Coffee lovers might be able to breathe a sigh of relief—a new study found that drinking even large amounts of the caffeinated beverage won’t stiffen arteries and harm your heart.

하루에 커피 25잔 마셔도 건강에 문제없다

영국 런던퀸메리대학

   하루에 25잔의 커피를 마셔도 심장 건강에 이상이 없다는 연구결과가 나왔다고 영국의 BBC가 4일 보도했다.

영국 런던퀸메리대학의 연구진은 영국 심장학회의 의뢰를 받아 8412명을 상대로 연구를 진행한 결과, 하루에 커피를 25잔까지 마셔도 심장 건강에 큰 문제가 없다고 밝혔다.

연구진은 하루 한 잔 미만, 하루 1잔에서 3잔, 하루 3잔 이상을 마시는 그룹을 나눠 조사했다. 연구진은 이같은 방법으로 조사한 결과, 하루에 25잔의 커피를 마셔도 심장 건강에는 큰 문제가 없는 것으로 나타났다고 밝혔다.

이는 커피를 하루 6잔 이상 마시면 심혈관계 질환의 위험이 커진다는 이전 연구결과들을 뒤집는 것이다. 이전 연구는 커피를 많이 마시면 카페인이 혈관을 수축시켜 심장마비를 유발할 수 있다고 적시했다.

2018년 진행된 한 연구에서 커피를 마시면 커피를 마시지 않는 것보다 사망률이 조금 낮다는 결과도 있었다고 BBC는 전했다.

Aficionados have been getting mixed messages about their favorite drink, with some research suggesting that drinking coffee can improve health while other studies advise people to cut down on their consumption. Previous studies suggested that coffee can cause a stiffening of the arteries, putting pressure on the heart and increasing the likelihood of stroke or heart attack.

But a new study, funded in part by the British Heart Foundation, found that drinking five cups of coffee a day was no worse for the arteries than drinking less than one cup. The study of more than 8,000 people across the United Kingdom also found that even those who drank up to 25 cups a day were no more likely to experience stiffening of the arteries than someone drinking less than a cup a day.

In the latest study, which is being presented Monday at the British Cardiovascular Society conference, scientists from Queen Mary University of London divided 8,412 people into three groups, with each self-reporting its coffee consumption. The first group was made up of people who said they drank less than one cup of coffee a day; the second included those who drank between one and three cups; and the third group included those who drank more than three, with some in the group drinking up to 25 cups a day. People who consumed more than 25 cups of coffee a day were excluded.

All the participants in the study were given MRI heart scans and infrared pulse wave tests. Researchers corrected for factors such as age, gender, ethnicity, smoking status, weight, blood pressure, diet and how much alcohol a person drinks.

“What we found was that drinking more than three cups of coffee a day did not significantly increase the stiffness of blood vessels compared to people who drink one cup or less a day,” Kenneth Fung, who led the data analysis at Queen Mary University of London, told CNN.

“The main message for people to take away from this is that 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.”

Although some participants in the study drank 25 cups a day, the average intake among the highest coffee consumption group was five cups a day.

“We’re not telling people to drink 25 cups a day per se. If anything, if you drink within recommended guidelines, then we don’t expect to see an increase in arterial stiffness compared with those who drink one cup or less a day,” he added.

The research also showed that moderate and heavy coffee drinkers were most likely to be male, smoke and consume alcohol regularly.

Professor Metin Avkiran, associate medical director at the British Heart Foundation, said in a press release: “There are several conflicting studies saying different things about coffee, and it can be difficult to filter what we should believe and what we shouldn’t. This research will hopefully put some of the media reports in perspective, as it rules out one of the potential detrimental effects of coffee on our arteries.”
