Bad news for coffee lovers: your favorite drink negatively affects your intestinal microflora. Excessive coffee consumption can cause dysbiosis. But there is also good information: thanks to coffee, the intestines begin to actively contract, helping to remove undigested residues from the body - the so-called toxins.

American scientists from the University of Texas were interested in the effect of coffee on intestinal tissue. They were able to establish that regardless of whether the drink contains caffeine, coffee is able to activate intestinal muscle tissue, but at the same time inhibits the activity of intestinal bacteria.

Intestinal microflora reacts negatively to coffee

The studies were conducted on laboratory rats who were given coffee for three days: one group was regular coffee, the other was decaffeinated. The fecal masses of the rodents were sent to the laboratory to study the bacterial composition of the intestines. At the end of the experiment, the quantitative composition of the microflora decreased significantly in both groups of animals.

After this, studies were carried out on samples of intestinal microflora. Scientists exposed cultures of intestinal bacteria to coffee solutions with a concentration of 1.5% and 3%. Inhibition of bacterial activity was noted in both cases, regardless of the concentration of the drink. Unfortunately, the researchers did not find out which types of bacteria were most sensitive to the drink - beneficial or pathogenic. This remains to be seen in the next series of experiments.

Skin condition

This drink can change it. And not for the worse, by the way. Numerous studies have proven that coffee can protect the epidermis from photoaging and age spots, as well as from such an unpleasant disease as rosacea. And some scientists even claim (and present the results of their research) that coffee has some preventive effect against skin cancer.

True, the issue of acne remains not fully understood. Many claim that the coffee drink (or rather, its abuse) has something to do with them. But how is still a mystery. They say that coffee can worsen the effects of existing acne. This is due to caffeine, which gives you an alert but also increases the human stress response by increasing levels of the hormone cortisol, which is responsible for all acne woes. The sebaceous gland secretes a lot of sebum against such a hormonal background, and if there are already disturbances in this area (clogging + microbes), the condition will definitely worsen.

In this matter, it also matters how much coffee is drunk and with what exactly. If with a lot of sweets, this will certainly affect the condition of the skin. The connection between sweets and acne has long been proven. In addition, cream and milk can negatively affect the skin of people with lactose intolerance.

The healthiest option, as always, is moderation. No more than 2-3 cups of coffee per day. And you can even add a spoonful of sugar each.

Coffee activates the intestinal muscles

The effects of coffee on the intestines of rats were studied separately. Scientists noted that after drinking coffee, contractions of muscle tissue in the lower parts of the large intestine, which is responsible for excreting fecal matter, were activated. In laboratory conditions, with the direct effect of the drink on tissue, the same picture was recorded, and with the same result when using caffeine and decaffeine solutions.

The results of the study made scientists think about the need to study the properties of coffee for the treatment of constipation. In particular, coffee-based preparations may be useful for patients with postoperative constipation or for the non-surgical treatment of intestinal obstruction. In addition, scientists have to establish which chemical compound contained in coffee has a beneficial effect on intestinal muscle tissue.

Beneficial features

Based on the results of numerous studies, it became clear that the benefits of a coffee drink with added milk are much higher than regular coffee. This is because the elements contained in these two ingredients do not react chemically with each other. Therefore, the more milk in a drink, the less caffeine it contains. Milk, in turn, helps replenish calcium, which is washed out of the body. In addition, this drink has a low calorie content and has a diuretic effect, so nutritionists recommend drinking it in small quantities.

This drink has a number of advantages:

1. Contains many vitamins, minerals, antioxidants, which have a positive effect on the epidermis, slow down the aging process of the body, help strengthen cells, and prevent hair loss.
2. Natural ground coffee has an effect on the nervous system, stimulating its activity. Consuming it in small quantities helps increase brain activity, reduces feelings of fatigue and drowsiness, and provides increased physical and mental activity.
3. The composition of the drink ensures healthy, restful sleep, so one cup of it in the evening will not cause insomnia.
4. Adding milk to coffee prevents the development of malignant tumors and also washes calcium out of the body.
5. The antioxidants contained in the drink help prevent the development of many diseases, including hypotension.

Harm of coffee with milk

Coffee contains caffeine, which is a drug. In small quantities it is beneficial to the body, but in large quantities it can harm it. Therefore, doctors recommend adding milk to the drink and drinking up to four small cups a day. Otherwise, this can lead to the development of stress and disruption of body functions.

The coffee drink also has some negative qualities:

1. The milk included in the drink can cause allergic reactions in some people and provoke diarrhea.
2. Caffeine helps flush out not only calcium from the body, but also sodium, magnesium, and potassium. Milk only replenishes the loss of calcium; all other components are lost forever.
3. Some people use decaf instant coffee. But they do not know that dichloromethane is used to extract caffeine, which has a negative effect on the respiratory system.

In addition, drinking coffee with milk is contraindicated in the presence of the following diseases and conditions:

• pregnancy, as the risk of abnormalities in the development of the fetus increases, as well as the risk of miscarriage;
• lactation period;
• urolithiasis disease;
• diabetes mellitus type 2;
• diseases of the cardiovascular system, for example, hypertension, ischemia;
• Diseases of Parkinson's, Alzheimer's and others.

