This Sensor Helps You Watch What You Eat

Scientists at the Tufts University School of Engineering in Medford, MA have invented a sensor that helps you monitor what you eat. Until recently, the ability to accurately track your daily food intake has been fairly unreliable. This device is a 2mm square that can bond to the surface of your tooth.  At the moment it will only collect information on your salt, glucose and alcohol consumption however they are hoping they will be able to detect a whole array of chemicals and nutrients in the future. They also say that with the ability of picking up chemicals in saliva, they may be able to rate stress levels well.
