A “significantly reduced” mortality risk. A new study, published Tuesday in the European Journal of Preventive Cardiology, analyzed the benefits of coffee for the body. She concludes that drinking 2-3 cups of coffee a day, whether decaf, ground, or instant, is “associated with a significant reduction in cardiovascular events and mortality.”
“These results suggest that light to moderate consumption of ground, instant, and decaffeinated coffee should be considered part of a healthy lifestyle,” Peter Kistler of the Baker Heart and Diabetes Institute (Australia), one of the co-authors of the study.
The study was carried out with information provided by a cohort of 449,563 participants, with a median age of 58 years, extracted from the UK Biobank database. “It contains detailed health and genetic information on half a million British participants.” The median follow-up for this group “was 12.5 years,” state the authors.
27% less chance of death from two to three cups of ground coffee
The participants were divided into six groups: those who did not drink coffee, less than one a day, one, two to three, four to five and more than five cups a day. Of the almost 450,000 profiles selected for the study, 198,062 (44.1%) were consumers of instant coffee, 82,575 (18.4%) of ground coffee and 68,416 (15.2%) of decaffeinated coffee.
The results of each group were compared to understand the impact of coffee on health, and if the benefits of this drink are observed from one cup a day, they reach their peak with 2 or 3 cups. With higher consumption (4 cups or more), there are always benefits, but they are less and less important.
Compared to people who didn’t drink coffee, those who drank 2 to 3 cups of decaf a day had an average 14% lower chance of death, says Bloomberg. This same probability was 27% for two or three cups of ground coffee per day and 11% for instant coffee.
Even compared to the group of non-coffee drinkers, the risk of cardiovascular disease was reduced by 6% for decaf drinkers (2 to 3 cups per day), 20% for ground coffee drinkers, and 9 % for instant coffee. cluster.
On the other hand, “ground and instant coffee – but not decaf – were associated with a reduction in arrhythmia” in the participants.
Coffee is made of “more than 100 components”
It is still difficult to understand what element plays in favor of health in coffee. Coffee is a “complex alliance of more than 100 biologically active components, with caffeine being the most recognized,” the researchers stress. It is also part of the study to study in part the other components than decaf.
Coffee “also contains polyphenols,” antioxidants “and microelements such as magnesium,” says the study. However, “these constituents have been shown to reduce oxidative stress, modulate metabolism” or even “improve the gut microbiome.”
Several other studies prior to this one have already pointed to the benefits of coffee consumption on the body. In 2017, research found that “higher coffee consumption was associated with a lower risk of mortality from all causes, more particularly from diseases of the circulatory and digestive system.”
