Caffeine content in tea and coffee: where is more, how much is in black and green tea

Many tea or coffee drinkers are concerned about where is the most caffeine?

Caffeine & ndash; it is a purine alkaloid that many varieties of plants produce to protect themselves from various insects.

When consumed by humans, it has a strong effect on the central nervous system.

The following symptoms appear:

• Significantly accelerates heart rate;

• Urination becomes more intense;

• heart rate increases;

• Vasoconstriction occurs.

Many plant species contain this excitatory agent in their fruits, leaves, and seeds.

For example, guarana, holly paraguayan, chicory, cola and of course tea. But there is no clear opinion about where the caffeine content is higher. To determine this, you should get a lot of additional information:

• which brand (variety, variety, country of origin, etc.);

• method of preparation (proportion of mixture used, presence of additional additives);

• How long did the brewing process take?

The caffeine level is directly related to the duration of extraction. If brewing has been done for a long time, then the level of alkaloid will be much higher than with short-term exposure. & nbsp;

You should be very careful about the dosage of caffeine-containing beverages.

A day should be limited to a volume of up to 1000 ml, and at a time & mdash; 300 ml.

When the alkaloid level is over 4 g, intoxication of the body occurs, and this affects the functioning of internal organs. If the dose is more than 10 g, then there is a possibility of death. The concentration in the blood increases gradually, and reaches a maximum by the end of the first hour after administration, and excretion takes about 10 hours.

Caffeine in tea: What it depends on

Not only are alkaloids present in coffee mixes, they are also present in natural tea leaves.

The percentage of caffeine they contain depends on many factors, such as the variety, quality, method of preparation, and duration of brewing.

The saturation level ranges from insignificant to very impressive. & nbsp;

The highest percentage falls on the upper leaves, and as it decreases, the concentration of invigorating elements also drops.

In the lowest growing shoots, they are less than 1%.

You can easily find out a good product on the store shelf & mdash; products from high-growing leaves cost significantly more than their counterparts. For example, in & ldquo; An Ji Bai Chai & rdquo;, consisting only of upper leaves and kidneys, the caffeine content will be much higher than, for example, in ordinary & ldquo; Ganpauder & rdquo;.

So-called caffeine-free tea varieties are produced using the outermost leaves. It is worth noting that they also have their own percentage, albeit very small.

To understand what is more caffeine & ndash; in tea or coffee, you need to know how to process raw materials.

The fewer cycles of processing, the better the product retains vitamins and other components, and the more intensively the nerve-stimulating elements are released.

Based on this, we can conclude that the most saturated & mdash; green varieties, because they are least processed. One serving can be from 50 to 80 milligrams, which is more significant than in black teas.

These data show that green does not always mean a less dangerous and more useful product.

Cooking method also matters

Regardless of grade, caffeine-alkaloid levels can be increased or decreased through brewing techniques.

It is much more strongly released from the mixture when using high temperature water.

If you use a liquid that is not too hot, most of it is stored in sheets. But this only works with green varieties, black cannot be cooked without boiling water, so it turns out to be more saturated.

Concentration matters a lot - the more you put in a cup, the higher the level of active elements.

Optimal for green is 4-7 grams per serving, and for black & ndash; half as much. Although a lot depends on the leaves, many popular brands have different percentages with the same volume. The strength will be much lower if there are many flavors in the composition.

Payload

Tea leaves and coffee beans were initially thought to contain different tonic substances.

In the first, alkaloid-tannins were isolated, and in the second, full-fledged alkaloid-caffeine.

Active tannins were found in tea leaves back in the 19th century, and were assigned to a separate species. & nbsp;

Only after 100 years, scientists came to the conclusion that this is the same coffee alkaloid. But the effects on the body were different, so studies were conducted to find the reason for this difference.

It turned out that & laquo; coffee & raquo; human activity is less prolonged, but more intense than & laquo; tea & raquo;.

Brewed grains have a short-term exciting effect, while leaves tone for a long period of time, and in addition remove thirst and refresh. Thanks to these properties, tea drinking traditions have been popular all over the world for thousands of years.

Where concentration is higher: in tea leaves or coffee beans

If caffeine-containing products are used consciously and moderately, their effect on the body will be positive.

The main problem is that their impact on each person can vary significantly - it all depends on the individual characteristics and condition.

For someone to cheer up, half a cup of cappuccino is enough, someone will not feel the effect of two strong espressos. & nbsp;

Find out how much caffeine is in a cup of tea and coffee from the detailed table below:

 

What drinks can I replace

Ivan tea contains a minimum amount of alkaloids, but has a whole list of useful components. & nbsp; All of them have a beneficial effect on human health.

The level of vitamins C and B in the mixture based on this plant is very high (even compared to oranges, lemon and other traditional sources).

