will present the properties, contraindications and harm of this drink a little further. Now I would like to tell you about its chemical composition. After all, it is the elements included in it that determine its benefits for the human body.
Tannins
Answering the question about who one cannot help but say that a third of this product consists of various compounds of polyphenols, tannin, catechins, as well as derivatives from them. Moreover, these substances are contained in this drink twice as much as in black. That is why it should be included in your diet for those who regularly suffer from constipation and other intestinal problems.
It should also be noted that the combination of caffeine with tannin forms the substance caffeine tannate. It is this that has a stimulating effect on the cardiovascular and nervous system.
Alkaloids
Contraindications of green tea, as well as benefits, are determined by its composition. As we found out above, this drink contains caffeine. Typically, its amount is approximately 1-4%. Its exact content depends on many factors (for example, the size of the tea leaves, processing method, growing conditions, brewing water temperature, etc.). In addition to caffeine, this product also contains other alkaloids in the form of theobromine and theophylline, which promote vasodilation.
Enzymes and amino acids
If we talk about the presence of carbohydrates, fats and proteins in green tea, then it only contains substances such as enzymes and amino acids. Moreover, the best composition is observed in the Japanese variety.
Calorie content of the product
What else is remarkable about green tea? The benefits and harms for weight loss are also determined by the composition of this product. It should be noted that green tea is a low-calorie product. In this regard, it can be included in your diet even for those who are overweight.
Experts say that without the use of granulated sugar it is close to zero. In some cases, it can equal about 10 calories in one small cup. Therefore, you can safely brew delicious and healthy green tea for your family.
The benefits and harms of green tea
The benefit of this product is that it contains many useful substances. For example, green tea leaves contain four times more C than citrus fruits. Moreover, these substances mutually enhance each other’s healing properties. They protect cells from destruction and also help strengthen the immune system.
It should also be noted that green tea includes such an important vitamin as vitamin A (or carotene). As is known, this substance has a beneficial effect on vision and also enhances the removal of free radicals.
B vitamins occupy a very important place in this drink. Thus, B1 helps regulate the body’s carbohydrate balance, and B2 fights viruses and bacteria, and helps strengthen hair and nails. As for vitamin B3, it reduces cholesterol and enhances the production of red blood cells.
Among other things, green tea is very rich in vitamin E, which strengthens cell membranes and has an antioxidant effect on the human body. It also has a positive effect on the reproductive system - both men and women.
What is the harm?
Why some people are not recommended to include it in their diet is closely related to the composition of this drink. After all, it contains a lot of substances that contribute to the dilation of blood vessels. In this regard, it should be taken with caution by those who have any problems in this area.
Contraindications for use
For whom is green tea strictly contraindicated? Few people know, but the presented drink is allowed to drink by a fairly small number of people. This is due, first of all, to the fact that it is very rich in minerals and vitamins.
So, let's look at the contraindications of green tea in more detail:
How not to drink green tea?
Now you know for whom green tea is contraindicated. However, it should be noted that before purchasing this product, you need to pay attention not only to its harm, but also to how it should be used correctly. After all, even in the absence of contraindications, improperly drunk tea can cause significant harm to the human body.
Brewing process
The preparation of any tea drink, including green tea, is called brewing. To do this, take about 2 g of dry matter and pour it with about 100 ml of boiled water.
It should also be noted that the brewing process may vary markedly depending on what brand of product you purchased. For example, high-quality tea uses a large amount of dry leaf, which can be brewed several times over a short period of time.
The preparation time of the drink and the temperature of the water are also different for different types of tea. The highest brewing temperature is 81-87°C, and the longest brewing time is 2-3 minutes. As for the smallest value, it is 61-69°C and 30 seconds, respectively.
As a rule, low-quality tea is brewed at higher temperatures and for much longer than high-quality tea. It is from this observation that you can determine what product was sold to you in the store.
Finally, I would like to add that if green tea is brewed for too long and in boiling water, it will become astringent and bitter, regardless of its variety and quality.
Green tea is recognized as the first of 10 foods that promote health and longevity. Minimal processing of this type of tea preserves most of the vitamins, minerals and other bioactive substances that affect all organs and systems of the human body.
