What happens to a person who drinks coffee? What happens to the body if you drink coffee every day or refuse it? Why do people drink coffee.

Caffeine is the most popular psychoactive drug in the world. And this, it is worth noting, is well deserved. Especially if we talk about it in the context of a cup of coffee, without which the morning would definitely be incomplete (and also not so cheerful and pleasant). But even desperate coffee lovers sometimes worry about whether they drink too much coffee. And all because we constantly hear about in order to obtain certain health bonuses.

Fortunately, this coin also has a downside. All the same scientists regularly conduct studies involving coffee, aimed at evaluating its usefulness. No, they do not deny that exceeding the norm of consumption (up to 400 mg of caffeine per day) can provoke sleep problems, cause unreasonable and cause heart palpitations. But they still recommend drinking coffee in moderation - and here's why.

Liver condition

A review combining the results of nine studies and published in the journal Alimentary Pharmacology and Therapeutics found that drinking more coffee is associated with a lower risk of cirrhosis. Scientists have found that just one cup of coffee a day reduces the risk of liver disease by 22%, two cups - by 43%, three cups - by 57%, and four cups at once by 65%.

Diseases of the heart and blood vessels

According to the BMJ, a review of more than 200 studies on the topic found that people who drink 3-4 cups a day are 19% less likely to die from cardiovascular disease. Especially, scientists note, it works in people at risk of heart failure.

type 2 diabetes

Oncological diseases

A review published by the European Journal of Cancer Prevention reported that coffee drinkers who drink at least three cups of strong black coffee a day have an 18% lower overall risk of cancer than those who do not. In another scientific review reported by Business Insider, at least one cup of coffee a day was found to reduce the risk of liver cancer by 15%. Some case study evidence also suggests that coffee drinkers may be less likely to develop cancer of the mouth, pharynx, or prostate.

Alzheimer's disease and dementia

A meta-analysis of studies on coffee consumption and brain health found that coffee drinkers in all its forms are 16% less likely to develop Alzheimer's disease, or cognitive decline in general (according to the Journal of Alzheimer's Disease). There are also smaller studies that suggest that coffee consumption leads to a progressive reduction in the risk of Alzheimer's disease.

Depression

A large study of more than 50,000 women and published in JAMA Internal Medicine found that at least one cup of sugar-free coffee per week reduced the risk of developing by about 15%, and 2-3 cups per day - by 20%. Another study of over 100,000 men and women found that regular coffee drinkers of both sexes were 45% less likely to attempt suicide.

Total mortality

One large study (participants - more than 500,000 Europeans) says that men who drink three or more cups of coffee a day have a 12% lower risk of dying. At the same time, according to BI, in women, the risk is reduced by only 7%. Scientists add that coffee drinkers are less likely to die from circulatory problems and digestive system diseases. So how about a cup of strong and fragrant?

The peculiarity of this popular drink is that it affects almost all the main organs of the body, from blood circulation to the organs of vision, and it acts almost instantly - just a few minutes after drinking, writes MyJane.ru.

Here is what happens to a person about an hour after drinking a cup of coffee (some of the facts are quite surprising):

Brain
Coffee is needed not only to stay awake over a boring task. The caffeine contained in this drink is indeed a powerful stimulant. But it not only prevents you from falling asleep, but also enhances mental abilities for a while and helps you better concentrate on the task at hand. Caffeine is a psychoactive substance that improves chemical bonds in the brain. In moderate doses, it sharpens attention and allows you to concentrate mental abilities on the task at hand. Begins to act 30 minutes after consumption and lasts for several more hours. So if you have to brainstorm, you need to be behind the wheel for a long time or you need to shake things up quickly, then a cup of coffee is exactly what you need. But "moderation" in this case is the key word: an excess of caffeine overloads the nervous system and leads to nervous stress.

