Today there is great amount various coffee blends with original taste and aroma, plenty original recipes making coffee, there is even decaffeinated coffee or with special medicinal additives. But we will talk about useful and harmful properties himself regular coffee

– natural or instant, and whether it should be consumed and in what quantities. Many legends and gossip have long revolved around coffee. It is either considered a panacea for all ills, or declared and recommend limiting consumption. And practical experience in drinking this drink, as well as medical research, prove that everything here depends on the amount of coffee, the method of its preparation and the patient’s health condition.

Coffee composition

The impact of coffee on human health is explained by its chemical composition. IN coffee bean You can find a variety of substances, including the well-known caffeine and protein, as well as trigonelline, chlorogenic acid, and various mineral salts.

The listed substances account for approximately 25% of the weight of raw coffee beans, and the rest is fiber, oil and water. It should be borne in mind that the amount of these substances and their combination depends on the type of coffee. Caffeine is the most famous substance in coffee. It is caffeine that regulates and enhances excitation processes in the brain. If you choose an adequate dose of caffeine, it will help increase mental activity

, performance, and also relieve fatigue and drowsiness. But systematic use of large doses of caffeine can lead to addiction and exhaustion of the nervous system. Very large doses of caffeine can even cause death in the patient. Another important component of coffee is trigonelin.

This is a substance that is involved in creating the unique aroma of coffee; in addition, during roasting it turns into nicotinic acid; a lack of bark provokes the disease pellagra. An important component of coffee is chlorogenic acid. found only in raw coffee beans

. When roasted, it breaks down and produces other organic substances that give coffee its characteristic astringent flavor. Other acids in coffee, such as malic, citric, acetic and caffeic, help normalize the activity of the gastrointestinal tract and improve digestion. Bitterness in coffee is a consequence of the presence of tannins in it. . Tannins are complex organic substances with wide range actions, but under the influence of dairy products they disintegrate, so coffee with milk loses its bitterness. In addition, coffee contains up to 20% daily value vitamin P, which has the property of strengthening blood vessels, and useful minerals

, such as potassium, calcium, phosphorus and iron.

Negative effects of coffee on the body About the fact that coffee is not the best healthy drink , everyone knows. Doctors strongly recommend not to exceed the recommended doses of its use. This drink is addictive, so often when such symptoms occur, withdrawal does not bring relief. A vicious circle is formed, from which it is not easy to get out.

When drinking coffee, you need to remember that This drink has a pronounced diuretic effect. This negatively affects not only the functioning of the kidneys and ureter, but also the entire body, which begins to lack moisture. Therefore, in parallel with drinking coffee, it is important to drink other liquids.

A lot of talk revolves around the negative impact of coffee on heart function. But in reality this influence is too small to be taken seriously. Coffee increases blood pressure, but only for a short time and can only harm a person who already has serious heart problems.

Much more serious Negative influence coffee on the stomach. After drinking this drink, the acidity in the stomach increases, which can cause heartburn, as well as the development of gastritis and ulcers. It is especially dangerous to drink coffee on an empty stomach and with a cigarette, as is often done. To minimize the harm from drinking coffee, simply eat before drinking it.

Losing weight with coffee

Many of us are familiar with the fact that coffee helps to break up with extra pounds. Of course, this rule does not apply to cases where half the cake is washed down with coffee. But even for amateurs culinary masterpieces coffee will help, as it helps speed up metabolism and part with some extra calories very fast. In addition, coffee is an antioxidant and helps renew and rejuvenate the body's cells.

Those who want to lose weight with coffee should avoid sweet drinks, as well as coffee with cream and desserts. If black coffee seems unpalatable, you can add a little sweetener and skim milk powder.

Which coffee to choose - ground or instant (Video: “Is there instant coffee?”)

Every coffee lover can name more than one argument in favor of the fact that his favorite variety is the most best coffee in the world. But this, of course, is a matter of taste. But the debate about which coffee is better to choose, ground or instant, still has no end in sight.

