The benefits and harms of green tea, how to brew it?

Green tea is a perennial evergreen shrub growing up to 10m in height. The plant has beautiful, long, dark green leaves that have the shape of an oval. The leaves contain supporting sclereids in their pulp. In the axils of the leaves are fragrant flowers, collected 2-4 pieces or singly. The florets and bracts are arranged in a spiral. The fruit of green tea is a box, slightly flattened, consisting of three valves. Inside the fruit there are seeds of a rounded shape, dark brown.

From the end of summer to the last days of autumn, the flowering period of this plant lasts. The plant bears fruit from October to December. Green tea plantations are found in China, India, Japan, South America and Africa.

Green tea composition:

This fresh, strong drink contains a lot of chemicals, this is the reason for the beneficial effect of tea. More than half a thousand components are found in its leaves, including calcium, fluorine, which are so necessary for the body, as well as magnesium, phosphorus and many others. It contains several hundred complex compounds of organic origin and most of the known vitamins. The special usefulness of green tea is due to the presence of the following compounds in it:

Caffeine – this is the main alkaloid, its presence in tea gives strength and energy to our body, invigorates and activates the brain. However, regular tea does not contain caffeine, but its analogue, called theine. Theine action is somewhat milder than caffeine, while it also activates the energy of the human brain, improves mood, and with it performance and activity.

Mineralscontained in green tea contribute to the proper functioning of all our organs. Preventing the imbalance of minerals, it strengthens the immune system, contributes to the excellent condition of nails, hair and teeth.

Catechins Flavonoids are excellent antioxidants. Their impact is ten times greater than the effect of vitamins. Drink a cup of green tea throughout the day and your body will get all the polyphenols it needs. A similar effect has been found in catechins in other natural foods, such as carrots, spinach, strawberries, and broccoli. Being an effective antioxidant, this product suppresses free radicals in the body, reducing the risk of cancer. Tea increases natural immunity, destroys microbes, so it is recommended for dysentery.

[Video] 8 health benefits of green tea:

Этот напиток рекомендуется употреблять после перенесённых простудных заболеваний для более быстрого восстановления организма. Говорят, что он способен ускорить заживление ран и ожогов. Регулярное употребление настоя из чайных листьев снимает симптомы некоторых кожных заболеваний.

10 Scientifically Proven Health Benefits of Green Tea

The benefits of green tea are undeniable. It is rich in antioxidants that have a positive effect on brain function. These compounds help to get rid of excess weight, prevent the development of diseases of the cardiovascular system and even cancerous tumors. All of the listed properties of green tea are proven by science and confirmed by numerous studies. They are known all over the world, but the drink also has “hidden” benefits that little is known to the general public. It is about them that we will discuss in our article.

1 Fights cancer and chronic inflammation  

Green tea does more than just quench your thirst. It contains polyphenols that help immune cells fight cancer and stop the chronic inflammatory response.

The natural antioxidant from green tea is called epigallocatechin-3-gallate (EGCG). Once in the body, it neutralizes active radicals that can damage the normal structure of cells, lead to their degeneration and premature aging. Epigallocatechin is one of the most significant components of green tea. Scientists believe that it is he who gives the drink medicinal properties. ^[1]

In addition to biologically active substances, green tea contains minerals, although in small quantities. Among them: calcium, phosphorus, magnesium and potassium. To get the maximum benefit from the drink, preference should be given to quality varieties of tea leaves, as excess fluoride has been found in some inexpensive drinks. But even this fact is completely covered by the health benefits that tea provides.

2 Improves brain function

Caffeine is a brain stimulant. It is less in green tea than in coffee, so it improves cognitive functions, but does not cause negative nervous effects in the form of overexcitation, insomnia and anxiety.

Once in the body, caffeine blocks the inhibitory neurotransmitter adenosine. It increases the excitability of neurons, stimulates the production of dopamine and norepinephrine. Researchers claim that caffeine improves mood, speeds up reactions, improves attention and memory.

Another stimulant of the brain is the amino acid L-theanine, which easily overcomes the BBB – the barrier between cerebrospinal fluid and blood. It activates GABA (an inhibitory neurotransmitter that has a calming effect), stimulates the production of dopamine and alpha waves in the brain. Caffeine and L-theanine have been shown to mutually reinforce each other’s effects. ^[2]

3 Acts as a fat burner

Most weight loss supplements contain green tea extract. This is quite reasonable, since it is able to speed up metabolic processes.

