The article will reveal all the mysteries that coffee conceals, answer questions about the harms and benefits of coffee, how to store coffee, what are the differences between Arabica and Robusta, which coffee grind to prefer, and many others.

A drink without which many can no longer imagine their lives, coffee has not only become a fixture in the diet, but has also become an integral part of small talk and business meetings, as well as a means to boost energy, improve mood, and a salvation for people with low blood pressure.

However, from time to time you can hear about the results of another study with new facts about the harm or benefits of coffee. Should I give up this familiar drink, or is it completely harmless? In order to make an informed decision, you need to know all the pros and cons of coffee.

How does coffee affect the human body?

The effect that coffee has on the human body consists of the actions of its individual components. Therefore, first you should look into chemical composition this drink.

Raw coffee beans

Raw coffee beans contain:

• proteins, fats and carbohydrates
• alkaloids (trigonelline and caffeine)
• acids (chlorogenic, quinic, citric, caffeic, oxalic, etc.)
• tannins
• mineral salts and trace elements (potassium, phosphorus, calcium, iron, nitrogen, etc.)
• vitamins
• essential oils

When roasting, the proportions of elements contained in the grain change, and new compounds are formed (for example, vitamins PP). Depending on the type of coffee beans and the degree of roasting, the composition of the drink also differs.

• Caffeine
  Known for its arousal properties nervous system, increased productivity, increased energy, reduced physical fatigue and drowsiness. Caffeine is also accused of causing addiction and addiction.

IMPORTANT: Caffeine is found in many plants, but in large quantities - in guarana, tea leaves, coffee beans, cocoa and kola nuts.

• Trigonelline
  During the roasting process of beans, trigonelline participates in the formation of the multicomponent substance kafeol, which gives coffee its characteristic taste qualities and aroma. In addition, when fried, trigonelline releases nicotinic acid (vitamin PP or B3), which improves microcirculation, reduces cholesterol levels, etc.

IMPORTANT: A lack of vitamin PP can lead to the development of pellagra (symptoms: diarrhea, mental impairment, dermatitis).

• Chlorogenic acid
  It is present in various plants, but coffee has the highest concentration of this acid. The beneficial properties of chlorogenic acid include improving nitrogen metabolism. In addition, the acids contained in coffee help normalize the functioning of the gastrointestinal tract. Chlorogenic acid imparts an astringent flavor to coffee.

• Vitamin P
  Strengthens the walls of capillary vessels. One cup of coffee contains approximately one fifth daily requirement in this vitamin.

• Essential oils
  They have an antiseptic effect and participate in the formation of the attractive aroma of coffee.

• Tannins (tannins)
  They have a beneficial effect on digestion and give coffee a bitter aftertaste.

Harm from drinking coffee

At first glance, the components present in coffee do not cause any harm to the body. But recommendations to give up this drink are still heard quite often. This can be explained by the following negative factors:

• Addiction
  Regardless of how many cups of coffee you drink a day, you become accustomed to a certain dose of coffee, without which you already feel some discomfort. For this reason, and also because of the feeling of pleasure that coffee evokes, some people try to attribute narcotic properties to coffee. However, the release of the “happiness” hormone serotonin is also observed after eating chocolate. Obviously, classifying these products as drugs is an exaggeration. As for addiction, the unpleasant symptoms of irritability and headaches that appear when you suddenly stop drinking coffee usually disappear quickly.

• 
  Drinking coffee is often associated with a risk of heart disease, particularly coronary heart disease. There is no reliable evidence that coffee can cause coronary heart disease in a completely healthy person. However, for people suffering from cardiovascular diseases, drinking coffee, as well as other caffeine-containing products, is hazardous to health.

• Increased pressure
  Coffee can really increase arterial pressure, but this effect is short-lived. In addition, research results have shown that in most cases, people who are not accustomed to coffee react with an increase in blood pressure. For those who drank coffee on a regular basis, the increase in blood pressure was either not observed at all or was slight. Therefore, a direct relationship between coffee consumption and the development of hypertension has not been identified. It should be noted that we are talking about reasonable amounts of daily coffee consumption (see below for more details) and healthy people. Obviously, coffee is contraindicated for hypertensive patients.

• Inability to absorb calcium
  Coffee interferes with the full absorption of calcium. This is one of the reasons why drinking coffee is not recommended during pregnancy, when the female body especially needs calcium. In addition, there is no point in combining the intake of foods that serve as a source of calcium with the consumption of coffee (curds, cheeses, etc.), since calcium simply will not be absorbed by the body.

