Coffee is a drink loved by many. While tea is often controversial and many people really don’t like it, almost everyone drinks coffee. There are many varieties of it: espresso, cappuccino, latte, mocha, ice, Americano and many, many others. It is impossible to resist the sight of such diversity and not try at least something. Everyone knows that coffee is very harmful to the body. However, is this really so?

History of the drink

Coffee has a long history full of secrets and mysteries. They consider it their homeland coffee tree is Ethiopia. It was there that coffee beans were first tasted. Legend has it that one of the monastery shepherds noticed how some red berries gave strength and energy to his goats. He gave these beans to the abbot of the monastery, and he, convinced of their miraculous power, began to supply his monks with coffee beans. However, in those days they were simply chewed without frying or steeping with water.

Later, Arabs came to Ethiopia and made something in the form of candy from coffee beans. They came up with the idea of ​​pouring water over coffee. They began to fry it only in the 13th century AD. Then they learned about the drink in Europe, and they began to buy grains. The spread of coffee trees beyond the Arabian Peninsula was largely helped by the Ottoman Empire and its campaigns in different parts of the world.

There are legends that traders secretly exported coffee beans to various continents during the Great Geographical Discoveries. This helped reduce prices. And now we can drink coffee grown in Brazil, Costa Rica, and Cuba.

What is coffee like?

Many people believe that there is just black coffee and coffee with various additives. Depending on the additives, different names come from them. However, true connoisseurs of this drink know that even black coffee can be different. This is important for the common man who drinks this drink from time to time to know. The fact is that the strength of the drink and all its properties depend on the roasting of the coffee and its type.

According to the degree of roasting they are distinguished (in ascending order):

1. Scandinavian type. The lightest grains, well dried, but only slightly roasted. This coffee has a sour taste and strong aroma and is often consumed with additives.
2. Viennese type. The beans of this coffee are slightly darker than the Scandinavian roast, but the taste is significantly different. Viennese coffee has a sweetish taste and a less intense aroma.
3. American type. Americano lovers can distinguish it from all the others by its aroma alone. This is a drink with a subtle bitterness and a pleasant coffee aroma.
4. French type. Slightly darker than American and has a more bitter, velvety flavor.
5. Italian type. This is a classic coffee recipe. Bitter and rich espresso is obtained from Italian roasted beans.
6. Continental type. Not everyone will like this type of coffee. Very bitter, so-called black espresso. Many people call it coffee-adrenaline.

The higher the roast level, the more tonic properties the coffee has. A drink made from beans of the last two types of roasting is generally not recommended to be drunk after lunch, only in the morning in order to cheer up. It is worth saying that instant coffee is much weaker than brewed coffee. Its properties are less affected by the degree of roasting. Besides, maximum amount only whole grains contain tonic substances. Ground coffee quickly loses them.

In addition to roasting, the type of coffee tree is of great importance. Only two types of it are used on an industrial scale: Arabica and Robusta. The first variety is classic and grows on the Arabian Peninsula. These are the same coffee beans that have an oblong shape and a characteristic curve. This coffee is more expensive, but its aroma and taste are worth it. Robusta is brought from Indonesia, Sri Lanka and India. The grains are round in shape and light in color. Its taste and aroma differs from Arabica, but it contains more caffeine. Robusta is most often used to make instant coffee.

Below we will talk only about black brewed coffee made from Arabica beans. Only the severity of the properties listed below will depend on the degree of roasting. It's worth remembering that various additives change not only the taste, but also the properties of coffee.

Research on the properties of coffee was carried out in 2016. Their result was the following data:

1. Effect on the cardiovascular system. It was previously believed that coffee causes a persistent increase in blood pressure in those who abuse it, and also increases the risk of coronary diseases. It turned out that this drink can actually increase blood pressure by 10 mm Hg, but, on the contrary, in those who rarely drink it. Coffee does not cause a persistent increase in blood pressure for everyone. In addition, it turned out that the drink has no effect at all on the development of coronary diseases.
2. Coffee and diabetes. It turned out that drinking coffee is not only not harmful, but even beneficial for diabetics. Of course, without sugar. The fact is that coffee increases insulin sensitivity and reduces the possibility of developing type 2 diabetes. However, for those treated with insulin, it is better to avoid drinking coffee or adjust the dosage of medications.
3. Nervous system. The caffeine contained in this drink really has a tonic effect. When used infrequently, it increases performance, eliminates drowsiness, helps fight migraines, and even enhances the effect of analgesics. However, if consumed frequently, caffeine can be addictive. Its use no longer has a tonic effect, and its absence, on the contrary, causes drowsiness and apathy.
4. Effect on the digestive system. The study found that coffee reduces the risk of developing liver disease. In persons suffering from alcoholism and regularly drinking coffee, cirrhosis of the liver is significantly less common than in alcoholics who do not drink coffee.
5. Coffee and bones. The drink has a negative effect on the skeletal system. It can leach calcium from bones, making them brittle and increasing the risk of fractures.
6. Oncology. It was previously believed that coffee is a carcinogen that can cause cancer. It turned out that there is no evidence that this drink increases the risk of developing tumor diseases. In 2016, coffee was removed from the list of carcinogens. It was then discovered that it reduces the risk of developing prostate and breast cancer.
7. Coffee and pregnancy. Caffeine is able to cross the placenta. It negatively affects the cardiovascular system of the fetus and can also cause anemia. If you abuse the drink, premature birth or miscarriage may occur.

