A large number of people can not imagine their morning without a fragrant cup of coffee, this tonic drink invigorates and energizes. There are many studies and opinions about coffee, the benefits and harms of the human body. Which ones are correct and is there a risk of harm to health by drinking every day?
Coffee is made from roasted coffee tree beans. In nature, there are more than 90 varieties of such plants. Of industrial varieties, Arabica and Robusta are most often used.
The composition of coffee beans contains more than one thousand different components, 800 of them are aromatic substances that give the drink a unique smell. Grains contain:
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 help eliminate toxins from the body. In addition, in the shell there is plant fiber and phenols that stimulate the gastrointestinal tract.
During roasting in grains, the water content decreases by 3 times. The calorie content of 1 cup of tonic drink is only 9 kcal, but if you add a little milk or dilute it with cream, the energy value of the product increases to 40-60 kcal.
How is coffee good for the body?
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.
According to the production method, instant coffee is powdered, sublimated or granulated. Powder is prepared from fried 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 of the powder is formed into granules using high pressure steam.
Sublimated product is prepared differently. First, make a decoction of coffee beans and completely freeze it, the resulting mass is dehydrated at low pressure. Then the product is crushed into small pieces of irregular shape. The sublimated variety, unlike other types of instant drink, maximally preserves the properties and taste of natural grains.
Useful and harmful properties of coffee in the form of powder or granules are manifested in a lower caffeine content, 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, and the central nervous system; increased acidity of the gastric juice affects liver function.
Freeze-dried coffee retains the same amount of caffeine as natural black coffee. It has the same effect on the body.
To add spice and variety to a popular drink, flavored varieties are produced with the taste of caramel, chocolate, vanilla, hazelnut, almond, honey, lemon, alcohol. Particularly famous was the flavored grain product.
Refined taste is given by spraying flavored substances (essential oils) onto grains, the inside of the package, into ground powder. What is the benefit of a flavored drink? The beneficial properties of coffee are the same as those of natural varieties. Just need to remember, a natural flavored product made from quality grains cannot be cheap.
Is coffee harmful to health? When taken correctly, a natural drink does no harm, and in some cases is even beneficial. Its systematic use of 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, tremor of the extremities appears, confused consciousness, headache.
Important! A safe daily dose of caffeine for a person 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 disturbed and death can occur!
Caffeine tones the nervous system, improves mood, improves performance. Therefore, it causes psycho-emotional addiction. A dependent person feels irritation, a headache without drinking coffee, his working capacity decreases, and drowsiness appears.
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 replenishes this trace element. The drink retains all the harmful and beneficial properties of natural coffee.
When milk is added to the drink, mineral salts of calcium are accumulated in the kidneys and stones are formed.
Natural coffee, the benefits and harms for women and men from its use is manifested in increasing the overall tone of the body. The negative impact of the drink causes disruption of the heart, liver, and nervous system. Blood circulation increases, which increases the load on the organs of the cardiovascular system. Increasing the acidity of the stomach after taking coffee increases the load on the liver.
Flavored coffee beans are ground and brewed in a Turk. Diluting the drink with cream or milk is not necessary so as not to spoil the taste of the additives. Sublimated or granular soluble product is brewed with boiling water. You can add 2 tablespoons of milk to reduce bitterness, and honey instead of sugar.
You can add a slice of lemon to any type of coffee, this will give the drink a special taste and aroma. Citrus zest, cloves, cinnamon are also used. A drink with lemon will help replenish the supply of vitamin C, potassium, phosphorus and magnesium, which is washed out by caffeine. Lemon has a beneficial effect on the state 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 sputum, and citrus strengthens the immune system, fights viruses and relieves inflammation. Honey is a powerful antioxidant, reduces the harm from drinking coffee.
To add to the tonic drink, it is best to use linden and buckwheat varieties of honey, they help reduce the bitterness of natural coffee. You need to prepare a drink with honey correctly, the bee product is added to a warm drink (50˚), otherwise all the useful properties of honey disappear.
What harm does coffee cause to the body:
What is harmful coffee for pregnant women? The drink dilates blood vessels and is able to increase blood pressure. This is dangerous for the health of the expectant mother, so involuntary abortion, bleeding or premature birth can occur. Dangerous dosage - more than 2 cups every day. With violations in the work of the heart and vascular system in the expectant mother, children can be born with a lack of body weight, anemia.
