The variety of brands, varieties and methods of coffee preparation is amazing. Fans of this aromatic drink are countless. But how useful is it, and can it harm the body? In some cases, the benefits of coffee are much greater than the harm. You just need to know how much and how to use it.

The positive effect of natural coffee

Coffee beans contain caffeine. On average, 1500 mg / l. Caffeine has an exciting effect on the nervous system, increases heart rate, and raises blood pressure. As a result of drinking coffee:

Mental activity increases;

Working capacity increases;

Drowsiness decreases.

From a medical point of view, the most benefit from natural ground coffee. It is poured with boiling water and heated until it boils. In this case, the aroma is retained, and the caffeine does not completely pass into the water. For 100 g of water, take 10-15 grams of ground grains. In order not to grind coffee beans at home, you can buy ready-made or go to one of the coffee houses, where they will prepare the aromatic mixture you need.

Influence on organs

You cannot abuse any coffee. It affects the kidneys, heart, liver, stomach. They get used to it and begin to increase the dose every day. Excessive consumption of coffee causes:

Nervousness;

Headaches;

Insomnia;

Tachycardia;

Diseases of the stomach;

Joint pain.

Coffee can stain tooth enamel, giving it a yellowish tint. The strongest effect is on the central nervous system, liver and stomach. Coffee prevents liver cells from dividing, which is harmful for healthy people, and is useful for cirrhosis and fatty disease.

Studies have confirmed that coffee does not affect the development of coronary heart disease when drunk in normal amounts. Caffeine increases blood pressure, but for hypotonic people it is even beneficial, and for people with normal blood pressure it has an invigorating effect. For those who suffer from hypertension or heart disease, it is better to refrain from coffee.

Usage rate

Doctors warn that no more than 4 cups of instant coffee can be drunk per day. For pregnant women, this portion is reduced by 2 times, provided that the doctor does not prohibit it.

These restrictions are related to the daily intake of caffeine. It should not exceed 400 mg for an adult. A cup of Americano contains, on average, 100 mg of this substance. But it must be borne in mind that the varieties, methods of roasting, grinding are different. This changes the strength of the drink. The stronger it is, the less it is drunk.

Men are also advised to consume no more than 3-4 cups of coffee a day. Exceeding the norm leads to a jump in blood pressure, reduces potency, and disrupts sleep. It is better to opt for natural ground grains, since they contain more nutrients.

The harm and benefits of coffee with milk

Milk or cream is added to soften the taste and reduce the caffeine concentration. At the same time, the calorie content of the drink increases, and if we take into account that sugar is often put along with milk, then the benefits of the drink are rapidly reduced.

Drinking coffee with milk in large quantities is also harmful. In the stomach, it leads to the formation of insoluble compounds, which are deposited in the kidneys, negatively affecting the bladder. But no one forbids drinking 1-2 cups, even pregnant women.

Soluble and freeze-dried

Instant coffee is made from green beans that are roasted, ground, and subjected to an extraction process - boiled and evaporated. After that, the extract is crushed, turning into granules familiar to everyone. Flavors and preservatives may be added to enhance odor and reduce oxidative stress.

The concentration of caffeine in instant coffee is higher and it has a higher acidity. It is especially harmful to people with a sick stomach, as it irritates the mucous membranes. It is not recommended for those who have liver, kidney or heart problems.

Freeze-dried coffee essentially the same soluble. Only in the production process there is a process of sublimation - drying by freezing (freezing in a vacuum). This is an expensive process and therefore the price of the freeze-dried product is higher. In freeze-dried granules, more initial substances are retained, they are more useful and aromatic.

Is decaf coffee harmful?

The absence of caffeine itself is beneficial, but a lot depends on how it was extracted. The caffeine is removed by washing with an ethyl acetate solution with either water or compressed carbon dioxide. The last two methods are considered the safest.

Decaffeinated coffee promotes fat storage and increases the levels of bad cholesterol in the blood.

The caffeine is not completely extracted, a small percentage of the substance remains, so the drink still has a stimulating effect, but to a lesser extent.

