And so on).

There is no end in sight to this dispute, since coffee, unlike energy drinks, is a natural product, therefore, it can be both useful and harmful. An analogy can be made with a tomato. This fruit is tasty and healthy, but in patients it can cause an exacerbation of the disease, and if you eat several kilograms of tomatoes at a time, you can get poisoned. We will talk about coffee, the benefits and harms to human health in the presence of any diseases in the article.

Let's start by defining concepts

Coffee is a drink prepared by brewing in a turk (cezve) or coffee machine from roasted and then ground beans coffee tree... It is this kind of coffee that we will discuss further. Instant coffee is a separate topic of conversation, but we will also mention it.

Natural coffe food product is not, since this drink contains very little protein, fat and carbohydrates. However, in coffee, in addition to the well-known caffeine, there are up to 30 biologically active substances. Among them: calcium, phosphorus, vitamin PP, vitamin B2, organic acids, theophylline, etc.

On the effect on the nervous system

Theophylline

This substance, contained in coffee, accelerates blood circulation in the organs and has bronchodilator properties (relieves bronchospasm).

On the effect on the digestive system

Coffee stimulates the secretion of digestive juices. For healthy people, this is not dangerous, but in sick people, or it can lead to trouble.

There is evidence that regular coffee consumption reduces the risk in alcohol abusers.

Coffee contains large quantities of tannins, substances that give this drink a bitter taste. Tannins have a positive effect on the metabolism of certain vitamins, such as "PP" and "C", however, they can interfere with the absorption of some trace elements, for example, iron, which should be taken into account by patients with. In addition, these substances have tanning properties. This effect was used in the medicine of the past in the treatment of stomach ulcers.

The tannins in coffee are neutralized by adding to it.

As you can see, the influence of the described drink on "ulcers" is very contradictory. On the one hand, a cup of coffee in such patients can cause heartburn or abdominal pain, and on the other hand, it can help the ulcer heal. However, the view of modern gastroenterology on coffee is rather negative - with an exacerbation or coffee is contraindicated.

On the effect on the cardiovascular system

The impact of the drink we are discussing on health is very clearly reflected in the state of the heart and blood vessels. Moreover, this effect is due not only to caffeine, but to the rest of the complex of substances included in it.

Caffeine increases the heart rate, causing (an increase in the number of heart beats per minute above normal). For the young, healthy body this is not scary, but even good for athletes, as it leads to an increase in blood flow to the tissues, which somewhat improves athletic performance.

But in sick people, tachycardia can cause life-threatening complications:

• When hypertension - to provoke.
• - significant deterioration of the condition due to an increase in the demand for oxygen in the heart muscle.
• - cause a heart attack up to a heart attack.
• An overdose of caffeine can lead to cardiac arrhythmias, which increases the risk of sudden death by 2 to 3 times. (WHO definition. Sudden cardiac death is an unexpected, unforeseen death of cardiac etiology that occurred in front of witnesses within a short period of time, no more than 1-6 hours from the onset of the first signs of the disease, in a person without the presence of conditions that could currently be fatal ).

• Coffee abuse increases blood levels of total and LDL-cholesterol (""), which contributes to the progression

About false accusations and unjustified hopes

Both critics and coffee aficionados go too far in their enthusiasm and sometimes attribute certain harmful / beneficial properties to this drink, which are not.

• Antioxidant - Coffee contains some antioxidants that protect our bodies from stress. True, in order to get any significant antioxidant effect, you need to drink at least 5 cups a day, so you should not consider it an antioxidant.
• Frying carcinogens - when roasting coffee beans, benzpyrene resins appear in it, which have carcinogenic properties... The deeper the roast, the more tar. But the grain itself, both whole and ground, we do not use inside, and in the resulting drink their concentration is negligible. All gasoline remains in the cup or coffee maker, so given harm very ephemeral, unless, of course, you drink coffee with coffee grounds (cm. ).

About instant coffee

Natural coffee cannot be instant, no matter what advertising tells you about it. The technology for making instant coffee was discovered at the end of the century. However, the first can of this product first rolled off the Nestlé assembly line in July 1938.

Why is instant coffee not good for you?

• At first - instant coffee made not from expensive arabica, but from cheap robusta. Coffee dust, overcooked and substandard beans, as well as other waste are also used as raw materials. coffee production... All this is ground and processed with boiling water under great pressure... The resulting extract is filtered, dried, and then sprayed in special chambers. When sprayed, the drops of the extract solidify, turning into powder. This is instant coffee.
• Secondly, most of the nutrients are destroyed during the manufacturing process. Therefore, in order to provide the necessary taste and aroma of the drink, acorns, as well as various colorants, flavors, stabilizers, etc. are added to instant coffee, and the cheaper the product, the more there are. The usual coffee content in instant coffee powder is 15%, what about the rest?
• Thirdly, caffeine, unlike other active substances, perfectly tolerates all technological stages, so there is more of it in an instant drink (80 g per cup) than in natural (60 mg per cup).