The harm to coffee for young women is to reduce the ability to conceive a baby by 40%. This happens because caffeine changes the hormonal background, negatively affects ovulation and the contractility of the fallopian tubes.
For pregnant and lactating women, the harm of coffee is the negative effect of caffeine on the baby’s nervous system. Due to the diuretic properties, calcium is washed out, the baby's teeth will deteriorate quickly, and the mother will lose permanent ones.
Important! With the frequent use of coffee, women need to make up for the loss of fluid in the body. Drink at least 2 liters per day of clean still water.
The systematic use of a soluble freeze-dried product without constant physical exertion leads to the formation of cellulite in women on the hips and abdomen. The drink disrupts the blood flow, contributes to the violation of water metabolism, and these are the main causes of the formation of the "orange peel".
What is the harm of coffee for men? When using a flavored drink, the level of testosterone in the blood of the stronger sex is reduced. With urine, trace elements necessary for the work of the prostate gland (magnesium, zinc, vitamins A, E) are excreted, sexual desire is reduced.
Caffeine stimulates the production of stress hormone and the release of adrenaline into the blood. The male body perceives this as a decrease in the need for testosterone.
The harm to coffee for the male body is the risk of developing enuresis (urinary incontinence). American scientists have found that drinking a natural drink of 3 cups per day by 70% increases the possibility of urinary incontinence.
The main contraindications:
In case of an overdose, the harm of coffee is manifested in the occurrence of insomnia, nausea, vomiting, dizziness. Excitation of the central nervous system occurs, tremor of the extremities, confusion, migraine may appear. The heartbeat is becoming more frequent, the rhythm of its work is disrupted, blood pressure rises.
Is coffee good for human health? With proper use and the absence of contraindications, a flavored, black or sublimated drink will give vigor, increase working capacity and mood. And the addition of lemon and honey will help reduce the negative effects of caffeine.

A little less than 3 billion cups of coffee are drunk daily in the world ( and this number is growing steadily)! Of course, such popularity is primarily due to the magical aroma and invigorating effect of the drink, but it also has a direct effect on the body. But what kind of impact is this, positive or negative, let's try to understand this very detailed article.
In the media quite often there are reports of the benefits or dangers of coffee. And often this news contradicts each other. I tried to summarize the latest research in this area. If you are a lover of this wonderful drink, then it will be useful for you to know what the benefits and harms of coffee are, how much it can be drunk per day, and what time is better, and I will regularly update this article if new scientific information appears.
I'll run a little ahead ( or as it’s fashionable to say now, I’ll allow myself a small “spoiler”) and I will delight the coffee lovers: almost all studies on the effect of coffee on a person come to the same general result - this wonderful drink has more beneficial properties than harmful ones, but still there are negative aspects, so we'll talk about them in the article. In general, I honestly tried to make the material as objective and comprehensive as possible, I hope that it worked out.
All the facts listed in the article are taken from the media, and not from the “yellow” orientation, but from completely respected and authoritative ones. Each news about the properties of coffee is also published in the section of the blog "Interesting News" with an indication of the source.
21. In medicine, caffeine is used to treat diseases that depress the central nervous system.The coffee component helps in case of poisoning with a drug or poison, with infectious diseases, with cardiovascular insufficiency, with vascular spasms.
23. It will help to find a slim figure. Chinese researchers found that coffee promotes the production of oxytocin in the body, which in turn reduces appetite and increases energy expenditure. As a result, due to the normalization of weight, we get a more slender figure ( the dream of many people - and eat and lose weight!) Another Chinese group of scientists from the University of Science and Technology in Guangzhou recommends for those who want to lose weight to drink 4 cups of coffee a day, the effect of a drink drunk 30 minutes before the workout will enhance the effect ( but no later than 16:00) An even more amazing result was obtained at the University of Arizona ( USA), you won’t believe it, but it turned out that adding to coffee ... oil helps to reduce weight ( since the fat added to coffee helps speed up the metabolism)! It’s only important to observe a few rules: add no more than 10 grams of butter, no sugar to a cup of coffee and drink such an unusual mix only in the morning. ( Although scientists say that it doesn’t matter what kind of vegetable or animal fat added to the drink, it seems that coffee with butter will be quite good, for example, in Singapore this option has been popular for a long time, and now the whole company actively promoting its version of coffee with butter “Bulletproof Coffee”).
24. Coffee for asthmatics. American and Italian researchers claim that drinking a couple of cups of coffee a day can 25% reduce the likelihood of asthma, and also significantly helps those who are sick.