• Nervousness and irritability
  These and more serious disorders of the nervous system can be caused by excessive caffeine consumption. According to the study, drinking more than 15 cups of coffee per day can lead to hallucinations, nervousness, convulsions, fever, increased heart rate, vomiting, stomach upset, etc.
  Individual sensitivity to coffee should also be taken into account here. For some, 4 cups a day has no effect on their well-being, while others feel nervous even after one.

• Formation of benign breast tumors
  This conclusion was reached when studying the effect of excessive doses of caffeine on the female body. This applies to all caffeinated products. There is evidence that a benign tumor disappears when caffeine consumption is stopped.

• Dehydration
  One of the disadvantages of coffee is dehydration of the body, and a person does not always feel thirsty. Therefore, coffee lovers should control the amount of liquid they drink and remember the need for additional water intake.

• And etc.

Coffee should not be consumed if:

• atherosclerosis
• insomnia
• hypertension and heart disease
• glaucoma
• increased excitability
• cholecystitis
• liver cirrhosis
• diseases of the stomach (ulcers, gastritis, etc.), kidneys
• and etc.

You should not indulge in coffee before bed due to possible insomnia and increased excitability.

It is advisable to give up coffee or reduce its amount during pregnancy. This warning was initially explained by the threat of miscarriage. Recent studies say that caffeine abuse affects the weight of the fetus, as well as the duration of pregnancy. Caffeine reduces baby's birth weight and prolongs gestation period.

In general, it is advisable to talk about the dangers of coffee under the condition of significant abuse, when purchasing low-quality, cheap coffee, as well as in case of violation of the rules for preparing this drink.

Benefits of drinking coffee

Reasonable consumption of caffeine not only does not harm, but also has a positive effect on the functioning of the body. In particular, coffee:

• promotes mental activity of the brain
• tones, improves mood, adds strength and energy
• eliminates headache, migraine
• relieves fatigue, lethargy, drowsiness
• is an antidepressant, reduces the likelihood of suicidal episodes

• stimulates memory and prevents Parkinson's and Alzheimer's diseases
• weakens the effect of hypnotic substances, caffeine is used for intoxication with poisons and drugs
• stimulates the stomach
• increases heart activity, increases blood pressure, which alleviates the condition of hypotensive patients
• has anticarcinogenic properties, reduces the risk of developing cancer
• reduces the likelihood of liver cirrhosis, gout, diabetes, kidney problems

It is important to emphasize that the positive effect of coffee consumption can only be achieved with moderate consumption of this drink.

Daily coffee consumption

You can allow yourself 300-500 mg of caffeine per day without harm to your health. Depending on the degree of roast and variety, one mug of coffee contains 80-120 mg of caffeine. This means that approximately you can drink 3-4 cups per day without worrying about the possible consequences.

The permissible daily dose of caffeine during pregnancy, according to WHO, is 200-300 mg, which is equivalent to 2-3 mugs of coffee.

However, remember that coffee is not the only source of caffeine, so calculate your individual servings based on other caffeine-containing products you consume.

Some studies have documented the negative effects of coffee even when the daily volume of 4-5 mugs is regularly exceeded.
A daily dose of 10 g of caffeine is considered lethal, which corresponds to approximately 100 cups of coffee.

INTERESTING: In terms of the amount of coffee consumed per capita, Finland is in first place, the USA is in second, the UK is in third and Russia is in fourth place.

Types and varieties of coffee: Arabica and Robusta

There are two most popular types of coffee: Arabica and Robusta, while there are more than a hundred varieties.

Arabica

• the most common type of coffee
• has a milder taste, slight sourness and strong aroma
• contains about 18% oils and 1-1.5% caffeine

Robusta

• characterized by a coarser aftertaste and astringent aftertaste
• contains about 9% oils and up to 3% caffeine
• often used in the preparation of instant coffee
• usually due to the bitter taste in pure form not consumed, but mixed with Arabica in different proportions
• inferior in popularity to Arabica due to its specific taste
• The caffeine content of Robusta is twice that of Arabica

In addition to these types, there are also Liberica and Excelsa coffees, which are similar in taste to Robusta and are used to create blends.
The taste, smell and chemical composition of coffee, including the amount of caffeine, is determined by the climate, the soil of the coffee trees and other factors, the diversity of which determines the presence of a large number of coffee varieties.

Some of them:

• Santos, Victoria, Conilon (Brazil)
• Colombia
• Ethiopian Arabica Harar
• Arabica Mysore (India)
• Tapanchula, Maragogip (Mexico)
• Mandeling, Lintong (Indonesia)
• Arabien Mocha (Yemen)
• Nicaragua Maragojit et al.

What grind is coffee?

