Is it good to eat coffee? Impact on the children's body

People have loved coffee since ancient times. This drink has many fans, but there are also many who are sure that coffee is extremely harmful to the body. The truth, as usual, is out there somewhere. What exactly is the effect of coffee on the body? Let's figure it out!

Exist different kinds raw materials. The classic is made from roasted grains. The effect on the body is somewhat different, because this drink has a different composition. Another variety is green grains, about which there are many myths.

Composition of the product

The main ingredient is caffeine. It has a stimulating effect, the consequence of which is an increase in activity. Synthetic analogues of caffeine activate the vasomotor and respiratory centers of the brain, increase the activity of the cortex, and accelerate the transmission of nerve impulses.

The effect of coffee on the body is also due to other substances, an important place among them is occupied by alkaloids of caffeine and theophylline.

Roasted coffee beans also contain:

• tannins - give a bitter taste;
• caffeol (this component enhances blood circulation, lowers cholesterol);
• necessary for the walls of blood vessels;
• chlorogenic acid (important for protein metabolism);
• essential oils that provide unique aroma and taste.

Scientists have found more than a thousand biologically active substances in coffee beans that affect metabolism. Among them are amino acids, alkaloids, organic acids. The effect of coffee consumption on the human body is determined by the totality of all ingredients.

Many have heard of theobromine in coffee. The effect on the body of this component is similar to the effect of caffeine: it stimulates the work of the heart, nervous and respiratory systems. This component is indispensable in a stressful situation: it helps to cope with nervous tension, numbs pain, makes it possible to concentrate and find the right solution. But if you want to improve your health with theobromine, look for it in cocoa or chocolate: most types of coffee are actually practically free of this substance.

Effect on the heart and blood vessels

Drinking a drink briefly raises blood pressure. The pulse quickens immediately. But there is a nuance.

In coffee lovers who regularly drink their favorite drink, this effect is not observed. But for those who drink it very rarely, even a caffeine-free drink raises blood pressure. Doctors also noticed that coffee increases low blood pressure, but normal blood pressure does not. Clinical studies have confirmed that people who drink about 5 cups a day have little or no problems with elevated or reduced pressure. But it is worth increasing the amount to 6 cups, as persistent hypertension is guaranteed.

People with coronary heart disease should not drink coffee. This is due not only to the effect on the blood vessels, but also to the effect of coffee on the body as a whole. Studies have not established a link between the amount of coffee and susceptibility to heart disease. But modern medicine is quite clear: exceeding the recommended amounts leads to arrhythmias.

The effect of caffeine on blood vessels is rather positive. Drinking a drink in reasonable doses improves blood microcirculation in tissues, strengthens the walls. Many European medical centers for the treatment of heart disease recommend drinking several cups daily in addition to a low cholesterol diet for atherosclerosis.

It should be understood that moderate coffee consumption in no way harms the heart. In any case, there is no clinical and laboratory evidence of its harm. Drink a couple of cups a day and do not worry about the health of the cardiovascular system.

Effect on the nervous system

Caffeine also stimulates nervous activity: efficiency increases, fatigue decreases, a feeling of cheerfulness comes, the thought process is activated.

With daily consumption of 4 cups, the risk of developing Parkinson's disease is significantly reduced.

We must not forget about the negative impact of coffee on the body, in particular on the nervous system. Excessive stimulation of it is fraught with exhaustion. This pattern was studied by IP Pavlov at the beginning of the 20th century. Exceeding the recommended doses of coffee can have the following consequences:

• lethargy;
• drowsiness;
• prostration;
• lethargy;
• depressive states.

Influence on the genitourinary system

This drink has a pronounced diuretic effect. It is necessary to monitor the amount of fluid consumed. Regularly replace the loss of fluid, especially in the heat. The diuretic property can be used: it is recommended to drink the drink during colds and ailments.

It should be remembered that with increased urination, the body actively loses calcium.

