Coffee has long been considered a familiar "friend" that helps keep people alert and increases their ability to concentrate. Many studies have also shown that moderate coffee consumption can support the liver, reduce the risk of cirrhosis and improve kidney function. However, the habit of drinking coffee incorrectly causes serious harm to the body, especially the liver and kidneys.
One of the most popular forms of drinking is drinking coffee that is too thick and too many times a day. High caffeine content causes a strong stimulation of the nervous system, while forcing the liver to increase metabolism. In the long run, the liver is overloaded, easily leading to metabolic hepatitis. The kidneys are also affected because they have to filter large amounts of caffeine and additives, which can increase the risk of kidney stones or impaired function.
In addition, the habit of adding too much sugar, condensed milk or syrup to coffee also increases the burden on the liver. Excess sugar can easily accumulate into fat, causing fatty liver, while the kidneys have to work harder to balance blood sugar and eliminate excess matter.
Coffee in itself is not dangerous, its the way we drink it, says Dr. Samantha Heller, a clinical nutritionist at New York University. When consuming more than 45 cups per day or added more sugar and cream, the body is under great pressure, especially the liver and kidneys".
Another worrying habit is drinking coffee instead of water. Caffeine has diuretic properties, causing the body to lose water quickly. When not supplemented with enough water, the kidneys are vulnerable and form stones.
Experts recommend: healthy adults should only drink 12 cups of coffee per day, avoid drinking too late to avoid affecting sleep, and especially should not use coffee instead of water. In addition, you should limit added sugar and ice cream to reduce the burden on the liver.
Whether coffee is beneficial or harmful depends entirely on consumption habits. A cup of coffee properly will bring alertness and support health; on the contrary, abusing and drinking incorrectly is a double-edged sword that destroys the liver and kidneys.