The ability of tea to strengthen the immune system, relieve cerebral vascular spasms, activate the heart, improve sleep, strengthen the nervous system, relieve depression, increase sexual energy and fight excess weight has been scientifically proven. The mechanisms of the anti-cancer and anti-radiation effects of tea remain unexplored, but the benefits of tea in these cases are undoubted. It is possible that tea helps prevent cancer by purifying the blood and strengthening the immune system. The anti-radiation effect of green tea is eloquently demonstrated by the fact that residents of Hiroshima, who regularly drink several cups of green tea a day, not only survived the explosion, but also improved their condition. Japanese green tea has the ability to absorb and remove strontium-90 from the body, even if it has managed to be deposited in bone tissue. By the way, a modern person, surrounded by radiation from a computer, TV and other devices and inhaling city air, simply needs regular consumption of green tea, which has such valuable properties.
In addition to normalizing the functioning of the body, green tea is also a powerful spiritual stimulant. This is why green tea and oolong tea are used in the Chinese and Japanese tea ceremony. During the ceremony, tea promotes maximum concentration and openness to new ideas. There are often cases when, over a cup of tea, an understanding of a problem comes and a completely non-standard solution to it. High-quality tea is a mild psychostimulant that regulates mental processes without causing harm to the body. With regular consumption of green tea, vision sharpens and the susceptibility of the nervous system increases, reaction speed increases, the thinking process accelerates, the ability to concentrate for a long time increases and creative activity is stimulated.
Tea makes us resistant to stress and helps improve mood during depression. All this can also be explained by cleansing the blood of toxins, but it is much more pleasant to realize that together with tea we are pouring into ourselves a mysterious, magical essence. Tea connoisseurs note that conversations over tea are different from everyday conversations and reveal the best side of the interlocutor. However, only fresh and properly prepared tea has such wonderful properties.
Despite the fact that tea packages indicate a shelf life of one to three years, three-year-old tea is much inferior in taste and beneficial properties to fresh tea. When buying tea, you should make it a rule to look at the production date. The information on the packaging will help you avoid another problem - flavorings. The very fact that “natural-identical flavorings” had to be added to green tea makes one wonder about its quality (or age). Even if the tea contains additives such as jasmine, hibiscus, chrysanthemum, pieces of fruit, lemon zest and other beautiful things, it is better to check the information on the packaging. Perhaps these additives only cover up the use of flavorings.
One should not assume that green tea is a new and unusual product for Russia. Green tea was popular in Russia long before Europe learned about it. Only in the 19th century, following the English fashion, did Russians switch to black tea en masse. The love for black tea and the established traditions of preparing it “in Russian” often make it difficult to realize the fact that black tea is made from the same tea leaves as green tea, but undergoes additional processing, which makes it less healthy.
The most common mistake when brewing green tea is using the “traditional Russian method,” in which the tea is prepared in advance in a large teapot, infused for a long time, diluted with boiling water to taste and flavored with sugar. The taste of black tea is difficult to spoil by improper preparation, so this economical method seems to many to be the only correct one. Green tea is smoother and richer. It requires special attention. It is not surprising that green tea has so few admirers in Russia - it is quite difficult to enjoy the bitter liquid of a cloudy yellow color with a pungent odor... In addition, with this method of brewing, tea loses all its beneficial properties and even acquires harmful ones. It is completely pointless to force yourself to drink improperly prepared tea in order to lose excess weight.
To enjoy green tea, you need soft water without any foreign odors. Under no circumstances should you bring water to a boil, even when brewing black tea. Green tea is much finer than black tea, and too hot water will destroy its taste, aroma and beneficial properties. 80-85C is the ideal water temperature for green teas. It is best to infuse tea in a small clay teapot. It is difficult to make recommendations on the number of tea leaves and steeping time because it depends on the type of tea and when it was picked, the softness of the water and personal preference. To begin with, you can brew one teaspoon of tea per 100 ml of water; if the taste is not bright enough, next time increase the dose.
The taste properties of each tea are determined experimentally. It takes a lot of experience and special knowledge to prepare unfamiliar tea correctly the first time. The only thing to remember when preparing green tea is that its infusion time should not exceed 10 seconds. (Sure, you can follow the package directions and brew for 3-4 minutes, but who likes the results?) Many green teas become bitter even after steeping for 3-4 seconds. Diluting tea with water negates its beneficial properties. Adding sugar equates tea to compote, which in itself is not bad, but makes no sense, especially if the tea is expensive. High-quality teas can withstand up to 15 repeated brews. This is why the teapot should be small.