Contraindications

Based on all of the above, we can say that it is undesirable to drink coffee:

1. Patients with hypertension or secondary hypertension.
2. Suffering from type 1 diabetes mellitus and using insulin for treatment.
3. Elderly people with osteoporosis.
4. Children during the growth and development of bones and teeth.
5. Persons with an excitable type of nervous activity, mental illness and a tendency to aggression.
6. Pregnant at any stage.

Thus, we can conclude that coffee has a lot of beneficial properties, but at the same time, it also has a lot of dangerous ones. Recent studies have made it possible to accurately determine which body structures are affected and how exactly coffee affects them. In the absence of contraindications, its moderate use brings great benefits to the body.

Video: The dark truth about coffee

The majority of the world's population uses coffee as a tasty, aromatic and stimulating drink that relieves fatigue, stimulates mental activity, and increases performance. Its homeland is considered to be Africa (Ethiopia, Kafa province). Coffee began to be cultivated as a crop more than 800 years ago. Initially, this drink was prepared from the dried shell of grains.

Coffee was brought to Europe from Turkey somewhere in the 11th century and until the mid-18th century it was considered a cure for many diseases. At the end of the 18th century and the beginning of the 19th century, serious accusations began to be brought against him. It was its tonic properties that were the main reason for the persecution of coffee. The clergy tried to fight against this drink, calling it “the black blood of the Turks”, which had a “detrimental effect on the souls of Christians.” To the delight of coffee lovers, doctors have dispelled some of the misconceptions and even discovered a number of beneficial properties of coffee.

According to experts, the most aromatic coffee grows in the countries of the Arab East and Africa, although coffee from Colombia and Brazil has conquered the world market. There are different varieties of it, there is even coffee that does not contain caffeine, which is removed from it industrially. Coffee is sold in beans or ready-ground. Instant coffee, which can be powdered, sublimated, or granulated, is currently very popular. It should be noted that instant coffee must contain at least 2.8% caffeine, while beans contain only 0.7%.

The main important component of coffee is caffeine, discovered by the French scientist Runge in 1819, which was its second birth as a medicine. Caffeine is one of the main plant alkaloids, which normalizes and stimulates the functioning of the central nervous system, eliminates apathy, drowsiness, lethargy, relieves fatigue, stimulates and supports the functioning of all vital organs. Caffeine is included in many medications (more than 20), which leads to the restoration of impaired organ functions. Caffeine speeds up metabolism, which helps reduce appetite, the formation of excess fat, and the elimination of toxins.

Coffee beans contain more than 30 organic acids, which cause increased gastric secretion, which promotes high-quality digestion of food. The main acids included in its composition are caffeic, acetic, citric, and malic. Therefore, drinking a cup of this drink after lunch will help with good digestion and, accordingly, rapid evacuation of food from the body.

The content of B vitamins in coffee is also important, which has a positive effect on the regulation of biochemical processes in the human body. The tannins contained in it dry out the gastric mucosa. Therefore, you should not drink it on an empty stomach. It should be noted that green coffee contains chlorogenic acid, which decomposes when the beans are roasted. Chlorogenic acid affects carbohydrate metabolism, which promotes fat burning, lowering blood sugar and, as a result, has a positive effect on the heart muscle.

Research by many scientists has debunked the myth that drinking coffee causes various diseases. It turns out that people who drink coffee, but do not abuse it, are much less likely to suffer from a number of diseases. Reasonable consumption of coffee can reduce the risk of cancer. This effect comes from the presence of antioxidants it contains. The risk of gallstone disease is also reduced.

Coffee increases vitality, stimulates the activity of the adrenal glands, cerebral cortex, and central nervous system. It promotes fat burning, improves digestion, eliminates headaches, replenishes the lack of potassium in the body, reduces the frequency of attacks in asthmatics, and sharpens vision and hearing. Most importantly, it improves performance and mood. Lovers of this drink have a significantly lower chance of developing renal gallstone disease, liver and intestinal cancer. It is believed that coffee relieves serious diseases such as atherosclerosis, Parkinson's disease, and cirrhosis of the liver.

• Folk remedies for coffee treatment:

1. Traditional healers recommend coffee (1-2 cups) for various poisonings (fuel or kerosene fumes, hydrogen sulfide, carbon dioxide, carbon monoxide, poor-quality food). The tannins of this drink help bind the remaining poison and prevent their absorption into the gastric mucosa.
2. An abrasion or wound (even a festering one) can be treated with a 2-3% solution of potassium permanganate or carbolic acid and sprinkled with finely ground coffee powder (at least 2-3 times a day).
3. Strong coffee with lemon juice — good remedy at the initial stage of malaria and the first signs of a cold.
4. Green coffee infusion can treat arthritis, gout, whooping cough, and headaches.

Coffee contraindications

Coffee, due to its caffeine content, is not recommended for various diseases:

• Patients with hypertension, as caffeine can increase blood pressure.
• For peptic ulcer of the duodenum and stomach.
• When consumed in significant quantities, it can worsen diarrhea.
• For glaucoma, since caffeine can increase intraocular pressure.
• If you have osteoporosis, you should limit coffee (caffeine no more than 250 mg per day), as caffeine helps to “wash out” calcium.
• For nervous disorders, since caffeine can increase nervousness, anxiety, and cause insomnia.
• For children.

