And anyway, so whether harmful coffee, as many believe? Maybe, from coffee more good than harm? To whom, when and how many
And yet harmless drink coffee cannot be called. Doctors do not recommend to drink it to the people who have coronary heart disease or atherosclerosis (although there is evidence that in the fight against these diseases coffee, on the contrary, it helps). It is not recommended and kidney disease, and elevated anxiety, insomnia, hypertension and glaucoma. Also, do not often drink coffee elderly people.
About when is the best time to drink coffee, there are, for example, such recommendations: do not drink coffee on an empty stomach, and after a very hearty lunch. In addition, it is better to drink it only in the first half of the day (evening Cup of coffee can cause insomnia or just to restless sleep).
And if 2 cups of coffee a day can relieve fatigue, improve attention, increase the reaction speed and physical endurance, large doses (for each person they own), on the contrary, cause irritability and nervousness.
Coffee and a pressure
If you have high blood pressure (hypertension), coffee, you'd better not abuse it. But does coffee increase the pressure in a healthy person? Although this fact remains controversial, probably, to appreciate it all the same. But only for a short time, and that for want of habit. Those who are constantly drinking coffee, this effect disappears.
But when low blood pressure coffee even useful. Many hypotensive just can't live without coffee, using it as a medicine. Though the main thing is to comply with the measure.

However, the beneficial properties of coffee is not over. Here is just a brief list: coffee alleviates asthma and allergies, prevents tooth decay, activates the intestines (as a laxative), prevents the removal of potassium from the body, etc. it is also Noticed that the coffee fans rarely become chronic alcoholics.

No doubt about the fact that, due to the content of serotonin (happiness hormone), coffee is a great antidepressant. Just 2 cups of coffee a day can three times to reduce the risk of depression. In addition, there is a statistics, according to which coffee lovers several times less likely to commit suicide than the opponents of this drink. And the one who drinks coffee, feels more confident, does not suffer from low self-esteem, does not feel groundless fears.
That coffee is useful
Well, about the caffeine they know everything. Most say it is not too useful, but because fans of a healthy lifestyle trying to drink coffee with minimum maintenance. However, doctors claim that caffeine is simply essential. If you deprive a person of all products in which it is contained (coffee, tea, chocolate and so on), it increases the likelihood of headaches and irritability. To avoid this, every day we need this amount of caffeine, which is contained in two cups of coffee, three cups of tea or half tiles of dark chocolate.

Now, it is just the opposite! Soluble according to this index significantly outperforms the coffee beans. Moreover, the better and more expensive instant coffee, the more caffeine it contains.
