Study shows that drinking up to 3 cups of coffee per day can lower the risk of death from stroke and heart attack.

An average of 2 billion cups of coffee is consumed daily across the world. Thus, making coffee one of the most consumed beverages in the world. Hence, the bitter concoction has gained quite a rapport among researchers and has been the centre of countless studies. Since drinking coffee often causes palpitations and increased heart rates among people, its effect on cardiovascular health is of great interest. In the past, coffee has been shown to reduce the risk of heart failure, liver disease, Parkinson’s disease, and even back pain. Now, new research has shown that coffee may also lower the risk of stroke and fatal heart disease.

To our knowledge, this is the largest study to systematically assess the cardiovascular effects of regular coffee consumption in a population without diagnosed heart disease.

Dr. Judit Simon at Heart and Vascular Centre at Semmelweis University in Budapest, Hungary presented the study’s data at the European Society of Cardiology Congress 2021.

The study aimed to assess cardiovascular effects of daily coffee consumption in a population with no signs of heart disease. The team of researchers recruited 468,629 participants part of the UK Biobank. These participants had no known heart disease and an average age of 56.2 years. They then followed the participants for a period of 10-15 years.

Moreover, the participants also underwent cardiac MRI scans for the assessment of heart structure and function.

Daily Consumption Equals Lower Risk

The researchers divided the participants according to their coffee intake: none, light-to-moderate (0.5 to 3 cups/day), and high (more than 3 cups/day). Approximately 19.5% drank more than 3 cups, 58% were light-to-moderate drinkers, and 22% did not drink any coffee.

Results showed that compared to zero coffee intake, light-to-moderate consumption had a 21% lower risk of stroke. They further has a 17% lower risk of death from cardiovascular disease, and a 12% lower risk of all-cause death.

Moreover, 0.5 to 3 cups of coffee per day was independently associated with lower risks of stroke, death from cardiovascular disease, and death from any cause.

Furthermore, MRI scans revealed daily consumption of coffee led to healthier hearts with better functioning. Therefore, study authors suggest that drinking up to 3 cups of coffee per day can have positive cardiovascular effects.
