Facts about coffee (How to drink, how much to drink, when to drink)
Coffee is a drink made from roasted coffee tree grains. Thanks to the content of caffeine has a stimulating effect.
In nature 73 species of coffee trees - from dwarf shrubs to 11-meter giants. There are two main types of coffee trees used on an industrial scale and, accordingly, the grains obtained from the fruits of these trees: Coffea arabica L. - Arabica and Coffea canephora Pierre ex Froehn., 1897, or robusta, sometimes called Congolese coffee. On these two types, according to various estimates, up to 98% of coffee produced. This volume is divided in a ratio of 70% - arabica, 30% - robusta. The remaining 30 (according to other estimates - 70) species account for only 2% of world coffee production.
The most common grade of coffee, arabica , grows at an altitude of 600 to 2000 meters above sea level. Grains, as a rule, have an oblong shape, a smooth surface, a slightly bent in the shape of the letter "S" a line in which, after a light roasting, the unburned particles of the coffee berry remain.
Robusta species is fast-growing and more resistant to pests than Arabica, and grows from about 0 to 600 m above sea level, primarily in the tropical regions of Africa, India and Indonesia. Grains have a rounded shape, color - from light brown to grayish-green. Robusta is usually considered less refined than coffee in terms of flavor. At the same time, it contains more caffeine, and is also often used in espresso mixtures, which allows you to achieve better quality coffee foam and cheaper mix.
Other varieties, for example, the liberal and the excelsa, have no industrial significance. Produced in Asia (Indonesia, Philippines, southern India), the grade "Kopi Luvak" or "Cape Alamid", is the most expensive coffee (about 750 rubles per cup), because for the proper preparation must go through a food chain that includes the muscular gastrointestinal tract, Or the Asian palm civet (Paradoxurus hermaphroditus) - a small animal of the family of wiverworms. Without the last link, the taste and aroma of this coffee is very mediocre. Recently appeared a cheaper (10 times) analogue of Kopi Luvak, "Monkey Coffee" (Munkie Coffee), from Taiwanese plantations on the slopes of the Formozsky mountains, with the same complex chain of processing of raw grains.
Facts about coffee
If you start your day with a cup of coffee, then you are not alone. The amount of caffeine consumed daily by Americans is equivalent to 530 million cups of coffee. Caffeine is not only the most popular cheerful drug, but also one of the oldest: as archaeologists say, man began to brew beverages from plants containing caffeine, even in the Stone Age.
How Caffeine Helps
Caffeine gives vivacity not because it provides you with additional energy, but because it deceives the body, and he begins to think that he is not tired.
When the brain gets tired and wants to slow down, it produces a chemical called adenosine. This substance enters the receptor cells, where it begins to work, neutralizing substances that stimulate the brain. Caffeine mimics adenosine and "clogs" the receptors, not allowing the real adenosine to reach them. As a result, your brain does not receive a signal to slow the pace, and continues to accumulate stimulants.
After a while, the brain begins to understand what is happening, and increases the number of receptors, so that they are enough for both caffeine and adenosine. After that, caffeine can not support you cheerfully if you do not increase the amount of consumed beverage to "hammer" new receptors.
This whole process takes about a week. During this time, you, in fact, become addicted to caffeine. Your brain literally changes its structure to work on caffeine - exclude caffeine, and to work properly there will be too many receptor cells.
If you abruptly stop using caffeine, your brain will immediately begin to reduce the number of receptors. But it takes about two weeks, during which your body will send "emergency signals" in the form of headache, apathy, fatigue, muscle pain, nausea, and sometimes even in the form of general lethargy and symptoms resembling flu. Therefore, many doctors recommend reducing the amount of caffeine consumed gradually.
Good: it is scientifically proven that caffeine temporarily improves attention, understanding, memory, reflexes and even the pace of learning. It also increases clarity of thinking.
Bad: excessive caffeine consumption can cause hand trembling, loss of coordination and appetite, insomnia, and in extreme cases - trembling in the whole body, nausea, heart palpitations and diarrhea.
Depending on the individual characteristics, the amount of caffeine consumed also gives a load on the liver, pancreas, heart and nervous system. And if you are predisposed to ulcers, then caffeine can only worsen the situation.
If you can use the amount of caffeine equal to 70-100 cups of coffee at a time, then you will get cramps, and even death may occur.
