Coffee is a drink that is loved all over the world! Real coffee lovers, ready to drink it in the morning, afternoon and evening! But is not such a passion capable of becoming detrimental to our health? People have been looking for the answer to this question since the advent of coffee. While some argue that it is absolutely harmless, and moreover, beneficial for our body, others are categorically against the use of this drink. The true seed is in both positions. About the benefits of coffee. It's time to look at the other side of the coin.

Ivan Pavlov is a name that is not only widely known in narrow circles, but is known to any layman. However, not everyone knows that it was he who was one of the first to study the properties of coffee. His research showed that excessive (!) Consumption of this drink can cause:

  • nervous exhaustion;
  • malfunctions of the digestive tract;
  • dependencies;
  • malfunctions of the cardiovascular system;
  • dehydration;
  • deterioration of the condition of nails, skin, hair.

Nervous system

  • Coffee is the best way to wake up! To do this, it is not necessary to pour the boiling drink on your feet, it is enough to take a couple of sips, and sleep will take off like a hand! Thus, coffee "awakens" the nervous system makes our brain work and "give birth" to bright thoughts. It would seem, what is the harm if coffee has such a stimulating effect? The fact is that with frequent use, addiction arises, due to which we can no longer "wake up" and cheer up without coffee. This, in turn, leads to nervous exhaustion, irritability, lethargy, lethargy, nervousness and anxiety. However, this does not mean that we should completely give up coffee. You just need to find the right dose.

Heart and blood vessels

  • We know very well that everything in the body is interconnected. So, coffee makes not only our nervous system work more actively, but also our heart. After a cup of this drink, it begins to pound faster, the blood increases the speed of movement through the vessels, the pulse rises. That is why coffee is not recommended for hypertensive patients, as well as for people with coronary artery disease and other diseases of the heart and blood vessels. As a result of drinking this drink, the pressure rises, which is completely contraindicated in the presence of such diseases.

    By the way, excessive consumption of coffee can also cause disturbances in the work of the cardiovascular system. At the same time, it is easy to deduce a direct relationship: the stronger the drink, the higher the risk of earning "heart" problems.

Gastrointestinal tract

  • Coffee contains substances that increase acidity. This, in turn, can cause ulcers, liver and pancreatic diseases. However, such consequences can be prevented. First, remember that this property is inherent primarily in instant drinks. That is why use natural coffee. Secondly, never drink coffee on an empty stomach! It should be drunk after a snack or food intake.

Genitourinary system

  • Among the negative consequences that can be caused by drinking coffee, we have indicated "dehydration". This is indeed the case. This is because coffee, like tea, for example, has diuretic effects. Remember coffee does not compensate for water! On the contrary: the more coffee you drink, the more water should be consumed, thereby replenishing the lost liquid. For the same reason, coffee is not recommended for people with kidney and urinary tract diseases.

Oncology

  • Fortunately, most doctors today do not consider coffee to be the cause of cancer and tumors. However, over the years, this myth has been widespread enough both in our country and abroad. Many studies on this drink have proven that coffee has anti-cancer and anti-mutagenic properties and triggers the destruction of cancer cells. This miraculous effect is explained by the fact that the fruits of the coffee tree contain a large amount of polyphenols, which have anti-inflammatory and antioxidant properties. There are several times more of these substances in coffee than in any kind of tea, juice or wine. Therefore, doctors recommend using this drink for skin cancer and even using it as an alternative to sunscreen. In addition, coffee is believed to reduce the risk of bowel cancer.

    Among other things, coffee is a "happiness" drink because it contains serotonin. In the case of cancer patients, this fact is of great importance, because a breakdown and depressive mood are frequent companions of such diseases.

Appearance

  • Despite the fact that coffee is actively used in cosmetology as a basis for masks and scrubs, experts believe that its use can lead to premature aging. This is primarily due to its dehydrating properties, as nourishment and hydration are very important for our skin.

    In addition, vasodilatation, which is also caused by drinking coffee, can cause a "mesh" on the face, bursting capillaries and redness. It's hardly worth talking about the effect of coffee on tooth enamel: like any coloring product, coffee can cause yellowness and plaque formation.

Harm of coffee for pregnancy

  • The harm of coffee for expectant mothers has been scientifically proven. If a pregnant woman drinks at least 4 cups of coffee a day, then the risk of termination of pregnancy is more than 30 percent. But as soon as she reduces her coffee consumption to 3 cups, the percentage of risk drops rapidly. Especially coffee has a harmful effect on gestational age from 20 weeks.

