Coffee: to drink or not to drink?

Arabica and Robusta beans are called coffee. The first has a milder taste, the second is bitter. But both are rich in antioxidants and caffeine, which protect cells from toxins and harmful substances. However, everything should be in moderation.

Back in 2015, the European Food Safety Authority recommended no more than 400 mg of caffeine per day and no more than 200 mg at a time. For example, a serving of Americano contains 154 mg of caffeine, while an espresso has 77 mg.

How does coffee affect our health?

Coffee and heart

Coffee damages our heart and blood vessels. Myth or Reality? Some studies have shown that regular indulgence in coffee leads to stiffness of the aorta – the largest blood vessel in the human body. This is what causes the development of cardiovascular diseases.

At the same time, drinking up to three cups of coffee a day reduces the risk of death from heart disease. This was confirmed by the results of one study published in the journal Annals of Internal Medicine.

Another study also found no difference in cardiovascular health between those who drink more than three cups a day and those who drink one. Scientists have concluded that even significant consumption of coffee is unlikely to harm the health of the arteries and heart. As you can see, the opinions of the luminaries of science were divided.

Natalia Korchma, a cardiologist at the ON Clinic Kharkiv medical center, notes:

“Coffee improves the condition of blood vessels, which is an excellent prevention of atherosclerosis. At the same time, the drink can cause tachycardia. To understand how coffee works on your heart and body in general, listen to the sensations. There shouldn’t be any discomfort ”.

If after coffee there is nausea, palpitations, headache, then the body does not tolerate caffeine well. In this case, adjust the dose of caffeine or exclude it for a while, or better, replace it with healthy and aromatic chicory. If you drink coffee with additives (sugar, cream, milk), then, according to scientists, they increase the calorie content and fat content of the drink, which reduces its benefits.

Coffee and teeth

Coffee darkens the enamel. Unfortunately, this is not a myth, but a reality, which many dentists would agree with. However, this only happens if there are microcracks in the teeth. But even if you drink the drink through a straw, trying to protect your teeth, contact cannot be avoided. Therefore, it makes no sense to be sophisticated.

It is also true that drinking coffee with sugar contributes to the destruction of tooth enamel. Sweet food provokes the accumulation of pathogenic microbes, which accelerates the process of plaque formation. And I also do not advise you to combine coffee with ice cream. It is from the combination of hot and cold that microcracks can appear on the teeth.

For those who have already decided to brush their teeth immediately after drinking coffee, it is better not to do this. Hot drinks soften tooth enamel and is easier to damage during brushing.

By the way, Italian scientists have proven that roasted coffee has high antibacterial properties and protects the oral cavity from bacteria of the genus Staphylococcus aureus and Streptococcus mutans. According to this characteristic, even green tea loses to the drink. So, to avoid dental problems, it is enough to visit the dentist regularly and take care of the oral cavity.

Coffee and bones

The myth that coffee washes out calcium can also be partially true, but in the event that a person does not consume the daily dose of calcium and vitamin D (thanks to it, calcium is absorbed). This conclusion was reached by many scientists from around the world.

For example, Korean scientists investigated the relationship between coffee consumption and bone health in young Korean men between 19 and 26 years old. The study found that people with a calcium deficiency who consumed small amounts of coffee had lower bone and bone health scores than those who drank coffee and consumed an adequate dose of calcium.

However, scientists have not made any definitive conclusions other than that in connection with the increase in daily consumption of coffee in modern life with a calcium deficiency in the diet, further research is needed on this issue.

The benefits and harms of milk: which is more?

milk or cream added to coffee. There is no scientific evidence for this. On the contrary, the scientists concluded that the consumption of caffeinated beverages is not associated with a decrease in bone mass and fragility of the skeleton, which can lead to fractures.

Caffeine only slightly inhibits calcium, which is absorbed in the intestines, and the addition of dairy products, like their absence in coffee, cannot affect the state of bones. Their fragility is due only to a lack of calcium in the diet. However, for many, coffee is only the culprit for the fact that, in fact, the human diet is far from a balanced diet.

Coffee and oncology

There is a myth that coffee causes cancer. However, the International Agency for Research on Cancer of the World Health Organization notes that there is no strong evidence for this claim. Although coffee does contain a carcinogen – acrylamide. However, the same substance is found in potatoes, potato chips, hot toasts, and even cereals.