With all its advantages, tea also has contraindications: excessive sensitivity to caffeine and caffeine dependence. Sensitivity to caffeine can be individual, which is very rare, and situational: with exacerbation of a stomach ulcer, hypertension, kidney disease, glaucoma, psychasthenia and any diseases accompanied by high fever. If you have a cold, you should drink weak green tea. Green tea in large quantities is not recommended for pregnant or breastfeeding women, but several cups of high-quality tea per day will be beneficial. Young children are very sensitive to tea. Children under 10-12 years old should not indulge in strong tea, but a weak infusion of green tea will provide the child’s body with vitamins and other beneficial substances.
Tannins are the most essential components of green tea. They are a mixture of about thirty polyphenolic tannin compounds, catechins and their derivatives. Tea tannins have a bactericidal effect and also stimulate the cardiovascular and nervous systems. Contains green tea and alkaloids, the most famous of which is caffeine. Due to the high content of these compounds, green tea is not recommended to drink at night.Green tea is rich in vitamins, microelements and minerals. The high content of vitamins P and C helps improve immunity, vitamin A has a beneficial effect on vision, B vitamins regulate carbohydrate balance, help fight pathogenic bacteria, and have an antioxidant effect on the body. Calcium, fluorine, iron, potassium, iodine, zinc and other substances make green tea a real treasure trove of medicinal properties.
What are the benefits of green tea
Green tea is beneficial for many cardiovascular diseases. It strengthens and tones blood vessels, prevents their narrowing, reduces cholesterol levels in the blood and normalizes blood pressure. This drink also helps in the fight against diabetes - it improves sugar metabolism and has a beneficial effect on the functioning of the pancreas.The strong antioxidant activity of green tea and its high polyphenol content help protect humans from genetic mutations and cancer.
A green tea drink is doubly valuable for women - it helps them maintain youth and beauty. Lotions, masks, and compresses with green tea significantly rejuvenate the skin and smooth out wrinkles. 3-4 cups of green tea a day help to gradually lose weight by removing excess fluid and toxins, speeding up metabolism and reducing appetite.
Green tea should be consumed with caution for joint problems such as rheumatoid arthritis and gout, kidney disease, duodenal ulcers, glaucoma, arrhythmia, and exacerbation of gastritis.
How to brew green tea correctly
For the tea drink to bring maximum benefits, it needs to be brewed. It is best to take spring water for tea. There is no need to boil it - heat the water until bubbles form at the bottom of the kettle and cool to 70-80 degrees. The teapot for green tea should be made of clay. Warm it with boiling water, pour in tea, pour in the first water and drain it immediately. Then pour the second water over the tea and leave to steep. The brewing time for green tea is individual for each variety; information about this can be found on the tea packaging.There are so many people, so many opinions about the benefits of tea. Green tea, gives us not only the pleasure of aroma and taste, but is a medicinal product. Green tea has a beneficial effect on all human systems and organs, acts gently and harmlessly, stimulates the immune system, helps fight obesity, prevents cardiovascular, kidney diseases, and so on... In addition, green tea has a beneficial effect on sexual activity, relieves vascular spasms brain, relieves depression.
Difference between black and green tea In the technology of collecting and processing tea leaves, green tea, unlike black tea, is not fermented, so the beneficial substances remain unchanged in it.
Scientists explain the healing properties of tea by the richness of its chemical composition. Currently, 300 chemical substances that are part of the tea leaf have been identified; many of the constituent compounds have not been deciphered.
In addition, the chemical composition of tea is not constant; it changes during the growth of the tea bush and during the processing of tea leaves. Many nutritionists prefer green tea, and this is due to the fact that green tea does not undergo fermentation and has the exceptional ability to release only useful components into the solution, while useless and harmful substances remain in an undissolved state. Conclusion: infusion of high-quality green tea- a concentrate of the most valuable flavoring, medicinal and dietary substances.
The tonic effect of green tea is associated with the presence of caffeine, and its concentration in tea leaves is higher than in coffee, and the effect is milder, and is associated with the combination of caffeine with tannin (a substance that stimulates mental and physical performance). In addition, tea caffeine does not accumulate or remain in the human body even with very frequent tea consumption. In addition to caffeine, green tea contains alkaloids that have a vasodilating and diuretic effect.
