6 beneficial and 5 harmful properties of strong tea

Chemical composition of tea

The question of what benefits and harms black tea has for the body is directly related to the set of chemical elements that make up its composition. Black tea contains a rich list of beneficial substances. These include:

• Tannins. They improve blood clotting, promote the absorption of ascorbic acid, and strengthen blood vessels. Tannins accelerate wound healing processes and stimulate the process of cleansing the body of heavy metals.
• Caffeine. It has a simulating effect on the nervous system and gives vigor.
• Amino acids. They participate in the production of hormones and metabolism, slow down the aging process, and strengthen protective functions.
• Carotene. Important for vision. Helps maintain a healthy retina and prevents the development of glaucoma and cataracts.
• Ascorbic acid. Makes the walls of blood vessels stronger. Vitamin C is very useful for teeth - it suppresses the activity of pathogenic microorganisms and helps strengthen tooth enamel. An important element for strengthening the immune system.
• Vitamins B1 and B2. They stabilize the functioning of the nervous system and improve the absorption of iron. They take part in the maturation of red blood cells and the regulation of adrenal function. Necessary to protect the retina from ultraviolet radiation.
• Vitamin RR. Reduces the level of bad cholesterol in the body, takes part in the production of insulin and thyroxine, and activates the enzymes necessary to convert carbohydrates into energy.
• Pantothenic acid. Accelerates healing processes, accelerates hair growth, stimulates intestinal functions. It is of great importance for the condition of the skin.
• Fluorine. Makes bone tissue stronger and is important for caries prevention.
• Potassium. One of the most important microelements - necessary for the full functioning of the muscular, urinary systems, myocardium and blood vessels. Prevents the development of atherosclerotic formations, increases endurance, and normalizes blood pressure.
• Vitamin R. Important for cells, because restores their structure if damaged, improves the functioning of small vessels. Necessary for normal blood circulation, prevents varicose veins and swelling.
• Vitamin K. Participates in metabolism in bone and connective tissues, activates kidney function, and is necessary for the absorption of calcium.

Can children have black tea?

Many mothers often ask their pediatrician: “Can I give my child black tea?” In fact, the common belief that the drink is an excellent drink for a baby is erroneous.

The fact is that caffeine, which is contained in considerable concentration in the tea leaves, is contraindicated for children’s bodies. Regular consumption can lead to increased excitability of the central nervous system, which causes the baby to have restless sleep, moodiness, hysterics, and the inability to sit in one place for a long time.

Pediatricians recommend giving your child special children's teas, which are sold in many pharmacies. Special additives included in the product can additionally have a therapeutic effect:

• chamomile – inhibits inflammatory processes, improves digestion;
• dill or fennel – eliminates increased gas formation, normalizes intestinal function;
• linden – promotes calm falling asleep and prolonged sleep;
• mint – calms the central nervous system, reduces emotional disorders.

Black tea can be given to a child after reaching the age of three. A single amount of drink should not exceed 50 ml. The permissible frequency of use is no more than four times a week. Its concentration should be moderate, since the harm of strong black tea will manifest itself very quickly (see above what adverse symptoms the drink can cause in children).

How many calories are in black tea?

Tea is a low-calorie drink; 100 grams of leaves contain 3-5 calories. However, as a rule, tea is drunk with various additives. Depending on this, the calorie content of the finished product changes.

The following additives increase the calorie content of the drink:

• Sugar (1 tsp) – 18-20 kcal;
• Milk (1 tsp) – 3 kcal;
• Skim milk (1 tbsp) – 5 kcal;
• Lemon (1 slice) – 2 kcal;
• Honey (1 tsp) – 26 kcal;
• Cream (1 tsp) – 10 kcal.

It should be noted that regardless of the type of tea, the number of calories in it does not change.

Types of black tea

When choosing tea, you need to pay attention to its variety. The highest quality is large-sheet, but it is also the most expensive. If you judge by appearance, then in good tea the tea leaves are dark, rich in color, and twisted longitudinally. The brown color of the leaves indicates a violation of the processing technology, and gray-black color indicates a violation of storage conditions.