Eyes
Caffeine also speeds up the sympathetic nervous system, which is responsible for the subconscious activity of the body. That is, it sharpens the instincts and turns on the “hide-or-fly!” mode, as if you were in danger. This mode stimulates brain receptors and promotes the production of adrenaline. It also sharpens your vision for a while (so you can better see hypothetical enemies and see where to run). So half an hour after a cup of coffee, you can see better. The pupils dilate slightly. True, this expansion is so weak that you are unlikely to notice it in the mirror.

Teeth
With frequent use of coffee, the coffee pigment can give the teeth a yellowish coating. But coffee in general is good for teeth because it contains a large amount of polyphenols that effectively fight tartar and bacteria. But only on the condition that you drink "clean" coffee, without the addition of sugar, milk or cream. Sweet coffee with milk is not only not useful, but also harmful, because as soon as polyphenols dissolve the top layer of plaque, sugar, regular or milk, gets easy access to the cleaned tooth enamel. This can lead to enamel demineralization and even to caries.

Heart
If you often drink coffee, then most likely you have learned from your own experience that the cardiovascular system reacts most quickly to coffee. Caffeine increases the sensitivity of the nerve channels, so that the electrical impulses that “accelerate” the cardiovascular system pass through them more easily. Accordingly, about 15 minutes after drinking coffee, the pulse quickens by 10-15% and blood pressure rises (the exact figure depends on how much coffee you drank, how familiar you are with this drink, how much you ate before and what medications you took) . In general, two cups of coffee a day carries no risk for most people. But exceeding this amount is not recommended for people with heart disease, high blood pressure and tachycardia.

Stomach
If you have an acidic stomach, drinking coffee can cause heartburn because it has the ability to relax the sphincter that prevents heartburn in the esophagus. With low acidity of the stomach, coffee is useful - it increases the secretion of gastric juice by 10-15% and helps to digest food faster.

Intestines
Along with speeding up the digestion of food in the stomach, caffeine also stimulates the intestines, making them work faster and harder. But food still needs a certain amount of time to be properly digested. If she moves through the intestines too quickly, then this is fraught with diarrhea. And in this case, people suffering from irritable bowel syndrome fall into the risk group.

Bladder
As most coffee drinkers probably know, it's best not to drink this drink unless there's a toilet nearby. Indeed, coffee is a strong diuretic, stimulating the kidneys and bladder to remove more fluid from the body. Interestingly, the diuretic properties of coffee do not depend on whether you drink regular or decaffeinated coffee. So in this case, the responsibility lies not with caffeine, but with other stimulating steroid-like components, of which coffee is abundant.

Fat deposits
If you don't snack on coffee cakes, then you probably didn't think about fat in relation to coffee. But in fact, coffee is a rather fatty product containing a lot of natural oils. True, they are usually delayed by the filter. But some unfiltered coffee brewing methods, such as coffee makers or French presses, leave oils in the drink and droplets can be seen on the surface. But since coffee speeds up metabolism, while allowing you to lose many more calories than coffee contains, these oils add little to no body fat.

And here are some more interesting facts about the effect of coffee on health:
Coffee beans contain antioxidants from the quinine group. Interestingly, they become more effective after roasting the beans.
Coffee drinkers reduce the risk of type 2 diabetes.

Coffee is actually not that dehydrating.


Caffeine was once thought to be a powerful diuretic, but this is actually not true. Unless it is consumed in large amounts (500 to 600 milligrams a day, or two cups of coffee), you won't have any negative effects. In fact, studies have shown that urine output does not change significantly when a person drinks a caffeinated beverage rather than something decaffeinated, such as water. Therefore, if you enjoy a cup of coffee in moderation, you should have no reason to worry.

As a result, coffee drinkers have a lower risk of developing diseases such as Parkinson's disease, type 2 diabetes, and heart disease. But here's the thing: Coffee drinkers are also more likely to have bad habits like smoking cigarettes, drinking a lot of alcohol, and eating red meat, so the study was adjusted to show what might happen if these other factors weren't present.

Almost every modern person has tried coffee at least once, many cannot even imagine their life without this invigorating and tart drink. The question of the effect of coffee on our body is of interest to many, as well as why people are so attached to it, and do not agree to live without it even one day. Although the answers are obvious, there are many opinions on this subject, and it is worth exploring these issues in more detail.

