Contrary to popular belief, black coffee has a protective effect on the liver, provided you drink the right amount.
Too stimulating, bitter, “harmful to the heart”… Coffee often has a bad reputation. However, this drink that we nickname “the little black” has a nutritional richness particularly interesting for the liver. As long as you drink the right amount and in the right way.
The 3 benefits of coffee on the liver
► Its antioxidants delay liver aging. Thanks to its richness in antioxidants, caffeine has a protective effect for the liver. “Antioxidants contained in coffee (polyphenols) have several benefits for the liver: they allow delay the aging of liver cells and of clean them of greasethus reducing inflammation and liver damage, which can be responsible for steatosis or hepatitis” explains Professor Patrick Marcellin, hepatologist at Beaujon hospital.
► Caffeine limits the risk of cirrhosis. Caffeine would limit the appearance of scars in the liver called hepatic fibrosis, the final stage of which is cirrhosis. A study published in the journal Hepatology showed that drinking 3 coffees per day slows the progression of liver damage. In 2015, a meta-analysis of 16 studies published in PLOS One reported that people who consumed two or more cups per day had 47% reduced risk of developing liver cirrhosis.
► Magnesium protects the liver from NASH. Coffee contains magnesium (an espresso contains around 80mg of magnesium), a mineral that has a protective effect on the liver. And according to several scientific studies, including one published in the Public Health Nutritiona diet rich in magnesium would reduce by 30% THE risk to suffer from non-alcoholic fatty liver disease (NASH or fatty liver), the most common liver disease in the world.

However, recent studies have shown that caffeine stimulated the functioning of liver cells and improve liver health in patients with liver disease, such as NASH For example, wants to restore the hepatologist. Another meta-analysis (18 studies, 2.3 million participants) published in the BMJ Journals pointed the protective effect of coffee in people who already had liver problems at the start (cirrhosis), which suggests that coffee is indeed capable of slowing the progression of inflammatory lesions and thus reducing the risk of liver cancer.
