Positive and negative effects of coffee consumption
How much coffee consumption is healthy and from what amount should you avoid the next espresso? For a long time, the views on this question were extremely different. Sometimes less isn't more - at least when it comes to coffee. The following seems to apply here: it can be a little more. Scientists have now found that a healthy body can take a lot of caffeine. Four to five cups of espresso a day are therefore not a problem for our health.

Do you like to drink a lot of coffee a day? Have you been told for years that so much coffee is not good for your health? If so, stop worrying. Such high coffee consumption is not unhealthy, it could even promote your health. Doctors found that healthy people can easily consume four to five cups of espresso every day.

The truth about the effects of coffee on the human body
If you are a coffee drinker, you are sure to know its benefits. Even the scent of the hot drink triggers a feeling of relaxation and security in many people. There are numerous people who can hardly get out of bed in the morning without the “wake-up”. For those affected, morning coffee is simply part of normal life. However, coffee had a reputation for years that it would make you sick. Excessive coffee consumption has been said to trigger nervousness, restlessness and sleep problems. But what about the stimulating hot drink? The following article tries to clarify open questions about the consumption of coffee.

How much coffee should you drink?
In general, coffee only poses a risk to our health if it is consumed in large quantities on a regular basis. This is due to the high caffeine content in the hot beverage, explains Hans Hauner, director of the Else Kröner-Fresenius Center for Nutritional Medicine (EKFZ) at the Technical University of Munich to the news portal “Spiegel online”. If you consume up to 400 milligrams of caffeine throughout a day, you don't have to worry about your health. Because such a small amount of caffeine is considered safe. An adult could therefore drink four to five cups of espresso or even up to eight cups of black tea a day, quotes the news portal Gabriele Graf from the NRW consumer center in Düsseldorf. For your information: A normal cup with a content of 200 milliliters of filter coffee contains around 90 milligrams of caffeine.

Are there any groups of people who should be careful about consuming coffee?
Not all people can drink that much coffee. Experts warn that pregnant and lactating women should be careful when consuming coffee. In this group, the caffeine passed freely through the placenta. Thus, it gets into the unborn child's cycle during pregnancy, explains Gabriele Graf. The big problem is that the liver of the unborn child cannot break down the caffeine so quickly. Therefore, pregnant and breastfeeding women are advised to be careful with their consumption and to enjoy very little coffee during pregnancy, the nutritionist adds.

How quickly can coffee take effect?
If people immediately feel more awake after a sip of coffee, this cannot really be possible. Such people are subject to a so-called placebo effect. The stimulant effect does not begin until about 15 to 30 minutes after drinking the “wake-up”, Margret Morlo is quoted by the association for nutrition and dietetics from “Spiegel Online”. How long does it take for the caffeine to spread throughout the body through the human bloodstream.

How long does it take for caffeine to break down in our body?
It can take hours for the body to break down all of the caffeine. A guideline is: In healthy adult people, the average half-life in the body is about four hours. The body then excreted about 50 percent of the caffeine ingested, says Margret Morlo.

What time should we have our last cup of coffee?
Views differ on this, because there is no real rule of thumb for this question. It depends on the individual person. Some people can still drink cola, coffee or black tea in the evening and still enjoy a good night's sleep. In others, excessive or late coffee consumption can cause real sleep problems. So everyone has to find out for themselves at what times of the day they best tolerate caffeine, explains Hans Hauner.

Are there any other side effects of coffee that should be considered?
Coffee stimulates the human circulation, which makes our heart beat more often, says Hauner. The pulse and our blood pressure then start to rise. But don't worry, this process is not really dangerous for healthy people. Even with increased coffee consumption, the risk of developing atherosclerosis or suffering from a heart attack does not increase, adds Hauner. High blood pressure patients can also enjoy coffee, albeit in moderate amounts. The consumption of coffee does not raise blood pressure significantly and is dangerous to health, even if a widespread assumption is different. However, you should be careful if you suffer from so-called rhythm disorders. It is better to consult your doctor before you start consuming coffee unchecked. If you really drink far too much (liters) of coffee, you also risk developing anxiety symptoms, hyperactivity and gastrointestinal complaints, the expert adds.

Withdrawal symptoms from coffee?
It is actually possible that withdrawal symptoms may result from coffee consumption. The body gets used to regular consumption and the effects of the caffeine it contains. If the rations of caffeine fail to appear, our experts can respond by developing headaches and difficulty concentrating. This so-called caffeine withdrawal headache mostly affects people on weekends when people try to take a coffee break. Nevertheless, coffee is by no means an addictive substance.

Positive effects of coffee on human health?
Many people are likely to experience one of the main effects of coffee every day. The caffeine contained reduces our fatigue and slows down the triggering body's own messenger substance adenosine, explain the doctors. This improves concentration and so-called depths of performance can be overcome. But there are other positive effects of coffee. A cup of coffee, for example, can help diabetes patients to have a beneficial effect on insulin effects. This is due to the chlorogenic acid contained in coffee, explains Hauner. There are other studies that indicate that coffee drinkers have a longer life expectancy and are less likely to develop colon cancer. However, these studies have not been able to prove correctly that coffee consumption is the cause of these positive effects and what exactly triggers them. Scientists are still trying to decipher which of the many substances in coffee are responsible for these effects.

Coffee does not remove any liquid from the body
For a long time it was said that coffee does not add any liquid to our body or even withdraw it from the body. But coffee can be added to the so-called liquid balance as normal. This says that every person should drink about two liters of liquid a day. Nevertheless, it should be noted that coffee is not a suitable thirst quencher because it contains a lot of caffeine and this affects our heart and circulation through its stimulant effect. (as)
