We can safely say that in the history of coffee there is no louder geographical name than Mocha (one of the variants of the name of this port is Moha, it is most often used from the Middle Ages to the present day). This small Yemeni port on the Red Sea gave its name to the Arabian coffee.

Until the end of the 17th century, the world as a whole (albeit to a limited extent) received coffee only from Yemen. It was that real and famous Mocha or Mokka coffee. Until the middle of the 17th century, Turkish and Egyptian merchants came to Yemen and received the best grain. They bought crops directly from the trees, provided harvesting and processing of seeds. The coffee was prepared by the dry method, that is, it was dried in the sun.

The Arabs were extremely proud of the new drink and kept secret the secret of its preparation. They banned the export of grain from the country if they are not dried. This measure was aimed at ensuring that not a single seed capable of sprouting fell into the hands of strangers, who, of course, were forbidden to visit coffee plantations. Nevertheless, one can guess that it was very difficult to maintain full control. Arabia was always visited by many pilgrims who came to Mecca from afar, and one fine day the wonderful drink inevitably had to become known to everyone. This happened around 1650, when a Muslim pilgrim named Baba Budan managed to obtain seven green coffee beans and smuggle them out to the Chikma-ghalhur region of southern India. These seeds have grown into excellent coffee trees, which laid the foundation for the production of coffee in this country.

Countless attempts by the Portuguese, Dutch, French, Venetians, Spaniards to steal seeds from the Arabs ended in failure. Finally, in 1690, the Dutch managed to get some sprouts of the coffee tree, which were carefully grown in the botanical gardens of Amsterdam. From there, in 1699, coffee trees were brought to the Dutch colonies on the islands of Java and Sumatra. Trees grew well in tropical climates. A few years later, the colonies became the main supplier of coffee in Europe, which is the main merit of the Dutch East India Company founded in 1602. Amsterdam soon became not only a center for the spice trade, but also a world center for the coffee trade. Experienced traders, the Dutch artificially maintained monopoly high prices for a variety of spices, including coffee.

Residents of Dutch cities quickly appreciated coffee, but, unlike foreigners, preferred to drink it mainly at home. Proud of their agility and high income from the sale of coffee, they even showed a rare leniency towards their long-term competitors – the French. In 1714, the burgomaster of Amsterdam, Nicholas Whitson, presented a one and a half meter coffee tree to Louis XIV. By this time, the Sun King was already well aware of the merits of the new drink, which was consumed by his entire court. They even say that the idea of sweetening coffee with sugar came to the mind of one of his many mistresses (this idea is not new: at the beginning of the 15th century, the Egyptians already drank coffee with sugar).

Invigorating component and its action

The well-known tone of the body, high spirits from drinking a cup of coffee – all this causes caffeine. In the composition of an instant drink, by the way, it is much less. This alkaloid is also present in a number of other products: cocoa, tea, cola.

How does this happen

The body’s sleep and wakefulness are controlled by special receptors in the brain. A substance called adenosine makes people sleepy. But coffee, whose molecular structure is close to adenosine, replaces this substance, preventing it from reaching the very receptors. As a result, the desire to sleep disappears. This coffee effect lasts for about 5 hours. Therefore, it is better to drink the drink no later than 6 hours before bedtime.

People’s reactions to an invigorating drink are individual, but they can be summarized in the following list:

drowsiness disappears, the brain and physical functions are activated;
blood circulation increases, blood pressure rises, heart rate increases;
metabolism improves, appetite appears.
An interesting fact: in a rare category of people, the mechanism of action of coffee is completely opposite. They feel fatigue, drowsiness. The reason for this is genetic characteristics. Instead of sleep receptors, caffeine blocks other “sensors” of alertness.

Time of action

Caffeine is usually eliminated from the body in a maximum of 3 hours. But the half-life lasts an average of 5 hours. During this time, sleep receptors are still blocked. The peak of the drink’s action, as a rule, falls within the first 15-45 minutes after consumption.

Most feel a strong tone during this period. But for some people, coffee begins to take effect in an hour, not earlier. Sometimes, during the active influence of caffeine, a person experiences nervousness, bursts of energy, and the need to urinate. But these manifestations usually go away with the destruction of the alkaloid. The exception is cases of sensitivity to caffeine.