Green tea contains more than 300 different substances- carbohydrates, proteins, microelements, vitamins C1, B1, B2, V3, B5, K, P. In addition, green tea contains calcium, magnesium, iron, manganese, sodium, silicon, phosphorus and its compounds.
Most scientists are inclined to conclude that green tea prevents diseases of the coronary arteries, especially in the fair half of humanity.
Research by Dutch scientists has confirmed that daily consumption of 1-2 cups of tea reduces the risk of aortic atherosclerosis by 46%, and consumption of 4 cups by 69%.
Drinking green tea daily helps fight excess weight. An especially nice detail: unsweetened tea contains no calories! And it helps you lose weight. Tea accelerates metabolic processes occurring in the body. And if the reason for excess weight is a decrease in the body’s metabolic processes, then you need to drink more green tea. Studies have shown that the beneficial substances contained in green tea speed up metabolic processes and help burn an additional 70-80 calories. If you drink 5 cups of green tea a day and exercise for 15 minutes, you can significantly reduce body weight.
Contraindications to drinking green tea
Few people know (and this is practically not written or publicly reported) that green tea is the worst enemy for people with problems with the cardiovascular system. After all, according to scientists, green tea can disrupt the correct heart rhythm. Considering that the highest mortality rate in the world is from heart disease, it is very strange that this fact is hushed up.
In addition, a type of green tea - ginseng tea - is strongly contraindicated for cancer, and for women over 50 it should remain prohibited. After all, ginseng increases the amount of estrogen in the female body. And this, in turn, can stimulate the development of tumor diseases.
It is somehow not customary for consumers to talk about the fact that green tea promotes the formation of kidney stones. Moreover, this is not the result of some of the latest recent research. This fact was established back in the last century! Researchers from the University of New Jersey have found that drinking too much green tea can lead to kidney and liver disease. If you completely replace the daily dose of liquid with green tea (which, by the way, is now very fashionable in the fitness environment), then such an excess can lead to poisoning of the body with polyphenols, and this, in turn, can cause serious changes in the tissues of the liver and kidneys. And this despite the fact that it is thanks to polyphenols that green tea is considered such a healthy drink!
Patients with hypotension and persons For those prone to fainting, strong green tea is absolutely contraindicated. The same prohibition is also relevant for patients with gastritis, gastric and duodenal ulcers. In such patients, drinking green tea can cause heartburn, stomach pain, and intestinal colic. If you have an enlarged thyroid gland, strongly brewed green tea is also contraindicated.
Breastfeeding mothers should know that caffeine, which is contained in any tea drink, can cause insomnia in an infant. However, excessive intake of strong green tea can cause severe sleep disturbances in adults. Also, negative reactions from abuse of green tea drink can be: exhaustion of the body, increased heart rate and even trembling in the hands.
What to do? If green tea is fraught with so many dangers, maybe you should give it up altogether? Experts recommend purchasing herbal teas in pharmacies or, at least, by weight in specialized tea shops. This will minimize all the dangers from our usual tonic drink. Anyway all the main prohibitions on drinking green tea relate specifically to its strong, rich brew. Therefore, you should always remember that strongly brewed tea is more harmful to health due to its astringent properties than its weaker counterpart. The main secret of the healing effect of tea drinking is its moderate intake. The ideal dose of green tea is a couple of mugs a day.
Myths about green tea
The first thing that hurts the ear in this laudatory ode to green tea is some contradiction in the properties attributed to it: sometimes a tea drink made from green leaves is declared to be an invigorating agent, sometimes a calming one. What's the catch here? It turns out that there is a so-called golden rule of tea drinking. For that to drink tea correctly, you should remember three numbers: 2-5-6. It's minutes. If we drink tea 2 minutes after brewing it, we get an exciting effect; after 5 minutes – calming; after 6 minutes, all the essential oils from the tea have already evaporated, and we simply drink a drink with a weakened aroma.
You should also remember that tea can bring the greatest benefit to the body only in the first 15 minutes after it is brewed. And after 5 hours of infusion, additional boiling of the tea leaves or adding boiling water to it, the tea can turn into a real poison for the body.
