The most interesting infographic just came out from HellaWella regarding the caffeine amounts in popular soda brands. I am not a huge soda drinker, though I do enjoy the occasional Diet Dr. Pepper, but I was intrigued by this study nonetheless. A lot of my friends are soda fans and drink it regularly and I wonder if they understand just how much caffeine hey are ingesting. Take a look at this ranking and see how much caffeine you are ingesting each day. Is it too much? Perhaps you should cut back? Or, maybe you’ll be pleased with what you find!
