Decaffeinated - what it means?
decaffeination — процесс, в результате которого получается продукт (кофе, какао или чай) без кофеина. Декофеинизированный (англ. decaffeinated) — то есть не содержащий кофеин.
Remove all caffeine 100% hardly possible, therefore, usually contain about decaffeinated beverages 1-2% of the initial amount of caffeine.
Speaking directly about the coffee, usually decaffeination process begins with the processing of unroasted (green) beans steaming coffee. Once they are placed in solution, which extracts the caffeine, but leaves other important chemicals beans. The extraction process is repeated several times (eight to twelve times) as long as the grains of not removed until 97% caffeine.
I think many people know, that sort of Arabica coffee contains half the caffeine than Robusta, so taste first is considered more gentle and noble.
Caffeine in coffee.
Since caffeine is a substance affecting the psyche, stimulating the nervous system and stimulates the nervous disorders, it is contraindicated the use of a number of diseases: hypertension, nervous system disorders, insomnia, tachycardia. Caffeine also possesses the property of stimulating cardiac function, as well as a diuretic.
By the way, I remind you, drinking a cup of coffee, do not forget to have a drink after a glass of ordinary drinking water (in order to restore water balance in the body and prevent dehydration). For the same reason I do not recommend "refuel" the coffee in an environment where there is no possibility to fill up "stocks" of water.
With regard to the positive effect of caffeine, many experts believe that it has a positive effect on the human body during exercise: it not only makes us more resistant and increase the supply of energy, but also causes the muscle cells to use more fat as an energy source than it was It is used under normal conditions in the absence of caffeine.
However, as I mentioned, caffeine has a stimulating effect and has an effect on the central nervous system. As a consequence, even healthy people do not abuse the recommended caffeinated coffee in the afternoon, and especially before bedtime. In particular for this reason that more and more people (including me :) prefer decaf.
Decaffeinated coffee: benefit vs harm.
If we talk about the benefits of coffee without caffeine, I say briefly: the use of him is the same (as in conventional nedekofeinizirovannogo coffee), except that the beverage does not have a powerful tonic and stimulating effect. In short, no caffeine - no side effects from it. And if you drink coffee for the taste and aroma (like me :), then this option will suit you perfectly.
In addition, such a beverage can be drunk with virtually no restrictions (including bedtime) - sleep is not affected. Pregnant women are also not prohibited its use.
By the way, coffee without caffeine during pregnancy reduces the risk of low birth weight, as well as reduces the risk of preterm delivery compared with pregnant women who drink regular coffee.
It can not be said about this aspect: as a diuretic, coffee (! Either) accelerates the leaching of calcium. And the higher the dose of caffeine you consume, the greater the risk of osteoporosis - a disease in which bones become brittle.
Mild (compared to the classic coffee) has a diuretic effect decaffeinated beverage. But a cup of coffee (150 ml) without the caffeine content of the last still hovers around 3-4 mg, then the effect will be, of course, weaker than from regular coffee. However, remember to drink water also should not be.
Outputting fluid from the body, coffee lowers blood pressure. It is necessary to remember the people suffering from hypotension, as in normal caffeine coffee compensates pressure drop from a diuretic effect. Thus, decaffeinated brew is hypotonic effect. The lack of this or dignity - to judge each of you.
If we talk about the taste of decaffeinated coffee, as for me, it is no different from the usual (if you buy the ground and quality, from a good producer, I assure hardly someone only to taste can distinguish it from the classic beverage caffeine. Checked many times :). Personally, I always buy the German brand of coffee Dallmayr. It 100% Arabica, light roasting and mild flavor without bitterness.
