How many cups of coffee per day protect the heart?
In a scientific development that could shift traditional perceptions of coffee consumption, a recent study has revealed a surprising link between drinking up to five cups of coffee daily and a significant improvement in cardiovascular health markers.
A news report based on this study noted that researchers monitored a large group of individuals over several years, concluding that regular coffee drinkers enjoyed cleaner arteries and more efficient hearts compared to non-consumers. These findings extend a series of studies aimed at understanding the complex effects of coffee on the human body.
The study, conducted by a team of cardiovascular researchers, showed that participants who consumed between three and five cups of coffee daily exhibited lower levels of calcium deposits in their coronary arteries.
In this context, researchers emphasized that the benefits were not limited to a specific age group, but applied to both men and women, with the best results recorded among those who maintained this level of consumption over extended periods.
The report added that the study relied on comprehensive health data from tens of thousands of adults who underwent advanced cardiac imaging tests. Researchers noted that the positive relationship between coffee and arterial health remained significant even after accounting for other factors such as smoking, physical activity levels, and overall diet. The source pointed out that these findings align with previous studies indicating that coffee is rich in polyphenols and antioxidants that combat inflammation in blood vessel walls.
Despite these encouraging results, researchers stressed the importance of paying attention to what is added to a cup of coffee. The report stated that health benefits diminish significantly when coffee is loaded with large amounts of artificial creamers, sugar, and sweetened flavorings. Experts also warned that the method of preparation plays a pivotal role, recommending filtered coffee over unfiltered boiled coffee, as paper filters remove natural oils known as diterpenes, which can raise cholesterol levels.
The report highlighted key points consumers should consider when interpreting these findings, summarized as follows:
• The study does not recommend that non-coffee drinkers start consuming it solely for heart health benefits, as other proven methods, such as exercise and vegetable consumption, offer similar advantages.
• Individual responses to caffeine vary based on genetic factors; some people experience heart palpitations or insomnia even with moderate amounts, necessitating medical consultation.
• The standard coffee cup in the study contained a moderate amount of caffeine, excluding the oversized beverages served by some commercial cafes, where a single cup may contain the equivalent of three to four regular cups.
• Pregnant and breastfeeding women should adhere to specific medical guidelines that set a safe caffeine intake limit significantly lower than five cups per day.
In this regard, researchers clarified that coffee is not just caffeine, but a complex mixture containing more than 1,000 biologically active compounds. The report noted that some of these compounds possess antioxidant properties superior to those found in fruits and vegetables. The source confirmed that future research will focus on isolating these compounds to understand their precise mechanisms of action within the body.
The report concluded that coffee, when consumed in moderation and in a healthy manner, can be part of a heart-healthy lifestyle rather than a burden on the heart, as was believed for decades. Experts emphasized that the key lies in listening to the body’s signals and avoiding overconsumption, which may cause nervous stress and sleep disturbances.
