Coffee is a drink made from the roasted grains of certain plant species. Its strength directly depends on the degree of their roasting. By the way, real coffee is a drink that was brewed in a Turk, prepared in a coffee machine, or poured with freshly ground boiling water. Instant coffee does not belong to the category of a noble drink, since due to prolonged processing, not only the strength, aromatic compounds, but also useful substances are lost.

Cons of coffee

Never drink coffee on an empty stomach. It promotes the production of a hormone such as cholecystokein, which triggers the digestion process. And if you haven’t eaten anything, then your stomach has nothing to digest. Hence: heartburn – gastritis – ulcer.

It also helps to increase blood pressure and sleep disturbances from coffee. And the preservatives that are present in coffee accelerate the appearance of cellulite, negatively affecting the metabolism (but in the form of a scrub, coffee is great).

If you are trying to wake up with this drink, then do not forget that in an hour after you drink it, your performance will increase. But after another hour, it will decrease, and you will feel sleepy.

But for pregnant women and nursing mothers, coffee is contraindicated, since caffeine can accumulate in the blood and reduce the level of iron and some minerals, which will negatively affect the child.

In addition, overuse of coffee can lead to dehydration. And it will not be easy for you to restore the water balance.

Pros of coffee

But not everything is so sad. This drink also has its advantages. Coffee contains antioxidants. By reducing the level of free radicals in the body, they slow down its aging, help in the fight against cancer, and reduce the risk of certain heart diseases, Parkinson’s disease and diabetes mellitus.

In addition, natural coffee helps to improve the functioning of the digestive tract. Helps with headaches, due to the expansion of the vessels of the brain.

Permissible storage period

What a pity to pour out a cup of cold coffee, which they did not have time to drink right away. The temptation is great to revive it – to bring it to a boil again. If no more than 5 hours have passed since the preparation time, there is nothing dangerous in this. Note that a sweet drink spoils faster.

If cooled espresso or Turkish coffee without milk and sugar is immediately put into the refrigerator, it can be reheated in a day. It is not recommended to store it longer. Yesterday’s black coffee,
warmed in the microwave or on the stove, contains as much caffeine as fresh coffee, so the invigorating effect will be fully manifested. But enjoying your favorite taste will not work.

After a while, coffee stops energizing you.

Many of us drink coffee every day for an additional boost of energy so that we can be even more alert and efficient during the day. However, our body develops a tolerance for caffeine, and we start to want to drink even more coffee. Like any excessive use, this sooner or later leads to side effects.

Caffeine overdose: myth debunked

The lethal dose of caffeine for a person is about 10 grams, this is 50 cups in a short period of time, how much it will not be easy to drink

The rule of the golden mean does not lose its relevance in the case of enjoying caffeinated products. Few people remain indifferent to their health and the issue of an overdose of coffee is all the more relevant, the higher its popularization in society.

But don’t panic. Even if you neglect the five-cup rule, trust me, overdosing is as difficult as swimming the Channel. A cup of coffee, depending on the degree of brewing, contains between 100 and 200 milligrams of caffeine. And the lethal dose for most people is about 10 grams. It turns out that in order to bring the body to the extreme, you will have to make a lot of effort and drink 50 cups of coffee in a short period of time. Most likely, the body will stop you on its own before it reaches the red line.

An overdose of coffee is more like a myth, although medicine does not deny an overdose of caffeine, but it is more the prerogative of pills or powder. Enjoy your favorite drink and do not be afraid of toxic effects, but remember that overuse of coffee is unhealthy.

Anxiety

Caffeine is known to increase alertness.

It works by blocking the action of adenosine, a brain chemical that makes you feel tired. At the same time, it triggers the release of adrenaline, the fight-or-flight hormone that is associated with increased energy.

However, at higher doses, these effects can become more pronounced, leading to anxiety and nervousness.

Excessively high daily intake of 1,000 mg or more per day causes nervousness and similar symptoms in most people, while even moderate consumption can lead to similar effects in caffeine-sensitive individuals.

