Is green tea healthy? And if yes, to whom and to what extent?

This drink has been used since ancient times to relieve depression and headaches, and modern people also note its ability to burn fat, lower blood pressure and the level of bad LDL cholesterol in the blood. Today, the Forest Fairy blog will take a closer look at the beneficial properties of green tea for the human body, the correct ways to brew it, and individual cases in which its use can be harmful to your health.

Before you find out what the real benefits of green tea are and what contraindications there are for it, check out these interesting facts:

The benefits and harms of green tea for the body. What does this drink contain?

Green tea is a rich source of potassium, vitamin C and some B vitamins, which dissolve well in water and are absorbed by our body. Another important component of green tea is the antioxidant flavonoids, including proanthocyanidins who are actively fighting age-related diseases, diseases of the circulatory and digestive systems.

More about the beneficial properties of green tea will tell you this table and the information below.

Figure Source: US National Nutrient Database for standard reference. The numbers characterize regular, water-brewed green tea and may vary slightly depending on the variety and growing conditions of the product.

Antioxidants in green tea and their effect on the body

Green tea is distinguished by a rather high content of plant antioxidants - flavonoids and catechins, the most active of which is epigallocatechin gallate or EGCG. This is a very powerful antioxidant, which, according to many scientists, can slow down the growth of cancer cells and the aging of the body. Together with other antioxidants found in green tea, including proanthocyanidins, it also helps:

• Facilitate digestion and speed up the metabolism in the body;
• Lower blood pressure and LDL cholesterol levels in the blood;
• Freshen breath and eliminate bacteria that cause cavities and other oral diseases.

Attention: To date, not enough clinical studies have been conducted to allow green tea or its extracts to be used with complete confidence in the treatment of cancer and cardiovascular disease. For example, studies that confirmed the ability of green tea to reduce the risk of developing liver cancer were carried out only among the Chinese and Japanese population.

Still, current data on how green tea affects different people with their individual characteristics remains rather limited. Before using it for medicinal purposes, be sure to consult your doctor and follow the recommended dose.

Caffeine in green tea - good or bad?

A cup of green tea contains an average of about 30 mg of caffeine. For comparison, black tea contains an average of 55 mg, Red Bull 75 mg, and regular coffee 90 mg of caffeine per 250 mg cup. How does this affect a person?

Caffeine is known to have a stimulating effect on the brain, giving a sense of strength and uplifting mood. However, the antioxidant EGCG and L-theanine in green tea neutralize the effects of caffeine to some extent and make this drink much safer. L-theanine is one of the few amino acids that has been shown to reduce anxiety, lower blood pressure, relax, improve learning, and boost immunity. Therefore, a cup of green tea can always be drunk in the evening without fear of insomnia.

Note: in the usual way of brewing tea, we get quite a small amount of L-theanine. To completely release it into a drink, the first brew of green tea is drained, after which the leaves are boiled at a high temperature of water up to 127 ° C.

Here you also need to pay attention to the fact that caffeine contributes to dehydration and is considered a good diuretic. There are studies that have shown that the catechins in green tea prevent the caffeine from dehydrating the body. However, many people have noticed that after drinking tea, they begin to run to the toilet more often. Therefore, just listen to your body and do not abuse this drink if it has the same effect on you.

Finally, we note that many scientists consider the caffeine in green tea to be safe and have even given it GRAS (certainly safe foods and ingredients) status. In any case, today green tea remains the safest and most beneficial of all caffeinated beverages.

Green tea: raises or lowers blood pressure?

Due to the caffeine content, the question often arises: does green tea increase or decrease blood pressure? We have already mentioned above that L-theanine neutralizes the effects of caffeine, but the amount of this amino acid in the drink directly depends on the method of brewing it. It also contains catechins, which have a beneficial effect on the heart and blood vessels. What is the effect of green tea in general?

All the experiments carried out gave one result: green tea lowers blood pressure. The cumulative benefits of green tea for hypertensive patients are obvious! A general meta-analysis of studies showed that the systematic consumption of green tea for 3-6 months contributes to a decrease in systolic and diastolic pressure by about 3 mm Hg. Art.

Does Green Tea Really Help You Lose Weight?