NOTE:

1. There is an opinion that coffee interferes with the absorption of certain substances, leaches beneficial microelements from the body, and also causes dehydration. Therefore, you should drink it with a small amount of water.
2. There is an opinion that the benefits and harms of coffee depend on the method of its preparation. For example, extreme heat can lead to the formation of unwanted alkaloids. It is also not good for health to drink coffee with (even worse - boiling them together), since coagulation occurs (“thickening”, “curdling”), which makes digestion difficult.

Which coffee to choose

Basic criteria when choosing coffee:

The packaging of real high-quality coffee must indicate the name, its definition, variety, country of origin, enterprise, its address, production date, expiration date, composition and barcode.
Well-known manufacturing companies use tin or glass jars. Plastic containers are usually used by scammers, although there are exceptions, for example, the company Folgers (USA), which sometimes uses plastic containers, and the coffee is quite good.
A paper label glued to a jar should arouse suspicion, since in reputable companies the information is usually painted directly onto glass or tin.
You should not buy coffee at the market or at a kiosk, but rather buy it in specialized or branded stores.
You need to carefully look at the quality of the packaging and the conditions of its storage in the store.
If you cannot translate the information from the label, then you should ask the seller for a certificate containing all the necessary information in Russian.

How to spot fake coffee. The main ways to falsify it:

1. Mixing different varieties and selling at the price of high-grade.
2. Packaging of surrogates or products with expired expiration dates.
3. Re-sticking labels.

Adulteration is carried out mainly in ground coffee. For this, various root vegetables (carrots, beets, etc.), roots (dandelion, etc.), seeds are used. leguminous plants(lupines, beans, peas, etc.), plant substances rich in sugar (burnt molasses sugar, sugar beets, wine berries, etc.), substances rich in starch (malt, wheat, barley, rye, acorns, etc.), as well as substances rich in fat (various nuts). Chicory is most often used to falsify it.

Counterfeiting of beans is done by mixing high-grade varieties (Arabica, mocha) with lower grade coffee beans. In addition, there are methods of artificially reproducing coffee beans from dough (wheat, barley, etc.), as well as from ground olive pits and even from clay, which were then sprayed with a solution of molasses sugar, fried, tinted, and mixed with natural coffee.

Preparing ground coffee

The beans can be ground with either a manual or electric coffee grinder. The finer the grind, the greater the solubility of aromatic substances in coffee, which is 1-4 minutes for fine grinding, 4-6 minutes for medium grinding, and 6-8 minutes for coarse grinding. You should not grind very finely, as the drink made from this powder will be too bitter and cloudy. In addition, such grinding is not suitable for coffee makers and coffee machines in which water drips through a sieve with coffee. Fine grinding is quite suitable for making oriental coffee. Medium grind is suitable for different ways brewing, and coarse grinding is suitable for brewing in a coffee pot.

To fry green grains, you need to heat a frying pan, pour in the grains and fry them over low heat, stirring continuously, until dark brown. Burnt and undercooked grains will spoil the taste of the drink. Some people add 3-4 grams of oil when roasting grains (per 100 grams of raw grains). If the water used for brewing is hard, the coffee beans can be roasted a little more.

How to make coffee correctly

The ideal way to make coffee

There are countless ways to prepare it. Ideally, coffee is prepared in, or a Turk (with a thickened bottom), when using soft water(without salts and impurities). You need to boil water in a Turk, add coffee (1-2 tsp per 1 glass of water), add a little sugar, which slows down the boiling process, and cold water. The Turk is then placed in a brazier (an iron box filled with river sand). After a few seconds, foam appears - the drink is ready!

Necessary rules for brewing coffee at home:

• Before starting cooking, the pot (or coffee pot) must be heated by rinsing the container with very hot water.
• Pour ground coffee into a pot (or coffee pot), add boiling water and heat over low heat.
• It is advisable not to bring coffee to a boil, since boiling deteriorates its taste and reduces its beneficial properties.
• As soon as bubbles appear, remove from heat and let sit.
• It is better to drink coffee immediately after brewing, before it cools down, otherwise the taste and aroma will change.

How to properly store coffee at home

Ground coffee extremely demanding on storage conditions. To preserve its exquisite taste and aroma, it should be placed in an opaque and tightly closed container. For long-term storage, it is better to freeze it in the freezer.

Coffee beans retains its properties for a longer time. Therefore, it is recommended to grind it before use. But if the aroma does not appear during the grinding process, then you can “revive” it: rinse it with a stream of cold water and then, stirring constantly, dry the grains in a clean frying pan. If this doesn't help, you'll have to buy it again. Shouldn't buy a large number of, since roasted grains are not stored for a long time.

Thus, beneficial substances are gradually washed out, while the water balance is completely disturbed. The result is skin diseases, weakness and rapid aging of cells

• Some scientists, probably paid by coffee companies, claim that coffee is at least harmless, and in some places even benefits the body (reduces the risk of stroke, diabetes, cirrhosis of the liver, depression, kidney stones, etc.).
• Others, who are paid by competitors (tea or juice producers, for example), talk about the terrible destructiveness of this drink for our health.

There is no end in sight to this dispute, since coffee, unlike energy drinks, is a natural product, therefore, it can be both beneficial and harmful. An analogy can be made with a tomato. This fruit is tasty and healthy, but in patients with gout 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 harm to human health in the presence of any diseases in the article.

Let's start with the definition of concepts

Coffee is a drink prepared by brewing roasted and then ground coffee beans in a cezve or coffee maker. This is the kind of coffee we will discuss further. Instant coffee is a separate topic for discussion, but we will also mention it.