Impact on the digestive system

Drinking on an empty stomach is not recommended. Caution should be taken with the drink for patients with gastritis and pancreatitis. Remember: coffee drink irritates the gastric mucosa, increases the production of gastric juice.

There is also a positive effect on the gastrointestinal tract - peristalsis is activated.

Impact on the liver

Currently, scientists do not have data on the negative effects of coffee on this organ. But for bile coffee is useful. Just a few cups a day help clear the ducts, which is an excellent prevention of gallstone disease.

coffee and metabolism

Biologically active substances, which are rich in brewed coffee beans, are involved in metabolism. The drink improves antioxidant protection, indirectly affects the reduction of the risk of diabetes.

It is generally accepted that coffee is addictive, but scientists assure that we can only talk about psychological addiction. Stop drinking coffee - and you may feel longing for the pleasant moments that he gave you in the morning or during a break. But you won't feel any breakage.

Under a big question and carcinogenicity. Coffee belongs to the third group (substances about which there is not enough data to refute or confirm the effect on the development of tumors). By the way, talc and mobile phones belong to the same category. A number of scientists believe that coffee does not increase, but reduces the risk of developing tumors. This issue is currently being actively investigated.

It is worth mentioning the effect on cholesterol. The drink indirectly affects the exchange fatty acids lowers cholesterol levels.

instant drink

A soluble drink has a stronger effect on pressure, the secretion of gastric juice. This pleasure is not just not recommended, but is categorically contraindicated for people with gastrointestinal diseases, pregnant women, and adolescents.

We must not forget that many manufacturers use the cheapest raw materials for the production of instant coffee. The quality of natural grain is much higher.

green coffee

You can cook delicious healthy drink and from unroasted grains. Such a product is popular with those who want to lose weight. excess weight. Its taste and smell are not as expressive and pleasant as those of the usual classics brewed in a Turk. But there are more useful substances in grains that have not been roasted.

The components of green coffee really accelerate the metabolism, which contributes to weight loss. In addition, the drink helps to restore strength for a new workout. But do not hope that the result will come by itself: green coffee only promotes weight loss, and does not magically cause it. Kilograms will go away, but for this you need to try, combining proper nutrition with reasonable exercise.

The effect of coffee on the female body

It is believed that regular use natural drink reduces the risk of getting pregnant. You can not consider this drink as a contraceptive, but for ladies trying to conceive a child, it is better to keep consumption to a minimum.

During menopause, the harm of coffee is associated with calcium leaching. During lactation, the drink is all the more undesirable for the same reason.

If there is a benefit of this drink specifically for the woman's body, then it is currently unknown about it. However, scientists have long confirmed the contribution to weight loss of natural varieties of coffee.

The effect of coffee on the human body

But for men, this drink is useful. Coffee can be attributed to natural aphrodisiacs: it prolongs and enhances potency, stimulates the sex glands. However, this statement is true only for healthy men. Studies have not revealed any positive or negative effect of coffee on impotence.

But you shouldn't get carried away with this drink. Excessive consumption can lead to increased levels of estrogen (female sex hormones). In this regard, instant coffee is also more dangerous than natural coffee.

It is believed that coffee can provoke the progression of prostatitis.

How to and how not to

In reasonable quantities, the drink is harmless. The number of cups depends on many factors. The effect of coffee on the body is also determined by the individual reaction. The average dose should not exceed 3-4 cups per day. For a morning cup, be sure to grab a couple of sandwiches, sweets, gingerbread. At lunchtime, enjoy a drink after your meal.

To increase the benefits of coffee, combine it with other products: milk, cream, ice cream, honey, cinnamon, lemon.

• neurotic phenomena;
• vomiting;
• tachycardia;

Coffee is a drink whose benefits and harms have been debated for many years. Some accuse him of all "sins" and consider him the most harmful drink. Others, on the other hand, are fiercely protective. What are the real and scientifically based pros and cons of this drink, we will consider in this article.