No global studies confirming the benefits of green tea for weight loss have yet been conducted. However, there are a number of facts that testify in favor of this assertion:

1. Green tea has the ability to speed up metabolic processes, which makes the human body burn calories faster without any exercise.
2. Green tea is not able to suppress appetite, but it allows you to temporarily increase the endurance of the body. Polyphenols in its composition accelerate thermogenesis (the production of heat by our body to keep all its systems working) and promote the use of calories as energy.
3. The catechins in green tea help regulate blood sugar levels and prevent obesity by preventing glucose from being stored in fat cells.
4. Caffeine, which we talked about above, interacts well with polyphenols and also increases the rate of fat burning.

Slowly but surely, green tea helps to lose weight by causing the body to lose fat while maintaining muscle mass.

Possible harm of green tea to the human body

Moderate regular consumption of green tea is considered generally safe, but there are still some limitations and contraindications for it.

So, green tea can be toxic to the liver if the recommended consumption rates are exceeded (10-29 mg of tea per 1 kg of body weight per day). In addition, too high doses of green tea, which contains a lot of antioxidants, can begin to act as a pro-oxidant and damage healthy cells in the body.

Heartburn and indigestion are common consequences of overconsumption and/or improper brewing of green tea. This harm can be prevented by brewing the drink with water well below boiling point. Ideal - in the range of 71-82 degrees Celsius.

Also, green tea may be contraindicated in the following cases:

• Iron-deficiency anemia. Consuming green tea can create an iron deficiency in your body, which greatly affects people who are anemic. This harmful property of tea can be neutralized by adding lemon to it.
• Allergy. Extremely rare, but still, some people have an allergic reaction to Chinese green tea: swelling of the throat, difficulty breathing, swelling of the lips, tongue and / or face, fever.
• Sensitivity to caffeine. With excessive consumption or hypersensitivity to caffeine, green tea can cause a person to be anxious, have a palpitation of the heart, irritability, sleep problems, etc.
• Pregnancy. Green tea is not recommended for pregnant women to consume in large quantities, especially in the early stages. Caffeine, tannins and catechins in its composition can lead to birth defects.
• Taking medication. If you are taking any medications, be sure to check with your doctor about your green tea intake.

Of course, the benefits of green tea depend on the amount you consume. Experts recommend drinking from 10 to 29 mg of green tea per 1 kg of body weight per day. Thus, for a person weighing 60 kg, the recommended dose is in the range of 600-1740 mg (from 2 to 6 cups), and for a person weighing 85 kg - in the range of 850-2465 mg (3-9 cups). However, given the existing contraindications and research data, it is better not to bring the amount of tea drunk per day to the upper limit. According to several studies, a dose of 6 cups of green tea is too much for normal daily consumption. Side effects of this intake can include frequent urination (and, as a result, dehydration), diarrhea, vomiting, dizziness, headaches, and loss of appetite.

Be healthy!

In addition, it is a well-known antioxidant, which, according to research, is an elixir of youth and a means of preventing oncology. However, everything is good in moderation. To answer the question of whether green tea is harmful, you should figure out how much this drink should be consumed and whether it poses a danger to human health.

Is green tea dangerous?

Green tea can also be hazardous to health. If you drink a lot of tea, and there is no difference - black or green, then a shock amount of flavanoids enters the body - biologically active compounds, due to which the digestive organs are cleansed. Large daily portions of this drink can provoke malfunctions in the digestive tract and overload the liver and kidneys. In addition, do not forget that green tea has more caffeine than coffee, so if you drink it in large quantities, you can just not close your eyes.

It is believed that if you drink hot tea, there is a risk of developing throat cancer, not to mention the fact that boiling water burns the esophagus, which can harm the entire digestive tract. It is best to enjoy freshly brewed tea as it has the most benefits and is not bitter. Some prefer to drink chilled or very cold tea, which quenches thirst and tones well.

The harm of green tea for people who have serious joint problems cannot be denied either. The fact is that it contains purine, which helps to eliminate toxins. However, if you drink a lot of tea drink, this substance can accumulate and be converted into salts, which causes significant harm to patients suffering from rheumatism, arthritis and similar serious illnesses. No wonder, as soon as a person stops drinking coffee, green or black tea, he immediately feels better.

