More than 2.25 million cups of coffee are consumed every day around the world and its benefits only extend its fame.
Drinking 3 to 5 cups of coffee (both regular and decaffeinated) a day would reduce our chances of dying prematurely , according to a new study led by researchers from the Harvard TH Chan School of Public Health at Boston University, Massachusetts (USA). USA).
The scientists carried out an analysis of the data obtained in three macro studies: the first, with 74,890 women; the second, with 93,054 women and, the third, with 40,557 men. All the participants were nurses. Thanks to the questionnaires completed by the volunteers, their coffee consumption was studied for approximately 30 years. During the study’s follow-up, 19,524 women and 12,432 men died.
Discarding variables such as smoking, alcohol consumption, body mass index (BMI) or physical exercise, the results revealed that those who drank 3-5 cups of coffee a day were less likely to die prematurely from certain diseases such as type 2 diabetes, cardiovascular diseases, neurological diseases (such as Parkinson’s) or even death by suicide , compared to those who did not drink coffee or took it in lower doses.
Among the conclusions of the work, the experts state that one of the explanations for this benefit could be due to the bioactive compounds present in coffee that reduce insulin resistance and systematic inflammation .
“ Regular consumption of coffee can be included as part of a healthy and balanced diet. However, certain populations, such as pregnant women and children, should be careful with high caffeine consumption from coffee or other beverages, ”explains Frank Hu, co-author of the study.
The study has been published in the journal Circulation .
