Coffee – a rich source of caffeine, and other active substances, only one of which – nicotinic acid – has nutritional value. It is produced when roasting coffee beans. A cup of coffee contains about 1 mg of the vitamin. But I have to drink 15 cups of coffee to get enough for an adult daily dose. In general, the nutritional value of the drink is determined to add milk and sugar.
Where you came from coffee
“In the morning without a cup of coffee just can not do without, depending, of course, is not good, but the main thing is that it was to the best.”
Badis
The word “coffee” comes from the Arabic qabwa, which means “exciting.” Legend has it that the angel Gabriel, worried that drowsiness may interfere with Muhammad in achieving its goals, offered him coffee. After drinking it, the Prophet knocked out of the seat 40 knights and captured 40 women.
Coffee and cholesterol
Studies have shown that coffee drinkers who drank more than six cups a day increases the risk of heart disease. However, the risk attributed to the method of preparation of coffee than with the content of caffeine in it. When the coffee is prepared by the method of espresso by passing steam through the coffee powder, or the usual method of Gulf water and followed by boiling (which is especially popular with residents of Scandinavian countries), released two chemical elements that increase the level of cholesterol in the blood and thus the risk of heart disease. These elements – and kofestrol kofeol – constantly present in coffee beans. However, they are removed when the coffee is filtered through the paper in the production of instant coffee, and when preparing coffee in coffee makers.
Coffee and heart disease
When you drink coffee, pulse rate and blood pressure rises a little. But moderate consumption does not lead to high blood pressure (hypertension), even people with high blood pressure can not deny myself the pleasure. Until recently, the conventional wisdom that people who have had a heart attack, should stop drinking coffee or drink only dekofeinirovaniy drink. It was argued that the use of coffee or caffeine involves a change in the heart rate and can cause another heart attack. However, studies in the UK and the U.S., have shown that drinking filtered coffee does not change the heart rhythm in people who have suffered heart attacks. Consequently, they do not need to give up coffee altogether. Coffee as a laxative caffeine itself is not a laxative. Decaffeinated coffee actually weaker, even more than usual. Scientists are still trying to determine which of the 300 organic substances found in coffee beans, are responsible for stimulating bowel movements. However, caffeine is a natural diuretic.
Possible Dangers
Assumption that coffee increases the risk of pancreatic cancer or other malignancies were not confirmed. Furthermore, recent studies suggest that coffee helps prevent colon cancer.
At the same time, women should limit their coffee intake. Recent studies have shown that women who regularly drink more than three to four cups of coffee a day increases the likelihood of brittle bones (osteoporosis) after menopause and at older ages.
Coffee is among the most common causes of migraines. Many also point out that they can not sleep if they drink coffee at night.
Methods dekofeinirovaniya
People who prefer decaffeinated coffee to avoid the exciting action of caffeine, are exposed to other chemicals. Analysis of organic solvents, which are usually used to remove the caffeine, showed that at least two of them are carcinogenic. Older, more reliable, though less effective method uses water to decaffeination, because caffeine is dissolved in water.
Coffee and Women’s Health
Pregnant and lactating women should limit yourself to drink no more than one or two cups of ground cups of instant coffee a day as an embryo absorbs the caffeine, but it takes more slowly than an adult.
As a diuretic, coffee accelerates calcium loss. Large doses of caffeine are associated with an increased risk of osteoporosis – a disease in which bones become brittle.
Coffee and child health
Even caffeine for medicinal purposes is permitted to give only to children older than 2 years, and at a dose of less than 4 times what is found in a cup of coffee.
Large doses of the substance adversely affect the nervous system of the child: first excite and cause insomnia, and then drain the nerve cells, causing the baby becomes lethargic, sleepy, tired quickly. Caffeine increases the rate of breathing increases the load on the heart, causing it to beat in the strong rhythm on the kidneys, increasing the flow of urine, stimulates excessive secretion of gastric juice. It turns out that by teaching the child to “bracing” the drink, you unwittingly, forced to work for a growing body wear!
If a cup of coffee in the morning has become a necessity to wean a child by her uneasy. Indeed, dependence on caffeine is formed at the molecular level! He pushes out of adenosine receptors in the brain, which is the nervous system produces to calm down. And if a person suddenly refused coffee, he feels tired.
To “excommunication” of coffee was painless as possible, the child should drink in the morning cooked in milk chocolate. The nervous system is much less sensitive to the analogue of caffeine – theobromine contained in cocoa powder, and included in its composition magnesium fatigue, nervous tension, promotes better digestion of milk to children much needed calcium. Another note: the less sweetness in the drink, the better – the added sugar in cocoa prevents the absorption of useful minerals.
Caffeine
“Who sat and drank coffee and thought – not bad for them, it? For example, I drink it every day, even sometimes without food, just one coffee. All I know – is that caffeine dilates blood vessels, and what else?”
Denis

Caffeine is found mainly in coffee and tea, but is also present in chocolate, Coca-Cola, the cough and pain medications.
Caffeine stimulates the heart and central nervous system and can improve the ability to mental work, when the brain is inhibited. It also stimulates the production of stomach acid, improving digestion, and helps to hyperventilation.
Although caffeine is relatively nontoxic to him may be addictive. Excess of coffee or tea (cup of tea contains about two-thirds of caffeine present in a cup of instant coffee) causes tremors, sweating, heart palpitations, rapid pulse, insomnia, and migraine. However, do not abruptly abandon coffee as it can lead to headaches, irritability and lethargy.
The caffeine in the drinks and chocolate cause insomnia in children. A child eating all polplitki dark chocolate or drinking two glasses of cola in the evening, it is harder to sleep.

Something interesting
According to the results of the latest research instant coffee may protect against heart disease. This paradoxical conclusion is made by British scientists. It turns out that those who drink more than five cups of coffee a day are less at risk of heart disease. Those who drink at least five cups of coffee, get sick more often. And the greatest number of heart disease in those who do not drink instant coffee.
Unexpected results caused a stir among scientists, many years dealing with this problem, because before Traditionally, overreliance coffee, on the contrary, provokes the risk of heart disease. It is difficult to say definitely, these findings are accidental or natural. Experts who conducted the study, explain their properties is instant coffee, because, prior it was never used.