Who Shouldn't Drink Green Tea

The lethal dose of tea is about 130 cups a day, but you can hardly drink this amount of this drink. However, there is a group of people who are strongly discouraged by doctors from drinking green tea, as it is too harmful for them. Conditions and diseases in which it is undesirable to use this drink are listed below:

1. Pregnancy and lactation. Due to the fact that the green tea drink is rich in caffeine, it can affect the fetus through the circulatory system, and those mothers who love strong tea are at risk of giving birth to a small child with muscle hypertonicity. During lactation, you need to be especially alert and not lean on green tea, because, in addition to excessive nervous excitability, the baby may have problems sleeping. As for pregnant women, if you drink this drink on an empty stomach, it can cause nausea and other symptoms of toxicosis.
2. Gastric or duodenal ulcer, erosion, gastritis. Despite the fact that green tea cleanses the digestive system of toxins and toxins, its component theophylline can prevent erosions and ulcers from healing, as it contributes to an increase in acidity in the stomach. In addition, tea is also harmful to the intestines, because caffeine has a laxative effect, and with such serious ailments it is contraindicated. It often happens that you feel sick from green tea - this happens because under its action the muscles of the esophagus relax. Gagging may occur - a common occurrence with increased acidity or when drinking this drink on an empty stomach.
3. Insomnia, depression, neuroses. In all these conditions, the intake of tea should be minimized, as it acts as a stimulant. In addition, an excess of caffeine can cause frequent headaches. This drink is not so harmful as to be completely abandoned, but in such cases it is recommended to drink it only in the morning. But drinking tea with milk at night with such diseases will be very helpful.
4. Hypertension, diabetes mellitus. If there are problems with the heart and blood vessels, as well as frequent pressure surges, drinks such as tea should be consumed with caution, as they contain caffeine. There are many cases that hypertensive patients feel sick from an excess of caffeine after strong tea, so if you drink this drink with such a disease, then the tea leaves should be weak. Tea affects blood sugar levels, so diabetics should also refrain from drinking this drink.

The fact that tea harms the reproductive system has not been proven. However, its constant use gives overexcitation, and then lethargy and, as a result, a decrease in sexual activity.

• do not buy low quality tea. It is not recommended to buy green tea in bags - as a rule, tea dust is packaged there. It is better to give preference to proven manufacturers of loose leaf tea;
• do not drink tea along with alcoholic beverages, as this combination puts an additional burden on the liver and kidneys;
• drink tea with food, but do not get carried away in the morning on an empty stomach.

When there is a need to cleanse the body of toxins, a green tea drink will come in handy. However, it will not be harmful if you drink no more than one and a half liters of this drink per day. The maximum duration of the course is one week, and the result will be more noticeable if you additionally eat a lot of vegetables and fruits.

Often drinking tea for the purpose of recovery is not worth it, if you want to repeat the course, then this can be done no earlier than in a month. But this does not mean that you need to completely abandon your favorite health-improving drink - it is recommended to drink green tea daily in the amount of two cups, but no more.

Is it worth giving up your favorite drink for fear of harming your health? A couple of cups of aromatic tea a day will not do any harm. In addition, people who lead a sedentary lifestyle and spend a lot of time at the computer, doctors recommend regularly drinking this anti-carcinogenic drink.

What harm can green tea cause if you drink it more than 3 cups a day

Good afternoon, dear readers! Everyone knows about the healing properties of green tea. And many are sure that this delicious drink is completely harmless, because it has so many health benefits. But there are hidden dangers in this health drink, which will be discussed: the harm of green tea.

Based on studies conducted by the UK Tea Council, it was found that a healthy drink, if consumed in moderation, can cause side effects to human health.

What harm can green tea do?

The harm of green tea is expressed in its side effect, which experts associate with the content of caffeine and tannins (tannin and catechin).

In the meantime, tea has enormous health benefits. Read, Green tea prolongs life.

Tannins. In their effect, the tannins contained in the tea leaf are similar to vitamin P, they strengthen the walls of blood vessels and capillaries. The tea itself is given flavor and astringency. But their high concentration in tea irritates the walls of the stomach, they slow down the absorption and assimilation of certain trace elements and can disrupt the functioning of the liver and kidneys.

Caffeine, a purine alkaloid, is a powerful stimulant of the human nervous system, which has a number of positive effects on health. But an overdose of the alkaloid causes disruption of the heart, stomach, intestines and other body systems.

With an overabundance of even the most useful food, the body is in danger, because all products contain chemical elements and biologically active substances that the body cannot absorb indefinitely. Their excessive exposure takes the body out of the comfort zone, causing failures and disruptions in the functioning of organs and systems.

Side effects or why to comply with the norm

Scientists have established a number of side effects that occur more often with an overdose of green tea, which is harmful for both women and men.