The scientists followed 10 men who received green tea extract daily. By the end of the experiment, their metabolism accelerated by 4%. Another scientific study was conducted with the participation of 12 men. They had an increase in the rate of fat oxidation by 17%. The comparison was made with participants who received a placebo. However, there were also studies in which the relationship between the intake of green tea and the rate of metabolic processes could not be established.

The caffeine found in tea leaves also helps with weight loss. It increases physical performance and mobilizes fatty acids contained in adipose tissue. This allows the body to efficiently use them as an energy source. According to several studies, caffeine can increase physical performance by 12%. ^[3]

4 Protects against cancer

The formation of a cancerous tumor occurs against the background of cell division, over which the immune system has lost control. The process can be provoked by the oxidation of their membranes caused by attacks of free radicals. The antioxidants in green tea can prevent this.

Scientists have proven this fact with several studies at once:

• Women who often drink green tea are 20-30% less likely to experience breast cancer. ^[4]

• Men who drink this drink have a lower risk of developing prostate cancer.

• Both sexes who take green tea have a 42% lower risk of colorectal cancer. Conclusions were drawn on the basis of 29 studies at once. ^[5]

The maximum benefit can be obtained from a “clean” drink, without the addition of milk. There is evidence that it can reduce the activity of antioxidants.

5 Prolongs the youthfulness of the brain

Green tea is not only a charge of vivacity “here and now”, but also a great way to protect the brain from age-related changes. In particular, from Alzheimer’s disease and Parkinson’s disease.

Scientists have proven that the catechins present in the drink protect neurons from destruction and prevent the development of senile dementia. Although the studies were conducted in test tubes and in animals, the findings are impressive. ^{[6]  [7]}

6 Eliminates bad breath

The catechins present in the drink heal the oral cavity, preventing the growth of bacteria and reducing the risk of infection. Most of all in the human mouth bacteria of the genus Streptococcus mutans. It is this microbe that is responsible for plaque and caries.

Scientists suggest that catechins are able to suppress the growth of bacteria in the oral cavity, which has a positive effect on the health of teeth, gums, and tongue. And their ability to eliminate bad breath has been experimentally proven. ^{[8]  [9]}

7 Prevents the development of diabetes

The incidence of diabetes is growing rapidly. For example, in the United States, 1 out of 10 people suffer from this disease. It develops against the background of the inability of cells to produce or absorb insulin.

There is evidence that green tea can increase the susceptibility of cells to insulin and reduce its concentration in the blood. In a study involving Japanese residents, it was found that the consumption of this drink in large quantities reduces the likelihood of developing diabetes by 42%. ^[10]

The scientists also analyzed 7 other studies at once. In total, more than 286 thousand people were involved in them. All participants who drank the tea had an 18% lower risk of developing the disease.

8 Prevents diseases of the heart and blood vessels

The drink helps to reduce the level of low-density lipoproteins and total cholesterol in the blood. Therefore, it can be attributed to products that reduce the risk of stroke and heart attack.

Under the influence of the drink, an increase in the antioxidant protection of the blood is noted, which prevents the oxidation of “bad” cholesterol. It is no secret that this process entails severe cardiac diseases.

According to the scientific community, drinking tea reduces the likelihood of death from cardiovascular pathologies by 31%. ^[11]

9 Helps to lose weight

The process of getting rid of excess weight occurs due to the acceleration of metabolic processes. Green tea allows you to quickly remove fat deposits in the waist area, which is especially important. After all, it is around the abdominal organs that dangerous visceral fat accumulates.

Scientists conducted a study that lasted 3 months. It was attended by 240 obese people. In the group that received green tea, a decrease in the percentage of body fat was noticed. They lost weight, their waists became thinner. In the control group, no such changes were observed. However, further studies are required to confirm the findings.

10 Increases lifespan

Green tea acts as a means of preventing cancer and cardiovascular diseases. Therefore, it is not surprising that it increases life expectancy.

In Japan, a study was conducted in which 40 people over the age of 530 were followed.

