In people without a diagnosis of heart disease, regular coffee consumption of 0.5 to 3 cups of coffee per day was associated with a decreased risk of death from heart disease, stroke, and premature death from any cause. cause compared to non-coffee drinkers.
The study, presented at the annual meeting of the European Society of Cardiology on Friday, looked at the coffee drinking behavior of more than 468,000 people participating in the UK Biobank study, which contains in-depth genetic and health information about over half a million Britons. .
Compared to people who didn’t drink coffee, the April analysis found that the risk of heart failure over time decreased between 5% and 12% for each cup of coffee consumed each day in two of the studies.
The risk of heart failure remained the same for not drinking coffee or a cup per day in the third study. But when people drank two or more cups of black coffee a day, the risk was reduced by about 30%, according to the analysis.
“The association between caffeine and reduced risk of heart failure was surprising,” said senior author Dr. David Kao, medical director of the Colorado Center for Personalized Medicine at the School of Medicine, in April. University of Colorado at Aurora.
“Coffee and caffeine are often considered by the general population to be ‘bad’ for the heart, as people associate them with palpitations, high blood pressure, etc. The consistent relationship between increased caffeine intake and decreased risk of heart failure overturns this assumption. “Kao said in a statement.
In the April study, the benefits did not extend to decaffeinated coffee. Instead, the analysis found an association between decaffeinated coffee and an increased risk of heart failure.
“While it is impossible to prove the causal link, it is interesting that these three studies suggest that coffee consumption is associated with a decreased risk of heart failure and that coffee may be part of a healthy diet if eaten plain, with no added sugar or high fat dairy products like cream, ”said dietitian Penny Kris-Etherton, past chair of the Heart Health and Fashion Council steering committee from the American Heart Association, in a statement released in April She was not involved in the research.
A little bit of caution
Many studies on coffee are done only on the consumption of black coffee. However, adding dairy, sugars, flavors, or non-dairy creams can add a lot of calories, sugar, and fat, which could negate coffee’s heart health benefits, he advised. AHA.
One more caveat: In most studies, one cup of coffee is only 8 ounces. But the standard “tall” coffee cup is 16 ounces.
The way you prepare your coffee can also affect the health benefits of coffee. The filtered coffee grabs a compound called cafestol which exists in the oily part of the coffee. Cafestol can increase your bad or LDL (low density lipoprotein) cholesterol.
However, if you use a French press, Turkish coffee maker, or boil your coffee (as is often done in Scandinavian countries), cafestol is not removed.
And, finally, the benefits of coffee don’t apply to children – even teens shouldn’t drink colas, coffees, energy drinks, or other caffeinated drinks, according to the American Academy of Pediatrics.
