A study by Willoughby (2009) showed that symptoms associated with cardiovascular disease occurred to normal people after drinking Red Bull. In his study, he put 30 young adults to the energy drink test. His experimental methodology was to test the subjects one hour before and one hour after drinking one 250 ml can of sugar free Red Bull. His result was surprising that an hour after the energy drink consumption, the cardiovascular systems were “no longer normal but behaved more like patients with heart disease”. Willoughby (2009) also mentioned, “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.” While his study was quite simple in his methodology, there were some questionable procedures that need to be considered. He did not stress on the measurement of symptoms or the test results of the volunteers after consuming Red Bull as compared to those who had cardiovascular disease. In addition, no control procedure on patients’ diet programs and their health conditions before and after the experiment were recorded. These overlooked procedures might have led to mislead conclusions.
