Coffee and its effects on health

Coffee is the most popular hot drink – especially in Germany. It has been known for generations that it is indispensable for many occasions, and for some, it is the only way to start the day well. For a long time now, there have been repeated discussions about how healthy or unhealthy coffee really is when it comes to enjoying coffee. It is often said that coffee is said to increase blood pressure and prevent some people from falling asleep easily. On the other hand, it should also reduce the risk of diabetes and make the blood vessels elastic. But what should we really think of coffee? Coffee and its health effects – article overview:

Coffee and its effects on health
  • Caffeine – a companion in every situation
  • What is generally accepted as proven
  • Germs and bacteria in the fully automatic coffee machine?
  • Caffeine can affect everyone differently

A companion in every situation

Coffee can go with you all day. In the morning he helps to wake up, at lunchtime he supports digestion, in the afternoon he is often the companion on appointments, and coffee is always a part of meetings. In Germany around 2014, every German citizen is said to have drunk an average of 162 liters of coffee.

With an average cup size of 150 milliliters, this means over 1,000 cups of coffee per person. A roasted coffee bean contains more than 800 aromatic substances. It only contains about two kilocalories per 100 milliliters, which does not make the hot drink unpopular even in diets. And coffee wakes you up. You shouldn’t be surprised that so many people love coffee.

Whether this pleasure is mainly positive or whether the Germans are not just indulging in a vice needs to be clarified. Because coffee is also considered unhealthy, it is said to make some nervous, cause palpitations and, according to some rumors, even shorten life !?

The fact that coffee drinkers actually live shorter lives is considered out of date. Because in some studies, it was forgotten that coffee drinkers are often also smokers. Coffee seemed to cause health problems, although the poor state of health was actually more due to smoking.

Today, the results of numerous studies are said to indicate that coffee is associated with a lower overall mortality rate. But even with these studies, one must look closely and critically examine whether they are not being financed in any way from the coffee lobby’s direction.

What is generally accepted as proven

You will likely find as many studies that attest to the drink to negative effects as those that show positive effects. Some points are still controversial among scientists and others are now considered either well-proven or refuted.

What should be undisputed is that caffeine (one of the most famous ingredients in coffee) wakes you up. The caffeine binds to certain molecules on cells. These are the so-called adenosine receptors. This substance displaces the body’s own messenger substance adenosine, which causes tiredness. So coffee unfolds its stimulating effect. It is also known that caffeine accelerates the heart’s activity, triggers the urge to urinate, dilates the bronchi slightly, and can promote concentration.

There are also people who react to coffee/caffeine with sweating. You can tremble and be nervous as well. This often happens after consuming large amounts of caffeine. The ingredient only becomes really dangerous and sometimes life-threatening only in larger quantities. A lethal dose of caffeine for otherwise healthy people is several grams.

Germs and bacteria in the fully automatic coffee machine?

In all the discussions about whether or not healthy, it is often forgotten that it is not the coffee, with its naturally given ingredients, that can be unhealthy, but the way it is prepared. What is meant is that it is, for example, germs that get into the coffee. The fully automatic coffee machine can be to blame here. Anyone who owns such a device and ignores its cleanliness can quickly find fungus and bacteria in their beloved hot drink.

A fully automatic coffee machine is something beautiful. You can get different coffee specialties simply at the push of a button, freshly ground and brewed. But you should also deal with the machine so that uninvited and unhealthy guests can be avoided. Because unfortunately, they find plenty of food in the devices. This can be layers of slime in the water tank, mold, and fungus in the waste container, or bacteria that have spread to the brewing group. In order not to let things get that far, the coffee machine should be serviced and cleaned regularly. You can find more on the subject of health issues in relation to fully automatic coffee machines, for example, under the link above.

Caffeine can affect everyone differently

The fact that caffeine affects everyone differently is how quickly the caffeine is broken down in the respective body. So it varies greatly from person to person and is also influenced by genes, among other things. Half of it is metabolized with one of them after four hours, and with the other, up to 50 percent of the caffeine absorbed can still be found in the organism after eight hours. It is also interesting that the substance is supposed to work for twice as long as men in women. And again, children, young adults, and pregnant women react differently than older people. It has also been shown that the concentration of caffeine in the body in smokers tends to decrease faster than in non-smokers.

Also, medication can affect how long it works. Besides, in a 2008 study at the university, researchers found that caffeine works faster in men than in women. In any case, with regular coffee consumption, the body gets used to the active ingredient and reacts less strongly to the caffeine than with someone who rarely consumes caffeinated beverages.
