Coffee consumption has many effects on our organism. (Source: t-online. English researchers have reviewed more than 200 studies. The effects of coffee on our organism summarized. What are the health benefits of coffee. What you need to know.
Coffee studies are now as plentiful as beans in a packet – they usually provide new insights into the positive effects of this stimulant. In many of these studies, the sponsors certainly come from the industries that do good business with the brown bean trade.
But there are also studies that were independently financed by the industry. In the prestigious British Medical Journal English researchers published the results of 201 such overview studies in December 2017.
Coffee has these positive effects
Coffee lowers the risk of cancer
Coffee consumption is much more often associated with health benefits than with harm. The greatest positive effect is achieved by people who drink three to four cups of coffee a day, compared to those who drink no coffee at all. Coffee drinkers were able to reduce their risk of certain diseases most significantly.
This also has an influence on the risk of cancer: the probability of frequent drinkers developing cancer is 18 percent lower than that of infrequent drinkers. This applies to certain types of cancer, including prostate cancer, leukemia and liver cancer.

Higher coffee consumption is also associated with a lower risk of Parkinson's disease, Alzheimer's disease and depression. Liver and metabolism also benefit: For example, the risk of cirrhosis of the liver is significantly lower. Coffee drinkers also develop type 2 diabetes less frequently.

In total, there were 19 positive effects on health . In contrast, there were only six negative effects. Above all, the risk of cardiovascular diseases, for example heart attacks and strokes, is reduced by coffee consumption.
And what is even more surprising: according to the results, coffee has no effect on people with high blood prere . These can therefore drink coffee without hesitation. At all, coffee consumption does not seem to affect blood prere. This was propagated differently for a long time.
Not everyone tolerates coffee
But not everyone can tolerate coffee, in part because of the caffeine it contains. This includes pregnant women, because the caffeine crosses the placenta. However, the fetus is not yet able to break down this substance. If they drink more coffee, their children usually have a lower birth weight. One cup of coffee a day is considered safe for pregnant women. If you want to be on the safe side, you should drink decaffeinated coffee.
Anyone who subjectively notices that they don't tolerate coffee well, for example because they get palpitations or stomach pains, should of course not listen to studies, but rather do without coffee and listen to their body.
What makes coffee so healthy?
The British study states: "Roasted coffee is a complex mixture of over 1.000 bioactive compounds with potentially therapeutic, antioxidant, anti-inflammatory and anti-cancer effects." According to the study authors, the most important active ingredients include caffeine as well as other natural chemical compounds – such as those derived from caffeic acid.
However, each person processes the substances differently. This is genetically determined and also depends on the individual intestinal flora, i.e. the composition of the bacteria in the colon.