Mortality was lower among those participants who consumed more than 5 cups of green tea per day. Namely:

• Death due to unexplained circumstances: 23% and 12% lower in women and men, respectively;

• Death associated with heart disease: lower by 31% in women and 22% in men;

• Death caused by stroke: 42% and 35% lower among women and men, respectively. ^[12]

Another experiment conducted with elderly Japanese found that the chances of a fatal outcome within 6 years (such a time the study lasted) decreased by 76% among green tea drinkers. In general, 14 people were involved in the experiment.

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.

A strong drink is definitely harmful for:

• With an unstable nervous system and with diseases of the cardiovascular tract. Of course, theine is bad for them. But tea is not rich in theine alone, it contains substances that actively influence these systems, which causes its harmful effects, for example, due to theobromine.

• When 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 an unpronounceable name “epigallocatechin gallate”. Again, we mention caffeine, which is contraindicated for pregnant women. Whether black tea prevents the breakdown of folic acid has not been proven for certain, but it does contain caffeine. Just a few cups of any tea a day can cause a baby to be born underweight, stimulate premature labor with possible fetal death.

• 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 a stomach ulcer. Rather, tea is contraindicated than really harmful. Strong tea, and green tea in particular, increases the acidity of the gastric juice, and this, in turn, interferes with the natural process of wound healing. As a result, the patient’s condition may worsen significantly.

• 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.

• Washing out beneficial trace elements. Tea removes metals from the body. Again because of theine.

• 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.

• 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. 

• 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.

• The absorption of iron. Caffeine interferes with the absorption of essential iron.

Harm of tea from improper use:

• It has already been said that old tea is harmful. When stored for a long time, it accumulates a lot of purines. Although at the time of brewing they are already formed, but over time, the processes of their formation increase and after half an hour tea is no longer worth drinking.

• The combined use of tea and alcohol causes an intense formation of aldehydes that harm the kidneys.

• Excessive consumption of the drink causes a state of intoxication, the head starts to hurt, nausea, dizziness rolls.

• Extremely hot drink should not be consumed 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.

• Brewing tea with boiling water makes it practically useless, since the most valuable substances are destroyed. But harmful elements are significantly added, the same purines, for example.

The use of green tea

Green tea is used for atherosclerosis, hypertension and various poisoning, even with alcohol. Green tea is a powerful antioxidant that helps fight obesity, weakness and fatigue. And also preparations from green tea are used for diarrhea, burns from sunlight, from caries and in various diets. Green tea is able to absorb about 90% of the isotope, preventing it from adversely affecting the human body. Due to its medicinal properties, green tea stops the growth of cancerous tumors.

Tooth decay is the most common problem for many teenagers and adults. Green tea quickly and effectively destroys bacteria in the mouth that prevent cavities from forming.

Green tea reduces cholesterol in the body, makes blood vessels more elastic, normalizes lipid metabolism, speeds up fat metabolism and prevents the body from aging quickly.

Green tea is an excellent diaphoretic. And if you mix it with lemon, the effect will be even better. In addition, green tea removes toxins from the body.

Green tea infusion for atherosclerosis, high blood pressure and high cholesterol. Take 3 grams of dry green tea and wash it with boiling water – this is necessary to reduce the caffeine content in it. Next, pour green tea with 100 ml of boiling water and leave for about 10 minutes. Take this tea in a glass at a time three times a day. But, given the fact that a person takes green tea, it is necessary to drink no more than 1,2 liters of liquid per day (this includes 3 glasses of tea itself).

Green tea infusion for dysentery. Take 25 grams of crushed raw materials of the plant and pour 500 ml of boiling water. Leave everything to brew for half an hour. Then put the composition on low heat for 1 hour. After that, you need to strain the finished infusion. We store such a drink only in the refrigerator. Take an infusion of 2 tablespoons 30 minutes before meals 4 times a day.

Tea for indigestion. Many people suffer from this disease. Green tea will help with it. This plant contains bactericidal substances that destroy pathogens in the intestines and stomach. To get rid of an upset stomach, it is enough to drink strong green tea for 2-3 days in the morning, at lunchtime and in the evening – and the ailment will pass.

Infusion for vitamin deficiency. We take 3 grams of crushed tea and pour 100 ml of boiling water, leave to brew for 10 minutes. After that, add 1 teaspoon of rosehip syrup to it. Every day after eating, we take such an infusion of 100 ml three times, only in a warm form.

How to brew green tea?

In order for green tea to be useful and give the effect that is expected of it, it must be brewed correctly.