In our latitudes, drinking tea closely coincides with the main meal and is considered a kind of logical continuation of the same tomorrow or lunch. Experts say that in this case, you can completely forget about the benefits of tea. Tea can have its beneficial effect only when we consume it as a separate meal, i.e. at least with a half-hour difference from the main meal.
In fact, many plants do have healing properties. This was well known to our great-great-greats. You can verify this by looking at any herbal reference book. But all this has nothing to do with what awaits us on store shelves. The herbal infusions and tea bags offered to us for sale are often empty, saturated with various kinds of flavorings. Such teas not only have no benefit, but can even be harmful to health.
One of the major tea suppliers in Russia, in an anonymous interview with a well-known TV channel, admits that selling high-quality pure tea in the post-Soviet space today does not seem to be profitable. The amount of cheap and low-quality tea on supermarket shelves negates all the efforts of suppliers to bring a quality product to consumers. It’s just that the latter cannot withstand any price competition with its cheap analogues. Therefore, those who try to import high-quality goods into the country sooner or later resort to sprinkling real pure tea with cheap dummy additives, thereby reducing the cost and reducing the selling price.
Due to the fact that there is very little quality real tea, experts advise buying it by weight and not in bags. By weight, you at least visually see what quality of tea you are getting, whether it is sprinkled with strange brown shavings or other suspicious elements. In bags, we definitely get a “pig in a poke.” After all, what is inside the thin whitish bag will remain a sealed secret for us. Of course, brewing tea in a bag is much more convenient than dealing with its loose counterpart. But the risk of receiving a low-quality product increases many times.
When choosing green tea should also be remembered that the cheapest green tea is small-leaf, and the highest quality is large-leaf. There are also powdered and slab varieties of green tea, but they are practically not imported to the post-Soviet space.
It is a huge misconception that an indicator of the quality of green tea is its rich aroma. The aroma of tea is given only by the essential oils that the manufacturer adds to it. What is sold in our stores does not even smell like essential oils, but is simply impregnated with artificial flavors.
Inside and outside
Green tea contains several times more vitamin C than lemon juice, vitamins P, B, K, PP, microelements fluorine, iodine, zinc. Fluoride compounds contained in green tea leaves protect teeth from caries, and gargling with green tea can stop the development of acute respiratory infections and flu.
But the most amazing thing that green tea retains all its beneficial properties not only when taken orally, but also when used externally. Many cosmetics companies take advantage of the antioxidant properties of green tea. Its extract is widely used in the creation of restorative, rejuvenating, moisturizing and sunscreen skin care lines. Natural masks based on green tea leaves can be prepared at home, depending on your skin type by adding milk, oatmeal, or sour cream.
A skin scrub based on brewed green tea with the addition of sea salt will help cleanse your skin.
Green tea scrub recipe from Ekaterina Titova:
Brew three large balls of jasmine tea, let the leaves fully expand. After 20 minutes, drain the water and mix the jasmine flower leaves with 2 teaspoons of sea salt (available at the pharmacy).
Apply the mixture onto your face with gentle movements and gently massage the skin for a minute, paying special attention to the T-zone. Then rinse off the scrub first with warm and then with cold water. The skin will become smooth and radiant.