In addition, moderate doses have been shown to induce rapid breathing and increase stress levels when taken in one dose.

One study in 25 healthy men found that those who took about 300 mg of caffeine experienced more than double the stress than those who took a placebo.

SUMMARY:

While low to moderate doses of caffeine can increase alertness, large amounts can lead to anxiety or irritability.

Insomnia

Caffeine’s ability to keep people awake is one of its most valuable qualities.

On the other hand, too much caffeine can make it difficult to get enough restorative sleep.

Studies have shown that increased consumption of caffeine increases the time it takes to fall asleep. It can also decrease overall sleep time, especially in the elderly.

In contrast, low to moderate amounts of caffeine do not appear to significantly affect sleep in people who are considered “good sleepers,” or even in people with insomnia.

You may not realize that too much caffeine is interfering with your sleep if you underestimate the amount of caffeine you take.

While coffee and tea are the most concentrated sources of caffeine, it can also be found in cocoa, energy drinks, and several types of medications.

It’s important to note that the amount of caffeine you can consume without affecting your sleep will depend on your genetics and other factors.

Studies have shown that although caffeine stays in your system for an average of five hours, the time frame can range from an hour and a half to nine hours, depending on the person.

One study looked at the effect of timing of caffeine intake on sleep. The researchers gave 12 healthy adults 400 mg of caffeine either six hours before bed, three hours before bed, or just before bed.

The time it took for all three groups to fall asleep and the time they spent awake at night increased significantly.

These results indicate that it is important to pay attention to both the amount and timing of your caffeine intake in order to optimize your sleep.

SUMMARY:

Caffeine can help you stay awake during the day, but it can negatively affect the quality and quantity of your sleep. Reduce your caffeine intake by midday to avoid sleep problems.

General deterioration in well-being

In addition to headaches, you will experience irritability, anxiety, dizziness, possible flu symptoms, insomnia, mood swings, and sluggishness. It sounds really scary, even looks like serious side effects of drug addiction. But do not worry, everything will be limited to only the first days without coffee.

Digestive problems

Many people find that a cup of coffee in the morning helps to get their bowels moving.

The laxative effect of coffee is associated with the release of gastrin, a hormone produced by the stomach that speeds up activity in the colon. What’s more, decaf coffee showed a similar response.

However, caffeine itself appears to also stimulate bowel movements by enhancing peristalsis, the contractions that move food through the digestive tract.

Given this effect, it’s no surprise that high doses of caffeine can lead to loose stools or even diarrhea in some people.

Although coffee has been thought to cause stomach ulcers for many years, a large study of over 8,000 people found no connection between the two.

Since coffee can have a significant impact on digestive function, you can cut back on the amount you drink or switch to tea if you have any problems.

SUMMARY:

While a small to moderate amount of coffee can improve bowel motility, large doses can lead to loose stools. Reducing coffee consumption or switching to tea can be beneficial.

High blood pressure

Overall, caffeine does not appear to increase the risk of heart disease or stroke in most people.

However, several studies have shown an increase in blood pressure due to its stimulating effect on the nervous system.

High blood pressure is a risk factor for heart attack and stroke, as it can damage arteries over time, restricting blood flow to the heart and brain.

Fortunately, the effects of caffeine on blood pressure seem to be temporary. In addition, it has a profound effect on people who are not used to using it.

High caffeine intake has also been shown to increase blood pressure during exercise in healthy people as well as in people with mildly high blood pressure.

Therefore, it is important to pay attention to the dosage and timing of your caffeine intake, especially if you already have high blood pressure.

SUMMARY:

Caffeine appears to increase blood pressure when consumed in high doses or before exercise, and in people who rarely drink it.

Addiction

For all the health benefits of caffeine, there is no denying that it can become a habit.

This can lead to psychological or physical dependence, especially at high dosages.

Moreover, the frequency of caffeine intake plays a role in addiction.

