Devices, methods, computer-readable media, and systems for determining an identity of a food are disclosed. For example, a method may receive at least one property of at least one component in a sample of a food from an intra-oral device including a spectrometer, the at least one property obtained via the spectrometer, compares the at least one property to a plurality of food signatures, and determines the identity of the food based upon the comparing. In another example, a system may include an intra-oral device and a wireless device. The intra-oral device may include a spectrometer for measuring at least one property of at least one component in a sample of a food. The wireless device may include a processor for receiving the at least one property, comparing the at least one property to a plurality of food signatures, and determining the identity of the food based upon the comparing.