25. Procreation.There are data obtained by Chinese scientists from the Classical University of Central China ( in Huazhong) that caffeine may increase the chance of getting pregnant!
26. Long life. Perhaps this is the most interesting item on our list and scientific research on this topic has been done quite a lot! The results of a large study conducted by Stanford University staff are very optimistic: coffee not only strengthens blood vessels, but also prolongs life, successfully combating metabolites that are sources of chronic inflammation and mortality. And at Imperial College London, scientists also obtained similar data from an even larger 16-year study in ten different European countries. Imperial College Londoners say a cup of coffee a day extends life significantly (preventing a whole range of possible ailments and reducing the risk of premature death from various diseases by as much as 12% ) And three cups and more increased the chances of staying healthy for many years ( unfortunately, British scientists did not name the upper limit on the amount of coffee consumed per day) Moreover, it doesn’t matter whether the drink is caffeinated or not, since polyphenols and antioxidants, which have a positive effect, are found in both types of coffee. Here is another interesting example: Spanish scientists over a very long period of time monitored the health of 20,000 volunteers and concluded that those who consumed 4 cups of coffee per day mortality risk was 64% lessthan those who did not drink coffee!
As you can see, coffee has a lot of advantages! But, as they say, the coin has two sides, so let's move on to the minuses, which are not many, but they still exist, and you need to know about them.
How much can I drink coffee per day ?
Summarizing the mass of various articles and news about the health hazards of coffee, which, as I have already said, is several times less than the information about its beneficial properties, we can draw the following conclusion: coffee does not cause absolute harm to health, IF THE MEASURE IS COMPLIANCE. The most ambitious work on this issue was carried out at the University of Edinburgh, where they analyzed and generalized the results of all existing studies and found out that the most optimal daily dose is 3-4 cups of coffee. The same conclusion was reached by their colleagues from the University of Southampton, who studied the findings of more than two hundred works on the benefits of coffee and found that drinking 3-4 cups a day gives a positive effect, it is with this volume that the coffee lover will get the maximum benefit from your favorite drink , and does not harm health.
A reasonable question arises - how much is this in the usual metric volume? Agree that the concept of " a cup"Very vague. I had to rummage around a bit in foreign sources to find the answer, since Russian recommendations on this score do not give any specific figures. Yes, and 99% of studies of the properties of coffee are conducted in Western countries, and most of them in the United States.
So here’s the result: the concept of “ a cup of coffee"There is most often called so" cup of regular coffee", or " an 8-ounce cup of regular brewed coffee", or like this " an 8-ounce freshly brewed cup". That is, we are talking about a cup of ordinary freshly brewed coffee with a volume of 8 ounces, which is approximately equal to 240 milliliters ( for pedantic readers, here's the exact value - 236.588248 ml.) The European version of "coffee cup" is approximately 250 milliliters, that is, comparable with the American version, therefore, we get the following picture: you can drink 3-4 cups of coffee per day, with a volume of 240-250 ml.
But it is much more important to know the amount of the main active ingredient - caffeine! The most authoritative organizations that have conducted serious research on this issue ( e.g. US Food and Drug Administration - USFDA and US Department of Agriculture - USDA) claim that a safe daily dose of caffeine for an adult is 400 milligrams, and it is highly recommended not to use more than 600 mg. per day. The difference depends on the individual characteristics of the body, but we will consider the average value suitable for most people. So, we try to adhere to the recommendation of 400 mg. And if you like accurate calculations, you can use this formula: for one kilogram of your weight per day, 6 milligrams of caffeine can be consumed without harm ( for me, for example, it is very close to 400 mg.).
If you prefer other options of coffee, rather than a standard cup of ordinary freshly brewed drink, then it is clear that you need to focus not on volume, but on the content of caffeine. Here, one caveat must be made right away - there are no absolutely exact, standardized parameters, even one type of drink, prepared in one institution, may contain different amounts of caffeine on different days. Here the role is played by the type of coffee selected, the amount of raw materials used for the drink, even the degree of roasting ( the last factor does not affect much, but still ...) Thus, in the standard cup already known to us ( 8-ounce cup of regular brewed coffee) may be from 70 to 100 mg. caffeine, in espresso 40–75, but for convenience there are some generally accepted average values \u200b\u200bthat can be found in this table:
Once again, we draw your attention to the fact that the individual daily rate of coffee depends on the features. So we recommend that you focus on the above data, but listen carefully to your body, if you feel great after just one cup, then it’s better to stop there. And if even after three cups you can safely fall asleep ( there are such talents), then you do not have to go to the other extreme - the absorption of coffee in huge volumes. It is very important to remember that with all the variety of useful properties, coffee ( like absolutely any, even the most useful product) in excessively large quantities can be harmful, so do not abuse this drink! Be aware that the average dose of caffeine that can be fatal is between 150 and 200 milligrams per kg. your weight ( these are more than 70 standard cups) and that caffeine also enters the body from other sources - tea, energy, and other drinks.