Attention! It is impossible to prolong the effect of coffee. The first pair of cups will block sleep receptors for several hours. An additional portion will not be able to affect them, but on the heart – very much!

How the drink became popular

In the middle of the 15th century. aromatic grains reached Turkey, from where coffee later came to Russia. This was an important stage in the history of the drink. The inhabitants of Constantinople liked him so much that a few years later the first coffee shop in the world was opened there.

The cooking technology was gradually changing. If earlier the grains simply insisted on water, then the Turks guessed first to fry and grind them. This greatly improved the taste, and coffee began to rapidly gain popularity in the East. The Arabs used to say “kahwa”, that is, “driving away sleep.” The Turks changed the name to “kahwe”, from which the word “coffee” was formed, which has taken root in European languages.

With the emergence of the art of cooking, the drink began to be consumed not only at home, but also to be brewed in public. This is how the history of coffee shops began. At first these were simple huts, but later they turned into luxuriously furnished and cozy establishments, which later began to open in Europe. Coffee houses contributed to the rise in popularity of the invigorating drink, people began to come to them to listen to music, watch performances by artists and exchange information.

However, the history of coffee has not been all that smooth. The coffeemania that swept Turkey in the 16th century worried the authorities. They believed that he was loosening tongues by provoking unwanted conversations about politics. Coffee was banned, sacks of beans were thrown into the sea. However, even this did not make people give up their favorite drink.

Coffee can help you burn excess fat

Did you know that caffeine is found in almost every supplement?

And there are reasons for this. Caffeine is one of the few natural substances that actually helps you burn excess fat.

Some studies show that caffeine can increase your metabolic rate by 3-11%.

Other studies show that caffeine burns 10% fat in obese people and 29% fat in lean people.

However, it is possible that this effect decreases in those who drink coffee regularly.

Bottom Line: Several studies show that caffeine can increase the percentage of fat burned and increase the metabolic rate.

The benefits of drinking coffee

Healthy coffee is ground, freshly brewed, not too strong. Instant coffee, which is sold in cans and is brewed with boiling water, is practically useless. If we are talking about high-quality coffee, then its beneficial properties are manifested in the following:

Coffee is an excellent antioxidant that can compete with most fruits and vegetables. If you don’t like fruits, then this is a great alternative for saturating the body with antioxidants;
Coffee improves blood circulation, which means it contributes to the full supply of blood and oxygen to the whole body, including the brain. It helps to concentrate better, improves mental performance;
The coffee aroma easily relieves nervous tension, tunes the body in a positive way, activates the brain;
Drinking a cup of coffee during the day reduces the risk of developing hepatic pathology by 20%;
The drink stabilizes the emotional background;
Coffee prevents the development of oncological diseases of the skin;
Coffee increases strength performance in athletes, promotes energy gain;
Two cups of spirits during the day reduces the risk of developing type 2 diabetes by 50%;
The habit of drinking coffee every day improves your mood!

How to reduce the negative effects of coffee drinks

In order not to harm health and reduce the negative effects of coffee to a minimum, you need to adhere to the following recommendations:

people suffering from excessive nervous excitability, high blood pressure, preference should be given to decaffeinated drink. True, it is also not worth getting carried away with it. It also contains substances that can have a stimulating effect. In addition, many of them have not yet been studied to this day;
stop drinking coffee before going to bed. It is especially important to adhere to this rule for those who suffer from insomnia;
with diabetes mellitus, drink only weak coffee drinks without added sugar. A maximum of 2 cups are allowed per day;
with an increase in cholesterol, a tendency to pathologies of the heart and blood vessels, atherosclerosis, the drink must be prepared in a coffee maker and using paper filters. It is recommended to completely abandon the instant product. Only natural coffee is allowed;
do not consume espresso on an empty stomach. Due to this, the concentration of gastric juice will increase and there will be a risk of developing an ulcer. If you cannot refuse the morning portion of the drink, it is recommended to add milk to it. Half an hour before that you need to drink at least a glass of water;
if you are prone to obesity, you should refuse to add a large amount of sugar, milk, ice cream and syrups to the drink;
observe the water and drinking regime. You need to drink at least 2 liters of clean water per day. Due to this, it will be possible to replenish the fluid deficit and avoid dehydration;
diversify the diet, eat more dairy products. Thus, it will be possible to compensate for the lack of calcium leached from the body;
it is strictly forbidden for pregnant women to abuse coffee. You need to limit yourself to only 1 – 2 servings per month.

