Some studies have suggested that drinking too much coffee can cause stiffening of the arteries, increasing the chance of suffering a heart attack or stroke. However, a new study from the British Heart Association, reported that drinking 3 cups of coffee or more a day is no worse for arteries than drinking a single cup.
Researchers studied more than 8,000 people in the UK, some of whom drank 1 cup of coffee or less a day, others who drank 1 to 3 cups, and a third group who reported consuming up to 20 cups of coffee a day.
All participants were given extensive tests and the findings appear to show that drinking 3 cups or more a day doesn’t significantly increase artery stiffness compared with consuming just one cup.
No one is recommending having 20 cups or more per day! However, if you do enjoy a cup or two maybe even three per day, you should not be at any additional risk of heart issues.
