Drinking coffee regularly helps prevent type 2 diabetes, liver and heart disease. And as if this wasn't enough to convince the undecided about the goodness and healthy power of a nice cup of coffee, from today we know that coffee also protects the kidneys! This emerges from a very recent scientific research published in Kidney International Reports by an American team from the prestigious Johns Hopkins University School of Medicine, Baltimore (Tommerdahl et al, Kidney International Reports, May, 2022).
The benefits of coffee, what previous research says
Coffee is one of the most loved and consumed drinks in the world. It is also one of the healthiest, since coffee, thanks to caffeine and antioxidants such as chlorogenic acid and diterpenes, helps prevent chronic and degenerative diseases. For example, regular coffee drinkers have a lower risk of developing diabetes but also cardiovascular problems, fatty liver, cirrhosis and neurodegeneration. Not only that, previous studies have also been able to show that regular coffee consumption is able to reduce the risk of chronic kidney diseases. Today, thanks to the study just published, we know that coffee can also reduce the risk of acute kidney injury. In acute kidney injury, the kidneys stop performing their function very quickly, this can happen within a few hours or days. The causes are due to heart or liver disease, severe dehydration, incorrect intake of some drugs such as antihypertensive drugs, but also inflammation. In a short time the body is invaded by waste substances, swelling of the legs and ankles may occur, but also mental confusion, numbness, drowsiness and difficulty in breathing.
Coffee protects the kidneys, here's the study
Scientists analyzed the data of 14207 adults, average age 54, recruited between 1987 and 1989 by a large study, the Atherosclerosis Risk in Communities Study, which is all now underway with the aim of studying cardiovascular diseases and their etiology. Over the years, the volunteers have been followed to assess their state of health and their eating habits, including the consumption of coffee. Well, it emerged that those who consume at least one cup of coffee a day have a 15% reduction in the risk of developing acute kidney injury compared to those who do not drink coffee. The greatest benefits are observed for those who drink 2 to 3 cups a day with a risk reduction of up to 23%. Researchers argue that this protective effect is due to the presence of caffeine, which improves the use of oxygen by the kidney tissues. In fact, for good kidney function it is important that the oxygen supply is stable.
Here we have further proof that coffee is not only a pleasant moment of the day, but also a healthy one. In any case, the important thing is not to exceed the quantities as the greatest benefits have been observed by drinking a maximum of three cups of coffee a day.