Depending on the method of preparation, duration of aroma development and taste, use different types grinding Highlight:

Rude

• Application: Best suited for use in French presses, piston infusers or classic coffee pots.
• Time required for full manifestation of taste: up to 8-9 minutes

Average

• Application: the most versatile grind, used for different brewing methods, good for carob coffee makers
• Time: up to 6 minutes

Thin

• Application: making coffee in a coffee maker
• Time: up to 4 minutes

IMPORTANT: There is a special grind type for espresso, which is marked accordingly on the coffee packaging. Expresso coffee machines are immediately equipped with a special coffee grinder to obtain a special grind.

Very fine (powdery)

• Application: ideal for cooking in a Turk to obtain so-called Turkish coffee
• Time: 1 minute

Grinding too fine may cause bitterness if too fine. coarse The coffee may turn out watery because if prepared incorrectly, it will not have time to develop its flavor. In addition, ultra-fine coffee as well as very coarse grinds can clog the coffee machine. Therefore, it is important to adjust the grinding well, to find the most suitable individual taste depending on the type of preparation.

You can grind the coffee yourself using a coffee grinder (manual or electric) or buy the required grind, obtained industrially. The latter usually undergoes additional filtration (through a special sieve) to select coffee particles of the same size. It is known that homogeneous coffee exhibits its taste properties better.

How long can you store ground coffee?

Coffee is very sensitive to air and light. Therefore, it should be stored in an airtight container in a cool place.

After opening the package, ground coffee It loses its original aroma and taste within a week. Accordingly, to maximize the preservation of taste, ground coffee must be kept in a vacuum.

The most popular coffee drinks

Combining many various ingredients with coffee in various proportions, you get a wide range of coffee drinks. Ice cream, caramel, milk, chocolate, liqueur, honey, berry syrups, etc. - This is an incomplete list of products compatible with coffee that give it a unique taste and smell.

Among the most common coffee drinks:

• espresso− pure coffee, which is prepared in small volumes with a high concentration of coffee, which makes the drink very strong; is the basis for preparing other types of coffee drinks
• Americano− this is an espresso with a high water content for those who do not like the bitterness of strong espresso
• cappuccino− coffee with added milk and formation of milk foam
• macchiato− subtype of cappuccino: coffee + milk foam in equal proportions
• latte– milk with coffee, where milk takes up a large share of the drink
• glasse− coffee with ice cream
• Irish− coffee with alcohol
• mocha− latte with chocolate
• Viennese coffee− espresso with whipped cream, sprinkled with chocolate, cinnamon, nutmeg, etc.
• Romano− espresso with lemon zest
• Turkish coffee− with foam with added spices (cinnamon, cardamom, etc.), classic coffee is brewed in a Turk
• and many others

Is coffee with milk beneficial or harmful?

Milk suppresses the effect of caffeine, so coffee with milk has a less tonic effect. For people suffering from gastritis or other diseases for which it is not recommended to indulge in caffeine, coffee with milk
in limited quantities it can be a great solution.

IMPORTANT: In its pure form, coffee does not contain calories, but with the addition of milk it loses its properties as a dietary product.

Is coffee with lemon good or bad?

Rich in vitamin C, lemon is undoubtedly useful product. In addition, lemon also neutralizes the effects of caffeine. When combined with lemon, the coffee drink acquires a special taste and is perfect for those who love coffee but are wary of excessive caffeine exposure.

Is coffee with cinnamon beneficial or harmful?

Cinnamon is known for its numerous healing properties and widespread use for weight loss. Therefore, coffee with cinnamon (without sugar) can become not only delicious drink, but will also contribute to weight loss (subject to other necessary conditions).
However, cinnamon, especially in large quantities, has a number of contraindications:

• pregnancy, hypertension, liver and kidney problems, increased excitability, individual intolerance, etc.

Is decaffeinated coffee good or bad?

At first glance, decaffeinated coffee solves all the problems associated with the negative consequences of excessive caffeine consumption. However, everything is not so simple.

• Firstly, This coffee still contains caffeine, but in small quantities.
• Secondly, The overwhelming majority of the decaffeination process involves treating the beans with a chemical solvent, ethyl acetate, which, despite subsequent cleaning with boiling water, risks remaining on the coffee bean.
• Third, One of the negative consequences of drinking decaffeinated coffee is an increase in the amount of free fatty acids in the blood, which are responsible for the formation of bad cholesterol.

Additionally, caffeine, as mentioned, has, when taken correctly, positive influence on the body.

IMPORTANT: According to research, the accusation that caffeine increases blood pressure is unfounded. Perhaps other components of coffee are to blame.

Therefore, drinking decaffeinated coffee is not always a reasonable substitute.

How to make coffee correctly?

The final properties of coffee, including its benefits or harm, depend on the method and correctness of preparation.

