A study has found that drinking two to three cups of coffee a day could be linked to a longer life.
The European Journal of Preventative Cardiology published their research on 27th September, named “The impact of coffee subtypes on incident cardiovascular disease, arrhythmias, and mortality“.
They looked at different coffee subtypes, such as decaf, ground and instant coffee, and then divided these into groups of Less than 1 cup, 1 cup, 2 -3 cups, 4-5 cups and more than 5 cups per day; and then compared this with people who don’t drink coffee.
A total of 449,563 participants (median 58 years, 55.3% females) were followed over 12.5 years (plus-minus 0.7 years).
Ground and instant coffee consumption was associated with a significant reduction in arrhythmia at 1–5 cups/day but was not found for decaffeinated coffee. The lowest risk was 4–5 cups/day for ground coffee.
The conclusion of the study was that decaffeinated, ground, and instant coffee, particularly at 2–3 cups/day, were associated with significant reductions in incident cardiovascular disease and mortality. Ground and instant but not decaffeinated coffee was associated with reduced arrhythmia.