Also, based on the size of the tea leaves, the following types of tea are distinguished:

• Broken. These are cut tea leaves, the drink from which is characterized by a pronounced color and aroma.
• Fanning. The raw material is small fragments of tea leaves. The drink brews faster compared to using other varieties.
• Tea dust. The brew from it turns out rich, and it is this raw material that is used for the production of tea bags.

Chemical composition of TEA and its healing properties

Tea is the most popular drink in the world. In addition to taste, it also has beneficial properties. Tea appeared in Russia around the middle of the 17th century. They began to import it from China. The word "tea" comes from the Mongolian "tsai". At first, tea in Russia was used mainly as a cure for various vitamin deficiencies, scrofula, gout, colds and other diseases. In addition, tea quenched thirst and even hunger (especially when consumed with various additives).

The tea plant, the most complex in its chemical composition, contains more than 300 complex and simple compounds known to date, and only 260 of them have been identified, that is, a chemical formula has been obtained. At the same time, it should be noted that the chemical composition of fresh and dry leaves is different: in dry tea it is more complex and varied.

The main components of the tea drink are:

• Tannins : catechins, tannin, polyphenols and their derivatives (up to 25-30%), which normalize the activity of the gastrointestinal tract, strengthen the walls of blood vessels, enhance the functions of the adrenal cortex, and have a choleretic and bactericidal effect. It should be noted that tannin promotes the absorption of vitamin P found in tea.
• Protein substances (up to 25%): proteins and amino acids necessary for the functioning of the body, normalize metabolic processes and restore the exhausted nervous system. In terms of protein content, tea is close to legumes. This is why tea is “nutrition”.
• Minerals (up to 7%) : iron, magnesium, manganese, fluorine, nickel, sodium, iodine, copper, which are part of complex compounds. The effect of these minerals is well known. In short: IRON enhances immunity, MANGANESE and FLUORIDE provide hardness to teeth and bones, IODINE normalizes metabolism, increases immunity, physical and mental performance, COPPER improves metabolism, immunity, and vital functions of the body, MAGNESIUM increases bile secretion and has an anti-sclerotic effect. NICKEL activates enzymes that break down glucose. It should be noted that 5 cups of tea contain the daily requirement of nickel, iron, zinc, magnesium!
• Alkaloids (up to 4%) : caffeine, theophylline, theobromine have vasodilating and diuretic properties. The caffeine in tea is called theine. It should be noted that there is more caffeine in tea than in coffee. But the tannin contained in tea softens its effect. Moreover, we almost always dilute tea leaves with water. High-grade teas contain more caffeine. Pressed tea made from coarse raw materials contains virtually no caffeine.
• Essential oils (more than 30 types) make up only 0.02% and determine the aroma of tea. The quality of tea depends on them!
• Resinous substances: resin phenols and acids, alcohols, etc. also determine the aroma of tea.
• Vitamin P (rutin) strengthens the walls of blood vessels, preventing internal hemorrhage and enhances the effect of vitamin C. B vitamins regulate the functions of the endocrine glands, nervous system, and normalize blood sugar. Vitamin PP (nicotinic acid) relieves allergies. Vitamin K promotes normal blood clotting, etc.

Thus, tea is an excellent remedy that strengthens the immune system and has a beneficial effect on the overall metabolism and cardiovascular system.
Green tea is especially useful, which is a well-known regulator of fat and carbohydrate metabolism, as well as an immunostimulant. Green tea is recommended to drink to restore iron levels, for dysentery, rheumatism, hepatitis, stomach ulcers, radiation sickness, sunstroke, to prevent diseases of the lymph glands, bronchi and lungs, etc. /Visitors - 403 for all time, 1 visit(s) ,-ov) today/

What are the benefits of the drink?

