Below are diseases in which coffee beans are not prohibited, on the contrary, they are recommended for use.

Liver cancer

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!

There are different types of 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 a 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 high or low blood 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: a 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 metabolism of 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 make a delicious and healthy drink from unroasted grains. Such a product is popular with those who want to lose 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 physical activity.

The effect of coffee on the female body

There is an opinion that regular consumption of a natural drink reduces the risk of becoming 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.

Investigating the effect of coffee on the body found a connection with the formation of tumors of the mammary glands. Benign tumors can dissolve on their own, it is only necessary to reduce caffeine intake.

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.

Do not forget that it is absolutely impossible to abuse this drink. An overdose can even lead to death. 15 or more cups of coffee per day will invariably cause a number of negative consequences. These include the following:

• hallucinations;
• neurotic phenomena;
• vomiting;
• tachycardia;
• pain in the stomach;
• convulsions;
• temperature increase;
• shortness of breath

Be careful at the end of the day. The effect of coffee on the body, as we already know, is stimulating. A couple of evening cups can turn into insomnia.

As you can see, coffee cannot cause much harm if you drink this drink within reasonable limits.

Coffee is a drink that contains caffeine and it owes its name to it. Caffeine is a substance that can cause excitation of the central nervous system. As a result, coffee helps to wake up in the morning and acts invigoratingly. However, in too high doses, caffeine can be dangerous - it can lead to overexcitation, insomnia, even paranoia, and if abused excessively, panic attacks.

But that's not all, there are other benefits from natural coffee: reducing the harm from smoking, hanging the effectiveness of antibiotics, and accumulating the hormone of happiness in the human body. The main component that has a positive effect on some mechanisms in the human body is caffeine. It can be useful in some quantities, but if consumed in excess, it can harm the human body. That is, coffee can be both useful and harmful to humans. Let's take a closer look at the harmful properties of coffee.

Harm coffee

1. With frequent use of coffee, it 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 is quickly depleted. The normal functioning of all mechanisms of the body is disrupted, which leads to stress. Excessive consumption of coffee can cause attacks of aggression and psychosis, so you should not drink it too often.

2. Black coffee harms the cardiovascular system. Stimulation of the cardiovascular system due to the action of caffeine is short-term. After drinking coffee, a person's blood pressure rises and the 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 the patient, but also a healthy person if it is consumed excessively. So that coffee does not harm the heart and blood vessels, people with cardiovascular diseases are generally not recommended to drink coffee, healthy people are advised to drink coffee in moderation, no more than 2-3 cups a day.

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

For example, the lack of a sufficient amount of calcium in the body leads to the destruction of teeth, fragility of bones and nails, problems with the spine may appear in the form of curvature, osteochondrosis, and back pain. It is especially harmful to drink a lot of coffee in adolescence, when the musculoskeletal system is just being formed, and the lack of calcium can lead to its improper formation. Lack of vitamins B1 and B6 can lead to cerebrovascular accident, which can cause headaches and a number of other diseases associated with mental activity, attention, speed of reaction.

It is harmful to drink coffee during pregnancy, as the fetus may not receive the above trace elements that coffee washes out of the woman's body, which can lead to developmental disorders in the child.

4. Coffee is addictive when consumed frequently. People with coffee addiction may experience symptoms such as fatigue, depression, depression 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 with its frequent use it leads to mental disorders such as paranoia, epilepsy, psychosis. Coffee stimulates the active work of the cardiovascular system, and if a person is in this state often, then stress appears. Due to being in constant stress, a person becomes aggressive.

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

7. Coffee has a dehydrating effect on the body, is a diuretic. Therefore, along with coffee, it is recommended to drink plain water. To replenish the water supply in the human body. To maintain the balance of water in the body, it is recommended to drink water in the amount of coffee drunk.

Coffee can be both beneficial and harmful to humans. It all depends on the characteristics of the body and the amount of coffee consumed. A healthy person can drink 2-3 cups of coffee a day and there will be no harm from this. But if a person has hypertension and vascular disease, then it is not advisable for him to drink coffee. Asthmatics also benefit from drinking coffee, consumption of 2-3 cups will help improve breathing, slightly reduce the strength of the attack.

Black coffee is a drink that actively affects the human body, so you can drink it in small quantities, only in this case its consumption will be beneficial for a person. Frequent and oversized consumption can harm a person, so if you drink a lot of coffee, we strongly recommend that you reduce your dose in order to maintain your health.
