Coffee, its benefits and harm

To date, coffee is the most popular drink in people. I think almost every one of us drinks coffee at breakfast, and someone at all without it can not live and uses in large quantities. Is it dangerous to drink coffee in such quantities? And, in general, what harm to an organism causes coffee and whether there is from it or him a benefit?



The influence of coffee on human health is a favorite topic of debate between coffee lovers and his opponents. As a healthy lifestyle today, its adherents consider caffeine to be not very useful and try to use coffee as rarely and with minimal caffeine content in it. However, doctors from England claim that caffeine is necessary for a person, because if you exclude from his diet all foods that contain caffeine (coffee, tea, chocolate, etc.), then the likelihood of headaches and irritability will increase. Therefore, to avoid this, a person needs to consume as much caffeine as is contained in two cups of coffee, three cups of tea or half a tile of dark chocolate.

Scientists around the world are conducting research on the effect of coffee on health, the results of which do not yet give an unambiguous answer. Some studies show that drinking coffee leads to cancer, while others - relieves of diabetes. The effect of coffee on the human body is individual and depends on the characteristics of the organism. For example, when considering the invigorating and exciting effect of coffee, it can be said that health is more affected by the effect of soluble coffee, but it is important to consider the excitability of your nervous system. For many people and a large number of drunk coffee does not have any exciting effect.

Nevertheless, no matter what effect coffee has on health, every year people use it only increases.

Composition of coffee.
In the fresh grain of coffee contains about two thousand substances, among which water, caffeine 0,65-2,7%, fat 12%, proteins 13%. Roasting of grains changes their composition, while the extent and duration of roasting depends on the degree of change in the composition of coffee. In particular, the amount of caffeine increases to at least 1.3%, and in the preparation of instant coffee this figure increases to 5%. In addition, the coffee grains contain calcium, potassium, iron, magnesium, 30 organic acids, essential for our body, as well as many other useful microelements and vitamins. In one cup of coffee contains 20% of the daily amount of vitamin P, which is needed by our blood vessels.

Instant coffee and its harm.
Unfortunately, we do not eat coffee in grains as often as we would like. Basically, we use its soluble analogue in glass jars. However, instant coffee does not even remotely convey the taste and aroma of real coffee. Most of us are sure that there is much less caffeine in soluble coffee than in the present. But just the opposite, soluble coffee compared to grains is the record holder for the content of caffeine in its composition. And, the more expensive and more quality, it seems to us, instant coffee, the more caffeine it contains. Therefore, doctors recommend drinking it as sparingly as possible, and still give preference to genuine coffee beans prepared according to all the rules. And taste, and flavor, and healthier!

Caffeine is the strongest stimulant for the secretion of gastric juice, so people suffering from stomach diseases should remember this and do not drink coffee on an empty stomach. In addition, instant coffee is a drink with a high degree of acidity, so it often causes heartburn if you drink it without adding milk.

When preparing natural coffee in grains, the optimal water extraction of substances from grains is 19%, this is exactly what happens when all cooking rules are observed. Manufacturers of instant coffee think more about their benefits, so almost 50% of the water-soluble substances from the grains are completely extracted into the solution, that is, during processing after the release of 19% of the necessary substances, organic acids and other substances that are not responsible for the taste and aroma coffee, but only increase the acidity of this "drink".

Harm coffee.
The use of coffee still can not be called harmless. It is not recommended to drink coffee to people suffering from coronary heart disease and atherosclerosis (although there is evidence that in combating atherosclerosis coffee just helps). Also it is necessary to exclude the use of coffee for kidney diseases, insomnia, hyperactivity, hypertension and glaucoma. As you know, coffee should not be consumed at bedtime, the last cup can be drunk a few hours before bedtime. In addition, coffee is not recommended for children and people aged.