If you regularly drink a lot of coffee or other caffeinated beverages, there is a very good chance that you may become addicted to its effects.

SUMMARY:

Going without caffeine for several hours can lead to psychological or physical withdrawal symptoms in those who consume large amounts daily.

But what about cold coffee?

Do not confuse a cold drink with an initially cold drink. The increasingly popular cold brew (cold brewed coffee) is prepared for 12-24 hours, pouring cold water over the ground beans. But you can store it in the refrigerator for several days. At the same time, the beneficial properties, taste and smell do not disappear anywhere. This option can be prepared at once several servings and drunk even yesterday, even the day before yesterday.

Positive effects of avoiding coffee

The conversation about the tangible negative effect of caffeine on the body, as always, comes down to the concept of measure. If you can definitely describe yourself as an avid coffee lover and simply cannot live the day without a few servings of your favorite drink, then you should think about reducing the coffee you consume or even giving it up. You can feel the positive effect within 1-2 weeks after this decision.

Sleep normalization

It’s no secret that caffeine excites the nervous system when we are awake. He can do this during sleep, if taken in increased doses: for example, drinking more than three cups of coffee per day. And even if you do this 6 hours before bedtime, your biological cycle is likely to be disrupted.

With the complete exclusion of the drink from your menu, the body will not be overexcited, which in turn will affect sleep. First, you will fall asleep easier and more likely to forget what it is like to lie awake in bed for half an hour or more. By the way, coffee is generally contraindicated for people suffering from insomnia. Second, you’ll get better sleep, making it easier to get up in the morning. And as a bonus, you will simply look more refreshed, without any bruises under your eyes.

Stabilization of the emotional state

Of course, we are only talking about mood swings and increased irritability. As we said before, caffeine is a stimulant for our nervous system. Therefore, it is not surprising that when consumed in large quantities, feelings of dissatisfaction and irritation will accompany you throughout the day. The exclusion of an invigorating drink from the diet will lead to a stabilization of the emotional background, although for those who are really addicted to coffee, at first it will be quite difficult psychologically.

Energy boost

Despite the fact that most people drink coffee to cheer up or simply wake up, without it you will have much more energy. Caffeine causes the body to release adrenaline, which leads to a surge of energy. However, with the constant consumption of coffee, each time you need more and more stimulant for the body to respond to it with equal efficiency.

In addition, coffee can block cortisol, a hormone that is produced in the body during the day and helps to wake up in the morning and fall asleep in the evening. In the morning, the level of cortisol in the body is highest: it is usually produced from 6 to 9 in the morning, with a peak at 8-9 in the morning. Therefore, if you constantly drink coffee in the morning and block the hormone, the invigorating effect will be short-lived and the feeling of drowsiness will overtake you very soon.

Weight loss

Cortisol also affects the adrenal glands, which work in concert with the thyroid gland. The thyroid gland is an important organ that is also responsible for metabolism. Caffeine slows it down, and avoiding coffee, respectively, can help in losing weight.

Boost immunity

Continuing the conversation about the work of the thyroid gland, it is worth saying that excessive consumption of coffee in general limits its performance. This factor causes a weakening of the immune system and, consequently, many diseases. This is why eliminating caffeine when you are feeling unwell is beneficial. Drinking coffee is not worth it, at least until you feel better.

Normalization of the level of vitamins and nutrients

Coffee contains tannin, which interferes with the absorption of iron. A side effect of the drink, due to its diuretic properties, is also calcium leaching, which can lead to fragility of bones. Also, the level of potassium, zinc decreases, the water balance is disturbed and vitamins B, C and PP are neutralized. Thanks to the rejection of coffee and due attention to maintaining the level of vitamins and nutrients, their content in the body will return to normal. And the adjusted water balance will improve the skin condition: bruises under the eyes will disappear, blush will appear, and the look will become more fresh.