For the drink to be extremely beneficial, you need to drink a maximum of 3 cups per day. In this case, preference should be given to natural grains, rather than an instant product. Thus, it will be possible to avoid the use of all kinds of dyes, flavors and other chemicals that are used in the manufacture of sublimate.

The choice should be stopped on coffee beans marked “Eco”. She points out that neither farmers nor importers used pesticides and pesticides. This is an absolutely clean and safe product.

Concentration problems

When it enters the intestine, the natural alkaloid is almost completely absorbed. This takes approximately 45 minutes. The maximum concentration of caffeine in the blood is observed after only a quarter of an hour after its penetration into the body.

If a person drinks espresso regularly, this effect becomes mild. You have to increase the number of servings, but these actions are in vain. Caffeine no longer helps to concentrate.

Calcium leaching

Another hidden harmful property of coffee on the body is the leaching of calcium and the slowed down absorption of such macronutrients as magnesium, sodium, potassium.

From the obvious results, coffee lovers can observe brittle nails, increased sensitivity of the teeth due to worn out enamel, hair loss. It is not necessary to take calcium preparations immediately after a cup of coffee; it is better to wait 2-3 hours.

In order not to speed up or aggravate this process, you need to drink more water: drink 300 ml of water for every 50 ml of coffee. Not all at once, of course, but during the day. Always keep a rule in mind: the more coffee you consume, the more ordinary water should enter the body.

Addiction

Coffee alcoholism and hangovers are present in most people’s lives if they are accustomed to drinking it on a daily basis. Caffeine causes an increase in the secretion of the hormone serotonin, which stimulates our pleasure centers.

It causes physical dependence, which is accompanied by withdrawal symptoms (withdrawal symptoms, withdrawal symptoms). Headaches, increased irritability, drowsiness – all these are the consequences of refusing coffee.

A coffee lover who decides to give up the drink for several days will experience severe headache, weakness, mood swings, nausea, and muscle pain.

The hormone dopamine, the release of which is stimulated by caffeine, is responsible for feelings of satisfaction and everything related to it. Therefore, with a coffee hangover, people experience a lack of this hormone, and the consequences: apathy and lethargy.

The harm of coffee in the processes of maintaining water balance in the body is a scientifically proven fact.

Because it is a fairly strong diuretic, a substance that helps to remove fluid from the body. Of course, in some situations, such drugs are prescribed specifically in order to activate the circulation of fluid in the body. But in summer heat or in a hot room, this effect of caffeine becomes harmful. Its diuretic effect is worth considering. After all, such a drink will not replenish the fluid balance. Quenching your thirst with a cup of invigorating drink is just an illusion. Coffee can cause dehydration. And a lack of fluid in the body provokes serious disorders. This phenomenon provokes drying out of the mucous membranes, and as a result, the decline of local immunity. That is, the mucous membranes of the nose, eyes and mouth cease to retain microbes. The most striking manifestation of this is the increase in the incidence of viral infections. Risk of catching a cold get sick with conjunctivitis or stomatitis increases significantly. Drying of the mucous membranes can provoke bad breath, dry eyes, and discomfort when swallowing.

The diuretic effect of coffee can be critical for the health of the elderly. But the effect of coffee on the musculoskeletal system is more dangerous. The drink promotes the leaching of calcium from the bones. And in old age, the skeleton is very fragile. For the same reason, the drink is not recommended for children and adolescents during the period of active bone formation. Pregnant women who are actively consuming calcium for laying the baby’s skeleton should also refrain from it.

The invigorating drink also affects the digestion processes. It provokes the release of hydrochloric acid in the stomach. It is designed to digest food. If it is produced uncontrollably and at the wrong time, then a person may have problems with digestion: bloating, flatulence, gastritis, ulcers and heartburn.

Just coffee may act as a laxative. More precisely, it speeds up the process of moving food from the stomach to the intestines, even if it is not completely digested. This interferes with the absorption of nutrients.