The benefits of green coffee

To obtain green coffee, beans are cleaned and dried in a special way, excluding the roasting process. As a result, most of the nutrients are retained, while the concentration of caffeine decreases.

Green coffee contains unsaturated fatty acids, vitamins, antioxidants. Since green beans still contain caffeine, you should not abuse the drink. It can increase blood pressure and speed up your heart rate.

Adding cinnamon, lemon, brandy

Cinnamon gives the drink a special aroma and helps to lose weight. Coffee with cinnamon speeds up metabolic processes, relieves spasms in the bile ducts, lowers the level of bad cholesterol. This is its benefit. It is important to drink it without high-calorie supplements.

As in tea, lemon is sometimes added to coffee, this does not make the drink worse. It acquires exotic taste and beneficial qualities by supplying the body with vitamin C.

As for coffee with cognac, many people like this drink. It relieves stress, accelerates blood circulation, helps fight colds and increases blood pressure. But cognac, both on its own and in combination with coffee, is not recommended to be abused. The drink can be addictive. It is not advised to drink it for hypertensive patients and those who have liver problems.

Adding honey and cardamom

Coffee with honey will become a good immunomodulator, protect against flu and colds. For honey to be beneficial, it must be added to cooled coffee, the temperature of which is no more than 40 °, or consumed separately from a spoon.

Recipe for coffee with honey and lemon. Brew coffee from ground beans, cool slightly, add a teaspoon or balm, a slice of lemon, honey to taste.

Cardamom helps to reveal the aroma of coffee. It is added in small amounts to neutralize the negative effects of caffeine. Coffee with cardamom helps with bronchitis, eliminates colic in the stomach, relieves nervous tension. For gastritis or stomach ulcers, it is prohibited to drink coffee with cardamom. Together with cardamom, you can add vanilla, cloves, cinnamon to the drink. There are recipes with milk and cream.

Slimming coffee, adding ginger

Being on a diet, wanting to lose extra pounds, or just keeping yourself in shape, you can not eat a lot of sweets. Cream should not be added to coffee, and the amount of sugar should be minimized or completely discarded.

Coffee itself is a low-calorie beverage when drunk without sugar. It removes fluid from the body, which contributes to weight loss.

To enhance the slimming effect, recipes for coffee with ginger are used. These two products help you to lose extra pounds faster, speed up the processes of food absorption and the breakdown of fats.

Coffee made from barley, acorns and with chicory

Barley and acorn drinks are not complete coffee. It is a surrogate that helps replace the expensive and not always healthy coffee bean drink.

Barley coffee is made from roasted barley grains.

What is its use? Barley contains fiber, many vitamins and minerals. It strengthens the immune system, has a diuretic effect, and soothes the nervous system.

Drinking ground acorns lowers blood sugar levels. It is useful for diabetics. Acorn coffee normalizes heart function, has a bactericidal effect, and helps to get rid of coughs.

Chicory is considered a medicinal plant. Its root contains inulin, which improves the intestinal microflora, has a beneficial effect on the liver and pancreas. Sometimes chicory is completely replaced by coffee, but to preserve the invigorating properties of the drink, coffee is left, adding chicory to it.

The benefits and harms of 3 in 1 coffee

For its quick and easy preparation, people love the instant drink called 3-in-1 coffee. But is it useful, and can it be used often? One packet contains instant coffee and dry cream. Vegetable cream is used, which is very different in properties from animal fats. Glucose syrup for sweetness, stabilizers, thickeners, flavors are also added. The 3 in 1 drink is high in calories. It cannot be drunk by those who have decided to lose weight.

There is no harm from such coffee, if you use it on rare occasions when circumstances force. But drinking in large quantities every day is still not worth it.

In moderate doses, caffeine is considered beneficial. In the video, the doctor tells how much coffee is beneficial and how much harm. What kind of disease he provokes.

So, the maximum benefit is provided by natural ground coffee. But you have to be careful with him. It is enough to drink 2-3 cups a day, after having eaten something. If you add a few healthy ingredients, you can change the taste of the drink and improve your health with it.

