How Much Caffeine in Green Tea
One of the most important misconceptions about tea is that green tea contains less caffeine than black tea and that white tea is the least caffeinated option of all. Forget what you have heard, read this post carefully and discover the truth about caffeine in tea.
The first thing we should know is that the tea, regardless of whether it is green, white, black, etc., comes from a plant called Camellia sinensis and that, therefore, whatever it is processed from, it will continue to be Camellia sinensis.
This great plant has many properties and it contains the component of caffeine or theine. From now on we will use the concept of caffeine or theine interchangeably to refer to this alkaloid.
Is there Caffeine in Green Tea
First of all, we must clarify that theine and caffeine are the same molecules. So why do we differentiate between caffeine and theine? Like all molecules, caffeine interacts with those found. We know that tea contains polyphenols that act as a brake on the action of theine so that its effect is much slower than in the case of coffee and, therefore, less intense but more durable. That is why we know that coffee “wakes us up” much faster, but its effect lasts less in time. Tea, on the contrary, works progressively, keeping us vital and concentrated for a longer time (the effect tends to last from 2 to 3 hours). In short, the only difference between theine and caffeine is the speed of its action and the name.
It is also common to confuse the term “theine” with “theanine”, an amino acid derived from glutamine that provides anxiolytic effects.
Camellia Sinensis uses this component, shipped from the root of the plant, to protect and nourish shoots as they grow. It also uses it as a defense mechanism against insect attacks.
How much theine does the tea have?
Caffeine levels will depend on the type of tea used, the water temperature, the infused time and the time of year in which the leaves have been collected.
Let us now focus on the benefits that Caffeine can bring us.
– Stimulates physical and neuronal activity.
– Reduces degenerative damage.
– It increases metabolic function and helps lose weight.
– Protects the sections of the brain responsible for learning and memory.
– Improves concentration.
– It allows for greater acuity and increases alertness.
Is it discouraged to me?
Since it is a stimulating substance, it is not indicated for people with nerve problems (anxiety, insomnia), people with sensitivity to theine, people with heart problems, hypertensive and pregnant women. Likewise, it is not recommended to take it in conjunction with the intake of diuretic medications, since the xanthan bases that tea possesses could cause an increase in urine output.
Green Tea caffeine content,
The green tea is delicious and rich in antioxidants. However, it has a drawback: its caffeine content, which can surprise and have harmful effects on some people who drink this tea. With the idea of not giving up the health benefits of this tea, here are some simple and effective measures to enjoy green tea without suffering the side effects of caffeine.
How Much Caffeine is in Green Tea,
Green tea drinks are known to be naturally low in caffeine. Some green teas are processed in such a way that they are naturally low in caffeine. Here are three of them: 1) Japanese green tea, fried in a pan or roasted in the oven. The tea is fried at high temperatures and the roasted flavor predominates in this blend. The various types of green tea are fried lightly or well. In those that are fried well, the leaves produce a deeper roasted aroma and taste. 2) Japanese genmaicha is a blend of bancha green tea and genmai (roasted rice again). The proportion of rice and tea is important, the more aromatic the genmaicha tea, the more rice it has. 3) Japanese bancha is a rougher and stronger grade green tea, representing a late season harvest. The bancha is a kind of harvest of the sencha but second season, between summer and autumn, it contains less caffeine. The caffeine per serving comparison is as follows: black tea, 0.05%; gyokuro green tea, 0.02%; sencha green tea, 0.015%; pure green tea, 0.008% and matcha green tea.
Does Green Tea Have Caffeine in it,
Green tea contains caffeine, although at a lower level than black tea or coffee. Green tea contains 40% less theine than black tea and is, therefore, healthier for people with hypertension.
How much Caffeine Does Green Tea Have,
Caffeine is toxic only in large doses. To give you an idea, an adult should consume more than 10 grams in a day to reach the toxicity level. A cup of coffee contains between 80 and 175 milligrams of caffeine, so it would be necessary to consume between 50 and 100 cups of coffee.
It is also interesting to remember that caffeine consumption is not recommended for pregnant or lactating women. The less the better, but the consumption limit is set at 200 mg per day.
