Red Bull Gives Your Blood Pressure Wings
People who have high blood pressure might want to avoid energy drinks, because a new study suggests that they might interfere directly with blood pressure or hamper the effectiveness of medications. The drinks, which have high levels of caffeine and taurine ("an amino acid found in protein-rich foods like meat and fish that can affect heart function and blood pressure"), raise blood pressure and heart rates in healthy individuals, but not to dangerous levels. However, for people who have cardiovascular disease or are taking heart rate or blood pressure medication, the increase could be "significant."
The study doesn't point the finger directly at caffeine and taurine—they're just saying the drinks in their entirety seem likely to raise blood pressure. And the American Beverage Association Industry disagrees with the whole concept, releasing the following statement in response:
While the amount of caffeine in energy drinks or coffee may cause a slight and temporary increase in blood pressure, it would have no greater effect than walking up a flight of steps.
The researchers didn't reveal which energy drink they used in the study, but they pointed out that all of the drinks use pretty much the same basic ingredients. "By giving the brand, it would dilute the message that all of these drinks need to be looked at." We just picked Red Bull because that's the one slogan we actually know.

@peorgeum: Clean is 100% right. Between soda/energy drinks and the typical clean meaning, alcohol, I say alcohol is less worse for you. I have 0 scientic fact behind that opinion.
@humphrmi: I'm not sure if bottlers (or whatever they're called now) are doing this because of any requirement, but I have noticed caffeine content now being listed on sodas. Energy Fiend also has this information.
...a new study suggests that they might interfere directly with blood pressure or hamper the effectiveness of medications.
I think the "or" makes that statement misleading. To me it sounds like they found evidence that these drinks interfere with the medication independent of the fact that it raises your blood pressure. I read the article expecting them to say that something in these drinks stopped a chemical from doing what it needed to do but all they found was that the drink increased the blood pressure of healthy adults.
The "or" should be "and therefore" or it should be "and possibly".
@Papa Midnight:
Or Red Bull really does give you a tail...
Man, I did not like Red Bull the first time I tasted it... My teacher called it "bull urine." and I agreed.
Then again I think Dr. Pepper tastes like cough syrup...
These kinds of studies really tick me off. It's like saying "decongestants may make your BP go up" REALLY? I had no idea? Because I thought they were magic beans that just unclogged my nose. NO they are vasoconstrictors. Ugh. Caffine? stimulant. the amphetamine family stuff in energy drinks? Vaso? Hmmmmmmm. Why can't they study something more useful?













argh, they be stealing mah Rockstar!
(the caffeine of 5 Cokes in one can o'Rockstar, yeah!)