Depending on who you ask about the beneficial properties of coffee and its effect on the human body, the answers will be different. The health effects of coffee are indeed controversial. Therefore, some will answer that it is super healthy drink, while others will call it the most harmful and useless drink in the world. Both will be right. In fact, coffee has many beneficial properties and can provide certain benefits. For example, it contains many antioxidant compounds and may reduce the risk of many diseases.

But there is harm in this drink and some people are strictly forbidden to drink it. We must not forget that it contains caffeine, which can cause insomnia.

Where coffee grows

Coffee is a drink made by brewing coffee beans.

Like many popular drinks such as tea and cocoa, coffee, or rather the coffee tree, grows in warm countries. This tree belongs to the genus of the same name - coffee of the madder family.

Ethiopia is considered the birthplace of the coffee tree, from where it was brought to the Arabian Peninsula in the 14th century, and only in the 16th century did it first appear in the Ottoman Empire, and then spread to Europe.

Coffee spread around the world began in the 17th century, first in the West Indies, where coffee tree grains were secretly brought, and from the end of the 17th century, thanks to Dutch navigators, it came to the islands of Java and Sumatra. This expansion ended the Arab monopoly on the ownership of coffee plantations.

This Short story distribution of the coffee tree around the world. Europeans receiving seedlings coffee trees, exported them to their colonies located in tropical latitudes. At the same time, the birth of a world-wide famous varieties coffee.

Today coffee grows in many countries South America, Africa, in the countries of the Asian and Indian continent.

Varieties of coffee

The main varieties of coffee are:

Robusta or Congo coffee.

These two coffees account for nearly 98 percent of the coffee market, of which 70 percent is Arabica and the remaining 30 percent is Robusta.

In addition to these main varieties of coffee, there are others, but less significant in industrial scale, such as excelsa, liberica, luwak.

Collected coffee beans Before they get to us, they go through a certain path of preparation.

The collection of coffee is mainly carried out by hand. In Brazil, for example, semi-mechanical methods of collection are used, when first special device shake off the grains and then rake them into heaps.

After sifting or sorting by hand, the collected grains undergo a fermentation process. Before fermentation, coffee beans are loaded into special rubbing machines, where the collected beans are removed most of pulp, and then they are placed in tanks, where, under the influence of their own enzymes, the remaining part of the fruit shell decomposes.

After fermentation, the grains are washed with water, as a result of which the remaining pulp is removed. And only after that the coffee beans are dried in the sun or in special drying cabinets.

In the sun, coffee beans can dry from 15 to 20 days, and they need to be turned over every 20 minutes so that they do not start to rot. In drying cabinets, this process is faster.

The most important thing during drying is to prevent overdrying of coffee beans when they are already losing their marketable condition and nutritional value.

After all this technological chain of preparation, the grains are packed in bags and sent to the consumer, where they are already being further processed.

Composition of coffee

Coffee beans contain some essential nutrients. First, they are a rich source of antioxidants.

In addition, coffee contains:

Vitamin B2 (riboflavin);

Vitamin B5 (pantothenic acid);

Vitamin B1 (thiamine);

Vitamin B3 (niacin);

Vitamin B9 (folic acid);

Minerals: manganese, potassium, magnesium, phosphorus.

Although this amount of nutrients is only a few percent in terms of 1 cup of 240 grams (from 1 to 3 percent, with the exception of vitamin B2 - 11 percent and vitamin B5 - 6 percent), their content in quantitative terms may not seem so significant. But if you consider that many of us drink more than one cup of the drink during the day, then you get a decent dose.

Yes, and antioxidants play a certain role. useful role, which many people get from coffee, and not from vegetables or fruits.

As for the calorie content of coffee, it is a low-calorie drink. Of course, its calorie content fully depends on the other ingredients present in the drink. calorie content natural coffee, prepared from ground grains without the addition of sugar, milk and other components, is only 1-2 calories per 100 grams.

The main controversy is what is contained in coffee. Caffeine is the world's most widely consumed psychotropic substance. its effect on the human body and the impact on health have been studied quite well. But coffee does not consist of caffeine alone, but has a more complex composition consisting of various substances. and there is no complete certainty that it is caffeine that is the main “enemy” of human health.

