According to a new study, drinking two to three cups of coffee per day is associated with a lower risk of cardiovascular disease as well as an increased likelihood of living a longer life.
Coffee drinkers who consumed two to three cups of coffee daily had a lower risk of cardiovascular disease and a longer expected lifetime when compared to non-coffee drinkers. This is the case, according to new research published on September 27 in the European Journal of Preventive Cardiology, a journal published by the European Society of Cardiology (ESC). The improved longevity findings apply to all types of coffee, including ground coffee, instant coffee, and decaffeinated coffee.
According to the study’s lead author, Professor Peter Kistler, “ground, instant, and decaffeinated coffee were associated with equivalent reductions in the incidence of cardiovascular disease and death from cardiovascular disease or any cause in this large, observational study.” His work at Melbourne’s Baker Heart and Diabetes Research Institute has established him as a world-renowned expert in cardiac arrhythmia research. Drinking ground, instant, or decaffeinated coffee on a light to moderate basis should be considered part of a healthy lifestyle, according to the findings.
According to the study’s findings, drinking any type of coffee was associated with a lower risk of dying from any cause. The highest risk reduction was seen with two to three cups of coffee per day, and ground coffee was the most beneficial form of coffee. Consuming two to three cups of ground coffee per day was linked to a 27% lower risk of dying from any cause and a 20% lower risk of developing cardiovascular disease.
Previously, there was a lack of understanding about the effect that various coffee preparations have on the health and longevity of the heart. As a result, the goal of this study was to look into the links between various types of coffee and the occurrence of arrhythmias, cardiovascular illness, and death. The data for this study came from the UK Biobank, which included people aged 40 to 69. Cardiovascular disease refers to a group of conditions that includes coronary heart disease, congestive heart failure, and ischemic stroke.
All 449,563 participants were evaluated at the start of the trial and found to be free of any arrhythmias or other cardiovascular disorders. The participants’ average age was 58, and 55.3% of them were female. The participants were given a questionnaire to complete, which asked how many cups of coffee they drank on a daily basis and whether they drank instant coffee, ground coffee (such as cappuccino or filtered coffee), or decaffeinated coffee.
Furthermore, they were divided into six categories based on their daily consumption, which included none, less than one, one, two to three, four to five, and more than five cups per day. Participants consumed instant coffee in 198,062 cases (44.1%), ground coffee in 82,575 cases (18.4%), and decaffeinated coffee in 68,416 cases (15.2%). Individuals who did not drink coffee made up 100 510 (22.4% of all participants) and served as the comparison group.
Coffee drinkers were compared to non-drinkers in terms of the incidence of cardiovascular disease, arrhythmias, and death after taking into account factors such as age, ethnicity, sex, obesity, diabetes, high blood pressure, smoking status, obstructive sleep apnea, and tea and alcohol consumption. This comparison was made after adjusting for tea and alcohol consumption. The outcome was determined using information from the patient’s medical records as well as death records. The average amount of time spent following up was 12.5 years.
During the follow-up period, 27,809 (6.2%) of the participants died. Consumption of any type of coffee was linked to a lower risk of death from any cause. When compared to not drinking coffee, drinking two to three cups per day was associated with a 14%, 27%, and 11% lower risk of death, respectively, depending on the type of coffee preparation consumed (decaffeinated, ground, or instant). This was the level of coffee consumption that reduced the most risks.
Patients with cardiovascular disease were identified in 43,173 (9.6%) of the total during the follow-up. It has been demonstrated that drinking any type of coffee is associated with a lower risk of developing cardiovascular disease. Again, two to three cups per day were associated with a 6%, 20%, and 9% lower incidence of cardiovascular disease when compared to abstaining from coffee. This was true for decaffeinated, ground, and instant coffee, in that order.
An arrhythmia was discovered in 30,100 (6.7%) of the study’s participants during the follow-up. Drinking ground and instant coffee, but not decaffeinated coffee, was associated with a lower risk of arrhythmias, including atrial fibrillation. When compared to non-drinkers, the lowest risks were reported with four to five cups of daily ground coffee consumption and two to three cups of daily instant coffee consumption, with 17% and 12% lower risks, respectively. This applied to both types of coffee.
“Caffeine is the most well-known element in coffee,” says Professor Kistler, “but the beverage contains more than one hundred biologically active components.” The non-caffeinated components are most likely responsible for the beneficial associations found between coffee consumption, cardiovascular disease, and survival. Our research suggests that drinking coffee, tea, or cola in moderation is not only acceptable, but may even be appreciated as a heart-healthy practice.
