Study: Up to 25 cups of coffee a day safe for heart health

Some previous studies have suggested that coffee stiffens arteries, putting pressure on the heart and increasing the likelihood of a heart attack or stroke, with drinkers warned to cut down their consumption.

But a new study of more than 8,000 people across the UK found that drinking five cups a day, and even up to 25, was no worse for the arteries than drinking less than a cup a day.
