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.
Researcher Dr Scott Willoughby said: ‘One hour after they drank Red Bull, (their blood systems) were no longer normal.
‘They were abnormal like we would expect in a patient with cardiovascular disease.
‘If you get an increase in stickiness and a decreased ability of the blood vessels to stop its stickiness, that adds up to a bad situation.
‘If you add in other risk factors for cardiovascular disease - stress or high blood pressure - this could be potentially deadly.’
