Scientists have found that every cup of coffee consumed per week reduces the risk of heart attack by seven percent and stroke by eight percent compared to those who do not drink this drink.

Experts came to this conclusion using machine learning based on data from the long-term Framingham study. It has been held in the American city of Framingham since 1948 and includes information about people's diets and their condition. of cardio-vascular system.

Scientists compared data obtained using machine learning with data from traditional analyzes and found a link between coffee consumption and a lower risk of heart attack and stroke.

Coffee with sugar called a healthy “cocktail” for the brain

The combination of caffeine and glucose is an ideal nutritional “cocktail” for the brain, say Spanish neuropsychologists. 40 healthy volunteers took part in the experiment by specialists from the University of Barcelona.

All of them underwent magnetic resonance imaging (MRI) of the brain to determine the foci of excitation and the strength of the impulses. Half of the subjects were offered to drink sweet coffee before the study.

And it turned out that it was these people who experienced increased activity in the areas responsible for the formation of working memory and attention.

The benefits of coffee for prolonging life have been proven

American scientists have shown

Daily use coffee reduces the risk of mortality from all causes. To do this, experts observed about 190 thousand volunteers for 16 years. of various origins. The corresponding study was published in the journal Annals Internal Medicine, and was briefly reported by the University of Southern California (USA).

Experts observed about 190 thousand volunteers of blacks, Japanese Americans, whites and Hispanics. The survey participants, whose age at the start of the study ranged from 45 to 75 years, depending on their coffee consumption, were divided into several groups.

The average follow-up period was 16 years; by the end of the study, about 60 thousand people had died, of which 36 percent cardiovascular diseases and 31 percent from cancer.

After adjusting the study results (for gender, age, smoking, alcohol consumption and level of physical activity), it turned out that drinking one cup of coffee a day reduced the risk of mortality from all causes by an average of 12 percent, and three by 18 percent.

This result did not depend on whether the drink contained caffeine. Coffee contains many antioxidants and phenolic compounds that play an important role in cancer prevention, study co-author Veronica Setyawan explained.

Coffee has long become one of the most favorite drinks all over the world. 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 the beneficial and harmful properties of the 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. You can find a variety of substances in coffee beans, 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 activity 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% of the daily value of 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.

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.

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.

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, content useful substances 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 a 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.

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 and a large number of Drinking 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 extent 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 much 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, as it seems to us, instant coffee, the large quantity it contains caffeine. 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). You should also avoid drinking coffee if you have kidney disease, insomnia, increased excitability, hypertension and glaucoma. As you know, coffee should not be consumed before bed; you can drink the last cup a few hours before bedtime. In addition, coffee is not recommended for children and older people.

It should be noted that by consuming a certain dose of coffee, mental and physical performance increases, reaction improves, physical activity increases, brain excitability increases, and the respiratory center is stimulated. Again, the optimal dose of coffee reduces fatigue and drowsiness, and to a small extent neutralizes the effect of sleeping pills and narcotic substances. But the harm of coffee lies in the fact that it is very difficult to determine this very dose on your own, and the effect of caffeine on each person is individual, and depends on the type of nervous system. Even a slight excess of the dose leads to depletion of nerve cells, as well as disruption of the functioning of the body. It is for this reason that coffee should not be given to children; it disrupts the growth and development of the child’s body.

Scientists have proven the effect of coffee on cardiac activity, which is expressed in its strengthening, stimulation of the vasomotor center, and increased heart rate. Drinking coffee also slightly increases blood pressure, so people with arterial hypertension and various diseases cardiovascular system, as well as people with a predisposition to these diseases.

Scientists have proven the harmful effects of coffee on the body of a pregnant woman. Drinking four or more cups of coffee daily by a pregnant woman increases the risk of miscarriage (33%). However, if future mom drinks less than four cups of coffee a day, the risk of miscarriage quickly decreases, and the risk of fetal death in the womb also decreases to 3%. Coffee is most harmful after 20 weeks, so pregnant women are advised to avoid drinking coffee during this period.

Coffee inhibits absorption and promotes the leaching of microelements such as magnesium, calcium, sodium, potassium, etc. Therefore, coffee lovers are recommended to take vitamin complexes and also include in their diet more foods that are rich in these microelements. This is especially true for the fair half of humanity. Drinking more than four cups of coffee daily by a woman increases the risk of osteoporosis (brittle bones). Therefore, for lovers of this aromatic drink you should consume more calcium, as in vitamin complexes, and in the form of products.

Many of us think that by drinking decaffeinated coffee, we are saving ourselves from its harmful effects. Yes, that's right. But then another danger appears. Processing process coffee beans and getting rid of caffeine is accompanied by the use of chemical substances. Then the question arises: what is more harmful?

It has been scientifically proven that exceeding the individual dose by a person leads to the formation of dependence, which manifests itself in the form of severe fatigue, drowsiness and depression. At the same time, the effect of caffeine gradually weakens, which leads to the need to constantly increase the dose to achieve the same effect.

The benefits of coffee.
In addition to the harmful effects, the benefits of coffee are certainly obvious. Coffee is effective means improving mental activity for people engaged in logical activities, improves mental and physical performance. Drinking coffee has a positive effect on a person’s mental health, resulting in increased resistance to stress and depression.

In addition, the health benefits of coffee are great. Drinking two cups of coffee daily helps reduce the risk of pancreatic, liver, rectal and colon cancer, and in smokers, the risk of blood cancer. Drinking coffee reduces the risk of Parkinson's disease, with women recommended to drink coffee in moderation and men in large quantities. Coffee is a means of preventing diseases such as migraine, liver cirrhosis, hypertension, cholelithiasis, asthma, atherosclerosis, and heart attack. Drinking at least six cups of coffee daily can reduce the risk of diabetes in men by half and in women by a third.