For the sake of an objective review, it is necessary to mention that periodically there are research results that reveal the minuses of coffee. Here in a special risk group are representatives of the beautiful half of humanity.
1. For example, there is a version that coffee in an amount greater than three cups per day can reduce female breasts. The truth is insignificant and not fast, but still ...
2. A study by the American University of Duke revealed that caffeine can seriously aggravate the painful symptoms of PMS, so women are advised to refrain from consuming too much coffee and other caffeinated products (such as chocolate).
3. In addition, drinking more than four cups of coffee per day can harm the bladder of women. This conclusion was made by an international group from the USA and Great Britain ( however, the same report mentions that if the dose is not exceeded, then the drink will improve the female body!).
4. Drinking coffee during pregnancy increases the risk of premature birth and even the possibility of miscarriage ...
5. The positive effect on the heart of moderate coffee consumption is mentioned in the first part of the article, BUT if you abuse a drink with cream and a lot of sugar, the substance "cafestol" contained in coffee will contribute to the accumulation of so-called "bad" cholesterol, which can easily lead to atherosclerosis, angina pectoris, heart attack ( in any case, it was precisely these conclusions that came to Harvard School of Health and the University of South Carolina) If you really can’t refuse to add delicious fat cream to your invigorating drink, then experts recommend drinking filtered coffee, that is, use coffee machines, drip-type teapots with filters, etc. ( my favorite way of brewing for the lazy is the French press, alas, this list is not included).
6. In older people, especially women, coffee can easily lead to increased fragility of bones. The fact is that due to age-related changes in the body, a drop in the level of calcium begins, which leads to osteoparosis (a decrease in bone density), and coffee additionally leaches this macronutrient. So with age, the amount of coffee consumed must be very strictly controlled and it is imperative to take vitamin-mineral complexes.
7. People with a tendency to vision problems should approach coffee drinking very carefully. The fact is that even a moderate amount can increase intraocular pressure, as a result, vision becomes worse and glaucoma may develop. The risk of getting such serious problems increases dramatically if you drink more than three cups of coffee during the day ( Brigham Young University, USA).
8. Coffee affects different consumers in different ways, people under pressure of stress, systematically lacking sleep should be especially careful, because excessive drinking of coffee can lead to depletion of nerve cells and, as a result, to problems with the nervous system. Also, an extra cup of coffee will no longer invigorate, but, on the contrary, will reduce efficiency. And in some cases, coffee can lead to spasm of cerebral vessels with subsequent oxygen starvation. Such a situation is fraught not only with migraine, but also a fatal outcome is possible ...
9. You may have a psychophysical dependence on coffee. This, of course, is not narcotic bondage, but still an addiction. Be careful, listen carefully to your body.
10. It must be taken into account that when roasting beans in coffee, acrylamide is formed. This substance, in principle, appears in the process of fat of any plant food, but it is dangerous because it can provoke the development of cancer in high concentrations. But, perhaps, you should not worry so much, because the amount of acrylamide should be simply gigantic, you certainly won’t get such doses from the drink. And if you look at the first part of the article, it turns out that in moderation, coffee protects against cancer.
So, when preparing the material, I was convinced that coffee has a huge amount of beneficial properties if you drink it within reasonable limits.And all the possible harm, as a rule, is associated with excessive consumption and only certain categories of people should refuse coffee altogether, this is the next point.
So, if you are a healthy person, take reasonable amount of coffeedrink it in the morning after eatingthen from this wonderful drink you will receive only benefit! More specific recommendations on the best time of the day for drinking coffee are given by a nutritionist: this is from 10:00 to 12:00(according to other sources - from 9:30 to 11:30, which is approximately the same range) This is explained by the fact that in the morning the body produces the most cortisol, which independently increases a person’s tone. At this time, the use of caffeine will be completely redundant. But when the amount of the hormone begins to decline, a cup of aromatic coffee will fully show its tonic properties.
