Coffee Facts (How to drink, how much to drink, when to drink)
Coffee is a drink made from roasted coffee tree grains. Due to its caffeine content, it has a stimulating effect.
In nature, there are 73 species of coffee trees - from dwarf shrubs to 11-meter giants. There are two main commercially used types of coffee trees and, accordingly, beans obtained from the fruits of these trees: Coffea arabica L. - Arabica and Coffea canephora Pierre ex Froehn., 1897, or Robusta, sometimes called Congolese coffee. According to different estimates, these two types account for up to 98% of the coffee produced. This volume is divided in the 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 type 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 curved “S” -shaped line, in which usually unburned particles of a coffee berry remain after light roasting.
Robusta is a fast-growing and more resistant to pests than arabica, and grows from about 0 to 600 m above sea level, primarily in 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 coffee in terms of aroma. At the same time, it contains more caffeine, and is also often used in espresso blends, which allows for better coffee crema and reduces the cost of the blend.
Other varieties, such as Liberica and Excelsus, are not of industrial importance. Produced in Asia (Indonesia, Philippines, South India), Kopi Lyuvak or Cape Alamed, the most expensive coffee (about 750 rubles per cup), because for proper preparation must pass the food chain, including the musanga gastrointestinal tract, or Asian palm civet (Paradoxurus hermaphroditus) - a small animal of the civet family. Without the last link, the taste and aroma of this coffee is very mediocre. Recently, a cheaper (10 times) analogue of Kopi Lyuvak, Monkey Coffee (Monkey Coffee), from Taiwanese plantations on the slopes of the Formoz Mountains, appeared with the same complex processing chain of raw grains.
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 encouraging drug, but also one of the oldest: as archaeologists say, a man began to make drinks from plants containing caffeine, even in the Stone Age.
How caffeine invigorates
Caffeine invigorates not because it provides you with additional energy, but because it deceives your 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, preventing true adenosine from reaching them. As a result, your brain does not receive a signal to slow down, and continues to accumulate stimulants.
After some time, 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 no longer keep you awake if you do not increase the amount of drink consumed in order to “hammer” in new receptors.
This whole process takes about a week. During this time, you essentially become addicted to caffeine. Your brain literally changes its structure to work on caffeine — eliminate caffeine, and there will be too many receptor cells to work properly.
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 flu-like symptoms. Therefore, many doctors recommend reducing the amount of caffeine consumed gradually.
Good: it has been scientifically proven that caffeine temporarily improves attention, understanding, memory, reflexes, and even the pace of learning. It also enhances clarity of thinking.
The bad: excessive use of caffeine can cause shaking hands, loss of coordination and appetite, insomnia, and in extreme cases, trembling throughout the body, nausea, rapid heartbeat and diarrhea.
Depending on the individual characteristics, the amount of caffeine consumed also puts a strain on the liver, pancreas, heart and nervous system. And if you are predisposed to ulcers, then caffeine can only worsen the situation.
If you manage to consume caffeine at the same time, equal to 70-100 cups of coffee, then you will have convulsions, and even death may occur.
The average American drinks 210 mg of caffeine daily. This is equivalent to 2-3 cups of coffee, depending on its strength.
The method of making coffee is directly related to the amount of caffeine.
A cup of instant coffee contains 65 mg of caffeine; a cup of coffee brewed in a coffee machine with a strainer contains 80 mg; and a cup of coffee prepared by the "drip method" contains 155 mg.
The four most common sources of caffeine in America: coffee, soft drinks, tea, chocolate - in that order.
The average American gets 75% caffeine from coffee. Other sources include over-the-counter pain killers; appetite suppressants; cold medicine; and some prescription drugs.
What happens to caffeine, which is extracted from coffee in the production of decaf coffee?
Most are sold to companies that produce carbonated soft drinks (cola and so contains natural caffeine, but more is added to it.)
Do you get more caffeine than your kids?
If we estimate on the basis of body weight, then most likely - no.
Children often get as much caffeine from chocolate and drinks as their parents get from coffee, tea, and other sources.
Coffee makers have the right not to disclose their method of decaffeination (caffeine removal).
In 1994, Brazil experienced two cases of severe frosts, which destroyed more than 1 billion pounds of coffee, approximately 10 percent of the supply of the whole world. This was the reason for the world increase in the price of coffee.
The United States consumes about one third of the world's coffee, about 400 million cups per day.
The only type of coffee grown in the United States is Kona, which is grown on the island of Hawaii. This coffee is grown on volcanic soil and has the most intense coffee flavor in the world.
If you drink two cups or more of coffee per day and decide not to drink coffee anymore, then most likely you will have symptoms of discharge (withdrawal syndrome, "othodnyak"), such as headache, nausea, and possibly depression.
The least harmful way to make coffee is to boil it with water instead of using filtering. So it is prepared in the Scandinavian countries.
Freshly roasted coffee beans are usually packaged in breathable (non-airtight) bags to allow the carbon monoxide formed during the roasting process to escape (volatilize). If carbon monoxide does not evaporate, the coffee may not get very good taste.
The Swiss Water decaffeinating process is the least harmful. Check the decanification marks. Other water treatment methods are not so good.
The freshness of a cup of coffee lasts only 10-30 minutes in a heated coffee maker.
The risk of acquiring heart disease increases by 60 percent if you consume between 2 and 5 medium cups of coffee per day, and 120 percent if you consume more than 6 cups per day.
Buy only unbleached brown coffee filters. To whiten the filters, the chemical substance digoxin is used, which can remain as sediment on white filters.
Liquid coffee contains almost two times more caffeine than instant coffee (instant coffee).
Drinks containing caffeine can cause skin dehydration and contribute to premature (early-fast) aging.
Polyphenols in coffee and tannins in tea can reduce the amount of iron available for use by the body. The consumption of one cup of coffee with a hamburger reduces the amount of iron absorbed by about 40 percent, tea by 90 percent.
Caffeine begins to affect your brain in about 30 minutes and lasts from 2 to 6 hours.
Two cups of coffee will lead to an increase in hydrochloric acid in the stomach for at least an hour.
Coffee reduces ulcer healing time.
One cup of coffee or one cigarette will lead to an increase in blood pressure.
Caffeine can affect the absorption of zinc by the body, which in turn can adversely affect the prostate and may reduce sexual desire in some people.
If you reduce the consumption of caffeine, then there will be symptoms of discharge (withdrawal syndrome, "otkhodnyak"). They usually start with a headache, but last only three to five days. Body cells become addicted to caffeine.
If you consume more than 300 mg of caffeine per day, it will overwhelm the Central Nervous System and can lead to insomnia, nervousness, diarrhea and an increase in heart rate.
People with heart disease are more likely to be among those who consume coffee; nevertheless, there is no definitive proof of the relationship. It may simply be that the percentage of people who consume coffee is so much more than those who do not consume, such statistics come out.
Caffeine leads to chemical changes in the cells that cause the release of excess triglycerides into the blood.
Caffeine reduces the body's ability to resist stress.
The coffee tree originally comes from Africa.
In fact, the first people who consumed the drink today known as coffee were the Arabs who did not allow the export of beans. They were eventually smuggled to Holland in 1660 and then to Brazil in 1727.