Harm of coffee for the content of trace elements in the body

  • Another "disadvantage" of coffee is that it interferes with the assimilation of a number of trace elements and vitamins, including, for example, calcium, magnesium, sodium. This is fraught with the occurrence of osteoporosis, which should be feared primarily by women. In order to prevent the disease and replenish the loss of trace elements, coffee lovers need to periodically drink vitamin-containing complexes.

Influence on the body

  • The main negative factor in the constant use of coffee is the emergence of addiction. We talked about this earlier. Coffee actually becomes a drug, and the person has to increase the dose all the time. However, if you decide to get rid of this addiction, do not make "sudden movements", reduce the amount of drink and its strength gradually.

Well, if you can't refuse coffee, then pay attention to our useful tips!

"Among other things, coffee is a drink of" happiness "because it CONTAINS serotonin" - wow! I, naive, thought that serotonin is a hormone produced by the brain, and it turns out that it is "contained" in coffee. Powerful.

Many modern people can no longer imagine their life without coffee. An invigorating drink helps to wake up in the morning, raises blood pressure, and invigorates. And coffee lovers with a cigarette do not know how else to start their day. However, many do not understand that the drug can do some harm. The positive and negative qualities of coffee have been studied up and down, so let's look at them in order.

Composition of coffee

The influence of the drink on the human body follows from the chemical list of the elements of coffee. In order not to be unfounded, let's talk about everything in detail.

Raw coffee beans include carbohydrates, fats, and proteins. It also contains alkaloid compounds such as caffeine and trigonelline. Of the organic acids, the most valuable are oxalic, cinchona, chlorogenic, coffee and citric acids.

The grain is not deprived of mineral salts, tannins, essential oils, water, vitamins, macro- and microelements. Of the latter, it is worth highlighting iron, potassium, nitrogen, phosphorus, calcium.

After roasting, new elements are formed in the beans, for example, vitamin PP. The final chemical list of elements depends on the degree of roast and the type of coffee.

The effect of coffee on the body

  1. Trigonelline. After roasting the beans, a cafeole is formed, it is this compound that makes the coffee aromatic and strong. Trigonelline secretes nicotinic acid, which enhances blood circulation, dilates blood channels, removes cholesterol from blood vessels and prevents atherosclerosis. Lack of vitamin PP in the body leads to a disease such as pellagra. She is characterized by the following symptoms: dermatitis, diarrhea, impaired brain activity.
  2. Caffeine. This element is famous for its properties to excite the human nervous system. Caffeine energizes, tones the body, reduces drowsiness and fights chronic fatigue. It is due to the incoming element that coffee is accused of developing psychological dependence. However, not everyone knows that caffeine is concentrated in plants, tea leaves, cocoa beans, and cola nuts. Accordingly, in order to reduce harm, you need to know the measure in everything.
  3. Chlorogenic acid. It is also found in many plants, but coffee beans hold the record for the amount of this substance. A useful quality of acid is considered its ability to improve nitrogen metabolism. It also normalizes the activity of the gastrointestinal tract. Chlorogenic acid is responsible for the bitterness and astringent aftertaste.
  4. Vitamin R. It is necessary for the human body to strengthen the walls of the capillaries and give them elasticity. Just one cup of coffee drink concentrates the daily value of this vitamin for an adult. In combination with essential oils, coffee has an antiseptic and anti-inflammatory function. And tannins have a beneficial effect on the heart and digestive tract.

Impact of coffee on the digestive system

  1. The drink promotes increased production of gastric juice, which is why patients with peptic ulcer and gastritis should not consume coffee on an empty stomach. The same applies to patients with pancreatitis. However, taking coffee in the morning does not threaten a healthy person.
  2. There have been many studies that prove the effect of the drug on the digestive system and kidneys in particular. Scientists agreed that the drink reduces the likelihood of developing cirrhosis of the liver in those people who are used to drinking alcohol.
  3. Tannins, which accumulate in large volumes in coffee, add bitterness to the drink. They overpower the assimilation of ascorbic acid and vitamin PP, but at the same time slow down the absorption of elements such as iron and calcium by the esophagus. This aspect suggests that the drink is contraindicated for people with anemia (iron deficiency anemia).
  4. Tannins have a beneficial effect on the lining of the stomach, which is why coffee was used many years ago to treat this organ. However, later scientists concluded that the drink only irritates the mucous membranes and leads to even larger ulcers.
  5. Let's talk again about tannins. They are neutralized when milk is added to the drink. As you can understand, the effect of the drink on ulcers is highly doubtful. A mug of coffee causes pain and heartburn for some, while for others it has the opposite effect. But the use of the drink should be coordinated with the attending gastroenterologist.