Black tea has many beneficial properties. The following can be distinguished from them:

1. Destroy free radicals and reduce cell damage. This effect is due to the presence of antioxidants in the chemical composition. Black tea contains polyphenols (catechins, theaflavins). As a result of the activity of theaflavins, the likelihood of developing diabetes mellitus and obesity is reduced, and the level of bad cholesterol and blood sugar is reduced. The human body needs antioxidants - they improve general condition and prevent the development of chronic diseases.
2. Beneficial effect on heart function. A category of antioxidants called flavonoids is responsible for this. Flavonoids are of great importance for eliminating risk factors for developing cardiovascular diseases. They take part in the regulation of blood pressure, cholesterol levels, and triglycerides.
3. Reducing cholesterol levels. A high level of low-density lipoproteins is dangerous for the development of atherosclerotic plaques, and therefore for the development of stroke and heart failure.
4. Positive effect on intestinal health. The presence of polyphenols in black tea helps to activate beneficial bacteria in the intestines and suppress the proliferation of pathogenic ones. The antibacterial property of green tea allows you to strengthen the protective function of the organ and restore the mucous membrane of the digestive tract.
5. Increased concentration and brain activity. The presence of caffeine and L-theanine (an amino acid) activates the brain. Research has shown that exposure to these substances improves accuracy and alertness.
6. Suppressing the activity of cancer cells. This effect is also achieved due to the presence of polyphenols. These data were obtained based on studies conducted in a test tube: the substances suppressed the growth of existing cells and inhibited the formation of new ones. However, more in-depth studies in humans are required to confirm this information.

When compiling a list of the beneficial properties of black tea, we can name the following:

• toning the body;
• activation of brain activity;
• increasing stress resistance;
• strengthening the immune system;
• protection against inflammatory processes;
• regulation of kidney function, prevention of swelling;
• removal of toxins and heavy metals;
• strengthening the myocardium, blood vessels, protection against atherosclerotic formations;
• stimulation of the endocrine system;
• acceleration of metabolism;
• relieving muscle spasms after physical activity;
• improving blood supply to the brain, eliminating migraines;
• stimulation of digestive processes;
• regulation of blood clotting;
• improved vision;
• strengthening bone tissue and joints;
• accelerates the wound healing process, slows down the aging process.

Benefits of tea

When processed, green tea undergoes a much shorter processing stage, resulting in much more beneficial substances remaining in it, which is why it is more beneficial.

Due to the fact that tea contains many active components, it can have both beneficial and negative effects, and in this article we will tell you all about the benefits and harms of tea. One of the main components of tea is caffeine; it contains enough theophylline and various essential oils.

1. Cleansing from toxins and impurities. Green tea has a pronounced adsorbent effect and perfectly cleanses the kidneys and organs of the gastrointestinal tract. One of the bioactive components of tea is tannin, which allows you to remove heavy metals (mercury, lead, arsenic, antimony and zinc). Green tea contains more tannin and therefore, when cleansing the body of toxins and heavy metals, it provides more benefits.
2. With radiation. Tea is a fairly effective remedy for neutralizing the harmful effects of monitors and televisions and other household appliances. Green tea is more effective.
3. Strengthening blood vessels. Tannin perfectly helps in strengthening blood vessels, since the tannin content is higher in green tea, and therefore its effectiveness is also higher. Thanks to theophylline, blood vessels and capillaries dilate, which promotes blood circulation and blood supply to the human body. Among other things, this bioactive supplement normalizes metabolism and cholesterol levels. Thanks to tannins, the walls of the vessel are strengthened.
4. For diseases of the gastrointestinal tract. Tea has a pronounced antibacterial effect in the gastrointestinal tract. Tannin present in tea, among other things, helps restore and normalize the digestion process.
5. For diseases of the oral cavity. Tea contains fluoride, which helps fight tooth decay and is involved in the restoration of enamel.
6. For the prevention of cancer. Tannin allows you to remove heavy metals, toxins and waste from the body, and also neutralizes the harmful effects of household radiation. Therefore, with regular consumption of tea (green tea is more effective), the likelihood of developing malignant neoplasms .
7. Diabetes. The polysaccharides contained in black tea are involved in the control of blood glucose levels by reducing the absorption of glucose. Green tea for preventive purposes reduces the likelihood of developing type 1 diabetes
8. Losing weight. Green tea regulates the formation of fat in the body and reduces appetite. If you use only regular intake of green tea to lose weight you will not be able to get rid of excess weight , but in combination with physical activity and a healthy lifestyle, it will be most effective. Black tea has no effect on the process of getting rid of extra pounds.
9. Eye diseases. Black tea, or rather its brewing, is used as a remedy for conjunctivitis. To do this, you need to wipe your eyes with a cotton swab dipped in tea leaves. Use a new cotton swab to wipe each eye.
10. Fighting stress. Tea is a good antidepressant, improving mood. When drinking very strong tea, a state similar to a mild form of intoxication may occur. Such conditions only have a harmful effect on our body.
11. Nervous system. Tea can enhance the work of visual analyzers and increase reaction speed, strengthen thinking, improve memory and receptivity of the nervous system.