So, what harm does coffee bring to the human body as a whole? Here are the facts to make you think:

coffee can raise blood pressure and cause heart problems,
a person who often includes it in the diet is at risk of high blood cholesterol,
coffee is included in the list of substances that can have a carcinogenic effect,
has a diuretic effect, which can cause imbalance in the water balance in the body,
fluid deficiency can lead to a decline in local immunity, cause frequent colds, and lead to problems with mucous membranes,
coffee flushes calcium from bones and can cause osteoporosis,
coffee has a negative effect on digestion processes.

Instant and decaffeinated coffee: harm to health

So, the main active ingredient of this invigorating drink is caffeine. And most of the negative effects are associated with it. Therefore, among coffee lovers who have decided to end their addiction, the decaffeinated type of coffee is so common.

The history of the discovery of this species is also associated with a legend. One of the merchants transported coffee beans on a ship for later sale. During the trip, sea water flooded the cargo. After the wet bags were dried, and the grains were crushed and tried to brew, it turned out that the pleasant taste of the drink was preserved, and its invigorating property came to naught.

Typical example: A person drinks 5 cups a day and is worried that it might harm him. So he switches to a decaffeinated drink. As a result, he now drinks 15 cups a day and is still receiving the same dose of caffeine. Therefore, decaffeinated coffee is not a panacea. He is able to provide all the same negative effects, only in a reduced form.

Another type of drink is instant coffee. The way to get it is as follows. A highly concentrated drink is brewed from ordinary beans, which is then dried to obtain a powder or granules. These granules are easier to transport, cheaper and able to retain their flavor longer. But the instant variety is usually made from grains of low grade or poor quality. Therefore, the raw materials for it are usually of much lower quality.

In addition, the invigorating effect of instant coffee is much weaker, if not completely lost.

It would seem that if there is no invigorating effect, then the harm of coffee should come to naught? This is not true. Theobromine has almost all of the negative effects of caffeine, except those associated with the tonic effect.

Diseases of the cardiovascular system

With diseases of the cardiovascular system, everything is also not simple: either we are told that coffee protects against heart attacks and strokes, then, on the contrary, provokes them. Tired of conflicting judgments, experts at the Center for Food and Health in Northern Ireland decided to find out once and for all.

They looked at 1,277 studies and concluded that 2-3 cups of coffee a day have no negative impact on health and even moderate benefits. But we are talking about coffee cups here.

In Turkey and Italy, they are the size of a thimble, and you and I often pour coffee into the stomach from tea mugs with a volume of 250-300 ml, thereby drinking more than the norm. Of course, with this amount you can bring yourself to a hypertensive crisis, tachycardia, insomnia and exhaustion of the nervous system.

The appearance of puffiness

Caffeine can lead to dehydration. The skin ages faster, puffiness begins to appear on the face. If sugar, milk or syrup is added to the drink, an increase in its glycemic index is noted. There is a jump in blood glucose levels and the formation of cortisol. Due to the intense release of insulin, you begin to want something sweet.

The importance of coffee in the work of digestion and kidneys

What effect does coffee have on the digestive system? Let us analyze how a natural drink is harmful and useful:

The benefit of the drink is that brewed coffee activates the work of gastric juices, which contribute to the digestion process, but this is dangerous for pancreatitis, stomach ulcers and other diseases;
You cannot drink coffee in the morning on an empty stomach – a combination with light cereal carbohydrate or protein foods will be more useful;
The benefits of coffee are in enhancing intestinal motility, which, among other things, contributes to the normalization of weight;
A cup of brewed coffee in a Turk is healthier without sugar and milk – they neutralize the effect of tannins that improve stomach secretion. As an alternative to drinking coffee with sugar – a morning cup of drink with dark chocolate.

Several cups during the day put additional stress on the kidneys, which helps to remove excess fluid from the body – and this is an obvious benefit. However, the drink dries up, so the coffee lover, in order to prevent dehydration, needs to monitor what rate of water enters the body.

Feelings of anxiety

Under the influence of caffeine, the excitability of the cardiovascular and respiratory systems, and the spinal cord increases. The pressure rises and the heart begins to work in an increased mode. Changes occur in the vessels, the central nervous system is excited and the pulse quickens. As a result, avid coffee lovers have a feeling of anxiety and anxiety.