In order to cook good coffee at home, if you don’t have a special coffee machine, you need to:

• pour coffee into the Turk

IMPORTANT: It is better to give preference to the finest grind of coffee.

• pour cold water
• wait for the foam to rise and remove from heat
• let it sit a little and repeat the procedure two more times
• Before pouring coffee into cups, the latter should be heated by pouring boiling water over them.

IMPORTANT: Coffee should not be brought to a boil.

To prepare Turkish coffee, use 10 g (3 tsp) per glass of water, but the dosage can be changed based on preference.

• In order to check the quality of coffee beans, you can fill them with cold water, shake them a little and drain the water. If the color of the water has not changed, it means the coffee is of high quality, i.e. does not contain dyes
• A test for the presence of impurities in ground coffee can be carried out in a similar way: pour cool water. If impurities are present, they will settle and you will notice them at the bottom of the container.

To summarize, we list 10 Key Facts Things you need to know about coffee:

1. With moderate consumption (no more than 3-4 cups per day), coffee does not harm a healthy person
2. Moreover, coffee has a number of beneficial properties, including stimulating brain activity, suppressing depression, and preventing the development of many diseases.
3. Contraindications to drinking coffee exist if you have problems with the heart, nervous system and other diseases of the liver, kidneys, etc.
4. Arabica contains half as much caffeine as Robusta

5. Coffee grinding matters different ways making coffee. For example, the finest grind is used to make Turkish coffee and requires less time to develop its taste than a coarser grind.
6. The amount of caffeine increases with heat treatment, i.e. darkly roasted beans contain less caffeine than lightly roasted beans
7. Instant coffee is made from cheaper, less valuable coffees and contains more caffeine

8. It is preferable to buy coffee beans and grind it before preparing it, since ground coffee quickly loses its aroma and original taste characteristics, and it cannot be stored for a long time without vacuum packaging.
9. Decaffeinated coffee may even be harmful if decaffeinated using certain methods.
10. It is recommended to drink coffee in the morning, but not on an empty stomach, as it stimulates digestion

Video: Scientific news about the benefits of coffee

The benefits of coffee are not the only factor why most people start the day with this drink and cannot imagine life without a cup of coffee in the morning. The popularity of the drink is due not only to its taste, but also to its specific composition, which allows you to awaken and improve your performance. Numerous disputes about the benefits and harms of coffee arise due to stereotypical thinking about drug addiction, which is allegedly caused by caffeine, which is part of coffee. Thus, more and more people are abandoning the natural product, preferring an artificial caffeine-free substitute.

Despite all the arguments of opponents of coffee, its effect on the human body is individual. Caffeine stimulates the nerve endings of the brain root, which provokes a surge of energy and stimulates mental activity. The effectiveness of caffeine is determined by the type of higher nervous system. Based on this, it is important to choose a dosage that is individually suitable for the body. In old age, coffee can cause a jump in blood pressure, but only if it is abused.

The desire for a caffeine fix is ​​somewhat addictive. Systematic and long-term use coffee may promote the appearance of adenosine receptors. They neutralize the effects of caffeine, but at the same time create a feeling of chronic fatigue and drowsiness. However, the benefits of coffee have long been used in medicinal purposes and helps restore the health of the central nervous system and cardiovascular system.

Composition of grains

Everyone knows that the harm and benefit of coffee lies in the caffeine it contains. In addition to caffeine, the beans contain many active components, the chemical reactions of which occur during the roasting process. The composition is also responsible for the taste of the drink. Fresh grains contain alkaloid substances, protein, amino acid and lipid substances, organic acids and polysaccharides. After roasting, chemical compounds are formed in the beans:

• protein substances;
• carbohydrates;
• cellulose;
• glucose;
• fructose;
• tannin;
• caffeine;
• pectin substances.

The grains also contain vitamins B, PP, K and trace elements: calcium, magnesium, iron. The caffeine content depends on the roasting of the beans: the more insignificant it is, the less it is formed. The flavor of coffee is created by chlorogenic acid during the process. heat treatment. Essential oils and tannin give the drink its aroma.

What are the health benefits of coffee?

The benefit of coffee lies in its effect on the nervous system. Caffeine stimulates brain function, heart function and blood circulation, improves attention and improves mood. Caffeine is a psychostimulant and stimulates the production of the hormone serotonin, which suppresses depression and improves well-being.

Everything you need to know about coffee

Speaking about the benefits of coffee, it should be mentioned that it creates resistance to stress and increases mental activity. Coffee is beneficial for the body because it:

1. Prevents the development of cancer.
2. Prevents the development of Parkinson's disease.
3. Prevents diabetes.
4. Prevents diseases of the reproductive system.
5. Promotes weight loss.
6. Stimulates digestion.
7. Prevents the development of Alzheimer's disease.
8. Reduces the risk of heart attack.

