 Millions of people start their day with a cup of coffee. It is recognized as a means to awaken from sleep Dreams: how to understand our dreams  Dreams: how to understand our dreams
 , Cheer up, tune in a positive way. But the drink should be consumed with caution. Scholars debate, coffee increases or decreases the pressure, and how this invigorating drink at all affect health.


Composition of coffee

Total coffee contains more than a thousand chemical components. Eight of them are aromatic compounds that give the product a unique flavor and aroma.

The most well-known substance that is found in coffee - caffeine. Caffeine has the ability to stimulate the central nervous system and heart activity constricts blood vessels, is a diuretic.

Caffeine is actively used in pharmacology to create drugs for headaches and stimulants. This is a very popular component of many food additives Food additives - basic classification  Food additives - basic classification
   for weight loss.

In addition to caffeine in the drink, there are other purine alkaloids - theobromine and theophylline - that the excessive use of addictive. Coffee lovers often called "coffee people," and this is no coincidence: an innocent drink as easily addictive, like alcohol.


Harm and benefits

For centuries people argue, bad coffee or useful. This dispute must be infinite, since the drink different effects on people's health.

Due to the high content of caffeine drink helps to cheer up, improves mood, attention, memory and productivity. But the effect of coffee, as well as the effect of any stimulator, briefly. Doctors say that coffee "gives vivacity in credit and have to return the loan with interest." During a surge of activity after drinking a cup of drink you have to pay later drowsiness and dizziness.

Coffee can help a headache, especially if the pain of migraine character. In addition, researchers say that drinking coffee helps reduce the likelihood of developing Type II diabetes, cirrhosis of the liver and even alcohol dependence Alcohol addiction - for no reason, no reason not arise  Alcohol addiction - for no reason, no reason not arise
 . However, these studies still need to be clarified.

There are reports that coffee increases the risk of fractures in women after 45 years, but this data is also not yet confirmed. In particular, it is not clear exactly what dose of the drink is critical. In large doses, coffee is not recommended to use during pregnancy and lactation. Children under 18 are not recommended to give black coffee.

Most controversial is the effect of coffee on blood pressure. In many diseases of the cardiovascular system coffee drinking is strongly not recommended.


Coffee and pressure

It is believed that this drink increases the pressure, and therefore, its use is unacceptable in hypertension, cardiovascular disease and kidney disease. In addition, the consumption of coffee causes palpitations and excites the nervous system. Therefore, those who drink a lot of coffee, often quite irritable and quick-tempered.

At the same time aware of the experiments scientists United States and Britain, which have shown that moderate (up to six small cups a day), coffee consumption has on blood pressure only a small effect. Column tonometer really rises, but not much and not for long, in general, the health does not suffer.

Where is the truth? Perhaps the truth is that the effect of coffee on the body of each person individually.

Many people are afraid to drink coffee, because after eating feel unpleasant symptoms of high pressure. Others argue that coffee, on the contrary, lowers blood pressure. Caffeine contained in the beverage is a diuretic, and removing excess fluid from the body contributes to lowering blood pressure.

However, this effect of drinking coffee - a rarity. Most coffee or no effect on blood pressure or increase it. Much depends on how many people drink coffee. This product is addictive, so "the coffee", accustomed to high doses, pressure surges usually does not happen. At the same time, those who drinks coffee little more sensitive to the effects of caffeine.

According to doctors, the coffee should not be abused. However, even high blood pressure - not a reason to completely give up the drink. To begin to observe their state of health after a cup of coffee - if it does not change for the worse, it may not make sense to abandon the tradition to start with a cup a day. Even better would be to assess the state of health with the help of the tonometer: measuring the pressure to drink and use in half an hour after it, you can objectively assess the impact drink to health.


Hypertension and coffee

Hypertensive patients should probably consider switching to black coffee on the more forgiving drinks such as latte or cappuccino. In addition, you may need to reduce the number of cups of coffee a day - one portion in the morning will be quite enough. Since the pressure in the morning, as a rule, is low, the consumption of coffee is unlikely to lead to tragic consequences.

Of great importance is the choice of varieties of coffee. Contrary to popular opinion, the ground coffee caffeine less than in the soluble. In essence, the instant coffee just is for many a kind of "first aid" means to cheer up quickly, "whip" your brain with caffeine. Ground coffee drinking is not so much for cheerfulness as for pleasure. This drink is more gentle on the body.

If doctors forbid the use of caffeine, the favorite drink would have to find a replacement. This may be, for example, decaffeinated coffee or so-called "coffee beverages" on the basis of barley Barley - a clear sign of impaired immunity  Barley - a clear sign of impaired immunity
   and chicory. Their taste seems rather strange, but the pressure of such surrogates certainly not increase. But tea, particularly green coffee should not be replaced - in tea leaves contain caffeine, no less, and sometimes more than the grains of natural coffee.