Stomach problems

Coffee contains a huge amount of chlorogenic acids, which add a sour note to the aromatic drink. It is these acids that contribute to the secretion of hydrochloric acid in the stomach, which leads to the development of heartburn.

Caffeine has a direct effect on the organs of the gastrointestinal tract. The result of this influence is a laxative effect and unpleasant cramps. Caffeine also reduces the resistance of the stomach lining to the bacteria Helicobacter pylori, which attacks the stomach and small intestine.

People suffering from gastritis with high acidity are strongly advised not to consume anything with caffeine, let alone coffee.

The gastric mucosa already suffers by itself with such a disease, and when it meets your favorite drink, heartburn sets in, pain worsens, the effect of dietary nutrition and treatment with pills is dulled. If you often violate the ban on coffee with gastritis, then an ulcer may open.

How to give up coffee?

People who have decided to overcome their addiction to a tonic drink recognize that coffee is not a cigarette. You can give up this habit gradually. You can start small, but do not forget about the main goal.

Stop cheering yourself up with a hot drink at least on weekends. Indeed, these days you do not need increased efficiency and active energy. Unhealthy vigor after a cup of coffee can interfere with healthy rest or proper sleep.
Replace coffee with tea. Tea also contains caffeine, and it can also have an invigorating effect. But here the tonic substance is much less. Gradually you need to switch to mineral water, juices and compotes. After all, tea is also not a panacea. And it contains harmful substances, and it can also have a diuretic effect.
Have a new awakening ritual for yourself. If you are a coffee lover with experience, then most likely you have noticed that you are used to caffeine, and he is no longer able to exert its invigorating effect on you. You may just wake up from drinking a mug of something hot. Let it be heated compote, broth or just water.
Get enough sleep. Often the reason for feeling unwell is not a refusal to drink coffee, but a chronic lack of sleep. Get in the habit of going to bed early. And in the morning, try to take time to exercise or jog. It wakes up better than an artificial psychostimulant.

So, there are a lot of myths hovering around the “coffee lovers”. Most of them turn out to be true. It has an ambiguous effect on the nervous system and can cause abnormalities in the work of the cardiovascular system. Coffee is contraindicated for pregnant women and people of old age. It can cause gastrointestinal upset. Scientists put it among the carcinogenic substances. This drink can cause an imbalance in the water balance in the body, and, as a result, lead to frequent colds, problems with mucous membranes and a general decrease in local immunity. But most importantly, with regular abuse of this drink, it completely loses its invigorating properties. All that a person can get with his uncontrolled consumption – forms of addiction and withdrawal syndrome (“withdrawal”).

Harmful properties of coffee for the body

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

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

A few words about caffeine

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

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

The effect of caffeine on each organism is individual and depends on the nature of the reaction of the human nervous system.

Caffeine can neutralize the effects of sleeping pills. But the opinion that an alkaloid is a drug is partially refuted. A strong drink based on coffee beans is physically addictive, but unlike narcotic drugs, it does not cause psychological attachment.

In addition, it has been proven that, with moderate consumption, the beneficial properties of coffee are revealed. The optimal daily volume of a strong drink is no more than two cups in the morning.

Coffee May Lower Your Risk of Type 2 Diabetes

Type 2 diabetes is a huge problem that currently affects over 300 million people worldwide.

This disease is characterized by elevated blood sugar levels and an inability to secrete insulin.

For some reason, coffee drinkers have a significantly lower risk of developing type 2 diabetes.

Studies show that those who drink more coffee are 23-50% less likely to develop the disease. One study even shows 67%.

According to the results of 18 studies, which involved 457,922 people, a daily cup of coffee reduced the risk of developing type 2 diabetes by 7%.

Bottom Line: Some studies show that people who drink coffee more often have a much lower risk of developing diabetes, a disease that currently affects about 300 million people.

Don’t drink too hot

Coffee should be drunk with a temperature below 60 degrees. Otherwise, the risks of esophageal cancer increase by 8 times. This rule also applies to tea.