Moderate consumption of the drink stimulates the functioning of the cardiovascular system and eliminates the likelihood of developing coronary diseases. It is also useful to drink the drink as a preventive measure for heart disease, since the chemical composition of the grains includes components that strengthen the walls of blood vessels and reduce the risk of blood clots. It removes waste and toxins from the body and prevents the accumulation of cholesterol.

Healthy to drink no more than 2 cups coffee drink. You can increase the dose in case of migraine, since caffeine consumption helps to dilate blood vessels, relieve pain and spasms.

Benefit natural coffee is important for men, because coffee is an aphrodisiac and stimulates potency. This also increases sperm motility. It is also beneficial for the body in case of digestive disorders, as it stimulates natural peristalsis and promotes absorption. useful substances in the intestines. Caffeine is used as an active substance in medicines.

What is the harm of coffee to the body?

The most common theory about the dangers of coffee is that it is addictive. Physical dependence is an individual factor that can be identified by characteristic symptoms if you stop using it for a while.

You should not get used to coffee, as symptoms of fatigue appear during the period of coffee abstinence.

During the period of coffee withdrawal, symptoms of fatigue, irritability, apathy, nausea, depression, depression and muscle pain appear. The drink has a tonic and stimulating effect on the central nervous system, therefore, increasing the dose of consumption increases the addiction. This effect is a consequence of excessive caffeine consumption, so if you do not have such a habit, there is nothing to fear.

What are the benefits of green onions?

However, there are also contraindications to drinking the drink. Coffee negatively affects the health of the nervous system. Being in a state of excitement for a long time, the central nervous system experiences stress, which depletes nerve cells and contributes to disruption of the functionality of the nervous system. He also bad for mental health. Excessive coffee consumption can cause the development of mental illness and mental disorders. Caffeine irritates nerve cells and encourages unmotivated aggression, irritability and temper.

An important factor in which the consumption of the drink is prohibited is diseases of the cardiovascular system. This is due to the fact that caffeine stimulates cardiac activity and increases the pulse rate. This causes a jump in blood pressure. With ischemic diseases, the risk of a heart attack increases.

Impaired heart function also affects healthy people. Excessive consumption of coffee drinks can cause the development of pathologies. This does not mean that if you systematically drink 2 cups of coffee, your health will certainly be harmed. Caffeine only increases the risk of developing ischemic diseases, which can occur against the background of other factors. But coffee really makes it difficult to absorb vitamins and leaches microelements from the body. This leads to fragility of bones and blood vessels. It is not recommended for pregnant women to consume the drink, since coffee:

• increases the risk of miscarriage;
• makes breastfeeding difficult;
• promotes the development of cellulite;
• reduces skin elasticity before stretch marks;
• stimulates the development of fetal nervous pathologies.

The dangers of decaffeinated coffee

Caffeine is removed from beans by decaffeination. This process consists of pouring hot water coffee beans to flush out the caffeine from their contents. The beans soften, making it easier to remove caffeine from them. There are several methods of decaffeination:

• Solvent. For this purpose, the chemicals methylene chloride or ethyl acetate are used, which neutralize caffeine. Excessive intake of these substances into the body provokes addiction, similar to drugs.
• By water. This is absolutely safe way neutralizing caffeine, which washes it out of the beans, while maintaining their taste properties. It is safe for health, but expensive in terms of financial resources.
• Gas. To remove caffeine, compressed gas is used, which displaces the substance from the beans and does not affect their chemical composition.

Cosmetic uses of coffee

Such scrubs are made from natural ground grains and are used to prevent aging, to cleanse the skin of blackheads and against cellulite. Coffee oils are also used in cosmetology to nourish hair. The use of coffee is also reflected in the fight against excess weight. It is considered an excellent fat burner. Green grains are used for this. They are not fried, but dried, ground and brewed as usual. Drinking this drink reduces appetite, helps cleanse the body of waste and toxins and improves skin condition. Before you start consuming green grains, you should consult a specialist to ensure there are no contraindications.

We can talk endlessly about the benefits and negative effects of coffee. It is impossible to say unequivocally: it is useful or vice versa. It's important to remember that By consuming it in moderation, you do not cause any harm to the body. You need to set the dose of the drink, and then nothing will threaten your health.

It's hard to find another product that causes as much controversy as coffee. Articles appear in the media with enviable regularity that talk about the results of new studies that have proven the harmlessness or even usefulness of coffee. How much can you trust such research? And what should we do about studies that prove coffee is harmful?

In this article I do not pretend to be absolutely objective - I myself gave up coffee several years ago, having experienced a rather unpleasant 2 weeks of “withdrawal”. But this was my personal decision, and now I want to consider all the arguments for and against. Perhaps for some, the arguments in favor of coffee will outweigh the arguments against it.

