How much tea per day to drink. Green tea benefit or harm

How many cups of tea do you need to drink per day to be healthy and full of energy? And what should this tea be: black or green? And why is it useful?

Simon Gibbons, a professor of phytochemistry from the University of London, argues that during the day you need to drink three cups of tea: in the morning, at lunch and in the evening. Tea should be brewed for at least 5 minutes, no matter what type you prefer - packaged or fresh leaves.

About health benefits

  There are four types of leaf tea: black, green, white and oolong. They all contain antioxidants, which have a number of health benefits. You can drink tea with a small amount of sugar or honey, and milk is better to refuse, because its protein, forming compounds with antioxidants, eliminates their beneficial properties.

Stroke risk reduction

The study, which was conducted by Dutch scientists for 15 years, showed a close relationship between regular consumption of black tea (without milk) and a reduced risk of stroke. The researchers concluded that flavonoids (nutrients with antioxidant properties), contained in high concentration in black tea, help reduce LDL production, the so-called. "Bad" cholesterol, which causes a narrowing of the arteries and increases the likelihood of a person having a stroke or heart attack.

Scientists from the United States confirm the findings made in the Netherlands, and recommend to use up to 5 servings of tea per day, which can reduce LDL levels by 11%. Flavonoids also improve the functioning of blood vessels.

Digestive system

Green tea, from untreated tea leaves, helps the digestive system. It stimulates the contraction of the muscles of the intestines and helps control weight, as well as lose those extra pounds. Green tea contains epigallocatechin-3-gallate (EGCG), a compound that slows down the absorption of fat. Green mint tea is also useful. The essential oils it contains help relieve tension in digestive systemthat promotes good digestion. Ginger tea relieves the symptoms of nausea and is usually recommended for a morning intake. Fennel tea helps with constipation, bloating and colic.

Brain function

Black tea helps to concentrate. Researchers at the English University of Northumbria have found that caffeine and L-theanine, contained in black tea leaves, improves cognitive (cognitive) skills. A study by scientists from Imperial College proved that those who drink more than 100 ml of tea (or coffee) per day reduce the risk of glioma, the most common type of brain tumor, with a 34% chance.

Anti-cancer properties

Tea contains polyphenols, antioxidants that prevent the growth of cancer cells. In green tea, their concentration is 8-10 times higher than in vegetables and fruits. A recent study by Taiwanese scientists has shown that consuming just one cup of green tea per day can reduce the risk of developing lung cancer, especially in people who have a genetic predisposition for this. It is also believed that tea can slow the development of prostate cancer and reduce the risk of stomach cancer. Some experts believe that most polyphenols are contained not in black or green tea, but in oolong. They recommend drinking it not too hot (not above 70C), since the temperature of the drink can also affect the development of cancers, such as throat cancer.

The polyphenols contained in tea also help the immune system fight against certain bacteria, improve metabolic processes and skin health. We have already mentioned the beneficial properties of ginger tea above. In addition to the listed properties ginger tea   It has analgesic (in the case of migraine, for example) and anti-inflammatory effects, and also stimulates blood circulation.

Insomnia, depression

It is clear that considering the caffeine content in black tea, it is better not to drink it before going to bed. However, most herbal teas do not contain this component, so if you are tormented by insomnia - a frequent consequence of anxiety or depression, soothing herbal tea is the ideal choice. Try chamomile tea, it contains hezin, a substance that relieves anxiety and promotes sleep. In addition, this tea contains the amino acid tryptophan, which also has a beneficial effect on the nervous system. Tea with lavender will help to calm not only the body, but the “mind and heart”, as well as tea with basil, well known for its sedative properties.

Teeth

Frequent use of black tea can affect the color of teeth, but can also protect them, since polyphenols can reduce the formation of bacteria that cause gum disease and tooth decay. White and green tea have the same useful properties, but fruit teas (because of their acidic environment), on the contrary, can contribute to the destruction of tooth enamel.

    Details

Can I drink too much green tea. Green tea has long been famous for its healing qualities. The most famous is the improvement of metabolism and opposition to colds. Many people are wondering if one cup per day is enough to acquire these miraculous qualities and few people wondered what would happen if there was an excessive consumption of a drink?