- During the Chinese Tang dynasty, tea trade was declared a state monopoly, and large landowners were obliged to sell tea and receive bonds in return. They were allowed to buy other goods. These tea bonds soon became the first paper money (1024);
- It is to tea that we owe the fact that Heinrich Schliemann had the funds to excavate the legendary Troy. He earned part of his million-dollar fortune by selling tea. In his memoirs, Schliemann writes: “When cotton became too expensive, I gave it up and began selling tea... My first shipment to Mr. Henry Schroeder in London consisted of 30 boxes of tea, after I managed to sell it profitably, I ordered 1000, then 4000 and 6,000 boxes, bought the entire tea warehouse of Mr. Günzburg in St. Petersburg on the cheap and in the first 6 months earned 140,000 marks on tea, while receiving another 6% of the capital”;
- the famous “Boston Tea Party,” when boxes of tea sent from London, unfairly taxed by the British, flew overboard - this “drop of tea” on the night of December 15-16, 1773 overflowed the patience of the Americans. The prospect of being left without their favorite tea prompted them to take decisive action - separation from England began. It’s a historical curiosity, but, in fact, the United States was, to some extent, born of tea;
- The British have their own tea drinking traditions. For example, pour milk into a cup first, and then tea. Or place a spoon across the cup, signaling that enough tea has been drunk - please do not add more. Those who were not familiar with local etiquette could pay severely. One day, a certain Prince de'Broglier was forced to drink 12 cups of tea before someone figured out how to manipulate a spoon. They say that one foreigner, in desperation, thought of hiding the cup in his pocket so as not to drink any more tea;
- Cardinal Mazarin introduced tea to the royal court of France, who took it as a cure for gout. Even by the end of the 17th century, knowledge about tea remained very scarce. It got to the point of being ridiculous: it was recommended to smoke tea like tobacco, lightly flavored with brandy, and it was recommended to whiten teeth with ashes. The French were drawn to fashionable exotics, and tea took pride of place here. Even if he didn’t like him, none of the high-society fashionistas dared to refuse him;
- Until the middle of the 19th century, Moscow consumed up to 60% of the tea imported into Russia. There was an expression “Muscovites-tea-drinkers”, although Little Russians and Cossacks disparagingly said: “Muscovites-water-drinkers”. The fact is that in these regions, even in the 19th century, they knew about tea only by hearsay and identified it simply with drinking water;
- According to the results of auctions of elite teas held in Hong Kong and Guangzhou in 2005, the most expensive tea was the Chinese “Da Hong Pao” (“Big Red Robe”). The price per kilogram of this tea reached $685,000.
Even in Ancient China, they knew about the miraculous benefits of green tea and often used it for medical reasons. This type of tea was the first tool, for example, against headaches and depression. Green tea has an important place in Chinese history.
It is made from the leaves of the Camellia Sinensis plant. Unlike black, green contains a minimal amount of caffeine, which in overdose leads to insomnia, nausea and frequent urination. Green tea is beneficial because it contains a significant amount of vitamins C and P. Vitamin C is an antioxidant and is necessary for the normal functioning of bone tissue. Vitamin P strengthens the walls of capillaries, reduces their fragility and prevents destruction, especially in the bodies of older people.
To prevent diseases, it is enough to drink 2-3 cups of green tea daily. The usual daily intake is 250-300 mg.
Green tea supplements, sold in pharmacies and specialty stores, also have beneficial therapeutic effects.
If you prefer to drink green tea with milk, then you are depriving your body of incredible benefits. Milk proteins combine with polyphenol and suppress its healing properties.
Green tea contains beneficial catechins. These are potential antioxidants - 100 times more powerful than vitamin C.
It has been scientifically proven that catechin protects cellular DNA from changes and prevents the development of cancer.
Black tea also contains catechin, but in much smaller quantities.
Benefits of green tea: reasons to drink it every day
1/ Provides the body with antioxidants.
Experts believe that antioxidants slow down the aging process of the body and protect against heart disease, prevent stroke and the proliferation of cancer cells. Green tea is an excellent source of antioxidants and catechins in particular.
In fact, some fruits, such as pomegranate, for example, contain as many or even more antioxidants. But if you compare prices and consumer tastes, green tea is definitely the best choice.
2/ Burns fat.
By drinking green tea, we get two benefits in one.
- Firstly, it promotes natural fat burning.
- Secondly, it helps produce energy.
In Taiwan, scientists conducted a study in which more than 10,000 people drank green tea for 10 years. Based on the results, it became clear that green tea and its variety, oolong, help burn fat. And the longer you drink tea, the more significant the result will be.
Green tea improves endurance during exercise thanks to catechin, which burns fat and limits the immediate absorption of carbohydrates, and instead the body uses stored fat for energy.
3/ Extends life.
One of the largest tests (more than 40,000 participants) using green tea was conducted in Japan. Its results were collected and processed over 11 years.
Researchers found that people who drank about 5 cups of green tea per day lived an average of 16% longer than participants who drank less than one cup.
4/ Protects against cancer.
The unusual anti-cancer properties of green tea are not limited to just the effects of antioxidants. It is known that the drink limits the nutrition of cancer cells, and gradually they may die altogether. This effect does not apply to healthy cells.
According to scientific theory, green tea blocks the production of harmful enzymes that act as catalysts for the development of cancer cells. Brain tumors and leukemia, lung and stomach cancer, diseases of the colon and esophagus, bladder and breast cancer, ovarian and prostate cancer - all studies on the effect of green tea on the development of these diseases show positive results.