Why isn't decaffeinated instant coffee good for you?

At the beginning of the 2000s, doctors began to actively criticize caffeine. Consequently, people have become interested in decaffeinated drinks. Demand gave birth to supply, decaf coffee began to appear on the market more and more. Only greens can be decaffeinated coffee beans... They are treated with a special solvent called ethyl acetate. This substance is also used in the manufacture of insect stains and artificial leather. Manufacturers say they thoroughly wash their product from ethyl acetate, but where are the guarantees?

findings

As you can see from the above, the harm of coffee is caused mainly by excessive consumption of this drink. One to two cups of coffee a day will improve your mood and invigorate your body. But 4 or more cups a day can be detrimental to your health, especially with prolonged abuse. Coffee is contraindicated for people suffering from heart failure, cardiac arrhythmias, as well as in case of exacerbation of gastric ulcer.

Coffee has long become one of the most beloved drinks in the whole world. Today there is great amount a variety of coffee blends with original taste and aroma, many original recipes making coffee, there is even decaf coffee or with special medicinal additives. But we'll talk about useful and harmful properties most regular coffee - natural or instant, and whether it is worth using it, and in what quantities.

Many legends and gossip have been around for a long time. He is sometimes considered a panacea for all ills, then announced harmful product and recommend limiting use. And the practical experience of using this drink, as well as medical research, prove that everything here depends on the amount of coffee, the method of its preparation and the patient's health.

Coffee composition

The impact of coffee on human health is due to its chemical composition. A variety of substances can be found in coffee beans, including the well-known caffeine and protein, as well as trigonelline, chlorogenic acid, and various mineral salts. The listed substances account for about 25% of the mass of raw coffee beans, and the rest is fiber, oil and water. It should be borne in mind that the amount of these substances and their combination depends on the type of coffee.

Caffeine is the most famous substance in coffee. It is caffeine that regulates and enhances the processes of arousal in the brain. Choosing an adequate dose of caffeine can help increase mental alertness, efficiency, and also relieve fatigue and drowsiness. But consuming large doses of caffeine on a regular basis can lead to addiction and exhaustion. nervous system... Very large doses of caffeine can even cause death in the patient.

Another important ingredient in coffee is trigonelin. This is a substance that is involved in the creation unique aroma coffee, in addition, when roasted, it turns into nicotinic acid, a lack of bark provokes pellagra disease.

An important component coffee - chlorogenic acid found only in raw coffee beans... When roasted, it breaks down and other organic substances are produced, which give the coffee its characteristic astringent flavor. The rest of the acids in coffee, such as malic, citric, acetic and coffee, help to normalize activity gastrointestinal tract and improve digestion.

Bitterness in coffee is a consequence of the presence of tannins in it... Tannins are complex organic substances with a wide spectrum of action, but under the influence of dairy products they break down, so coffee with milk loses its bitterness. In addition, coffee contains up to 20% daily value vitamin P, which has the ability to strengthen blood vessels, and useful minerals such as potassium, calcium, phosphorus and iron.

The negative effects of coffee on the body

That coffee is not the most healthy drink, everyone knows. Doctors strongly recommend not to exceed the recommended doses of its use. More than one to two cups of coffee a day can lead to depression, drowsiness, irritability, and lethargy. This drink is addictive, so often withdrawal does not bring relief when these symptoms occur. A vicious circle is being formed, from which it is not easy to get out.

There are several of the most dangerous areas of exposure to coffee and they must be kept in mind if you want to stay healthy. The nervous system is most often hit... Caffeine constantly "spurs" her up and thus leads to exhaustion.

This negatively affects not only the functioning of the kidneys and ureter, but also the whole organism, which begins to experience a lack of moisture. Therefore, in parallel with drinking coffee, it is important to drink other liquids.

There is a lot of talk around negative impact coffee to work the heart. But in reality, this influence is too small to be taken seriously. Coffee raises blood pressure, but for a very short time and can only harm a person who already has serious heart problems.

Much more serious is the negative effect of coffee on the stomach. After drinking this drink, acidity in the stomach rises, which can cause heartburn, as well as the development of gastritis and ulcers. It is especially dangerous to drink coffee on an empty stomach and with a cigarette, as is often done. To minimize the harm from drinking coffee, simply eat before drinking it.