What is coffee? Why are many people so attached to this drink and cannot imagine how to wake up without coffee in the morning? What is the effect of coffee based on?

Caffeine is a psychostimulant and has a stimulating effect on the nervous system. Under the influence of caffeine, cardiac activity accelerates and blood pressure rises. Caffeine enhances and regulates excitation processes in the cerebral cortex; in appropriate doses, it enhances positive conditioned reflexes and increases motor activity. The stimulating effect leads to increased mental and physical performance, reduced fatigue and drowsiness.

The effects of caffeine last for several hours. Then fatigue sets in.

Systematic consumption of caffeine in large doses (1000 mg per day or more) causes depletion of nerve cells. Over time, addiction develops.

In very large doses (approximately 10 grams) it causes death.

All of the above does not indicate either the harm or benefit of coffee, but clearly indicates that coffee actively affects the human body and is by no means a neutral product. So, can coffee have health benefits and when? Does regular consumption of this drink cause harm and what kind of harm? And finally, what outweighs - harm or benefit of coffee?

Let's analyze the arguments for and against coffee and draw our own conclusions.

Harm from coffee.

Coffee is physically addictive.

To determine whether you are addicted to caffeine or not, you need to stop drinking coffee and other caffeinated drinks for a while. If you have an addiction, you will experience symptoms such as:

• headache,
• fatigue and drowsiness,
• irritability,
• worsening mood, from mild depression to depression,
• nausea,
• muscle pain.

All or some of the above symptoms may appear.

With addiction, the tonic effect of coffee gradually decreases and an increasingly larger dose is required to achieve the same effect. The larger the dose, the stronger the addiction, the greater the harm of coffee and the more difficult it is to give it up.

Harm of coffee to the nervous system.

With prolonged stimulation of the nervous system, the body is constantly in an excited state. The nervous system experiences prolonged systematic stress. This stress causes depletion of nerve cells and disrupts the normal functioning of all body systems.

The harm of coffee to mental health.

Drinking caffeine in large quantities can lead to the development of various psychoses, epilepsy, and paranoia. May cause unmotivated aggression.

Coffee is harmful to the heart.

Coffee increases cardiac activity, stimulates the vasomotor center, and increases the pulse rate. Caffeine has a short-term effect on blood pressure - leading to a slight increase in blood pressure. The above properties of coffee make it especially harmful for people with diseases of the cardiovascular system (arterial hypertension, coronary heart disease, etc.). But coffee can also harm the cardiovascular system of healthy people. The greater the amount of coffee consumed, the higher the risk.

The harm of coffee to the cardiovascular system depends on the following factors:

• Presence of diseases of the cardiovascular system.
• Hereditary predisposition to diseases of the cardiovascular system.
• Other factors that contribute to such diseases (weight, diet, physical activity).
• Amount of coffee consumed.
• Method of preparing the drink: Coffee prepared by brewing is much more harmful to the heart than coffee prepared in a coffee maker.

Coffee interferes with absorption and leaches important microelements from the body.

Caffeine washes out some important microelements and interferes with their absorption. These are the following microelements:

• potassium,
• sodium,
• vitamins B1 and B6.

This leads to many serious problems:

• Due to a lack of calcium, teeth deteriorate, bones become brittle, and osteochondrosis may develop. perfectly flushes calcium from the body.
• An imbalance in the calcium-magnesium system leads to chronic pain in the back and cervical spine.
• A lack of vitamins B1 and B6 leads to problems with blood supply to the brain. Symptoms are headache and irritability.

Harm of coffee for children and pregnant women.

Drinking coffee during pregnancy increases the risk of fetal death in the womb (about 4 cups of coffee per day increases the risk by up to 33%) and causes harm to fetal development:

• The baby is often born with a low birth weight.
• Teeth start cutting later than they should.
• The child's height is lower than that of his peers.
• A child is born with a caffeine addiction.

Consumption of products containing caffeine (and this is not only coffee, but also chocolate, cocoa, etc.) causes enormous harm to children's health. Harm of coffee for children can lead to problems such as:

• enuresis (bedwetting),
• nervous tics (involuntary constant muscle contractions, twitching),
• mood swings, tearfulness, aggressiveness and other inappropriate behavioral reactions,
• fears, anxiety.

In addition, everything that was said about adults is relevant for children. The only difference is that a much smaller dose of caffeine is enough to harm a child’s body.

The dangers of decaffeinated coffee.