There are three factors to take seriously:

• The main one is the water temperature and its quality.

• Portion of brewed tea.

• duration of the welding process.

The optimal combination of these three parameters will give an excellent drink. Let’s dwell on this in more detail.

1. How to determine the optimal portion of tea? Here it is necessary to take into account the size of the tea leaves, as well as the density of the tea leaves that you want to get. On average, one teaspoon is taken, based on a full glass of water.

2. What is the duration of the brewing process? This parameter depends on the size of the tea leaves, as well as the desired tonic effect – intense or slightly slow. Please note that theine, which causes such a desired tonic effect, dissolves in the first minute of the brewing process. Then there is a preferential saturation of tea leaves with tannins. Only after them our body assimilates theine itself. Therefore, when you expect an intense charge of vivacity from the tea ceremony, tea leaves should not be kept in tea leaves for more than one – one and a half minutes. On the contrary, if you want a not too intense surge of strength, but a long one, hold the tea leaves a little longer than indicated in the instructions. But keep in mind that the tea will turn out slightly bitter in this case. By experimenting with this indicator, you will find options that are acceptable for each specific case.

3. What water should be used for brewing? As with most drinks, spring water is the best option. Since not everyone lives near a spring, filtered water can be used. When there is not even one, then at least give the tap water time to stand a little. Purchased distilled water is not suitable for brewing. Also, do not boil water for tea again. In general, it is unacceptable for water to boil over, since it is by no means unacceptable to brew tea with fresh boiling water!

   The temperature of the brewing water is recommended in the region of 80-90 °C. 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!

4. What is the best container for brewing green tea? The best cookware is the one that holds the heat for a long time. Clay or porcelain teapots work well. Japanese tea connoisseurs use a teapot made of enameled cast iron, while Arabs prefer silverware. Dishes should not have foreign odors. To do this, pre-rinsing the dishes with boiling water will help a lot. It is also necessary that the cold kettle does not collect the heat of the water into itself, which was intended for brewing.

   When, after several brewing procedures, a yellowish coating appears on the inner surface of the kettle, do not rush to remove it. Such a film is a kind of protection against adverse external factors. Maybe this will alert guests who are not familiar with such subtleties of the tea ceremony, but I think you will find a way to explain the situation to them.

5. Direct brewing procedure. The kettle used for this purpose must first be heated over an open fire. Only then pour tea. The spoon must be dry and clean. The teapot is wrapped in a soft cloth. Gourmets of tea ceremonies use special beautiful things for this. The kettle is kept warm for a couple of minutes. The tea leaves are poured into a third of the container with hot water. Withstand another 2-3 minutes, after which the kettle is topped up to the eyeballs.

   Cups, preferably also made of clay or porcelain, intended for the tea ceremony, are rinsed with hot water before use. After all, hot tea poured into a cold cup cools quickly. The total duration of the brewing procedure is on average 3-4 minutes. The drink is poured into cups in small, equal volumes, so the same taste of tea is obtained for all guests.

6. Sometimes tea is prepared in the cup itself. (there are also such lovers) impose no more than one tsp. tea leaves. Such a drink is infused for about 2 minutes. The appearance of a yellow-brownish foam on the surface of the kettle means the correct cooking mode. It is not required to remove the foam, it is simply stirred with a spoon in a cup. Also, do not forget to warm the cup itself, in which the tea is brewed.

7. How many tea leaves are allowed and with what to drink tea? It is generally accepted that sugar is the enemy of green tea. It is better to use honey for dessert, and in its absence – dried fruits. Secondary high-quality tea is brewed up to seven times. However, it is better not to do this more than twice. We take a tiny mini-teapot, brew it once, and then repeat it again. Secondary brewing time is increased. The initial brew has the most tart aroma. Next, the actual taste of tea begins to unfold.

Can you always drink green tea? Many people use this healing drink, thinking that it quenches thirst well. For example, in Central Asia they drink it hot when working in the field, but this is a big mistake. Tea leaf brew is a strong diuretic, and drinking it in the hot season, a person thereby dehydrates his body. In addition, excessive consumption of tea leaves can lead to a deterioration in the state of the nervous system.

caffeine in green tea

Small doses of caffeine with moderate consumption of tea leaves from green leaves tone up, help relieve fatigue, increase physical and mental activity of a person. However, with all the beneficial effects of this noble drink on the body, one should not forget about its harm. It is because of caffeine that the abuse of green tea is not recommended for people suffering from cardiovascular diseases. This can lead to various complications.