How many cups a day will be not good, but harm? And will they go? There are answers to these questions and some of them may turn out to be quite unexpected.
   Let's start with small dosages that are practiced by many green tea lovers. This is a couple cups a day. Cancer specialists will praise you and recommend 2-3 small cups (not large mugs) of a drink per day to improve your health.
   Increasing the dose to 5 cups daily reduces the likelihood of stomach cancer. Well, for those who are trying to lose weight and speed up metabolism, they recommend up to 7 cups of green tea per day. This, however, is not tested in humans. Many other studies show that you can consume even more green tea daily, while receiving bonuses for health. However, this does not mean that the drink should be drunk in buckets. Of course, there is an upper limit - up to 10 cups. We repeat once again: it is the tea cups, which are larger than the coffee cups, but less familiar to all of us, almost half a liter mugs.
   After all the above, it may seem that green tea has an extremely positive effect on the body. This is not true. Like everything else, with excessive consumption of this drink is harmful to the body. For example, tannins that are contained in green and black tea, can lead to a decrease in the absorption of folic acid.
   Therefore, on the dosing of green tea should pay attention primarily to already pregnant women or those who are planning a pregnancy. In these cases, it is recommended to reduce daily intake to two cups or remove green tea from the diet altogether. Also, green tea prevents the absorption of iron, so it is recommended not to drink tea during main meals, but to take between them. You should not drink green tea before bedtime, as it has tonic properties. Also, you can not drink green tea with alcohol.

Indeed, how much can you drink green tea per day? You will say how many people there are as many cups or according to the principle “not to burst”. Again, the question arises: "How many, specifically, a cup or twenty?"

The thing is who is asking this question. On the eve of the session, the student spoke about an extra 4th cup of tea that turned out to be hypnotic for him. My darling girl, my neighbor, wants to lose weight and wants to drink tea instead of food (it turns out 5-7 times a day). Mother-occupied mom prepares a tea ceremony for her husband no more than once a week. It would seem that everything is simple, what goal is pursued, and so much to drink.

Let's turn our gaze to history and traditions. The life of our ancestors was held in constant labor, and they simply did not have time to cook complex dishes from pickles. Tea with milk or cream replaced them with a full meal. It turns out that they drank it 3-4 times a day.

Central Asian tea drinking from a bowl is associated with the hot season. Tea drinking in Siberia takes place to move away from the cold and warm up. Here the amount of tea varies depending on the condition of the person.
  If you follow the traditions of many Asian nations, serve tea with each conversation, you get 10-12 cups daily. With a leisurely conversation, you do not notice how time passes and the bowl is empty. In the kettle with green leaves you can add boiling water several times (the Chinese, for example, do so up to 8 times), while the useful qualities of tea remain, only the caffeine content decreases.

What advises us medicine? “Friend of Medicine” - Russian immunologists and therapists called green tea. They are agreed by the British colleagues, whose studies have confirmed that catechins affect the metabolic rate. To combat excess weight, they recommend drinking 6 cups of green tea a day. Enlightened in this topic will add: "Add physical activity for the desired effect."

Also, doctors confirm the effectiveness of the drink in the fight against cancer, obesity, hypertension, diabetes, osteoporosis.

In case of hypertension one should pay attention not only to the amount of tea consumed (1 cup per day), but also to the correct concentration. Tea leaves should be no more than 0.5-1 tsp. Consume recommended in the morning, so as not to disturb a healthy night's sleep.

But students can drink a glass of freshly after 18.00. Tonic and invigorating properties of green tea will last 6-10 hours.

To improve digestion, tea should be drunk 3 times a day, half an hour before taking main meals, especially meat.

In the heat consume green tea in a cold and hot. Doctors caution, tea can not be a water-changing drink, so a bottle of still water is always at hand.

No matter how much you are advised to drink green tea, gratefully accept this gift of nature. The emerald drink is good both in the heat and in the cold, and at dawn and at sunset; meet friends and immerse yourself in yourself. Drink green tea so much that it is in pleasure, for joy and health!

There are such questions, the answers to which are so multifaceted and even contradictory that it is almost impossible to come to the same correct opinion. In this case, you have to sift a lot of information, sifting out bits of truth from a lot of dirty lentils. That is how you can artistically describe the situation with regard to the variety of tea that is so popular all over the world as Puer. More specifically, then we are talking about the amount of tea drunk per daywhich in no way harm the body. Some argue that more than two cups - already very much. The second, as opposed to the first, argue from personal experience that a safe amount is almost unlimited. To dot the "yo" and understand, how much can you drink puer tea per day, it is necessary to address the obvious facts. First of all, it concerns its composition and complex effects on the body.

