Harm coffee of various types - natural and soluble. How much coffee can you drink per day, so as not to harm yourself? The damage of coffee is not only in caffeine. How do digestive organs suffer from the effects of coffee? What substance, contained in coffee, harms the stomach? Why does coffee often cause heartburn? Why can not I drink coffee on an empty stomach? Can coffee lead to cancer? Why can not calcium preparations be taken with coffee? How can coffee lead to dehydration?
What kind of coffee damage is more - natural or soluble?
The fact that coffee excites the central nervous system (CNS), but simply invigorates - is known to everyone. Actually, for this, it is also drunk. Does coffee, in addition to the CNS, affect other systems or organs, for example, the gastrointestinal tract? And if it does, how? And what harm is there more coffee - natural or soluble? The dispute on this topic has not ceased for a long time, the data vary, as well as information about how much caffeine is contained in both kinds of coffee. Of course, much depends on the brand, as usual, ground, and instant coffee. The more expensive the coffee, the more caffeine is usually found in it - this rule applies to all kinds of beverages. But most, however, expensive is coffee, completely devoid of caffeine - but here the question is in the expensive technology of decaffeination.
The daily dose of caffeine has long been established and it seems that everyone is recognized - 300 mg per day - a dose that does not harm a healthy person. In a glass of 250 ml of ordinary, ground coffee, caffeine contains between 180 and 250 mg. It turns out, a couple of cups only and you can drink. But the numbers of caffeine in soluble coffee all lead different, and it is difficult to test them - from 90 mg to 200 mg (and even more) in 200 ml. But in any case it is understandable - all that more than a glass is already on the verge and with the abuse of such doses, the harm of coffee will not take long.
Harm coffee. The stomach takes the first blow!
Is it only the caffeine content that determines the harm of coffee? No, and basically, if we talk about the digestive organs - stomach, liver and pancreas, caffeine is inferior in terms of the degree of damage caused to chlorogenic acids contained in coffee. They determine the acidic environment of the drink, it is from them that people develop heartburn after drinking coffee, they lead to irritation of the gastric mucosa, which leads to excessive formation of hydrochloric acid and its effect directly on the stomach mucosa.
That's why it's so bad to drink coffee in the morning on an empty stomach. After all, during the night our stomach was freed from food and ready for the beginning of a new "working" day, and an unexpected irritant is suddenly poured into it. But even more harm to coffee can be obtained if you drink coffee and do not eat anything - because then hydrochloric acid, when allocated, has nowhere to be consumed, and it will digest its own stomach tissues. This process, which is repeated often (and the habits of the coffeemans do not change for decades) leads to a minimum of gastritis, often to the ulcer process, well, and the ulcer, untreated, with uneven, dense margins and tuberous bottom is already the subject of research on oncology science. Simply put, there will already be talk about stomach cancer.
Soluble coffee for the stomach is most harmful - as decided in recent years by most scientists of the world. And different in the processing of coffee beans, drinks are the same in effect on the body - that powder, that granulated, that sublimated coffee. And in a drink brewed from ground coffee, the most harmful is the thick, which contains tannins, leading to all the above processes. Therefore, if you really drink coffee, then only a coffee maker with a filter, and it is better to use disposable filters.
The harm of coffee, drunk on an empty stomach is very strong, but when is it best to drink coffee? It turns out that it is best to drink coffee after eating, but not immediately. If you immediately drink coffee eaten food, then mixing with it, coffee significantly disrupts the initial process of food processing with enzymes of the stomach and causes significant harm to digestion. Optimum, if coffee gets into the stomach an hour after the main meal. This time is the "height" of digestion and the isolated hydrochloric acid will be included in the process. Apparently, the ancient rule, according to which coffee served after a meal, while covering a separate table, not where they had dinner, but in another room, was not just a beautiful tradition, but also a tribute to the preservation of health.
Harm to coffee is applied to metabolism
Different sources estimate coffee in different ways in terms of its carcinogenic properties - there were even publications about coffee as a useful antioxidant, protecting us from the diseases of civilization. But the Harvard school of physiologists - quite trustworthy scientists - consider coffee just the cause of development of oncological processes not only in the stomach, but also in the liver, pancreas and even in the bladder. And these studies are quite serious. The liver also perceives coffee, even being healthy, as a poison of irritating action and consequently struggles with it. With a long struggle, the harm of coffee becomes inevitable, the reserves are depleted and the development of liver metabolic lesions becomes possible, for example, fatty degeneration.
What other harm to coffee is being brought to the human exchange processes? The drink itself does not carry in itself special minerals or vitamins, but categorically interferes with the absorption of some useful macroelements, for example, calcium. Therefore, to drink calcium preparations should be either an hour before coffee, or two hours after taking coffee (tea, this rule also applies, because it also contains caffeine - it is this substance that binds to calcium, it forms insoluble and therefore not assimilated by the body connections) . Coffeemania, especially in adolescence, leads to early development of osteoporosis due to a lack of calcium, and this affects the figure and posture of quite young people.
Coffee arouses appetite, this is also well known. Because most if not all diets require those who are going to apply them, a complete rejection of coffee, since even with the use of a small cup "for vivacity" many diets do not work! In addition, coffee is a diuretic. This is a fact not in doubt. And taking diuretics is a serious matter, often not always and shown to everyone. Therefore, the harm of coffee with its abundant and frequent use, leads to dehydration of the body.
There is one more detail - coffee dulls the thirst, it happens at the level of the brain, and the dehydrated body does not signal a serious problem. Man does not want to drink! So it turns out - some people, forced or determined to calculate how much and what they drink during the day, are horrified to realize that they only drink coffee all day - a few cups, and nothing more. In such a regimen, the harm of coffee will definitely manifest itself, since the diuretic properties of the drink affect far from the best way and on the kidneys (they are constantly "spurred on" unnecessarily). In addition, for pressure and cardiac activity, dehydration is harmful, but, like other diuretics, caffeine releases potassium, disrupting the smooth functioning of the heart, leading to dystonia and hypoxia of the brain.
Here comes the paradox - we drink coffee to raise the pressure, and first increase, but then, due to the diuretic effect, we lower again. Such "swings" are poorly tolerated by man, and suffering from vegetative-vascular dystonia, in which everything is "unbalanced" - even more so. That's why it's customary in the east, but for some reason it did not get used to us - to serve a glass of plain clean water for coffee - how much coffee has been drunk, so much water has been added!
This is how the aromatic coffee drink acts on the gastrointestinal tract and human metabolism.