Changes the acidity of the stomach

Green tea changes the acidity of gastric juice, increasing it above normal, which causes irritation of the walls of the stomach and can provoke heartburn. Scientists came to this conclusion, studies have shown that tea stimulates the production of stomach acid.

To neutralize its effect on the walls of the stomach, you can add sugar to tea, which, again, is not welcomed by everyone. It is better to drink a drink after a meal or between meals, when the stomach has not yet been freed from food.

People with high stomach acid and peptic ulcer need to be more careful in drinking this drink.

Reduces iron absorption

Since tea is drunk only after a meal, it interacts with substances contained in food. It has been established that caffeine, or rather theine (this is the same caffeine found in tea, differs from caffeine in that it is absorbed only in the intestines), reduces the absorption of iron by 25%. This applies more to the non-heme iron found in eggs, dairy products, and plant-based foods.

But this harmful effect on the body, fortunately, can be neutralized if you add fresh lemon juice to a cup of tea or eat vegetables and fruits saturated with vitamin C first (greens from the garden with darkly colored green leaves, tomatoes, broccoli, lemon, currants) .

For women, it is important to observe moderation in tea drinking. Often without that, they suffer from anemia and iron deficiency, and large concentrations of tea exacerbate this situation. During pregnancy and breastfeeding, the concentration of caffeine can affect the development of the fetus and the health of the child.

Contributes to the development of chronic headaches

If a person constantly consumes drinks containing caffeine, the body gradually gets used to it. And with a lack of this “doping”, he responds with a long headache. This is a kind of caffeine addiction, causing a kind of withdrawal when it is not enough.

Additional intake of drinks solves this problem in minutes, but is it worth accustoming your body to such an addiction? If headaches appear due to a lack of caffeine doping, it is better to completely abandon such drinks. After all, these symptoms will gradually increase.

Sometimes people have chronic headaches that turn into migraines. Studying such cases, scientists have found a connection of such pain with the use of drinks (in large doses) containing caffeine.

Causes anxiety and nervousness, interferes with restful sleep

All these symptoms are more pronounced in sensitive people with overdose. It's all about the substance xanthine, which is a purine base and a precursor of uric acid. Its derivative is caffeine.

Its side effect on the human body is the ability to block sleep hormones in the brain, and it also activates the production of adrenaline.

Increases heart rate and blood pressure

Sometimes there is a rapid contraction of the muscles of the heart (palpitations) or abnormal contraction, with rhythm disturbance. As a rule, such failures and violations pass quickly. And if such cases take place, then it is better to talk with your doctor, undergo an examination and identify the true cause of the deviations.

If a person has an increased sensitivity to caffeine and its derivatives, then it is better to refuse drinks containing it in their composition.

You should not get carried away with drinks and people with high blood pressure, the fact of the effect of caffeine on the increase in pressure is well known.

Causes diarrhea

This feature directly depends on the individual sensitivity of the body. In the lining of the mucous membrane of the digestive organs, a huge number of neurons (nerve cells and endings) are concentrated. Therefore, the digestive organs are very sensitive to all chemicals that come with food.

And drinks containing caffeine are rich in organic acids (citric, succinic, malic, oxalic), which stimulate the production of bile. At some point, this plays a positive role.

But accumulations of bile, in turn, trigger mechanisms in response to the effects of biologically active substances that make you run to the toilet. For those on whom caffeinated drinks have a laxative effect, it is best to avoid them.

Promotes heartburn and vomiting

Medical experts acknowledge the fact that caffeinated drinks can cause heartburn. This is explained by the fact that when the mucous membrane is irritated by caffeine derivatives, the production of hydrochloric acid increases.

And since the active substances also have vasoconstrictive abilities, this to some extent disrupts the work of the sphincter, which does not work on time and passes hydrochloric acid into the esophagus.

Do not drink the drink hot, as it irritates the gastric mucosa more and do not work in an inclination after drinking a cup of tea.

An overdose of tea sometimes causes nausea, which turns into vomiting, which is rare. This is also associated with a change in the acidity of the stomach and the irritating effect of active substances on the vomiting center of the brain.

Possible dizziness, ringing in the ears

Caffeine derivatives have insidious properties. In small doses, they increase blood pressure, cause vasospasm, which can cause dizziness.

