Just one can of the popular stimulant energy drink Red Bull can increase your risk of heart attack or stroke. The effect was seen even in young people.
The caffeine-loaded beverage causes blood to become sticky, a pre-cursor to cardiovascular problems such as stroke.
One hour after drinking Red Bull, your blood system becomes abnormal, as might be expected from a patient with cardiovascular disease.
Red Bull is banned in Norway, Uruguay and Denmark because of health.