Amount of Caffeine in Green Tea (per day Usage)
Get familiar with your tolerance level. Many experts recommend consuming no more than 300 mg of caffeine per day. Compared to black teas, coffee, and carbonated beverages, green tea has been found to provide a source of mild and consistent stimulation with few reports of caffeine side effects, such as nervousness.or headaches. The caffeine in green tea works differently in the body, since unlike coffee, green tea also contains L-Theanine. Theanine is an amino acid that produces a relaxing effect on the brain. Japanese researchers have discovered that theanine is the antagonist of caffeine because it counteracts the effects of caffeine that “alter” the person. Of the 20 different types of amino acids in tea, more than 60% is theanine. This is unique to green and white tea, as the vaporization process does not remove them. Theanine also provides the elegant and sweet flavor of green tea. To realize the benefits of green tea in fighting cancer, researchers agree that drinking 14 to 16 oz. (420 to 480 ml) a day is reasonable. If there is 30 mg of caffeine in a cup with 200 ml (8 oz) of green tea, drinking the recommended amount translates to 60 mg of caffeine per day (much less than 300 mg), and even that level of caffeine can be reduced by following the instructions in this article. The following is a comparison of the caffeine content in various beverages: coffee, 40 to 170 mg (5 oz); cola, 30 to 60 mg (12 oz); black tea, 25 to 110 mg (8 oz); oolong tea, 12 to 55 mg (8 oz); green tea, 8 to 30 mg (8 oz); white tea, 6 to 25 mg (8 oz); decaffeinated tea, 1 to 4 mg (8 oz).
Green Tea has caffeine,
According to food technologist Beatriz Robles, theine is the name given to the caffeine molecule when it is found in tea. “Caffeine is an alkaloid in the methylxanthine family that can be found naturally in many plant species, including the coffee and tea plants, but also in cocoa, yerba mate or Guarana. Different nomenclatures are used to refer to the caffeine in each of them: theine, guaranine, mateine … but we always refer to the same compound, “he clarifies.
This is when it really begins to infuse this whole story because if we talk about the caffeine in tea it must also be said that its variety does not influence so that there is more or less quantity of that molecule. Vega, again: “If you collect a harvest from a plantation and make all the varieties, with the same conditions, the amount of caffeine will be exactly the same.” Something Robles agrees on: “Some research indicates that the variety of tea does not affect too much the amount of caffeine per cup.”
So there are no substantial differences between the different types of tea? According to the scientific opinion of the European Food Safety Authority ( EFSA ), black tea contains 22 mg / 100 ml, while in green it drops to 15 mg / 100 ml. “But the amount of caffeine varies greatly depending on the source consulted so that while EFSA gives those values for black and green tea, other references range from 11 mg / 100 ml in white and green tea to the 18 mg / 100 ml in the black “, qualifies our specialist.
- If drinking tea still has undesirable effects, consider other alternatives. Herbal or floral infusions are not Camellia sinensis and do not contain caffeine. The rooibos and the honeybush, both from South Africa, do not contain caffeine but if they contain high levels of antioxidants, this way you will get the health benefits, less caffeine. Or consider a blend of both (rooibos and green tea) to get half the caffeine content.
- If green tea is left to stand in cold water at 70 ° C (160 ° F), relatively more caffeine and antioxidants such as polyphenols will be released in the infusion within seconds. When warmer water (85 ° C or 185 ° F and above) is used, more caffeine and polyphenols will be removed during the first infusion.
- Take advantage of the polyphenols in green tea, since epigallocatechin gallate is the main antioxidant found in green tea. These antioxidants have been shown to protect the liver, due to their antioxidant and anti-inflammatory properties. Polyphenols are also likely to protect you against certain types of cancer, heart disease, diabetes, and neurodegenerative diseases. Polyphenols are also assumed to help protect against the harmful effects of caffeine. Theoretically, when caffeine is consumed moderately, especially as a natural part of polyphenol-rich beverages, such as green tea, caffeine provides health benefits.
- Theanine is a pain reliever and has been shown to partially prevent the elevation of blood pressure that can occur with caffeine intake.
- Avoid any green tea energy drinks. Many, but not all, versions of green tea soft drinks contain a high concentration of caffeine. Coca-cola’s “Enviga” soda, for example, contains 100 mg of caffeine per serving. It also contains a considerably high amount of sugar that does not provide any benefit for your health (although some brands like “Enviga” do not have sugar).
- If you are pregnant or have a medical problem and have been asked to reduce your caffeine intake, check with your doctor before consuming green tea on a regular basis. While research indicates that green tea is generally a healthy and beneficial drink, in some circumstances, such as with some specific health problems or drug interactions, it is not recommended. .
- Don’t overdo it either. The caffeine in green tea is not the only thing that can be bad in large amounts. The polyphenols found in green tea, when consumed in excess, can cause liver and kidney damage. Don’t drink more than 10 cups a day, and be careful with green tea supplements, which can contain 50 times more polyphenols than found in a cup of green tea.