With an overdose, on the contrary. lower the pressure. And again, they cause weakness and dizziness. You may experience ringing in the ears, especially with high blood pressure.

Causes trembling of the limbs and lack of calcium in the body

Hand tremors or trembling of the limbs may appear due to the influence of the drink on the absorption of calcium. In addition, a lack of calcium affects the density of human bone tissue, which contributes to the development of osteoporosis, which is expressed by a decrease in bone strength and fragility, which increases the risk of fractures.

Harmful effect on diabetic patients

Caffeine derivatives affect people differently, especially those who suffer from diabetes should be especially careful. The thing is that if a person constantly takes drinks (more than 4 weeks) containing caffeine, they reduce blood sugar, which reduces the risk of developing the disease by almost 50% (as scientists say).

But the periodic intake of drinks and tea, on the contrary, increases blood sugar levels, and in sick people they reduce insulin sensitivity.

For men

And for men, too, there is a certain harm in large quantities of drinking tea. Brazilian scientists believe that the active substances in tea reduce the level of testosterone, the male hormone that regulates male strength and reduce the production of seminal fluid, which can affect the reproductive function of men.

How does it affect the liver and kidneys

Tea for the liver and kidneys is undesirable when these organs have any pathology. It all depends on the amount of consumption of the drink, if you drink it a lot, then the polyphenols contained in the leaves accumulate and their excess negatively affects the functioning of the internal organs.

How much tea can you drink a day

Studies by scientists in the UK say that the danger to health lies in 6 cups of tea.

• 3-4 cups will bring only health and benefits.
• 5 cups puts some strain on it, but is still safe.

According to experts, the consumption of green tea in large quantities leads to irreversible health consequences. But for this you need to drink about 420 cups of tea, given that the lethal dose of caffeine is 14 g, and a cup with a capacity of 240 ml of tea contains 25 mg of caffeine.

Three cups of tea contains up to 300 mg of polyphenols, which, with their antioxidant properties, protect the human body from diseases, support the functioning of internal organs, strengthen the immune system, and slow down aging.

Can I drink cold tea

Experts do not recommend drinking both too hot tea and cold tea. Hot tea can burn you, and frequent consumption of hot drinks causes a mutation in the epithelial cells lining the throat, leading to the formation of a malignant tumor.

Cold tea, after standing, quickly oxidizes, which leads to the destruction of the vitamins, minerals and active biological substances contained in it. There will be no particular harm from this, just thinking about the usefulness, you will drink a pacifier. But in cold tea, a favorable environment for the reproduction of bacteria is still created.

The biologically active substances contained in green tea, which bring benefits, can be potentially harmful to health if consumed in excessive amounts. The harm of green tea for the body lies only in this reason. If you follow the rule of the golden mean, then all problems will go aside.

The judicious use of tea turns the caffeine and tannin contained in it into friendly substances that bring only health.

Drink tea wisely and be healthy!

It's news to me that too much green tea can cause headaches. Thanks for the information.

Why is green tea harmful?

An experiment was carried out on laboratory mice. Rodents were given green tea extract for 6 weeks. As a result, their bone mass decreased markedly compared to the rodents from the control group.

Due to this, there is a decrease in the total body weight.

Researchers at the University of New Jersey have found that too much green tea can cause liver and kidney disease. Food supplements made on the basis of tea extract suffer from the same drawback - if they are consumed in moderation, symptoms of polyphenol poisoning are diagnosed.

Green tea is harmful and dangerous to health. Individuals should drink small amounts of green tea or avoid it altogether because green tea is not good for everyone. Green tea is especially harmful to pregnant women.

When green tea is bad: 19 side effects of green tea

As a rule, the side effects of green tea consumption are associated with caffeine, which, if ingested in large quantities, can lead to aggravation and various health problems.

1. Harm of green tea for stomach problems

Avoid drinking green tea on an empty stomach because it increases the acidity of the stomach, increasing the risk of nausea, stomach pain and constipation due to the tannins it contains.

The best time to drink green tea is between meals or after meals. People with acid reflux or peptic ulcers should not drink green tea in excessive amounts. According to a 1984 study, green tea is a strong stimulant of stomach acid. Scientists have found that adding milk and sugar to tea can reduce these stimulating properties of stomach acid.

It is correct to brew green tea at a temperature between 70 and 90 degrees Celsius, as in some cases the high temperature of green tea brewing can cause side effects. Using too hot water contributes to indigestion or heartburn.
