What harm can daily consumption of coffee do to the body and is there any benefit from it. How three cups of coffee a day prolongs our lives Drink 3 cups of coffee
For many years, coffee caused controversy: scientists doubted whether constant caffeine intake on human health.
Recent studies will please everyone who is crazy about this aromatic drink - coffee not only does not harm, but also benefits the body.
Useful properties of coffee quite unexpected and noteworthy. A striking example of this is the effect of coffee on the liver.
Liver and coffee have always been antagonists. Who has not heard that coffee is a very heavy product for the liver? According to the conclusions that were made by scientists after observing people suffering from liver diseases, coffee can be called a medicine.
Useful properties of coffee
This drink lowers the level of liver enzymes in the liver and slows down the scarring of the liver tissue. Patients with hepatitis C are advised to drink coffee so that the disease does not progress. This applies not only to regular coffee, but also to decaffeinated coffee! The only product that is definitely not worth using is instant coffee, it does not bring benefits, alas.
The National Cancer Institute (Maryland, USA) conducted a study, the results of which indicate that coffee slows down the growth of cancer cells and also reduces the rate of development of liver cirrhosis caused by hepatitis C.
Lower insulin levels and less severity of fatty liver were found in all patients who consumed adequate amounts of coffee. The experiment was conducted for almost 4 years, during which time scientists were convinced of the undeniable benefits of coffee.
But coffee is an amazing product. It is useful not only for the liver. Coffee contains the same high amount of antioxidants as fruits and vegetables! If you are afraid of catching some kind of infection during the spring beriberi - drink coffee more often. Coffee is anti-inflammatory and prevents the development of infection.
Coffee lowers blood sugar, so people who regularly indulge in this drink protect themselves from diabetes second type. Of course, it is not recommended to combine coffee with fatty and sweet foods, this causes blood sugar spikes. It is better to drink coffee with milk or add light snacks like nuts and dried fruits to your favorite drink.

If you have depression, or a breakdown, or simply no mood, if you have problems with metabolism, cardiovascular, circulatory, digestive, nervous systems, you need to drink coffee. But no more than three cups a day.
This conclusion was reached by British scientists who conducted a study in ten European countries that lasted 16 years. More than half a million participants aged 35 and over drank varying amounts of natural coffee daily. Some of the volunteers did not drink coffee at all.
Life with and without coffee
The worst results were shown by the health of those who did not drink coffee. They were slightly better for those who drank more than three cups a day. The best health indicators were found in those who consumed two to three cups of coffee a day.
It was in the latter group, according to the results of the study, that the risk of death from a number of diseases was significantly reduced. First of all, these include diseases of the circulatory and digestive systems. True, in men, the risk reduction, compared with those men who did not drink coffee at all or drank a lot of it, was 18 percent, and in women (a similar comparison with ladies) - only eight.
With or without caffeine
Mark Günter, one of the researchers, stressed that the results were the same for representatives of all ten countries. What's more, there was no difference in health effects between those who drank decaffeinated coffee and regular, caffeinated coffee.
It did not matter either the tradition of preparation, or the type of coffee consumed, or the types of this drink - espresso, cappuccino, latte and others.
Beneficial Antioxidants
The results of this study, published in the scientific journal Annals of Internal Medicine, suggest that the antioxidants in natural coffee are the most beneficial. It is no coincidence that among coffee lovers there are a large number of smokers, as well as those who do not deny themselves the pleasure of skipping a glass of alcoholic beverage.
In addition, among these people there are more of those who prefer a good piece of meat to vegetables and fruits. However, all this - in the opinion of doctors, which is harmful to the human body - did not affect the health of coffee lovers. Moreover, they all felt younger than their years.
Relaxing coffee
Scientists from the University of Southern California came to almost the same results. True, about 190 thousand people participated in the study among Americans, including Hispanics, Europeans, Japanese, and African Americans living in the United States.
The figure of 18 percent also appears here - the risk of death from cardiovascular diseases is so reduced among those who drink two or three cups of coffee daily. But those who drank only one at a time - the risk of death decreased by only 12 percent.
The Americans also found that men who consumed two to three cups of coffee daily reduced the possibility of erectile dysfunction by 42 percent. Coffee has a relaxing effect on the arteries, which leads to improved blood flow to the male reproductive organ.
Gastritis and ulcer
You can talk about all the positive consequences of moderate coffee consumption for a long time. However, we must not forget that it also has its drawbacks. For example, due to the characteristics of an individual organism, coffee can adversely affect the gastric mucosa.
The result can be gastritis and even an ulcer. And for those who already have similar diseases, it is better to refuse coffee, at least until complete recovery.
Caffeine raises cortisol levels. If you keep it always elevated, then you are at risk of obesity, as cortisol helps fat accumulation. Pregnant coffee drinkers double their risk of miscarriage.