Most of humanity cannot imagine their morning without coffee - an invigorating drink that instantly relieves sleep. Some coffee lovers enjoy the process, inhaling the aroma and sipping a little of the drink, and can do this several times a day, even on their day off. The second part of people drinks coffee exclusively to quickly wake up their bodies, so as not to be late for work or a meeting. But they all have one thing in common - the need for coffee!

The benefits of instant coffee

Instant coffee is obtained by prolonged processing of coffee beans. For its production, grains are selected that have lost their presentation, or are not of very good quality. The end product is crammed with additives, colors and flavors. The powder that is obtained as a result of processing has nothing to do with coffee beans, except for the origin.

By and large, instant coffee does not benefit the body, whatever you choose - powder, granular or freeze-dried. Although many argue that the freeze-dried analog is still useful. In fact, he retains a little more properties than his younger brothers, but at the same time his price is higher. So is the difference in price between natural and freeze-dried drinks worth the lost qualities?

All that you can get from a cup of such coffee is a weak imitation of the natural one. Such coffee can give your body vigor, accelerated work of all organs, quickened pulse and energy.

What is freeze-dried coffee and how is it useful?

Freeze-dried coffee is obtained by roasting, grinding into a powder, removing water and freezing a natural product. The result is pyramids (granules), which do not contain dyes and flavors.

There is a lot of controversy around freeze-dried coffee: some argue that this is the healthiest coffee, others insist that it is just an analogue of natural coffee, although it is made from beans of not the worst quality.

Freeze-dried coffee is an instant drink that contains less caffeine, like other components lost in the two thermal treatments. The undeniable advantage is the lack of additives.

The benefits of freeze-dried coffee are the same as those of the general group of instant drinks, but this option is not harmful to the body, due to the lack of additives.

His tandem with coffee is definitely useful, but contraindicated for children, pregnant women, people with diseases of the gastrointestinal tract and the nervous system.

4. Gastrointestinal disorders ... It is very harmful to drink coffee in the morning on an empty stomach or together with a cigarette. This is actually a verdict on the stomach.
5. When non-compliance with recommendations taking coffee can dehydrate your body. Coffee lovers often make the huge mistake of substituting coffee for drinking water. Thus, the beneficial substances are gradually washed out, while the water balance is completely disturbed. The result is skin diseases, weakness and rapid cell aging

This drink has been known to the world for more than one century. Some say that its frequent use can cause impotence and insanity, others argue that it is a natural energy drink. All these statements are about ground coffee, the benefits and harms of which are the subject of controversy not only by ordinary consumers, but also by scientists. Research on the drink is still ongoing. What are the objective scientifically proven facts that indicate the advantages and disadvantages of coffee?

Caffeine is one of the most commonly used psychoactive substances in the world. It is he who is the main constituent of coffee beans. Its effect on the human body has been studied quite well. But besides caffeine, beans contain more than a thousand different substances.

It is known for sure that the benefits of ground coffee lie precisely in the combination of caffeine with lipids, organic acids and soluble carbohydrates. At the moment, scientists from around the world have confirmed several facts about the benefits of natural coffee (both in beans and ground). It should be noted that the facts listed below do not apply to the instant version of the drink.

• Drinking natural ground coffee increases physical stamina.

If you drink a cup of espresso about an hour before your workout, you will notice that your endurance will increase significantly. Caffeine raises adrenaline levels in the blood, thereby preparing the body for exercise.

• Coffee can block hunger and help you lose weight.

Unroasted green beans are high in magnesium and potassium. It is these trace elements that help the human body produce insulin, regulate blood sugar levels, thereby reducing hunger and cravings for sweets.

• Caffeine burns fat.

It has been proven that fat cells are destroyed under the influence of special fatty acids, the production of which provokes caffeine.

• A coffee drink helps you focus and invigorate.

Drinking espresso in moderation (no more than three cups a day) reduces mental fatigue and improves response.

• Coffee lovers are less likely to suffer from various diseases.

Drinking natural ground coffee in moderation reduces the risk of developing cancer. Several studies have shown that a set of unique chemical elements in the composition of coffee beans can help reduce the risk of prostate cancer by 25%, and endometrial cancer by 20%. At the same time, patients in the experimental group consumed four cups of strong coffee a day.