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

About the effect on the nervous system

Theophylline

This substance contained in coffee accelerates blood circulation in 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 for patients with stomach ulcers, gastritis or pancreatitis it can lead to trouble.

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

Coffee contains tannins in large quantities, substances that give this drink a bitter taste. Tannins have a positive effect on the metabolism of some vitamins, such as PP and C, but may interfere with the absorption of some microelements, such as iron, which should be taken into account in patients with anemia. In addition, these substances have tanning properties. This effect has been used in past medicine to treat stomach ulcers.

Tannins in coffee are neutralized by adding milk to it.

As you can see, the influence of the described drink on “ulcer sufferers” 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 promote the healing of ulcers. However, the view of modern gastroenterology on coffee is rather negative - in case of exacerbation of gastric ulcer or duodenal ulcer, coffee is contraindicated.

About the effect on the cardiovascular system

The impact of the drink we are discussing on health is very clearly reflected in the condition 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 tachycardia (a higher than normal number of heart beats per minute). For a young, healthy body, this is not scary, but for athletes it is even good, 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:

• In case of hypertension - provoke a hypertensive crisis.
• In case of heart failure, there is a significant deterioration in the condition due to an increase in the need of the heart muscle for oxygen.
• In case of ischemic disease, it can cause a heart attack or even a heart attack.
• An overdose of caffeine can lead to cardiac arrhythmia, 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, occurring in the presence 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 ).

A few more facts about the benefits of coffee

What can motivate us to drink one or more cups of coffee?

• Regular consumption of even one cup of coffee per day can reduce the risk of cardiovascular death (stroke, heart attack, fatal blockage of an important vessel) by 24%. Proven by a joint study by scientists from Madrid and Harvard.
• There is scientific evidence that regularly drinking coffee can reduce the risk of Alzheimer's or Parkinson's disease, with coffee reducing the risk of Parkinson's disease by 500%.
• Coffee reduces the activity of microorganisms that cause caries. True, to reduce the risk of caries you need to drink this drink without sugar.
• Coffee may help reduce some allergies because it reduces the formation of histamine in the body (see allergy pills)

Fun fact: Research has shown that the best release of antioxidants and caffeine comes from brewing coffee at room temperature (see Don't brew coffee with boiling water).

A few more facts about the health risks of coffee

When and for what reasons should you avoid drinking coffee?

• Pregnant women should drink coffee very carefully. Drinking four or more cups per day increases the risk of miscarriage by 33%. However, 1 – 3 cups per day reduces the likelihood of intrauterine fetal death by 3%.
• In menopausal women, 4 or more cups per day increases the risk of osteoporosis.
• Excessive coffee consumption increases the blood levels of total and LDL cholesterol (“bad cholesterol”), which contributes to the progression of atherosclerosis.

About false accusations and unjustified hopes

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

• Antioxidant - Coffee contains some amount of antioxidants that protect our body from stress. True, to get any significant antioxidant effect, you need to drink at least 5 cups a day, so it shouldn’t be considered an antioxidant.
• Carcinogens during roasting - when roasting coffee beans, benzopyrene resins appear in it, which have carcinogenic properties. The deeper the roast, the more resins. But we do not consume the grain itself, both whole and ground, and their concentration in the resulting drink is negligible. All benzopyrene remains in the cup or coffee maker, so this harm is very ephemeral, unless, of course, you drink coffee along with coffee grounds (see which products contain a lot of dangerous carcinogen - acrylamide) and why.

About instant coffee

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

Why is instant coffee not healthy?

• Firstly, instant coffee is made not from expensive Arabica, but from cheap Robusta. Coffee dust, over-roasted and substandard beans, as well as other waste from coffee production are also used as raw materials. All this is ground and processed with boiling water under high pressure. The resulting extract is filtered, dried and then sprayed in special chambers. When sprayed, drops of the extract solidify into powder. This is instant coffee.
• Secondly, most useful substances are destroyed during the manufacturing process. Therefore, to ensure necessary taste and the aroma of the drink is added to instant coffee by chicory, acorns, as well as various dyes, flavors, stabilizers, etc., and the cheaper the product, the more of them. The usual coffee content in instant coffee powder is 15%, so what about the rest?
• Thirdly, caffeine, unlike other active substances, tolerates everything very well. technological stages, so there is more of it in instant drink (80 g per cup) than in natural drink (60 mg per cup).

Why isn't decaffeinated instant coffee good for you?

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

conclusions

As can be seen from the above, the harm caused by coffee is mainly caused by excessive consumption of this drink. One or two cups of coffee a day will improve your mood and invigorate your body. But 4 or more cups a day can have a detrimental effect on your health, especially with long-term abuse. Coffee is contraindicated for people suffering from high blood pressure, heart failure, heart rhythm disturbances, as well as in case of exacerbation of gastric ulcer.

Millions of people around the world start their day with a cup of invigorating, strong coffee. Probably an indifferent person coffee beans It’s impossible to find, some are content with one morning cup of drink, while others pamper themselves throughout the day and don’t think at all about the effect coffee has on the body.

Many people sincerely believe that only a cup of very strong brewed drink helps maintain clarity of mind and think clearly. It's time to understand the effects of coffee on the body and possible side effects.

A short excursion into history

In ancient times, black coffee beans were not brewed, but rather eaten after being fried in oil. For several centuries in a row, the drink was not a drink at all, but was included in the list of expensive, gourmet dishes. The product was primarily valued for its powerful tonic and stimulating effect.