5/ Relieves stress and stimulates brain function.
All types of tea contain a certain ingredient - theanine, known for its calming effect and stimulation of alpha brain waves.
In 2007, it became known that 4 cups of tea a day increase the performance of the brain and the body as a whole. Therefore, people who regularly drink green tea are less susceptible to stress and are 44% less likely to experience symptoms of depression.
The list of benefits from theanine is getting longer every day. It has a known healing effect on both the psyche and human physiology. Two studies in 2007 made breakthroughs in proving that green tea repairs damaged brain cells and is a successful alternative treatment for multiple sclerosis.
6/ Rejuvenates and protects the heart.
Drinking this type of tea helps patients recover from a heart attack. Doctors suggest that one of the active ingredients, epigallocatechin gallate (EGCG), speeds up the recovery process. It also reduces the risk of heart failure, although experts still cannot explain the mechanism of action.
7/ Strengthens blood vessels.
With age, arteries tend to harden and their elasticity decreases. The process intensifies with the accumulation of lime deposits on their walls. When the inner layer of the artery becomes denser, the distance between the vessels narrows and blood circulation worsens. It is a cause of heart failure and stroke.
A 2009 study indicates that green tea prevents atherosclerosis, the hardening and clogging of blood vessels. The dose recommended for preventive purposes is 3-4 cups of tea per day. In this case, the risk of atherosclerosis is reduced by 26-46%.
This drink helps in maintaining the cleanliness of the arterial ducts by reducing cholesterol levels and the number of platelets in the blood.
8/ Reduces blood pressure.
Scientists have proven that this tea lowers blood pressure. One study conducted in 2004 found that people who regularly consumed green tea had 65% fewer signs of hypertension. The recommended dose is 2 glasses per day.
9/ Protects against the onset of diabetes.
The ingredient epigallocatechin gallate (EGCG) regulates blood sugar levels, increases insulin activity and glucose metabolism. In 2007, it became known that tea increases insulin activity by more than 15 times, but adding milk reduces the activity by 90%.
It is important to know that 6 cups of tea a day for 8 weeks reduces blood sugar levels from 15 to 20%. This effect is enhanced by following the Japanese diet.
10/ Heals from diseases.
You will be surprised to know that the anti-inflammatory properties of green tea make it an ideal alternative for ailments.
For example, rheumatoid arthritis is a common disease that occurs in three out of 100 women (the disease is 3 times less common in men). There are currently no treatment options for this disease. But among effective remedies for reducing pain and overcoming rheumatoid inflammation, green tea takes first place.
If you have skin problems, such as acne, green tea cream will help. It also helps with dry skin, itching and allergic reactions. This type of tea also reduces inflammation of the inner lining of the intestines.
11/ Reduces lung damage from smoking.
Green tea reduces the risk of lung cancer and limits cell damage from cigarette smoke. It doesn't matter whether it's active or passive smoking. Even when toxins enter from the air, poisoning with harmful substances does not occur.
With regular consumption of tea, the risk of disease is reduced to 25%.
12/ Protects the liver from alcohol.
Two studies over the past five years show that green tea protects the liver from damage caused by alcohol abuse or toxic chemicals.
The results of the experiments were so categorical that scientists plan to create a drug based on green tea to treat liver diseases.
13/ Protects tooth enamel from the development of caries
Protects tooth enamel from the development of caries and helps treat bad breath. Unlike carbonated drinks (which always contain sugar), green tea does not contain sweetness.
In addition, it fights viruses in the oral cavity and prevents the appearance of unpleasant odor.
14/ Provides bone density.
Drinking just two or more cups of green tea a day helps maintain bone density and reduces the risk of osteoporosis. The longer you drink tea, the stronger the integrity of bone tissue.
15/ Strengthens the immune system and repels cold and flu viruses.
Tea contains antigens that are also present in some beneficial bacteria. With the help of such antibodies, the body builds an immune defense and neutralizes harmful bacteria and viruses. 4-5 cups of green tea per day is enough.
16/ Moisturizes body cells.
UK specialists have found that the benefits of green tea are even greater than those of pure water. They refute the claim that tea dehydrates the human body.
Experiments conducted by scientists show that this amazing tea has a moisturizing effect.
