Tomar café empeora la salud del riñón

Definitively, coffee hinders the process of filtration of the blood carried out by the kidney. and this can be especially detrimental in those with fragile kidney health.

This has been shown by a study carried out by researchers from the ciberobn and the rovira i virgili university, which suggests that the consumption of caffeinated beverages, whether coffee or tea, is related to a greater deterioration of kidney function .

diet influences the kidney

Chronic kidney disease affects 10% of the world’s adult population and more than 20% of those over 60 years of age. it is influenced by many factors and greatly deteriorates the quality of life of the patient, especially if they are older people with obesity.

That is why it is so important to establish preventive strategies that help to stop the deterioration of the kidney. and one of them is, without a doubt, taking care of your diet.

many dietary components played key roles in kidney function and preventing or slowing disease progression.

Based on this, the researchers from the ciberobn and the rovira i virgili university will determine to explore the possible association between the consumption of coffee and tea and the changes that would occur in a year in glomerular filtration rate, which is an important marker of kidney function.

To do this, it carried out a study in collaboration with 23 other Spanish research centers and with the participation of 5,851 elderly people who were overweight or obese.

coffee and tea are not good for the kidney

The study shows that what may be good for general health may not not be good for the kidney.

This is the case of coffee and tea, two beverages that contain caffeine and are widely consumed throughout the world.

Coffee seeds are characterized by their high content of polyphenols (substances with antioxidant properties), caffeine, vitamins, minerals and bioactive phytochemicals with potential effects health benefits.

drinking more than 2 cups of coffee a day can affect kidney filtration

The epidemiological studies carried out so far on caffeine and kidney function have not revealed consistent results, that is, they have not shown a positive but not a negative effect on the kidneys.

However, the study by the cyberobn team led by jordi salas and andrés diaz within the framework of the predimed-plus project has found a link and not good.

the authors found that consumption of caffeinated coffee and tea, but not decaffeinated coffee, was associated with a decreased glomerular filtration rate after one year of tracking.

It was found that people who drank more than 2 cups of caffeinated coffee per day (approximately 50 ml per cup) had a greater deterioration of the glomerular filtration rate than those who drank less than one cup a day or than non-coffee or tea drinkers.
In addition, consumption of more than 2 cups of caffeinated coffee per day is associated with a 19% increased risk of faster kidney function loss .

“tea and coffee are rich in bioactive compounds with antioxidant and anti-inflammatory properties with possible improved effects on health”, says jordi salas.

However, “there are potential side effects of caffeine that, even in moderate doses, can worsen cardiovascular health in people with chronic kidney disease,” he concludes.

better decaf

Coffee is one of the most consumed beverages and the main source of caffeine in the Mediterranean diet.

It is true that, as we said, it has healthy properties, but according to the results of this study it is harmful to the kidney.

That is why researchers advise elderly people with obesity and cardiovascular risk to reduce their consumption or, even better, substitute it for decaffeinated to preserve the kidney health.

It should be noted that this study is observational and its results must be confirmed with a clinical trial. but if it has just been confirmed, advice on coffee and tea consumption should be included in nutritional strategies to prevent kidney disease in the same way that it is recommended to reduce carbohydrates in diabetes.