The whole world owes the appearance of this delicious drink to Arab merchants; it was they who first brought grains to Yemen. Of course, at that time no one thought about the question of whether drinking coffee was healthy, but simply enjoyed the taste and aroma. However, very soon clergy and healers began to talk about the benefits of coffee - coffee infusion helped overcome feelings of fatigue and cope with drowsiness.

A few words about caffeine

Caffeine – main component product, it is its content that determines the effect of coffee on the human body. Caffeine is an alkaloid that has a tonic effect on the nervous system. The substance is very often used as a natural, natural stimulant.

The alkaloid has a direct effect on nervous processes in the brain, increasing physical and mental activity and relieving fatigue. However, it should be borne in mind that one of its side effects is nervous exhaustion.

The effect of caffeine on each organism is individual and depends on a certain type of nervous activity of a person.

Caffeine can neutralize the effect of sleeping pills. But the opinion that the alkaloid is a drug has been partially refuted. A strong drink made from coffee beans is physically addictive, but unlike narcotic drugs, it does not cause psychological attachment.

In addition, it has been proven that with moderate consumption, the beneficial properties of coffee are revealed. Optimal daily volume strong drink– no more than two cups in the first half of the day.

What are the benefits of coffee?

• Stimulating effect

As noted above, this effect of coffee is due to the high caffeine content in the beans. The alkaloid activates blood flow, which promotes a better supply of blood and oxygen to the brain, helping a person to concentrate faster.

• Protection from stress

The grains contain the well-known hormone of happiness - serotonin, which protects against stressful situations and emotional fatigue.

• Natural Source of Antioxidants

Unlike dietary supplements obtained synthetically, coffee consumption is a natural safe way neutralize the action of dangerous oxygen radicals.

Note: two cups of natural black drink contains half daily norm antioxidants.

• Medicinal properties of coffee

Regular moderate consumption of coffee prevents the development of many dangerous diseases: diabetes, liver pathologies, Alzheimer's disease.

• The benefits of natural coffee for digestion

The drink stimulates the active secretion of gastric juice, which promotes more active absorption of food.

Health benefits of coffee - scientifically proven facts:

1. Italian scientists have found that daily use two cups of the drink prevents the development of asthma.
2. Over the course of ten years, the study, which involved more than 60 thousand people, was conducted by scientists from the Harvard College of Public Health. The conclusion is clear - if you want to protect yourself from hypertension and diabetes, drink two cups of coffee bean drink daily.
3. A drink in the diet prevents the development of urolithiasis - the formation of gallstones.

Harmful properties of coffee for the body

The beneficial properties of coffee are neutralized if you do not follow the recommended rules and abuse the drink. So, the danger is this:

• Frequent consumption of the drink negatively affects the functioning of the nervous system, the body is in an excited state, and this leads to nervous exhaustion, resulting in attacks of aggression and bad mood.
• With hypertension, tachycardia and coronary heart disease, drinking the drink leads to increased heart rate and increased blood pressure. Thus, the normal rhythm of the heart is disrupted.
• The drink can wash out some vitamins and microelements from the body, for example, B6, B1 and calcium. An insufficient amount of nutrients can provoke the development of dangerous pathologies. A lack of calcium leads to the natural destruction of bones, teeth, brittle hair, and discomfort develops in the back, which is why drinking coffee is contraindicated for children in adolescence, when the musculoskeletal system is at the stage of formation. Insufficient amounts of vitamins B6 and B1 cause disruptions in cerebral circulation. To mitigate this side effect, it is enough to use milk when brewing.
• Excessive consumption causes physical dependence, with symptoms such as fatigue, stress, drowsiness, and depressed mood. Over time, in order to achieve a tonic effect, a person has to drink more and more coffee.
• If there are disturbances in the functioning of the nervous system, drinking the drink can cause serious mental disorders and uncontrollable attacks of aggression.
• Considering that a drink made from coffee beans removes fluid from the body, having a diuretic effect, experts recommend drinking water along with it. This will help maintain normal water balance.

Contraindications to drinking black coffee

Information about coffee is quite contradictory - on the one hand, clinical studies prove the benefits of the drink, and on the other, there are specific contraindications to its use. You should not drink black coffee in the following cases:

• atherosclerosis;
• cardiac ischemia;
• kidney pathologies;
• disturbances in the functioning of the nervous system - increased excitability and insomnia;
• hypertonic disease;
• glaucoma.

The drink is also contraindicated for children and the elderly.

• Black coffee and blood pressure. With high blood pressure, coffee consumption should be minimal, this will avoid serious side effects from the cardiovascular system. vascular system. In case of hypotension - low blood pressure - the effect of coffee is regarded as medicinal, capable of improving well-being.
• Effect of coffee during pregnancy. There is no clear opinion about the benefits and harms of coffee during pregnancy. Modern medicine does not give a clear answer and takes a neutral position. It is believed that with moderate consumption side effects the drink has no effect on health expectant mother, nor on the development of the child, but it is allowed to take only a natural drink made from ground grains.

However, you should carefully dose your coffee consumption and not get carried away with the invigorating treat. Caffeine has a direct effect on the metabolic processes of calcium, and this is fraught with side effects for the unborn child. In addition, coffee has a stimulating effect on the human nervous system, and during pregnancy there is no need for excessive excitability.

Note: you should not brew the drink immediately after a meal or drink it on an empty stomach; the best time for a cup of black coffee is the first half of the day.

