More than four cups a day – Why coffee protects the liver
Coffee is not only a stimulant, but also a liver protector : This news should be particularly interesting for the many coffee lovers in Germany. According to a study by the German Institute of Human Nutrition (DIfE) in Potsdam-Rehbrücke, regular coffee consumption could significantly reduce the risk of developing liver cancer. In this article, we would like to take a closer look at how exactly this works and what research says about it.Coffee – the Germans’ favorite drink
Whether espresso, cappuccino or classic filter coffee - in Germany, coffee is appreciated and consumed in all its variations. Over 80 percent of adults drink an impressive 162 liters of coffee every year. It's not just about the taste and the invigorating effect, but also about the ritual and the moment of pleasure that a cup of coffee offers. But the popular drink apparently has more to offer than many of us previously suspected.Coffee and the liver – a special relationship
Scientists have long suspected that coffee could have a positive effect not only on the heart and circulation, but also on the liver. Now a comprehensive study by researchers at the German Institute of Human Nutrition Potsdam-Rehbrücke has further confirmed this assumption. Using data from the EPIC study (European Prospective Investigation into Cancer and Nutrition), the connection between regular coffee consumption and a reduced risk of developing liver cancer was investigated.What is the EPIC study?
The EPIC study is one of the largest long-term studies in the world that examines the links between diet, cancer and other chronic diseases. In this study, more than 519,000 participants from ten European countries were observed over many years. For Germany, the German Cancer Research Center (DKFZ) in Heidelberg and the DIfE are involved in the EPIC study. The Potsdam EPIC sub-study alone includes more than 27,500 adult participants. What makes the EPIC study so special is its prospective nature. Participants were healthy at the start of the study, making it possible to identify risk factors for certain diseases before they even break out. This prevents data distortion, which is often a problem in retrospective studies.Coffee consumption reduces the risk of liver cancer
The results of the study are impressive: people who drink more than 600 milliliters of coffee a day - the equivalent of about four cups - have a 75 percent reduced risk of developing liver cancer compared to those who consume less than 300 milliliters a day. This is an astonishing figure that should reassure many coffee lovers. The researchers also analyzed the influence of 21 liver-relevant biomarkers in the participants' blood and were able to identify three of them that play an important role in the connection between coffee consumption and liver cancer. These are interleukin-6, a messenger substance that is involved in the regulation of inflammatory reactions, and the enzymes aspartate aminotransferase and gamma-glutamyltransferase, which indicate damage to liver cells and bile diseases.The Science Behind Coffee Enjoyment
How exactly does coffee protect the liver? The results of the study suggest that there is a causal relationship between heavy coffee consumption and a reduced risk of liver cancer. Coffee appears to protect the liver from inflammation and cell damage, which in turn prevents the development of cancer. Krasimira Aleksandrova, one of the study's lead scientists, explains: "Our biomarker analyses suggest that there is a causal relationship between heavy coffee consumption and a reduced risk of liver cancer. Coffee protects the liver from inflammation and cell damage and thus counteracts the development of cancer."Should we now drink more coffee?
Anyone who thinks that they now have to drink more coffee to protect their liver is wrong. As Heiner Boeing, head of the Epidemiology Department at the DIfE, emphasizes, coffee consumption is not associated with an increased risk of chronic diseases, but people should not feel obliged to consume coffee in large quantities. "Drinking coffee should be a pleasure and not a chore," says Boeing. Preventing diseases depends on the entire lifestyle and not just on high coffee consumption.How does coffee affect health?
There are numerous studies that look at the health effects of coffee. In addition to the current EPIC study, there is evidence that coffee can reduce the risk of type 2 diabetes, cardiovascular disease and even certain neurological diseases. The positive effects of coffee are often attributed to the multitude of antioxidants and bioactive compounds in coffee, which can have an anti-inflammatory and protective effect on cells.Conclusion: Luxury food with potential
Coffee is more than just a luxury item - it has the potential to protect the liver and possibly other organs. But as with many things in life, the dose makes the poison. If you like coffee and can tolerate it well, you can enjoy it in moderation without having to worry about your health. But coffee alone is not a miracle cure. A healthy and balanced lifestyle remains the be-all and end-all for good health.What can we learn from research?
The results of the EPIC study are further evidence that our diet and lifestyle have a major impact on our health. It is fascinating to see how an everyday luxury item like coffee can have such positive effects on our liver. But ultimately, it is the sum of all our daily decisions - from diet to exercise to relaxation and sleep - that determines how healthy we stay. Share your experiences! Do you drink coffee regularly?