There are also rapidly digestible proteins in the composition, and the percentage of harmful acids (purine, urinary, oxalic and others) is extremely low. & nbsp;

Other alkaloid-free herbal collections (based on linden trees , & nbsp; daisies ) also have useful properties, and their use has a positive effect on the physical condition of a person. Such fees can be prepared by hand, purchased at a pharmacy or a specialized store, for example, in a special section of our online store: here .

Finding alternative invigorating blends is simply necessary when the daily intake is approaching 1000.

You can also highlight special products that are made using the decaffeination procedure. These are ordinary mixtures with a minimum percentage of content. Some members of this line have slightly different taste characteristics, as well as identical aroma and color.

What effect does caffeine have on the human body

People experience increased heart rate, vasoconstriction, and heart rate acceleration when exposed to caffeine.

But a fruitful influence cannot be separate from side effects, so you need to monitor the dosage of consumption.

Exceeding the recommended dose of 4 g can adversely affect the functioning of the heart muscle and other internal organs. & nbsp;

Caffeine content in tea and coffee & ndash; comparison table

All figures in this table are averages, and may vary either up or down. It depends on the specific name, product quality and method of preparation (we wrote about all these nuances above). The range between maximum and minimum can be up to 50%.

Compare tea content

Black tea

In this product, the amount of tannin alkaloids can reach 70 mg (average 45) per serving. By this parameter, it is almost 3 times inferior to brewed ground coffee. But it is worth considering the degree of concentration of the mixture in the cup, as well as the duration of brewing and grade, because the values ​ ​ may vary, depending on these factors.

Note that in addition to stimulating crystals, this form contains useful antioxidants that have a beneficial effect on the vital functions of the human body. In combination with them, the impact becomes softer and longer.

Green tea

The average values ​ ​ of the richest green tea are 15-25 percent higher than those of the black most saturated.

To maximize the effect of vigor, we advise you to increase the brewing time and use varieties without flavors. Thus, the fortress will be further increased. & nbsp;

White tea

There is a common myth that this variety does not contain alkaloids, and the content of beneficial antioxidants in it is higher than anywhere else.

However, this is a misconception, because there are many white varieties in which the mileage is very high.

There may be 15 to 75 mg per plate. Therefore, it is difficult to award this variety a position in the list relative to its counterparts.

Nominally, we place it between black tea and green tea, taking into account the average values.

Comparison of coffee content

Caffeine-free coffee

The name of this species is not entirely correct, because it still has its own share of caffeine, although not as significant as in the classic subspecies.

Modern methods of extracting alkaloids from the mixture do not allow one hundred percent to get rid of them. Therefore, one portion of 250 ml accounts for about 0.005 grams.

Natural coffee

When asked how much caffeine is in a cup of green and black tea, you can say & ndash; less than coffee drinks.

It is a mistake to assume that a high concentration of alkaloids & ndash; this is a sign of a good product.

The best grades have a lower percentage.

For example, the difference in saturation between mocha and robusta can be almost twofold.

If we take the average values, then in one serving it will be 0.17 g.

The safest (medically) way to prepare is as follows:

1. Take 20-30 grams of coffee.

2. Fill with 200-250 milliliters of boiling water.

3. Heat until boiling.

The aroma and taste will not change, but the risk of obtaining an increased concentration is reduced. There will be an optimal dosage that will not harm your health.

Instant Coffee

In this case, it all depends on the specific manufacturer, brand and quality of the original raw materials.

For instant coffee, inexpensive varieties are taken, and the beans themselves are chosen smaller, often substandard.

Different blends also affect saturation reduction, so for one cup of freeze-dried product, the average data will be 100 mg.

But these figures have an error factor, because there are both very solid brands and frank imitation of natural goods on the market.

Where is more caffeine

Processed grains and leaves can have completely different effects on the body, depending on the presence of additional impurities and individual characteristics of a person.

The same numbers on paper do not guarantee an identical effect, because the consumer's reaction will depend on many factors.

For example, brewing time, blend quantity, and product quality.

If you compare the amount of caffeine in tea and coffee, the second option will always be more saturated with invigorating trace elements.

If your goal is to quickly increase activity (physical and mental), then we recommend using a richer option. For a long time, you can hold a tea ceremony.

In addition, it minimizes the risk of exceeding the therapeutic norm.

Output

We've taken a closer look at all the popular products that contain nerve-stimulating elements.

It is very important to control the level of their consumption and prevent a significant overdose. You should study the impact of different types of products on your condition and make individual consumption limits. & nbsp;

When calculating the average content, you can follow the table above. However, it is worth taking into account the type, grade and quality of a particular brand, as well as the method and duration of brewing.

Note that the effect of caffeine in coffee and tea in comparison gives a different effect. In the first case, the action is short-term, but intense, and in the second, a much milder and longer effect is observed.

Do not forget about the variety of actions in combinations with additives and flavors. They can either increase or decrease the stimulatory effect on the central nervous system.