• A little secret: If you want to feel the most invigorating effect, just add lemon juice to your black drink. This treat has an original taste, is rich in vitamin C and has a powerful tonic effect. This is the best way to quickly and without consequences wake up in the morning, feel cheerful and overcome fatigue.
• Let's summarize. The beneficial and harmful properties of coffee appear depending on a person’s health status and lifestyle. In this case, we are talking only about natural treats made from grains. The instant drink contains too many synthetic and chemical additives that can have side effects on health. Therefore, the benefits and harms of instant coffee differ from the effect of a natural product.

In order for the benefits of natural coffee to manifest themselves in full force, it is important to know when to stop and not overuse the drink, otherwise caffeine simply will not have time to be eliminated from the body, accumulating and having a destructive effect.

Coffee lovers do not neglect a couple of cups of an invigorating drink during the day; some indulge in this pleasure even late in the evening.

More recently, excessive coffee consumption was considered very dangerous. Now the situation has changed. Recent studies have shown that most negative effects are associated not with the harmfulness of coffee, but with individual intolerance to individual components of the drink.

Nutritional value and composition

100 g of ground coffee powder contains 200.6 kcal. Since 5–6 g of powder is used to prepare a serving of the drink, the calorie content of one cup will be extremely low and will be only 10–12 kcal. Adding sugar or milk to your drink will increase the calorie content of a cup of coffee.

Coffee beans contain about 2000 components, including:

• water – 3%;
• caffeine – 0.6–2.7%;

• micro- and macroelements: potassium, calcium, magnesium, phosphorus, sodium, iron;
• organic acids – 8%;
• vitamins P, B2, thiamine.

The composition of the beans varies depending on the variety, degree of roasting and the duration of the thermal effect on the product. Roasting has a particularly strong effect on the caffeine content: its concentration increases by 1.3%.

How is it useful?

Everyone notices that after a cup of coffee, performance sharply increases, concentration and reaction speed increases, physical endurance increases and mood improves. What other beneficial properties does coffee have?

This drink has an effect on all human organ systems:

• central nervous system. Caffeine dilates blood vessels, accelerates blood circulation and stimulates brain function. It is thanks to these properties of the drink that a person’s performance and attentiveness increase, and their memory improves. Doctors note that drinking 4 cups of coffee daily reduces the risk of such terrible diseases as Alzheimer's and Parkinson's diseases by 50%.
• Musculoskeletal system. Despite the fact that caffeine contributes to the leaching of calcium from the body and the destruction of bone tissue, drinking coffee reduces the risk of gout by 40%. In addition, this drink reduces muscle pain after intense sports training. To avoid the debilitating muscle pain that invariably accompanies beginning athletes the morning after exercise, it is recommended to drink 2 servings of coffee before visiting the gym.
• Mental condition. Coffee promotes the production of serotonin, the hormone of joy, so an aromatic drink can be considered an excellent remedy from depression. It fights no less effectively against apathy, lethargy, and drowsiness. You can also drink it to combat stress.
• The cardiovascular system. Caffeine stimulates the heart, increases heart rate, dilates blood vessels and increases blood pressure. That is why, when there is a sharp drop in blood pressure, the patient is recommended to drink a cup of strong coffee.
• Respiratory system. Caffeine relaxes Airways, due to which the intensity of cough is reduced and the frequency of asthmatic attacks is reduced by 25%.
• Oral cavity. Due to the acid content and essential oils coffee has a slight antibacterial effect: it prevents the development of caries and other bacterial diseases of the oral cavity. But a dark drink will have the most negative effect on the color of tooth enamel: with regular coffee consumption, teeth turn yellow and become covered with a brown coating.
• Digestive system. Coffee effectively cleanses the body of toxins, removes harmful substances, and activates metabolic processes. That's why drinking this drink helps you lose weight. In order for sports training to give maximum results, you need to drink a cup of an invigorating drink an hour before going to the gym.

Coffee has a beneficial effect on all organs of the digestive system:

• has a laxative effect, activates intestinal function in people with difficulty digesting food;
• helps maintain the health of the gallbladder and kidneys, preventing the development of gallstones ( chemical substances contained in coffee prevent bile from thickening and crystallizing);
• reduces the risk of type 2 diabetes several times, since caffeine and chlorogenic acid prevent the accumulation of amyloid protein in the pancreas;
• reduces the rate of development of alcoholic cirrhosis of the liver;
• promotes the secretion of gastric juice, increases its acidity (coffee - great drink for people suffering from gastritis with low acidity).

In addition, daily coffee consumption reduces the risk of developing cancer. The drink prevents cancer of the liver, intestines, pancreas, prostate, mammary glands, Bladder and skin. To get the desired effect, it is enough to drink 2-4 cups of coffee every day. However large quantity drink may be harmful.

Is there any harm?

Harmful properties coffee appear in the following cases:

• excessive consumption (more than 6 cups per day);
• individual intolerance to individual components of coffee beans;
• love of espresso-based drinks (coffee with milk, cappuccino).

The latter circumstance does not always cause harm. For example, drinking coffee with milk prevents calcium from being washed out of the body and stops the destruction of bone tissue. However, the calorie content of such a drink is extremely high. If a cup of espresso contains only 10 kcal, then a serving of coffee with milk and sugar contains about 60 kcal.

