Influence of coffee on the human body: features, properties and recommendations of specialists

People love coffee since ancient times. This drink has many fans, but there are many who are convinced of the exceptional harm of coffee for the body. The truth is, as usual, somewhere near. What is the effect of coffee on the body? Let's understand!

There are different types of raw materials. The classic is made from roasted coffee tree grains. The effect of soluble coffee on the body is somewhat different, because this drink has a different composition. Another species is green grains, of which there are many myths.

Composition of the product

The main ingredient is caffeine. It is distinguished by an exciting action, 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, accelerate the transmission of nerve impulses.

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

And roasted coffee beans contain:

• Tannins - give a bitter taste;
• Caffeol (this component enhances blood circulation, lowers cholesterol);
• Vitamin P, necessary for the walls of blood vessels;
• Chlorogenic acid (important for protein metabolism);
• Essential oils that provide a unique flavor and taste.

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

Many have heard of the theobrom in coffee. The effect on the body of this component is similar to that 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 overstrain, drowns out pain, allows you to concentrate and find the right solution. But if you want to improve your health with theobromine, look for it in cocoa or chocolate: in most types of coffee, in fact, there is practically no this substance.

Effects on the heart and blood vessels

Drinking a drink briefly increases blood pressure. Immediately pulse quickens. But there is a nuance.

The coffee makers who regularly drink their favorite beverage, this effect is not observed. But those who drink it very rarely, even the bezofeyinovy drink increases blood pressure. More doctors noticed that the lowered pressure of coffee increases, but the normal - no. Clinical studies have confirmed that people who drink about 5 cups a day have practically no problems with increased or decreased blood pressure. But it is worth to increase the number to 6 cups, as persistent hypertension is guaranteed.

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

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

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

Influence on the nervous system

Caffeine also stimulates nervous activity: working capacity increases, fatigue decreases, a feeling of vivacity comes, the thinking process becomes more active.

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

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

• Lethargy;
• drowsiness;
• prostration;
• Retardation;
• Depressive states.

Influence on the genitourinary system

This drink has a pronounced diuretic effect. It is necessary to monitor the amount of liquid consumed. Regularly replenish fluid loss, especially in hot weather. 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.

Effects on the digestive system

To drink on an empty stomach is undesirable. With caution should be taken to drink a patient 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 - the peristalsis is activated.

Effects on the liver

At present, scientists do not have data on the negative effect of coffee on this body. But for bilious coffee is useful. Only a few cups a day help to clear the ducts, which serves as an excellent prevention of cholelithiasis.

Coffee and metabolism

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

It is considered that coffee causes dependence, but scientists assure that it can only go about psychological predilection. Stop drinking coffee - and perhaps you will feel sad for the pleasant moments that he gave you in the morning or during the break. But you will not feel any breaking.

Under the big question and carcinogenicity. Coffee is assigned to the third group (substances about which data are insufficient 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. Currently, this issue is being actively investigated.

It is worth mentioning the effect on cholesterol. The drink indirectly affects the metabolism of fatty acids, lowers cholesterol.

Instant drink

It is considered that this option is safe, but in fact, the effect of soluble coffee on the human body exceeds the effect of natural varieties. This is due to the increased content of caffeine.

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

One should 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 prepare a delicious and healthy drink and from unroasted grains. This product is popular with those who want to lose weight. The taste and smell of it are not as expressive and pleasant as the familiar classic cooked in a Turk. But useful substances in grains, not subjected to roasting, more.

Components of green coffee really disperse the metabolism, which contributes to weight loss. In addition, the drink helps to restore strength for a new workout. But do not expect that the result will come of itself: green coffee only promotes weight loss, and does not cause it in a magical way. Kilograms will go away, but for this you need to try, combining the right food with reasonable fiznagruzkami.

Influence of coffee on the female body

There is an opinion that regular consumption of a natural drink reduces the risk of becoming pregnant. This drink can not be considered a contraceptive, but it is better for women who are trying to conceive a child to reduce consumption to a minimum.

Pregnant coffee is not recommended. Its negative impact on the fetus is a proven fact.

Investigating the effect of coffee on the woman's body , scientists found a link with the formation of breast tumors. Benign formations can dissolve by themselves, it is only necessary to reduce caffeine intake.

During menopause, the harm of coffee is associated with the washing out of calcium. During the lactation period, the drink is especially undesirable for the same reason.

If there is a benefit to this drink for the woman's organism, at present it is not known about it. However, scientists have confirmed the promotion of slimming natural coffee varieties for a long time.

Influence of coffee on the body of a man

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

But do not be addicted to this drink. Excessive use can lead to an increase in the level of estrogen (female sex hormones). In this regard, instant coffee is also more dangerous than natural coffee.

There is an opinion that coffee can provoke the progression of prostatitis.

As it is necessary and as it is impossible

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

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

Do not forget that you can not abuse this drink categorically. Overdose can even lead to death. 15 or more cups of coffee per day will invariably cause a number of negative consequences. They 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 exciting. A pair of evening cups can turn into insomnia.

As we see, coffee can not cause special harm if you drink this drink within reasonable limits.