Conclusions - is this drink worth drinking?

In order for coffee with milk to benefit the body, it must be consumed in small portions several times a day. Bean coffee is much better for this than instant coffee. It is pre-fried and then ground at home, which allows you to preserve all the beneficial properties of the drink. The milk must be fresh, pre-boiled. By following all these recommendations, you can get a high-quality and healthy drink that has a pleasant taste.

Scientists claim that coffee granules and milk, when combined in one drink, do not interact, so it is not absorbed by the body so quickly, therefore, caffeine does not affect the nervous system so sharply.

digestion?

To get only positive effects and benefits for the digestive tract, remember these simple points of proper use, adjusting them to the characteristics of your health.

• Don't drink coffee on an empty stomach. The best option is 40-60 minutes after a meal, or at least with food, even a small sandwich, apple, cheese, cookies.
• The drink should be warm, not scalding hot (it will cause severe irritation of the mucous membranes and, possibly, abdominal pain), and not iced (ice coffee should be drunk separately, the cold stimulates the stomach to move undigested food further into the intestines).
• If the acidity is high, try dark roasted beans; if the acidity is low, try lighter roasted beans.
• If you often have heartburn, switch to filtered natural (forget about instant). Either let it sit thicker so it doesn’t get into your stomach, or buy filters at a coffee store. You can even use paper towels.

If drinking coffee causes pain or certain problems, be sure to consult your doctor and do not self-medicate.

We are looking for a replacement

A good alternative to coffee is drinks made from chicory or carob (powder from carob). Carob tastes similar to sweet coffee (carob contains natural sugars), but does not have the disadvantages of natural coffee. Coffee substitutes can be made from a mixture of carob powder and ground chicory root.

Relevance of the problem

In recent years, numerous studies have demonstrated a link between coffee consumption and a reduced risk of developing type 2 diabetes and certain types of cancer, as well as Parkinson's disease.

At the same time, accumulating evidence suggests that the composition of the gut microbiome is maintained by coffee consumption, thereby promoting or reducing the risk of disease.

“We still need to learn more about how bacteria and the body interact to influence our health.”

How does coffee affect various human organ systems?

You may have noticed that along with your increased performance after your morning espresso, you experience heartburn and a frequent urge to urinate. Have you ever thought that this could be due to caffeine? Let's figure it out.

The effect of coffee on the heart and blood vessels

Under the influence of caffeine, the heart rate increases. For a young, healthy heart, as well as elastic blood vessels, this effect is positive in moderate doses. But for people who are at risk of developing cardiovascular diseases, rapid heartbeat can cause complications: lack of oxygen in the heart muscle, hypertensive crisis. And for people with coronary heart disease, high doses of caffeine can serve as a trigger for arrhythmia and even heart attack.

Effects of coffee on the stomach

The effect of coffee on the stomach and gastrointestinal tract is associated not so much with caffeine, but with the acids contained in the drink. Their action is to stimulate the work of gastric secretions, which entails accelerating the digestion of food and activating the production of gastric juice. If there are no gastrointestinal pathologies, and coffee is not consumed in excess of the norm, then the drink will help improve digestion and stool. But for people with gastritis and stomach ulcers, these benefits from coffee can be harmful, so you should give it up and switch to herbal teas and cocoa.

Effects of coffee on the liver

There is ongoing debate about the effects of coffee on the liver. Some doctors say that the drink is healthy, others are inclined to believe that it is harmful. It is important to note that when drinking natural coffee, a person with a healthy liver will not be in any danger. But instant coffee is not recommended to anyone at all.

As for the benefits, we all know that the liver cleanses our body. And since caffeine promotes gastric secretion and improves metabolism, cleansing processes are accelerated. It should also be said that coffee beans contain components involved in lipid metabolism. This reduces the risk of fatty liver disease. The drink also helps prevent the formation of scar tissue, which promotes rapid organ regeneration.

It is better to consult your doctor about whether you should drink coffee if you have liver disease.

The effect of coffee on the brain and nervous system

Regular consumption of coffee improves cognitive abilities, reactions, logical thinking, reduces the effects of stress and the occurrence of depression. However, abuse and excess doses lead to depression, lethargy, and insomnia. Therefore, you can drink no more than 3 cups a day and no later than 14:00-15:00 hours.

Effect of coffee on kidneys

About 10% of caffeine is excreted unchanged from the body by the kidneys. With constant use, most people experience an increase in diuresis, which means that a person goes to the toilet more often. This entails increased fluid loss, disrupting the metabolic processes of electrolytes and minerals. At the same time, calcium and sodium are washed out of the body. Taken together, these processes can lead to the formation of kidney stones. Therefore, after each cup of coffee, it is recommended to drink a glass of clean water to replenish your water balance.

The effect of coffee on a woman’s body - can pregnant women drink the drink?

As for the effects of caffeine on the body of the expectant mother, it is worth saying that you should use the invigorating elixir with caution. The recommended dose for pregnant women is 1 cup. Exceeding doses can lead to insomnia, anemia, heartburn and even the threat of miscarriage. You can learn more about coffee during pregnancy from the article “Is coffee ok for pregnant women?”
