Scientists advise to give preference to ground, instant and decaffeinated types of coffee.
According to a new study from the Baker Heart and Diabetes Research Institute, Melbourne, Australia, drinking two to three cups of coffee a day is associated with increased life expectancy and reduced cardiovascular risk. disease.
“In this large observational study, ground, instant, and decaffeinated coffee were associated with equivalent reductions in CVD and mortality from CVD or any other cause,” said the study’s author. student Professor Peter Kistler.
Specifically, the greatest reduction in risk was seen at two to three cups per day. Moreover, ground coffee brought the greatest benefits. Drinking two to three cups of this beverage per day is associated with a 27% reduction in the likelihood of death and a 20% reduction in the likelihood of cardiovascular disease.
The study also examined the relationship between types of coffee and the occurrence of arrhythmias, cardiovascular disease and death using data from the British Biobank, which included adults aged 40 to 69 years. Cardiovascular diseases include ischemic heart disease, congestive heart failure, and ischemic stroke.
#449,563 participants without arrhythmias or other cardiovascular disease at baseline were included in the study. The average age of the participants was 58 years, 55.3% of them were women. Participants completed a questionnaire asking how many cups of coffee they drank each day and whether they usually drank instant, ground (eg cappuccino or filter coffee) or decaffeinated coffee. In addition, they are grouped into six categories of daily consumption, consisting of “none”, “less than one”, “one”, “two to three”, “four to five” and “more than five cups per day”, – noted the expert.
According to him, the regular type of coffee is instant in 198,062 (44.1%) participants, ground in 82,575 (18.4%) and decaffeinated in 68,416 (15.2%). Non-coffee drinkers who served as the control group consisted of 100,510 (22.4%) participants.
Coffee drinkers were compared with non-drinkers in terms of CVD, arrhythmias, and mortality after adjusting for age, ethnicity, sex, obesity, diabetes, high blood pressure, smoking status, obstructive sleep apnea, tea, and alcohol consumption. Outcomes information was obtained from medical records and death records.
A total of 27,809 (6.2%) participants died during follow-up. All subtypes of coffee were associated with reduced mortality from any cause. The greatest reduction in risk was seen in two to three cups per day, which when compared to no coffee drinking was associated with a 14%, 27% and 11% reduction in the likelihood of death for decaffeinated drinks, respectively. soil and instant preparation, respectively.
At the same time, during the observation period, cardiovascular diseases were diagnosed in 43,173 (9.6%) participants. But the lowest risk was seen in two to three cups a day.
“Caffeine is the most well-known component of coffee, but the drink contains more than 100 biologically active compounds. It is likely that decaffeinated compounds are responsible for the positive relationship observed between coffee consumption, cardiovascular disease and survival of life. Our results indicate that moderate amounts of all types of coffee should not be discouraged, but can be enjoyed as a heart-healthy habit,” Kistler concluded.
Recall that scientists from the Max Planck Institute for the Biology of Aging studied a drug called rapamycin. According to them, when applied correctly, it can prolong life. It is noted that physicians have been using it for more than 50 years as an immunosuppressant to prevent organ rejection.