It should be noted that the positive properties of the drink for the human body become possible only if coffee is consumed in dosage.

  1. Naturally, we are talking about the permissible daily allowance of the drink. An adult can take from 320 to 480 mg without harm. caffeine per day. It all depends on the degree of roasting and the type of grains, one cup of the drink accumulates about 100-130 mg. caffeine.
  2. Women and girls who are expecting a baby should reduce their coffee intake to 200-250 mg. caffeine per day. This figure is equivalent to about 2 circles per day (according to WHO).

  2. Coffee prevents calcium from being absorbed. Moreover, the raw material flushes this element out of the body.

There are many studies and opinions on coffee, the benefits and harms to the human body. Which of them are correct and is there a danger of harming your health by consuming the drink every day?

Composition of coffee beans

Coffee is made from roasted coffee beans. In nature, there are more than 90 varieties of such plants. The most commonly used industrial varieties are Arabica and Robusta.

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

  • Carbohydrates give the body energy, 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 the body's tone, efficiency, concentration. Regulate blood glucose levels.
  • 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), antitumor properties.
  • Macro and microelements: calcium, iron, fluorine, sodium, magnesium, phosphorus, sulfur are involved in biochemical processes.

Is it harmful to drink coffee? 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 contribute to the elimination of toxins from the body. In addition, the membrane contains plant fiber and phenols, which stimulate the work of the gastrointestinal tract.

During roasting, the water content in the beans is reduced 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.

  • The benefits of coffee are used to prevent constipation. Vegetable fiber contained in grains helps in 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 headache. The effect lasts 3-4 hours.
  • The use of coffee for the respiratory system for bronchitis, pneumonia is to remove 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 drink without sugar is useful for the female body when losing weight. It promotes fat burning during exercise due to the increased tone and performance caused by the effects of caffeine.
  • The benefits of coffee for hypotension are known, as it increases blood pressure.
  • Because of its antioxidant content, coffee is a cancer prevention agent in women and men. Antioxidants protect the cell structure from free radicals.

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

Instant drink varieties

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

The production of a granular beverage is identical, only at the end the powder is formed into granules using high pressure steam.

The freeze-dried product is prepared differently. First, a decoction is made from coffee beans and completely frozen, the resulting mass is dehydrated at low pressure. Then the product is crushed into small pieces of irregular shape. The freeze-dried variety, unlike other types of instant drink, preserves the properties and taste of natural grains to the maximum.

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

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

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

Exquisite taste is imparted by spraying aromatized substances (essential oils) onto the grains, the inner side of the package, into ground powder. Why is a flavored drink useful? 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 is harmless, and in some cases even beneficial. Consuming 3 cups of it systematically every day can be addictive (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 appears, tremors of the limbs, consciousness is confused, and a headache is severe.

Important! The safe daily intake of caffeine for humans is 300 mg. Over 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 up the nervous system, improves mood, and increases efficiency. Therefore, it causes psycho-emotional addiction. An addicted person without drinking coffee feels irritation, a headache, his working capacity decreases, and drowsiness appears.

Drink preparation methods

Freeze-dried coffee with milk: harm or benefit? When preparing a 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 out of the body, and milk replaces this trace element. The drink retains all the harmful and beneficial properties of natural coffee.

When milk is added to the drink, the accumulation of calcium mineral salts in the kidneys and the formation of stones occurs.

Natural coffee, the benefits and harms for women and men from its use is manifested in an increase in the general tone of the body. The negative effect of the drink causes disturbances in the functioning of the heart, liver, and nervous system. Blood circulation is enhanced, which increases the load on the organs of the cardiovascular system. An increase in stomach acidity after taking coffee increases the strain on the liver.

Flavored coffee beans are ground and brewed in a Turk. It is not necessary to dilute the drink with cream or milk, so as not to spoil the taste of the additives. The freeze-dried or granular soluble product is brewed with boiling water. You can add 2 teaspoons 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 a special taste and aroma. Citrus zest, cloves, and cinnamon are also used. Drinking lemon will help replenish the supply of vitamin C, potassium, phosphorus and magnesium, which caffeine washes away. Lemon has a beneficial effect on the condition of the 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 that reduces the harm from drinking coffee.

