Just recently, presented at the Radiological Society of North America, German researchers were able to image increased cardiac motility 1 hour after test subjects consumed popular energy drinks. The drinks contained 400 mg taurine and as much as caffeine as up to two cups of coffee. The increased cardiac motility is not surprising, given that caffeine itself can lead to irregular heartbeats and palpitations. What this does confirm however, is that physically, the heart works harder, specifically 6% harder after drinking energy drinks, according to Dr. Jonas Doerner with the University of Bonn, Germany. Increased heart contractility in those with underlying cardiac issues would be more prone to potentially adverse effects. In recent years, there has been a series of deaths and emergency events associated with the consumption of these caffeine and taurine-based energy drinks. What is surprising from this study is that a control group, just utilizing caffeine at the same dose, did not show increased cardiac contractility. This potentially shows that the potential synergistic effects of caffeine, taurine, and potentially sugar can lead to amplified effects, which can affect heart function.
Here’s my advice on how to stay focused without energy drinks:
- First, minimize your sugar intake. Refine sugar can have a deleterious effect on your body.
- Second, stay up to date on the latest studies of what you eat or drink. Science and medicine have a certain truth to it. If more than a few research studies have shown certain things, it is starting to look like it may be real.
- Third, go stimulant-free. Caffeine acts on your neuroreceptors, which get saturated over time. That is why over time you need more of it for it to work. Going stimulant free and choosing a judicious supplement program allows you to go for the long haul.
Stay focused and be well.