The researchers note that very hot drinks may be carcinogenic. As a rule, these are those whose temperature exceeds 65 degrees. The fact is that, getting inside a person, they are able to destroy the cells of the esophagus and act as a catalyst for tumors. However, this is just one study and food for thought for very hot coffee lovers. Traditionally, coffee is served at a temperature of 60-75 degrees. If the drink burns the lips, then it will be advisable to cool it slightly.

Despite this, in the spring of 2018, a California court ordered American coffee producers to put labels warning about carcinogens in coffee. Even the well-known company “Starbucks” could not prove to the court that the substance formed during the roasting period of coffee does not increase the risk of developing cancer.

On the contrary, the result of one study in which scientists took part in Italy, the UK and the USA proved that moderate consumption of coffee is associated with a decrease in the risk of breast, colon, endometrial and prostate cancer. Also, thanks to its use, there is a possibility of reducing the risk of developing Parkinson’s disease and diabetes of the 2nd degree. Moreover, scientists have concluded that coffee can even be part of the diet.

Coffee and pregnancy

They say that pregnant women should not drink coffee. There is some truth in this. After all, caffeine provokes an increase in blood pressure, and pregnant women, like hypertensive patients, do not need it at all. But we must remember that pregnancy is a special condition in which everything is individual.

The British health service advises pregnant women to drink no more than 200 mg of caffeine per day. The reason is simple: caffeine can provoke a miscarriage, since it has an exciting effect on the nervous system, and high blood pressure can lead to gestosis (late toxicosis, which usually occurs in late pregnancy).

Inna Rozmus, a gynecologist at the ON Clinic Nikolaev medical center, recommends:

“The question of whether and when to add coffee to the diet during pregnancy should always be discussed with the attending gynecologist. Unauthorized use of the drink can have serious consequences for both the mother and the baby. If there is no danger to health, the doctor does not prohibit the use of coffee in moderation. ”

Norwegian scientists have found that excessive consumption of coffee by pregnant women leads to obesity in their children in the future (under the age of 8). The same goes for strong teas and chocolate, as they also contain caffeine.

The World Health Organization claims that caffeine is an aphrodisiac and is found not only in coffee, but also in medicines, energy drinks and nuts. But one of the reasons for excessive amounts of caffeine in the body is drinking coffee. The excretion of this substance from the bloodstream of a pregnant woman occurs very slowly, which affects the growth of the fetus, can lead to premature birth and stillbirth.

Ground or instant?

Ground coffee is roasted and then ground coffee beans. Soluble is boiled in different ways, but sublimation (drying at a low temperature in a vacuum) is considered the highest quality. However, this is an expensive pleasure and instead of granules as in freeze-drying, the coffee is simply dried. It is this coffee that we are used to seeing on supermarket shelves in the form of a fragrant dry powder.

There are opinions that coffee beans are healthier. After all, instant coffee from unscrupulous manufacturers may contain additional impurities (for example, substances that increase shelf life).

However, some experts believe that instant coffee is no different from ground coffee. After all, it is only a matter of production technology: coffee beans are ground and dehydrated. Therefore, the only difference between coffee beans and instant coffee is the caffeine content. On average, in a cup of instant coffee, depending on the type, the caffeine content is in the range of 60-80 mg, freshly ground – 60-120 mg.

Did you know that Luwak coffee is considered the most expensive type of coffee? Musang, the Malayan palm marten, is involved in its production. The most delicious coffee drink with a chocolate-caramel flavor is obtained from the excrement of this animal: the animal feeds only on coffee beans.

Coffee and alcohol

Doctors do not recommend drinking coffee with alcohol because of their opposite effect on our body. The first one tones up and constricts blood vessels, the second one relaxes and expands. The result is a conflict of interest.

However, some studies say that this combination is not very harmful to health, but is not able to ensure the safe driving of vehicles or activities requiring increased attention. There is no evidence that sharing these drinks can lead to sudden death due to heart problems or the development of alcohol dependence (for example, latent

Alcohol abuse

Alcohol abuse


Personally, I find coffee invigorating, energizing, and even improving athletic performance, but in moderation. It plays the role of a stimulant, but not every person has a beneficial effect and this must be taken into account. If you have a problem with coffee, you need to choose a different drink. If it’s okay, just don’t get carried away.

What kind of coffee do you like and why?