Harm coffee

However, it has no less harmful properties, however, as it should be noted, many of them are tied to excessive consumption and the quality of coffee itself. It is also worth considering that scientists are still arguing over some of the qualities of this drink, without coming to a final opinion. Here is a list of potential harm to the human body.

Coffee Bad quality may be toxic. Poor quality coffee can contain many impurities that can cause headache, poor health and even lead to diseases. This can happen if the coffee is made from beans whose integrity has been damaged for some reason or they are affected by rot and more. Even one such bean can ruin coffee.

Excessive coffee consumption can lead to death. True, for this you need to drink 80-100 cups, which is about 23 liters. The lethal amount of caffeine for humans is 13 grams. True, until an overdose of caffeine occurs, even earlier you will be tormented by vomiting and nausea.

Coffee can cause insomnia. With excessive use, it causes overexcitation of the nervous system, which can come back to haunt you with a headache, a feeling of overwork, inexplicable anxiety, etc. Also, in this case, it can lead to insomnia. That's why maximum amount caffeine during the day should not exceed 400 milligrams, which is equal to 4 cups (240 ml each) of the drink.

During pregnancy, you should not drink more than one cup of coffee. Although research data on the effect of coffee on the fetus is contradictory, it is better to limit the use of the drink during such a period or completely eliminate it.

As a result of the above, people suffering from problems with the cardiovascular system should also be treated with caution. The unequivocal harm of coffee for them has not been proven, but there is no data on its complete safety.

Coffee actively affects digestion, promoting the secretion of gastric juice, so it is not recommended to drink it for people with an ulcer or gastritis. It is especially harmful if you drink it on an empty stomach.

There is an opinion that coffee is addictive, and then addictive, but to date, scientists' data on this matter are extremely contradictory.

As you can see, coffee has both benefits and can be harmful to the body. Moreover, the benefits and harms are almost equal. Everything depends on the state of health.

If there are no contraindications to drinking this drink, then coffee can prevent a number of serious diseases. And of course, it all depends on the amount of coffee you drink. Studies have shown that it is useful to drink from 1 to 6 cups. And the most the best option- 4 cups a day.

Let's first understand all the advantages and disadvantages of coffee. Let's just clarify that we use proven scientific data and the results of the latest research. But the opinions of scientists are quite contradictory. Some believe that the benefits of coffee are a strong argument for drinking it in moderation (3-4 cups a day). Others believe that the harm from coffee covers all of it. beneficial features. It was previously believed that coffee can negatively affect the body due to the high dose of caffeine it contains. It was even believed that it can provoke the development of cancer of the intestines and other parts of the gastrointestinal tract. Now these arguments have moved into the section of myths. Recent studies on 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 can speed up the metabolism. Thanks to this ability, under the influence of coffee, the intestinal mucosa and other organs are updated.

Until now, most of the components that make up coffee have not been studied.

Health benefits of coffee

The health benefits of coffee are undeniable:

