A new study from Italy offers encouraging news for coffee lovers concerned about their liver health. Researchers examining over 1,000 regular coffee drinkers found that daily consumption of espresso and moka pot brewed coffee was associated with significantly lower odds of developing metabolic dysfunction-associated steatotic liver disease, commonly called MASLD.

What the Study Found

Published in March 2025 in Frontiers in Nutrition, this research tracked 1,079 coffee-drinking adults in southern Italy to explore connections between their daily Italian-style coffee habits and MASLD risk. The results showed a clear protective pattern: people who drank one cup daily had roughly 52% lower odds of developing the disease compared to those drinking less than one cup. The benefit increased with each cup, reaching 59% lower odds at 4 to 6 cups per day, then plateaued.

MASLD develops when fat accumulates in the liver alongside at least one cardiometabolic risk factor such as obesity, elevated blood sugar, high blood pressure, or abnormal cholesterol levels. The condition excludes cases driven primarily by excessive alcohol consumption.

Why Espresso and Moka Pot Matter

The study specifically examined espresso and moka pot brewing methods, which dominate Italian coffee culture. These pressure-based extraction techniques differ fundamentally from filtered or instant coffee because they retain higher concentrations of beneficial compounds. Unlike paper-filtered coffee, both methods preserve fat-soluble elements and antioxidants that may provide protective effects.

Researchers identified two key compounds responsible for these benefits: diterpenes and chlorogenic acids. Prior research has linked these substances to antioxidant, anti-inflammatory, and lipid-regulating properties, all of which directly address the mechanisms underlying MASLD. The authors noted that Italian-style coffee’s unique composition may explain why these brewing methods showed stronger associations with liver protection compared to other techniques.

Broader Context: What Scientists Already Know

This Italian study joins a growing collection of research linking coffee consumption to improved liver outcomes. A recent literature review from December 2025 found that coffee drinkers across studies showed lower risks of liver disease overall and slower progression of fibrosis, cirrhosis, and liver cancer. A 2021 UK Biobank study discovered that coffee drinkers had 21% lower risk of chronic liver disease and 49% lower risk of death from chronic liver disease compared to non-drinkers.

What distinguishes the new Italian research is its focus on specific brewing methods and dose amounts within a single, culturally uniform population. By controlling for variables like age, sex, body weight, blood pressure, diet quality, smoking status, and cholesterol levels, the authors strengthened their ability to isolate the coffee effect.

What This Means for Shoppers

If you enjoy coffee and are concerned about liver health, these findings suggest that espresso and moka pot preparations may offer advantages beyond simple enjoyment. The research indicates that 4 to 6 cups daily provided the maximum protective effect, though benefits appeared at lower consumption levels too.

However, the authors advised caution for certain populations and acknowledged limitations in their study design, including its observational nature and reliance on self-reported dietary information. The findings represent association rather than proof of causation. Before making significant dietary changes, especially if you have existing liver conditions, consult your healthcare provider.

The Bottom Line

This Italian research adds meaningful evidence to the case that coffee consumption supports liver health through specific biological mechanisms. The focus on brewing method reminds consumers that how you prepare your coffee may matter as much as the coffee itself. For people seeking natural dietary approaches to disease prevention, incorporating espresso or moka pot coffee into a balanced routine may offer genuine benefits worth considering. As always, moderation and individual health circumstances should guide personal choices.