But even for amateurs culinary masterpieces coffee will help, as it helps speed up the metabolism and part with some extra calories very fast. In addition, coffee is an antioxidant and helps to renew and rejuvenate cells in the body.

Those who want to lose weight with coffee should give up sugary drinks, as well as coffee with cream and desserts.

Contraindications to drinking coffee

There are few contraindications to drinking coffee, and they mainly concern those who simply abuse this delicious invigorating drink. If you drink one or two cups of coffee in the morning, then no substantial harm the body from this will not. But it must be remembered that coffee abuse leads to too many negative side effects.

It is necessary to completely stop drinking coffee for those who have serious diseases of the cardiovascular system. Also, you should not drink coffee for people who have nervous disorders, as caffeine can aggravate them. Refusal from coffee will not harm the elderly, and children are not allowed to drink coffee at all.

Traditionally, pregnant women are not advised to drink coffee. To date, there is no single authoritative opinion about coffee consumption during this period, but this is exactly the situation when it is better to play it safe. Moreover, an increase in pressure, even a slight one, can become a dangerous sign.

Which coffee to choose - ground or instant (Video: "Is there instant coffee?")

Every coffee lover can name more than one reason in favor of the fact that his favorite coffee is the most best coffee in the world. But this, of course, is a matter of taste. But the dispute about which coffee is better to choose, ground or instant, until the end is in sight.

Of course, the content of nutrients in natural coffee is much higher... For example, natural ground coffee has a very high content fatty acidsthat hinder education cancer cells... In instant coffee, their number is much lower. Also, ground coffee contains much more vitamins, as well as potassium and magnesium, which makes it even beneficial for the cardiovascular system. Of course, we are talking about healthy person and moderate use this drink.

What about the content of harmful substances in natural and instant coffee? Instant coffee is the leader here, since its production requires complex chemical processes, as a result of which some harmful substances fall into the composition finished product... And for the preparation of natural coffee, it is enough just to grind the beans, their composition does not change.

The caffeine content is approximately the same in natural coffee and in instant coffee, therefore, this criterion does not allow identifying a leader. But if you want to get decaffeinated coffee, then you will have to use unambiguously instant coffee. Also instant coffee contains fewer calories. If you want to lose weight by drinking coffee, then it is better to give preference to instant coffee.

Today coffee is the most popular drink among people. I think that almost every one of us drinks coffee at breakfast, and someone cannot live without it and uses large quantities. Is it dangerous to drink coffee in such quantities? And, in general, what harm does coffee cause to the body and is there any benefit from it?

The impact of coffee on human health is a favorite topic of controversy between coffee drinkers and coffee opponents. Since it's in vogue today healthy image life, its adherents consider caffeine not very useful and try to consume coffee as little as possible and with a minimum content of caffeine in it. However, doctors from England argue that caffeine is necessary for a person, because if you exclude from his diet all products that contain caffeine (coffee, tea, chocolate, etc.), then the likelihood of headaches and irritability will increase. Therefore, in order to avoid this, a person needs to consume the amount of caffeine that is found in two cups of coffee, three cups of tea, or half a bar of dark chocolate.

Scientists around the world are conducting research on the effects of coffee on health, the results of which do not yet give a definite answer. Some studies show that drinking coffee leads to cancer, while others get rid of diabetes mellitus... 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 energizing effect of coffee, it can be said that the effect of instant coffee is stronger on health, but it is important to consider the excitability of your nervous system. Many people and a large number of drunk coffee does not have any aphrodisiac effect.

Nevertheless, no matter what impact coffee has on health, every year its consumption by people only increases.

The composition of the coffee.
Fresh coffee beans contain about two thousand substances, including water, caffeine 0.65-2.7%, fat 12%, proteins 13%. Roasting of beans changes their composition, while the degree of change in the composition of coffee depends on the degree and duration of roasting. In particular, the amount of caffeine increases to at least 1.3%, and when making instant coffee, this figure rises to 5%. In addition, the coffee bean contains calcium, potassium, iron, magnesium, 30 organic acids necessary for our body, and many others. useful microelements and vitamins. One cup of coffee contains 20% daily allowance vitamin P, which is essential for our blood vessels.

Instant coffee and its harm.
Unfortunately, we do not consume coffee beans as often as we would like. We mainly 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 believe that instant coffee contains significantly less caffeine than in the present. But it's just the opposite, instant coffee, compared to beans, holds the record for caffeine content. Moreover, the more expensive and better quality, as it seems to us, instant coffee, the large quantity it contains caffeine. Therefore, doctors recommend drinking it as little as possible, and still give preference to real coffee beans, prepared according to all the rules. And taste, and aroma, and healthier!

