Red Bull banned in Denmark

Just one can of Red Bull could raise the risk of heart attack or stroke, even in young people, researchers have warned.
A study of university students found drinking one 250ml can of the sugar-free version of the energy drink that 'gives you wings' increased the 'stickiness' of the blood and raised the risk of life-threatening clots.

Dr Willoughby, of the Cardiovascular Research Centre at the Royal Adelaide Hospital, said he was 'alarmed' at the results and would not drink Red Bull himself.

Those with underlying heart or circulatory problems should think twice before buying the caffeine-loaded drink, he said.

The results, reported in the Australian newspaper, also shocked the students taking part, some of whom drank up to eight cans a night to help them stay awake to study. Many now refuse to drink Red Bull again.

Red Bull is banned in Norway, Uruguay and Denmark because of health fears, but the company last year sold 3.5 billion cans and bottles in 143 countries.

In Britain alone, it has sales of £271 million a year, with much of the cash spent in bars and clubs were it is a popular mixer with vodka and other spirits.

Previous studies have warned the stimulant effect of Red Bull can mask some of the tell-tale signs of drunkenness - putting revellers at risk of injury and attack because they do not realise how intoxicated they are.