It should be noted that, using a certain dose of coffee, mental and physical performance improves, the reaction improves, physical activity increases, the excitability of the brain, the respiratory center is excited. Again, the optimal dose of coffee reduces fatigue and drowsiness, to a small extent neutralizes the effect of sleeping pills and narcotic substances. But the harm of coffee lies in the fact that it is very difficult to independently determine this very dose, and the effect of caffeine on each person is individual, and depends on the type of nervous system. Even a slight excess of the dose leads to the depletion of nerve cells, as well as to the disruption of the functioning of the body. It is for this reason that coffee can not be given to children, it disrupts the growth and development of the child's body.

Scientists have proved the effect of coffee on cardiac activity, which is expressed in its amplification, the excitation of the vasomotor center, the increase in the pulse. Also, drinking coffee increases the blood pressure slightly, so it should not be drunk to people with arterial hypertension and various diseases of the cardiovascular system, as well as people who are predisposed to these diseases.

Scientists have proven the harmful effect of coffee on the body of a pregnant woman. When four or more cups of coffee are used, the pregnant woman daily raises the risk of abortion (33%). However, if a future mother drinks less than four cups of coffee a day, the risk of abortion quickly decreases, and the risk of fetal death in the womb is reduced to 3%. The most harmful coffee for a period of more than 20 weeks, so pregnant women are advised not to drink coffee during this period.

Coffee inhibits digestion and promotes the washing out of trace elements such as magnesium, calcium, sodium, potassium, etc. Therefore, coffee lovers are recommended to use vitamin complexes, and also include in their diet more foods that are rich in the listed trace elements. This is especially true of the beautiful half of humanity. Daily use of a woman more than four cups of coffee increases the risk of osteoporosis (fragility of bones). Therefore, lovers of this fragrant drink should use more calcium, both in vitamin complexes, and in the form of products.

Many of us think that by consuming coffee without caffeine in it, we rid ourselves of its harmful effects. Yes, that's right. But then there is another danger. The process of processing coffee beans and getting rid of caffeine is accompanied by the use of chemicals. Then the question arises: what is more harmful?

It has been scientifically proven that exceeding a person's individual dose leads to the formation of a dependence that manifests itself in the form of severe fatigue, drowsiness and depression. In this case, gradually the effect of caffeine weakens, which leads to the need to constantly increase the dose in order to achieve the same effect.

Use of coffee.
In addition to the harmful effects, the benefits of coffee are certainly obvious. Coffee is an effective means of improving mental activity for people engaged in logical activities, improves mental and physical performance. The use of coffee positively affects the mental health of a person, expressed in increasing resistance to stress, depression.

In addition, the health benefits of coffee are very large. Drinking two cups of coffee daily reduces the risk of developing pancreatic cancer, liver, colon and rectum, and smokers are at risk of developing blood cancer. Drinking coffee reduces the risk of Parkinson's disease, while women are encouraged to drink coffee in moderation, and men in large quantities. Coffee is a means of preventing diseases such as migraine , liver cirrhosis, hypertension, cholelithiasis, asthma, atherosclerosis, heart attack. The use of at least six cups of coffee daily reduces the risk of developing diabetes in men by half, and in women by one-third.

Coffee is an effective means of improving reproductive function in men, increases the mobility of spermatozoa.

It is proved that coffee helps in the process of losing weight. The use of one cup of coffee increases the intensity of classes in the gym by one third. With diet and exercise, coffee contributes to the fact that the body begins to use to get energy only fats. In addition, coffee is a source of antioxidants, which contribute to the preservation of youth and beauty. Also, coffee helps digestion of food, so after dinner you can drink a cup of this delicious drink.

Useful properties of coffee are used in medicine. Caffeine is used for poisoning with drugs and poisons, spasms of blood vessels, various infectious diseases, cardiovascular insufficiency. Caffeine is the main component of many medications: Cofetamine, Askafen, Novomigrofen, Pyramein, Novocetalfine, Citramon.

In conclusion, I want to say that everything should be in moderation. Do not make coffee the meaning of your life. The drink should give pleasure and pleasure to the fragrance, and not lead to the appearance of various "sores" because of its excessive consumption.
