Black coffee
Natural black coffee is one of the most popular drinks all over the world, many people simply cannot imagine the beginning of a new day without a cup of aromatic invigorating coffee. However, to this day, there are disputes about the benefits and dangers of this product. Numerous studies are being carried out, some scientists once again prove the negative effect of coffee on the human body, others continue to discover its new properties, previously unknown.
It is worth noting that very few people regularly drink real black coffee beans, they mostly prefer its instant analogue, which was invented by the Swiss chemist Max Morgenthaler. This type of coffee is easier and faster to prepare, but in terms of taste, it is significantly inferior to the present. And it is in it that caffeine is contained in large quantities, so coffee lovers are recommended to drink a drink made from beans, it is both tastier and healthier.
The history of the emergence of black coffee
The homeland of the coffee tree is the province of Kaffa in Ethiopia, hence the name of the product itself. The legend goes like this. Once (this was around the 13th century), an Ethiopian shepherd noticed that goats, having eaten the fruits of an unknown tree, began to actively gallop over the hills. After that, he began to brew coffee beans and give to his disciples so that they would not fall asleep during the evening prayer.
As early as the 16th century, black coffee spread to Persia, America, Turkey and Europe. The first European country to start “drinking coffee” was Italy. In Russia, this drink first appeared in 1665. At that time, our country conducted active trade relations with the countries of the Middle and Near East, where coffee was already very popular. Peter I made a great contribution to its popularization in our country, who was used to drinking this drink in Holland.
A little about caffeine
Caffeine is the main active ingredient in coffee and is found in coffee seeds, tea leaves and cola nuts. Scientists have proven that this alkaloid has a strong stimulating effect on the human central nervous system, therefore it is used as a stimulant. Also, caffeine enhances the processes of arousal in the cerebral cortex, so black coffee increases physical and mental performance, physical activity, relieves drowsiness and fatigue. However, an overdose of this product can deplete nerve cells.
It is worth noting that the effect of caffeine on each of us is individual, and depends on the type of human nervous activity. In addition, this alkaloid weakens the effect of narcotic and hypnotic drugs.
Partially refute the opinion that caffeine, being a drug, causes physical and psychological dependence. In fact, black coffee can indeed cause physical dependence, but it would be wrong to call it a drug, because, unlike drugs, it does not cause psychological dependence. Moreover, scientists confirm the benefits of coffee, provided that it will not be abused, i.e. drink no more than 2-3 cups a day.
