People really like coffee that hot

The myth of coffee: how many cups are healthy? That's what scientists say

English researchers have viewed a good 200 studies and compiled the effects of coffee on our organism. What are the health benefits of coffee and what to consider.

Coffee studies are now like beans in a pack - they usually provide new insights into the positive effects of this stimulant. Certainly, in many of these studies, the donors come from those branches of the economy that do good business with the brown bean trade.

But there are also studies that have been independently financed by the industry. In December 2017, English researchers published the results of 201 such overview studies in the renowned "British Medical Journal".

Coffee lowers the risk of cancer

Coffee consumption is much more likely to be associated with health benefits than it is with harm. The greatest positive effect is achieved by people who drink three to four cups of coffee a day compared to those who do not drink any coffee at all. Coffee drinkers were able to reduce their risk of certain diseases the most significantly.

This also has an impact on the risk of cancer: the probability of heavy 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.

A higher coffee consumption is also associated with a lower risk of Parkinson's, Alzheimer's and depression. The liver and metabolism also benefit: for example, the risk of liver cirrhosis is significantly lower. Coffee drinkers are also less likely to develop type 2 diabetes.

Coffee: 19 positive effects on health

There were a total of 19 positive effects on health. In contrast, there were only six negative effects. Above all, the risk of cardiovascular diseases, such as heart attacks and strokes, is reduced by drinking coffee.

And what's even more surprising, according to the results, coffee has no effect on people with high blood pressure. They can therefore drink coffee without hesitation. In general, coffee consumption does not seem to affect blood pressure. For a long time this was propagated differently.

Not everyone can take coffee

But not everyone can tolerate coffee, among other things 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. A 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 do not tolerate coffee well, for example because they have a racing heart or stomach pain, should of course not listen to studies, but should rather go without their body and coffee.

What makes coffee so healthy?

According to the UK study, "Roasted coffee is a complex blend of over 1,000 bioactive compounds with potential 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 - for example from caffeic acid.

But every 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 large intestine.

What happens if you drink more than three to four cups?

According to the authors of the study, not much happens with more coffee: "An increase in consumption to more than three cups a day was not associated with harm, but the beneficial effect was less pronounced."

In this respect, three to four cups actually seem to be the ideal daily ration for most people.
