This is how drinking 3 cups of coffee a day benefits our heart


The coffee is one of the drinks best known and consumed in the world. Due to its content in caffeine, allows those who consume it daily to activate them and start the day with the greatest of energies. In this article we are going to see how it benefits to drink up to 3 cups of coffee a day at Health of our heart.

Numerous investigations indicate the effects that coffee has on health, especially on the cardiovascular health. In fact, a study carried out by the University of California found the risk of suffering arrhythmias did not increase with moderate consumption of coffee.

And now it has been research presented at the Congress of the European Society of Cardiology ESC 2021. That study pointed out that up to three cups of coffee a day are associated with a lower risk of stroke and fatal heart disease. The author of the study was Judit Simon, from the Cardiovascular Center of the Semmelweis University in Budapest (Hungary).

“To our knowledge, this is the largest study systematically evaluating the cardiovascular effects of regular coffee consumption in a population without diagnosed heart disease,” Judit Simon noted.

Caffeinated coffee to lower triglycerides

“Our results suggest that regular coffee consumption is safe, as even high daily intake was not associated with adverse cardiovascular outcomes or all-cause mortality after 10-15 years of follow-up.” A study that is still ongoing.

Additionally, as the author notes, 0.5 to 3 cups of coffee a day was independently associated with several benefits:

  • Lower risk of stroke
  • Death from cardiovascular disease
  • Death from any cause

Few data on the long-term impact of coffee on cardiovascular health

Even though that him coffee It is one of the most widely consumed beverages in the world, little is yet known about the long-term impact of its regular consumption on cardiovascular health.

This study investigated the association between habitual coffee intake and incidents of heart attack, ictus and death. The research included 468,629 UK Biobank participants with no signs of heart disease at the time of recruitment. The mean age of the sample was 56.2 years and 55.8% were women.


The participants were divided into three groups according to their habitual coffee consumption:

  1. None (did not consume coffee regularly, 22.1%)
  2. Light to moderate (0.5 to 3 cups / day, 58.4%)
  3. High (more than 3 cups / day, 19.5%).

The researchers adjusted the analysis based on the factors that could influence the relationship: age, sex, weight, height, smoking, physical activity, high blood pressure, diabetes, cholesterol level, socioeconomic status, and habitual intake of alcohol, meat , tea, fruits and vegetables.

Lower risk of stroke and fatal heart disease when drinking coffee

The conclusions that the researchers drew were that in the group of non-drinkers of coffee, light to moderate consumption was associated with a 12% lower risk of death from all causes, a 17% lower risk of death from cardiovascular disease, and a 21% lower risk of stroke.

To examine possible underlying mechanisms, the researchers analyzed the relationship between daily coffee intake and the structure and function of the heart during a mean follow-up of 11 years. To do this, they used data from 30,650 participants who underwent cardiac magnetic resonance imaging (MRI), considered the gold standard for evaluating cardiac structure and function.

Study author Judit Simon noted that analysis of the images indicated that daily users had healthier-sized hearts and that they performed better, compared to participants who did not drink coffee regularly.

For this reason, he stressed that “this was consistent with the reversal of the damaging effects of aging on the heart. Our results suggest that coffee consumption of up to 3 cups a day is associated with favorable cardiovascular outcomes.

Of course, he concludes stating that “more studies are needed to explain the underlying mechanisms, the observed benefits could be partly explained by the positive alterations in cardiac structure and function.”
