Coffee may reduce risk of heart disease and early death, Australian study suggests

Drink 2-3 cups of most types per day coffee may protect you from Cardiovascular disease and early deatha new study found.

“These results suggest that light to moderate consumption of ground coffee, instant coffee, and decaffeinated coffee should be considered part of a healthy lifestyle.” said study author Peter Kistler, director of clinical electrophysiology studies at the Melbourne-based Baker Institute for Heart and Diabetes.

Researchers found that all three types of coffee “significantly reduced” the risk of coronary heart disease, congestive heart failure and stroke.

However, only caffeinated ground and instant coffee reduced the risk of arrhythmia, called arrhythmia.

Decaffeinated coffee did not reduce the risk, according to a study published in the European Journal of Preventive Cardiology.

Previous studies have also shown that moderate amounts of black coffee (3-5 cups per day) reduce the risk of heart disease, Alzheimer’s disease, Parkinson’s disease, type 2 diabetes, liver disease and prostate cancer. .

Charlotte Mills, Lecturer in Nutritional Sciences at the University of Reading, UK, said in a statement: “This manuscript adds to the body of evidence from observational studies linking moderate coffee consumption to cardioprotection. This is promising. It looks like.”

But like many past studies, the study is observational in nature and therefore cannot prove direct cause and effect, added Mills, who was involved in the study. I haven’t

“Does coffee make you healthy, or do inherently healthy people drink coffee?” she asked.

“Randomized controlled trials are needed to prove the relationship between coffee and cardiovascular health.”

The study used data from the UK Biobank, a research database containing the coffee consumption preferences of approximately 450,000 adults without arrhythmia or other cardiovascular disease at the start of the study.

They were divided into four groups: those who enjoyed caffeinated ground coffee, those who chose decaffeinated coffee, those who preferred caffeinated instant coffee, and those who did not drink coffee at all.

After an average of 12.5 years, researchers examined medical and death records for reports of arrhythmia, cardiovascular disease, stroke, and death.

After controlling for age, diabetes, ethnicity, hypertension, obesity, obstructive sleep apnea, gender, smoking status, and tea and alcohol consumption, the researchers found that all types of coffee reduced all-cause mortality. was found to be related to

The fact that both caffeinated and decaffeinated coffee were beneficial “could suggest that caffeine alone may not potentially explain the associated reduced risk.” Yes,” says Duane Mellor, registered dietitian and senior teaching fellow at Aston University School of Medicine, UK. .

“active ingredient”

“Caffeine is the best-known component of coffee, but coffee contains over 100 biologically active compounds,” says Kistler, professor of medicine at the University of Melbourne and Monash University. said Mr.

“Caffeine-free compounds are likely responsible for the observed positive relationship between coffee drinking and cardiovascular disease and survival,” Kistler said.

Those who drank two to three cups of coffee a day had the lowest premature mortality compared to those who did not drink coffee. Drinking ground coffee reduced the risk of death by 27%, decaffeinated coffee by 14%, and decaffeinated instant coffee by 11%.

The association between coffee and reduced risk of heart disease and stroke was not as strong: Drinking two to three cups of ground coffee a day reduced the risk by 20%, compared with the same amount of decaffeinated coffee. But the risk dropped by 6%, and it dropped instantly, 9 percent.

Data have changed regarding the effect of coffee on arrhythmia. Drinking four to five cups of caffeinated ground coffee a day lowered the risk by 17%, and drinking two to three cups of instant his coffee a day lowered the chance of arrhythmia by 12%.