The health risks of coffee mentioned above are associated specifically with caffeine. The main argument against decaffeinated coffee is that its production uses far from harmless chemicals. Is this really true? There are several ways to remove caffeine from coffee beans (decaffeination):

1. The “traditional” method, in which the solvent methylene chloride (methylene chloride - dichloromethane, methylene chloride - a colorless liquid with a chloroform odor, which has a narcotic effect) or ethyl acetate (a colorless liquid with a fruity odor) is used to remove caffeine. Recently, ethyl acetate has been mainly used. After the caffeine is separated, some solvent remains in the beans. The solvent may be harmful to health.
2. The "water only" method of decaffeination does not use any chemicals. This method is more expensive, but coffee is obtained without chemical additives, while maintaining its taste and aroma.
3. Another method of decaffeination is to use compressed gas (carbon dioxide CO 2). Carbon dioxide leaves no traces in the drink and disrupts its taste and aroma.

Thus, only the “traditional” method of decaffeination adds harmful chemicals to coffee. But it is worth keeping in mind that decaf coffee still contains caffeine, although in smaller doses than regular coffee. For example, 10 cups of instant coffee that says “decaffeinated” on the can contains the same amount of caffeine as two cups of regular coffee.

In addition, decaffeinated coffee negatively affects the cardiovascular system and promotes fat storage. This type of coffee increases the level of bad cholesterol in the blood, which in large quantities leads to serious arterial diseases.

The benefits of coffee.

Often, as an argument in favor of coffee, they talk about its invigorating and stimulating effect. In my opinion, this property of coffee cannot be called beneficial to health. As stated at the beginning of the article, caffeine is a psychostimulant and stimulates the nervous system. To which harmful consequences leads to this effect, it is said.

There are many studies showing the health benefits of coffee. The question is, which ones should you trust? This question is especially relevant for studies whose results contradict other studies. For example, some studies report that coffee causes coronary heart disease, while others report that it does not. Obviously, the results of one study are correct and the results of the other are incorrect. I can't do my own research, so I'll play it safe and assume that coffee can still harm the heart. So, I will not include in the list of beneficial properties of coffee something that obviously contradicts the results of other studies or common sense.

Now let's talk about those arguments in favor of coffee that do not contradict the arguments against it:

The benefits of coffee in preventing cancer.

Approximately two cups of coffee per day reduces the risk of the following types of cancer:

• liver cancer,
• pancreatic cancer,
• colon cancer,
• rectal cancer.

The benefits of coffee in the prevention of Parkinson's disease.

Coffee reduces the risk of developing Parkinson's disease. Moreover, to prevent this disease, it is enough for women to drink coffee in moderate quantities, while men require large doses to achieve the same effect.

Benefits of coffee in preventing diabetes.

Coffee can prevent diabetes. To reduce the risk of diabetes by 50%, men should drink about 6 cups of coffee. Women will get a slightly smaller effect from 6 cups of coffee - the risk of diabetes will decrease by a third.

The benefits of coffee for the prevention of other diseases.

Some studies show that coffee reduces the risk of developing diseases such as:

• asthma,
• cholelithiasis,
• cirrhosis of the liver,
• heart attack,
• atherosclerosis,
• hypertension,
• hypercholesterolemia,
• migraine.

The benefits of coffee for male reproductive function.

This is not about improving potency, but only about improving the reproductive function of men - sperm motility increases.

The benefits of coffee for weight loss.

The stimulant effect of caffeine helps you lose weight overweight. 1 cup of coffee makes aerobic exercise one third more effective than usual in “burning” calories. When dieting and exercising, coffee forces the body to use fat rather than carbohydrates for energy.

Benefits of coffee for digestion.

Coffee and caffeinated drinks (for example, Coca-Cola) are often used for digestive problems and indigestion.

It is believed that coffee helps digest food, for which you need to drink a cup of this drink after lunch. True, the question arises here - what to do with mineral substances, the absorption of which coffee interferes with? Apparently, helping to digest food is not about helping the body absorb nutrients. It's not entirely clear what the benefit is.

Medical benefits of coffee.

Here we are, of course, not talking about the drink itself, but about caffeine. In medicine, caffeine is used:

• for diseases that depress the central nervous system (for example, poisoning with drugs and poisons)
• for infectious diseases,
• in case of insufficiency of the cardiovascular system,
• with vascular spasms.

Caffeine is an ingredient in some medications. In this case, we are talking about the treatment of existing diseases. These medications have their own side effects.

In general, the use of caffeine in medicine cannot be considered a beneficial property of coffee as a drink for healthy people.

Is coffee harmful or beneficial?

The above arguments for and against coffee, upon closer examination, are not so contradictory to each other. In certain cases, the obvious disadvantages of coffee can be compensated for by its beneficial properties. Everyone can decide whether they should drink coffee based on their own health. In general, coffee should be treated like a drug (which is what caffeine is). Like any medicine, it can help with certain diseases, but there are many side effects. In my opinion, coffee is more likely to do harm than good to a healthy person.

