Good news for coffee lovers – your morning cup of black coffee may be doing far more than just helping you wake up and stay focused through the day. According to experts, plain black coffee, without added sugar, syrups, or creamers, contains compounds that can significantly benefit liver health and may even help protect against chronic liver disease. From reducing inflammation to lowering the risk of fatty liver disease, this everyday beverage could be supporting your body in more ways than you realise.
Dr Saurabh Sethi, a California-based gastroenterologist and hepatologist trained at AIIMS, Harvard and Stanford Universities, regularly reviews multiple liver scans every day as part of his practice. The doctor has shared why he makes it a point to drink coffee every single morning, explaining that he does so to help protect and support his liver health. In an Instagram video shared on May 17, the gastroenterologist states, “I’ve read 10,000 liver scans. I drink coffee every single morning. Here is why.”
Protects liver
According to Dr Sethi, black coffee is one of the most liver-protective beverages known to humankind. He notes that people who drink coffee regularly tend to have a lower risk of developing liver cirrhosis and other liver-related complications. He explains, “Coffee is one of the most liver-protective drinks we know of. Regular coffee drinkers have up to 44 percent lower risk of liver cirrhosis – across multiple large studies.”
Reduces liver enzymes
Drinking coffee regularly can also improve liver enzyme levels in those at risk. Elevated levels in your blood are usually associated with liver stress, inflammation or damage, as live cells leak these enzymes into the bloodstream when injured. Dr Sethi highlights, “It reduces liver enzyme levels in people at risk. Regular coffee intake is associated with lower ALT and AST – the exact markers I watch on every lab panel.”
Prevents fatty liver disease
The gastroenterologist notes that non-alcoholic fatty liver disease is becoming increasingly common worldwide. However, he explains that regular coffee consumption may actively help combat fatty liver disease, with research showing some of the strongest evidence for its role in protecting the liver and potentially preventing the condition. He explains, “It actively fights fatty liver disease. NAFLD now affects one in three Americans – and coffee is one of the only drinks with consistent clinical evidence behind it.”
Reduces liver inflammation
Coffee contains powerful antioxidants that may help reduce inflammation in the liver. It is also rich in polyphenols, compounds that actively combat oxidative stress – one of the primary drivers behind chronic liver damage and disease progression. Dr Sethi explains, “It contains powerful antioxidants that reduce liver inflammation. Chlorogenic acid in coffee reduces oxidative stress – the primary mechanism driving chronic liver damage.”
How many cups should you drink in a day?
According to Dr Sethi, drinking two to three cups of coffee a day is considered the sweet spot for maximising its liver-protective benefits. He explains, “Two to three cups a day appears to be the sweet spot. A landmark meta-analysis of over 400,000 patients found two to three cups delivers maximum liver protection – not one, not six.”
Does decaf work the same?
The liver-protective benefits of coffee come primarily from its polyphenols rather than its caffeine content. As a result, even people who drink decaffeinated coffee may experience similar health benefits. Dr Sethi highlights, “It works whether it is caffeinated or decaf. The benefit comes from polyphenols, not caffeine – decaf drinkers showed similar liver enzyme improvements in head-to-head studies.”