Coffee is also addictive. If you are a devoted fan, try to stop drinking coffee abruptly. The consequences in the form of not the best sensations will not be long in coming.
Coffee drinkers who drink about three cups of coffee a day are more likely to live longer than non-coffee drinkers, scientists have found.
According to a study conducted by the British Agency for Research on Cancer and Imperial College London, more frequent coffee consumption reduces the risk of death from a number of diseases.
Scientists argue that the relationship between coffee consumption and a reduced risk of death from diseases of the circulatory system and digestive organs is most obvious.
This is one of the largest studies of its kind. More than 500 thousand people over 35 from 10 European countries took part in it. They were followed up for 16 years. The study was published in the scientific journal Annals of Internal Medicine.
"We found that drinking coffee reduces the risk of death, especially death from diseases of the circulatory system and digestive organs." - says one of the researchers Mark Gunter from the Agency for Research on Cancer.
Is any coffee good for you?
The scientists emphasize that, despite the different traditions in the preparation and consumption of coffee in different European countries, the results were actually the same in all regions. This means that both espresso and cappuccino can be considered equally healthy.
Among Europeans, the Danes drink the most coffee per day - an average of 900 ml per day, the least of all drink it, oddly enough, the Italians - 92 ml per day.
"Our study provides important insights into the possible mechanism of coffee's health benefits," he said.
As scientists suggest, this effect is not given by the caffeine contained in this drink. The study just did not reveal any relationship between improved health and the habit of drinking decaffeinated coffee. The results of those who drank regular coffee and decaffeinated coffee were the same.
It's not about the caffeine
According to the researchers, it's all about the antioxidants in coffee.
As it turned out, those who were used to drinking a lot of coffee felt younger, and, as a rule, they were more likely to drink alcohol, smoke, and also ate more meat and less vegetables and fruits.
Of the study group, almost 42,000 people died in 16 years from various diseases, including cancer, diseases of the circulatory system and heart attacks.
As it turned out, men who drank more coffee had an 18% lower risk of death than those who refused coffee or drank it in small quantities.
Among women, this effect is less pronounced: the risk of death for them was 8% lower than for women who drank coffee in small quantities or completely refused it.
Another study
A similar study was conducted by American scientists from the University of Southern California - its results were also published by the Annals of Internal Medicine.
In total, more than 185,000 people of different ethnicity took part in the American study - Hispanics, African Americans, Japanese and Europeans living in the USA.
It is important that the results of the study by scientists from the United States were similar to the findings of their British colleagues.
According to an American study, people who drink one cup of coffee a day had a 12% lower risk of dying from cardiovascular diseases, stroke, cancer, respiratory and kidney diseases.
Those who typically drank two to three cups of coffee a day had an 18% lower risk of death.
Coffee regularly becomes a stumbling block between people advocating a healthy lifestyle. On one side of the barricades are those who suggest giving up coffee, blaming the drink for its ability to increase the risk of heart disease. On the other hand, those who believe that there is nothing wrong with moderate coffee consumption, and that a “cup of vigor” has not harmed anyone yet.
It would seem that scientists should resolve the dispute with their numerous studies on the topic. But here's the problem: studies show that coffee is both harmful and beneficial at the same time. However, there are still more votes “for” drinking coffee in small quantities, as scientific experiments confirm that a drink based on coffee beans can increase brain activity and even.
More recently, scientists have found that three cups of coffee a day prolong life. And this is another reason not to deny yourself the pleasure of espresso (more precisely, three at once).
The Daily Mail reports that two large research groups have independently concluded that drinking 1-3 cups of coffee a day markedly reduces the risk of early death. Research results published in the Annals of Internal Medicine show that there is a strong relationship between coffee consumption and a reduced risk of liver disease, circulatory problems, and diseases associated with the digestive tract.
The study, conducted by Imperial College London and the UN International Agency for Research on Cancer, involved 520,000 people over the age of 35 from ten countries. The results showed that volunteers who drank three cups of coffee a day had an 18% increase over 16 years, compared to those who drank no coffee at all.
The American study, led by experts from the University of Southern California (University of Southern California), analyzed the data of 186,000 people. The results were similar: people who drank one to three cups of coffee a day were 12% to 18% less likely to die over the next 16 years, compared to those who gave up coffee.
Scientists believe that the reason is in antioxidant plant compounds, and not at all in caffeine, as you might think. In addition, a number of indicators allow us to say that they (antioxidants) effectively relieve inflammation in the body and.
"Importantly, the results were similar in all ten European countries with different coffee drinking habits and customs," says Marc Gunter, lead author of the first study. Thus, moderate coffee consumption really does not harm the body, and including the drink in the diet obviously has real health benefits.
Coffee drinkers are amazing people.