To add to a tonic drink, it is best to use lime and buckwheat honey, they help to reduce the bitterness of natural coffee. It is necessary to prepare a drink with honey correctly, the bee product is added to a warm drink (50˚), otherwise all the beneficial properties of honey will disappear.

Harmful impact

What harm does coffee cause to the body:

Harm to women's health

Why 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 an involuntary abortion, bleeding or premature birth can occur. A dangerous dosage is more than 2 cups every day. In case of disturbances in the work of the heart and vascular system in the expectant mother, children may be born with a lack of body weight, 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, negatively affects ovulation and the contractility of the fallopian tubes.

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

Important! With frequent coffee consumption, women need to replenish the loss of fluid in the body. You should drink at least 2 liters of clean non-carbonated water daily.

The systematic use of an instant freeze-dried product without constant physical exertion leads to the formation of cellulite in women on the hips and abdomen. The drink disrupts blood flow, contributes to the violation of 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 the stronger sex decreases. The 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 stress hormones 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 is the risk of developing enuresis (urinary incontinence). American scientists have found that drinking 3 cups of natural drink per day increases the possibility of urinary incontinence by 70%.

When you can't drink coffee

The main contraindications:

  • Hypertension. Caffeine increases blood pressure and can lead to a hypertensive crisis. People who constantly drink coffee do not have an increase in blood pressure due to addiction.
  • For insomnia. The drink tones up and invigorates the human body even more.
  • The harm of coffee is manifested in gastritis, gastric ulcer, duodenal ulcer. Chlorogenic acid causes irritation of the mucous membranes, heartburn and exacerbation of diseases of the digestive tract appear. It is especially harmful to drink a flavored drink in the morning on an empty stomach.
  • In polycystic ovary disease, caffeine helps to accelerate the growth of cysts. This is a hormonal type disease, and coffee can disrupt the normal balance of hormones in a woman's body.
  • Pregnancy and lactation are the main contraindications due to the risk of premature birth and harm to the health of the fetus.
  • Atherosclerosis is one of the contraindications, as caffeine increases blood cholesterol levels. This substance is affected by cofestol contained in grains. It acts on receptors in intestinal cells that transport bile acids from the liver.
  • Coffee is contraindicated in osteoporosis (decreased bone density, increased fragility of bones) in the elderly, especially in women, since the drink washes out calcium, phosphorus and magnesium, which are necessary to strengthen bones.
  • With diseases of the nervous system, since caffeine increases the excitability of the brain.
  • Heart pathologies: tachycardia, arrhythmia. The drink dilates blood vessels, disrupts the heart rhythm.
  • Children and adolescents should not drink a tonic drink, as coffee removes calcium, which is necessary for a child's body for normal growth.

In case of an overdose, the harm of coffee is manifested in the occurrence of insomnia, nausea, vomiting, and dizziness. Excitation of the central nervous system occurs, tremor of the limbs, confusion, migraine may appear. The heartbeat becomes more frequent, the rhythm of its work is disrupted, blood pressure rises.

Is coffee good for human health? When used correctly and in the absence of contraindications, a flavored, black or freeze-dried drink will give vigor, increase efficiency and mood. And the addition of lemon, honey will help reduce the negative effects of caffeine.

It's hard to find another product that is as controversial as coffee... Articles appear in the media with enviable regularity, which talk about the results of regular studies that have proven the harmlessness or even usefulness of coffee. How much can you trust such research? And what about research proving the harm of coffee?

In this article I do not pretend to be absolutely objective - I myself gave up coffee a few years ago, having gone through 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 have no idea how to wake up without coffee in the morning? What is coffee based on?

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

The caffeine effect lasts for several hours. Then fatigue appears.

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

In very high doses (about 10 grams) it causes death.

All of the above does not speak about the harm or benefits of coffee, but it clearly indicates that coffee actively affects the human body and is by no means a neutral product. So, can coffee have health benefits, and in what cases? Does the regular use of this drink cause harm, and which one? And finally, what outweighs - harm or benefit of coffee?

Let's analyze the pros and cons of coffee and draw our own conclusions.

The harm of coffee.

Coffee is physically addictive.

