Coffee has long been part of daily routines around the world – not only because it gives an energy boost. Coffee contains hundreds of compounds that may protect against liver disease and a range of other health conditions, with three or four cups daily being linked with reduced risks of chronic liver disease, fatty liver disease and liver cancer, according to new research conducted at UK Biobank data from over half a million individuals over 10 years. Researchers discovered that those who consumed moderate quantities of ground or instant coffee (whether caffeinated or decaffeinated) were less likely to develop liver diseases associated with liver cancer or chronic liver disease compared with those who consumed minimal quantities whereas ground coffee was more beneficial in protecting against chronic liver diseases as was ground coffee slightly more beneficial in terms of protection than instant.

Studies have demonstrated that regular coffee drinking can significantly lower liver enzymes, decrease hospitalizations and mortality for those suffering from both alcoholic hepatitis and non-alcoholic steatohepatitis (NASH), yet its exact mechanisms remain unknown. One theory suggests that coffee contains chemicals called polyphenols and carotenoids which may prevent fat accumulation in the liver while decreasing progression of fibrosis.

Cafestol has also been shown to slow cell growth and increase cell death in hepatocellular carcinoma cells, providing another potential protective measure against liver damage and inflammation. Coffee may also help mitigate oxidative stress that increases inflammation and causes further liver damage.

However, before making any adjustments to your coffee consumption habits, several important considerations must be made. An excessive coffee intake can lead to headaches, irritability and insomnia in certain individuals; in those with heart conditions it could increase blood pressure significantly and increase their risk of stroke or heart attack; those living with Hepatitis C or liver diseases should avoid excessive coffee as it could worsen symptoms while delaying treatment progress.

If you’re thinking about changing your coffee habits, it’s worth remembering that its health benefits apply equally to all varieties – ground or instant, caffeinated or not – provided no additional sugar or cream are added. Furthermore, research has demonstrated that black and green tea without milk are better options for liver health.