Green tea with milk

This healing drink, mixed with milk, perfectly cleanses the kidneys, strengthens and tones the body. This “cocktail” is also very fond of Chinese centenarians. Milk neutralizes the effect of caffeine and other alkaloids, and therefore you can drink such a drink without fear for your health. Although this is a high-calorie product, the extra calories in it are compensated by calcium. An interesting study was conducted in which several women drank a glass of milk daily. Oddly enough, in the end, in addition to all the advantages of such a diet, in the form of strengthening nails, teeth and bones, weight loss was added to the subjects. According to the organizers of the experiment, this phenomenon is associated with calcium deficiency. Subsequently, scientists have developed a special diet based on green tea with milk, and its effectiveness has already been proven empirically. The cleansing processes in the body caused by drinking tea, in combination with a milk diet rich in trace elements, promotes weight loss without any harm associated with emaciation of the body.

What is the essence of such a diet? Two methods can be noted – soft and radical. When you’re aiming for an accelerated result and don’t experience stomach problems, drastic measures are applied. You should eat only a few fruits per day, giving up all other foods. We drink green tea with milk. Sugar, if the need for it is irresistible, change to a spoonful of honey. In addition to tea with the addition of milk, it is necessary to drink from one and a half liters of plain water. If this is all very difficult for you, then you are still indecisive in your desire to lose weight.

But let’s say your goal is just to get rid of toxins. Then a fasting day is what you need. Such a measure, of course, is much softer – just one day can be tolerated. But you still have to forget about ordinary food on such a day in order to let tea complete its effect.

Consider the ways of drinking a miraculous drink. There are also only two of them, and here are some.

Method one: Gourmets assure that the highest efficiency of the tea-milk diet will be achieved if the tea leaves are prepared directly on milk. That is, water is not used at all. Dry tea is poured with heated milk. In this case, plain water is drunk only separately from the drink.

Method two: This option is considered simpler, but not as useful. Boiling water and milk are mixed in equal parts by volume, and tea leaves are poured into such a mixture. Such tea is greener in color, but its taste is not so milky.

We also note that the use of green tea with milk is possible both hot and cold. It doesn’t make it any less useful. Green tea is very popular among athletes. Counting on the miraculous properties of tea, it is necessary to use it not only after training, but also before it. The range of beneficial effects of tea is huge. Connoisseurs of bodybuilding, fitness and just people of an active lifestyle include it in their diet. But low blood pressure is a significant reason to refrain from green tea. After all, one of its most important functions is precisely the fight against hypertension.

Green tea for weight loss

The medical community has not yet made a definitive decision whether green tea affects weight loss, although many people believe in the effectiveness of weight loss with this product. And this way of losing weight has recently become fashionable. It is believed that this infusion enhances metabolic processes in the body and accelerates the removal of fat, it is a powerful antioxidant and helps strengthen blood vessels, increasing their elasticity.

If you feel a slight hunger, then instead of a snack, it is better to drink a cup of infusion from tea leaves without sugar. With its regular use, you can lose 2-3 kg, and in combination with a diet, stunning results are achieved. Let’s remember the main tea gourmets – the Chinese and Japanese. Finding a fat man among them is very difficult. What is the ability of tea to get rid of excess weight? It turned out that among the beneficial qualities of green tea, it is precisely those that can cause weight loss that prevail. The drink perfectly cleanses the body, improves the functioning of the stomach and intestines, removing toxins, and increases metabolism. The positive effect of tea on accelerating the breakdown of fats has been proven. This drink allows you to forget about hunger.

Consider further how to more effectively use the beneficial qualities of green tea for people who want to get rid of excess weight:

1. Half an hour before a meal, just drink some tea (however, we note that drinking green tea before a meal is bad for the stomach. If you decide to drink it before a meal, then only 15 minutes before a meal). This is a great way to lose weight. For a single dose, a teaspoon is brewed into 300 g of water, infused for about two minutes and drunk without sugar. Such a technique will somewhat reduce the feeling of hunger, but at the same time it will speed up the processes responsible for the digestion of food, fat burning. It can be recommended to add plants to regular tea, which also contribute to weight loss. Among them, for example, hibiscus, which is distinguished by its mild laxative, as well as diuretic effects. Hawthorn fruits are also suitable, absorbing fats, lowering cholesterol. Another addition is finely ground cinnamon. With it, tea acquires an exquisite, pleasant taste, and metabolism will increase by an order of magnitude. Finally, even a brutal appetite suppresses a spoonful of flax seed, eaten with a cup of green tea.