Improving liver function

Constant drinking of coffee can cause the effect of the so-called lazy liver. This organ produces enzymes that help break down harmful chemicals and metabolize them. Coffee also badly needs these processes, so the liver, figuratively speaking, after hard work can become lazy when it encounters other harmful substances.

Why is it better not to drink coffee right after waking up?

The key hormone produced by our bodies during the day is cortisol, which helps to wake up in the morning and fall asleep in the evening. In the morning, the level of the hormone is highest, and if you drink coffee at this time, the drink will block its production, which means that after a while we will want to sleep again. Usually, cortisol production occurs from 6 to 9 in the morning, and the peak occurs at 8-9 in the morning, so it is best to drink coffee at 10 a.m. or in the afternoon.

Coffee can cause tooth decay and staining

It only takes 1 cup of coffee a day for the natural color of your teeth to change and turn yellow. Depending on the quality of the coffee and the amount of sugar in it, it can also cause tooth decay. This usually happens if you drink syrup-flavored coffee drinks. The same thing happens with certain types of tea.

Active substance

Caffeine – one of the most active ingredients in coffee beans – has been identified by university researchers in Melbourne as one of the most common drugs of abuse.

The statements of Australian researchers are by no means groundless, since excessive and prolonged use of coffee can cause physical and mental dependence, and if the daily norm is exceeded, it can cause headaches, nausea and tinnitus. Drinking a lot of coffee is dangerous, but at the same time it can be of great benefit.

Who is coffee contraindicated for?

Well, now let’s move on to the most important part of our today’s research, namely, consider the contraindications for which drinking coffee is most harmful.

Obviously, people who have insomnia or have trouble sleeping should give up coffee. Especially harmful for insomnia coffee in the afternoon;
Patients with hypertension should give up coffee, because caffeine stimulates an increase in blood pressure;
People suffering from stomach ulcers and duodenal ulcers, gastritis should forget about the habit of drinking coffee forever. The drink is also harmful to those who have found increased acidity of gastric juice;
If a person has stones in the gallbladder or a blockage in his ducts, this product should also not be consumed;
It is harmful to drink coffee for smokers. Everyone knows that a smoked cigarette constricts blood vessels, but few people think that coffee has the same effect (especially on the vessels of the brain). As a result, the body receives a double load.
For people with neuroses and other mental disorders, coffee is not desirable. In such people, caffeine increases anxiety, eliminates the state of peace and tranquility. You can try decaf coffee, it is less harmful;
Pregnant women should give up the habit of drinking coffee every day. We have already talked about the reasons – coffee flushes calcium from the body, which can negatively affect the formation of bones;
Drinking coffee is also harmful for people suffering from cardiovascular diseases, especially with arrhythmias and hypertension. The reason is that coffee raises the heartbeat and constricts blood vessels, which aggravates the condition in the presence of these diseases.

If there is one or more contraindications, it is better to refuse coffee and replace it with a milder drink, for example, chicory. Cocoa is also a great alternative to coffee.

Early symptoms

Symptoms of a caffeine overdose are similar to those of poisoning. The heart begins to beat faster, trembling appears in the hands, a pressing sensation appears in the head, diarrhea and nausea may occur. Dry mouth and sweating are likewise critical signs.

Since the alkaloid is excreted from the body in 4-6 hours, after the peak of the discomfort, severe fatigue and exhaustion appear.

Late symptoms

The regular abuse of caffeine forms a persistent addiction. Its symptoms differ from classic poisoning and indicate rather a depletion of the central nervous system.

The first sign is the absolute uselessness of the drink: instead of cheerfulness, its use causes a feeling of fatigue, confusion of thoughts and a desire to drink another cup. Side signs can be loss of interest in everything around, lack of appetite and irritability.

Insomnia occurs due to a stable overload of the nervous system and excitation of the brain.

First aid

You need to provide an influx of fresh air: open a window, free your neck by unbuttoning your shirt or jacket. Next, try to flush the stomach in the classic way: drink a couple of glasses of salted water and induce vomiting. This must be done as quickly as possible, until the alkaloid is completely absorbed.