There are many ridiculous legends about the distant past of coffee, including even torture with the use of a drink. Allegedly caught opponents were given strong coffee by force so that they would later become more talkative and give out important data. Of course, these are all fairy tales invented by people for entertainment.

Who Invented Coffee?

At the moment, it is quite difficult to get to the bottom of the correct information, even several centuries into the past. History is constantly being changed, facts are distorted or removed from books altogether, some artifacts important for history have been deliberately destroyed. Yes, and research methods have their own errors, which is why it is impossible to find out what actions and processes led to the current popularity of coffee around the world. The only thing that's for sure is that people invented drinking coffee, because we are the only intelligent creatures on the planet.

Alternatively, the demand for coffee stretches back to ancient times, when people were so delighted with the effect that the drink has that the popularity has remained to this day. The earliest data on coffee are found in the period of the ninth century BC, when such familiar objects as coffee grinders, coffee machines, coffee houses could not even be dreamed of. Now we are already so involved that everything seems to be taken for granted, and the majority of the population does not even think about the customs and life of people in the old days.

In any case, it is very fortunate that the custom of drinking coffee has reached the present, and let scientists continue to make new and exciting discoveries about our planet and life in ancient times.

How does coffee affect the human body?

Many undertake to prove the usefulness of drinking coffee, but you need to know that it causes an increase in blood pressure, the heart beats more often, blood vessels dilate, some cannot fall asleep quickly after a cup of drink. For these reasons, you should be careful not to get carried away too much, and if you have trouble sleeping, it is better to drink a drink in the morning.

What happens after you drink coffee? The caffeine contained in the drink, the existence of which everyone already knows, enters the digestive tract, and subsequently into the bloodstream. Caffeine, in fact, is a psychostimulant, but a natural type. It has an effect both on blood pressure and on how a person perceives the reality around him. Small dosages will not allow you to notice a difference in the condition, but large doses have a strong effect on the nervous system.

Why do people drink coffee?

Despite the negative effects of large doses of coffee, a large proportion of people still drink it. And connoisseurs are not getting smaller, rather, on the contrary, an elite drink conquers more and more new people.

The reasons are quite simple, and once they taste the drink, people fall in love with its taste. There are many cooking options, with the addition of sugar and other ingredients, so everyone can choose the option that will suit their taste. Some people prefer morning coffee to wake up faster and be more alert and focused at work or at school. Often during the day, fatigue accumulates, and in the evening it may be necessary to do a lot of things, but there is no strength, and then it's time to drink more coffee, this helps to collect my thoughts and return to normal.

Naturally pleasant taste and incredibly attractive aroma, which you will hear from afar, and learn among the abundance of other smells, contribute to the popularity of coffee. Interestingly, different varieties differ in smell, Arabica smells the most pleasant, but it is far from the first in terms of strength. A number of manufacturers mix several varieties in order to achieve both strength and aroma at the same time. In a detailed study of coffee, scientists were able to detect approximately 800 aromatic compounds.

Coffee can have a special sourness or not, some drink lovers like this light bitterness the most. If desired, cream, sugar, milk will help soften the drink. Tea also contains caffeine, but coffee gives a more tangible and faster effect, which is probably why it is so in demand. Now you can buy coffee on every corner, which people enjoy with pleasure, a glass of hot drink is especially relevant in cold weather. According to statistics, coffee is one of the five most purchased products worldwide, in Japan there is even a day dedicated to the drink, October 1st.

Coffee without sugar and other additives has no calories, speeds up metabolism, makes the mood more peaceful, provokes the production of dopamine, which is responsible for pleasure in the body, and one more cup contains about 300 antioxidants.

Where does your morning start? If from a cup of coffee, without which you cannot wake up, then it's time to think about how the drink consumed by many of us in excessive quantities affects your body. There are many myths associated with the most important food "doping", but how to understand whether coffee is harmful or beneficial for you personally? Together with Anna Ivashkevich, a nutritionist and co-founder of the Beauty Ballers project, we understand what happens to the body when you give up coffee.