2. Add green tea to your dinner table. There is one recipe that will probably seem original and even somewhat strange to you. Try grinding tea into a fine powder with a coffee grinder. Eat a spoonful of this powder during any of your meals. You can drink it with water. You can not even eat the powder in its pure form, but, say, sprinkle cold snacks on it, for example, salads, cereals, Russian salad. You should not only add it to various soups or cocktails containing a lot of liquid. In such dishes, the powder will simply dissolve and its effect will be significantly lower or simply weakened. This recipe has come down to us from China. And in this country people know how to keep a figure.

3. If you are already on a diet, then tea is perfect to improve the effect. In general, the best nutritionists recommend drinking green tea as often as possible when losing weight. Eating fruit and vegetable dishes helps to quickly get rid of excess weight. At the same time, reduce the amount of sweets and flour products in your diet. Replace fried meat with fats with boiled. Try to reduce the amount of salt and especially sugar in your food. But all kinds of cereals – buckwheat, rice should be welcome on your table. Of course, also in reasonable quantities. And remember, drink green tea regularly, as there are no restrictions on its intake when losing weight. Now let’s talk about the most successful combinations of dietary rations and green tea.

How does green tea affect weight loss? The acceleration of metabolic processes is not the only factor influencing weight loss in the arsenal of tea. There are several other useful functions in this direction, we list them:

• mild diuretic properties, contributing, respectively, to the removal of excess fluid. Although among all the products that are usually used in conjunction with green tea, milk does not appear in any way, in order to lose weight, this ceremonial can be bypassed. By adding a little skimmed milk to tea, you can dramatically increase the diuretic effect, more fluid will be excreted. And this tool is a good prevention of swelling of the legs and feet.

• polyphenols, contained in excess in tea, enhance the body’s heat exchange through the efficient processing of deposited fats. Drinking several cups of tea a day, according to scientists, can increase the amount of fat burned by almost one and a half times.

• A decrease in blood sugar also favors weight loss, because it helps not to feel hungry ahead of time. Drink just a cup of tea before meals, and lunch will seem much more satisfying to you, which means you can eat less. Those such a hearty meal, as usual, is also an ally in the fight against excess weight.

The question may arise, how long should green tea be a mandatory component of the diet?  Literally two weeks will be enough for this, the result of the tea diet will be the body’s habit of healthy eating, a moderate diet. You will get a double benefit – first there will be getting rid of excess fluid, and only then the fat will be utilized. Having accustomed the body to a healthy diet, you can sometimes indulge yourself with completely non-diet products, without fear that this will lead to extra pounds of weight.

Green tea extract

Such an extract is made from green, non-fermented leaves of the plant. It is used in the cosmetic and food industries. In cosmetology, masks, creams, shampoos and much more are produced on its basis. Such a widespread use of this product is due to the fact that preparations from tea leaves have a beneficial effect on preserving the youthfulness of the skin and its beauty. In the cosmetic field, the extract is used as a preservative, antioxidant, stabilizer of natural dyes and as a deodorant.

Green tea extract nourishes and moisturizes the skin, improves and strengthens its very structure. It also prevents skin aging, enhancing its protective functions, and at the cellular level it has a general positive effect. In the food industry, green tea extract is used as a natural antioxidant to prevent the oxidation of oils and fats. It is a stabilizer for a number of unstable and rapidly oxidizing compounds.

Contraindications to the use of green tea

While green tea has many health benefits, it should not be consumed in excess. It is generally contraindicated for people with hypotension, as green tea lowers blood pressure. Ulcers are also better off not using green tea preparations.

People with insomnia are also not recommended to get involved in green tea, because it contains caffeine, which stimulates the nervous and cardiac systems.

If you have drunk alcohol, then forget about green tea! If alcohol and green tea are consumed at the same time, then aldehydes are formed, and this will have an extremely negative effect on the kidneys. It is undesirable to use preparations from green tea and on an empty stomach.
