New study reveals you can drink up to 25 cups of coffee a day without causing heart problems

Coffee addicts rejoice – even drinking 25 cups a day is not bad for your heart, say scientists.

Previous studies have suggested the drink can stiffen arteries, with caffeine lovers often advised to cut down on their consumption.

But a study of more than 8,000 people across the UK found that drinking an average of five cups a day was actually no worse for their arteries than drinking less than a cup a day.

The research, which was part-funded by the British Heart Foundation, is being presented at the British Cardiovascular Society Conference in Manchester.

Experts from Queen Mary University of London divided 8,412 participants into three groups for their study.

The first group was made up of participants who drink less than one cup of coffee a day, the second contained those who drink between one and three cups a day, and the third was made up of people who drink more than three.

Some people drank up to 25 cups a day in the latter group – but the average was five cups a day.

Researchers found even those drinking the higher daily amounts were no more likely to have stiffening of arteries than those who drank less than one cup a day.