What is coffee?

This drink is made from roasted seeds (grains) of several types of plants, and the strength of the drink depends on the degree of their roasting. By the way, by a cup of coffee, we mean a drink prepared in a coffee machine, brewed in a Turk, or freshly ground, poured with boiling water, without adding milk or cream (this is already food, not a drink). Instant coffee does not belong here, because its strength is lower than grain, moreover, aromatic compounds and almost all useful substances are lost in it due to the lengthy processing process.

The main cons of coffee

• Coffee should not be drunk on an empty stomach because it stimulates the production of the hormone cholecystokinin, which triggers digestion. And if there is no food in your stomach, then there is nothing to digest - this process leads to heartburn and signs of gastritis.

• There are so many preservatives in coffee that negatively affect metabolism, provoke the appearance of cellulite (so it is better to use it as a scrub).

• The invigorating effect also has a downside: an hour after drinking coffee causes increased efficiency. And after an hour there will be drowsiness.

• Coffee should not be consumed by pregnant and lactating women. Caffeine accumulates in the blood of pregnant women, penetrates the placenta, leads to a decrease in the amount of iron and other mineral elements in breast milk.

• It is addictive: coffee abuse leads to dehydration, so when you drink too much of this drink, the water balance is very difficult to restore.

The main benefits of coffee

• Coffee contains antioxidants - they remove free radicals from the body that contribute to aging.

• Coffee antioxidants help fight cancer, some heart diseases, both types of diabetes and Parkinson's disease;

• Some studies prove that real natural coffee reduces the likelihood of developing colon cancer, stimulates the activity of the digestive tract.

• Coffee reduces or completely relieves headaches, as it dilates the vessels of the brain.

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

Cortisol is a key hormone produced by our body during the day - it is he who helps to wake up in the morning and fall asleep in the evening. Hormone levels are highest in the morning, and if you drink coffee at this time, the drink will block its production, which means that after a while we will want to sleep again. Typically, cortisol production occurs from 6 to 9 am, and the peak occurs at 8-9 am, so it's best to drink coffee at 10 o'clock or in the afternoon.

What will change if you give up coffee?

Despite the fact that this drink has undeniable advantages, it is not suitable for everyone. In addition, only 10% of coffee lovers do not abuse coffee, the rest, as a rule, drink an average of four cups a day, which exceeds the allowable rate.

So, if you give up coffee:

Your body will learn to absorb vitamins better

Caffeine "kills" vitamin B, reduces the content of iron, potassium, zinc, calcium in the body. And one cup of 150 ml inhibits the absorption of calcium for as much as three hours. Moreover, caffeine leaches calcium from the body, and as a result of coffee abuse, the bones become brittle.

You can lose excess weight

As we have said, caffeine increases the production of cortisol and affects the functioning of the adrenal glands. The adrenal glands work in conjunction with the thyroid gland, which takes care of the metabolism - because of coffee, it slows down and you gain weight.

Your immunity will increase

Caffeine is not our immune system's best friend, again because of the thyroid gland. The limited performance of the thyroid gland leads to a weakening of the immune system, which causes diseases. If you feel susceptible to various diseases, it is worth staying away from coffee, at least until you feel better.

You won't have liver problems

Coffee is not digested in the best way. Your liver is working to produce the enzymes that break down coffee and metabolize it. So when enzymes are needed for other harmful chemicals, the liver can suddenly get lazy. Many people who drink coffee constantly have a “lazy” liver.

You will become more energetic

Even though coffee makes you feel energized, eventually it stops working. Coffee causes the body to produce adrenaline, and if you drink it constantly, then you need more and more caffeine each time for the body to respond to it with the same efficiency.

You will feel sexier

And again about the thyroid gland. This part of our body is responsible for the hormones that control our libido, such as testosterone. So once you stop pressuring your thyroid with caffeine, you will notice improvements in your sex life.
