Does tea have caffeine

Billions of people on planet Earth begin the morning with a cup of tea. What for? Of course, in order to shake off the shackles of the carotid and cheerfully enter the coming day. And due to what? Does tea have caffeine? Of course, the main alkaloid of tea is caffeine. The more caffeine in tea - the greater morning energy boost we get.

But does green tea have caffeine? And does white tea have caffeine? A lot of people believe that black tea is much stronger, richer, and caffeinated. Is it so?

tea has caffeine

Contrary to popular belief, tea contains even more caffeine than coffee. If serving espresso prepared from 100% Arabica, accounts for only 1.2% of caffeine, the cup of Assam with high proportion of the substance can have 4%. However, caffeine contained in dry leaf tea, is never completely extracted into the infusion, which means that its actual content in the finished tea will always be slightly lower.

Besides that, tea caffeine acts more mildly than coffee one on the heart and nervous system. This is due to the fact that in tea this alkaloid presents not in pure form, but in combination with tannin. However, caffeine and tannin form a new substance (theine), which is rather slowly absorbed into the blood and is rapidly excreted from the body. Therefore you cannot be poisoned with thein, even if you drink strong tea in very large quantities (up to 12 cups per day).

In order to find out what kind of tea is really stronger - green or black, the public organization ‘EXPERT’ conducted a laboratory comparison between green and black tea of the world trademarks for the first time. It was a sort of a fight in the ring between ‘black’ and ‘green’. Which one will win?

Green tea has more caffeine!

In our study, namely green tea confidently took all the top ranking position of caffeine content in tea. Of all the samples of green teas 8 were the leaders, and the general % surge of caffeine and caffeine content per 1 bag. This clearly indicates higher caffeine content than black tea has. Thus, the content of caffeine in the green tea bag 1 was generally greater 71 mg, and 71 mg of black tea is the limit.

Most caffeinated green tea was a group without flavorings. There Caffeine content in most teas was more than 80 mg. We emphasize that all these figures are given a cup of tea. Not dry tea leaves, namely a cup of tea. This takes into account weight and bags - in fact there are bags on 2 grams, and there are 1.5 grams. Everything was meticulously considered.

Caffeine in green tea

We should also talk about popular white tea. Is it really safe and has no caffeine?

White tea

White tea

There is a common myth that white tea has a minimum content of caffeine compared to other teas, but the content of antioxidants, on the contrary, the maximum. This myth is usually combined with a simplification that caffeine is bad and antioxidants are good - it used as a marketing tool for the promotion of white tea.

White tea does not always have low caffeine content. They are a lot of varieties of white tea, and they all have different caffeine content. There are a variety of very low (about 15 mg / 250 ml) and with sufficiently high caffeine content (about 75 mg / ml).

White tea sort

Higher grade of white tea often has higher caffeine content. This fact is much promoted that white tea contains a minimal amount of caffeine. It is only based on the fact that the infusion of white tea has very light and delicate taste. This may lead to the conclusion that, the lighter and more delicate tea is, the less caffeine exists in it. Although, more often, in fact, it is exactly the opposite.

Among the three most common types of Chinese white tea, Bai Hao Yin Zhen has the biggest caffeine content, although it has a light color and a mild flavor. White Tea Shou Mei, perhaps is the darkest and has the brightest flavor among other white teas, however, it contains the least caffeine. And Bai Mudan is somewhere between these two according to its caffeine content.

White tea with herbs

White tea mixed with herbs loses its caffeine. In fact, most conventional herbs which are used in combination with tea (mint, thyme, linden, etc.) do not have caffeine, and when they are welded with tea, the total content of caffeine is reduced in the mixture. These mixtures may have a very low content of caffeine, especially when white tea is only a small part of the total weight of the mixture. Often you can read all these details on the package.

Conclusion

Nice brown tea

This is an important study because a lot of mothers find that little children can drink green tea, believing that it is good and healthy. Children under two years old should not get caffeine at all! In addition, as we discovered the strongest tea is green one.

Caffeine has a real impact on the body. This effect depends on the dose trapped in the body of the substance: in small quantities it tones, but in large it has a negative impact on the human body. Therefore, the question of whether caffeine is harmful, physicians respond unequivocally: people with certain diseases will find it harmful, it is harmless for healthy people in certain doses, and even useful.

tasty tea

First, let’s talk about those who in any case should avoid caffeine drink - coffee or tea is contraindicated. Caffeinated beverages should not be consumed by people with constantly high blood pressure, as well as suffering from vascular disease and atherosclerosis. Because of coming after ingestion of caffeine increase the acidity it is not recommended for those who suffer from gastritis, gastric ulcer or duodenal ulcer. Even tea with high amount of caffeine is forbidden.

Now, let’s talk about those who are recommended to limit themselves with tea and coffee. Pregnant and lactating women are recommended to limit themselves and drink no more than two cups of tea or one cup of coffee a day, because the embryo absorbs the caffeine, but it takes it more slowly than an adult. Kids can consume tea no earlier than after 2 years old, and in a dose 3 times lower than the rate for adults.

tea or coffee

In a reasonable amount caffeine does not hurt a healthy person. It is even useful. But what is meant by reasonable dose for caffeine in tea?

Doctors believe that safe single dose is 100-200 milligrams of caffeine. The maximum permitted daily dose is 1000 mg of caffeine (1000 milligrams = 1 gram).

As you can see from the study conducted by the NGO ‘EXPERT’, a cup of tea contains maximum 85 milligrams of caffeine. Accordingly, 12 cups of tea a day will not hurt you. However, there is no need to drink tea in such an amount. Therefore, 2-3 cups, which we usually drink per day, will bring only benefits.

tea and coffee

It is widely believed that the fortress and astringency of tea depend primarily on how much caffeine it contains. In fact, tea fortress does not determine the caffeine, and these concepts are not connected. For example, varieties of black Ceylon tea, characterized by strength and richness taste, contain less caffeine than the ‘weak’ and soft Chinese varieties. The dark color of the drink does not indicate a high content of caffeine too.

A lot of people think that strong tea is harmful to the body. In fact, much worse thing is drinking weak tea infusion, which contains few nutrients and plenty of hot water. Whether tea is harmful or good depends not so much on the strength of the drink or the content of caffeine in it, but on the quality of the tea, and whether it is properly brewed.