Caffeine is the strongest stimulant of gastric juice secretion, so people with stomach diseases should remember this and not consume coffee on an empty stomach. In addition, instant coffee is a highly acidic beverage, and therefore often causes heartburn when drunk without milk.

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

The harm of coffee.
Drinking coffee is still not harmless. It is not recommended to drink coffee for people suffering from ischemic heart disease and atherosclerosis (although there is evidence that coffee just helps in the fight against atherosclerosis). It is also worth excluding the use of coffee for kidney disease, insomnia, hyperexcitability, hypertension and glaucoma. As you know, you shouldn't drink coffee before going to bed, you can drink the last cup a few hours before bedtime. In addition, coffee is not recommended for children and elderly people.

It should be noted that drinking a certain dose of coffee increases mental and physical performance, improves reaction, increases physical activity, 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 hypnotics and narcotic substances. But the harm of coffee lies in the fact that it is very difficult to determine this very dose on your own, and the effect of caffeine on each person is individual, and depends on the type of the nervous system. Even a small excess of the dose leads to depletion of nerve cells, as well as disruption of the functioning of the body. It is for this reason that coffee should not be given to children, it disrupts the growth and development of the child's body.

Scientists have proven the effect of coffee on cardiac activity, which is expressed in its enhancement, stimulation of the vasomotor center, and increased heart rate. Also, drinking coffee slightly increases blood pressure, so it should not be drunk by people with arterial hypertension and various diseases cardiovascular system, as well as people who have a predisposition to these diseases.

Scientists have proven the fact of the harmful effects of coffee on the body of a pregnant woman. Drinking four or more cups of coffee for a pregnant woman daily increases the risk of termination of pregnancy (33%). However, if future mom drinks less than four cups of coffee a day, the risk of termination of pregnancy quickly decreases, in addition, the risk of fetal death in the womb is reduced to 3%. Coffee is most harmful for periods longer than 20 weeks, so pregnant women are advised to stop drinking coffee during this period.

Coffee inhibits absorption and promotes the washing out of trace elements such as magnesium, calcium, sodium, potassium, etc. Therefore, coffee lovers are advised to use vitamin complexes, and also include in their diet more foods that are rich in the listed trace elements. Especially it concerns fair half humanity. Daily use a woman having more than four cups of coffee increases the risk of osteoporosis (fragility of the bones). Therefore, lovers of this aromatic drink you should consume more calcium, both in vitamin complexes and in the form of foods.

Many of us think that by drinking caffeine-free coffee we are saving ourselves from its harmful effects. Yes, that's right. But then another danger appears. Processing process coffee beans and getting rid of them from caffeine is accompanied by the use of chemicals. Then the question arises: what is more harmful?

It has been scientifically proven that a person's excess of an individual dose leads to the formation of addiction, which manifests itself in the form of severe fatigue, drowsiness and depression. At the same time, the effect of caffeine gradually weakens, which leads to the need to constantly increase the dose in order to achieve the same effect.

The benefits of coffee.
Besides the harmful effects, the benefits of coffee are certainly obvious. Coffee is effective remedy improving mental activity for people engaged in logical activity, improves mental and physical performance. Drinking coffee has a positive effect on human mental health, which is expressed in increased resistance to stress and depression.

Plus, the health benefits of coffee are huge. Drinking two cups of coffee a day helps to reduce the risk of developing cancer of the pancreas, liver, rectum and colon, and in smokers - the risk of blood cancer. Coffee consumption reduces the risk of Parkinson's disease, while women are encouraged to consume 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. Drinking at least six cups of coffee a day can reduce the risk of diabetes by half in men and by a third in women.

Coffee is an effective means of improving reproductive function in men and increases sperm motility.

Coffee has been proven to help with weight loss. Drinking one cup of coffee increases the intensity of your workout in the gym by a third. With a diet and exercise, coffee contributes to the fact that the body begins to use only fats for energy. In addition, coffee is a source of antioxidants that help maintain youth and beauty. Also, coffee helps the absorption of food, so after dinner you can have a cup of this delicious drink.

The beneficial properties of coffee are also used in medicine. Caffeine is used for poisoning with drugs and poisons, vascular spasms, various infectious diseases, cardiovascular insufficiency. Caffeine is the main component of many drugs: Cofetamine, Askafen, Novomigrofen, Pyramine, Novocefalgin, Citramon.

In conclusion, I want to say that everything should be in moderation. You shouldn't make coffee the meaning of your life. The drink should give pleasure and enjoyment of the aroma, and not lead to the appearance of various "sores" due to its excessive consumption.

Most of us start our morning with a cup aromatic coffee... Some people prefer to cook it with their own hands, others drink instant drink...