After that, it is necessary to take a sorbent: enterosgel, polyphepan or activated carbon in a dosage of one tablet per kilogram of a person’s weight. If the symptoms have subsided slightly, but tremors in the hands and weakness remain, then you need to eat a large meal.

Best suited:

hot hearty soup;
porridge or potatoes;
pasta with fatty dressing.

Prevention

In order to minimize the harmful effects of coffee on the body, it is not necessary to completely abandon it. There is no definite answer to the question whether it is harmful to drink coffee every day. This process is individual.

Prevention methods:

Establish an acceptable dose for yourself and do not exceed it. Let’s say that you limit yourself to one cup in the morning and the second at lunch. After 4 pm – do not consume invigorating liquids at all, including strong teas and energy drinks.
Arrange for yourself days without coffee, giving the body the opportunity to forget about its action and wean it.
Replace it with other invigorating hot drinks, but with a milder effect: weak tea, chicory, herbal teas. A good alternative is a decaffeinated drink made from coffee beans. The taste is no different from the original, but the negative effect is minimal.
Drink plenty of clean water and walk more in the fresh air. This will speed up metabolic processes and alkaloids will not linger and accumulate.

Critical signs of poisoning

One of the signs of critical poisoning is nausea and feeling short of breath.

Other important signs:

It seems to a person that he is suffocating, while there are pains in the stomach, tension in the areas of the head and chest.
Hands start to shake.
There is a frequent urge to urinate and, at the same time, severe dry mouth. This means that the body has begun to dramatically dehydrate.
Cases of loss of consciousness are not uncommon.

Alarming symptoms of a possible coffee overdose

Rapid heartbeat, the first sign of which can be reversed with caffeine intoxication

Remember that caffeine works on an individual basis. What is safe for a healthy, athletic person can be dangerous for a weakened body.

Do not neglect the information, perhaps it is you who, recognizing the symptoms of a caffeine overdose in time, will provide the necessary assistance to those in need.

Pay attention to:

Heart palpitations. Caffeine acts as a central nervous system stimulant, increasing the heart rate;
Trembling, anxiety. Caffeine stimulates the release of adrenaline, which causes unnecessary anxiety and nervous tremors;
Muscle cramps and spasms. Large doses of caffeine can cause muscle contractions, erratic movement, and seizures;
Diarrhea and increased urination. Caffeine dilates blood vessels and increases blood flow through the kidneys, making them more active in filtering waste products. Plus has a laxative effect on the intestines, why it causes diarrhea and spasms;
Headaches and hallucinations.
The combination of diuretic and stimulatory impulses through the body can overload receptors in the brain, leading to headaches.

Don’t Panic: A Few Secrets of Caffeine Detoxification

At the first symptoms of an overdose, you must drink plenty of water and go out into the fresh air.

Often, friendly gatherings over a cup of coffee are held in the cramped premises of the coffee shop, where there are a lot of people and there is a terrible lack of air. All this aggravates the effect of caffeine on the body and can lead to unpleasant consequences.

Having found the voiced symptoms in yourself or one of your friends, you cannot panic. Here are some simple tricks to neutralize the effects of caffeine and avoid the effects of an overdose:

When in a stuffy room, go outside. Walking in the fresh air will saturate the body with oxygen, restore the heart rate and relieve oppressive anxiety.
At the first symptoms of an overdose, you must drink plenty of fluids. Water will dilute the excess of caffeine that has been ingested and will help clear the body of decay products faster.
Eat a banana if you don’t feel nauseous. Citrus fresh is perfect. The high content of potassium and vitamin C will fill the deficiency of trace elements and return the heart to a healthy rhythm.
In a more serious case: numbness of the limbs, blue, loss of consciousness, call an ambulance without delay.

If you lose consciousness, you need to urgently call an ambulance

Treat your body with respect and avoid drinking too much coffee. Even if this was your norm before, keep in mind that in a state of illness, the body’s resistance decreases. Let the coffee ceremony continue to be associated with pleasant moments.