Pu-erh is a tea that fundamentally differs from other sorts of fellows in that it is allowed to be consumed even by those who suffer from an ulcer or diseases of the duodenum. From this we get the conclusion that its effect on the stomach and other digestive organs is extremely mild. This is the first definite plus of this variety, which claims that it is really safe to drink it.

The second thing you should pay attention to is the effect on the cardiovascular and nervous systems. Everything is not so simple here, because caffeine is still present in the infusion. The practice of many tea gourmets still claims that its effect is again extremely mild and moderate. It turns out that according to this criterion everything directly depends on the state of health of a particular person. For people with a stable psyche, the amount of Pu'r drunk will not play a decisive role, but for those with nerves shaky, it is better to limit it to a few cups a day.

Everyone knows that Puer has established itself as an excellent natural fat burner. Based on this, it turns out that it is worth drinking for people who are actively involved in sports in order to lose weight. In this case, the infusion can be regarded as a drug and used exclusively within a reasonable, without excessive fanaticism. At the same time, it is desirable to replenish energy reserves in order to avoid exhaustion.

Studies in the 90s in France showed that regular use of puer helps cleanse the intestines, and in a complex. However, the low level of cancer among the Chinese is also indirectly tied to their regular use of this infusion. Unfortunately, serious scientific studies have not yielded more specific results, but the background suggests that Pu-erh is practically the only variety of tea that is completely safe, regardless of the amount of its daily consumption.

If you summarize all these facts, you get an interesting conclusion - you can drink an almost unlimited amount of Pu-erh tea a day, and the only restriction is that its taste can simply be pallied. Despite such bright prospects, it is still better to use it without fanaticism, since any safe thing in excessive quantities, if it does not bring harm, it will still be much less useful.

Finally, it is worth noting that for the safe use of such tea it is extremely important to know how to prepare it properly. Information on how to make it a lot and it is worth listening to it. This is due to the fact that only with proper brewing the infusion will produce the maximum amount of benefit. If you make it too strong, the load on the nervous system may be too high and the tonic effect can only worsen the state of health. Better less, but more often - here perfect recipe   Regarding the amount of Pu-erh tea consumed per day!

Summer thirst is quenched by soda, someone drinks kvass or juice, but in the heat the consumption of coffee and tea, almost the most common in Russia, is noticeably increasing, and how much of these favorite drinks a day can be consumed without harm?

Despite the persistent debate about the hazards of coffee, it is drunk not only more often, but in increasing quantities. Note to coffee lovers - how safe it is for our health - a little lower, but does the “coffeemania” have the opportunity to become a habit?

Here the main problem is caffeine, because some experts believe that it is not only a stimulant, but already a dope. If this is so, then we should figure out whether we use a lot of caffeine and its effect on the body.

Doctors say that the main source of caffeine in our diet is not coffee at all, but tea and coffee, according to VTsIOM, belongs to 2nd place. Other, the most popular caffeine-containing beverages are chocolate, cocoa, and some carbonated and non-alcoholic beverages have its presence.

Therefore, it is necessary to speak not only about the consumption of coffee, but already a whole list of caffeine-containing products that contribute to the consumption of this “dietary supplement”.

For the calculation of caffeine consumed per day, nutritionists introduced, for the convenience of calculating the "eaten" caffeine per day - whether the recommended doses are exceeded, the concept - "caffeine-containing unit" (KE).

1 KE is equal to 1 milligram of caffeine, while 400 milligrams of this “product” is considered a safe dose. If you translate it into products, it turns out that you can drink regular coffee every day - 4 cups, about 200 milliliters, espresso - also four cups, only about 50 to 60 milliliters, each cup has caffeine about 100 mg.

The same amount of caffeine is obtained by drinking strong tea - 2 glasses + 2 espresso and a small jar of energyizer. In Russia, by the way, they consume about 300 milligrams per day, which is considered a normal dose, compared with other countries, not very much.

This system of coffee units clearly shows that the requirement not to give the kids a lot of chocolate, supposedly he has strong properties that arouse their psyche, is a myth.

Therefore, even the standard 100th bar of bitter chocolate contains much less caffeine than a 3-year-old babies can absorb (see infographic).

Maybe this is surprising, but the tea leaf contains caffeine 2 to 5 percent, and the grain of coffee is only within 0.7 - 1.8 (rarely up to 3%), then why coffee is considered a stronger stimulant.

The answer is simple - when converted to weight. Tea for brewing, we take less, it turns out - in the same volume of the drink, the caffeine tea contains less, of course, if there is no habit of "chifit", i.e. to brewing very strong tea.