1. Since these fragrant grains contain caffeine, coffee can have a stimulating effect on the psyche and nervous system. Caffeine is a powerful alkaloid. It is he in more affects both the benefits of this drink, and its harm. The beneficial properties of caffeine are that it is an excellent stimulant of cardiac activity and the nervous system. It is its action due to the fact that after a cup of coffee we feel a surge of energy. This is a great and proven way to increase productivity. A cup of high-quality, properly brewed coffee can energize you for the whole day and good mood. Caffeine raises blood pressure, so you need to make sure that it enters your body in moderate doses. For hypotensive patients, a cup of coffee can be a real salvation from low pressure. But for hypertensive patients, drinking this drink is extremely undesirable, as it can provoke even higher pressure.
2. Caffeine improves brain activity, namely, improves memory and attention.
3. Increases performance.
4. Fragrant grains help to avoid type 2 diabetes. What does this have to do with amazing property? The fact is that coffee contains a unique combination of caffeic, chlorogenic acid and caffeine. All these substances interfere with the accumulation of amyloid protein. But it is the amyloid protein that leads to the appearance of the second type of diabetes mellitus.
5. It is the prevention of the development of incurable Parkinson's disease. Surprisingly, scientists have found a link between moderate coffee consumption and the prevention of Parkinson's disease. Those members of the experimental group who regularly drank several cups of coffee a day, practically did not suffer from this terrible disease. It was found that coffee can have a beneficial effect on the state of the brain and central nervous system. But a caffeine-free drink does not have such an effect. In fact, decaffeinated coffee loses most of its benefits. magic drink.
6. It is the prevention of cardiovascular diseases, stroke. This effect is explained by the fact that coffee is able to expand the lumen of the vessels of the heart and brain.
7. Improves secretion in the stomach. Caffeine and other components of coffee effectively stimulate the process of juice secretion in the stomach, increasing acidity. This property can be used by those patients who have been diagnosed with gastritis with low acidity. Coffee will help increase it and improve the process of digesting food.
8. Helps fight depression. The antidepressant properties of coffee are especially good in women. Of course, a drink alone will not cure clinical depression, but this popular drink can be used for prevention and to combat mild depression and blues.
9. May prevent the development of cirrhosis of the liver. These data were provided by American scientists. They found that coffee can prevent the development of cirrhosis in patients who abuse alcohol. But most likely, this effect is no longer associated with caffeine. Something else comes into play here. active substance. So far, there is no exact information about him.

What is harmful coffee

Is coffee bad for health? We have listed the main beneficial properties of coffee, which have long been proven from a scientific point of view. But we should also not forget that coffee can harm our body. Most often harmful overuse coffee. 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, primarily caffeine. So, what can harm coffee.

1. Sometimes it can provoke tachycardia and insomnia. This effect is observed in people prone to increased excitability. In them, by nature, the processes of excitation in the central nervous system predominate over the processes of inhibition. Coffee is not able to cause such an effect. He can only make it worse.
2. Coffee is contraindicated in hypertensive patients, especially in large doses. The immoderate use of a fragrant drink for a person prone to high blood pressure is fraught with a deterioration in his general condition. In the worst case, even a hypertensive crisis can begin. Therefore, people who are prone to high blood pressure can occasionally drink only a cup of strong coffee. At the same time, you need to listen to how your body reacts to the drink.
3. May raise cholesterol levels. This effect is associated with the action in the composition of coffee of a substance such as cafestol.