Few facts about instant coffee

Instant coffee is of lower quality than coffee beans.
It has the same positive and negative properties as grain. True, these properties are less pronounced.
To achieve a good taste, manufacturers add chemicals (stabilizers, antioxidants, dyes) to instant coffee. Coffee free from such additives is called organic.
In the process of growing coffee beans, it is not uncommon for coffee producers to use pesticides that end up in the beverage mug even after extraction to make instant coffee.

What to do if you drink a lot of coffee

The first signs of a caffeine overdose are severe tachycardia and dizziness that occurs after 5-10 minutes. after drinking coffee. The attack may be accompanied by a throbbing headache, nausea, a feeling of lack of air, tinnitus, blurred vision.

The first thing to do in such cases is to urgently rinse the stomach by drinking a few glasses of water. In case of an overdose of caffeine, there is no specific antidote, but the effect of the substance can be reduced:

drink a glass of non-alcoholic beer – hops reduce the stimulating effect of the alkaloid;
drink a glass of milk or non-acidic yogurt: calcium and casein interfere with the action of energy drinks;
drink plenty of fluids: caffeine dissolves quickly and is filtered by the kidneys.

When coffee is poisoned, fresh cool air is needed. In the room, you should open the windows, and when you feel good, take a walk down the street. If the condition has worsened seriously and intoxication has caused severe arrhythmias, medical attention is needed. Before the arrival of an ambulance with tachycardia, you can take 30 drops of Valocordin or Corvalol.

After removing caffeine from the body, it is forbidden to consume any products with its content for several days: coffee, cocoa, chocolate, cola, tea.

How to reduce the harmful effects of coffee on the body

If you suffer from hypertension, increased nervous excitability, choose decaf coffee. But you cannot get carried away with such coffee either, because the substances contained in it (including unexplored ones) can have a stimulating effect.
Do not drink coffee at night if you have insomnia.
If you have diabetes, drink weak coffee without sugar. But no more than 1-2 cups a day.
If the level of cholesterol in the blood is high, a tendency to atherosclerosis, diseases of the cardiovascular system, use paper filters in coffee makers. Reduce the frequency of drinking instant coffee, because it also contains cafeestol, which increases cholesterol levels.
If you have high acidity of the stomach, hyperacid gastritis, do not drink coffee on an empty stomach, try to avoid strong black coffee. After all, coffee will further increase the acidity of gastric juice, which can lead to ulceration. If you can’t deny yourself coffee, choose it with added milk.
If you are prone to obesity, do not add a lot of sugar, syrups, ice cream and a lot of milk to your coffee.
Be sure to observe the water and drinking regime to avoid pathological reactions of the body associated with dehydration.
To avoid the leaching of calcium and trace elements from the body, monitor the variety of your diet, do not neglect the use of dairy products.
If you are pregnant, it is better to deny yourself the use of coffee or reduce it to a few cups a month.
To be more confident in the benefits of the drink for your health, give preference to coffee beans (if there are no contraindications), rather than instant coffee. In this case, you can avoid the use of various flavors used in production. In addition, when buying coffee beans labeled “Eco”, you can be sure that both farmers and importers are trying to avoid the use of pesticides and pesticides all the way from the coffee tree to your coffee grinder.

A remedy for depression

Therefore, probably, coffee has become the second most widespread drink in the world – after water. Two-thirds of humanity consists of coffee lovers, and Russia, according to the International Coffee Organization, ranks seventh in the top ten countries – active consumers of the drink.

Of course, people value coffee primarily for its tonic effect. This is the merit of the main component – caffeine. Its influence was studied even in the laboratory of Academician I.P. Pavlov, and it turned out that it stimulates the processes of excitation in the cerebral cortex. And this, in turn, leads to an acceleration of metabolism and an increase in the vital activity of tissues.

