Strong tea is dangerous for the heart?
Strong tea is able to cause tachycardia - the participation and failure of the rhythm of the heart, experts from the University of Hannover were made with such a conclusion. And green in this sense acts stronger black. It has more bioactive substances acting on the walls of the vessels.

By the way, the notorious alkaloid caffeine is contained not only in coffee, but also in tea. But acts in different ways. In coffee, it is in free form and has a powerful exciting effect on the nervous and cardiovascular system immediately. The effect lasts 2 hours. In tea, caffeine is bound by tannies. Therefore, it acts much softer and longer. The effect is achieved gradually and lasts up to 6 hours. But if you drink too strong tea, caffeine will immediately lead to the excitation and nervous system, and vessels.

By the way, the weak infusion of tea reduces blood pressure, and strong (especially with sugar), on the contrary, increases.
Black tea contains a special protein - quercetin, which prevents the formation of blood clots. On the one hand, this is good. But on the other hand, it may damage those who accept anticoagulants (drugs that dilute blood applies to them aspirin). It is also not worth drinking a strong black tea with those who have a stomach ulcer. It can exacerbate inflammation of the mucous and even cause bleeding.

The average for the fortress of chaps is a little knocking the heat. But too strong (and green, and black), on the contrary, increases the temperature! So, during a cold, you should not try to disappear with a patient with a seating stronger.

Opinion of a specialist

Svetlana careful, nutritionist:

- In my opinion, there are no categorically harmful, as well as certainly useful products. Everywhere need a sound approach. That's how tea drinks in the East, this is a whole ritual! Especially brewed, poured into small cups and savor slowly. And we have? Of course, if you drink a feather a half-liter tea mug, not only the heart will become hard.
Both tea and coffee belong to bioactive, saturated enzymes. And therefore act on the human body to a certain extent as a medicine. On the one hand, studies are now appearing that caffeine in reasonable quantities does not increase pressure, on raising rhythm. But, on the other hand, we are talking about reasonable quantities - 2-3 cups of welded coffee per day or 4-5 cups of properly brewed tea.

In one cup of ground coffee is from 90 to 200 milligrams of caffeine (depending on the variety), in one cup of black tea of ​​the middle fortress - from 30 to 70 milligrams. Safe caffeine dose for man - 400 milligrams per day.

Why not get involved in the use of black tea?
The results of the study published in the "New England Journal of Medicine" journal indicate that the excessive use of black tea can have a negative impact on the state of the kidneys.

So, after holding a biopsy of a 56-year-old man with renal failure, the doctors revealed numerous crystals of oxalates in the renal tissue. It is worth noting that oxalates are the components of some products and drinks. Black tea is a rich source of oxalates, and the patient acknowledged that he used 16 cups of ice tea with ice daily, so scientists suggest that this habit could cause renal failure.

Oxalates are contained in many foods and beverages such as dark beer, black tea, instant coffee, chocolate, milk, soy drinks, walnut oil, oatmeal, whole wheat bread, spinach, dry beans and some fruits, such as blueberries, Blackberry and Raspberries.

According to scientists, in the US, the average level of oxalate use per day ranges from about 150 to 500 mg. This is higher than the recommended consumption rate - 40-50 mg / day. As part of black tea about 50-100 mg of oxalates for every 100 ml. Thus, the patient received with renal failure, used more than 1,500 mg oxalate daily.

What number of black tea can become potentially harmful to the human body? According to scientists, it depends on the individual characteristics of the human body, his history of illness and other medical conditions. However, on average, 1 or 2 cups of tea per day are not considered harmful to the body of healthy people, 2-3 cups of tea can be considered a safe norm if a person does not use other products rich in oxalates. So, if a normal healthy adult consumes about 500 mg oxalates per day, the kidneys should be able to derive this dose from the body.

Scientists argue that the most common type of kidney stones is formed by calcium oxalate crystals. Despite the fact that it was not reliably confirmed that the use of a large amount of oxalates from food and beverage causes the formation of kidney stones, doctors recommend some patients with kidney stones to limit the level of consumption of such products and beverages. In addition, kidney problems caused by a high level of oxalate in them can potentially cause renal failure.