To determine if you are addicted to caffeine or not, you need to stop drinking coffee and other caffeinated beverages for a while. If there is an addiction, symptoms such as:

  • headache,
  • tiredness and drowsiness
  • irritability,
  • deterioration of mood, from mild depression to depression,
  • nausea,
  • muscle pain.

Some or all of the above symptoms may appear.

When you get used to it, the tonic effect of coffee gradually decreases and an ever larger dose is required to achieve the same effect. The higher the dose, the stronger the addiction, the more harmful coffee is and the more difficult it is to quit.

The harm of coffee to the nervous system.

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

Mental health risks of coffee.

Consuming large amounts of caffeine can lead to the development of various psychoses, epilepsy, and paranoia. May cause unmotivated aggression.

The harm of coffee to the heart.

Coffee enhances cardiac activity, stimulates the vasomotor center, and quickens the pulse. Caffeine has a short-term effect on blood pressure - it causes 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 more coffee you consume, the higher the risk.

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

  • The presence of diseases of the cardiovascular system.
  • Hereditary predisposition to diseases of the cardiovascular system.
  • Other factors contributing to these conditions (weight, diet, physical activity).
  • The amount of coffee consumed.
  • How to prepare the drink: brewed coffee is much more harmful to the heart than coffee made in a coffee maker.

Coffee interferes with absorption and flushes out important trace elements from the body.

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

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

This leads to many serious problems:

  • Due to a lack of calcium, teeth deteriorate, bones become fragile, osteochondrosis may develop. perfectly flushes calcium from the body.
  • Imbalance in the calcium-magnesium system leads to chronic pain in the back and cervical spine.
  • Lack of vitamins B1 and B6 leads to problems with the 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 a 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 to cut later than they should.
  • The child's height is lower than that of their peers.
  • A child is born with a caffeine addiction.

The consumption of products containing caffeine (and this is not only coffee, but also chocolate, cocoa-cola, etc.) causes great 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 has been said about adults is relevant for children. The only difference is that a much lower dose of caffeine is enough to harm the child's body.

The harm of decaffeinated coffee.

The health risks of coffee discussed above are linked to caffeine. The main argument against decaffeinated coffee is that it doesn't use innocuous chemicals. Is it really so? There are several ways to remove caffeine from coffee beans (decaffeinate):

  1. The "traditional" method in which a solvent is used to remove caffeine is methylene chloride (methylene chloride - dichloromethane, methylene chloride - a colorless liquid with a chloroform odor that has a narcotic effect) or ethyl acetate (a colorless liquid with a fruity odor). Recently, ethyl acetate is mainly used. After the caffeine is separated, some solvent remains in the beans. The thinner may be harmful to health.
  2. The "water only" decaffeinating process 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 the use of compressed gas (carbon dioxide CO 2). Carbon dioxide does not leave any traces in the drink and impairs its taste and aroma.

Thus, only the "traditional" decaffeinating method adds harmful chemicals to coffee. But keep in mind that decaffeinated coffee does contain caffeine, albeit in smaller doses than regular coffee. For example, 10 cups of instant coffee, which says “caffeine-free” on the can, contains the same amount of caffeine as two cups of regular coffee.

In addition, decaffeinated coffee has a negative effect on the cardiovascular system and promotes fat storage. This coffee raises the level of bad cholesterol in the blood, which in large quantities leads to serious arterial disease.

The benefits of coffee.

Oftentimes, the argument in favor of coffee is said to have an invigorating and stimulating effect. In my opinion, this property of coffee can in no way be called good for health. As mentioned at the beginning of the article, caffeine is a psychostimulant and stimulates the nervous system. What harmful consequences this effect leads to, they say.

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

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

Benefits of coffee in preventing cancer.

About two cups of coffee a day reduces the risk of cancer of the following types:

  • 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, for women to prevent this disease, it is enough to drink coffee in moderation, and men need large doses to achieve the same effect.

Benefits of coffee in preventing diabetes.

Coffee can prevent diabetes. In order to reduce the risk of diabetes by 50%, men should drink about 6 cups of coffee. Women will get a slightly less 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 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 - the mobility of sperm increases.

Benefits of coffee for weight loss.

The stimulating effect of caffeine can help you shed those extra pounds. 1 cup of coffee makes aerobic exercise one-third more effective at "burning" calories. In diets and sports, coffee forces the body to use fat instead of carbohydrates for energy.

The benefits of coffee for digestion.

Coffee and caffeinated beverages (such as Coca-Cola) are often used for digestive problems and indigestion.