I remind you once again that this article is “live”, that is, I periodically add new pros and cons of coffee to the lists if any fresh scientific data appears. So, dear coffee lovers, do not forget to look at this material from time to time to be aware of all the advantages or disadvantages of your favorite drink.
Many modern people can no longer imagine their life without coffee. An invigorating drink helps to wake up in the morning, raises pressure, gives vigor. And coffee lovers with a cigarette do not even know how to start their day differently. However, many do not understand that a drug can do some harm. The positive and negative qualities of coffee are studied along and across, so we will consider them in order.
The influence of the drink on the human body stems from the chemical list of coffee elements. In order not to be unfounded, we’ll talk about everything in detail.
Raw coffee beans include carbohydrates, fats, proteins. Also included are alkaloid compounds such as caffeine and trigonellin. Of the organic acids, oxalic, quinic, chlorogenic, coffee and citric are considered the most valuable.
The grain is not deprived of mineral salts, tannins, essential oils, water, vitamins, macro- and microelements. Of the latter, iron, potassium, nitrogen, phosphorus, and calcium are worth highlighting.
After roasting in grains, new elements are formed, for example, vitamin PP. The final chemical list of elements depends on the degree of roasting and the type of coffee.
It should be noted that the positive properties of the drink for the human body become possible only if coffee is dosed.
Addiction
Pathology of the cardiovascular system
High blood pressure
Poor calcium absorption
Irritability and nervousness
Development of oncology
Dehydration
Remember, drinking coffee before bed can play a trick on you. You can not only fall asleep, but also cause serious stress to the body. Increased irritability and nervousness will appear. It is also worth limiting the consumption of the drink to the elderly.
Dedicated to coffee lovers. Drink is beneficial for your body, but in everything you must follow the measure. Calculate your own permissible consumption rate, do not exceed it. Remember the possible consequences that occur when drinking coffee.
According to scientists, not everyone can drink coffee. People prone to sleep disturbances, nervousness and depression, as well as suffering from kidney disease, hemorrhoids, atherosclerosis, coronary heart disease should refrain from drinking a coffee drink. It is known that coffee adversely affects the functioning of the heart and can even cause hypertension in people who are predisposed to such diseases.
Also, this drink has a harmful effect on. Its use in the future leads to an increased risk of miscarriage. A coffee drink affects the formation of the nervous system, skeleton and other organs of the baby. Excessive consumption of coffee prevents the absorption of calcium, magnesium, sodium, which is fraught with the development of osteoporosis.
It is undesirable to drink coffee for those people who have problems with the gastrointestinal tract (gastritis, high acidity). Otherwise, it can be very serious, up to the appearance of peptic ulcer of the stomach. Elderly people and under 15 years of age are also not recommended to use this drink.
This aromatic and tasty drink improves metabolism in the body, which leads to an increase in the rate of fat burning. Accordingly, coffee is good for people who are overweight and want to be in perfect shape.
Chocolate is also an alternative to coffee. Such a coffee substitute can increase the level of energy and give a comfortable feeling. A good substitute for coffee is green tea. The advantage of this drink is that it contains many antioxidants that help protect people from free radicals and cancer.
It is hard to overestimate how popular coffee has become. Many simply cannot imagine a successful start to the day without a cup of this aromatic invigorating drink. Someone likes to brew it in a Turk, someone bought an expensive coffee machine, others prefer to drink an instant drink. Now you can find coffee of various varieties and degrees of roasting. In coffee houses you can easily find coffee with syrup, ice cream or spices, cream or milk. Have you thought about whether drinking coffee is harmful or healthy?
Is drinking coffee good or bad? There are a lot of myths around this topic. We tried to figure out where the truth is, and where only unconfirmed speculation. Let’s begin to understand all the advantages and disadvantages of coffee. We’ll immediately clarify that we use confirmed scientific data and the results of recent studies. But the opinions of scientists are quite contradictory. Some believe that the use of coffee is a powerful argument for drinking it in moderation (3-4 cups per day). Others believe that the harm from coffee covers all its beneficial properties. It was previously believed that coffee is able to negatively affect the body due to the high dose of caffeine that it contains. It was even believed that it could provoke the development of cancer of the intestine and other parts of the digestive tract. Now these arguments have moved to the myths section. Recent studies of how coffee affects the body have only confirmed its benefits. Coffee is especially useful for the digestive tract, in particular the intestines. It normalizes peristalsis. Also, coffee is able to speed up the metabolism. Thanks to this ability, under the influence of coffee, the mucous membrane of the intestinal walls and other organs are renewed.