Consequences of abuse of coffee-based drinks:

• Increased cholesterol levels and increased risk of cardiovascular disease. During the preparation of the drink, harmful chemical elements are released from coffee powder - caffeol, coffeestrol and benzopyrene. They increase cholesterol levels, cause tachycardia, contribute to increased blood pressure and rapid wear of the heart muscle. The amount of harmful substances depends on the roast: heavily roasted coffee contains more harmful compounds.
• Nervousness and irritability, depression and lethargy, anxiety and insomnia. The fact is that a single dose of coffee stimulates the functioning of the nervous system. If the nervous system is regularly in an excited state, severe stress occurs. Its consequence is the depletion of nerve cells and the appearance of neuroses, psychoses, and paranoid states. If a person suffers from mental illness, the ingestion of caffeine in the body will provoke unmotivated aggression.
• The emergence of addiction. People, for a long time Coffee drinkers notice that when they stop drinking for a short time, they experience headaches, irritability, drowsiness, or nausea. Without a cup of your favorite drink, a person can no longer wake up; he walks around irritated and angry all day. The symptoms are reminiscent of the withdrawal symptoms of drug addicts.
• Poor absorption of important vitamins, micro- and macroelements. Coffee reduces the absorption of B vitamins, calcium, potassium, sodium and magnesium. Moreover, coffee flushes calcium from the body and makes bones more brittle and brittle.
• Skin disease. Doctors say that daily coffee consumption contributes to rapid fading of facial skin and provokes the occurrence of skin diseases (for example, rosacea). This is due to the fact that coffee dehydrates tissues, depriving them of softness and elasticity.
• Gastritis. The ability of coffee to stimulate the production of gastric juice and increase its acidity sometimes results in serious troubles: drinking coffee on an empty stomach can provoke an attack of gastritis or the development of an ulcer.
• Dehydration. The diuretic and laxative properties of coffee often bring an unexpected result: the body may lose too much water. Paradoxically, the more coffee a person drinks, the more water he should drink daily. Avoiding dehydration is easy - just include other drinks in your diet in addition to coffee.
• Complications during pregnancy. Drinking more than 4 cups of coffee per day during pregnancy can lead to complications, as well as to health problems for the newborn baby (he will grow more slowly and have difficulty gaining weight).

A large number of people cannot imagine their morning without a fragrant cup of coffee; this tonic drink invigorates and energizes. There are many studies and opinions about coffee, the benefits and harms for the human body. Which of them are correct and is there a danger of harming your health by drinking the drink every day?

Composition of coffee beans

Coffee is made from roasted beans of the coffee tree. There are more than 90 varieties of such plants in nature. Of the industrial varieties, Arabica and Robusta are most often used.

Coffee beans contain more than one thousand different components, 800 of them are aromatic substances that give the drink a unique smell. Grains contain:

• Carbohydrates provide the body with energy and contribute to the accumulation of nutrient reserves.
• Tannins (tannins) have astringent properties, have antimicrobial, hemostatic properties, and remove toxins in case of poisoning.
• Organic acids: malic, acetic, citric, oxalic, pyruvic acids take part in the metabolic processes of the body.
• Alkaloids: caffeine, theophylline, theobromine affect the nervous system, increase body tone, performance, and concentration. Regulates the level of glucose in the blood.
• Nicotinic acid is involved in the formation of digestive enzymes, lipid metabolism, and redox processes in the body.
• Chlorogenic acid has a pronounced antioxidant effect, has antiviral, hepatoprotective (protects liver tissue), and antitumor properties.
• Macro and microelements: calcium, iron, fluorine, sodium, magnesium, phosphorus, sulfur are involved in biochemical processes.

Is drinking coffee harmful? Spanish scientists have found that the peel of coffee beans contains a large amount of antioxidants (tannins), which are much stronger than vitamin C or green tea. These substances help remove toxins from the body. In addition, the shell contains plant fiber and phenols, which stimulate the gastrointestinal tract.

During roasting, the water content in beans decreases by 3 times. The calorie content of 1 cup of tonic drink is only 9 kcal, but if you add a little milk or dilute it with cream, the energy value of the product increases to 40–60 kcal.

Beneficial features

What are the benefits of coffee for the body?

• It has diuretic properties, therefore preventing the formation of kidney stones.
• The benefits of coffee are used to prevent constipation. The plant fiber contained in grains helps with this. Caffeine increases the acidity of gastric juice and stimulates increased liver function and bile production.
• Caffeine stimulates the nervous system, increasing efficiency, tones the body and eliminates drowsiness and headaches. The effect lasts 3–4 hours.
• The benefit of coffee for the respiratory system during bronchitis and pneumonia is the removal of phlegm, due to the content of tannins. In combination with lemon and honey, it strengthens the immune system, suppresses viruses, and enhances the antioxidant effect.
• A sugar-free drink is good for female body when losing weight. It promotes fat burning during exercise due to the increased tone and performance caused by caffeine.
• Coffee is known to be beneficial for hypotension, as it increases blood pressure.
• Due to its antioxidant content, coffee is a cancer preventative in women and men. Antioxidants protect cell structure from the effects of free radicals.
• The drink prevents Parkinson's and Alzheimer's diseases due to stimulation of the central nervous system. Drinking coffee prevents the destruction of brain cells.
• What are the benefits of coffee? Caffeine enhances the effect of medications such as Aspirin and Paracetamol, increasing the load on the liver.
• The drink helps with poisoning due to its antioxidant effect. Helps remove toxins from the body.
• Caffeine, when consumed in moderation (up to 300 ml per day), restores damaged liver cells, preventing cirrhosis.

