Do you enjoy sipping soft drinks? If yes, then you need to keep a check on your health as doctors came out with a new principle that soft drinks can rise the risk of cardiac arrest.  According to a latest medical study, cold drinks contain various preservatives and artificial flavours that can take health for a toll. It not only increases high blood pressure, but also damages the entires blood vessel system, the study stated. Researchers involved in this study came out with interesting factors. They said that people who consume more soft drinks have narrow blood vessels behind their eyes that’s a clear indication of damaged blood vessel system.  The study, however, made it clear that this damage has nothing to do with eye-vision.
