A hospital study says drinking red bull can increase your risk of heart attack, but the makers of red bull say it's not any more harmful than a cup of coffee.Researchers in Australia tested 30 young adults to see how drinking a can of Red Bull affected their cardiovascular systems.

After one can, researchers say the subjects had symptoms usually associated with heart disease.

Researchers say those symptoms, when combined with stress or high blood pressure, make people more vulnerable to strokes and heart attacks.

The makers of Red Bull say the drink is safe, but do warn people not to drink more than two cans a day.