Caffeine is beneficial for the prevention of basal cell carcinoma (the most common type of dermal cancer).

Also, fans of natural coffee can boast that they are less likely to develop stroke and Parkinson's disease.

This is not surprising, since caffeine increases the activity of brain cells. Overall, coffee drinkers have a 25% lower risk of premature death than those who refuse to consume the popular drink.

• Coffee drinkers age more slowly.

Coffee beans contain many antioxidants that fight free radicals. This means that the aging process of the body slows down significantly.

• Natural coffee improves mood, helps fight depression and even prevents the development of suicidal thoughts.

Caffeine stimulates the central nervous system and increases the production of mood-lifting neurotransmitters (serotonin, dopamine, and norepinephrine).

The harm from drinking ground coffee

Before listing the negative aspects of ground coffee, it is necessary to focus on the fact that they appear only when the drink is abused. The lethal dose of caffeine is only 10-15 grams. Of course, it is unrealistic to get poisoned with coffee, because you will have to drink about 80 cups of the drink at a time. But one must remember that any product can be both a medicine and a poison.

It all depends on the dosage. Also, we must not forget about the quality of the drink. It is best to buy well-known or proven brands. The danger of cheap ground coffee is that there may be toxic impurities in the pack (except for the directly ground coffee beans). Unscrupulous manufacturers try to increase the total weight of the pack in this way. Regular consumption of low-quality coffee drink can provoke intoxication, headache and even some dangerous diseases.

• Coffee can cause insomnia.

If a person drinks more than 4 cups of strong espresso in the evening, then it will not be possible to fall asleep quickly and easily. The increased level of adrenaline in the blood and a large amount of released dopamine will not allow the body to relax and calmly go into "sleep" mode.

• Caffeine raises blood pressure.

If a person with hypertension drinks at least 2 cups of espresso, they will suffer from high blood pressure for the next 2-3 hours. This effect should be taken into account for those who do not experience problems with pressure, but are planning to go diving in the near future. For those suffering from hypertension, it is better to give up caffeine altogether, because 4 cups of the drink can provoke not just an increase in blood pressure, but also a heart attack.

• Coffee women are more likely to suffer from problems with conceiving and bearing a child.

Caffeine significantly reduces a woman's ability to conceive. And already pregnant women who drank at least two cups of espresso a day are 30% more likely to lose their baby early than those who completely cut caffeine.

• Coffee provokes vigorous heartbeats.

Anyone who has drunk several cups of strong espresso may notice that their heart begins to beat more vigorously. This is due to the increase in adrenaline levels already described above. Healthy people easily tolerate this side effect, but those who suffer from any diseases of the cardiovascular system are at risk of getting a heart attack.

• Caffeine flushes calcium out of bones.

Regular consumption of large quantities of ground coffee can lead to the fact that the bone tissue becomes fragile and thinned. Doctors have long noticed that the bones of coffee lovers heal much longer than those who prefer to drink plain water.

• Drinking coffee can damage your hearing.

Of course, those who consume espresso on a daily basis will not go 100% deaf. So far, it has only been scientifically proven that an excess of caffeine does not allow you to quickly restore hearing after aggressive noise exposure.

To drink or not to drink? It all depends on your overall health!

Before brewing another cup of coffee (or, on the contrary, giving up the daily ritual), you need to remind yourself once again that any product is both useful and harmful. One of the best-selling products in the world is ground coffee.

The health benefits and harms of drinking this drink have been studied for decades by independent and highly reputable organizations. Therefore, all of the above facts can be called confirmed.

One cup of espresso a day is unlikely to cause significant damage to health. But drinking even the highest quality coffee in unreasonable quantities will definitely not bring any benefit.

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 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 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 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 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.

Beneficial features

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. Drinking it regularly, 3 cups 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, calcium mineral salts accumulate in the kidneys and stones form.

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 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 per day 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 bloodstream. 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.

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 are considered the record holders 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 mug 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.