However, the mood after a cup of coffee rises not only because of the cheerfulness that the drinker gains. It is also the result of exposure to serotonin. A couple of cups of coffee a day effectively reduces the risk of depression. People who regularly drink coffee are several times less likely to commit suicide than those who do not drink it.

Maximum allowable coffee rate

Anyone who cannot imagine his life without coffee thinks: how much can you drink your favorite drink so that it is not harmful? The maximum dose of caffeine for a healthy person is 300 mg per day (a cup of cappuccino, for example, contains 60-70 mg of caffeine). This is especially true in the summer, when solar activity is increased, and excessive consumption of caffeine can affect the work of the cardiovascular system.

If we talk about the dose, which is strictly forbidden to exceed, then this is about seven cups a day. Further addiction to caffeine can develop. You will need more and more coffee to meet your body’s needs. Drinking more than seven cups a day is harmful.

If you exceed the permissible maximum coffee, you can face unpleasant consequences, namely:

The human nervous system begins to work hard. You are constantly in a state of stress, the psyche is overloaded, which entails unfavorable consequences;
Addiction to coffee develops. A person reaches for another cup to feel cheerful and cheerful. He does not want to be depressed, therefore he constantly thinks about coffee. Mania develops. It’s unhealthy!
Coffee affects appetite. For those who like to drink a lot of coffee every day, it is usually reduced, there is a rapid weight loss, dehydration of the body;
There is a decrease in immunity. During the period of ARVI, a person is more at risk of getting sick, and getting sick cannot recover for a long time, since the body is exhausted;
The level of nervousness, depression, apathy, and a decrease in the emotional background increase. This is the ricochet effect that develops from excessive consumption of coffee;
Sleep disturbances are also a side effect of coffee consumption. Doctors believe that the last cup of coffee should be drunk before twelve o’clock in the afternoon;
The functions of the brain deteriorate, which refuses to work at full strength without the usual doping. He constantly needs recharge.

The well won’t help out

Coffee is from Kaffa. This was the name of a province in Ethiopia, where shepherds noticed the red fruits of an unknown tree, which were eagerly eaten by goats. Soon enough, people learned how to make a drink from these grains. And they realized that in the drink it is important not only the quality of the grains themselves, the degree of their grinding, but also the quality of the water. Indeed, most of the coffee consists of it: 98.5% – classically prepared and 85-96% – brewed in a coffee machine.

What kind of water is needed for good coffee?

Standing up – does not fit. The water should be fresh and, moreover, have a low level of mineralization, since the high salt content does not allow the taste and aroma to fully manifest themselves.

It is clear that the municipal water supply system is a poor helper. But even if you are a happy owner of a house with your own well and an individual water supply system, this does not mean that you can take what flows from the tap. There, as a rule, the water is mineralized, and in most regions of our country it is also hard, that is, saturated with calcium and magnesium salts – coffee pests that block taste and aroma. But this is not enough: they can themselves go into the drink, spoiling it with excessive bitterness.

Caffeine can raise blood pressure

Coffee causes a significant increase in blood pressure for a short period of time. For those who already have high blood pressure, drinking large amounts of coffee can have serious consequences.

What will change?

The brewed coffee the next day and even after a couple of hours will not contain essential oils, which give the drink a divine taste and aroma. Fats in any product, including coffee beans, are quickly oxidized. The cup will contain liquid that faintly resembles real coffee. You don’t have to be a gourmet or a professional barista to feel the difference between yesterday and the fresh.

There will be no nutrients left in the cup, but grains contain vitamins PP, B1, B2, calcium, potassium and magnesium.

Conclusion

Today coffee is one of the most widespread drinks in the world (second only to tea). And this is no coincidence, because coffee has a unique taste and amazing, alluring aroma. However, so that this wonderful drink does not harm you, you need to make sure that you have no contraindications, which we talked about today. If you have any doubts – feel free to go to the doctor, examine your body, and then you can enjoy this wonderful drink every day without worrying about your health!
