They say that all people are approximately equally divided into tea lovers and coffee lovers. And the first claim that tea - a drink is much more healthy than coffee . Although nutritionists consider this claim controversial, because both there and there is caffeine, which in large doses can be harmful. And the answer to the question, where more caffeine in tea or coffee, sometimes even those who regularly drink these drinks do not know.
How much is caffeine in black tea and coffee?
Caffeine is an active substance that belongs to the class of alkaloids and has the ability to exert a stimulating effect on the human body. And it is contained not only in coffee beans, but also in tea leaves. However, in addition to this there is another alkaloid, tein, so its effect is milder and it seems to people that there is practically no caffeine in it. But those who prefer strong black tea - almost chifir, know for sure that such a drink can cause the same effect as strong coffee.
According to clinical studies, in black tea the caffeine content is quite decent, and its amount can vary depending on when the leaves were harvested, how processed and how the beverage itself was brewed. The same applies to black coffee: the amount of caffeine is determined by the method of roasting, processing of raw materials, preparation of the drink. But in any case, objective data allow us to assert that caffeine in black tea is more than coffee, if we talk about dry brewing and grains. In the first case, this will be 3% of the total weight of raw materials, in the second - depending on the variety from 1.2% to 1.9%.
The amount of caffeine in green tea and coffee
Green tea and green coffee many people find more useful just because they have less caffeine. But this is fundamentally wrong, because in the drink of green tea leaves this substance contains the most. According to this indicator, it is in the first place regardless of the variety and other factors. And even if you compare the amount of caffeine, which contains not in dry tea leaves, but in a ready-made drink, then it will still be here more than in coffee. In one cup of green tea, more than 80 mg of caffeine can be present, whereas in a cup of black tea, there may be a maximum of 71 mg.
As for green coffee , obtained from unroasted grains, the caffeine content in it is almost half as much as in the usual - 30% against 60-70%. But it is worth noting that caffeine in green tea and coffee can also be harmful or useful depending on the dose, that is, on the number of cups of drink consumed during the day.
Where is more caffeine in tea or coffee - the opinion of nutritionists
Nutrition experts say that talking about the content of caffeine in tea and coffee should be based on how much of this substance is in the ready-made drink. After all, in food we use not dry tea leaves and grains, but an aqueous solution in which the caffeine content will in any case be less than in the raw material.
Nutritionists say that:
- in one cup of coffee brewed from natural ground coffee grains, the caffeine content may be higher than in a cup of black or even green, weak tea;
- If it is a question of instant coffee, the caffeine content in it, in comparison with tea, can
be approximately the same; - to get the same dose of caffeine from brewed coffee and tea, in the first case you need 30 ml of a drink, in the second 150 ml.
Can there be zero content of caffeine in tea and coffee?
Both tea and coffee can be decaffeinated, that is, without caffeine. However, this concept is somewhat arbitrary, because it is completely impossible to remove caffeine. In such a drink, it will simply be present in a much smaller quantity.
