Today, there is a huge number of varieties of ground and instant coffee, each with its own unique taste and aroma.
The recipes differ in the method of preparation, the presence of additional ingredients, but the main component of each of them is caffeine, obtained from roasted coffee beans.
The Arabs originally prepared the invigorating drink back in the 12th century. Even then, they learned to add milk, cream and spices to improve the taste.
Nowadays coffee is very popular in Europe, Russia and America. And many inhabitants of our beautiful planet are so used to drinking it in the morning that they cannot imagine a day without a couple of cups.
Beneficial properties
It is worth noting that coffee has a lot of useful properties:
gives a boost of energy;
improves mood;
has a pleasant taste that cannot be confused with other drinks or products;
activates brain activity;
improves memory;

If you drink coffee in moderation, it can be considered a preventative measure against liver disease and Alzheimer's disease. But that's not all.
Caffeine can quickly increase blood pressure in case of hypotension, fight depression and stimulate the nervous system, due to which, with its long-term use, a person’s character and temperament even changes.
Harm of coffee
In the absence of contraindications, coffee does not pose any danger to human health.
However, it is worth considering that it contains active components, the most effective of which is caffeine, which is addictive.
In addition, some categories of people should refrain from drinking this drink, especially in large quantities, as they may experience symptoms associated with the negative effects of coffee. For example, coffee can cause:
- insomnia;
- irritability;
- anxiety;
- increased heart rate;
- severe increase in pressure;
- increased secretion of sweat glands.
Increased sensitivity to caffeine may cause heartburn and increased acidity.
In addition, excessive coffee consumption contributes to the leaching of calcium from bones, and serious overdoses can cause hallucinations and mild mental disorders.
To avoid unpleasant symptoms and side effects, you should follow the norm for coffee consumption and do not get carried away with the aromatic drink.
It is worth noting that instant coffee is more concentrated than brewed coffee. Although in this case, everything depends on the technology of preparation and the brand offering its product.
How much coffee can you drink
The exact amount of caffeine in a cup of coffee is quite difficult to determine, due to the many varieties of this drink.
On average, the recommended dose is 3-4 cups per day. With such consumption, the negative effect of coffee on the human body is practically excluded. Some doctors advise giving preference to black coffee and drinking it without sugar.
