Coffee for the liver: a mechanistic approach

Area of Science:

• Hepatology
• Nutritional Science
• Gastroenterology

Background:

• The liver is vital for metabolism and detoxification but susceptible to damage from viruses, alcohol, and poor diet.
• Coffee is a globally popular beverage with recognized health benefits.
• Research indicates coffee consumption may protect against liver diseases.

Purpose of the Study:

• To review the impact of coffee consumption on liver health.
• To explore epidemiological, mechanistic, and clinical evidence supporting coffee's hepatoprotective effects.
• To discuss implications for liver disease prevention and management.

Main Methods:

• This is a narrative review, synthesizing existing epidemiological, experimental, and clinical studies.
• Analysis of the bioactive compounds in coffee and their proposed mechanisms of action.
• Examination of studies on coffee's effects on liver enzymes, disease progression, and mortality.

Main Results:

• Epidemiological data suggest coffee reduces the risk and progression of liver diseases, including fibrosis, cirrhosis, and hepatocellular carcinoma.
• Bioactive compounds in coffee (caffeine, polyphenols, diterpenes) exhibit anti-inflammatory, antioxidant, antifibrotic, and anticancer properties.
• Coffee consumption is linked to lower liver enzyme levels, reduced liver damage, and decreased liver disease mortality.

Conclusions:

• Coffee consumption demonstrates significant hepatoprotective effects, mitigating liver damage and disease progression.
• Mechanisms include modulating inflammation, oxidative stress, fibrosis, lipid metabolism, and gut microbiota.
• Coffee offers potential benefits for the prevention, treatment, and management of various liver conditions.