Certainly, the content of nutrients in natural coffee is much higher. For example, natural ground coffee has a very high content of fatty acids, which prevent the formation of cancer cells. In instant coffee their amount is much lower. Also, ground coffee contains much more vitamins, as well as potassium and magnesium, which makes it even beneficial for the cardiovascular system. Of course we are talking about healthy person and moderate consumption of this drink.

What can we say about the content of harmful substances in natural and instant coffee? Instant coffee is the leader here, since its production requires complex chemical processes, as a result of which some harmful substances enter the composition. finished product. And to make natural coffee, you just need to grind the beans, their composition does not change.

The caffeine content is approximately the same in natural coffee and instant coffee. therefore, this criterion does not allow identifying a leader. But if you want to get decaffeinated coffee, you will have to use instant coffee. Also instant coffee contains fewer calories. If you want to lose weight by drinking coffee, it is better to give preference to instant coffee.

Coffee is loved all over the world. Quite a lot of fans invigorating drink and in our country. They can’t imagine the morning without a scalding cup aromatic coffee, they drink it in the afternoon to cheer up, and sometimes in the evening if they need to work late.

Opponents of the drink, and there are some, claim that coffee is harmful to health, that it increases blood pressure, negatively affects the nervous system, and, in addition, can provoke the development of cardiovascular diseases, and even causes cancer.

Are these warnings and fears true? Is the drink beloved by many harmful? Recently, a lot of research has been carried out on its effects on the human body.

Therefore, it is already possible to draw certain conclusions and dispel established myths. Let's find out some research results and draw our own conclusions from them:

Is instant coffee natural?

Many people are sure that instant coffee is pure chemistry. But this is not so (unless we are talking about counterfeits and forgeries). Instant coffee It is made from natural coffee beans, which are pre-ground and extracted. This is a product very similar to thick coffee, which was cooked in a Turk. Then it is dried. To obtain a powdered or granular product, it is processed by spray drying. If you need to get freeze-dried coffee, prepare it by cold drying at low temperature.

Effect on brain activity

The caffeine it contains undoubtedly has a stimulating effect on the nervous system and has a tonic and invigorating effect. After 20 minutes after drinking a cup, a person feels a surge of strength, his reaction improves, and his brain works more actively. This effect lasts from half an hour to several hours, then subsides.

It has been observed that moderate consumption of black coffee (1-2 cups per day) significantly reduces the risk of developing Parkinson's disease and Alzheimer's disease.

Coffee and blood pressure

It must be said that immediately after drinking a portion of a strong drink, the pressure rises slightly. However, this is observed in those who rarely drink it or in people suffering from hypertension. If a person is healthy, does not abuse strong coffee, the drink will not affect blood pressure in any way.

Can it harm the liver?

There is such a widespread opinion. But I must say that natural, not very Reviver not only does not destroy the liver, but protects it, providing a hepatoprotective effect. Thus, it protects the organ from the development of cirrhosis, and in addition, slows down the occurrence and growth of deposits and stones in the gall bladder.

Heart, blood vessels, oncology

The assumption that coffee contributes to the development of cardiovascular diseases and provokes cancer arose due to the presence of carcinogens in it. Indeed, when roasting over fire coffee beans, they release carcinogenic substances. However, for them to cause the development of the disease, greater concentration is required. But with normal, average consumption of the drink, the concentration of these substances is very insignificant, so they cannot cause any harm to a person.

Does coffee prevent depression?

This is true. The thing is that it contains serotonin, known as the hormone of joy. Its presence makes the drink an effective antidepressant. Just a couple of small cups a day can prevent the development of depression.

According to many experts who have conducted research, lovers of this drink feel confident in life, feel better, rarely experience unreasonable fear and do not suffer from low self-esteem.

What else is healthy about this drink?

Everyone knows that the drink contains caffeine. But many people consider it harmful, so they try not to drink coffee at all. However, doctors say that this substance in small doses is simply necessary for humans. If the body does not receive products that contain caffeine, including chocolate and tea, then the person will suffer from headaches and excessive irritability.

To prevent this from happening, a person just needs to drink 2 small cups of black coffee, or eat half a standard bar of natural dark chocolate.