What harm is done to the body?

The benefits and harms of black tea are incomparable. Speaking about the dangers of the drink, it is necessary to emphasize that negative consequences on the body occur when it is consumed in excess.

These include:

• Disruption of the gastrointestinal tract. When drinking tea in large quantities, it has an irritating effect on the mucous membrane of the digestive system. With unlimited use, cramps in the intestines may occur.
• Negative effect on myocardial function. Abuse of strong brewed tea puts a high strain on the heart.
• Strong tonic effect. This applies to a strongly brewed drink - you should not drink it before bed to avoid insomnia.
• Development of varicose veins, constipation, fatigue.

People with diseases such as:

• ulcer (due to increased acidity);
• glaucoma (due to increased eye pressure);
• anemia (difficulty in iron absorption).

It is forbidden to drink medications with it, as the drink will reduce the absorption of active substances.

Uncontrolled consumption of tea may cause side effects:

• increased excitability of the nervous system;
• panic attacks;
• insomnia;
• arrhythmia, tachycardia;
• headache;
• stomach disorders;
• noise in ears;
• nausea;
• frequent urination;
• tremor of the limbs.

Black tea during pregnancy and lactation

There is no ban on drinking black tea during pregnancy. However, you should not drink more than 3 cups of the drink per day. It is also not recommended for pregnant women to drink strong tea, primarily due to the presence of caffeine in the composition.

If this rule is not followed, there may be negative consequences for the development of the fetus, including low birth weight and caffeine withdrawal syndrome in newborns. A pregnant woman should be careful about her health. If signs of swelling appear, you should temporarily avoid tea and limit fluid intake.

During breastfeeding, it is recommended to drink black tea with milk - this will improve lactation and reduce the concentration of caffeine in the drink.

Is the drink healthy for children?

You should not think that black tea is the best drink for a child. Due to the immaturity of the nervous system, caffeine is contraindicated for children. If a child often drinks strong tea, this will lead to increased excitability, whims, hysterics, and difficulty falling asleep.

There are special teas for children that can be purchased at the pharmacy: chamomile, linden, mint, dill.

How often can you drink?

In the countries of the East, where the tea ceremony was formed, this drink is the main one. You should pay attention to the size of the bowls from which you drink it - these are very small containers.

Harm of sweet tea

Tea itself is considered a fairly healthy drink, but if you add sugar to it, it loses all its beneficial properties. For those who have problems with excess weight, it is not recommended to drink black tea with sugar. This sweet drink contains large quantities of carbohydrates, which are deposited in the body. Scientists have proven that by giving up sugar for thirty days, you can lose a couple of extra pounds. Sugar contains vitamin B1, which greatly affects the nervous system. If you can’t give up sweet tea, you can replace sugar with honey or drink it with sweet dried fruits, such as dried apricots. Dried fruits are very beneficial for the body, as they contain many minerals, vitamins and other substances. For pregnant women, sweet tea poses a particular danger, as its consumption can lead to the development of complications. Some people believe that green tea is more gentle, but they are wrong. If you drink a large amount of any sweet tea, it will have a negative effect on the human body. Tea contains caffeine, which accumulates and can cause toxicosis in a pregnant woman.

Sweet tea can cause digestive problems. For those who have problems with gastrointestinal terrorism, it is best to avoid drinking both black and green tea.