A low content of cafestol in instant coffee has also been found. It is important to remember that cholesterol can be the culprit in the development of cardiovascular diseases. A direct link has been established between high cholesterol levels and the development of such dangerous pathologies as myocardial infarction, angina pectoris, and atherosclerosis.
4. May be somewhat addictive. Do not classify coffee as a drug. Oddly enough, but there is such an opinion. It is related to the substance caffeine. It, as we have already mentioned, is an alkaloid. Therefore, there was an opinion that coffee is addictive and even addictive. This is not entirely true. People who drink a lot of coffee and do it regularly can really feel overwhelmed and lifeless without it. Without their favorite cup of coffee, they become drowsy, lose their mood, and even get a headache. But this, of course, is not the addiction that is observed in drug addicts. Therefore, experts advise not to abruptly give up coffee. If you decide to take a break and replace your usual coffee with another drink, give it up gradually. Lower your caffeine dose every day. Make your coffee less strong, drink less. This way you will avoid the so-called withdrawal syndrome.
5. May increase the acidity of gastric juice. It is well established that the components contained in coffee are able to increase the secretion of gastric juice and increase its acidity. If for people with low acidity, this is a useful property, then for those who have high acidity, this drink is contraindicated. If there is no aggravation, then sometimes you can afford a cup of this magical drink, but not on an empty stomach. If you drink it after eating moderate amounts, there will be no harm. But those who have been diagnosed with a stomach ulcer should not drink coffee.
6. High calorie counts. By itself, coffee has virtually no calories. A cup of black instant coffee without sugar contains only two calories. But it is worth adding sugar, milk, cream or honey, and the calorie content of the drink will increase hundreds of times. If you are obese or just have extra pounds, then it is better to drink coffee without such high-calorie supplements. It may not be as tasty, but you will be provided with only the beneficial properties of the drink. In extreme cases, you can add a little sugar.
7. Negatively affects pregnant women. Doctors have long noted that the components of coffee negatively affect the condition of the pregnant woman and the fetus. This is primarily due to the fact that caffeine is able to stimulate blood circulation and increase vascular tone. For pregnant women, this is very undesirable, since caffeine can provoke an increase in pressure. It negatively affects the placenta and can even increase the tone of the uterus. Of course, this effect will not be after one cup of weak coffee. With a strong desire, you can still afford to drink a cup of weak coffee at least occasionally. In this case, you should listen to how the body reacts to it. You also need to remember that caffeine is able to pass the placental barrier. This means that the baby's tiny body will be exposed to its powerful stimulating effect. The result is the following - during pregnancy it is better to refuse any kind and type of coffee.
8. Powerful diuretic action. Coffee is able to remove fluid from the body. On the one hand, this positive effect- so you can get rid of extra pounds. On the other hand, the rapid elimination of fluid can lead to dangerous dehydration. Therefore, coffee lovers need to drink plenty of fluids. This will keep the body from dehydration.
9. Affects the central nervous system, thereby stimulating it. This can provoke increased excitability, insomnia, panic attacks. But to get this effect, you need to drink a lot of coffee.
10. Able to flush calcium from the body. This damages the bones and teeth. Other trace elements may also leach out. This negative impact It is also very dangerous for a pregnant woman and an unborn child.
11. Causes darkening of tooth enamel. It has long been established that tea and coffee stain the enamel of the teeth in an unsightly yellowish tint. This is due to the fact that these drinks contain a large amount of coloring substances. This is also why coffee stains are so hard to get out of clothes. Especially fast tooth enamel turns yellow from strong coffee. Also, do not drink coffee with ice cream. In this case, the teeth will suffer from a strong temperature difference. That's why you shouldn't combine hot coffee and cold ice cream.
12. Reducing the size of the breast. This is the most unexpected negative effect of coffee. Scientists recently found that frequent drinking of strong coffee can reduce breast size in women. This can be a strong argument for women to reduce their daily dose of caffeine.

Some interesting facts about instant coffee

Here are some important facts that you will need to know about this popular drink.

1. Instant coffee is of significantly lower quality. We are used to instant coffee. It was invented not too long ago.

Although it is much more convenient to simply pour boiling water over instant coffee than to brew insoluble coffee, it is better to prefer the latter.
2. Remember that manufacturers often add dyes, antioxidants, stabilizers, flavors to instant coffee. If there are no such additives in coffee, it is called organic.
3. Instant coffee has the same positive and negative qualities that of the grain variant. But they are not so pronounced.
4. The technological process of growing coffee is almost always associated with the use of pesticides. After the coffee is extracted, they can easily end up in the finished instant coffee. In this case, they will definitely be in a cup with ready drink. Therefore, try to buy coffee from large trusted manufacturers. They value their reputation and try to use high quality raw materials.

green coffee

Despite the fact that this coffee is not roasted, it is still affected by high temperatures. And if we are talking on the production of powder or granulated coffee, then it is also subjected to high pressure. A lot of useful components are preserved in freeze-dried coffee. At the same time, a decoction of grains is made, then it is frozen and dried in a vacuum.

Is it true that green coffee contains significantly less caffeine? This green coffee is supposedly very different from roasted coffee. Actually, this is a myth. Caffeine belongs to the group of alkaloids. Heat treatment practically does not affect its condition and concentration. Roasted coffee will have as much caffeine as green coffee.

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 green coffee drinks are made. Most often, manufacturers simply add fruit flavors and call their product a fruit drink.
