Therefore, the effect of green tea on the body may be different. As for the effect of green tea on blood pressure, a one-time dose cannot eliminate it.

Benefit

Due to its composition, tea is able to normalize blood pressure and has a positive effect on the kidneys. Green tea also contains a complex of vitamins necessary for the normal functioning of the liver.

B1 (19 mg) is involved in the processing and synthesis of fats, promotes their rapid dissolution and excretion from the liver;
B2 (1) stimulates the production of bile and accelerates its flow, preventing harmful substances from stagnating in the organ;
C (250) normalizes metabolism between liver cells by increasing vascular permeability and promotes restoration of the organ during cholecystitis and hepatitis.

The presence of catechins in the composition can affect the health of this organ negatively. Scientists from the American College of Gastroenterology have found that a safe dosage for the liver is daily consumption of up to 500 mg of catechins for men and 450–470 mg for women. Exceeding this dosage leads to inhibition of liver function.

This is especially dangerous due to the spread of dietary supplements, in which the catechin content exceeds 700 mg. Daily use of this dosage can lead to the destruction of liver tissue.

Renders tea beneficial effect and with high blood pressure (hypertension). Theophylline (3–4%) is an alkaloid that relaxes muscles and eliminates spasms, promotes the expansion of blood vessels by relaxing their walls and increasing the gaps through which blood flows.

As a result, blood circulation is normalized and blood pressure is reduced. The positive effect on blood pressure is felt immediately after drinking the drink, which helps relieve an attack. With him daily use 1-2 cups per day for hypertensive patients, the severity of the disease may decrease, and pressure surges will stop. Tannin also has a positive effect on pressure, which increases vascular tone.

Caffeine has a diuretic effect. This eliminates swelling and removes excess fluid from the body. It also has a positive effect on the kidneys, as it helps to “wash” them of sand (if any) and resists stagnation of urine. But if you abuse this drink (consuming more than 600 ml per day), the content of salts and acids in the kidneys may increase, which provokes the formation of stones. This happens because when you become dehydrated, your urine becomes more concentrated and the salts it contains accumulate and form sediment.

Maybe, the healthiest drink for tooth enamel, this is green tea with resin, in bags or brewed from leaves.

One of the important aspects of why green tea is beneficial is high content it contains vitamin C (250 mg, while vlimone has 40 mg, and black tea does not have it at all), which can increase immunity and the body’s resistance to bacteria, viruses and infections. You can significantly increase the content of this substance if you drink the drink with lemon. On average, 1 cup of tea contains about 10 mg of vitamin C. Adding one slice of lemon, which contains about 4 mg of this vitamin, can increase its content per cup to 14-15 mg. The vitamin goes into tea when brewed correctly (tea leaves should not be poured with water at a temperature above 90 degrees). The drink is also good for the liver due to its vitamin C content, which normalizes intercellular metabolism in it.

Advice! To maximize the benefits of green tea for the body, pour it not with boiling water, but with water at a temperature of 80–90 degrees and leave for about five minutes.

For one cup you need to use 1 sachet or 1 teaspoon of leaves per 200–300 ml of water. After this, lemon is added. It is better to sweeten this tea with honey rather than sugar, because honey also contains vitamin C. To improve the taste, you can add lemon balm or mint during brewing, which best reveal the taste together with lemon.

With honey

Speaking about the benefits of green tea for the human body, it is worth mentioning the presence of vitamin C (250 mg) in its composition. Thanks to it, the drink helps improve the body's immunity. Imed is also characterized by its vitamin C content (0.5 mg). Regular consumption of a hot drink with honey is suitable for those who need to strengthen their immunity during epidemics of viral infections and cold weather.

When adding honey to a drink, it must be dissolved in an amount of at least 1 teaspoon per cup. In this case, 1 tea bag or one teaspoon of leaves is used for 300 ml of water. To improve the taste, honey tea can be consumed with crushed lemon balm, lemon balm. In addition, honey tea is used by women and men for weight loss, as it satisfies the need for sweets and gives a feeling of fullness.

caffeine and catechin in the composition of such a drink with honey significantly speed up metabolism when consumed daily and are responsible for faster burning of fat deposits and cleansing the liver of fats;
catechins also make tea with honey an effective diuretic, as a result, swelling in men and women is reduced, therefore, body weight and volume are reduced (the same property has a positive effect on the condition of the kidney and blood pressure level);
polyphenols in the drink with honey enhance heat exchange, as a result, more energy is spent on warming the body, obtained by burning fat deposits, and weight loss is stimulated;

Harm

Green tea, the benefits and harms of which are discussed in the material, cannot be taken by everyone.

There is some harm to green tea when consumed with lemon. Since lemon does not contain organic acids, its addition significantly increases the acidity of the drink.

However, this harm from green tea can be reduced if you rinse your mouth or brush your teeth immediately after drinking it. Same The best way remove acidity - drink milk, as its alkaline environment neutralizes acids;
The potential harm of green tea also exists for allergy sufferers. Although green tea is one of the most non-allergic teas, sometimes intolerance is caused by flavors and additives with which it can be enriched (ginseng, hibiscus, jasmine, rose). Quite rarely, a natural flower is used as a flavoring agent, for example, “Jasmine,” because it does not give a strong aroma, and the production of such tea is more expensive, so manufacturers replace it with a chemical analogue. It is to this that the reaction can begin. Regardless of what kind of tea is purchased, in bags or loose leaves, it is important for allergy sufferers to find out what the composition of the product is in order to be sure that it does not contain flavorings;
The ability to lower blood pressure explains the contraindications of green tea for use by hypotensive people. It can greatly dilate blood vessels, causing a drop in blood pressure. This may cause dizziness, weakness, drowsiness, and even fainting. If a man or woman is suspected of having a tendency to hypotension (low blood pressure), then it is better to refuse the drink;
Consuming milk reduces stomach acidity. Milk has an alkaline reaction, and tea acquires the same reaction when milk is added to it. When it enters the stomach, the drink reduces the acidity of gastric juice, resulting in poor digestion of food. This feature explains why green tea is harmful for gastritis with low acidity;
The diuretic effect of the drink is undesirable for kidney stones. Active urine flow can cause stone movement and blockage of ducts in men and women;
The choleretic effect, beneficial for the liver, causes the displacement of stones in the ducts and gall bladder (if present). This can lead to blockage of the ducts;
Catechins in the composition can provide Negative influence liver;
The controversial issue is whether green tea is harmful during pregnancy. Since it relieves swelling, it is useful for expectant mothers. However, potassium and calcium are washed out of the body along with urine. But this happens in small quantities.

If there are no contraindications, the drink can be consumed by men and women in any quantity. But even with contraindications, a person can sometimes treat himself to one cup of this drink.