It is believed that coffee helps the absorption of food, for which it is necessary to offer a cup of this drink after dinner. Truth be told, this raises the question - what to do with minerals, the assimilation of which coffee just interferes with? Apparently, assisting in the assimilation of food is not about helping the body to assimilate nutrients. It's not entirely clear what the benefit is.

The benefits of coffee in medicine.

This is, of course, not about the drink itself, but about caffeine. In medicine, caffeine is used:

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

Caffeine is one of the ingredients in some medicines. In this case, we are talking about the treatment of existing diseases. These drugs 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 healthy?

The above arguments for and against coffee, on closer inspection, are not so contradictory. In certain cases, the obvious disadvantages of coffee can be offset by its beneficial properties. Everyone can decide whether to 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 medical conditions, but it has many side effects. In my opinion, for a healthy person, coffee is more likely to do harm than good.

For the prevention of diseases, it is proposed to consume rather 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

The health effects of coffee are a favorite topic of controversy between coffee lovers and haters. It has been going on since time immemorial and is unlikely to ever end. After all, both sides consider the effects of coffee on health, based on the results of scientific research. Exactly so - in terms of facts! And I must say that scientists from all over the world have made more than 19 thousand studies about the effect of coffee on health. And their results do not yet make it possible to objectively lean to one side or the other. They find out that coffee causes cancer, then they find out that it cures diabetes. How can you determine what the real effect of coffee on health is? I think everything is individual here.

When considering the effects of coffee on health, approach this issue individually. That is, ask yourself the question: "What is the effect of coffee on my health?" And listen to your body. If you feel like coffee, then drink it. And if your body is against, then do not force yourself, even if you are sure that the effect of coffee on health is very positive.

Periodically, coffee consumption in a particular country decreases or increases. But in general, the balance of coffee consumption in the world remains. And, whatever the effect of coffee on health, its consumption all over the world is only increasing every year.

Recently, analysts have noted a slight decline and redistribution of the structure of coffee consumption in Russia. And this is connected not only and not so much with economic reasons (rising inflation, rising prices), but with the increased attention of Russians to their health and the development of a culture of drinking coffee in Russia. The last two reasons are forcing Russian coffee lovers to study information about the effects of coffee on health. And, of course, switch from a soluble to a natural product, because everything natural is more useful than that which has undergone any processing. But is it? Let's take a look at the composition of a coffee bean.


So, fresh coffee beans contain about 2 thousand substances that form the effect of coffee on health. Among them are water, caffeine 0.65-2.7%, fat 12%, proteins 13%. During the roasting process, the composition of the coffee beans changes. The degree of change depends on the degree and duration of the roast. In particular, the caffeine content increases to at least 1.3%. And in the process of making instant coffee, the caffeine content generally increases to at least 5%. Also, considering the effect of coffee on health, it must be said that the coffee bean contains potassium, calcium, magnesium, iron and other trace elements. Roasted coffee beans contain PP vitamin, pyridine and other vitamins.

Draw conclusions. For example, if we consider the invigorating and energizing effect of coffee, then the stronger effect of coffee on health is obtained if this coffee is instant. Although here you need corrections for the excitability of your nervous system. For some, the "horse" dose of coffee does not have any activating effect. Thus, we can once again draw this conclusion: the effect of coffee on health is so individual that there will probably never be any general opinion here.

The harm of coffee

Academician Pavlov studied the harm of coffee to the human body. And to this day, scientific battles do not subside, confirming or refuting the harm of coffee to the body. However, there are proven facts about the dangers of coffee for the human body. Let's take a look at them.

The harm of coffee to the nervous system

In fairness, it should be said that in certain doses of coffee improves reaction, increases physical activity, brain excitability, mental and physical performance, and stimulates the respiratory center. Again, in optimal doses, it reduces fatigue and drowsiness, weakens the effect of sleeping pills and narcotic substances.

However, the harm of coffee is that it is very difficult to independently determine this very dose. After all, the effect of caffeine on each person is individual, and depends on the type of nervous system. And even a small and not very long-term excess of the individual dose leads to depletion of nerve cells, disruption of the normal functioning of the body.


That is why coffee should never be given to children. The harm of coffee for children is enormous. Coffee disrupts the growth and development of a child.

By the way, no one, even avid coffee lovers, should drink it before bed. The last cup should be drunk at least a few hours before bedtime.

