Key points from article :
A decade-long study included almost 500,000 people -- 22% were non-coffee drinkers, and 58% drank between up to three cups a day.
Over the study period, subjects who drank 0.5-3 cups of coffee per day were 12% less likely to die compared to non-coffee drinkers.
17% and 21% less likely to die from cardiovascular disease and stroke; less likely to be diabetic than zero-coffee drinkers.
As caffeine is an appetite suppressant, it could lead to lower rates of obesity and other related conditions.
Exceeding 3 cups a day had no additional positive impact.
The quarter of the group who consumed instant coffee, did not have any health benefits.
Those who consumed moderate-high caffeinated drinks had larger ventricles, thus could pump out more blood.
Moderate coffee consumption “is not cardiovascularly harmful and may even be beneficial” - Steffen Petersen, co-author of the study.