In addition to caffeine, coffee contains about 30 extremely needed by the body human organic acids. It also contains vitamin P, which has beneficial influence on blood vessels. It also contains others useful material. The drink contains antioxidants that help maintain youthful skin and also reduce the risk of developing cardiovascular diseases.

Drinking a cup of an invigorating drink will do a person more good than harm. Of course, if you drink it in moderation. It will relieve fatigue, increase performance, and improve mood.

So drink your favorite drink, but remember that everything must be done in moderation. Therefore, 2-3 cups of coffee will not harm you, on the contrary, they will benefit you and give you pleasure from drinking. Be healthy!

Today, coffee is the most popular drink among people. I think almost every one of us drinks coffee at breakfast, and some cannot live without it and drink it in large quantities. Is drinking coffee in such quantities dangerous? And, in general, what harm does coffee cause to the body and is there any benefit from it?

The effect of coffee on human health is a favorite topic of debate between coffee lovers and its opponents. Since a healthy lifestyle is in fashion today, its adherents consider caffeine not very useful and try to drink coffee as rarely as possible and with a minimum caffeine content. However, doctors from England argue that caffeine is necessary for a person, because if you exclude from your diet all products that contain caffeine (coffee, tea, chocolate, etc.), the likelihood of headaches and irritability will increase. Therefore, to avoid this, a person needs to consume the amount of caffeine that is found in two cups of coffee, three cups of tea or half a bar of dark chocolate.

Scientists around the world are conducting research on the effects of coffee on health, the results of which do not yet provide a clear answer. Some studies show that drinking coffee leads to cancer, while others show that it eliminates cancer. diabetes mellitus. The effect of coffee on the human body is individual and depends on the characteristics of the body. For example, when considering the invigorating and stimulating effect of coffee, we can say that the influence of instant coffee has a stronger effect on health, but it is important to take into account the excitability of your nervous system. For many people, drinking a large amount of coffee does not have any stimulating effect.

However, no matter what effect coffee has on health, people's consumption of it is only increasing every year.

Composition of coffee.
Fresh coffee beans contain about two thousand substances, including water, caffeine 0.65-2.7%, fat 12%, proteins 13%. Roasting beans changes their composition, and the degree and duration of roasting determines the degree to which the composition of the coffee changes. In particular, the amount of caffeine increases to at least 1.3%, and when preparing instant coffee this figure increases to 5%. In addition, coffee beans contain calcium, potassium, iron, magnesium, 30 organic acids necessary for our body, as well as many other useful microelements and vitamins. One cup of coffee contains 20% daily norm vitamin P, which is necessary for our blood vessels.

Instant coffee and its harm.
Unfortunately, we do not drink coffee beans as often as we would like. We mainly use its soluble analogue in glass jars. However, instant coffee does not even remotely convey the taste and aroma of real coffee. Most of us are sure that instant coffee contains significantly less caffeine than real coffee. But everything is just the opposite; instant coffee, compared to beans, is the record holder for the caffeine content in its composition. Moreover, the more expensive and better quality instant coffee seems to us, the greater the amount of caffeine it contains. Therefore, doctors recommend drinking it as rarely as possible, and still giving preference to real coffee beans, prepared according to all the rules. Both taste and aroma, and are healthier!

Caffeine is a strong stimulant of gastric juice secretion, so people suffering from stomach diseases should remember this and not drink coffee on an empty stomach. In addition, instant coffee is a highly acidic drink, so it often causes heartburn if you drink it without adding milk.

When preparing natural coffee beans, the optimal water extraction of substances from the beans is 19%, and this is exactly what happens if all brewing rules are followed. Manufacturers of instant coffee think more about their benefits, so almost 50% of water-soluble substances from the beans are completely extracted into solution, that is, during the processing process, after 19% of the necessary substances are released, organic acids and other substances that are not responsible for taste and aroma begin to be extracted coffee, but only increase the acidity of this “drink”.

Harm from coffee.
Drinking coffee still cannot be called harmless. It is not recommended to drink coffee for people suffering from coronary heart disease and atherosclerosis (although there is evidence that coffee helps in the fight against atherosclerosis).