Not on an empty stomach

This is the main rule of coffee lovers. Why is it harmful to drink coffee on an empty stomach? An invigorating drink drunk on an empty stomach will fill the body with additional acids, tannins, which will negatively affect the stomach. The habit of drinking coffee on an empty stomach can lead to irritation of the mucous membranes and the development of gastritis, ulcers, liver and pancreas problems.

Side effects and contraindications

Now about the unpleasant, but inevitable. Like any natural product, coffee has certain contraindications. As a rule, if the daily norm is observed, there are no side effects from drinking the drink.

Caffeine must have time to be eliminated from the body so as not to cause devastating health effects. Of course, everyone has a different metabolism, but it is recommended to stick to a dose of 4 cups of 150 ml daily.

Kafestol – what is it?

It is an organic compound similar in properties to cholesterol found in coffee beans. Once in the small intestine, it causes receptors to send an erroneous signal to the brain about a lack of cholesterol. In response, liver cells activate its production, as a result of which its level rises several times.

Naturally, people with high cholesterol levels are concerned about the question, is it not harmful to drink coffee every day? According to research by Dutch biologists, it all depends on how the drink is prepared. The longer it takes to cook, the more dangerous it will be for the body.

In natural black coffee

Kafestol is released from coffee fat when exposed to high temperatures. Espresso is the most popular coffee beverage and is brewed within minutes. This time is enough for the cafeestol to be in the cup.

It is estimated that 150 ml of espresso contains 15 mg of this substance. If you drink a couple of such cups a day, in a month cholesterol will rise by 7-10%. This also applies to piston coffee makers – in them, the cooking process is also quite long.

If you are preparing a drink in a Turk, try not to let it boil. In this sense, Turkish coffee on hot sand is ideal. It is clear that such technology is not available at home. Buy at least a Turk with a thick bottom and heat the drink over the slowest heat.

About green coffee

A new trend of our time is the appearance of green coffee on the shelves.

Unlike regular coffee, these beans are not roasted during production. It is believed that such coffee is healthier (contains antioxidants), has more pronounced stimulating properties. During frying, some of the substances are destroyed. Here they are preserved in the amount in which they were originally laid down by nature. But this is the ideal. In practice, in the production of instant green coffee, some of the substances are lost, since the technological process involves the use of elevated temperatures and pressures (powdered and granular coffee). Most of the nutrients are retained when making freeze-dried coffee. In this case, the decoction of the grains is frozen and dried under vacuum.

It is believed that green coffee contains less caffeine than roasted coffee. But this is not the case. Caffeine is an alkaloid. It remains practically unchanged during heat treatment (roasting). That is, how much of it was in green coffee, so much went into roasted coffee.

Green coffee does not have the usual coffee taste and aroma. Therefore, many manufacturers use all kinds of additives – they create both coffee mixes and various “fruit” drinks based on green coffee.

In green coffee

This is an independent variety, not a semi-finished product, and you do not need to fry it. It is completely ready to use and does not contain cafeestol. But it has a significant drawback – due to the lack of aroma, it seems less strong. Because of this, an overdose often occurs during its preparation. In fact, green coffee contains as much caffeine as traditional coffee beans.

In decaffeinated coffee

Decaffeinated beans contain cafeestol as well as “full-fledged.” Although caffeine is removed from them, the fat does not disappear. Therefore, under the influence of high temperatures, the same processes of cafeestol release occur.

About instant coffee

There is an ambiguous attitude towards this type of popular drink. Statistics show that 60% of consumers choose it. Fast, convenient and seemingly not harmful. To be honest, I belong to the 40% who don’t think so.

Most of the instant coffee on our market is freeze-dried. It is made from a mixture of coffee beans, roasted, ground and heat treated with hot water. Then the mixture is frozen, dehydrated, crushed and enriched with flavorings. Well, if natural.

But you cannot check this in any way, you can only hope for the good faith of the manufacturers. Plus preservatives, which are inevitably present in an instant product, since it is stored for a long time. The popular 3-in-1 drink options are especially suspicious in this regard. What is not shoved there – and flavor enhancers, and synthetic cream, and sugar substitutes.

And in the process of making instant coffee, a potentially dangerous compound is formed – acrylamide. It is a by-product of frying at high temperatures. In large quantities, it is capable of causing various pathologies of the nervous system and even provoking the growth of cancer cells.