It should also be borne in mind that the reaction to coffee in each person can be individual. For someone, this drink only benefits, and for someone it can even provoke the development of allergic reactions. Why is there such a controversial reaction? It is explained by the fact that the composition of coffee includes a huge amount of active substances. This is about a thousand different components. Of course, our body can perceive them differently. Much more depends on the strength of the coffee, the degree of its roasting, freshness. Most of the components that make up coffee have not yet been studied.
The beneficial properties that coffee has are undeniable:
Is coffee harmful to health? We have listed the main beneficial properties of coffee, which have long been scientifically proven. But do not forget that coffee can harm our body. Excessive coffee is most likely to be harmful. We are talking about exceeding the recommended dose of coffee (3-4 cups per day). It is also important to remember that there are people who are prone to individual intolerance to those components that make up coffee, especially caffeine. So, what can harm coffee.
We offer you some important facts that you will find it useful to know about this popular drink.
Recently, the popularity of green coffee is growing. What is he like? Why is it called green? What properties does it have? This type of coffee is increasingly appearing on store shelves. It is believed that it helps to get rid of extra pounds and remove toxins from the body. In fact, green coffee is just unroasted grains of regular coffee. Previously, it was considered raw material and did not go on sale. Now it is bought more and more often. It is generally accepted that green coffee has more pronounced antioxidant and stimulant properties. During roasting, indeed, part of the beneficial substances of coffee is destroyed, therefore, roasted coffee loses a little in its beneficial qualities. But in green coffee, all the beneficial substances are stored in maximum concentration. However, often in the production of green coffee, some of the useful qualities were lost. Despite the fact that this coffee is not roasted, it is still exposed to high temperatures. And if we are talking about the production of powder or granulated coffee, then it is also exposed to high pressure. A lot of useful components are stored in freeze-dried coffee. In this case, a decoction of the grains is made, then it is frozen and dried in a vacuum.
Is it true that green coffee contains significantly less caffeine? This supposedly differs greatly from green coffee. This is actually a myth. Caffeine belongs to the group of alkaloids. Heat treatment practically does not affect its condition and concentration. There will be as much caffeine in roasted coffee as in green.
Green coffee does not have the usual aroma and taste. This encourages manufacturers to resort to some tricks. Often other substances are added to green coffee. This is how drinks are made using green coffee. Most often, manufacturers simply add fruit flavors and call their product a fruit drink.
As you can see, despite all the benefits, coffee has a negative effect. Can it be reduced? Sure you may. To do this, you need to use such simple secrets.
As we have already found out, most of the negative properties of coffee are connected precisely with the presence of caffeine in it. It turns out that in order for this drink to bring only benefit, it is enough to exclude this component from it? Decaffeinated coffee is really for sale and it has its fans. But is it so safe? How useful is it?
We studied in detail how caffeine-free coffee is made. Forced to upset his supporters. This type of coffee is not at all as useful and safe as it seems to us. For. To obtain a caffeine-free product, this substance is literally washed out of coffee powder. For this, special chemicals are used. Moreover, this process is repeated several times, since it is not so easy to get rid of such a stable alkaloid. The result is a product of dubious quality, in which a certain portion of caffeine is still present. But during this technological process, aromatic oils, useful minerals, etc. are easily lost from coffee.
So, let's find out exactly what is more in our favorite invigorating drink! Is it more useful than harmful, or vice versa? In fact, as the results of scientific research say, a lot depends on the dose of coffee that we are used to getting. Scientists have found that 2-3 cups of strong coffee per day are relatively safe. If you do not exceed this amount, you most likely will not encounter its negative manifestations. With such an amount of the drink you drink, you will only be invigorated, fill your body with energy, improve metabolism, and get a stimulating effect on the central nervous system, brain, cardiovascular system and gastrointestinal tract. If the dose is exceeded, then the negative effect of coffee on the body will increase. In addition, people with hypersensitivity to the components of this drink eat. They should choose a safe dosage individually.
The tolerance of the drink is also affected by the genetic predisposition and general health. It is undesirable to drink a lot of coffee to people who:
In this case, it is better to refuse coffee at all.
Some advice on that. How to reduce the harm from coffee:
The result we got is that coffee can be beneficial and harmful. The main thing - do not abuse this drink! In reasonable quantities, it will really be useful for your body.
