Coffee Facts (How to drink, how much to drink, when to drink)
Coffee is a drink made from roasted coffee tree beans. Due to the caffeine content it 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, beans obtained from the fruits of these trees: Coffea arabica L. - Arabica and Coffea canephora Pierre ex Froehn., 1897, or Robusta, which is sometimes called Congolese coffee. According to various 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 variety of coffee, arabica , grows at an altitude of 600 to 2000 meters above sea level. The grains, as a rule, have an oblong shape, a smooth surface, a slightly curved “S” letter line, in which usually after light roasting unburned particles of coffee berries 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 tropical regions of Africa, India and Indonesia. The grains have a rounded shape, color - from light brown to grayish green. Robusta is generally considered less refined in terms of aroma. At the same time, it contains more caffeine, and is also often used in espresso blends, which allows you to achieve better coffee foam and cheapens the mixture.
Other varieties, such as liberica and excels, do not have industrial significance. Produced in Asia (Indonesia, the Philippines, southern India), the Kopi Luwak or Kape Alamid variety is the most expensive coffee (about 750 rubles per cup), because for proper preparation it must go through the food chain, including the gastrointestinal tract of musanga, 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 Luwak, “Monkey Coffee” (Monkey Coffee), came from Taiwan plantations on the slopes of the Formosa Mountains, with the same complicated chain of processing raw grains.
If you start your day with a cup of coffee, then you are not alone. The amount of caffeine consumed by Americans every day is equivalent to 530 million cups of coffee. Caffeine is not only the most popular rejuvenating drug, but also one of the oldest: as archaeologists say, a person began to make drinks from plants containing caffeine back in the Stone Age.
How caffeine invigorates
Caffeine gives vigor not because it supplies you with additional energy, but because it deceives the body, and it begins to think that it 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 the substances that stimulate the brain. Caffeine mimics adenosine and “clogs” receptors, preventing real adenosine from reaching them. As a result, your brain does not receive a signal of a decrease in pace, 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 caffeine and adenosine. After that, caffeine can no longer keep you awake unless you increase the amount of drink consumed in order to “clog” 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 there will be too many receptor cells in it to work properly.
If you abruptly stop using caffeine, your brain will immediately begin to decrease the number of receptors. But it takes about two weeks, during which your body will send out "alarm 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’s 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 consumption of caffeine can cause hand tremors, loss of coordination and appetite, insomnia, and in extreme cases - trembling throughout the body, nausea, palpitations and diarrhea.
Depending on individual characteristics, the amount of caffeine consumed also puts a strain on the liver, pancreas, heart, and nervous system. And if you are prone to ulcers, then caffeine can only worsen the situation.
If you manage to consume the amount of caffeine equal to 70-100 cups of coffee at a time, then you will begin to cramp, 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 produced.
A cup of instant coffee contains 65 mg of caffeine; a cup of coffee brewed in a coffee machine with a filter, 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 are coffee, soft drinks, tea, and chocolate, in that order.
The average American gets 75% caffeine from coffee. Other sources include over-the-counter painkillers; appetite suppressants; cold medicine; and some prescription drugs.
What happens to caffeine, which is extracted from coffee in the production of decaffeinated coffee?
Most are sold to companies that produce carbonated soft drinks (cola already contains natural caffeine, but they add more to it.)
Do you get more caffeine than your kids?
If you evaluate based on 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 producers have the right not to disclose their method of decaffeination (caffeine removal).
In 1994, Brazil experienced two cases of severe frost, destroying more than 1 billion pounds of coffee, approximately 10 percent of the world's supply. This has caused a worldwide increase in the price of coffee.
The United States consumes approximately one third of all coffee in the world, approximately 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 taste of coffee in the world.
If you drink two cups or more of coffee a day and decide not to drink coffee again, then you will most likely have symptoms of withdrawal (withdrawal symptoms, отход к »»)), 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 let out carbon monoxide that forms during the roasting process. If carbon monoxide does not evaporate, then coffee may not taste very good.
The Swiss Water Decaffeination process is the least harmful. Check the decophening 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 is increased by 60 percent if you consume 2 to 5 medium cups of coffee per day, and 120 percent if you consume more than 6 cups of coffee per day.
Buy only unbleached brown coffee filters. For the bleaching of the filters, the chemical substance digoxin is used, which can remain as a precipitate on the white filters.
Liquid coffee contains almost twice as much caffeine as instant coffee (instant coffee).
Drinks containing caffeine can cause dehydration of the skin and contribute to premature (early mild) 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 absorbed iron by about 40 percent, tea by 90 percent.
Caffeine begins to affect your brain after about 30 minutes and lasts from 2 to 6 hours.
Two cups of coffee will increase the hydrochloric acid in the stomach by at least an hour.
Coffee reduces the healing time of ulcers.
One cup of coffee or one cigarette will increase blood pressure.
Caffeine can affect the absorption of zinc by the body, which in turn can adversely affect the prostate and possibly reduce sexual desire in some people.
If you reduce caffeine intake, then symptoms of discharge (withdrawal symptoms, "otodnyak") will occur. They usually begin with a headache, but last only three to five days. The cells in the body become caffeine addicted.
If you consume more than 300 mg of caffeine per day, it will overexcite 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; however, there is no clear evidence of the relationship. It may just 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, which causes the release of excess triglycerides into the blood.
Caffeine reduces the body's ability to withstand stress.
The coffee tree originally comes from Africa.
In fact, the first people who consumed the drink today known as coffee were Arabs who were not allowed to export beans. They were eventually smuggled to Holland in 1660 and then to Brazil in 1727.
The Hills Brothers Coffee was the first commercial company to start selling vacuum-packed coffee in 1900.
Coffee trees require 70 inches of rainfall per year.
Ground coffee oxidizes very quickly and coffee is best bought in vacuum tin cans.
Americans consume 4848 cups of coffee per second, 24 hours a day.
A coffee tree gives about one to twelve pounds of coffee fruit, this is from a six-year-old tree.
It takes approximately 2,000 coffee fruits to produce one pound of coffee, this is a single tree harvest.
The United States is the largest consumer of coffee. About 3 billion pounds a year.