Coffee is an effective means of improving reproductive function in men and increases sperm motility.

Coffee has been proven to help with weight loss. Drinking one cup of coffee increases the intensity of your gym sessions by a third. When dieting and exercising, coffee helps the body begin to use only fats for energy. In addition, coffee is a source of antioxidants that help maintain youth and beauty. Coffee also helps digest food, so after lunch you can drink a cup of this delicious drink.

Beneficial features coffee is also used in medicine. Caffeine is used for drug and poison poisoning, vascular spasms, various infectious diseases, and cardiovascular failure. Caffeine is the main component of many drugs: Caffetamine, Askafen, Novomigrofen, Pyramein, Novocephalgin, Citramon.

In conclusion, I want to say that everything should be in moderation. You shouldn't make coffee the meaning of your life. The drink should bring pleasure and enjoyment of the aroma, and not lead to the appearance of various “sores” due to its excessive consumption.

If you like to drink a cup of coffee with a piece of cake or other dessert, then you have probably wondered at least once whether coffee is harmful or beneficial.

The main component providing positive impact on some mechanisms in the human body - this is caffeine. It can be beneficial in some quantities, but if consumed in excess, it can cause harm to the human body. That is, coffee can be both beneficial and harmful to humans. Let's take a closer look at the harmful properties of coffee.

Harm from coffee

1. At frequent use Coffee has a harmful effect on the nervous system. Caffeine stimulates the cardiovascular and nervous system, and with frequent use, the body is constantly in an excited state, which is why it quickly becomes exhausted. The normal functioning of all body mechanisms is disrupted, which leads to stress. Excessive coffee consumption can cause attacks of aggression and psychosis, so you should not drink it too often.

2. Black coffee is harmful to the cardiovascular system. The stimulation of the cardiovascular system due to the action of caffeine is short-term. After drinking coffee, a person's blood pressure rises and their pulse quickens. This effect can be dangerous for hypertensive patients, people with coronary heart disease and tachycardia. Coffee disrupts the natural rhythm of the heart and can worsen the health of not only a sick person, but also a healthy person if consumed excessively. To prevent coffee from harming the heart and blood vessels, people with cardiovascular diseases are not recommended to drink coffee at all; healthy people are advised to drink coffee in moderation, no more than 2-3 cups a day.

3. Coffee flushes a number of things out of the body useful elements, including vitamins B1 and B6, potassium, calcium and magnesium - this is another harmful property coffee. A lack of these elements in the human body can lead to health problems.

It is especially harmful to drink a lot of coffee during adolescence, when the musculoskeletal system is just developing, and the lack of calcium can lead to its improper formation. A lack of vitamins B1 and B6 can lead to impaired cerebral circulation, which can cause headaches and a number of other diseases associated with mental activity, attention, and reaction speed.

It is harmful to drink coffee during pregnancy, since the fetus may not receive enough of the above microelements, which coffee washes out of the woman’s body, which can lead to disturbances in the development of the child.

4. If consumed frequently, coffee becomes addictive. People addicted to coffee may experience symptoms such as fatigue, depression, drowsiness, and drowsiness. To cheer up, a person drinks coffee, but over time its effectiveness decreases and the coffee lover needs more caffeine. So a person drinks more and more coffee, which has an increasingly detrimental effect on his body.

5. Another harm from natural coffee is that if consumed frequently, it leads to mental disorders such as paranoia, epilepsy, and psychosis. Coffee stimulates the active functioning of the cardiovascular system, and if a person is in this state often, then stress appears. Due to being under constant stress, a person becomes aggressive.

6. The harm of coffee for women is that when excessive consumption Drinking coffee during pregnancy increases the likelihood of miscarriage. Therefore, women are strongly advised not to drink coffee during pregnancy.

Coffee can be both beneficial and harmful to humans. It all depends on the characteristics of the body and the amount of coffee consumed. To a healthy person You can drink 2 - 3 cups of coffee a day and there will be no harm from it. But if a person has hypertension and vascular disease, then it is not advisable for him to drink coffee. It is useful for asthmatics to drink coffee; consuming 2 - 3 cups will help improve breathing and slightly reduce the severity of the attack.

Black coffee is a drink that has an active effect on the human body, so you can drink it in small quantities, only in this case its consumption will be beneficial for the person. Frequent and excessive consumption can be harmful to a person, so if you drink a lot of coffee, we strongly recommend that you reduce your dose to maintain your health.

Almost everyone cannot imagine their morning without a cup of aromatic black coffee. Until now, scientists are conducting many studies to prove whether this drink is beneficial or harmful.

The latest innovation is coffee with the aroma of rum, citrus, and cinnamon. How healthy is this drink? Does caffeine cause addiction? Could coffee be a major cause of serious illness?

How did we learn about coffee?

For the first time about unusual drink they started talking in Caffa. Ethiopian shepherds began to notice that their goats, after eating fruits from an unknown red tree, suddenly became active. Then people began to prepare a tasty and aromatic drink from the grains.

But coffee came to Russia only in 1665, when the country intensified trade relations with the Middle and Near East; coffee had long been popular there. In Russia, the drink was practically not widespread due to religious prejudices. Only thanks to Peter I, who loved to drink coffee in Holland, this drink became popular in Russia. Already in 1812, the first coffee shops began to open.
