A recent study stated that consuming a plentiful amount of coffee would not cause damage to the heart nor stiffen arteries. There are, however many contrasting arguments regarding the effects of consuming too much coffee.

The British Heart Foundation conducted a study involving more than 8000 people across the United Kingdom to study the effects of the caffeinated beverage, CNN reports. 

The study found that those who drink five to 25 cups of coffee a day face just the same risks as someone who drinks a cup a day.

Presented at the British Cardiovascular Society conference, the study, which was conducted by Queen Mary University of London, divided 8,412 people into three groups that were required to report their coffee intake.

The first group comprised people who claimed to drink less than one cup of coffee a day, the second consisted of people whose coffee consumption was no more than three cups, and the last group was made up of people who drink up to 25 cups a day.

MRI heart scans and infrared pulse wave tests were given to all participants, and then it was found that daily consumption of one cup of coffee or less, or more than three cups, did not significantly affect the stiffness level of blood vessels.

Kenneth Fung, leader of data analysis at Queen Mary University of London for the research, explained the finding to CNN.

“[…] coffee can be enjoyed as part of a healthy lifestyle, and coffee lovers can be reassured by this result in terms of blood vessel stiffness outcomes,” Fung was quoted as saying.

According to the research, however, the highest average amount of coffee consumed in a day was five cups, while daily consumption of up to 25 cups was rare.

“We’re not telling people to drink 25 cups a day per se,” said Fung, adding that if we drank within recommended guidelines, an increase in arterial stiffness was not to be expected, even when compared with those who only drink a cup of coffee daily or not at all. (vbp/mut)
