A recent study published in the European Journal of Preventive Cardiology adds to the growing body of evidence suggesting that moderate coffee consumption may have significant health benefits.

Conducted by researchers analyzing data from the UK Biobank, the study focused on the relationship between coffee intake and cardiovascular health outcomes, including mortality risk.

The cohort comprised 468,629 participants, all initially free from cardiovascular disease, with an average age of 56.2 years and 44.2% being male. Throughout the study, researchers meticulously gathered information on participants' coffee-drinking habits, including frequency and quantity, as well as lifestyle factors like smoking and physical activity levels. They also collected data on cardiovascular risk factors such as high blood pressure, diabetes, and cholesterol levels.

Participants were categorized into three groups based on their coffee consumption: non-coffee drinkers (0 cups/day), small to moderate consumers (0.5-3 cups/day), and large consumers (>3 cups/day). Additional subsets underwent Atherosclerosis Index (ASI) assessments (139,727 participants) and Cardiac Magnetic Resonance (CMR) imaging (30,650 participants) to evaluate arterial health and heart structure/function, respectively.

Analysis revealed that 22.1% of participants did not consume coffee, 58.5% consumed small to moderate amounts, and 19.5% consumed large amounts. Over an average follow-up of more than 11 years, varying rates of all-cause mortality and cardiovascular disease mortality were observed among the different coffee consumption groups.

After adjusting for age, gender, lifestyle, and cardiovascular risk factors, the study found that individuals who consumed small to moderate amounts of coffee daily experienced significantly reduced risks of all-cause mortality (12%), cardiovascular disease death (17%), and stroke (21%) compared to non-coffee drinkers.

Interestingly, no significant association was found between large coffee consumption and reduced mortality risk. Moreover, those who consumed small to moderate amounts exhibited a lower Atherosclerosis Index, indicating reduced risks of atherosclerosis and ischemic cardiovascular disease. Further analysis revealed that the type of coffee consumed also influenced mortality risk reduction, with low-causal coffee consumers showing lower risks regardless of consumption level.

Regular consumption of freshly ground coffee was notably associated with lower risks of both all-cause mortality and cardiovascular disease mortality. In contrast, consumption of instant coffee did not show a significant association with mortality risk reduction.

This study provides compelling evidence that moderate consumption of coffee, particularly freshly ground coffee, may confer significant health benefits, including reduced risks of mortality and cardiovascular disease. These findings highlight the potential role of coffee consumption in promoting heart-healthy lifestyles. However, further research is needed to fully understand the underlying mechanisms behind these observed associations.
