- A study found a link between drinking coffee and a longer life.
- It also found that coffee was linked to a lower risk of cardiovascular disease.
- Two to three cups a day seems to be the ideal setting for these benefits.
- Experts say that coffee in moderation can be part of a heart-healthy lifestyle.
- However, they note that excessive coffee intake may increase the risk of adverse effects.
New research published in European Journal of Preventive Cardiology He found an association between drinking coffee and living longer.
The study also found that there was a low risk of cardiovascular disease.
Specifically, this effect was observed among those who drank about two to three cups of coffee per day.
All types of coffee, including ground, instant, and decaffeinated coffee, appear to provide this health benefit.
According to the authors, the aim of the study was to look at how drinking different types of coffee affects the risk of episodes of arrhythmia (arrhythmia), cardiovascular disease, and death.
To conduct the study, the researchers used data from UK Biobanka large, ongoing study providing researchers with medical and genetic data from nearly 500,000 volunteers between the ages of 40 and 69.
The average age of the subjects in the study was 58. Women made up 55.3% of the group.
Types of cardiovascular disease included coronary heart disease, congestive heart failure, and stroke.
In all, 449,564 subjects who did not have arrhythmia or cardiovascular disease at the start of the study were recruited.
Respondents were asked how many cups of coffee they drink per day, as well as what type of coffee they drink. They were then put into a category based on their level of consumption. There was also a group of non-coffee drinkers to compare.
Medical records and death records were used to assess the groups’ performance over time.
Follow-up researchers found that all types of coffee were associated with a lower risk of death from any cause. In addition, the greatest reduction in risk was observed in those who drank two to three cups per day.
Ground coffee was associated with the greatest reduction in risk, with a 27% lower risk of death compared to non-coffee drinkers.
Instant coffee provided the lowest risk reduction of 11%. However, all coffees seem to offer some protection.
When it comes to cardiovascular disease, all types of coffee have been linked to reduced cardiovascular accidents. This effect is also observed at a consumption level of two to three cups per day.
Ground coffee again provided the largest reduction in risk by 20%, while decaffeinated coffee provided the smallest reduction of 6%.
Both instant and ground coffee were associated with fewer cases of arrhythmias. However, decaffeinated does not appear to provide any benefit. The lowest level of risk was observed at four to five cups of ground coffee, while the effect was observed at a consumption level of two to three cups of instant coffee.
Dr.. Dipbrata MukherjeeD., chair of the Department of Internal Medicine and Professor of Internal Medicine at Texas Tech University Health Sciences Center in El Paso, who was not involved in this study, summed up: “This and other available data suggest that drinking modest amounts of coffee (two to three cups per day) Of all kinds it has some heart effects.”
Mukherjee said that although the study itself does not address this question, it may have something to do with the presence of caffeine in coffee.
Mukherjee said, “Caffeine has antiarrhythmic properties, particularly by inhibiting adenosine receptors (a chemical found in human cells). Endogenous adenosine shortens resistance periods in both the atrium (upper chamber of the heart) and ventricle (lower chamber of the heart) and thus increases resistance heart arrhythmia risk; by blocking adenosine receptors, caffeinated coffee may mitigate the effects of endogenous adenosine (present in the body) and protect against arrhythmias.”
This could explain why decaffeinated coffee affected the incidence of arrhythmias in this study differently, he said.
Mukherjee also noted that although caffeine is the most well-known ingredient in coffee, it actually contains more than 100 biologically active ingredients.
“It is possible that some non-caffeinated compounds are responsible for the benefits observed with coffee drinking, namely reduced cardiovascular disease and improved survival,” he explained.
Dr. Jim LiuA cardiologist at Ohio State University’s Wexner Medical Center advises that it’s best to drink coffee in moderation, noting that it’s generally safe and also has potential benefits for long-term cardiovascular health.
“Coffee is a stimulant, and it can have short-term effects such as high blood pressure and heart palpitations,” he warns.
“If someone is drinking large amounts or to the point where they are distressed by disturbing palpitations, sleep deprivation, or other negative effects, it is best to cut back,” he added.
He also advises people to be aware of what they add to their coffee, such as sugar. “Some coffee drinks and preparations contain large amounts of sugar and are high in calories, and consuming too much of it may negate the actual benefits of coffee itself.”
When it comes to people who don’t already drink coffee, Liu said he advises people to only drink it if they want to or enjoy it.
“Sure, drinking coffee has been associated with other health benefits, but if drinking coffee isn’t right for you, I wouldn’t force it just for the health benefits.”
If you choose to drink coffee in light of its potential health benefits, Liu noted that there are some side effects to be aware of.
“Coffee is a stimulant and can cause short-term effects such as high blood pressure and heart palpitations. It can also have negative effects on sleep.
If you take medications for high blood pressure, there may be some concerns as well. Caffeine may reduce the effect of some blood pressure medications, Liu said.
Mukherjee agreed with Liu’s remarks, noting that “all genres [of coffee] It has some heart-protective effects and can be enjoyed as part of a heart-healthy behavior.”
“I would suggest that people enjoy their coffee or tea (depending on preference) and lead a healthy lifestyle,” he said.