Harm to coffee for the heart

It has been proven that coffee enhances cardiac activity, stimulates the vasomotor center, and increases the pulse rate. It also increases blood pressure, albeit briefly and insignificantly. Thus, the harm of coffee for people with arterial hypertension, coronary heart disease and other diseases of the cardiovascular system is visible. And also for those who are predisposed to these diseases. By the way, people who drink more than 6 cups of coffee a day are also at risk of becoming heartbroken.

An interesting fact is that the harm of coffee to the cardiovascular system depends on the way coffee is prepared. Brewed coffee is, in this sense, much more harmful than a coffee machine drink.

Harm of coffee to the urinary system

If a coffee lover suffers from diseases of the kidneys or other organs of the urinary system, then it is better for him to refuse to use this drink. The harm to coffee in this case is that it has a diuretic effect. But if you don't have the strength to refuse, then at least drink more water. Optimally - a glass of water for every cup of coffee you drink.

Harm of coffee for pregnancy

Scientific figures, as they say, cannot be trampled on. Scientifically proven harm of coffee for expectant mothers. If a woman drinks at least 4 cups of coffee a day during pregnancy, the risk of termination of pregnancy is about 33%. But as soon as a pregnant woman reduces her coffee consumption to 3 cups, the harm of coffee drops rapidly. The risk of fetal death in the womb is reduced to 3%. The harm of coffee is especially strong during pregnancy from 20 weeks.

Harm of coffee for the content of trace elements in the body

It is well established that coffee interferes with absorption and flushes out calcium, magnesium, potassium, sodium and some other trace elements from the body. Therefore, if you like coffee, be sure to take vitamin complexes or eat more foods rich in the above microelements. For example, after drinking a cup of coffee, eat 15 grams of almonds - this will return the calcium balance to the proper level.

The harm of coffee in this sense affects women more than men. Surprisingly, this is a scientific fact. If a woman drinks more than 4 cups of coffee a day, then she has a very high risk of developing osteoporosis. This becomes especially dangerous after the onset of menopause. So coffee lovers should be especially careful about their bones and be sure to take calcium.

The harm of decaffeinated coffee

Some people think that by drinking decaffeinated coffee, they are saving themselves from harmful effects. This is true when it comes to caffeine. But at the same time, another danger arises. After all, to rid coffee beans of caffeine, they are treated with chemicals. And it is not clear which is more harmful.

Harm of coffee for the whole body as a whole

And finally, let's look at the harm of coffee to humans in general. Coffee is addictive. And this is also a proven scientific fact.

Exceeding his individual dose, a person forms an addiction in himself. Now he simply physically cannot refuse coffee, the body reacts with severe fatigue, drowsiness and even depression. But at the same time, over time, the effect of caffeine is weakened and in order to achieve the same effect, a person has to increase the dose of coffee he drinks. And what does this lead to - read above.

And now about the benefits of coffee

Recent scientific research unanimously reiterates: "The benefits of coffee are undeniable!" The benefits of coffee, according to them, are so great that it is simply impossible to list all the positive effects. Judge for yourself what the benefits of coffee are.

Undoubtedly, the benefits of coffee as a means of improving mental and physical performance. Scientists have even proven the benefits of coffee for enhancing thinking ability through scientific experimentation. True, this applies only to those who are engaged in logical thinking.

The mental health benefits of coffee are also reflected in the fact that it increases resistance to stress. It also reduces the risk of depression and suicide, and the risk decreases with the increase in the amount of coffee consumed.

The health benefits of coffee are great. Just 2 cups of coffee a day reduces the risk of liver, pancreas, colon and rectal cancer. And smokers have a risk of blood cancer. Coffee reduces the risk of developing Parkinson's disease; for this, women need to consume coffee in moderation, and men in large quantities. Coffee reduces the risk of getting sick with diseases such as hypertension, hypercholesterolemia, asthma, migraine, cholelithiasis, liver cirrhosis, heart attack, atherosclerosis. 6 cups of coffee a day reduces the risk of diabetes in men by half and in women by a third.

The benefits of coffee for men are especially noticeable. It improves male fertility by increasing sperm motility.

The benefits of coffee are very well known for those who want to lose those extra pounds. Just 1 cup of coffee allows you to work out in the gym one third more intensively than usual. And in diets and sports, coffee forces the body to use not carbohydrates for energy, but only fat. What do you think? In my opinion, the benefits of coffee are obvious! And also the benefit of coffee for preserving youth and beauty lies in the fact that coffee contains antioxidants.