Of course, this substance is also present in natural roasted grains, but in a much lower concentration. For comparison, instant coffee contains 358 μg / kg acrylamide, natural coffee – 179 μg / kg. It is believed that only excessive consumption of an instant drink can increase the risk of developing pathologies.

We are talking about a cup of concentrated coffee every 10 minutes – no one drinks that much. However, studies of the effect of this substance on the human body are ongoing. Perhaps new, more complete data will be available soon.

The harm from drinking coffee

The harmful properties of coffee are noticeably less, and they are not manifested in everyone: this requires certain contraindications. So what is the harm of coffee?

The first and most obvious disadvantage is that coffee affects the functioning of the nervous system. After a cup of coffee, a person is in a more agitated state, pulse and heart rate increase, blood pressure may increase;
Another disadvantage is that coffee is addictive. With frequent use, there may be a desire to increase the amount of coffee drunk, and if you refuse to drink, drowsiness, fatigue and a depressed mood appear;
If you drink more than three cups of coffee during the day, the body begins to poorly absorb the B vitamins. They are responsible for the smooth functioning of the central nervous system. In addition, the habit of drinking more than three cups of coffee every day affects the state of the human skeletal system. With this amount of caffeine, calcium is washed out of the body, which can cause osteoporosis and a decrease in bone strength;
Coffee is harmful when losing weight, because its excessive amount slows down metabolic processes. Drinking coffee releases the hormone cortisol, which can lead to insomnia. Lack of sleep slows down the weight loss process.
If you have extra pounds or obesity, the habit of drinking coffee every day can play a cruel joke on you. Caffeine contributes to the development of hypertensive hypertension, which, in turn, leads to strokes.
Caffeine has a negative effect on the functioning of the thyroid gland. Its smooth operation helps to strengthen the immune system. Therefore, if you do not want to constantly get sick with ARVI, give up the habit of drinking coffee often.
It is also known that coffee dehydrates the body as it has a strong diuretic effect. For this reason, doctors recommend drinking more plain water when drinking coffee.

Should you drink coffee every day?

Let’s return to our main question – is it harmful to drink coffee every day? First, and most importantly, you need to know about your state of health, and make sure that there are no contraindications, which we talked about in the previous chapter. If in doubt, be sure to consult your doctor, ask him directly about whether drinking coffee is harmful for you. Secondly, coffee must be ground or beans prepared by brewing. If we are talking about instant coffee, then drinking it every day is not advisable.

It is equally important to comply with the norm. There is nothing good about drinking 4-5 cups of coffee a day. This is harmful not only for the body, but also for the wallet, especially if you buy it in coffee shops. As for one or two cups a day, this is the most optimal rate that will not harm a person who has no contraindications, even if you use coffee. everyday.

By the way, if you add milk to coffee, the stimulating effect of drinking the drink decreases. But it’s a great way to minimize the harm from coffee for people who cannot refuse it at all.

Oncopathology

Analyzing the results of studies carried out in recent years, the staff of the University of Milan came to the conclusion that coffee does not cause cancer.

In fact, according to Italian scientists, this drink is even able to resist several types of cancer pathologies, including cancer of the oral cavity, liver, endometrium, prostate and colon.

Caffeine significantly increases physical performance

Caffeine stimulates the nervous system by causing it to send signals to fat cells.

However, caffeine also increases blood levels of epinephrine (adrenaline).

It is a fight-or-flight hormone that exists to make our bodies ready for intense physical activity.

Caffeine causes fat cells to break down fat deposits by releasing them into the bloodstream as free fatty acids.

Given these effects, it’s no surprise that caffeine improves physical performance by an average of 11-12%.

That is why it makes sense to have a strong cup of coffee half an hour before your workout.

Bottom Line: Caffeine increases adrenaline levels and frees fatty acids from adipose tissue. Plus, caffeine promotes physical activity.

Coffee boosts energy levels and makes you smarter

Coffee can help people feel less tired and increase their energy levels.

This is because coffee contains a powerful stimulant, caffeine, which is considered the most commonly consumed psychotropic substance in the world.

When you drink coffee, caffeine is absorbed into the bloodstream, from where it travels to the brain.