To prevent diseases, it is suggested to drink fairly large doses of coffee (for example, to reduce the risk of diabetes, you need to drink 6 cups of this drink). At the same time, there are other ways to prevent these diseases, such as

Etc.)

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 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 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 beans in a cezve or coffee maker. coffee tree. 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: 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).

About the effect on the digestive system

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

There is evidence that regular coffee consumption reduces the risk 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. 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 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 or 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 (an increase in the number of heart beats per minute above normal). For the young healthy body this is not scary, and is 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:

• In case of hypertension - provoke.
• – significant deterioration of the condition due to an increase in the need of the heart muscle for oxygen.
• – cause a heart attack up to 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, unexpected death of cardiac etiology that occurs 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, fatal blockage of an important blood 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 developing or, 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 can help reduce some allergies because it reduces the formation of histamine in the body (see)

Interesting fact: research has shown that the best release of antioxidants and caffeine is obtained when brewing coffee at room temperature (see).

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.
• Abuse of coffee increases the levels of total and LDL cholesterol (“”) in the blood, which contributes to the progression of

About false accusations and unjustified hopes

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

• 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 frying— 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 with coffee grounds(cm. ).

About instant coffee

Natural coffee cannot be instant, no matter what advertising tells 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, in order to ensure the necessary taste and aroma of the drink, acorns are added to instant coffee, 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 all technological stages well, so there is more of it in instant drinks (80 g per cup) than in natural drinks (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 heart failure, heart rhythm disturbances, as well as in case of exacerbation of gastric ulcer.

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 aromatics, which 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, 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 skin 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 energy value 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.
• Benefits of coffee for respiratory system for bronchitis and pneumonia, it involves removing mucus 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.

The production of a granulated drink is 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, irregularly shaped pieces. 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. Freeze-dried or granular instant product brew 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 in the treatment of 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; the bee product is added to a warm drink (50˚), otherwise all the beneficial properties of honey are lost.

Harmful effects

What harm does coffee cause to the body?

Harm to women's health

How is coffee harmful for pregnant women? The drink dilates blood vessels and can increase blood pressure. This is dangerous for the health of the expectant mother, as involuntary abortion, bleeding or premature birth may occur. A dangerous dosage is more than 2 cups every day. If there are disturbances in the functioning of the heart and vascular system in the expectant mother, children may be born with underweight and anemia.

The harm of coffee for young women is to reduce the possibility of conceiving a child by 40%. This happens because caffeine changes hormonal levels and negatively affects ovulation and contractility of the fallopian tubes.

For pregnant and lactating women, the harm of coffee lies in the negative impact of caffeine on the baby’s nervous system. Due to the diuretic properties, calcium is washed out, the child’s baby teeth will quickly deteriorate, and the mother will lose her permanent ones.

Important! With frequent coffee consumption, women need to replenish fluid loss in the body. You should drink at least 2 liters per day of pure still water every day.

Systematic use of a soluble freeze-dried product without constant physical activity leads to the formation of cellulite in women on the thighs and abdomen. The drink disrupts blood flow and contributes to impaired water metabolism, and these are the main reasons for the formation of “orange peel.”

Harm to men's health

What is the harm of coffee for men? When drinking a flavored drink, the level of testosterone in the blood of representatives of the stronger sex decreases. Microelements necessary for the functioning of the prostate gland (magnesium, zinc, vitamins A, E) are excreted in the urine, and sexual desire decreases.

Caffeine stimulates the production of the stress hormone and the release of adrenaline into the blood. The male body perceives this as a decrease in the need for testosterone.

The harm of coffee for the male body lies in the risk of developing enuresis (urinary incontinence). American scientists have found that drinking 3 cups of natural drink per day increases the likelihood of developing urinary incontinence by 70%.

When not to drink coffee

• Coffee is contraindicated for osteoporosis (decreased bone density, increased bone fragility) in older people, especially women, since the drink leaches calcium, phosphorus and magnesium, which are necessary for strengthening bones.
• For diseases of the nervous system, since caffeine increases the excitability of the brain.
• Heart pathologies: tachycardia, arrhythmia. The drink dilates blood vessels and disrupts heart rhythm.
• Children and teenagers should not drink this tonic drink, as coffee removes calcium, which the child’s body needs for normal growth.

In case of overdose, the harm of coffee manifests itself in the occurrence of insomnia, nausea, vomiting, and dizziness. The central nervous system is excited, and tremors of the limbs, confusion, and migraine may appear. The heartbeat increases, the rhythm of its work is disrupted, and blood pressure rises.