They are distinguished by enviable vivacity, harmony and longevity, contrary to the previously widespread opinion about the dangers of a grain drink.
It's all about quantity and quality.
How much coffee can you drink a day: count the cups
The average safe indicators of the norm approved by doctors are from one hundred to two hundred milligrams of caffeine at a time. Three teaspoons of natural ground coffee or two tablespoons of instant coffee are safe, which can be contained in one cup of the drink. The daily dose is two to three such cups. This is the question of how much coffee you can drink a day.
You need to understand the difference between a safe dose of caffeine and the benefits of real coffee. Yes, two cups of an instant drink per day will not bring much harm to the body, but you can’t expect any benefit from them either.
Another thing is natural ground grains of proper roasting. Just now brewed coffee can be a real elixir. Contrary to popular belief, it does not increase, but reduces blood pressure, normalizes weight, prevents senile dementia, cancer and other diseases. However, exceeding the recommended dose can be fatal to health.
Here are the data obtained by scientists in the study of a popular grain drink (we are talking about natural, not freeze-dried coffee in the amount of 100 mg of caffeine per cup).
1. One cup a day promotes healthy arteries, lowers blood pressure and does no harm.
2. Two cups a day can prevent Alzheimer's disease - the scourge of our time.
3. Three cups reduces the risk of ovarian cancer, prevents gallstone disease. On the other hand, three cups of coffee a day can already be said to be a health risk: this amount of caffeine increases the risk of a heart attack.
5. Five cups a day, according to some scientists, reduces the risk of liver disease, but contributes to the development of osteoporosis.
6. Six cups is overkill. However, natural coffee contains antioxidant substances, so scientists suggest that 600 mg of caffeine can protect against skin cancer. The retribution for an overdose is dehydration, irritable bowel syndrome, hypertensive crisis, heart attacks, mental disorders (fear, depression, etc.).
To answer the question of how much coffee you can drink per day, it is enough to correlate the benefits and harms of the drink with your state of health. Despite the undoubted advantages of a coffee diet, you should not exceed a safe dose of coffee.
In general, the drink stimulates the activity of the brain and the body as a whole, protects teeth from caries, accelerates metabolic processes, increases efficiency, expands and strengthens blood vessels, and has a beneficial effect on the liver, heart, and endocrine system.
How much coffee can you drink a day: how much caffeine is there?
The ingenious Balzac could not imagine his life without coffee and drank every day ... at least 40 cups of an invigorating drink! For an ordinary person, this amount of caffeine is a real poison. How much coffee can you drink per day? Here is a question that is really important to find the right answer.
In fact, it is not the cups that need to be counted, but the amount of caffeine contained in a serving. It is he who poses a health hazard. Therefore, there is a difference what kind of coffee to drink: fiery espresso or watery Americano. Here's how to calculate your daily dose (caffeine amounts are per small and large medium cup):
Cappuccino - from 70 to 80 milligrams;
Espresso - from 80 to 135 milligrams;
Homemade Turkish coffee - from 115 to 175 milligrams;
Soluble with caffeine - from 65 to 100 milligrams;
Soluble without caffeine - no more than 4 milligrams.
The amount of caffeine is influenced by many additional factors, from the variety to the method of preparation of the drink. There are ways to lower your caffeine factor. The most common and delicious - just add milk to the drink. Due to the milk component, the effect of caffeine becomes less aggressive.
The concentration of caffeine becomes lower if you drink water immediately after a cup of coffee. That is why in good cafes and restaurants, a glass of water is always served with coffee.
A great way to reduce caffeine levels when making homemade Turkish coffee beans is to use hot water to soak the beans. The cap of foam rises faster, less caffeine is released. You can additionally strain the drink through a strainer so that there is no thick.
How much coffee can you drink a day: a complete ban?
What is the risk of a person who drinks coffee? At a minimum, he may develop chronic insomnia, headache, hand tremors, increased irritability, and fatigue. These are all signs of caffeine poisoning.
A complete ban on coffee should be introduced for people diagnosed with serious diseases: diabetes, stomach ulcers, gastritis, pancreatitis, any diseases of the cardiovascular system, hypertension.
An instant coffee drink is not the best choice for perfectly healthy people either. Not only does it not contain useful substances, minerals, tannins, vitamins, organic acids, tannins. The thing is that only a quarter of such a product can be considered real coffee. Everything else is preservatives, dyes, corn starch and other food waste.
Decaffeinated instant coffee is generally a misunderstanding, since there is not even caffeine, but harmful food chemistry is present in abundance. If there is no choice, then it is better to buy more expensive varieties, always in a glass or metal jar.
How much coffee can you drink a day if only instant drink is available? The safe amount is just one cup of instant coffee, regardless of the presence or absence of caffeine.