The benefits of coffee appear only with moderate use of the drink; large doses (more than 300 ml per day) contribute to addiction and intoxication of the body.

Varieties of instant drink

According to the production method, instant coffee can be powdered, sublimated or granulated. Powder is prepared from roasted and crushed grains, soluble substances are extracted from the resulting mass, cooled, filtered, and dried with hot air.

Production granular drink identical, only at the end the powder is formed into granules using steam supplied under high pressure.

The freeze-dried product is prepared differently. First, a decoction of coffee beans is made and completely frozen; the resulting mass is dehydrated under low pressure. The product is then crushed into small pieces irregular shape. The freeze-dried variety, unlike other types of instant drinks, preserves the properties and taste of natural grains as much as possible.

The beneficial and harmful properties of coffee in the form of powder or granules are manifested in lower caffeine content, so you can drink 4-5 cups every day. Harmful properties appear in case of overdose: the functioning of the heart, liver, and nervous system is disrupted. Cardiac activity, cerebral vessels, and the central nervous system are affected by increased blood circulation, and liver function is affected by increased acidity of gastric juice.

Freeze-dried coffee retains the same amount of caffeine as natural black coffee. It has the same effect on the body.

To add piquancy and variety to the popular drink, flavored varieties are produced with the taste of caramel, chocolate, vanilla, hazelnut, almond, honey, lemon, and alcoholic beverages. The flavored product in grains has become especially famous.

A refined taste is imparted by spraying flavored substances (essential oils) onto the grains, the inside of the package, and into the ground powder. What are the benefits of a flavored drink? The beneficial properties of coffee are the same as those of natural varieties. You just need to remember that a natural flavored product made from quality grains cannot be cheap.

Coffee addiction

Is coffee harmful to health? When taken correctly, the natural drink does not cause harm, and in some cases is even beneficial. Its systematic consumption of 3 cups every day can cause addiction (theism). A dosage of more than 4 cups can lead to intoxication of the body due to the effects of caffeine on the heart and central nervous system, anxiety, tremors of the limbs, confusion, and a severe headache.

Important! The safe daily dose of caffeine for humans is 300 mg. More than 90 mg of caffeine (1 cup) per 1 kg of body weight, drunk in a short period of time (2-3 hours), can lead to death. The load on the heart increases, blood circulation is impaired and death can occur!

Caffeine tones the nervous system, improves mood, and increases performance. Therefore, it causes psycho-emotional addiction. A dependent person without drinking coffee feels irritation, headache, decreased performance, and drowsiness.

Methods for preparing the drink

Freeze-dried coffee with milk: harm or benefit? When preparing the drink, it is not recommended to add sugar to it; it is better to drink it with honey. The benefit of coffee with milk or cream is that caffeine flushes calcium from the body, and milk replenishes this microelement. The drink retains all the harmful and beneficial properties of natural coffee.

When milk is added to a drink, calcium mineral salts accumulate in the kidneys and stones form.

Natural coffee, the benefits and harms of its use for women and men are manifested in an increase in the overall tone of the body. The negative effects of the drink cause disruption of the heart, liver, and nervous system. Blood circulation increases, which increases the load on the organs of the cardiovascular system. Increased stomach acidity after drinking coffee increases the load on the liver.

Flavored coffee beans are ground and brewed in a Turkish coffee pot. There is no need to dilute the drink with cream or milk so as not to spoil the taste of the additives. The freeze-dried or granulated soluble product is brewed with boiling water. You can add 2 tablespoons of milk to reduce bitterness, and honey instead of sugar.

You can add a slice of lemon to any type of coffee, this will give the drink special taste and aroma. Citrus zest, cloves, and cinnamon are also used. Drinking lemon will help replenish vitamin C, potassium, phosphorus and magnesium, which caffeine removes. Lemon has a beneficial effect on the condition of blood vessels, while neutralizing the effect of caffeine.

Coffee with lemon and honey is also useful for treatment colds, since caffeine removes phlegm, and citrus strengthens the immune system, fights viruses, and relieves inflammation. Honey is a powerful antioxidant and reduces the harm from drinking coffee.

To add to a tonic drink, it is best to use linden and buckwheat honeys; they help reduce the bitterness of natural coffee. You need to prepare a drink with honey correctly, bee product add to a warm drink (50˚), otherwise all the beneficial properties of honey disappear.

Harmful effects

What harm does coffee cause to the body?

• Due to its diuretic properties, coffee flushes calcium from the body and, at the level of brain activity, dulls the feeling of thirst. This occurs due to impaired blood circulation in the blood vessels of the brain when drinking coffee. This condition threatens dehydration.
• It is harmful to drink an instant drink (powdered, sublimated or granulated) in the morning on an empty stomach; it irritates the mucous membranes of the gastrointestinal tract, causing an exacerbation of diseases.
• Caffeine on an empty stomach creates an acidic environment in the stomach due to its chlorogenic acid content. This leads to the formation of heartburn.
• Drinking caffeine (more than 300 mg per day) is harmful. Diluting the drink with cream or milk does not reduce the caffeine level, so harmful effects drink remains the same.
• The harm of coffee is to increase appetite due to accelerated digestion of food. Therefore, when losing weight or excess weight, you need to control the amount of drink consumption.
• Coffee can cause great harm if you drink it immediately after a meal and disrupt the digestion process. A drink mixed with food has a negative effect on primary processing products with stomach enzymes.
• Coffee causes staining of tooth enamel. Carbohydrates cause the formation of persistent pigmentation on the surface of teeth.
